Abstract
1523036 Making bags; seaming IMPERIAL CHEMICAL INDUSTRIES Ltd (Canadian Industries Ltd) 15 March 1977 [23 March 1976] 11632/76 Headings B5D and B5K A method of producing bags from a plastics web 1 comprises intermittently advancing the web 1 by increments of one bag length, folding- in side margins of the web to form overlapping panels and heat-sealing said overlapping panels together by forming two partially overlapping longitudinal seals 5, 6 for each bag, the seal 6 of each bag being formed simultaneously with the seal 5 of the adjacent following bag. This method permits the production of bags of different lengths merely by changing the amount by which the web is advanced during each incremental movement, with consequential variations of the amount of overlap of the seals 5, 6.
