The invention concerns a calender, in particular a supercalender, on whose frame (1) a set of rolls (2) is mounted, which comprises an upper roll (3), a lower roll (4), and several intermediate rolls (5) placed between the upper roll and the lower roll. The rolls (3, 4, 5) are supported on the frame (1) by the intermediate structure of the base parts (34, 47, 54) being vertically displaceable along guides (7) provided in the frame. Of the base parts, at least the base parts (54) of the intermediate rolls can be positioned in the vertical direction by means of lifting spindles (6) provided in the frame (1) and by means of spindle nuts (56) provided on the spindle. The base parts (54) of the intermediate rolls are supported on the lifting spindles (6) being vertically displaceable by means of pressure-medium operated relief devices (57) arranged between the base parts (54) and the spindle nuts (56) to reduce the journal loads on the rolls (5). The bearing housings (51) of the intermediate rolls are attached to the base parts (54) being pivotable relative to an articulation shaft (53) parallel to the axes of the rolls (3, 4, 5) and supported on the base parts (54) by means of attenuation devices (10) to equalize the forces resulting from movements of the nips (N1, N2, N3, N4) between the rolls and to attenuate oscillations of the rolls (5).
