It has been stated that a court should not sua sponte convert a petition to open a judgment into a petition to strike a judgment. See Grant Bldg. Co. v. Ivanciw, 266 Pa. Super. 395, 404 A.2d 1348 (1979); DeFeo v. Mac Intyre, 265 Pa. Super. 95, 401 A.2d 818 (1979); Baederwood Shopping Center v. St. George Co., 262 Pa. Super. 55, 396 A.2d 642 (1978); Melnick v.Hamilton, 87 Pa. Super. 575 (1926). Cf. Roselon Industries, Inc.v. Associated Knitting Mills, 221 Pa. Super. 8, 289 A.2d 239 (1972) (while grounds would support a petition to strike the judgment, the petition only requested that the judgment be opened; an order opening judgment will not be transformed into an order striking judgment).
