Abstract
An off-loom take-up for winding a cloth roll from woven cloth coming from a loom which includes a frame and a pair of spaced take-up rollers carried by the frame, at least one of the take-up rollers is a driven take up roller. A drive motor with an output shaft drives the driven take-up roller, and a motor controller is provided for controlling the speed of the output shaft of the drive motor. A pivotal dancer roll assembly is carried by the frame and includes a pivotal dancer roll under which the cloth travels from the loom to the cloth take-up roll. A voltage sensor responsive to the movement of the pivotal dancer roll outputs a plurality of voltage signals correlated to a plurality of different pivotal positions of the dancer roll. An electronic limit processor is provided for receiving the voltage signals, the processor processing the voltage signals to generate a control signal which is output to the motor controller for controlling the drive motor.
