ABSTRACT:
The method of this disclosure permits the application of a foam layer, in fluid form, to a relatively porous substrate and the formation of a contoured foam laminate using a relatively rigid foam. The method includes heating the substrate prior to application of the fluid foam and forming the laminate in a die prior to completion of foaming. The laminate includes a flexible substrate, preferably a polyurethane foam layer and a lattice skrim located between the substrate and the exposed surface of the foam layer.
