Abstract
987,633. Making cartons. LIQUID PACKAGING Ltd., and T. N. GAUNT. May 16, 1963 [Feb. 27, 1962], No. 7611/62. Heading B5D. [Also in Division B8] A paper board blank coated on one side with thermoplastic resin is formed into a tube with rectangular cross-section, placed on a former (Fig. 2) and its base folded as in Fig. 4; the flange 46 is then gripped first by heated jaws 42, 44 and then by cold jaws for heat-sealing; this flange is then folded on to the base with the coated side of the extension 40 towards the base and is secured thereto by pressure of a heated platen 48 (Fig. 5) and then a cold platen. The platens 48 preferably extend across the entire base to consolidate the whole base. The upper face of the former may be recessed to varying depths to accommodate the different thicknesses of the carton base or may be of resilient material, and the platen 48 is flat. Prior to folding the base, some or all of the parts forming the bellows folds 26, 28 and of these parts brought together in the final folding may be coated with a heat sealing or liquid adhesive such as polyvinyl acetate. The longitudinal seam necessary to form the blank into a tube is made from a strip 12 (Fig. 2) which extends from one side of the blank, which is folded in half longitudinally, coated side outwards, the two halves glued together, and the strip heat-sealed to the opposite boundary of the blank.
