Abstract

Eine Vorrichtung 1 zum Erzeugen eines Unterdrucks an einer Antragsschicht auf einem bahnförmigen Trägermaterial 5, das über eine Beschichtungswalze 3 geführt ist, wird symmetrisch über zwei sich gegenüberliegende, stirnseitige Einströmöffnungen 13, 22 mit Druckluft beaufschlagt. Diese Druckluft wird symmetrisch über eine Verteilereinheit 23 der Vorrichtung 1 zugeführt. Diese Druckluft tritt über eine sogenannte Lavaldüse aus und erzeugt dabei oberhalb dieser Lavaldüse einen Unterdruck, der auf den Meniskus der Antragsschicht, beim Übergang aus dem Spalt der Beschichtungsdüse auf das Trägermaterial 4 einwirkt. In der Vorrichtung 1 sind verschiebbare Abdichtungen 27 vorgesehen, die es ermöglichen, die Breite der Düse an die Beschichtungsbreite des Trägermaterial 4 anzupassen.
