Patent ID: 8491744

Claim:
A method for the production of a strand-shaped part, comprising extruding a hollow profile from metal at an extrusion point in a direction of extrusion, the hollow profile extending away from the extrusion point and along the direction of extrusion, allowing the extruded metallic hollow profile to cool and extruding a one- or multi-layered plastic strand into said extruded metallic hollow profile prior to or after the cooling of said profile, causing said plastic strand to pass a dispensing tool of an extruder, the dispensing tool including a duct for transmission of the plastic strand to a discharge opening of the dispensing tool, wherein the dispensing tool is configured to conduct heat from the extruded metallic hollow profile and into the plastic strand when the dispensing tool is inserted into said metallic hollow profile and is exposed to the heat of said extruded metallic hollow profile, the discharge opening arranged downstream from the extrusion point along the direction of extrusion, and within a region of said metallic hollow profile, said profile having been cooled relative to a temperature of said profile during extrusion.
