A production line for producing fiber webs (W) has a calender (A) with a calendering nip (NA). The production line for fiber webs, in particular board webs, has a fiber web machine (), 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 (), and a hard nip calender (A) with a thermo roll, which has a surface temperature at least 120° C., and a reel-up ().
