Abstract

Deflection adjustment roll that includes a rotating roll jacket, a support member axially extending through the roll jacket, a plurality of at least one of hydrostatic and hydrodynamic support elements located next to one another with a predetermined spacing in an axial direction of the roll jacket to support the roll jacket on the support member, and a fluid removal device that removes operating fluid collected on an inner surface of the roll jacket during operation and that forms a fluid ring that circulates around the plurality support elements on the inner surface of the roll jacket. The fluid removal device may include a plurality of fluid stripping elements formed on the plurality of support elements that laterally protrude from each support element in a direction of a neighboring support element to strip the fluid circulating around the plurality of support elements from the roll jacket in the flow channels formed between the support elements.
