摘要

A method for reducing the electrical coupling in communications cables constructed of bundles in which in a first twisting stage of a two stage operation sections of opposite phase are formed in pairs in the twisted units and in the second twisting stage, adjacent twisted units are related to each other in such a manner that two adjacent twisted units always have the same number or approximately the same number of parallel sections of the same and opposite phase over their entire length. In one disclosed apparatus for carrying out this method an aperture disc, which is rotatable about the twisting axis and whose angular position is variable, is arranged in front of each twisting nipple in the first twisting stage.
