Unwind apparatus

By designing a belt-driven unwind to have two distinct belt tension areas, the belt pressure against the unwinding roll can be decreased. The belt-driven unwind can have a higher belt tension section for proper belt tracking and to prevent slippage at the drive roller, and the belt driven unwind can...

Zusammenfassung:By designing a belt-driven unwind to have two distinct belt tension areas, the belt pressure against the unwinding roll can be decreased. The belt-driven unwind can have a higher belt tension section for proper belt tracking and to prevent slippage at the drive roller, and the belt driven unwind can have a lower belt tension section for the portion of the belt in contact with the unwinding roll. In this manner, the belt-driven unwind can be used with soft, bulky tissue rolls without damaging the rolls like a conventional belt-driven unwind.
