DEFLECTION COMPENSATING ROLL ABSTRACT OF THE INVENTION A deflection compensating roll is disclosed which com- prises a support beam, a roll shell rotatably mounted about and defining with said beam an intermediate space therebetween and at least one hydrostatic support element engaged between the beam and the shell for exerting a force against the interior of the shell. The surface of the support element facing the interior of the shell is provided with a plurality of recesses which are sup- plied with fluid so that a hydrostatic fluid cushion is formed between the face of the support element and the interior of the roll shell. The beam has a longitudinally extending chamber and means for sealing a first region of the chamber which communicate with the fluid receiving recesses from a second region of the chamber which communicates with the intermediate space between the beam and the shell. The first and second regions of the chamber respectively define a conduit for supplying fluid to the support element and a conduit for discharging fluid flowing into the intermediate space from the recesses. The sealing means may in- clude a tubular member disposed in the chamber with the end por- tions thereof being in fluid-tight engagement with the wall of the chamber. In this arrangement, the annular space between the outer surface of the tubular member and the wall of the chamber communicates with the intermediate space between the beam and the shell and serves as the conduit for discharge of the fluid, while the interior of the tube communicates with the recesses in the sup- port element and serves as the conduit for supplying fluid there- to. A device such as a scoop ring disposed in the intermediate space may be provided for feeding fluid from the intermediate space to the annular space between the tubular member and the wall of the chamber.
