Abstract
A sag-compensating roll comprises a roll shell rotatable about a support beam with hydrostatic support means therebetween. The ends of the beam are supported in casings at each end of the roll. End sections of the roll shell are rotatably mounted in pivotally mounted arms in the casings which pivot about an axis spaced from the roll axis. Couplings between the end sections and the central portion of the roll shell provide centering while allowing pivoting movement therebetween. A drive shaft in one housing is coaxial with the pivot axis and drives the corresponding end section through a transmission. A drive motor is mounted on the casing. Three mutually perpendicular exterior surfaces of the casings permit assembly of a plurality of rolls to form a calender.
