Verfahren zum Bewehren elektrischer Kabel von ungleichmässigem Durchmesser durch Drähte.
Bei einem Kabel, das in gewissen Abständen verstärkte Steifen aufweist, wie dies z. U. durch den Einbau von Selbstinduktionsspulen bedingt ist, bilden sich, wenn die Anzahl der Bewegungsdrähte so gewählt ist, dass auf den) schwächeren, normales teilt des Kabels eine geschlossene Drahtlage entsteht, an den stiirkeren Stellen des Kabels freie Räume zwischen den Bewehrungsdrähten, so dass das Kabel an diesen Stellen der Zerstörung ausgesetzt ist.
Solche Zwischenräume können dadurch vermieden werden, dass an den verstärkten Stellen die Schlaglänge der Bewehrung dem wachsenden Durchmesser des Kabels ent- sprechend vorkürzt wird ; hierdurch wird jedoch die Zugfestigkeit des Kabels beeinträchtigt.
Die Erfindung besteht nun darin, dass die Bewehrungsdrähte auch an den verstärkten

Method of reinforcing electrical cables of irregular diameter with wires.
In the case of a cable that has reinforced stiffeners at certain intervals, as z. Due to the installation of self-induction coils, if the number of moving wires is chosen so that a closed wire layer is created on the) weaker, normal parts of the cable, free spaces between the reinforcing wires at the stronger points of the cable, so that the cable is exposed to destruction at these points.
Such gaps can be avoided by shortening the length of the reinforcement at the reinforced points in accordance with the growing diameter of the cable; however, this affects the tensile strength of the cable.
The invention now consists in that the reinforcing wires also on the reinforced

Gaps are laid out with auxiliary wires, so that a closed reinforcement is created everywhere.
The help. The wires are brought to the cable in one operation with the wires passing through, either in the same machine or in a special machine.

at the nipple) d is applied. This is now exchanged for another nipple after the machine has stopped, the passage opening of which corresponds to the diameter of the reinforced point.
If the machine continues to run, the wires a and f initially form a double reinforcement, but gradually change into a single, closed reinforcement at the conical part of the cable.
