Abstract
An apparatus is disclosed for drawing a length of wire through a die and for supplying the wire to a using station wherein the apparatus utilizes a mechanical variable-speed drive mechanism and a sensing arm for sensing the error between the consumption and feeding rates of the wire and integrating the same. An electromechanical apparatus couples the sensing arm to the variable-speed drive so that the full range of drive ratios of the variable-speed mechanical drive mechanism can be utilized without the occurrence of a pull-back force at the wire. The mechanical pivoting of the sensing arm is translated to an electrical signal by way of the electromechanical apparatus which incorporates a plunger for oscillatory motion in response to the pivoting of the compensator arm. An electrical device is sensitive to the displacement of the plunger in a manner to provide a signal having a linear relationship to the magnitude of the displacement by the plunger caused by its oscillatory movement. The electrical device is not in direct physical contact with the plunger, thereby providing a friction free transition of mechanical movement of the plunger to an electrical signal.
