ABSTRACT:
A controlled deflection roll contains a stationary support and a roll shell rotatable thereabout. The support has a central bore for the infeed of pressurized fluid medium. In the central bore there are located partition walls and infeed tubes, which deliver to individual sections of the stationary support the pressurized fluid medium at different pressures. The first section of the bore at one end of the stationary support serves for the withdrawal of the medium from the intermediate space or chamber between the roll shell and the support. The partition walls are held in spaced relationship by spacer tubes and secured by means of a tie or tension rod. Each partition wall consists of two telescopically displaceable parts, conjointly limiting a groove for a seal, and the seal can be pressed against the wall of the central bore by drawing together the telescopically displaceable parts.
