ABSTRACT:
Method and apparatus for processing extruded thermoplastic material for use in siding by advancing the extrudate from the die member through a series of baths which size and shape the extrudate. The process sizes and cools the extrudate, and, thence, heat treats the extrudate followed by a final quenching of the extrudate in its final shape and size.
