ABSTRACT:
A controlled deflection roll equipped with a control arrangement, wherein at the controlled deflection roll there is carried out a groupwise control of the support elements in a manner such that each commonly controlled group of support elements contains at least one support element which does not neighbor any one of the other of the support elements of such group which are effective in the same direction, or such one support element is operatively correlated with at least one support element of the group which is effective in an opposite direction. In the latter case where support elements of the common group are effective in opposite directions they may however neighbor one another in the axial extent of the controlled deflection roll. In this way deviations of the mean or average value of the product profile or sectional shape of the rolled product can be reduced, without the expenditure in the number or construction of the support elements or their controls having to be increased.
