ABSTRACT:
A back up roll assembly for supporting an intermediate roll and an upper work roll consists of a plurality of rotatable rollers spaced apart on a common shaft by fixed saddles and in engagement with the intermediate roll. The number of saddles exceeds one more than the number of rollers so that the back up roll assembly begins and ends with a saddle, each saddle being engaged by a piston cylinder assembly mounted in a frame, which frame takes up all of the rolling load and adds rigidity to the compensating system. Each piston cylinder assembly controls the positioning of its saddle and its neighboring rollers to exert a localized influencing effect onto the intermediate roll to compensate for, and/or control roll deflection.
