Abstract

1280629 Bag-making machines; seaming non-metallic sheet material. F J ROWELL 16 June 1971 [19 June 1970] 29867/70 Headings B5D and B5K A machine for making plastics bags by transversely sealing and severing lay-flat tubing, comprises feed-rollers 3a, 3b supplying two or more lay-flat tubes 1, 2 to pass between elements 4, 5 reciprocating vertically and horizontally and carrying heat-sealing and crimping jaws 10, 11 or more which are independently operable by pistons and cylinders 13, 14 in response to control marks 17, 18 on the tubes to produce bags of different lengths simultaneously. Jaws 10 are separated by a knife-blade 20 in slot 19. Hydraulic cylinder 4a, 5a provides the vertical shift of elements 4, 5, and eccentric journal 8 engages slide-way 7 to provide the horizontal shift. Marks 18, 17 are sensed by photo-electric devices 16, 15.
