Abstract

<PICT:0851473/IV(a)/1> Sheets (including films) of flexible, thermoplastic organic polymeric material are perforated by melting and perforating the material of the sheet at selected localized areas of the sheet by subjecting the sheet to the action of a hot fluid while simultaneously cooling other areas of the sheet to prevent these other areas from melting. As shown, a reel 51 of a continuous film is fed, as indicated at 52, over a hollow rotating metal cylinder 53, the peripheral surface of which is provided with perforations of the desired dimension and pattern, and the film then passes to a take-up roll 54. Opposite the cylinder 53 there is provided means for directing a jet of heated air, in the form of a thin band parallel with the axis of rotation of the cylinder and having the width of the area of the film to be perforated, on to the surface of the film passing over the cylinder. The jet is heated by the gas burner 56 and is discharged from the horizontal slit-shaped orifice 57 under pressure supplied through the pipe 58. A jet of cooling air of similar shape to the jet of hot air is directed against the rear surface of the cylinder 53 from the nozzle 60. Jet temperatures as low as the melting point of the sheet material may be used, but jet temperatures of 200-875 DEG C. with film speeds of 4-33 yards per minute are preferred. The perforations in the metal cylinder 53 may be circular and have diameters of 2 mils to 1/4 inch. Each perforation is encircled by an annular bead which serves to reinforce the edge of the perforation.
