Abstract

981,736. Making bags. SEISAN NIHON SHA KABUSHIKI KAISHA Feb. 28, 1961 [April 11, 1960 (2); June 3, 1960], No. 7372 /61. Heading A4G. A synthetic resin pouch is formed from a continuous tube 6, Fig 1, extruded from a die B and having one or two pairs of integral complimentary internal closure elements 9, 10, Fig. 4, the tube then passing through guides 12 and rollers 11, 17, 18 to a guide device D whereby the tube is flattened with the closure elements interengaging. The guide device comprises a frame 23, Fig. 8, supporting a slotted bar 25 and felt pad 37 through which the tube passes and a wedge member 19 inside the tube adjustably spring tensioned in width to accomodate the tube width and formed with vertical grooves to receive the closure elements and bring them to inter-engaging position so that, as the tube passes through a further slotted bar 74, the closure elements engage. The wedge 19 is positioned magnetically or by its weight resting on the tube and pad 37. The flattened tube or roll E is then led through rollers 202 and belts 203, Fig. 18 to a conveyer belt 239 where a heated knife 222 and cooperating cooled pressing elements 224 are operated to cut and seal the tube into pouches by a connection with bar 211 operated by cranks 212-214 moving in relation with rollers 202. A further shoe 233 compresses the welds. If two opposed pairs of closure elements 9, 10 are formed in the tube, two pouches at a time may be formed. Specification 981,737 is referred to.
