Forming cable core units.

摘要

Making a cable core unit in which pairs (32) of twisted conductors (30) are formed upon individual twisting machines (10), the twisted conductor pairs then fed 'in-line' to a core forming device (13) by passing the pairs through a tension reducing means (60, 62, 64, 66) 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 (34) which averages out the tensions between conductor pairs.
