Abstract
In a method for cold-rolling sheets and strips, measured values which characterize the surface evenness, especially the tensile stress distribution, are formed on the delivery side of a rolling mill and, in dependence thereon, adjusting members of the rolling mill are actuated which form part of at least one regulating circuit for the surface evenness of the rolled sheets and strips. Incorrect adjustments and disruptions in the rolling process on the basis of the different time responses of the individual adjusting members are avoided by adjusting the adjusting members at speeds so matched to one another that during at least a portion of the adjusting time, the ratio of the adjustments of the participating adjusting members remains constant, and all adjusting members reach their desired values simultaneously.
