ABSTRACT:
A process for the production of a foam-backed article in which a covering is formed by sewing several parts together along joining seams and the outer side of the cover is laid onto a preliminary mold. A one-piece airtight film is positioned so that it overlies the whole of the covering and is then applied against the film and a peripheral edge portion of the film is sealed against the preliminary mold. The vacuum is applied to the interior of the preliminary mold to pull and bond the film to the inner side of the covering which is thereafter removed, turned inside out, and applied into a thermoforming mold in which the foam backing is formed.
