ABSTRACT:
The present invention provides a unique and rapid method of producing a laminated foam article having permanent, pliable, decorative embossed lines or patterns which produce a relief-like article such as an embossed seat cushion or the like. In one aspect, the present invention comprises the steps of coating the surface of a foam layer with an adhesive, placing a sheet or layer of cover material on the adhesive-coated foam layer surface, compressing the covered foam layer with a die having heated projection such that regions of the foam layer adjacent the hot die melt to form embossed lines which are permanent yet pliable. Since the embossed lines are actually collapsed, melted regions of the foam layer, thick, high density foam layers may be embossed using the present invention. In another aspect, a trilaminate structure is fabricated by additionally bonding a backing layer to the side of said foam layer opposite that to which said cover material is bonded. In one embodiment, the adhesive is cured during the embossing step by the heat from a heated platen and press.
