ABSTRACT:
A controlled deflection roll contains support elements or groups of such support elements which support the roll shell in relation to the roll support with forces which differ with respect to one another in accordance with a predetermined function, notwithstanding the fact that the support elements are acted upon by the same control signal from a common control source. When using hydraulic support elements this can be realized by throttle elements or throttle means located in the infeed line to one of the support elements which, if desired, also can possess a cross-sectional area which differs from the cross-sectional area of the simultaneously controlled support elements.
