ABSTRACT:
So as to be able to perform layer-wise SZ twisting of twisting elements of electric cables by means of a twisting plate with changing direction of rotation, the twisting plate is preceded at a distance by a twisting head which revolves with constant speed and direction of rotation. The twisting plate itself is provided with guide holes for guiding the twisting elements, which holes are arranged on at least two concentric pitch circles. Advantageously, the twisting plate has, besides a central guide hole, six guide holes on a first pitch circle and twelve guide holes on a second pitch circle. The distance between the twisting head and the twisting plate should be greater than the length of a section with the same twisting direction in the finished twisted material.
