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 Pulsationsventil 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 Pulsationsventil 20 umfassende Vorrichtung beschrieben.

Figure 00000001
In a method for spraying a moving fibrous web 12, in particular paper or board web, by means of at least one nozzle 14, the nozzle 14 is supplied with a preferably adjustable volumetric flow of the relevant spraying medium 16 via at least one pulsation valve 20, whereby pulsations occurring in the volume flow of the spraying medium 16 are preferably damped or weakened. A corresponding device comprising a nozzle 14 and at least one pulsation valve 20 will also be described.
