ABSTRACT:
Extrusion method and apparatus for producing a molding strip wherein an outer polyurethane plastic layer is interbonded at its inner surface to the outer surface of a flexible PVC plastic body is disclosed. A single die is utilized to produce the molding strip. The polyurethane plastic layer and the flexible PVC plastic body are interbonded while in a molten state within a bonding chamber of the die so that the polyurethane plastic layer does not separate from the PVC plastic body during use of the molding strip. The polyurethane plastic layer is interbonded with the PVC plastic body without totally encapsulating the PVC plastic body so that the molding strip can be adhesively secured to a side body panel at the PVC plastic body. The outer surface of the polyurethane plastic layer can be painted to match the color of the side body panel. Preferably, a reinforcement strip is embedded in the PVC plastic body within the bonding chamber to give the molding strip additional strength.
