ABSTRACT:
A cable stranding apparatus wherein back tension on wires drawn from spools thereof and helically wound around a central core is controlled by positive drive means controlling the speed of rotation of each spool about its own axis in a controlled proportion to the speed of rotation of the central shaft of such apparatus about its axis. This controlling of the speed of rotation of each spool about its axis is varied during operation of the apparatus in response to means sensing the back tension on at least one of the spool wires. As a result, the back tension on the wire from the spool controls the speed of spool rotation, and thus frees the wire from the effects of frictional problems at high speeds, and from the effects of variations of outer diameter of the wire on the spool as the wire is progressively unwound from the spool.
