Abstract

Bags are made from a continuous web of flexible folded material with a double fold to form a pleat (9). The folded web is then spot welded (21) along transverse lines at a distance from each other equal to the width of a finished bag. Cut-outs of alternate semicircular (12) and rectangular form (13) are stamped out along the pleated edges (8). Tapes (17), made of plastics are threaded longitudinally through each fold of the pleat. The tapes are then cut at each semicircular cut out, and the ends of each parallel pair of tapes are welded together. The folded strip is then transported to the next mfg. stage.
