Abstract

Regulation of the thickness of a strip treated by a rolling mill, particularly a cold rolling reversing mill, starting from an uncoiler driven at variable speed, of the type according to which the angular velocity of the uncoiler is acted on, comprises raising the linear velocity (V1) and the variations (J1) in strip thickness entering the rolling mill, raising the linear velocity (V2) of the strip leaving the mill and regulating the agular velocity of the uncoiler in such a way that (V1) (V2) and (J1) satisfy the relationship. V1 = r, V2 - r V2J1 in which (r) is the ratio of the strip thickness at the outlet and inlet to the rolling mill.
