Molding strip having a curvilinear surface and a method for making same from laminar sheet material

Abstract

The present invention is directed not only to a method for processing composite sheet material comprising a substrate to one flat surface of which a facing has been laminated but also to the resulting article of manufacture. The process permits the facing material to be shaped to a predetermined, curvilinear configuration. This result may be accomplished by incising a groove in that surface of the substrate opposite the surface thereof to which the facing is laminated so as to provide a freeform span of the facing. Adhesive is applied to selected portions of the substrate, and a predetermined charge of foam forming reactants are deposited along the groove. Thereupon the freeform span is bent to the desired configuration and, if required, so maintained while the foam forms and the adhesive sets.
