ABSTRACT:
A method of molding cloth. A special multi-layer cloth is drawn into a mold by means of a vacuum between the cloth and the mold. The cloth includes a fabric layer, stitches of the fabric having never been thermally set, a polyurethane foam layer and a polyvinyl chloride film layer bonded together. After the cloth has conformed to the contours of the mold, the shape of the cloth is fixed to maintain the mold contours. To this end, the cloth may be heated, or polyurethane foam may be poured into the mold and allowed to expand.
