ABSTRACT:
The present invention is directed to the manufacture of plastic tubing exemplified by corrugated plastic tile and parts related thereto, in which molds for shaping an extrudable plastic material are caused to shuttle linearly forwardly and rearwardly with respect to an extruding source of said plastic material. Sequentially related to linear mold movement is opening and closing mold action, which is correlated to the discharge of plastic material from the extruding source thereof. Provision is also made herein during the course of linear mold movement for parking one or more predetermined molds at a location spaced from the extruding source.
