Abstract

The present invention relates to a calendering arrangement for a paper machine for producing higher-gloss paper grades, in particular paper grades with a Hunter gloss % above 40. In accordance with the invention, the arrangement comprises, as a combination, pairs of calendering units (1, 3) disposed in the machine direction one after the other and apart from one another, which pairs are each formed of separate and different calendering units (1, 3) and in each of which the nip load in the latter calendering unit (3) is higher than the nip load in the preceding calendering unit (1).
Advantageously, the calendering unit (1) placed first in the machine direction is an on-line long-nip calendering unit (1) and the calendering unit (3) placed after that in the machine direction is an on-line or off-line supercalender.
