Abstract

1500365 Perforating plastics sheet UNION CARBIDE CORP 12 Feb 1975 [26 Feb 1974] 5873/75 Heading B5A A plastics sheet 11 has a hole 39 formed therein, the perimeter of which is formed by a continuous bead 43 of melted and rehardened plastics, the thickness of which is diminished at one point 43a to facilitate tearing i.e. the sheet from a wicket-held stack. The sheet is clamped between templates 13, 15 having apertures 17, 21 corresponding to the shape of the desired hole and subjected to a stream of hot gas from means 25, the stream axis being offset from the axis of the apertures. A plate 41 redirects the gas stream, which is heated by an electric element 27 in a tubular housing 25, upwardly. The perforated sheet may provide a wall of a packaging bag.
