Abstract
PURPOSE: To make it possible to control the shaping of a plate by actuating a piston in a stationary cylinder and then actuating a piston in a rotary cylinder so that fluid pressure is fed from the stationary side to the innerface of a sleeve in a rolling roll even during the rotation thereof.
CONSTITUTION: When a feed pipe 11 is subjected to a piston movement in the direction of opening a check valve 8 by a cylinder 17', causing the check valve 8 to be forcibly opened to loose its checking function, so that a cylinder chamber 17 and an annular pressure feeding groove may be maintained under the same pressure. When controlled pressure is fed into a cylinder chamber 22 of the stationary cylinder 17, the corresponding pressure is generated in the annular pressure feeding groove, and a pressure medium is applied to the contact surface of a sleeve (not shown) fitted onto the outer periphery of an arbor 1a in a rolling roll, for partially swelling the sleeve, thereby the control of shaping of a plate can be practiced.
