ABSTRACT:
Making a cable core unit in which pairs of twisted conductors are formed upon individual twisting machines, the twisted conductor pairs then fed `in-line` to a core forming device by passing the pairs through a tension reducing means which reduces tension in each pair while allowing the lengths of the pairs to be different from pair-to-pair as they move into the core forming device. Built-in tensions and twisted core units are thus avoided. Also provided is a tension equalizing device which averages out the tensions between conductor pairs.
