ABSTRACT:
A deflection adjusted roll includes a plurality of hydraulic support elements for a roll jacket, wherein the support elements are provided with a hydraulic pressure medium via a bore axially extending in common with the carrier as well as via further radial bores discharging into the axially extending bore, with the radial bores being in communication with the support elements and separate pressure control of the pressure medium for each support element being achieved in that each one of the radially extending bores is associated with a controllable throttling element, with the throttling element being slidably disposed within the axially extending bore and so shaped and pressed against the inside surface of the axial bore that at least one connecting gap is provided or available between the axial bore and the radial bores, whereby the through-flow quantity of the hydraulic pressure medium is controllable via the cross section of the connecting gap.
