Abstract
Abstract Method of molding a film-faced product. The method involves placing a body or mass of compressible material such as a body or mass of mineral fibers impregnated with a binder in a contoured molding matrix with a self-supporting resinous film disposed on a major surface of the body or mass, applying reduced pressure to force the film into intimate contiguous engagement with a contoured matrix, compressing the body or mass of material in the molding facility, and setting the binder in the molded product. The film facing of the product is adhered to the compressed mass or body and shaped to a high fidelity of configuration of the molding matrix.
