ABSTRACT:
Changing relative positions of conductor pairs along a telecommunications cable core by passing the pairs, as they approach a core unit forming means, through guides which are held in relative positions in a guide channel. The channel extends in a plurality of directions and has inner and outer channel portions which are preferably arcuate and lie upon arcs of circles. The guides are moved along the channel and from channel portion to channel portion, movement being alternately in each direction. This movement changes the positional relationship of guides in one channel portion to those in the other.
