An apparatus for simultaneously pulling and twisting a cylindrical extrudate as a whole into a helical configuration, that is, a cylindrical configuration that, as a whole, has longitudinal and circumferential vector components. The apparatus is adapted to act on a solidified extrudate by causing it to be pulled downstream in the direction of its longitudinal axis while simultaneously being rotated about its axis. A circumferential twisting and a downstream pulling are simultaneously applied to a cooled and solidified extrudate. This is accomplished with a single piece of apparatus as shown. Thus, by twisting the solidified extrudate downstream both a circumferential and an axial component are imparted to the solidified extrudate. This, in turn, imparts a longitudinal and a circumferential movement to the molten extrudate as it emerges from an extruder die before it is fully solidified. The thus twisted molten extrudate is the cooled and solidified in its twisted condition.
