INVENTOR: IGNAZIO MARCHIORO INVENTION: CONTROLLED DEFLECTION ROLL ABSTRACT OF THE DISCLOSURE A controlled deflection roll having a roll shell rotatably mounted at its ends at a stationary roll support. Pressure or support elements are located between the roll shell and the roll support. The bearing or mounting arrangement of the roll shell at the roll support is provided with play, in a direction opposite to the direction of application of the force exerted by the pressure elements. In such play there is effective a force opposing the direction of the force of the pressure elements. If this force is exceeded by the force of the pressure elements, then a control device limits the force exerted by the pressure elements to a value which is not dangerous for the roll shell. According to a preferred con- struction the control device is constituted by a hydraulic shutoff element which, in the case of a hydraulic controlled deflection roll, opens an outflow channel leading from the pressure line or conduit, and thus, lowers the pressure effective in the pressure line.
