Deflection controlled roll

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, at least one 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;
• said at least one device being one of a capillary and a pre-restrictor;
• 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,
• wherein the deflection controlled roll is structured and arranged to utilize thermally induced roll expansion and relief to effect a path load profile of the deflection controlled roll, and
• wherein a constant fluid pressure is applied at an end of said at least one device remote from said at least one hydrostatic pocket.
