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.
