ABSTRACT:
An improved method for manufacturing a laminate wherein the edges of a deformable surface layer, such as cloth or carpet, are folded under and releasably secured to the undersurface of the deformable surface layer. The deformable surface layer is then placed into a mold unit and the securement between the folded edge and the undersurface of the deformable surface layer is released either prior to or during the injection of a plastic material for forming a plastic support layer. The method produces a laminate including a deformable surface layer having edges which are folded under and totally bonded to the plastic support layer. The bonded edges improve the securement between the deformable surface layer and the plastic support layer and give the laminate a "finished" appearance without tacks or staples.
