At present, the paying-off tension control of a back-twist stranding machine in China is divided into two major categories.
For passive pay-off, the following three categories are also used
1) Use of mechanical friction belts, which tend to wear and are not uniformly tensioned.

The back-twisting stranding machine is a rotating body, and a magnetic powder brake is installed in the rotating body. When the magnetic powder brake works, the magnetic powder is not uniformly distributed due to the action of centrifugal force. The output torque is inaccurate.
