Abstract

1353078 Jointing; making hollow-ware AMERICAN CAN CO 17 Aug 1971 [20 Jan 1971] 38645/71 Headings B3A B3J and B3V [Also in Division B5] The edge E of a moving web 10 is wrapped with a thermoplastic adhesive strip by extruding a ribbon 20 of thermoplastic material on to and along the edge E of the web 10 therebeneath to dispose a portion of the ribbon in overhanging relation to the web edge, directing a flow of heated gas at the ribbon overhang portion to maintain it in softened condition and wrap it around the edge of the web to engage the undersurface thereof, and pressing the wrapped ribbon smoothly and tightly against the web. As shown, the web 10 of metallic or fibreboard container body stock is fed from a roll 12 past a preheater 14 to heat one longitudinal marginal edge E thereof. An extruder head 16 supplies a flat thermoplastic ribbon 20 to an applicator wheel 18 which is spring-biased to press the ribbon 20 on to the edge E. A photo-electric detecting and control system (not shown) may be used to align the ribbon 20 with the edge E. Nozzles 22, 24, 26 connected to a hot gas supply 28 progressively deflect the ribbon overhang downwardly over the edge E and under the web to engage the undersurface thereof. The nozzles 22, 24, 26 may be replaced by a helically perforated manifold. Rolls 30 firmly press the ribbon against the web. The ribbon 20 may be of polyethylene or a polyvinyl chloride resin or a copolymer thereof. The thermoplastic ribbon may provide adhesive bonding means for a container lap seam scan, Fig. 4 (not shown).
