Title: Four-strand cable - is formed by twisting paired strands together in continuous process
Inventor: HOFMANN FRITZ
IPC: H01B13/04
Filed: 1978-01-19
Abstract: In developing a cable of four strands, cables are twisted together in pairs in a double twist, and then paired strands are then twisted together in a double twist, without interruption between the two stages. The individual strands of each pair are suitably drawn from their spools under equal tangential braking pressures by twisting frames rotating at different speeds. The twisted lengths of the paired strands are varied at random, and there is a constant twisted length for the four strands together. The pairs and the four-strand construction are twisted with or against each other. The system gives a single-stage manufacturing process, which gives a four strand cable where the strands remain embedded and do not reassert themselves against their twist.
