A controlled deflection roll having a stationary roll core or support and a roll shell mounted to be rotatable about the stationary roll support. The roll shell is supported upon hydrostatic pressure or support elements, each of which possesses a number of bearing pockets flow connected by means of throttle channels with a pressure chamber. The pressure elements are in the form of plates dispositioned in the intermediate space between the inner surface of the roll shell and the outer surface of the stationary roll support or core. This stationary roll support can have a substantially cylindrical or planar outer surface at the location where it is engaged by the pressure element. The pressure element can be retained in position by pins secured at the stationary roll support or core, these pins engaging with clearance or play into recesses of the related pressure element. The pressure element also can take the form of an elongate strip or ledge having a number of seals bounding separate pressure chambers. |
