Abstract
Pinch roll apparatus has a pair of pinch rolls each having a diameter between 300–1500 millimeters positioned to form a nip through which metal strip can be continuously fed. The pinch rolls are positioned one above the other with the axes of the pinch rolls offset in the direction of travel of strip, with the upper pinch roll offset positioned between 10 and 130 mm downstream of the direction of travel of the strip through the pinch rolls. A rotational drive counter rotates the pinch rolls to cause strip to pass through the nip of the pinch rolls. A tilt drive tilts the upper pinch rolls by a tilt between 0.5 and 5.0 mm to control steering of the strip passing through the pinch rolls. The steering of the tilt drive may be automatically controlled through a controller actuated by a sensor.
