摘要 |
The invention relates to a method and device for producing a reinforced socket on an extruded plastic tube made of thermoplastic material, preferably on a corrugated tube. According to the invention, the ends of the tube are provided with sockets located at predetermined section lengths. One end of the plastic tube or a section thereof is slid onto a supporting mandrel and, together with the supporting mandrel, is rotated about its longitudinal axis.
