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. The lightening devices (10) are provided between brackets (39) or equivalent attached to the bearing housings of the roll and spindle nuts (44) mounted on the lifting spindles (40) and placed underneath the brackets so as to lift the bearing housings (38) while resting on the spindle nuts (44).
