ABSTRACT:
An adjustable deflection roll includes a fixed support having a center axial bore. A roll is rotatably mounted about the fixed support. The roll sleeve is supported on support elements. The support elements are actuated by a pressure fluid. The support elements form a plurality of pressure zones. Each of the pressure zones are independently fed with pressure fluid at an independent predetermined pressure by feeder tubes which are disposed in the center axial bore of the fixed support. The feeder tubes are connected to supply lines at one axial end of the fixed support. A plurality of divider walls are disposed in the bore to separate the sections of the bore into the plurality of pressure zones. At least one of the plurality of feeder tubes has an opening in each of the plurality of zones. Each of the plurality of divider walls is formed by at least two disks, which are axially spaced apart at a predetermined distance from each other. The plurality of feeder tubes pass through the at least two disks. The at least two disks fix a position of each of the plurality of feeder tubes. A space disposed between each of the at least two disks is filled, in a pressure-tight manner, with a casting compound.
