Unwinds / Rewinds

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.

Requirements:  This application required a rewind that would create a spiral wound roll.

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.
