Abstract
To provide symmetrical communication cables, especially wiring cables for telephone exchange installations, with connectors at the cable ends, in a simple manner, the individual groups of pairs of the cable core consist of a flat cable, which is formed into a group by twisting or torsioning. The pairs of each flat cable are connected to each other by means of flexible holding elements which are cemented or welded to the pairs on one side. In the manufacture of such a communication cable, the pairs of a group are first arranged along the generatrix of a cylinder and are temporarily secured in this configuration by means of a holding helix. The holding helix is cemented or welded to the surface of the pairs and subsequently cut open between two adjacent pairs in the same operation.
