<p>A deflection-compensated roll, in particular a roll with a composite shell, which includes: a stationary roll shaft (1) provided with a loading cavity (4) for a pressurized medium and for a loading element (10), and a roll shell (2) arranged to rotate around the roll shaft and loaded by the internal loading element which is loaded in the loading cavity (4) radially against the inner surface of the roll shell (2). The loading element has recesses which are open towards the inner surface of the roll shell and form chambers (11, 12, 12') with the inner surface of the roll shell, a pressurized medium being passed into said chambers. In accordance with the invention, for jprofiling the roll shell in the axial direction of the roll shell, i.e. in the cross direction, a pressurized lubricating an dprofiling medium is passed to the loading element, which includes loading an dprofiling shoes placed one after the other in the cross direction, of which rows the middle one forms profiling chambers with the inner surface of the roll shell. A profiling medium is fed separately into the middle lubricating chambers (11) and, to ensure the stability of the lubricating film, a pressurized lubricating medium is passed into the lubricating chambers (12, 12') situated on the sides.</p> |
