Abstract
Abstract Apparatus for precisely measuring the length of feed of continuous strip material as the strip material progressively and intermittently moves into a press or the like for operation thereupon. Rotor mechanism engages the strip material or engages a strip feed roll and rotates with movement thereof. The rotative position of the rotor mechanism is automatically noted at the termination of a feed operation of the strip material. The apparatus thus is capable of indicating and/or correcting and/or controlling the length of travel or length of feed of the strip material.
