A cooler () providing gas blows and comprising at least one cooler module having at least one cooler module () of the cooler () is curved to provide a gas turn module for turning run of the fiber web (W) from its main running direction 80-190&#xb0;. The cooler () includes moisturizing at least one surface of the fiber web. Having a blowing zone () in which gas is blown toward a surface of the fiber web and that the cooler comprises at least one suction zone (), in which the fiber web evaporated moisture is drawn away from the proximity of a surface of the fiber web. There are cooler modules on both sides of the fiber web. The cooler has a gas turn module located inside a curved fiber web run, which provides gas blows toward the curved fiber web during the run.

Production line for producing fiber webs and a cooler

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 (A). The fiber web (W) is cooled at least partially by moisturizing evaporating cooling by a moisturizing evaporating cooling unit () 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 (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&#xb0; C., and a reel-up ().

Method for producing fiber webs and production line for producing fiber webs

A device for drying and treating a fiber-based moving fiber web () in a machine intended for producing tissue paper includes a metal belt () which is arranged to support the fiber web () and to transfer the fiber web () in the machine direction and which metal belt () is arranged as a continuous rotating cycle, at least one roll () the shell of which is in contact with the metal belt () arranged to rotate around, which roll () is for supporting and/or controlling the metal belt (), and at least one counter element () arranged to create a contact area outside the metal belt () between the metal belt () and the counter element () for a process zone (), via which process zone () the fiber web () is arranged to travel when using the device.
