Method and device for producing a reinforced socket on an extruded thermoplastic tube by radial extrusion of a thermoplastic material |
摘要 |
The present invention relates to a method and an apparatus for producing a reinforced socket on an extruded plastic tube made of thermoplastic material, preferably a corrugated tube, in which the tube is provided with end sockets at predetermined segment lengths. One end of the plastic tube or of a segment thereof is placed on a support mandrel and together with this support mandrel is rotated about its longitudinal axis. During the rotation, a layer of plastic is extruded onto a pre-formed socket region of the tube and/or onto the support mandrel, forming a reinforced socket formed on the tube.
