It is the tension adjustment type of slip shaft, slip ring independent slip.Controlled by the tension system, compressed air at a certain pressure is applied to the shaft core to generate the friction torque between the friction part and the slip ring, thus achieving constant tension coiling.It can be applied to the range from extremely low to the highest tension, which is suitable for high speed, large error of material thickness, multi-stage tension control, high precision of tension control, and neat requirement of end surface winding.It is most suitable for biaxial central roll cutting machine.
