ABSTRACT:
In a controlled deflection roll comprising a rotating shell forming the working roll periphery and a stationary beam extending lengthwise through the shell and spaced all around from the inner periphery of the shell, the space between the beam and the inner periphery of the shell, in the neighborhood of the operative plane, is divided into chambers by longitudinal seals and a number of transverse seals, the chambers have separate feed lines and each pair of adjacent chambers has a common transverse seal between them. Neighboring chambers are connected by a duct and non-return valves so that the transverse seal is always acted upon by the pressure of the higher-pressure chamber and pressed against the inner periphery of the shell. The chambers can be formed on the side of the beam facing the nip and also on the side remote from the nip and can also be individually filled with pressure fluid at different temperatures.
