Abstract
An anti-deflection roll including a rotating roll sleeve, a support member or yoke that extends along the axis of the roll sleeve or jacket, and a plurality of hydrostatic and/or hydrodynamic support units, partially positioned within the support member and arranged in a predetermined spaced relation to each other, to support the roll sleeve in an axial direction. Between an inner surface of the roll sleeve and a support surface of each support unit an intermediate fluid coating layer may be formed.

An anti-deflection roll comprising:
- a rotating roll sleeve having a rotational axis;
- a support member extending through the rotating roll sleeve and supporting the rotating roll sleeve;
- a plurality of support elements, arranged along the support member in a spaced relation to form gaps between adjacent support elements and arranged substantially parallel to the rotational axis of the rotating roll sleeve, comprising one of hydrostatic and hydrodynamic support elements;
- an intermediate fluid coating layer disposed between each support element and an inner surface of the rotating roll sleeve;
- and
- a plurality of fluid scraper units positioned adjacent the inner surface of the rotating roll sleeve and extending along an axial extent of the rotating roll sleeve;
- and
- each of the plurality of fluid scraper units being aligned with the gaps formed between adjacent support elements.

An anti-deflection roll comprising:
- a support member comprising a plurality of support devices;
- a roll sleeve having a rotational axis rotatably supported by the plurality of support devices;
- the plurality of support devices being spaced to form a gap having a predetermined gap distance between adjacent support devices and arranged substantially parallel to the rotational axis;
- and
- a plurality of fluid scraping devices positioned adjacent to an inner surface of the roll sleeve, each fluid scraping device being circumferentially spaced from the support devices and associated with a respective gap between adjacent support devices.
