ABSTRACT:
A loom cloth takeup having pivotally mounted arms A exerting a force upon a friction roll (F) has first and second control devices (E) and (H) respectively for controlling tension on the cloth ahead of the friction roll (F) and for controlling a motor (G) driving the friction roll (F) to afford full roll tension control during the build of the cloth roll. A regenerative DC motor drive (H) is provided to avoid slippage between the friction roll and the cloth during winding, and a center wind motor control utilizing a capacitor (I) in series with the motor imparts a negative slope to the speed load characteristic.
