Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
A deflection controlled roll comprising: a fixed carrier; and a roll jacket rotatable about the carrier, the roll jacket being supported on the carrier via a plurality of support elements, each of the support elements including at least one cylinder-piston device for the formation of a contact force, at least one bearing shoe with a lubricating fluid supply, at least one pressure chamber, and at least one pressure fluid supply member associated with a pressure fluid supply; and the pressure fluid supply members, coupled to the pressure chambers of the cylinder-piston devices, comprising a plurality of pressure conduits, each of the pressure conduits being at least one of approximately the same length and approximately the same volume capacity for pressure fluid.
Claim 2
Dependent Claim
121 words
