ABSTRACT:
A device for guiding a strip so that it is kept in a predetermined lateral position as the strip moves from a supply to a take up reel. The device includes mechanical sensors sensing the lateral edges of the strip, the sensors being coupled by a differential linkage system to a frame in which is mounted a pair of rollers, one each side of the strip and in contact therewith. The frame is pivoted about an axis perpendicular to the strip so that if the strip shifts laterally the sensors move the differential linkage to pivot the frame and thereby cause the rollers, one of which is driven or braked, to impart a component of motion to the strip to move it back to its initial position.
