Zusammenfassung:	The invention relates to a method and a system for applying at least one substance layer (C) in form of foam onto a moving fiber web (W) through at least one opening of at least one nozzle (15) of an application unit. The substance (C) is flown from the nozzle opening (15) onto a guide surface (20), which guide surface (20) the substance is flown onto a target surface and one end of the guide surface (15) is located in contact with the target surface, onto which the substance is applied. Keksinnön kohteena on menetelmä ja järjestelmä ainakin yhden ainekerroksen (C) applikoimiseksi liikkuvalle kuiturainalle (W) vaahdon muodossa applikointiyksikön ainakin yhden suuttimen (15) ainakin yhden aukon kautta. Aine (C) virtautetaan suuttimen (15) aukosta ohjauspinnalle (20), jolla ohjauspinnalla (20) aine virtautetaan kohdepinnalle ja ohjauspinnan (15) yksi pää on sijoitettu kosketukseen kohdepinnan, jolle aine applikoidaan, kanssa.
