ABSTRACT:
An apparatus for the manufacture of corrugated tubing of thermoplastic including a shaping path adjoining the head of an extruder, composed of a guide arranged in a frame structure, along which guide mold halves closed together in pairs as annular molds are advanced in close succession, said mold halves being provided on a lower side thereof with racks, at least one drive pinion arranged in the initial part of the shaping path for meshing with the racks of the mold halves as the same are pushed along the path, and an outlet, following the shaping path, in which the mold halves are separated from one another and are transferred to mutually separate return paths, on which they are shunted back by a conveyor to the inlet. In order to ensure introduction of the mold halves free of bumping at the inlet and a corresponding impact-free withdrawal of the mold halves at the outlet of the shaping path, the conveyor includes sequentially arranged, driven pinions adapted to come into mesh with the racks on the mold halves. The transverse conveying of the mold halves between the outlet and the inlet is performed by a pinion driven in a transversely movable manner.
