Tensioning torque can be varied infinitely from near zero (off) to rated torque by varying input current.
||Brakes provide smooth, variable tensioning torque for unwinding (payout) of film, fabric, wire or any web.|
||Clutches provide the same smooth tensioning torque for rewinding webs.|
Constant Tension Controls
A Placid Industries power supply and follower arm potentiometer or ultrasonic sensor may be used to maintain constant tension, even when roll diameters are changing.
