Abstract

A press roll contains a stationary roll support or beam and a roll shell rotatable about the stationary roll support, the roll shell being formed of an easily deformable material. The roll shell is supported at a support surface located at the region of the roll support. This support surface can be convex and possess a larger radius than the radius of the roll shell, can be planar or concave. Guide surfaces possessing a convex profile laterally merge at the support surface. The support surface and the guide surfaces are provided with a pressure lubrication and possibly with hydrostatic bearing pockets. A support part or element can be movable in relation to the stationary roll support or beam in the manner of controlled deflection rolls.
