Abstract

Apparatus adapted to introduce biaxial orientation in a tubular member, of thermoplastic synthetic polymer material, characterized in that it comprises a mandrel of rigid construction, parked between an annular extrusion die orifice and means for removing the material, said mandrel being provided, (a) externally of a longitudinally tapered advancing end, of continuous curvature in cross section, and (b) internally of a series of temperature control zones, said zones including a heating zone located inside said tapered leading end , with which a temperature higher than the glass transition temperature of said thermoplastic material is established in said member, and a cooling zone located behind said heating zone, in which a lower temperature is established in said member. of glass transition of said thermoplastic material.
