A working roller for applying pressure to a web of material interposed between the working roller and an opposing working surface includes a generally tubular roll-shell with bearings at each end thereof, a pair of stationary journals for supporting the roll-shell for rotation about its longitudinal axis, a stationary internal support structure, and a plurality of internal rollers which bear upon the inner wall of the roll-shell and are mounted to the internal support structure by a plurality of individually adjustable thrust-supports for controlling the outer contours of the roll-shell. The invention allows greater control of the outer contours of the roll-shell to compensate for localized, longitudinally asymmetrical deviations from the desired pressure distribution or spacing between the working roller and an opposing working surface or to permit predetermined, non-uniform pressure distributions or spacings between the working roller and an opposing working surface. |
