Abstract

Roll arrangement that includes a deflection controlled roll and a counter roll. The counter roll and the deflection controlled roll are arranged to form at least one nip. The deflection controlled roll includes a rotating roll jacket, a carrier axially passing through the roll jacket, and support elements arranged between the roll jacket and the carrier. A plurality of the support elements, located at a nip side of the deflection controlled roll, are structured and controllable so that at least some of the plurality of support elements assume a position retracted from the roll jacket during a start-up operation of the deflection controlled roll. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
