surface winding

Rewind rolls are driven from the surface only

This allows the tension to be transmitted directly to the surface of the finished roll, so that the tension remains constant from core to diameter.

Very little stretch on material

The torque arm developed on center winders is not present, so stretchy films can be wound at core without deforming, where pure center winders would have difficulty.

Best for large diameters

With all the force applied at the surface, these winders can build the largest, heaviest rolls possible.
