Abstract

This publication discloses a slide bearing (16) for mounting and rotating a calender roll (11, 12, 13, 14) by means of the bearing. The slide bearing at both ends of the roll comprises slide surfaces (24a) for supporting the roll on two opposite sides, and a bearing body (21), and additionally displacing members (23, 26) disposed between the bearing body (21) and the slide surfaces for opening, closing or loading a roll nip. The displacing members (23, 26) comprise stroking actuating members (23). Control of forces in each individual nip is easy in the slide bearing system (16) of the multi-roll calender disclosed in the publication. By means of the multi-roll calender and the method of the publication, the nips of the multi-roll calender can be closed, opened or loaded in a versatile manner, also in different directions, without needing to use control devices, such as loading arms, placed outside the bearing systems of rolls.
