Method in calendering of a paper web in which the paper web is conveyed through a calendering nip formed by two calender rolls, at least one of which is a soft-faced roll having a coating of a resilient or polymeric material, or over which a belt of resilient or polymeric material is directed and passed through the nip. The profile of the calendering nip is controlled to compensate for defects in the web entering the calender. The profile control is accomplished by changing the diameter of the soft-faced roll zonewise by a profile control device arranged inside the body and performing temperature profiling. The profile control device include temperature control elements such as heating elements located in zones for heating a heat transfer medium such as air supplied into the body.
