Abstract
A roll has a rotating roll shell and a stationary beam extending longitudinally through the shell and leaving an annular space between it and the inner periphery of the shell. A longitudinal chamber having a supply pipe for pressure fluid is formed in the space between the shell and beam and is divided by a sealing system comprising transverse end seals and strip-like longitudinal seals extending on both sides of the plane of action of the roll. Each longitudinal seal is formed by a number of sealing strips staggered in the peripheral direction. A line opens between each pair of sealing strips and contains a one-way valve and leads into an outlet. The one-way valves are set to open at pressures which progressively decrease towards the longitudinal chamber. The transverse longitudinal seals can also be made up of a number of sealing strips staggered in the radial direction.
