Abstract

A method influences the geometry of a rolled item in a controlled manner. In the method, the rolled item is transformed from an initial condition into an intermediate or final condition by rolling with the aid of a rolling stand having at least one processing assembly. An improvement in the geometry of the rolled item, particularly during processing of asymmetric rolled items, is achieved in that the at least one processing assembly is operated in a force-controlled manner on the basis of a desired force.
