The first and second spray nozzle axes (FA, SA) are arranged on the same side of a plane (P) in which the web (W) is run. Each spray nozzle (10A, 11A) has an elongated spray opening configured to spray fluid in a direction towards the web (W). The first spray nozzle opening of the first group of spray nozzles (10A) has an inclination angle which differs from the second nozzle opening inclination angle of the second group of spray nozzles (11A).
