Support element for pressure equalisation and pressure equalisation with support elements.

摘要

The invention concerns a loading shoe for a variable-crown roll. The roll comprises a stationary roll axle (12), on which the roll mantle (11) is arranged revolving, said mantle being supported in the direction of pressing on the roll axle (12) by means of loading shoes (20) acting upon the inner face of the roll mantle (11), said loading shoes being loaded against the inner face of the roll mantle (11) by means of pressure fluid. The front face (21) of the loading shoe (20) that is placed facing the direction of rotation of the roll mantle (10) is shaped in such a way that, when the fluid flow (A) running on the inner face of the roll mantle (11) collides against the loading shoe (20), said front face (21) of the loading shoe is arranged to guide the fluid flow (A) so as to by-pass the loading shoe (20) from the desired side in order to reduce losses of power resulting from the fluid flows. The invention further concerns a roll (10) provided with loading shoes in accordance with the invention.
