A method of controlling the shape and thickness of a strip workpiece in a rolling mill wherein an electrical signal is generated representative of a bending pressure applied to the rolls, another electrical signal is generated as a function of a fixed relation between the bending pressure and a constant and still another electrical signal is generated representative of the total force applied on the backup rolls. The signals representative of said fixed relation and of said total force are combined to provide a control signal to vary the rolling load to control the shape and thickness of the workpiece to eliminate the effect of the reaction forces on control of the rolls which otherwise tends to cause production of workpieces which do not meet the desired specifications.
