Abstract

A single drawing apparatus 8 is used for continuous manufacture by extrusion of a pipe with screw thread. The said apparatus comprises two gripping devices 26, supported so that they can rotate about the axis of the tubular fabrication, which emerges from the nozzle, in supports 17 displaceably mounted parallel with the said axis on a frame 15. A motor 25, by way of two couplings, controls the displacement in the drawing direction of at least one of the supports 17. This displacement is accompanied by rotation of the gripping device 26 mounted on the relevant support through a chain of movement comprising gears 18 and a rack 19 connected to the frame 15. The return of the supports 17 is achieved by actuators 30. The tubular fabrication is thus moved continuously during drawing and rotation. <IMAGE>
