Description

Vorrichtung zum gleichmäßigen Auftragen einer Beschichtungs­ masse auf eine Beschichtungswalze. An der Oberfläche der Walze (1) ist ein an den Walzenenden dicht geschlossener Raum (3) gebildet, dem die Masse durch (2) unter Druck zugeführt wird. Der Raum (3) ist durch Rakel (4, 5) an die Walzen­ oberfläche angeschlossen, die zu dem Raum (3) hin ange­ stellt sind. Der Druck im Raum (3) ist so eingestellt, daß Eintritt von Luft am Rakel (5) unterbunden wird und eher so­ gar dort ein Teil der Masse entgegen der Laufrichtung der Walzenoberfläche austritt zum Raum (9) hin, von wo die Masse zum Stutzen (10) entfernt wird. Der hohe Druck im Raum (3) verhindert nicht nur den Eintritt von Luft in den Massenzuführungsbereich, sondern führt auch zu kräftiger Druckströmung unter den Rakeln (4, 5) zum Zwecke verstärkten Massenaustauschs, Vertreibung von dort sitzenden Mikro­ blasen und guter Haschurenfüllung.Device for uniformly applying a coating composition to a coating roller. On the surface of the roller ( 1 ), a space ( 3 ) is formed which is tightly closed at the roller ends and to which the mass is fed through ( 2 ) under pressure. The space ( 3 ) is connected by squeegees ( 4 , 5 ) to the surface of the rollers, which are placed in the space ( 3 ). The pressure in the room ( 3 ) is set so that entry of air at the doctor blade ( 5 ) is prevented and part of the mass escapes towards the direction of the roll surface towards the room ( 9 ) from where the mass is used to support the nozzle ( 10 ) is removed. The high pressure in the room ( 3 ) not only prevents the entry of air into the mass supply area, but also leads to vigorous pressure flow under the doctor blades ( 4 , 5 ) for the purpose of increased mass exchange, displacement of microbubbles located there and good hash filling.

Der an das Rakel (4) in Drehrichtung sich anschließende Raum (7) ist mindestens bis zu dem sich anschließenden Rakel (8) mit Masse gefüllt. Die Überschußmasse wird bei (6) abge­ führt. Vor dem Rakel (8) herrscht kein Überdruck. Die Rakel (8) ist so positiv angestellt, daß sie keine wesentliche Druckdifferenz erzeugt. Die durch die vorgeordnete Rakelanordnung überfüllte Haschur kann hier ordnungsgemäß gleichmäßig abgerakelt werden.The space ( 7 ) adjoining the doctor blade ( 4 ) in the direction of rotation is filled with mass at least up to the adjoining doctor blade ( 8 ). The excess mass is abge at ( 6 ). There is no overpressure in front of the squeegee ( 8 ). The squeegee ( 8 ) is positioned so positively that it does not produce a significant pressure difference. The hash overfilled by the upstream squeegee arrangement can be scraped off properly and evenly here.

Claims (4)

1. Massenzufuhr in Druckraum, der entgegen und mit Laufrichtung durch zwei Rakel abgegrenzt ist.1. Mass supply in the pressure chamber, the opposite and with the direction of rotation is delimited by two squeegees. 2. Druck so hoch, daß durch davor liegendes Rakel keine Luft eingezogen wird.2. Pressure so high that no squeegee in front of it Air is drawn in. 3. Druck so groß, daß auch durch den davor liegenden Rakel­ spalt Masse austritt.3. Pressure so large that also through the doctor blade in front of it gap mass emerges. 4. Zwischen diesem Druckraum und einem nachgeschalteten Rakel (8) druckfreier, massegefüllter Zwischenraum.4. Between this pressure chamber and a downstream doctor blade ( 8 ) pressure-free, mass-filled space.
