Abstract

Beim Verfahren zur Vorhangbeschichtung eines bewegten Trägers mit photographischen Emulsionen wird die Giesslösung oberhalb der Giesserlippe (4) durch Seitenbegrenzungsplatten (2) derart geführt, dass deren beiden Ränder unter der Einwirkung der Oberflächenspannung an den Seiten der Seitenbegrenzungsplatten (2) nicht steigen.In the process of coating a moving curtain The casting solution becomes a support with photographic emulsions above the pouring lip (4) through side limitation plates (2) guided so that the two edges under the Effect of surface tension on the sides of the Do not climb the side limit plates (2).

Bei der Vorrichtung zur Durchführung des Verfahrens mit Giesserplatten (1) und einer bogenförmigen Giesserfrontplatte, die in die Giesserlippe (4) mündet und beidseitig angebrachten Seitenbegrenzungsplatten (2), weist die begrenzende Kante (25) der Seitenbegrenzungsplatten (2) eine Schneide (24) auf, dessen beiden Schenkel einen Winkel von 10 - 80°, vorzugsweise 60°, einschliessen.With the device for performing the method with Foundry plates (1) and an arcuate Giesserfrontplatte, which opens into the Giesserlippe (4) and side limiting plates (2) attached on both sides the delimiting edge (25) of the side delimitation plates (2) a cutting edge (24), the two legs of which form an angle from 10 - 80 °, preferably 60 °.

Ein solches Verfahren und eine derartige Vorrichtung ermöglichen eine gleichmässige Beschichtung, ohne Schichtdickenfehler.
