Abstract

Bei einem Verfahren zum Besprühen einer bewegten Faserstoffbahn 12, insbesondere Papier- oder Kartonbahn, mittels wenigstens einer Düse 14 wird der Düse 14 ein vorzugsweise einstellbarer Volumenstrom des betreffenden Sprühmediums 16 über wenigstens ein Ventil 20 zugeführt, wobei im Volumenstrom des Sprühmediums 16 auftretende Pulsationen vorzugsweise gedämpft oder abgeschwächt werden. Es wird auch eine entsprechende, eine Düse 14 sowie wenigstens ein Ventil 20 umfassende Vorrichtung beschrieben.

Figure 00000001
In a method for spraying a moving fibrous web 12, in particular paper or cardboard web, by means of at least one nozzle 14, a preferably adjustable volume flow of the relevant spray medium 16 is fed to the nozzle 14 via at least one valve 20, pulsations occurring in the volume flow of the spray medium 16 preferably being damped or be weakened. A corresponding device comprising a nozzle 14 and at least one valve 20 is also described.
