ABSTRACT:
An apparatus and method for controlling the drive of an off loom take-up which winds cloth upon a cloth roll is disclosed. The off loom take up comprises a pair of spaced, driven take-up rollers upon which the cloth roll is supported and rotated. As cloth coming from the loom is directed to the cloth roll being wound, it passes underneath a pivotal directional roll which is supported on spaced pivotal arms. A motor controller controls an electric motor which drives the driven take-up rollers at a preset speed which allows the cloth to travel at the directional roll at a slightly slower speed than the speed at which the cloth travels leaving the take-off rolls of the loom. This establishes a predetermined downward "creep" in the movement of the pivotal directional roll. The downward movement of the directional roll is sensed by a detector. When the directional roll descends a prescribed distance, the detector momentarily sends a high speed signal to the drive motor which momentarily steps up the speed of the drive motor and the cloth roll being to take out the slack of the cloth. The preset speed is resumed and the high speed signal is discontinued. Conveniently, the tension of the cloth created by the directional roll can be adjusted to a desired tension by placing the detector object on a movable bracket so that the position at which the detector switch is activated may be varied in accordance with different descending horizontal positions of the directional roll.
