Abstract

Die Erfindung betrifft eine Vorhangstreichmaschine (1) zur Beschichtung einer laufenden Papier-, Karton oder anderen Faserstoffbahn (w), aufweisend einen ersten Vorhangkopf (1a) und einen zweiten Vorhangkopf (1b) sowie aufweisend eine schräg gestellte Führungsplatte (2), welche unterhalb der Vorhangköpfe (1a,1b) angeordnet ist und die die von den Vorhangköpfen abgegebenen Vorhangschichten aufnimmt und entlang ihrer Schräge (2a) herabfließen lässt, wobei die Vorhangschichten (ca, cb) von einer Vorhangführung (2b) aus auf die Oberfläche der zu beschichtenden Bahn (w) in Form eines Vorhangs (c) fallen.The invention relates to a curtain coater (1) for coating a running paper, board or other fibrous web (w), comprising a first curtain head (1a) and a second curtain head (1b) and having an inclined guide plate (2), which below the Curtain heads (1a, 1b) is arranged and which receives the curtain layers emitted by the curtain heads and flows along its slope (2a), wherein the curtain layers (ca, cb) from a curtain guide (2b) on the surface of the web to be coated ( w) fall in the form of a curtain (c).

Erfindungsgemäß ist vorgesehen, dass eine Vorrichtung (9) zur Einstellung der Auftragsbreite für die erste Vorhangschicht (ca) vorgesehen ist, welche so angeordnet ist, dass sie sich unterhalb des ersten Vorhangkopfs (1a) für die erste Schicht (ca, sa) befindet und dem seitlichen oberen Bereich der Führungsplatte (2) zugeordnet ist, so dass ein mittlerer Teil (tac) der ersten Vorhangschicht (ca), welche vom Vorhangkopf (1a) abgegeben wird von seitlichen Teilen (tae) derselben Schicht (ca) abtrennbar ist, wodurch der mittlere Teil (tac) auf der Oberfläche der Führungsplatte (2) hinabgleitet und die seitlichen Teile (tae) in entgegen gesetzter Richtung wie der Fluss des mittleren Teils (tac) abfließen.

Figure imgaf001
According to the invention, provision is made for a device (9) for setting the application width for the first curtain layer (ca), which is arranged so that it is located below the first curtain head (1a) for the first layer (ca, sa) and is associated with the lateral upper portion of the guide plate (2), so that a central part (tac) of the first curtain layer (ca), which is discharged from the curtain head (1a) of lateral parts (tae) of the same layer (ca) is separable, whereby the middle part (tac) slides down on the surface of the guide plate (2) and the lateral parts (tae) flow away in the opposite direction as the flow of the middle part (tac).
