ABSTRACT:
A chockless work roll support and positioning apparatus and method comprises a pair of brackets for each end of each work roll and having a pair of work roll support rollers rotatably mounted on each bracket. Each bracket is connected to at least one actuator means, such as a hydraulic piston/cylinder assembly, preferably one actuator means for each support roller. The actuator means are actuated through a servovalve, by position or pressure signals to position the support rollers at desired positions and to exert a desired pressure between the respective support rollers and the corresponding work rolls. By such signal control, the work rolls may be balanced, bent in the upstream or downstream horizontal direction, upwardly or downwardly, or may be placed in offset or cross-rolling position.
