center winding

Rewind rolls are driven from the core only

With a single motor, the maximum diameter is limited, but the overall cost of the machine is less than a center-surface winder.

Often paired with differential shafts

These shafts transmit torque evenly, despite diameter, so materials with gauge bands are able to be ran.

Best for high speed film processing

Due to the rider roll, air entrapment is minimized, allowing thin extruded films to be run much faster than possible on other machines.
