Abstract
Abstract FLEXIBLE MATERIAL IS WOUND ONTO A FORM DRIVEN BY ELECTRIC MOTRO OPERATED TRANSMISSION. TO MAINTAIN CONSTANT TENSION ON THE MATERIAL BEING WOUND, BRAKE PREVENTS OR REGULATES ROTATION OF THE WINDING FORM. A TORQUE SENSING CIRCUIT IS CONNECTED TO THE BRAKE TO POSITIVELY HOLD THE FORM AND PREVENT ITS ROTATION IN AN UNWINDING DIRECTION UNTIL THE DRIVING TORQUE OF THE TRANSMISSION REACHES A PREDETERMINED VALUE.
