Abstract: A process for forming, at the end of a pipe fabricated from a synthetic resin material, a socket having external ribs, beads, projections, or the like, extending in cross-sectional planes or helically, and apparatus for implementing the novel process, wherein the process contemplates the insertion of a temperaturecontrolled mandrel in the end of an initially-heated pipe, simultaneously imparting a rotary motion to the mandrel as it is axially advanced and, upon cooling of the pipe end, withdrawal of the mandrel with further rotary motion thereof.

Abstract: An apparatus for the extrusion of hollow articles of thermoplastic synthetic resin includes an extruded tool and a sizing device adjacent the extruding tool where the hollow article is drawn therefrom. The sizing device has a minor conicity so that the outlet opening in the sizing device is smaller than the inlet opening so that the shrinkage of the dimensions of the article is compensated for. A cooling device may be inserted within a hollow chamber of the article and in addition be externally coupled to the surface of the extruded article as it is drawn through the sizing device.
