The crown on a steel strip in a rolling mill is controlled by a continuous rotational adjustment of an arbor in response to a control signal representing the current crown profile or deviation therefrom, the arbor being equipped with a series of eccentric rings fixed thereto, bearings surrounding the rings, and a continuous or segmented sleeve around the rings. Where the sleeve is segmented, use of an intermediate roll is suggested.
