Abstract

Beim Vorhangbeschichten eines bewegten Trägers mit einer flüssigen Beschichtungszusammensetzung führt die vom Träger mitgeführte Luft zur Verminderung der Beschichtungsqualität. Eine Abschirmvorrichtung die die Kontaktlinienströmung des frei fallenden Flüssigkeitsvorhangs beeinflußt, vermindert den Einfluß der vom Träger mitgeführten Luft.

Figure 00000001
When curtain coating a moving support with a liquid coating composition, the air carried by the support reduces the coating quality. A shielding device which influences the contact line flow of the freely falling liquid curtain reduces the influence of the air carried by the carrier.
