An on-machine calender intended to be on-line connected to a paper machine. The calender comprises a number of subsequent calendering nips, through which the web (W) to be calendered can be passed. The nips are formed between a soft calender roll and a hard calender roll or between two soft calender rolls. The calender is composed of one or several, for example two, subsequent calender modules (M1,M2). The modules comprise one counter-roll (10,20) and at least two soft calendering rolls (11,12,13;21,22, 23), which are placed at both sides of the counter-roll (10,20) in the direction of running of the web (W). The calender rolls (10,11,12,13;20,21, 22,23) are displaceable in relation to each other so that the threading of the web (W) can be carried out as a straight run, for which purpose an open passage is opened through the calender.
