Static Control on Unwind and Rewind Rolls

As the roll diameter changes in unwind and rewind applications, the efficiency of a static bar will decrease as the static bar gets futher away from the roll.

The NEW Simco ROLL FOLLOWER , equipped with a high efficiency static control bar, is designed for permanent mounting to an unwind or rewind stand for continuous control of static electricity. Photo sensors included in the system detect changes in the outside diameter of the material roll and automatically move the static bar to maintain a predetermined distance to the surface of the roll, regardless of the web speed. When the roll is finished the static bar retracts to its resting position, away from the roll. The system PLC allows the operator to easily program the unit for either unwind or rewind functions. The result is maximum static neutralizing efficiency regardless of roll diameter throughout the entire unwind or rewind process.
