ABSTRACT:
A support or pressure element for a controlled deflection roll, comprising a cylindrical piston section intended to be guided in a cylinder bore of a stationary support, a contact or shoe section intended to bear against the inner surface of a roll shell rotatable about the support, and a contact or bearing surface in the form of a section of a cylinder surface where there are formed at least three hydrostatic bearing pockets. The bearing pockets flow communicate by channels with a surface of the piston section located in a cylinder chamber of the related cylinder bore. At least one of the channels possesses at least one portion which extends from a peripheral surface or region of the piston section at an inclination with respect to the lengthwise axis of such piston section closer to such axis. The mouth of the channel portion at the peripheral surface or region of the piston section is located near to the location which is essentially furthest from the plane of the axes of the contact or bearing surface and the piston section.
