ABSTRACT:
Draw tape bags are made with folding surfaces which decrease in width to the final bag height. One edge of each side of a moving web of film is tucked onto a side of a surface to produce a hem in each edge of the moving web. Rollers, which are canted with respect to the direction of movement of the web, pull the hem of the film tight against the surface to insure that the web is at the final bag length when the web leaves the surfaces.
