ABSTRACT:
A roll assembly for use in calenders has a non-rotatable carrier which is surrounded by a rotatable and radially movable hollow cylindrical shell. At least one end of the shell is driven by a pair of gears one of which is mounted in an annular bearing member surrounding a portion of the carrier and the other of which is connected with the one end of the shell. The bearing member shares the radial movements of the shell relative to the carrier. To this end, the radial position of the shell is monitored by one or two sensors in the form of first cylinder and piston units, and the bearing member is adjustable by two second cylinder and piston units. The cylinder chamber of each first unit is connected in circuit with the cylinder chamber of a different second unit, and the ratio of cross-sectional areas of the pistons of the first units to the cross-sectional areas of pistons of the second units is selected in such a way that the radial displacement of the bearing member matches or approximates the radial displacement of the shell. This prevents the application of pronounced stresses to the gears. The fluid in the two circuits is maintained above atmospheric pressure.
