ABSTRACT:
A method of manufacturing a composite frame for a side gusset of a bag. The composite frame has a peripheral raised region and a depressed central region. The composite frame is made up of a moldable substrate, e.g. ethyl vinyl acetate foam, an outer layer of wear-resistant material, e.g., high-denier nylon, or poly
ylon combination, and, preferably, an inner adherent layer, e.g., the loop half of a hook-and-loop fabric. During the manufacturing process, a flat sheet of substrate is covered on one side by the wear-resistant material and, preferably, on the other side by the adherent layer. Incisions are cut through a central region of the substrate-adhered materials composite. The composite is then molded to provide the peripheral raised region and the depressed central region, with the raised surface being covered by the wear-resistant material.
