Abstract: An electrical power cable includes plastic-insulated conductors and a single wire, which is enveloped by a lengthwise incoming insulating tape and is twisted together with the conductors, all of which are surrounded by a common sheath. The conductors and the single wire are twisted together with alternating stroke directions (SZ), and the tape is loosely placed around the single wire in the form of a strand with opposing edges of the tape having alternating directions of rotation along the length of the strand.

Abstract: A device for the reverse-twisting of stranding elements (4), comprising a stationary guide disk (1) and a twisting disk (2) located at a distance from the guide disk and able to rotate around its axis. At least one filament-shaped, tension-proof support element (7) is located between the guide disk (1) and the twisting disk (2). At least one holding element (5) is mounted on the support element (7) and is located at a distance from the guide disk (1) on one side, and from the twisting disk (2) on the other. The holding element (5) contains axial passage holes (6) for the stranding elements (4). The ends of the support elements (7) are affixed in holders (9), which are able to tilt and/or rotate with respect to the twisting disk (2).
Abstract: An apparatus to reverse-twist cable elements in the discharge direction, while at the same time the resulting twisted discharge is taken up in a storage path includes a mandrel for expanding the cable elements prior to the twisting thereof in the discharge direction.
Abstract: A light wave conductor or fiber optics is withdrawn from the peripheral groove of a rotating storage disc using a deflection pulley or the like rotating in a plane that runs tangential to a circle through the middle of the groove, a pivotal guide lever for the fiber conductor serves as input for speed control of the disc drive. In case of plural withdrawal equipment, the discs are vertically staggered and overlap.
