ABSTRACT:
Essentially continuous thermoplastic resin molding of complex decorative relief is produced by continuously extruding molten resin into a rotating forming wheel and cooling and removing the molded resin from the wheel. A doctor wheel cooperates with the forming wheel to provide a flat surface to which a pressure-sensitive adhesive layer may be applied for bonding the resin molding to an intended substrate.
