摘要： A method for fitting a roll mantle of a tubular roll used in a paper machine or equivalent with glide bearings and a tubular roll. The roll mantle is supported on a stationary roll axle by hydraulic glide bearing elements acting upon the roll mantle and/or upon the roll ends. The bearing elements are loaded hydraulically by the pressure of a first pressure medium. The roll is loaded from outside radially in the direction of at least one plane, i.e. in a so-called principal loading direction. The roll mantle is supported on the roll axle by the glide bearing elements which act radially substantially in the principal loading direction in opposite directions and which are provided with a device for regulating the braking pressure provided by a second pressure medium, so that in the principal loading direction, the roll mantle is allowed to move over a certain distance. When the roll mantle approaches its preset extreme position in that direction, the movement of the roll mantle is braked and slowed down by the regulation device, and finally the movement is stopped in its extreme position by the glide bearing elements.

摘要： A method for providing a tubular roll mantle of a roll for a paper machine or equivalent with glide bearings and a roll including glide-bearings. The roll mantle is supported on a stationary roll axle by hydraulic glide-bearing members acting upon the roll mantle or upon the roll ends. The bearing members are loaded hydraulically by a pressure medium. The roll mantle is supported on the roll axle by at least one pair of glide-bearing members which acting radially and/or axially in opposite directions. When an outside force that shifts or attempts to shift the roll mantle in the direction transverse to the main loading direction and/or in the axial direction is applied to the roll mantle, the pressure in the glide-bearing member placed at the side of the higher loading is adjusted to a level higher than the pressure in the glide-bearing member acting in the opposite direction so that the outside forces are neutralized. In another embodiment, the roll mantle is permitted to be shifted over a certain distance in the main loading direction. When the roll mantle approaches its preset extreme position in this direction, the movement of the roll mantle is brake down, and finally the movement is stopped in its extreme position by the glide-bearing members.
