AN EXTRUSION SHAPING METHOD Abstract of the Disclosure A method of extruding a profiled strip of polymeric material off the extrusion die of a plastic extruder and immediately thereafter compression forming a predetermined section of the profiled strip into a predetermined shape when temperature of the polymeric material is sufficiently high to allow plastic flow in the profiled strip. The method including the steps of first extruding a profiled strip of polymeric material through the extrusion die and compression molding a predetermined section of the profiled strip into a predetermined shape at a close proximity from the extrusion die with a set of compression molding dies capable of traveling with the profiled strip at substantially the same speed for a sufficient length of time to permanently set the predetermined shape, disengaging the compression molding dies from the profiled strip at a predetermined distance from the extrusion die; cooling the profiled strip having the compression molded predetermined shape in a suitable cooling fluid such that the predetermined shape is permanently maintained, and then trimming the extruded profiled strip into discontinuous pieces each having the compression molded predetermined shape.
