Abstract

Die Erfindung betrifft eine Walze mit einem drehbarenWalzenmantel und einer Reihe Stützelemente, die stationär undbiegesteif innerhalb des Walzenmantels angebracht sind. DieStützelemente sind einzeln oder gruppenweise gesteuert mittelshydraulischem Arbeitsdruck gegen den Walzenmantel vorspannbar,um dessen Form örtlich zu beeinflussen. Weiterhin sindVentileinrichtungen zur Steuerung des hydraulischen Drucks inden Stützelementen sowohl in der Walze als auch benachbart zuoder an dem jeweils zu steuernden Stützelement oder der Gruppeder jeweils zu steuernden Stützelemente angebracht.The invention relates to a roll having a rotatable roll shell and a series of support elements fixedly and rigidly mounted within the roll shell. The support elements are individually or group controlled by means of hydraulic working pressure against the roll shell biased to locally influence the shape. Further, valve means for controlling the hydraulic pressure in the support members are mounted both in the roller and adjacent to or on the support member to be controlled or the group of support members to be controlled respectively.
