Abstract:
1. A deflection controlled roll comprising: a rotating roll jacket; a rotationally fixed yoke arranged to axially pass through said roll jacket; at least one hydrostatic support element is arranged on said yoke to exert a supporting force on an inner side of said roll jacket; said at least one hydrostatic support element comprising a pressure space, a hydrostatic pocket, and at least one device coupled to said at least one hydrostatic pocket; said pressure space is structured and arranged to receive pressure fluid to charge said at least one hydrostatic support element; said at least one hydrostatic pocket is structured and arranged to receive pressure fluid via the at least one device and separately from said pressure space; and said at least one device being one of a capillary and a pre-restrictor; a constant fluid pressure being applied at an end of said at least one device remote from said at least one hydrostatic pocket; and a pressure difference at said at least one device decreasing when a pressure of said pressure space increases and the pressure difference at said at least one device increasing when the pressure of said pressure space decreases.
