The calender (1) according to the invention comprises at least a calender frame (2), and at least one roll assembly composed of at least three superimposed rolls (3a, 3b, 3c; 4a, 4b, 4c) comprising axles (7a, 7b, 7c; 8a, 8b, 8c). At least two (N1, N2, N3, N4,) nips that can be opened are formed between the rolls (3a, 3b, 3c; 4a, 4b, 4c) in the roll assembly. The roll assembly is arranged in the frame (2) of the calender (1) in such a manner that the centres of the axles (7a, 7b, 7c; 8a, 8b, 8) of the rolls (3a, 3b, 3c, 4a, 4b, 4c) are located substantially on the same line when seen from the side, when all the nips (N1, N2, N3, N4) are closed. The roll assembly is positioned in such an angle ( alpha ) with respect to the vertical direction that the vertical line drawn via the centre of the axle (7b, 7c; 8b, 8c) of any of the rolls (3b, 3c; 4b, 4c) travels past the axle (7a, 7b; 8a, 8b) of the roll (3a, 3b; 4a, 4b) above said roll (3b, 3c; 4b, 4c) and said angle ( alpha ) is 20 DEG at the most.
