ABSTRACT:
Downstream of an uncoiler, a stretch-bend leveler is provided in a strip line to correct curvature in the strip plane. One or more rollers of the stretch-bend leveler are swingable about a horizontal or vertical axis at the end of the roller in response to a measurement of the longitudinal edge arcs of the strip to effect correction.
