DECISION ON APPEAL2

STATEMENT OF CASE
Appellant appeals under 35 U.S.C. § 134(a) the Examiner’s decision
to reject claims 1–9. We have jurisdiction under 35 U.S.C. § 6(b).

1 Appellant identifies the real party in interest as PBO, Inc. Appeal Br. 3.
2 In our opinion below, we reference the Specification filed May 19, 2010
(Spec.), the Amendment to the Specification filed December 3, 2012
(Amdt.), Final Office Action mailed December 19, 2012 (Final), the Appeal
Brief filed December 19, 2013 (Appeal Br.), the Examiner’s Answer mailed
February 3, 2014 (Ans.), and the Reply Brief filed April 3, 2014 (Reply Br.).

Application 12/783,503

2
We AFFIRM-IN-PART, and denominate our affirmance as involving
a new ground of rejection under 37 C.F.R. § 41.50(b).
The claims are directed to a textile, and a fabric. Claims 1 and 7 are
illustrative:
1. A textile, comprising a tobacco plant fiber derived
from a tobacco plant.
7. A fabric, comprising a textile consisting essentially of
a tobacco plant fiber derived from a tobacco plant.
Claims Appendix, Br. 25.
In the Final Office Action, the Examiner:
A. Objects to the amendment filed December 3, 2012 under
35 U.S.C. § 132(a) because it introduces new matter into the
disclosure;
B. Rejects claims 1, 2, and 4–8 under 35 U.S.C. § 102(b) as
anticipated by Philip Morris3;
C. Rejects claims 1, 2, 4, 7, and 8 under 35 U.S.C. § 102(b) as
anticipated by Seidel4; and
D. Rejects claims 3 and 9 under 35 U.S.C. § 103(a) as obvious over
Philip Morris in view of Nakanishi.5
The Examiner maintains the objection and rejections on appeal. Ans.

The Examiner objects to the amendment of a particular paragraph
within the Specification, finding that it introduces new matter. Final 2.
Appellant argues that the Examiner erred in objecting to the amendment of
the paragraph. Appeal Br. 8–12; Reply Br. 7–8. We do not have
jurisdiction to review the objection.
Our jurisdiction extends to the review of rejections of claims, and
those matters at least indirectly relating to matters involving those rejections.
35 U.S.C. §§ 6(b) and 134(a) (2010); In re Hengehold, 440 F.2d 1395, 1404,
(CCPA 1971). While as stated in MPEP § 706.01, we do not review formal
matters such as the form of a claim (as contrasted with its substance), there
are situations in which we review objections that relate at least indirectly to
matters involving rejections. For instance, if both the claims and
specification contain new matter either directly or indirectly and there has
been both a rejection for lack of written descriptive support and an objection
to the new matter by the examiner, the objection is decided along with the
rejection on appeal. MPEP § 2163.06 (II) (8th ed., rev. 9, August 2012).
This makes sense not only because the rejection and objection are related,
but because upholding a new matter objection that affects the claims would
deny an applicant the ability to patent those claims. Any action by an
examiner that would deny patentability of a claim is, in essence, a rejection
of that claim and an “adverse decision” with respect to that claim. Such
“adverse decisions” are appealable under 35 U.S.C. § 134(a). See, e.g., In re
Haas, 486 F.2d 1053, 1055–56 (CCPA 1973) (examiner’s withdrawal of
claims from consideration as being inclusive of multiple patentable distinct
inventions was in effect a de facto rejection because it denied the applicant
Appeal 2014-005529
Application 12/783,503

4
the ability to have claims of the identical scope examined in any
application).
Although in the present appeal the question involved in the objection
may have some influence on the interpretation of the claims rejected over
prior art, i.e., the rejections under 35 U.S.C. §§ 102(b) and 103(a), our
decision regarding the prior art rejections renders that influence nominal.
Thus, given the nominal impact of the amendment on the rejections under
our jurisdiction, the objection does not amount to a rejection of the claims
and it would not be proper for us to review the objection, the review of
which is normally under the authority of the Director. See MPEP § 1201
(The line of demarcation between appealable matters for the Board and
petitionable matters for the Director should be carefully observed.).
Thus, we do not reach the objection as it is outside our jurisdiction to
review it.
Anticipation by Philip Morris
The Examiner rejects claims 1, 2, and 4–8 under 35 U.S.C. § 102(b)
as anticipated by Philip Morris.
All of the rejected claims are directed to either a textile or a fabric.
See, e.g., claims 1 and 7.
The Examiner finds that Philip Morris describes “a mass of tobacco
plant fibers that have been washed with water and separated into
individualized fibers.” Final 4, citing Philip Morris, p. 5, ll. 21–31. The
Examiner finds that these fibers “are intertwined and interlocked with one
another, thus forming a textile or fabric material.” Final 4, citing Philip
Morris, p.5, ll. 88–100. The Examiner further finds that Philip Morris uses
Appeal 2014-005529
Application 12/783,503

5
the same processing steps as Appellant to create the tobacco products, thus
the product must be the same. Ans. 8–9.
We agree with Appellant that the Examiner reversibly erred.
Philip Morris does not use the terms “textile” or “fabric,” but instead
describes, in the most relevant embodiment, forming a base film for
supporting leaf tobacco. Philip Morris 1:42–71. In other portions of the
disclosure, Philip Morris uses the terms “sheet” and “binder” to describe the
product. Philip Morris 1:48–52, 5:82–87, 6:125–127, 7:46–50.
To obtain the base film or sheet, Philip Morris cuts lengths of tobacco
stems to an average length of about one inch, soaks and treats them to
soften, swell, and loosen the fibers, and conducts a refining operation that
mechanically beats the material to separate the bundles of fibers into more or
less individual fibers, and to fibrillate and hydrate the individual fibers.
Philip Morris 2:13–39, 2:105–108. The refining operation reduces a portion
of the fibers to a colloidal or gelatinous state and retains another portion as
discrete fibers of “substantial” length that are at least partially fibrillated.
Phillip Morris 5:60–66. The fibers have a length in excess of 0.2 mm.
Philip Morris 5:71–74. Preferably, 35% or 40% at least should have a length
in excess of 0.3 mm. Philip Morris 5:117–122. Thus, the “substantial”
length is a length of 0.2 mm, 0.3 mm, or an excess of 0.3 mm.
The resulting slurry contains 94-97 parts water, 2-3.5 parts gelatinous
material, and 1-2.5 parts fiber. Philip Morris 5:124–130. The ratio of fibers
to gelatinous material is in the range of 1:3 to 3:3. Philip Morris 6:1–3.
Philip Morris discloses forming a sheet from the slurry by flowing the
slurry onto a moving belt along with layers of ground tobacco, and drying.
Philip Morris 6:127–7:45. In the process shown in Figure 1, the web passes

through a dryer 67, moistener 68, and is rolled up at 69. Philip Morris 7:7–
21.
When dried, the fibers are intertwined with each other and the
gelatinous portions act as an adhesive binder to create a product with fibers
more of less uniformly distributed and interlocking in an adhesive material.
Philip Morris 5:93–105.
As argued by Appellant, the fibers are short, on the order of 0.2 and
0.3 mm or somewhat longer. The product is also either equal parts adhesive
material and fibers or mostly adhesive material.
On the one hand, Appellant produces evidence tending to show that
textiles and fabrics are made from fibers longer than those disclosed by
Philip Morris. See, e.g., Exhibit A, Final Report – Phase One to Ploughboy
Organics LLC dated May 4, 2012 (Report). In the Report, Dr. Watson, an
expert in the textile art,6 describes a project for devising a method to extract
fibers to test the fiber’s suitability for use in spun yarn that can be converted
into knitted or woven fabrics. Exhibit A, Report p. 4 ¶ 1. These products
are also referred to as “textile products.” Exhibit A, Report p. 4 ¶ 2. The
Report further discloses that “[t]o be considered a Textile Grade fiber,” a
fiber must have high length to diameter ratio (at least 1000:1), low bending
rigidity, and small diameter (10 to 200 microns). Exhibit A, Report p. 5–6.
On the other hand, the Examiner, presents definitions of “textile” and
“fabric” that do not refute Dr. Watson’s statement about fiber length.
As found by the Examiner, the “Complete Textile Glossary, Celanese
Acetate LLL, 2001, defines “Textile” as follows:

6 Declaration of Richard A. Ryan, dated December 3, 2012, ¶¶ 7–11.
Appeal 2014-005529
Application 12/783,503

TEXTILE: Originally, a woven fabric; now applied
generally to any one of the following: 1. Staple fibers and
filaments suitable for conversion to or use as yarns, or for the
preparation of woven, knit, or nonwoven fabrics. 2. Yarns made
from natural or manufactured fibers. 3. Fabrics and other
manufactured products made from fibers as defined above and
from yarns. 4. Garments and other articles fabricated from
fibers, yarns, or fabrics when the products retain the
characteristic flexibility and drape of the original fabrics.
Ans. 8.
The Examiner also finds that the Complete Textile Glossary defines
“Fabric” as “[a] planar textile structure produces by interlacing yarns, fibers,
or filaments.” Ans. 8.
Although the definition of “textile” cited by the Examiner, allows
textiles to be staple fibers, the staple fibers must be “suitable for conversion
to or use as yarns” or be for the preparation of, for instance, nonwovens.
But the evidence is insufficient to show that the short fibers of Philip Morris
can be converted to yarns. Nor does the evidence support a finding that the
wet-laid sheets of Philip Morris, which contain 50% or more adhesive and
short fibers are nonwovens.
A preponderance of the evidence supports Appellant’s position that
the product sheets of Philip Morris are not a fabric, nor are the fibers long
enough to be meet the requirements of being a “textile” as that term is
understood in the art.
We do not sustain the rejection of claims 1, 2, and 4–8 as anticipated
by Philip Morris.
Obviousness over Philip Morris in view of Nakanishi
The Examiner rejects claims 3 and 9 under 35 U.S.C. § 103(a) as
obvious Philip Morris in view of Nakanishi, relying on Philip Morris in the
Appeal 2014-005529
Application 12/783,503

8
same capacity as in the anticipation rejection. This rejection suffers from the
same defects as the anticipation rejection. Thus, we do not sustain the
obviousness rejection.
Anticipation by Seidel
The rejection of claims 1, 2, 4, 7, and 8 as anticipated by Seidel stands
on a different foundation. As found by the Examiner, Seidel expressly
discloses a “[n]on-woven fabric containing tobacco,” formed by carding fine
cut fibers to form a fibrous web and bonding the web to form the nonwoven
fabric. Seidel, Abstract. Given that Seidel expressly states that the product
is a nonwoven fabric, it is a fabric. Given that Seidel forms the fabric from
fibers, the fibers meet the definition of a textile, i.e., “[s]taple fibers and
filaments suitable . . . for the preparation of . . . nonwoven fabrics,” as
defined by the Complete Textile Glossary.
Appellant speculates that the non-woven of Seidel, because it is “used
as tobacco portions for making self-rolled cigarettes,”7 is a type of thin
paper-like sheet that is used to make rolling paper for handmade cigarettes.
Appeal Br. 19. But there is no convincing evidence that this is the case. In
fact, it appears that the nonwoven is used as the interior of the cigarette. We
provide a copy of the full German document, and a machine translation,
indicating that the nonwoven is truly a textile fabric, not a paper.
Translation ¶ 15 (indicating that it is not just the usual textile fibers such as
wool or cotton that can be processed into a nonwoven fabric, but also
tobacco); ¶ 16 (“The processing of tobacco into a nonwoven fabric can be
carried out on conventional machines in principle, as they are well known in
textile technology.”)(bolding omitted); ¶ 22 (The nonwoven is a square

Appeal 2014-005529
Application 12/783,503

9
lengthwise strand of fleece material around which one rotates a cigarette
paper).
Further, we do not agree with Appellant that Seidel’s nonwoven fabric
is different from that claimed. Appeal Br. 20. Seidel’s fibers are formed
using traditional textile machinery and long fibers. See, e.g., Seidel
translation ¶¶ 13, 14, 16, 17, 26, and 28. Appellant urges that the nonwoven
fabrics of Seidel are different from woven and knitted fabrics, but as evinced
from the definitions reproduced above from the Complete Textile Glossary,
“textiles,” and “fabrics” include fibers suitable for conversion to nonwoven
fabrics and the fabrics that result. Appellant’s claims are not limited to
woven and knitted fabric.
We sustain the rejection of claims 1, 2, 4, 7, and 8 as anticipated by
Seidel. Because we rely upon the newly introduced German patent, and its
translation, we denominate the affirmance as involving a new ground of
rejection so that Appellant may have a chance to respond to the new
evidence.

CONCLUSION
We sustain the rejection of claims 1, 2, 4, 7, and 8 under 35 U.S.C.
§ 102(b) as anticipated by Seidel and in so doing denominate it as involving
a new ground of rejection.
We do not sustain the Examiner’s rejection of claims 1, 2, and 5–8
under 35 U.S.C. § 102(b) as anticipated by Philip Morris, or the rejection of
claims 3 and 9 under 35 U.S.C. § 103(a) as obvious over Philip Morris in
view of Nakanishi.

DECISION
The Examiner’s decision is affirmed-in-part.

TIME PERIOD FOR RESPONSE
No time period for taking any subsequent action in connection with
this appeal may be extended under 37 C.F.R. § 1.136(a)(1).
This decision contains a new ground of rejection pursuant to
37 C.F.R. § 41.50(b), which provides that a “new ground of rejection
pursuant to this paragraph shall not be considered final for judicial review.”
37 C.F.R. § 41.50(b) also provides that the appellant, WITHIN TWO
MONTHS FROM THE DATE OF THE DECISION, must exercise one of
the following two options with respect to the new ground of rejection to
avoid termination of the appeal as to the rejected claims:
(1) Reopen prosecution. Submit an appropriate
amendment of the claims so rejected or new evidence relating to
the claims so rejected, or both, and have the matter reconsidered
by the examiner, in which event the proceeding will be remanded
to the examiner. . . .

(2) Request rehearing. Request that the proceeding be
reheard under § 41.52 by the Board upon the same record. . . .

Should the appellant elect to prosecute further before the Examiner
pursuant to 37 C.F.R. § 41.50(b)(1), to preserve the right to seek review
under 35 U.S.C. §§ 141 or 145 with respect to the affirmed rejection(s), the
effective date of the affirmance is deferred until conclusion of the
Appeal 2014-005529
Application 12/783,503

11
prosecution before the Examiner unless, as a mere incident to the limited
prosecution, the affirmed rejection is overcome.
If the Appellants elect prosecution before the Examiner and this does
not result in allowance of the application, abandonment, or a second appeal,
this case should be returned to the Patent Trial and Appeal Board for final
action on the affirmed rejection, including any timely request for rehearing
thereof.

Beschreibung
[0001] Die Erfindung betrifft eine Tabakportion, ein
Verfahren zum Herstellen von Tabakportionen sowie
ein dabei benutztes Zwischenprodukt und dessen
Herstellung.
Stand der Technik
[0002] Seim Selbstdrehen von Cigaretten wird in
der Regel Tabak, insbesondere Feinschnitt, in loser
Form einer Vorratspackung entnommen und von
Hand oder mit Hilfe eines kleinen Handgerats in ein
StUck Cigarettenpapier eingerollt, das abschlief5end
entlang einer Langsnaht verklebt werden muss. Da-
bei fallen immer wieder Tabakkrumel ab, und der
ganze Vorgang ist recht langwierig.
[0003] Aus der DE 195 31 061 A 1 ist ein System zur
Eigenherstellung von Cigaretten bekannt, bei dem
auf ein Umhullungsmaterial aus Cigarettenpapier
eine Tabakschicht aufgebracht ist, die im Querschnitt
wellenformig sein kann. Der Anwender muss dieses
Gebilde um die Langsachse aufrollen, so dass der
Tabak im lnnenraum zu liegen kommt. Eine einiger-
maf5en gleichmaf5ige Verteilung des Tabaks im auf-
gerollten Zustand ergibt sich nur bei der Ausgestal-
tung mit wellenformigen Querschnitt, die aber relativ
aufwendig ist.
[0004] Die EP 0 659 353 81 beschreibt ein System
zur Eigenherstellung eines Rauchartikels, das eine
leere Hulse, die an einem Ende von einem Filter ver-
schlossen ist, sowie mehrere Lagen von rekonstitu-
iertem Tabak unterschiedlicher Sorten enthalt. Der
Anwender rollt diese Lagen zu einem Zylinder und
schiebt sie in diesem Zustand in die leere Hulse. Die-
ses System ist auf die Verwendung mit in Folienform
vorliegendem rekonstituiertem Tabak eingeschrankt
und daher nicht kostengunstig und hinsichtlich der
Tabakauswahl wenig variabel.
[0005] Die DE-OS 1 809 983 offenbart ein Verfahren
zum industriellen Herstellen eines Tabakstrangs, bei
dem eine Schicht aus rekonstituiertem Tabak als
Bahnware mit Profilrollen gekrauselt, zu einem zylin-
drischen Bundel geformt und von einer Umhullung
umgeben wird.
[0006] Diese Schriften zeigen also Anwendungen,
bei denen Tabak nicht in loser Form zum Einsatz
kommt, sondern als rekonstituierter Tabak (Folienta-
bak) verfestigt oder auf einem Cigarettenpapier be-
festigt ist, was jedoch die erwahnten Nachteile mit
sich bringt.
[0007] In der DE 197 53 195A1 ist ein Filter fUr Ci-
garetten aus Zellulosevlies beschrieben, der nach ei-
nem Air-Laid-Verfahren hergestellt und spiralartig ge-
faltet wird.
2/5
Aufgabenstellung
[0008] Es ist Aufgabe der Erfindung, eine Moglich-
keit zu schaffen, die die Handhabung von portionier-
tem Tabak, z.B. bei der Selbstherstellung von Ciga-
retten, erleichtert.
[0009] Diese Aufgabe wird gelost durch eine Tabak-
portion mit den Merkmalen des Anspruchs 8, in der
ein Zwischenprodukt mit den Merkmalen des An-
spruchs 1 benutzt wird. Der Anspruch 14 betrifft ein
Verfahren zum Herstellen des Zwischenprodukts und
der Anspruch 17 ein Verfahren zum Herstellen von
Tabakportionen. Vorteilhafte Ausgestaltungen der Er-
findung ergeben sich aus den Unteranspruchen.
[001 O] Der Anspruch 1 betrifft einen Vliesstoff, der
Tabak enthalt.
[0011] Linter dem Begriff Vliesstoffe versteht man
textile Flachengebilde aus Faservliesen (Vliesen),
deren Zusammenhalt durch die den Fasern eigene
Haftung gegeben ist und/oder die durch mechani-
sche Verfahren oder auf chemischem Wege verfes-
tigt sind, siehe Ullmanns Enzyklopadie der techni-
schen Chemie, 4. Auflage, Band 23, Seite 729 ff.,
Verlag Chemie (1983). Vliese sind das Vorprodukt fUr
Vliesstoffe. Sie werden im Wesentlichen aus Fasern
gebildet, gegebenenfalls unter Beimischung anderer
faseriger Bestandteile unterschiedlicher Art und Fa-
serlange. Die Fasern konnen in unterschiedlichen
Langen vorliegen, in einem Bereich, der sich von we-
nige mm langen Fasern bis zu sehr langen Fasern er-
streckt.
[0012] Vliesstoffe werden also im Gegensatz zu Ge-
weben oder Maschenwaren unmittelbar aus Einzelfa-
sern gebildet. Der Begriff Vliesstoff impliziert keine
Angabe Ober die Dichte des Materials und entspre-
chend bedeutet das Verfestigen eines Vlieses zu ei-
nem Vliesstoff lediglich, dass die Fasern und gegebe-
nenfalls ubrigen Bestandteile des Vlieses in einen zu-
sammenhangenden, selbsttragenden Verbund ge-
bracht werden. Ein Vliesstoff kann daher eine relativ
geringe Dichte haben und auch relativ dick sein.
[0013] Bei der Vliesbildung werden die Bestandteile
des Vlieses in der gewunschten Anordnung und Ori-
entierung abgelegt, z.B. in mechanischer Weise auf
Krempeln. Danach wird das Vlies zu einem Vliesstoff
verfestigt. Wahrend sich in dem Spezialfall eines Fil-
zes die dabei verwendeten Tierhaare relativ leicht un-
tereinander verhaken und verschlingen (siehe Ull-
manns Enzyklopadie der technischen Chemie, 4.
Auflage, Band 11, Seite 577 ff., Verlag Chemie
(1976)), mussen die Bestandteile des Vlieses in der
Regel durch besondere Maf5nahmen verfestigt wer-
den, z.B. mittels mechanischer Verfahren oder durch
den Einsatz von Bindemitteln.
DE 103 46 649 A1 2005.05.12
[0014] Ein haufig benutztes mechanisches Verfah-
ren ist das Vernadeln, bei dem das Vlies in einer Na-
delmaschine von einerVielzahl von Nadeln durchsto-
f5en wird, die mit Widerhaken versehen sind und
beim Zuruckziehen die Fasern des Vlieses miteinan-
der verschlingen. Der dabei entstehende Vliesstoff
wird Nadelfilz genannt.
[0015] Die Erfindung beruht auf der Erkenntnis,
dass sich nicht nur die ublichen textilen Fasern wie
Wolle oder Baumwolle zu einem Vliesstoff verarbei-
ten lassen, sondern auch Tabak. Vorzugsweise be-
tragt der Tabakanteil des Vliesstoffes mindestens 50
Gew.-%; er kann bis zu 100 Gew.-% betragen. Fein-
schnitt ist besonders fUr die Fertigung eines Vliesstof-
fes geeignet, da er lange Fasern hat, die sich gut ver-
arbeiten lassen. Im Prinzip konnen jedoch alle Tabak-
teile verwendet werden, wobei faserige oder zu Fa-
sern aufbereitete Tabakbestandteile bevorzugt wer-
den.
[0016] Die Verarbeitung von Tabak zu einem Vlies-
stoff kann grundsatzlich auf herkommlichen Maschi-
nen erfolgen, wie sie in der Textiltechnik bekannt
sind.
[0017] So kann ein tabakenthaltendes Vlies mecha-
nisch auf einer Krempel gebildet werden.
[0018] In einer bevorzugten AusfUhrungsform wird
das Vlies durch Vernadeln zu einem Nadelfilz verfes-
tigt, vorzugsweise ohne Verwendung von Bindemit-
teln. Es ist aber auch denkbar, das Vlies unter Zusatz
von Bindemittel zu verfestigen, wobei als Bindemittel
z.B. Zucker, Starke, Starkeether, Guar Gum, modifi-
zierte Cellulose (z.B. Carboxymethylcellulose, Me-
thylcellulose und deren Derivate wie Methylhydroxy-
ethylcel I u lose, Ethyl hyd roxyethyl ce 11 u lose, Methyl hy-
d roxypropyl ce 11 u lose, Hyd roxyethylcel I u lose), Polyvi-
nylal kohol, Alginate, Alginate plus Calcium und Mi-
schungen dieser Substanzen zum Einsatz kommen
konnen. Die Bindemittel werden bevorzugt in wassri-
ger Losung eingesetzt. Die Konzentration der Binde-
mittel betragt vorzugsweise 0,5 Gew.-% bis 10
Gew.-%, insbesondere 3 Gew.-% bis 5 Gew.-%.
[0019] Der Vliesstoff hat vorzugsweise eine Dicke
im Bereich von 1 mm bis 15 mm, wobei ein Bereich
von 2 mm bis 8 mm besonders bevorzugt ist.
[0020] Die erfindungsgemaf5e Tabakportion weist
einen derartigen, tabakenthaltenden Vliesstoff auf.
Vorzugsweise ist dies ein StUck Vliesstoff, bei dem
die Gr615e der Querschnittsflache der Gr615e der
Querschnittsflache einer Cigarette entspricht und
vorzugsweise im Bereich von 25 mm2 bis 80 mm2
liegt. Dabei kann der Querschnitt des StUcks Vlies-
stoff unterschiedliche Formen haben. So kann er z.B.
flach sein, also langgestreckt rechteckig, so dass sich
das StUck Vliesstoff in die Form einer Cigarette rollen
3/5
lasst. Eine andere Moglichkeit ist eine gedrungen
rechteckige bis quadratische Form. Es ist auch denk-
bar, ein StUck Vliesstoff mit einem runden Quer-
schnitt bereitzustellen. Vorzugsweise entspricht die
Lange des StUcks Vliesstoff der Lange des Tabak-
strangs einer Cigarette oder der Lange des Aufnah-
meraums einer vorgefertigten Cigarettenhulse (siehe
unten), z.B. 69 mm wie bei einer Standard-Filterciga-
rette. Grundsatzlich ist es auch moglich, mehrere
StUcke Vliesstoff zu einer Tabakportion zusammen-
zufassen.
[0021] In der Tabakportion kann der Vliesstoff von
einer Umhullung umgeben sein. Ein Beispiel hierfur
ist eine Cigarette, in der der Vliesstoff als Tabak-
strang dient und die eine Umhullung aus Cigaretten-
papier und auf5erdem einen Filter hat.
[0022] In einer besonders bevorzugten AusfUh-
rungsform der Erfindung ist die Tabakportion zur Ver-
wendung beim Selbstverfertigen von Cigaretten
durch den Endverbraucher (z.B. Cigarettendrehen)
hergerichtet. Bei der Verwendung zum Cigaretten-
drehen werden in geeigneter Verpackung einzelne
Tabakportionen bereitgestellt, die vorzugsweise je-
weils aus einem VliesstoffstUck in Lange der vorge-
sehenen Tabakstranglange bestehen und die einen
Querschnitt haben, der z.B. quadratisch ist und in sei-
ner Gr615e der Querschnittsflache einer ublichen
selbstgedrehten Cigarette entspricht. Der Anwender
kann eine solche Tabakportion schnell und problem-
los in ein Cigarettenpapier eindrehen, z.B. von Hand
oder mit Hilfe eines Handgerats. Das langwierige
Festlegen der richtigen Tabakmenge entfallt, da die
Tabakportion durch das VliesstoffstUck vorgegeben
ist, und es entstehen keine lastigen Tabakkrumel, da
der Tabak in dem Vliesstoff gebunden ist. Wenn das
Cigarettenpapier von auf5en um das StUck Vliesstoff
gelegt wird, start z.B. ein quadratischer Querschnitt
des StUcks Vliesstoff nicht, da seine Langskanten
nachgeben und die Cigarette nach dem Zusammen-
kleben des Cigarettenpapiers somit eine mehr oder
weniger runde Querschnittsform erhalt. Vorzugswei-
se ist die Stopfdichte des Tabaks in dem StUck Vlies-
stoff bei der auf diese Weise selbstgedrehten Ciga-
rette so grof5 wie die Stopfdichte des Tabaks in einer
ublichen selbstgedrehten Cigarette.
[0023] Bei einer anderen vorteilhaften Verwendung
der Tabakportion ist die Tabakportion zur EinfUhrung
in eine vorgefertigte Cigarettenhulse hergerichtet.
Derartige Cigarettenhulsen konnen mit einem Filter
verse hen, aber auch filterlos sein. Im Stand der Tech-
nik gibt es Systeme, bei denen eine zum Einschieben
in eine Cigarettenhulse vorgesehene Tabakportion
herkommlichen losen Tabak enthalt, der von einer
aluminiumkaschierten Hulse umgeben ist. Bei Ver-
wendung einer Tabakportion, die vorzugsweise aus
einem StUck Vliesstoff in Lange des in die Cigaretten-
hulse passenden Tabakstrangs und mit an die Ciga-
DE 103 46 649 A1 2005.05.12
rettenhulse angepasstem Querschnitt besteht,
braucht keine der aluminiumkaschierten Hulse ver-
gleichbare Umhullung vorhanden zu sein, da der Ta-
bak in dem Vliesstoff gebunden ist. Dies erspart Kos-
ten und verringert den Abfall.
[0024] In einem Verfahren zum Herstellen von Ta-
bakportionen werden von einem Vliesstoff, der nach
einem der erlauterten Verfahren hergestellt warden
ist, StUcke abgetrennt, vorzugsweise durch Ab-
schneiden. Eine einzelne Tabakportion kann aus
mehreren StUcken Vliesstoff gebildet werden, wird
vorzugsweise aber aus einem einzigen StUck Vlies-
stoff gebildet.
AusfUhrungsbeispiel
[0025] Im Folgenden wird die Erfindung anhand von
AusfUhrungsbeispielen weiter erlautert.

Non-woven fabric containing tobacco, e.g. needled felt or
bonded non-woven made from fine-cut tobacco fibres, used as
tobacco portions for making self-rolled cigarettes
Seidel, Henning (Inventor). REEMTSMA H F & PH (Assignee). DE

Description
[0001] The invention relates to a tobacco portion, a method for the production of tobacco
and a used intermediate and its production.
State of the Art
[0002] When is usually removed Cigarette hand-rolling of tobacco, in particular A fine, in
loose form a storage package by hand or with the aid of a small hand-held device and rolled
into a piece of cigarette paper, the conclusion must be glued along a longitudinal seam. Here
[...] ab is repeated, and the whole operation is quite lengthy.
[0003] a system for making homemade Cigarette from DE 195 31,061 A1 is known, in
which a tobacco layer is applied to a wrapping material consisting of cigarette paper, the
sinuous in cross-section may be. The user must roll up this construct about the longitudinal
axis, so that the tobacco comes to lie in the interior space. A reasonably even distribution of
the tobacco in the rolled-up state occurs only if the shaping with wave-shaped cross-section,
but which is relatively expensive.
[0004] The 0,659,353 B1 describes a system for a smoking article self-production EP, the an
empty shell, the is closed at one end by a filter contains, as well as a plurality of layers of
reconstituted tobacco of different varieties. These layers into a cylinder and pushing rolls The
user in this state into the empty shell. This system is restricted to the use with in sheet form
and therefore not cost effective and as regards the reconstituted tobacco present tobacco
selection little variable.
[0005] The 1,809,983 discloses a method for the industrial production of a tobacco web DE-
OS, in which a layer of reconstituted tobacco with profile rollers crimped as web-type goods,
shaped and is surrounded by a casing to form a cylindrical bundle.
[0006] This writings show that is, applications, where tobacco not in loose form is used, but
as reconstituted tobacco is fixed (tobacco foil) solidified or on a A cigarette paper, what does,
however, introduce the mentioned have its disadvantages.
[0007] In DEcellulose fleece 197 53,195 A1 is described from a filter for cigarettes is
produced and by a folded spirally Air-laid method.
Tasks
[0008] The task of the invention is, to create a possibility, the handling [...] tobacco, e.g.
in which the self-production of cigarettes, facilitated.
[0009] This problem is solved by a tobacco portion having the features of claim 8, having
the features of claim 1 is used in the an intermediate. Entitlement 14 relates to a method for
producing the intermediate and the claim 17 a method for the production of tobacco.
Advantageous configurations of the invention result from the subordinate claims.
[0010] Entitlement 1 relates to a nonwoven fabric, the tobacco contains.
[0011] The term non-woven fabrics (nonwovens) textile fabrics understands from nonwoven
fabrics, their cohesion adhesion is given by the the fibers and/or by mechanical methods or
their own by chemical means are solidified, [...] Encyclopedia of technical chemistry see, .
support 4, band 23, side 729 et seq., Verlag Chemie (1983). The preliminary product for
nonwovens are nonwoven fabrics. You are formed essentially of fibers, with the optional
addition of other fibrous components of different kinds and fiber length. The fibers are present
in different lengths can, in a range, from a few mm long fibers extends up to very long fibers.
[0012] in contrast to woven fabrics or knitted fabrics are therefore formed directly
from non-woven fabrics individual fibers. The term No information concerning the density of
the material and, correspondingly, the non-woven fabric involves solidifying means of a non-
woven fabric into a nonwoven fabric only that the fibers and optionally other components of
the non-woven material into a coherent, self-supporting composite be brought. A nonwoven
fabric can also be relatively thick and therefore have a relatively low density.
[0013] In web formation in the desired arrangement and orientation of the non-woven
material are deposited the constituents, e.g. in mechanical manner on carding. Afterwards the
non-woven is consolidated into a nonwoven fabric. In the special case of a felt the used animal
hair While relatively easy to snag and intertwine one another ( [...] Encyclopedia see of
technical chemistry, 4. support, belt 11,577 et seq. side, Verlag chemistry (1976)), the
components must be solidified by special measures, as a rule, of the non-woven material, e.g.
by means of mechanical methods or by the use of binders.
[0014] A often used mechanical process is the needling, wherein the batt is pierced by a
plurality of needles in the needle machine, and when retracted are provided with barbs eat up
the fibres of the fabric together. The resulting nonwoven fabric is referred to as needle felt.
[0015] The invention is based on the recognition that it is not just the usual textile fibers
such as wool or cotton have processed into a nonwoven fabric, but also tobacco. Is at least
50% in weight of the nonwoven fabric tobacco portion the Preferably, ; it can amount to up to
100 wt- %. A fine is particularly suitable for the production of a nonwoven, since it has long
fibers, the process can be well. In principle may, however, be used all tobacco pieces, wherein
fibrous or tobacco constituents are preferably processed into fibers.
[0016] The processing of tobacco into a nonwoven fabric can be carried out on
conventional machines in principle, as they are well known in textile technology.
[0017] So a tobacco-containing non-woven fabric are formed on a carding machine can
mechanically.
[0018] the non-woven is consolidated by needling In a preferred embodiment to a
needled felt, preferably without the use of binders. But it is also conceivable, with the addition
of binder to solidify the web, wherein as binders e.g. sugar, starch, starch ether, guar gum,
modified cellulose (e.g. carboxymethyl cellulose, methyl cellulose and their derivatives, such
as methyl hydroxyethyl cellulose, ethylhydroxyethyl cellulose, methylhydroxypropyl cellulose,
hydroxyethyl cellulose), polyvinyl alcohol, alginates, alginates plus calcium and mixtures of
these substances can be used. The binder are preferably used in aqueous solution. 0.5 wt- %
to 10 The concentration of the binder is preferably 1% by weight, in particular 3 wt. - % to 5
wt. - %.
[0019] The nonwoven fabric preferably has a thickness in the range of 1 mm to 15 mm,
particularly 2 mm to 8 mm is preferably wherein a range of.
[0020] according to the invention has a tobacco portion such The, tobacco-containing
nonwoven fabric on. Preferably this is a piece of non-woven fabric, wherein the size of the
cross-sectional area of the size of the cross-sectional area and preferably in the range of 2
to 25 mm corresponds to a cigarette is 80 mm 2. It the cross-section can have different shapes
of the piece of non-woven fabric. So he can for example be flat that is, elongated rectangular,
so that the piece of non-woven fabric in the form of a cigarette is accompanied. Another
possibility is a compact rectangular to square shape. It is also conceivable, to provide a piece
of nonwoven fabric with a round cross-section. Preferably, the length corresponds to the
length of the tobacco web a cigarette or the length of the piece of non-woven fabric a
prefabricated [...] (see below) of the reception chamber, for example as at a standard filter
cigarette 69 mm. In principle it is also possible, more pieces of non-woven fabric to a tobacco
portion together.
[0021] In the tobacco portion of the nonwoven fabric can be surrounded by an envelope. An
example of this is a cigarette, the tobacco rod serves as an enclosure in which the non-woven
fabric consisting of cigarette paper and further comprising a filter and has.
[0022] In an especially preferred embodiment of the invention is for use in the tobacco
portion selfproduce of cigarettes (e.g. [...] ) adapted by the final consumer. When using [...]
are provided in suitable packaging individual portions for, the are preferably each comprise a
tobacco strand lengthpiece of fleece material in increase in the time and the have a cross-
section, the size of the cross-sectional area corresponds to a conventional hand-rolled for
example is square and in its cigarette. The user can quickly and easily in such a tobacco
portion edges rotate a A cigarette paper, e.g. by hand or with the aid of a hand-held device.
The lengthy setting the correct quantity of tobacco is omitted, because the tobacco portion
piece of fleece material is predetermined by the, , giving rise to no annoying [...], because the
tobacco is bound in the nonwoven fabric. If the cigarette paper is placed from the outside
around the piece of non-woven fabric, for example a square cross-section of the piece of non-
woven fabric not interfere with, since its longitudinal edges and the cigarette after the
adhering together of the give in [...] thus receives a more or less round cross-sectional shape.
Preferably, the maximum packing density in this way is the tobacco in said piece non-woven
fabric in which in a conventional hand-rolled cigarette as great as the maximum packing
density of the tobacco hand-rolled cigarette.
[0023] In another advantageous use of the tobacco portion is adapted for insertion into a
prefabricated [...] the tobacco portion. Such [...] can provided with a filter, but also be
filterless. There are systems in the prior art, where a loose tobacco contains [...] provided for
insertion into a conventional tobacco portion is surrounded by a sleeve aluminum-covered.
Using a tobacco portion, which preferably comprises a piece of non-woven fabric in length of
the in is a closely fitting cross-section and with the mating to the tobacco web [...][...], no
comparable enclosure to be present the aluminum-covered sleeve needs, because the tobacco
is bound in the nonwoven fabric. That saves costs and the waste reduced.
[0024] In a method of making portions of tobacco are separated from a non-woven material
has been prepared, the according to one the explained method, pieces, preferably by cutting.
A single tobacco portion can be formed from several pieces nonwoven fabric, but is preferably
formed from a single piece of non-woven fabric.
