摘要: Apparatus is disclosed for making open-gusset bags from overlapping webs of thermoplastic material. A notch-perforator is provided along a side edge of the web for providing sets of notches and perforations or slits at spaced points along the web. V-shaped notches are applied to the gusset portion of the web and then the web is slit and welded transversely to divide the web into bags.
