<p>19 A roll, for use in the dewatering press of a paper machine or a calender roll, having adjustable zones. The roll has a non-revolving massive central axle, on which a substantially cylindrical roll mantle is journalled to rotate. Between the central axle and an inner face of the roll mantle, a loading piston-cylinder group or block arrangement is situated, having pistons which can be loaded by hydraulic fluid pressure against the inner face of the roll mantle so as to adjust distribution of pressure in zones along the roll. The loading piston-cylinder group or block arrangement comprises a substantially elongated or oblong cylinder group or block fitted into an axially-extending groove along the central axle, with the cylinder group or block being a separate component from the central axle itself. The cylinder group or block is supported only in the regions of the longitudinal ends thereof upon the central axle, by way of particular supporting arrangements.</p> |
