ABSTRACT:
A tension control system for maintaining a substantially constant predetermined tension on material being unwound from or wound onto a roll of material. The control system includes a shaft for holding the roll of material and a motor coupled to the shaft for rotating the shaft at a predetermined speed to maintain the material at a substantially constant predetermined tension. The motor is mounted in a predetermined initial position and remains there when the material is at the predetermined tension. The shaft and motor are mounted to permit limited rotational movement of the motor relative to the frame in response to the tension on the material deviating from the predetermined tension. The system includes a displacement detector for detecting movement of the motor away from its initial preset position in response to the tension deviating from the predetermined tension. The system adjusts the speed at which the motor rotates the shaft by an amount based upon the displacement of the motor relative to its initial position to maintain the tension of the material at substantially the predetermined tension.
