Patent DE-4003735-A1 (DE)
Inventor: BAUMGARTEN WILFRIED DIPL ING
IPC: H01B13/14
Filed: 1990-02-08
Abstract: The invention relates to the covering of a cable, including a twisted electrical cable comprising a plurality of conductors, the said covering having one or more layers, as well as vulcanisation and crosslinking of the same, in which the twisted cable (2) is passed through an extrusion apparatus (15) applying the covering layer, and in which the covered cable is subsequently passed through a vulcanising or crosslinking apparatus (17) and is at the same time rotated constantly about its axis by allowing a rotating apparatus (19) to act on the cable after the vulcanising and crosslinking apparatus. It is the object of the present invention to create a way of providing cables with a thick-walled covering by extrudate applied in one operation, with continuous application, in which the cable to be covered remains satisfactorily twisted. The invention consists in that, prior to covering, the twisting is loosened by deflecting the cable and the rotational movement imparted to the cable after the vulcanising or crosslinking apparatus allows the cable to pass through the extrusion apparatus (15) and the deflecting apparatuses (9, 11, 12) freely as far as possible up to or ahead of the unwinding point (3). The apparatus according to the invention is distinguished by the fact that a braking apparatus (13) for the cable is arranged ahead of the extrusion apparatus (15), that the braking apparatus (13) is designed for braking the cable in the axial direction but allows a rotational movement of the cable about its axis, and that at least one deflecting apparatus is arranged ahead of the braking apparatus.
