Forming cable core units |
(57) 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.
