Abstract

An arrangement containing a controlled deflection roll which is supported by means of support or pressure elements against a roll support or beam. There is also provided a regulation arrangement for regulating the position of the roll shell, wherein the position of the roll shell at least at both of its opposed ends is detected by position sensors or feelers and deviations from a set or reference value are processed into two adjustment or positioning magnitudes which act upon the support or pressure elements. Both of the adjustment magnitudes are formed while taking into account a possible difference between both of the reference value-actual value differences and thereafter weighted and grouped together with further adjustment magnitudes and inputted to the support or pressure elements.
