Abstract (en)
[origin: WO9748545A1] A process is disclosed for shaping socket ends (2) on plastic pipes (1) from hot-deformable plastics, in particular polyolefines or PVC. An area at the end of the pipe (1) having more or less the length of the socket is heated in a heating station up to or above its shaping temperature, is shaped in this state into a socket (2) by means of a socket-shaping tool (5) introduced into the pipe end (3) and is cooled down to a temperature lower than its hot-shaping temperature before and/or after the socket-shaping tool (5) is removed. Clamping devices (13, 14) which engage the pipe wall from inside and outside while enabling the socket-shaping tool to be introduced into the pipe retain the pipe (1) by the outer end of the socket area (2) to allow the socket-shaping tool (5) to be introduced into the pipe, and so the socket area is drawn and not pushed over the socket-shaping tool (5). A device for carrying out this process is also disclosed.
