Abstract

Die Erfindung betrifft eine Streichvorrichtung für den mehrschichtigen Auftrag von Streichmedien, insbesondere Streichfarbe auf die Oberfläche einer laufenden Bahn, insbesondere einer Streichrohpapierbahn, umfassend:
- eine Mehrzahl von in beliebigem Abstand zueinander angeordneten Vorhangstreichköpfen (11, 12), die jeweils das Streichmedium (ta; tb) nach unten abgeben;
- eine Schrägführung (gp) auf welcher in Reihenfolge der von jedem der vorgenannten Mehrzahl von Vorhangstreichköpfen (11, 12) abgegebenen Streichmedien eine mehrschichtige Auftragsschicht ausgebildet wird.The invention relates to a coating device for the multilayer application of spreadable media, in particular coating color to the surface of a moving web, in particular a coated base paper web, comprising:
- A plurality of spaced apart at any distance Vorhangstreichköpfen (11, 12), each of the coating medium (ta; tb) deliver down;
a slanted guide (gp) on which a multilayer coating layer is formed in order of the spreadable media discharged from each of the aforementioned plurality of curtain coating heads (11, 12).

Erfindungsgemäß ist eine bewegliche Führung (cg) vorgesehen, die entlang einer gekrümmten Kante (gp1) der Schrägführung (gp) angeordnet ist und die die Bewegungsrichtung der mehrschichtigen Auftragsschicht von der Schrägführung (gp) in Richtung auf die Oberfläche der Bahn (W) unter Ausbildung eines sich bewegenden und sich auf die Bahnoberfläche auflegenden Vorhangs (tc) lenkt.

Figure imgaf001
According to the invention, a movable guide (cg) is provided, which is arranged along a curved edge (gp1) of the inclined guide (gp) and the direction of movement of the multilayer coating layer of the inclined guide (gp) towards the surface of the web (W) with training a moving and resting on the web surface curtain (tc) directs.
