ABSTRACT:
A laminate is prepared, which comprises a base layer of a fibrous material mixed with a synthetic resin and its cross linking agent, a cover layer of unvulcanized rubber and an intermediate layer of thermoplastic resin. The laminate is shaped into a desired shape by the application of heat and pressure at such an elevated temperature as to cause the cross linking reaction of the synthetic resin in the base layer, the vulcanization reaction in the cover layer and a change of the thermoplastic resin into a soft and adhesive condition to take place simultaneously.
