ABSTRACT:
A substrate is initially moulded from a cross-linked polymeric material reinforced with glass fibres, the substrate is subsequently placed in a die in which a facing layer is first moulded, and on that layer are injected the ingredients for a foam padding material which adhere the substrate to the facing layer. The facing layer is desirably polyurethane, although use can be made of flexible acrylic, polyvinylchloride, and some other polymeric materials.
