ABSTRACT:
A method of and apparatus for making printed gusset bags from tubular bag material, which may be extruded film plastic with integral interlocking fastener profiles along the edges of panels of the material which have been collapsed into face-to-face relation, and in which each of the panels will provide a succession of separate finished bags, comprising the step of and means for imprinting on each of the panels indicia on bag wall areas and on a gusset area intermediate the wall areas, the step of and means for manipulating the imprinted bag material from the originally collapsed condition to fold the wall areas of each of the panels together into face-to-face relation and to infold the gusset area of each of said panels into position between the folded bag wall areas of each of the panels, and the step of and means for separating the gusseted panels into individual gusset bags. When filled, the bags will present to view not only the indicia on the bag walls, but also the indicia on the expanded gusset area of each of the bags.
