INVENTORS: MARIO BIONDETTI and IGNAZIO MARCHIORO INVENTION: CONTROLLED DEFLECTION ROLL ABSTRACT OF THE DISCLOSURE A controlled deflection roll compris- ing a fixed support and a hollow shell rotatable about the support and displaceable relative to the support in the direction of a pressure plane. Between the support and the shell there is located at least one hydrostatic pressure or contact element which is effective in the pressure plane and serves for oppressing the roll shell against a counter roll and thus for forming the pressure force of the roll. Additionally, there is provided at least one hydro- static lift-off element which is effective in the opposite direction with respect to the contact or pressure element and serves for lifting-off the roll shell from the counter roll. The contact element and the lift-off element can be connected by hydrau- lic lines or conduits to a source of hydraulic press- urized fluid medium. A control device or means serves for the selective connection of a conduit of the contact element or the lift-off element with the source of hydraulic pressurized fluid medium and for simultaneously connecting the conduit of the element disconnected from the source with a drainage or out- flow line or conduit.
