Beschreibung
Zusammenfassung:	Process for sheathing rotational-symmetrical, metallic objects (1) with firmly adherent plastics by extrusion, characterised in that, prior to the sheathing plastic extrusion, the metallic object (1) is provided with a heat-curing coupling agent, which is baked immediately upstream of the extruder (6), and the still hot metallic object (1) with the baked coupling agent is guided through the extruder (6) for sheathing with plastic.
