The unpowered unwind stand uses a hysteresis-type magnetic brake to control web tension. Torque control is accomplished by turning the large knurled adjustment ring. Repeatability and accuracy are excellent.
A motorized unwind has a manual control on the unwind tower which controls the motor speed. An optical sensor keeps the material loop within the desired limits.
Cantilever-style unwind stands, both powered and unpowered, are available. They can be bench-mounted and are simple to use.
