Pinch roll apparatus comprises upper and lower pinch rolls (60A, 60B) each having a diameter between 300-1500mm positioned laterally adjacent each other to form a nip between them through which metal strip (12) can be continuously fed and a rotational drive capable of counter rotating the pinch rolls (60A, 60B) to cause the strip to pass through the nip between them. The axes of pinch rolls (60A, 60B) are offset in the direction of travel of the strip through the pinch rolls with the upper pinch roll offset positioned downstream of the direction of travel of the strip, and a tilt drive is capable of tilting the upper pinch roll (60A) by a tilt angle, measured at the edge of the strip, relative to the lower pinch roll to control steering of the strip, such that (R upper min + h min + R lower min - |Tilt os-ds |)/(R upper max + h max + R lower max )>cos(¸). |
