The application roller 18 is Height-adjustable in the frame 8 to the order gap 19 between them Lateral surface and the web 1 supported in this area by the counter roller 4 to be able to adjust. On the lower side facing away from the counter roller 4, the Applicator roller 18 in an ink chamber 20, which is continuously supplied with coating color becomes. On the web entry side one of the outer surface of the applicator roller 18 is adapted curved baffle 21 arranged up to the area of the application gap 19th is sufficient and forms a narrow ink supply channel with the application roller 18. By the The coating material is fed into the ink supply channel in such a large amount on the web 1 introduced that an excess 22 runs back over the back of the baffle 21. The excess 22 is collected in a tub 23 and like that amount scraped back from doctor blade 12. All of the above Parts of the application system 2 are stored in the frame 8 and can therefore can be exchanged with this for another order system 2.

In den Figuren 2 bis 5 sind Beschichtungsvorrichtungen beschrieben, bei denen andere Auftragsysteme 2 eingesetzt sind. Die übrigen Teile der Beschichtungsvorrichtungen (Gegenwalze 4 mit ihrem Gestell 5, Dosiersystem 3) sind übereinstimmend zu dem Ausführungsbeispiel nach Figur 1 aufgebaut.In Figures 2 to 5 coating devices are described in which other application systems 2 are used. The remaining parts of the coating devices (Counter roller 4 with its frame 5, metering system 3) are the same built to the embodiment of Figure 1.

Bei der Ausführungsform nach Figur 2 enthält das Auftragsystem 2 eine zur Gegenwalze hin offene Auftragkammer 24, die aus einer Farbkammer 25 mit Streichfarbe versorgt wird. Die Auftragkammer 24 ist an der Bahnauslaufseite mit einem über die Arbeitsbreite reichenden drehbar gelagerten Stab 26 abgeschlossen, der zur von der Gegenwalze 4 abgestützten Bahn 1 einen Vordosierspalt offen läßt, durch den ein Überschußfilm gewünschter Dicke erzeugt wird. An der Einlaufseite der Bahn 1 bleibt ein Überlaufspalt 27 offen, durch den überlaufende Streichfarbe 28 austritt und in einer Wanne 29 aufgefangen wird. Dies gewährleistet eine vollständige Benetzung der Bahn 1 ohne unbedeckte Stellen. Um die Menge der der Auftragkammer 24 zugeführten Streichfarbe regulieren zu können, ist zwischen der Farbkammer 25 und der Auftragkammer 24 eine verstellbare Leiste 30 angeordnet, mit der sich der Querschnitt der Einlaßöffnung in die Auftragkammer 24 verändern läßt. Alle vorstehenden Teile des Auftragsystems 2 sind ebenso wie eine Auffangwanne 31 für die vom Dosiersystem 3 abgerakelte Streichfarbe an einer Quertraverse 32 befestigt, die in den Seitenteilen 9 des Gestells 8 schwenkbar gelagert ist. Sie können so als Gesamtes ausgewechselt werden. Die Schwenkbarkeit der Traverse 32 ermöglicht ein Absenken des Auftragsystems 2 von Arbeitsposition an einer Gegenwalze in eine Position, in der das System 2 gereinigt oder eine neue Bahn 1 eingezogen werden kann.In the embodiment according to FIG. 2, the application system 2 contains one for the counter roller open application chamber 24, which consists of a paint chamber 25 with coating color is supplied. The application chamber 24 is on the web exit side with a Working width-reaching rotatably mounted rod 26 completed to the of the Counter roll 4 supported web 1 leaves a pre-metering gap through which a Excess film of desired thickness is generated. Remains on the entry side of lane 1 an overflow gap 27 open, through which overflowing coating 28 emerges and in a tub 29 is collected. This ensures complete wetting the web 1 without uncovered places. By the amount supplied to the application chamber 24 To be able to regulate coating color is between the ink chamber 25 and the application chamber 24 an adjustable bar 30 is arranged, with which the cross section can change the inlet opening in the application chamber 24. All of the above parts of the application system 2 are as well as a sump 31 for the dosing system 3 doctored coating color attached to a crossbar 32, which in the Side parts 9 of the frame 8 is pivotally mounted. You can do so as a whole be replaced. The pivotability of the traverse 32 enables lowering the application system 2 from working position on a counter roller in a Position in which system 2 is cleaned or a new web 1 is drawn in can.

Die Figuren 3 bis 5 zeigen Beschichtungsvorrichtungen, bei denen das Auftragsystem 2 eine eigene Gegenwalze 33 enthält, von der die Bahn 1 beim Auftragen abgestützt wird. Zwischen dem Auftragen und dem Dosieren wird die Bahn über eine gewisse Strecke geradlinig geführt. Die geradlinige Führung der Bahn 1 mit dem Überschußauftrag bis zum Dosieren hat den Vorteil, daß die auf den Überschuß einwirkenden Zentrifugalkräfte minimiert werden. Zu große Zentrifugalkräfte können zum Abspritzen von Streichfarbe und/oder zu Ungleichmäßigkeiten im Überschußfilm führen, die beim Dosieren nicht mehr ausgeglichen werden.Figures 3 to 5 show coating devices in which the application system 2 contains its own counter roller 33, from which the web 1 is supported during application becomes. Between the application and the dosing the web is over a certain The route is straight. The straightforward guidance of web 1 with the excess order until dosing has the advantage that those acting on the excess Centrifugal forces can be minimized. Centrifugal forces that are too high can cause spraying of coating color and / or lead to irregularities in the excess film, which are no longer balanced during dosing.

Bevorzugt ist das die Streichfarbe auf die Bahn 1 auftragende Element des Auftragsystems 2 am Ende des Umschlingungsbereichs der Gegenwalze 33 angeordnet, damit die Bahn 1 mit dem Überschußauftrag ohne oder mit möglichst geringer Krümmung geradlinig bis zum Dosierelement (Schabermesser 12) des Dosiersystems 3 verläuft. Aus dem gleichen Grunde ist auch das Dosierelement möglichst nahe an der Auflauflinie der Bahn 1 auf die Gegenwalze 4 angeordnet.The element of the application system that applies the coating color to the web 1 is preferred 2 arranged at the end of the wrapping area of the counter roller 33, thus the web 1 with the excess order without or with as little as possible Straight curve up to the dosing element (scraper knife 12) of the dosing system 3 runs. For the same reason, the dosing element is as close as possible the run-up line of the web 1 arranged on the counter roller 4.

Das Ausführungsbeispiel nach Figur 3 enthält als Auftragsystem 2 ein Walzenauftragwerk, das bereits beim Ausführungsbeispiel nach Figur 1 beschrieben wurde. Der einzige Unterschied besteht darin, daß das Auftragsystem 2 eine eigene Gegenwalze 33 aufweist, die im Gestell 8 gelagert ist und somit mit ausgetauscht werden kann. Die angetriebene Gegenwalze 33 bildet mit der Auftragwalze 18 den Auftragspalt 19, in dem die Streichfarbe im Überschuß auf die Bahn 1 aufgetragen wird. The exemplary embodiment according to FIG. 3 contains a roller application unit as application system 2, that has already been described in the embodiment of Figure 1. The the only difference is that the application system 2 has its own counter roller 33, which is mounted in the frame 8 and can therefore be replaced. The driven counter roller 33 forms the application gap 19 with the application roller 18, in which the coating color is applied in excess to the web 1.

Bei der Ausführungsform nach Figur 4 wird ein Auftragsystem 2 mit einer Auftragkammer 24 eingesetzt, die an der getrennten Gegenwalze 33 des Auftragsystems 2 angeordnet ist. Der Auftragkammer 24 wird Streichfarbe unter Druck zugeführt und so an die von der Gegenwalze 33 abgestützte Bahn 1 übergeben.In the embodiment according to FIG. 4, an application system 2 with an application chamber 24 used on the separate counter roller 33 of the application system 2 is arranged. The application chamber 24 is supplied with coating ink under pressure and thus passed to the web 1 supported by the counter roller 33.

Die Figur 5 zeigt eine Ausführungsform eines Auftragsystems 2 mit einer Schlitzdüse 34, aus der die Streichfarbe gegen die Bahn 1 gespritzt wird. Die Schlitzdüse 34 wird aus einer Farbkammer 25 versorgt, deren Austrittsquerschnitt mittels einer verstellbaren Leiste 35 verstellbar ist. Es wird genau die gewünschte Überschußmenge auf die Bahn 1 aufgetragen, wobei die Auftragsmenge über die Pumpenleistung der zufördernden Pumpe einstellbar ist. Auch bei dieser Ausführungsform weist das Auftragsystem 2 eine eigene, im Gestell 8 gelagerte und angetriebene Gegenwalze 33 auf, die von der Bahn 1 teilweise umschlungen wird und so diese beim Auftragen abstützt. Die Düse 34 ist ebenfalls am Ende des Umschlingungsbereichs der Gegenwalze 33 angeordnet, damit die Bahn 1 mit dem Überschußauftrag möglichst geradlinig zum Dosiersystem 3 verläuft.FIG. 5 shows an embodiment of an application system 2 with a slot nozzle 34, from which the coating color is sprayed against the web 1.
