25011-19 ABSTRACT OF THE DISCLOSURE In order to fix the relative axial position of a roll of a rolling mill and particularly when rolling asymmetrical profiles to improve the maintenance of tolerances for flange thicknesses of rolled sections, at least one roll is provided with a double acting hydraulic cylinder for axial positioning of the roll. The axial position is held fixed by an actual value-set value comparison by a control device. The actual value measurement of the roll axial position during an operating pass in which the rolls have changing axial forces is taken as close as possible to the rolled section for elimination of the position shifts due to compressibility or flexibility of components.
