Abstract

1,031,040. Perforating thermoplastic sheets. KENDALL CO. Jan. 19, 1965 [Dec. 30, 1963], No. 51201/63. Addition to 851,473. Headings B5A and B5B. The apparatus defined in Claims 8 to 10 of the parent Specification (which apparatus comprises a rotatable hollow cylinder of heat conductive material having a perforated peripheral wall, a part of the circumference of which is embraced by a travelling web of thermoplastic organic polymeric thin sheet material (such as a film), means for directing a stream of a hot gas on the exposed surface of the sheet on the cylinder, and means for cooling the cylinder) is modified in that the cylinder drum is imporforate, that its peripheral surface is covered by a thin perforated sleeve of heat conductive material and that there is provided a burner for directing a flame on to a portion of the travelling web of film sheet material at any moment of time embracing a portion of the circumference of the sleeve and that means are provided for cooling the drum at a locality remote from the flame. The cylinder may be mounted for rotation about a horizontal axis, the burner being situated above the drum and extending longitudinally thereof and the cooling means being situated below the drum. The cooling means may be constituted by a pipe extending longitudinally of the drum and having holes through which cooling air may be directed on to the drum.
