P-301 EXTRUSION METHOD AND APPARATUS AND PART PRODUCED THEREBY ABSTRACT Extrusion method and apparatus and part produced by the method and apparatus, such as a molding strip which includes a decorative Mylar plastic strip located between a pair of inter- bonded plastic layers. The top plastic layer or top coat is clear so that the decorative strip can be seen therethrough. A single die is utilized to produce the molding strip. The plastic layers are both preferably flexible PVC plastic which are interbonded by interfusion between adjacent surfaces while in a molten state within a bonding chamber of the die so that the plastic layers do not separate during use of the molding strip. The top coat is interbonded with the other plastic layer or body without requiring the clear plastic to totally encapsulate the resulting molding strip. Also, preferably, a reinforcement wire is embedded in the plastic body within the bonding chamber to give the molding strip additional strength.
