Double twist strander

A double twist strander is used to bunch or twist several wires together to a strand or to bunch or twist already insulated conductors together to a more compplex composite. A double twsit strander twists the material together through a rotation stranding bow, which is rovolting around the take-up bobbin for the finished product. By doing this the material ist twisted twice per revolution of the stranding bow around the bobbin. A related principle - the single twist bunching - is a slower process, however creates usually rounder strands.
Important production parameters of double twist stranders are the size of the take-up bobbin, the revolution speed of the stranding bow and the lay-length.
