Abstract
The invention relates to an arrangement for displacing a roll, which is hydrostatically journalled by its axle (1) on support structures and positionable in its working position by means of a bearing, through a rapid movement of the bearing out of its said working position. The journalling comprises at each end of the roll at least one loading element (2-4) pressurizable with a hydraulic medium and at least one support element (5). The arrangement of the invention comprises a valve control piston (9), delivering a hydraulic medium required for the pressurization of said at least one loading element (2) and positioned in a valve cylinder (8), said control piston (9) being provided with a positioning valve (10) on the face of the control piston (9) pointing towards the loading element (2), the face of the control piston (9) opposite relative to the positioning valve (10) being coupled with a pressure line (LP) of the hydraulic system for focusing a holding pressure on the control piston (9).
