The invention relates to an arrangement for closing the roll nips (N) in a multi-roll calender (1), in which the calender consists of one or several sets of rolls (2) attached to one or several frames (7) so that each set of rolls has at least three rolls, and that at least the first roll (3; 31) and the last roll (3; 32) in the set of rolls are provided with equipment, with which their casing can be moved to the direction of the intermediate rolls (4) in the said set of rolls. In the arrangement, the first roll (3; 31) and the last roll (3; 32) are fixedly attached, at least one of the intermediate rolls (4) in the set of rolls is fixedly attached, and the other intermediate rolls are provided with lightening elements for lightening the auxiliary means related to the intermediate rolls. In the arrangement, the roll nips (N) in the set of rolls (2) are closed so that the roll nips between the first roll (3; 31) and the fixed intermediate roll, the roll nip between the first roll and the fixed intermediate roll included, are closed by moving the first roll in the set of rolls in the direction parallel to the plane of the set of rolls towards the intermediate rolls (4), and the roll nips between the last roll (3; 32) and the fixed intermediate roll, the roll nip between the last roll and the fixed intermediate roll included, are closed by moving the last roll in the set of rolls in the direction parallel to the plane of the set of rolls towards the intermediate rolls (4).
