Abstract

This publication described a method for loading the bearings of an intermediate roll (13,14) of a multi-roll calender (100) and a multi-roll calender (100). The multi-roll calender comprises one or more sets of rolls (10) in which in at least one set of rolls the centre shafts (C14, C15) of at least two calender rolls form a nip plane (P), whereby for normal calendering a bottom roll (15) is loaded on the nip plane (P) by first load means, such as bottom cylinders (16). For partial nip run, in said at least one set of rolls (10) of the multi-roll calender (100) the centre shaft (C15) of the bottom roll (15) is transferred, without detaching from the multi-roll calender (100), aside from the plane (V14) passing via the centre shaft (C14) of the intermediate roll (14) above the bottom roll (15), and the bottom roll (15) is loaded against the intermediate roll (14) above it by second load means (18) at an angle α of 15-25°, advantageously at an angle α of about 22°, in relation to the vertical plane.
