METHOD AND ARRANGEMENT FOR CONTROLLING MOISTURE IN A MULTIROLL CALENDER
A method and an arrangement for controlling evaporation and moisture in a multinip calender (10) when a continuous fibrous web (W) is calendered in calendering nips (1, 2, 3, 4, 5) placed one after the other before the fibro us web is wound on a reel-up/winder (9). It is characteristic of the invention that, 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 (10) change, the web is passed in the calender from the outlet of at least o ne nip into an air-float chamber (20) of the turning airborne type.
