Abstract: 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).

Abstract: The invention concerns an equipment in the system of rolls in a supercalender for equalizing the profiles of linear loads between the rolls. In the normal way, the system of rolls comprises an upper roll, a lower roll, several intermediate rolls placed between the upper roll and the lower roll, as well as lifting spindles (40) placed at both sides of the system of rolls. The equipment in accordance with the invention comprises lightening devices (10) acting upon the bearing housing (38) at each end of at least one roll, the lightening devices being arranged to eliminate the distortions caused by the weight of the bearing housings (38) and the auxiliary devices attached to same in the lateral areas of the profiles of linear load between the rolls.
