Abstract

Appts. for producing plastic tubes with a screw threaded exterior and interior, which is placed at the exit of a die extruding a normal plastic tube, is characterised by the tube leaving the extrusion die passing through a rotating die whose orifice has groove in the form of helical threads with a definite pitch, this die being rotated at a velocity depending on the exit velocity of the tube from the extrusion die. The tube receives a lubricating pdt. over all its periphery, and is subjected to strong suction which forces it against the internal face of the orifice of the die, so that screw threaded grooves are formed before the tube is cooled. The tubes can be produced at high speed, and can have a screw thread with a high pitch.
