ABSTRACT:
Deflection controlled roll. A deflection controlled roll is comprised of a fixed carrier and a roll jacket rotatable about the carrier, with the roll jacket being supported on the carrier via several support elements, wherein each of the support elements has at least one cylinder-piston device, for the formation of a contact force, and a bearing shoe with a separate lubricating fluid supply and wherein the fluid supply of pressure chambers of the cylinder-piston devices is accomplished at least in separate groups, via pressure conduits, with the deflection controlled roll, even though being supported via large number of support elements, being produced in a vibration damping-manner in a simple construction, wherein the pressure conduits have substantially the same length and/or the same volume capacity for the pressure fluid.
