ABSTRACT:
A machine for manufacturing cables by stranding individual wires, comprising: a pay-out apparatus having four pay-out reels and fixed supports therefor; a stranding apparatus situated after the pay-out apparatus and comprising a forming die receiving the individual wires; a take-up apparatus having a take-up reel, a support for the take-up reel, and a cable-puller for pulling the cable through the die at a predetermined speed; and further comprising wire-tensioning devices disposed between each of the pay-out reel supports and the die, each of the wire-tensioning devices comprising a guide member for one of the wires, disposed at a fixed location and coaxial with a respective one of the reels, a zone situated before the guide member for non-guided passage of a portion of the wire from the reel to the guide member, a motor for driving each of the pay-out reels at a variable speed of rotation, the speed being sufficient to cause the portion of wire to assume the form of a loop under the effect of centrifugal force, thus tensioning the wire through the centrifugal force, and apparatus independent of the cable-puller for controlling the variable speed of rotation, the speed of rotation being constantly the same for all the pay-out reels.
