Calender apparatus for paper or the like adapted to be directly associated with a paper machine and to operate as an on-machine supercalender includes a plurality of hard calendering rolls arranged over one another so as to form a stack of hard rolls and a plurality of soft calendering rolls adapted to define a series of soft supercalender nips with the hard rolls. The hard and soft rolls are mounted on drivable support apparatus whereby the hard nips defined by the hard rolls can be opened and the soft supercalender nips closed in order to accomplish supercalendering operation on a web passing through the apparatus.
