Claims20
A process for forming a smooth contoured laminated panel from layers of compressible polyurethane foam, fiber glass, scrim and remay comprising,
- supplying a mold having an upper part and a lower part, said parts including facing substantially mirror image, curved surfaces,
- assembling on the curved surface of said mold lower part in sequence:
- (a) a first layer of adhesive impregnated scrim,
- (b) a first layer of open celled compressible polyurethane foam, said first polyurethane layer being impregnated with an adhesive in an amount to fill the open cells and make said polyurethane layer incompressible when heated to a curing temperature,
- (c) a first layer of adhesive impregnated fiber glass,
- (d) a second layer of open celled polyurethane foam,
- (e) an adhesive impregnated remay, and
- (f) a decorative layer,
- bringing the curved surfaces of the two mold parts together to cause the assembled layers to conform to the facing mold surfaces,
- heating the molds to cure the adhesive impregnating the layers, and
- retracting the molds and removing the formed panel from the lower mold part.
