ABSTRACT:
A hydrostatic self-loading controlled deflection roll has a central, hydraulically operated shoe which extends substantially the entire cross-machine width of the rotating roll shell, and two outboard shoes disposed, in the cross-machine direction, outside of the nip loading zone. The use of the outboard shoes permits the use of a single, full-length nip shoe within the nip loading zone, which simplifies control and provides for more uniform temperature distribution. The outboard shoes also provide better crown control. The outboard shoes are preferably disposed within a head flange area of the roll, at the location where spherical bearings would normally be present in a conventional roll. A bearing ring is disposed axially outside of the head flange and around a portion of a bearing box at either end of the roll for rotatably supporting the roll shell about bearings in the bearing box. A barrier seal is disposed between the stationary roll shaft and the roll shell intermediate the bearings and outboard shoes.
