ABSTRACT:
In the SZ twisting of conductors of electrical cables followed by extrusion of a plastic sheath in the same operation, an untwisting of the reversal points of the twist direction in the area of the cooling section of the extruder is prevented by guiding the extruded sheath immediately behind the extruder in such a manner as to be secured against torsion.
