ABSTRACT:
A controlled deflection roll comprising a stationary roll support and a roll shell rotatable about the roll support. The roll shell is guided in radial direction upon the roll support in order to perform displacement movements, typically lift movements. The controlled deflection roll is equipped with a shutoff element, a slide or a valve, which upon exceeding a given displacement magnitude of the roll shell causes outflow of pressurized fluid medium from a pressure line, and thus, prevents the development of the full pressing or contact force which otherwise could lead to destruction or damage of the roll shell. In an overflow line, branching-off of the pressure line, there can be arranged a residual pressure regulator equipped with valve means or throttle means for preventing drop of the pressure in the pressure line below a desired value.
