Abstract

A method for three-dimensionally shaping cover materials such as woven or knitted fabrics, vinyl, leather, and the like is performed by providing a cover material (18) and a layer of foamable liquid reaction mixture such as polyurethane which changes from liquid to a viscous state (16') at the beginning of the gas generating reaction, compressing the combined cover material and the foamed layer in a mold (21,22) having surface configurations corresponding to desired final three-dimensional shapes with the compression being performed when the foam layer has substantially completed rising, but before substantial curing thereof takes place, and then allowing the foamed layer bonded to the cover material to proceed in curing reaction. The three-dimensional cover material shaping is performed by this method without external heat or high pressure so that the cover material can retain its original appearance and high quality. By changing locally the spacings between mold halves (21,22), the resultant foam layer bonded to the cover material can be provided with portions having different local thicknesses and hardnesses.
