摘要： A controlled deflection roll having a rotatable roll shell which is penetrated by a stationary shaft, a hydraulic bearing arrangement between shaft and roll shell, which is formed by individual hydrostatic bearing elements arranged axially beside one another, which each comprise a radially movable force element having an outer bearing pocket element, the outer bearing pocket element having a cylindrical outer bearing surface supporting the cylindrical roll shell hydrostatically on an inner shell circumferential line, and having an edge bearing unit provided at each end of the roll shell, the outer bearing pocket element (9) in each case being mounted hydrostatically on a spherical inner bearing surface (13) running concentrically with respect to the inner circumferential line of the roll shell (2).

摘要： In a roll apparatus formed by a top roll and a hydraulically supported bottom roll, which together form a roll nip, additional piston/cylinder units that can lift the hollow cylinder near its working position closing the roll nip are provided at least at the ends of the hydraulically supported bottom roll. Due to the geometric arrangement employed, this lifting function is operative only up to a predetermined position of the hollow cylinder relative to its crosshead, which is selected to be at a short distance before closure of the roll nip. The pressure in the piston/cylinder unit degenerates whenever the piston of the additional piston/cylinder unit is forced out of sealing contact with its respective cylinder when the predetermined position is reached.
