    Abstract: A roll, such as a filled calender roll of the type used in supercalenders of paper machines, includes an inner shaft and an outer shell which coaxially surrounds the inner shaft and is rotatable with respect thereto. A pair of deflection-compensating structures are provided to act between the shaft and the shell so as to urge the latter outwardly from the shaft at a pair of locations which are situated at different angular positions with respect to the common axis of the shell and shaft. The two deflection-compensating structures provide for compensation for the weight of the entire roll as well as for compensation for pressure acting on the roll at a nip which is defined in part by the roll.
