Abstract
In the method for producing an electric cable having stress relief, high-tensile stress-relieving members (28, 23) inside the injection head (10) of an extrusion machine are inserted into the still viscous cable sheath (14) in such a way that each stress-relieving member (23) is entirely surrounded by sheath material and is provided with a corrugation after leaving the extruder. The method permits the corrugation of the stress-relieving members (23) to be produced independently of the type of sheath material. The corrugation of the stress-relieving members (23) is brought about by selecting the speed of the sheath material in the injection head (10) of the extruder and the speed of the stress-relieving members embedded in said material to be higher than the speed of the cable core (13). As a result, after leaving the extruder the cable sheath (14) experiences strand widening which causes the corrugation of the stress-relieving members (23). <IMAGE>
