APPARATUS FOR THE MANUFACTURE OF HOT-SEAL GARMENT BAGS Abstract An apparatus and method for the mass manufacture of garment bags includes the steps of first defining a central longitudinal strip in a cover plastic sheet and heat joining a zipper structure to the so-formed pair of large bands thereby forming a cover sheet for the garment bag. The zipper structure includes a series of successive and integral zippers each comprising interlocking longitudinal inner edges with locking members disposed near the front and rear ends of each zipper section. A handle piece being provided between the front and rear locking members to engage and disengage the inner longitudinal edges of each zipper section. The handle piece is limited in its travel by the locking members. An opening is being defined in each zipper section intermediate the front locking member and the front end edge thereof. Second, a second plastic sheet is positioned under the cover sheet and heat sealed thereto at the side longitudinal edges thereof with excess plastic being removed by cutting from these side edges. Then, the transverse end edges of the cover sheet and of the second plastic sheet are heat joined between the front end of a first garment bag and the rear end of a successive garment bag. Finally, these bonded transverse end edges are cut along their axis to form a bonded front edge of the first garment bag and a bonded rear edge of the second garment bag which is now separated from the first garment bag. A device is provided to stack the completed distinct garment bags. Printing and drying apparatuses may he provided to decorate the cover sheet of the plastic garment bag.
