Abstract
Angular orientation of a straightener machine roll relative to the vertical axis thereof is achieved through the use of a pair of single acting hydraulic actuators imposing force against a roll support member on laterally opposite sides of a vertical plane through the roll axis, and vertical orientation is achieved through the use of a double acting hydraulic piston and cylinder unit to which the roll support member is attached. Corresponding servo valve mechanisms control fluid flow to the two single acting actuators and to the double acting piston and cylinder units, and both angular orientation and vertical orientation are selectively position or force controlled.
