    摘要: A method for producing a fiber web (W) in which method the fiber web (W) is calendered in at least one nip (NA) of a calender (20A). The fiber web (W) is cooled at least partially by moisturizing evaporating cooling by a moisturizing evaporating cooling unit (10) before the fiber web is calendered and moisture is absorbed during 10-500 ms. A production line for producing fiber webs (W) has a calender (20A) with a calendering nip (NA). The production line for fiber webs, in particular board webs, has a fiber web machine (50), in particular a board machine, with a head box, a wire section, a press section and a drying section, and at least one moisturizing evaporating cooling module (10), and a hard nip calender (20A) with a thermo roll, which has a surface temperature at least 120° C., and a reel-up (40).
