Abstract
The present invention relates to a loop follower control system for use in a mechanical press or other machine installation for the purpose of controlling the amount of stock loop between the straightener and the press. An idler arm engages the loop of stock between the straightener and the press, and is connected to an potentiometer to develop a current or voltage proportional to the deviation of the idler arm from the desired position. The control current or voltage developed controls an eddy current drive to increase or decrease the speed of the rollers and straightener depending on the amount of error indicated by the control signal.
