Abstract
Draw tape bags are provided on a roll, preferably folded longitudinally with the hems containing the draw tapes extending beyond the body of the bags for smooth rolling. The bags are side sealed with perforations between bags for separation of the bags, and the hems containing the draw tapes are side welded so that the hemmed areas are substantially separated. The bag machine for making side sealed bags includes a side welding unit in line with the sealing unit so the sealing and perforating, and welding, are accomplished in one step. The side welding knife has a large radius and high temperature to effect a weld in the multiple layers and the thick draw tape.
