Zusammenfassung:	The invention relates to an arrangement in of a coating or sizing section of a fiber web production line, in which section a treatment substance, in particular a coating or sizing medium, is applied onto the fiber web by spraying, which arrangement comprises nozzles (20A, 20B) located in one nozzle row (21) extending in cross-direction i.e. in width direction of the fiber web for spraying the treatment substance onto the fiber web. The arrangement comprises at least two distributor pipes (10A, 10B) connected to the nozzles (20A, 20B) for supplying treatment substance to the nozzles (20A, 20B) in the one nozzle row (21). The invention also relates to a method for a coating or sizing section of a fiber web production line, in which method a treatment substance, in particular a coating or sizing medium, is applied onto the fiber web by spraying by nozzles (20A, 20B) located in one nozzle row (21) extending in cross-direction i.e. in width direction of the fiber web for spraying the treatment substance onto the fiber web. In the method the treatment substance is supplied to the nozzles (20A, 20B) by at least two distributor pipes (10A, 10B).
