ABSTRACT:
A method of manufacturing a door edge guard of the type particularly suitable for protection of the edge of an automobile door from paint chips. The method is an improvement over the technique of using separate manufacturing procedures to produce a plastic U-shaped inner channel (liner) configured to mate with a U-shaped metal outer channel. The method of the invention comprises the steps of roll-forming a metal element of an edge guard into a U-shaped channel element and bonding a plastic material to at least a portion of the inner surface area of the U-shaped metal element prior to completion of the roll-forming operation. The bonding may take place before roll-forming is begun.
