An arrangement for controlling the pressing or line force of a controlled deflection roll comprises a common adjustment or setting element for separate controllable supporting force sources or force-applying sources. Between the adjustment element and the force-applying sources there are connected converters for generating control signals in accordance with a conversion function which, depending upon the nature and/or site of the force-applying sources, has different characteristics. The converter enables interposing correction signals.

In an arrangement for controlling the pressing force between a counter element and a controlled deflection roll having a roll shell and a roll support for supporting said roll shell, wherein force-applying sources distributively arranged in axial direction and supported at the roll support serve to press the roll shell against the counter element over its entire length or at one or a number of regions thereof, and wherein groups of force-applying sources can be separately controlled and there is provided a common adjustment element for the pressing force following which there is arranged for each group of force-applying sources an individually adjustable regulation element, the improvement which comprises: said regulation element being structured as control converters; the common adjustment element serving for generating a control signal x; said control converters converting the common control signal x generated by the common adjustment element in accordance with the relationship yi=aix+bi into force-proportional group control signals y (Y, Y2 . . . Yn); and in each regulation element the values ai, bi are essentially constant over the entire range of the pressing forces and are dimensioned in such a manner that in the presence of two predetermined values of the mean pressing force there prevail at a rolled product minimum deviations of the product profile over the roll shell length.
