Abstract

Improvements introduced in the object of the main patent no. 358,494, filed on september 25, 1968, by: procedure for manufacturing molded articles, composed of a plastic foam material, which includes introducing into the cavity of a mold a liquid mixture of foam-forming ingredients and allowing said mixture to expand to fill said cavity, a laminate consisting of a layer of flexible cellular material, which extends against the surface, interposed between at least a part of the surface of the cavity and the liquid mixture. Of the cavity, and by an impermeable layer of extensible non-cellular material joined to said layer that is in contact with the foam-forming mixture, characterized in that low or high-modulus polyurethane foam is used as the layer of flexible cellular material.
