The molded and cut piece is removed while the skin is still held by the edge portions and the skin is then removed. The mold is returned to its initial position immediately at the end of the thermoforming operation. The skin that remains after the thermoforming operation is cut up and ground and the resulting granular material is recycled to the extruder which produces the strip. This granular material may be mixed with non-recycled granular material before it is recycled to the extruder.
