ABSTRACT:
In the manufacture of a cable unit (30), which comprises a center portion and a plurality of layers of twisted conductor pairs, the pairs in the center portion and in each layer are oscillated in alternately opposite directions after which the unit is bound and taken up in a stationary container (62) by a system (100) which distributes the unit in a predetermined pattern of varying size convolutions. This distribution, which results in a dense package of a cable unit having a free end that facilitates testing of the unit during takeup, is accomplished while the speed at which the unit is being advanced and distributed into the varying size convolutions is maintained substantially constant.
