Abstract
A method and an arrangement for controlling evaporation and moisture in a multinip calender () when a continuous fibrous web (W) is calendered in calendering nips (_) placed one after the other before the fibrous web is wound on a reel-up/winder (). With a view to making the net evaporation from and the final moisture content of the web (W) constant when the running situations in the calender () change, the web is passed in the calender from the outlet of at least one nip into an air-float chamber () of the turning airborne type.
