ABSTRACT:
Sections successively severed from a double layer web of synthetic thermoplastic film, e.g., flattened tube stock, as produced are each stacked and welded to a precedingly stacked section near one edge of a tear off pat or hanger portion to which a bag portion of the section is attached; forming ultimately a pad of bag sections, wherein each section includes either a completed bag or a partially completed bag, in the latter case with final bag producing operations carried out simultaneously for all bags already welded together in a pad structure.
