ABSTRACT:
The controlled deflection roll comprises a rotatable roll shell supported at a stationary support member by means of a plurality of hydrostatic pressure elements. The hydrostatic pressure elements are sealingly movably guided by guide structure, for example, bores, which define cylinder chambers. Each cylinder chamber is connected by a feed system comprising a feed channel to a source of a hydraulic pressure medium. Between each feed channel and the related hydrostatic pressure element, there is arranged a damping body provided with at least one throttle location, for example throttle bores, through which the hydraulic pressure medium can flow. The damping body defines essentially the only connection between the feed channel and the cylinder chamber. Possibly occurring oscillations or vibrations of the rotatable roll shell relative to the stationary support member are damped by these damping bodies and, accordingly, transmission of such oscillations or vibrations to the hydraulic pressure medium feed system is prevented.
