Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zum ein- oder beidseitigen Auftragen von mindestens zwei flüssigen bis pastösen Auftragsmedien auf eine laufende Oberfläche, aufweisend ein Vorhangauftragswerk zum Auftragen der Auftragsmedien, wobei das Vorhangauftragswerk die Auftragsmedien als sich im wesentlichen schwerkraftbedingt bewegende Vorhänge an die laufende Oberfläche abgibt, und die Oberfläche bei direktem Auftrag die Oberfläche einer Materialbahn, insbesondere aus Papier oder Karton, und bei indirektem Auftrag die Oberfläche eines Übertragungselementes, beispielsweise eine Auftragswalze ist, welches die Auftragsmedien auf die Oberfläche der Materialbahn überträgt.The invention relates to a device for applying one or both sides of at least two liquid to pasty application media to a running surface, comprising a curtain application unit for applying the application media, the curtain application unit delivering the application media to the current surface as curtains that move essentially due to gravity, and the surface in the case of direct application is the surface of a material web, in particular made of paper or cardboard, and in the case of indirect application the surface of a transfer element, for example an application roller, which transfers the application media to the surface of the material web.
Solche Vorhangauftragswerke, mit denen mehrere Auftragsmedien aufgebracht werden können, sind allgemein aus dem Stand der Technik bekannt. Bei diesen bekannten Vorhangauftragswerken werden die Auftragsmedien mit einer Wanne gemeinsam aufgefangen. Die Wanne ist zwischen dem Vorhangauftragswerk und der laufenden Oberfläche angeordnet, so dass sie beim Anfahren oder Abstellen desSuch curtain applicators, with which several application media can be applied, are generally known from the prior art. In these known curtain applicators, the application media are collected together with a tub. The trough is arranged between the curtain applicator and the running surface, so that when you start or stop the
Vorhangauftragswerks, oder zur Erzeugung von unbeschichteten Rändern auf der laufenden Oberfläche verwendet wird. Da die Auftragsmedien gemeinsam mit derCurtain applicator, or used to create uncoated edges on the running surface. Since the order media together with the
Wanne aufgefangen werden, vermischen sie sich in der Wanne. Deshalb können die teuren Auftragsmedien für eine weitere Beschichtung nicht mehr verwendet werden.Tub are caught, they mix in the tub. Therefore, the expensive application media can no longer be used for a further coating.
Eine Trennung der Auftragsmedien voneinander ist nur sehr aufwändig zu realisieren und somit teuer. Deshalb müssen die vermischten Auftragsmedien entsorgt werden, wodurch weitere hohe Kosten anfallen.Separating the order media from each other is very difficult and therefore expensive to implement. Therefore, the mixed application media must be disposed of, which incurs further high costs.
Die Erfindung hat die Aufgabe, eine Vorrichtung der eingangs genannten Art dahingehend zu verbessern, dass die Auftragsmedien zukünftig nach dem Auffangen jeweils wieder verwendet werden können, und nicht mehr entsorgt werden müssen. Die Erfindung löst die gestellte Aufgabe durch ein Vorhangauftragswerk der eingangs genannten Art, bei dem erfindungsgemäß zwischen dem Vorhangauftragswerk und der Materialbahn eine Auffangeinrichtung zum separaten Auffangen jedes Auftragsmediums vorgesehen ist, wobei das Vorhangauftragswerk und die Auffangeinrichtung relativ zueinander bewegbar sind. Da die Auffangeinrichtung die verschiedenen Auftragsmedien separat auffängt, können sich diese nicht mehr vermischen. Sie können deshalb für einen weiteren Beschichtungsvorgang wieder verwendet werden, und müssen nicht mehr entsorgt werden. Dadurch werden sowohl die hohen Anschaffungskosten für die Auftragsmedien reduziert, als auch die Entsorgungskosten eingespart.The object of the invention is to improve a device of the type mentioned at the outset in such a way that the application media can in each case be used again after collection, and no longer have to be disposed of. The invention solves this problem by a curtain applicator of the type mentioned, in which, according to the invention, a collecting device is provided between the curtain applicator and the material web for collecting each application medium separately, the curtain applicator and the collecting device being movable relative to one another. Since the collecting device collects the different application media separately, they can no longer mix. They can therefore be used for another coating process and do not have to be disposed of. As a result, both the high acquisition costs for the order media are reduced and the disposal costs are saved.
An der Auffangeinrichtung kann eine Ablaufeinrichtung angeordnet sein. Dann können die aufgefangenen Auftragsmedien von der Auffangeinrichtung abgeführt werden, um wieder erneut für den Beschichtungsvorgang zur Verfügung zu stehen.A drain device can be arranged on the collecting device. Then the collected application media can be removed from the collecting device in order to be available again for the coating process.
Um die Auftragsmedien von der Auffangeinrichtung an die Ablaufeinrichtung weiterleiten zu können, kann die Auffangeinrichtung mit Ablauföffnungen zur Weitergabe der Auftragsmedien an die Ablaufeinrichtung ausgestattet sein.In order to be able to forward the application media from the collecting device to the drain device, the collecting device can be equipped with drain openings for forwarding the application media to the drain device.
Wenn die Auffangeinrichtung oberhalb der Ablauföffnungen angeordnete Schrägen aufweist, können die Auftragsmedien über die Schrägen den Ablauföffnungen zugeleitet werden.If the collecting device has bevels arranged above the drain openings, the application media can be fed to the drain openings via the bevels.
Damit die Auftragsmedien von der Auffangeinrichtung separat aufgefangen werden können, kann die Auffangeinrichtung in mehrere zueinander benachbarte Abschnitte unterteilt sein, wobei jeder der Abschnitte nur ein Auftragsmedium aufnimmt.So that the application media can be collected separately by the collecting device, the collecting device can be subdivided into several adjacent sections, each of the sections receiving only one application medium.
Die zueinander benachbarten Abschnitte der Auffangeinrichtung können durch ein Trennelement voneinander getrennt sein. Somit ist sichergestellt, dass sich die verschiedenen Auftragsmedien nicht miteinander vermischen. Die Ablauföffnungen des einen Abschnittes sind zu den Schrägen des benachbarten Abschnittes benachbart. Dann kann das von einem der Abschnitte aufgenommene Auftragsmedium in den Ablauföffnungen dieses Abschnittes abfließen, und unter den zu den Ablauföffnungen benachbarten Schrägen des benachbarten Abschnittes hindurchfließen, um der Ablaufeinrichtung zugeführt zu werden. Die Schrägen erfüllen auf diese Weise eine weitere Funktion, indem sich durch sie verschiedene Auftragsmedien kreuzen können, ohne dass sich die kreuzenden Auftragsmedien miteinander vermischen.The mutually adjacent sections of the collecting device can be separated from one another by a separating element. This ensures that the different application media do not mix. The drainage openings of one section are adjacent to the slopes of the adjacent section. The application medium received by one of the sections can then flow off in the outlet openings of this section and flow under the bevels of the adjacent section adjacent to the outlet openings in order to be fed to the outlet device. In this way, the bevels fulfill a further function in that different application media can cross through them without the crossing application media mixing with one another.
Um die von der Auffangeinrichtung kommenden Auftragsmedien separat abführen zu können, kann die Ablaufeinrichtung ein Ablaufblech aufweisen, an dessen Ende für jedes Auftragsmedium eine separate Abführrinne angeordnet ist.In order to be able to discharge the application media coming from the collecting device separately, the discharge device can have a drain plate, at the end of which a separate discharge channel is arranged for each application medium.
Damit sich die verschiedenen Auftragsmedien nicht auf dem Ablaufblech miteinander vermischen können, kann das Ablaufblech für jedes Auftragsmedium mindestens eine separate Rinne aufweisen.So that the different application media cannot mix with each other on the drain plate, the drain plate can have at least one separate channel for each application medium.
Die Rinnen des Ablaufbleches können mindestens eine der nebeneinander liegenden Abführrinnen am Ende des Ablaufbleches überbrücken. Dann kreuzt eines der Auftragsmedien, das in der überbrückenden Rinne des Ablaufbleches geführt wird, beim Übergang vom Ablaufblech in die Abführrinne mindestens eines der anderen Auftragsmedien. Durch diese Kreuzung ist eine Vermischung der beiden Auftragsmedien sicher ausgeschlossen.The gutters of the drain plate can bridge at least one of the discharge channels lying next to each other at the end of the drain plate. Then one of the application media, which is guided in the bridging channel of the drain plate, crosses at least one of the other application media during the transition from the outlet plate into the discharge channel. This crossing reliably prevents the two application media from mixing.
Um eine Vermischung der Auftragsmedien auf dem Ablaufblech sicher auszuschließen, ist es vorteilhaft, wenn die Rinnen durch ein Blech voneinander getrennt sind.In order to reliably prevent mixing of the application media on the drain plate, it is advantageous if the channels are separated from one another by a plate.
Das Ablaufblech kann ein Gefälle aufweisen, um die Auftragsmedien möglichst schnell abführen zu können. Ein zufriedenstellender Abführstrom wird mit einem Gefälle von mindestens fünf Grad erreicht.The drain plate can have a slope so that the application media can be discharged as quickly as possible. A satisfactory discharge flow is achieved with a Gradient of at least five degrees reached.
Die Auftragsmedien können bevorzugt zu der Seite, an der Antriebe platziert sind, abgeführt werden. Dann kann von der anderen Seite, an der sich ein Führerstand befindet, die Vorrichtung vom Bedienpersonal des Führerstandes frei überschaut werden. Grundsätzlich können jedoch die Auftragsmedien zu beiden Seiten der Vorrichtung abgeführt werden.The application media can preferably be discharged to the side on which drives are placed. Then, from the other side, on which a driver's cab is located, the device can be freely surveyed by the operating personnel of the driver's cab. In principle, however, the application media can be removed on both sides of the device.
Die Auffangeinrichtung und die Ablaufeiπrichtung können einstückig ausgebildet sein. Dadurch wird die gesamte Einheit aus Auffangeinrichtung und Ablaufeinrichtung sehr formstabil, sodass ein zuverlässiger Ablauf der Auftragsmedien gegeben ist.The collecting device and the drain device can be formed in one piece. As a result, the entire unit comprising the collecting device and the drain device becomes very dimensionally stable, so that the application media run reliably.
In einer anderen Ausführuπgsform ist es jedoch auch möglich, dass die Auffangeinrichtung und die Ablaufeinrichtung separate Bauteile sind. Dann muss nur die Auffangeinrichtung bewegt werden, um den Beschichtungsvorgang zu beginnen oder zu beenden. Die Ablaufeinrichtung und mit ihr verbundene Abführschläuche können dann also stehen bleiben, sodass insgesamt eine kleinere Masse zu bewegen ist. In diesem Fall ist für die Auffangeinrichtung nur ein kleinerer Antrieb erforderlich. Außerdem kann die Auffangeinrichtung schneller unter den Vorhang verfahren werden oder unter dem Vorhang weggefahren werden, wenn die zu bewegende Masse kleiner ist.In another embodiment, however, it is also possible for the collecting device and the drain device to be separate components. Then only the catcher needs to be moved to start or end the coating process. The drain device and the discharge hoses connected to it can then remain standing, so that a smaller mass can be moved overall. In this case, only a smaller drive is required for the collecting device. In addition, the collecting device can be moved faster under the curtain or moved away under the curtain if the mass to be moved is smaller.
Die Auffangeinrichtung kann zwei Abschnitte aufweisen, die in Längsrichtung der Materialbahn in entgegengesetzte Richtungen verfahren werden können. Dann ist eine minimale Vermischung der Auftragsmedien absolut ausgeschlossen, wenn der Beschichtungsvorgang begonnen oder beendet wird. Eine minimale Vermischung der Auftragsmedien tritt jedoch auf, wenn die Abschnitte zum Beginn oder zum Ende des Beschichtungsvorganges in derselben Richtung verfahren werden.The collecting device can have two sections which can be moved in opposite directions in the longitudinal direction of the material web. Then a minimal mixing of the application media is absolutely impossible when the coating process is started or ended. Minimal mixing of the application media occurs, however, if the sections are moved in the same direction at the beginning or at the end of the coating process.
In einer besonderen Ausführungsform kann das zwischen den Abschnitten angeordnete Trennelement eine Umlenkeinrichtung zur Umlenkung der Auftragsmedien in die vorgesehenen Abschnitte aufweisen. Dann ist zu Beginn oder zum Ende des Beschichtungsvorganges eine minimale Vermischung der Auftragsmedien sicher ausgeschlossen, weil die Umlenkeinrichtung während des Verfahrens der Auffangeinrichtung das jeweilige Auftragsmedium in den dafür vorgesehenen Abschnitt umlenkt. Vorteilhafterweise ist die Umlenkeinrichtung verschwenkbar, so dass sie abhängig von der Bewegungsrichtung und dem zurückgelegten Verfahrweg entsprechend verschwenkt werden kann, um das Auftragsmedium optimal in den dafür vorgesehenen Abschnitt zu leiten.In a special embodiment, the separating element arranged between the sections can be a deflection device for deflecting the Have application media in the intended sections. Then minimal mixing of the application media is reliably excluded at the beginning or at the end of the coating process, because the deflection device deflects the respective application medium into the section provided for this purpose during the movement of the collecting device. The deflection device is advantageously pivotable, so that it can be pivoted depending on the direction of movement and the distance traveled, in order to optimally guide the application medium into the section provided for this purpose.
Wenn unter der Materialbahn eine untere Auftangeinrichtung vorgesehen ist, können die Auftragsmedien auch bei einem Abriss der Materialbahn aufgefangen werden. Da die verfahrbare Auffangeinrichtung bei einem Abriss der Materialbahn nicht schnell genug unter den Vorhang verfahren werden kann, ist die untere Auffangeinrichtung besonders vorteilhaft.If a lower collecting device is provided under the material web, the application media can also be collected if the material web is torn off. Since the movable collecting device cannot move under the curtain quickly enough when the material web is torn off, the lower collecting device is particularly advantageous.
In einer Weiterbildung der Erfindung können mit der unteren Auffangeinrichtung die Auftragsmedien ebenfalls separat aufgefangen werden.In a further development of the invention, the application media can also be collected separately with the lower collecting device.
In einer bevorzugten Ausführungsform weist die untere Auffangeinrichtung für jedes Auftragsmedium eine separate Rinne auf, um die Auftragsmedien separat auffangen zu können.In a preferred embodiment, the lower collecting device has a separate channel for each application medium in order to be able to collect the application media separately.
Um eine unerwünschte Vermischung der Auftragsmedien sicher auszuschließen, können die Rinnen beispielsweise durch Trennelemente voneinander getrennt sein.In order to reliably prevent undesired mixing of the application media, the channels can be separated from one another, for example, by separating elements.
Nachfolgend werden Ausführungsbeispiele einer erfindungsgemäßen Vorrichtung anhand der beiliegenden Zeichnung näher erläutert.Exemplary embodiments of a device according to the invention are explained in more detail below with reference to the accompanying drawing.
Im Einzelnen zeigen:Show in detail:

Fig. 2 is a perspective view of a curtain applicator with a drain device.
Fig. 1 zeigt eine Vorrichtung 10 zum Auftragen zweier einen Vorhang 11 und 12 bildenden Auftragsmedien. Die Auftragsmedien werden mittels eines sich quer über eine zu beschichtende Materialbahn 102 erstreckenden Vorhangauftragswerks 13 auf die Materialbahn 102 - hier in direkter Weise - aufgebracht. Unter den Vorhängen 11 und 12 ist eine zwei Abschnitte 14 und 15 aufweisende ebenfalls, wie das Auftragswerk 13 sich in Querrichtung Q erstreckende Auffangeinrichtung 16 angeordnet. Die Auffaπgeinrichtung 16 fängt die die Vorhänge 11 und 12 bildenden Auftragsmedien mit den Abschnitten 14 und 15 separat auf. Da die Auffangeinrichtung 16 jedes Auftragsmedium separat auffängt, können sich die Auftragsmedien nicht vermischen. Die aufgefangenen Auftragsmedien gelangen von der Auffangeinrichtung 16 zu einer sich in Längsrichtung der Materialbahn 102 erstreckenden Ablaufeinrichtung 17. Die Ablaufeinrichtung 17 führt die aufgefangenen Auftragsmedien ab, damit diese wieder für den weiteren Beschichtungsvorgang verwendet werden können. Die Ablaufeinrichtung 17 weist ein Ablaufblech 18 auf, an dessen Ende für jedes Auftragsmedium separate Abführrinnen 19 und 100 angeordnet sind. Um die Auftragsmedien möglichst schnell abführen zu können, weist das Ablaufblech 18 ein Gefälle auf.1 shows a device 10 for applying two application media forming a curtain 11 and 12. The application media are applied to the material web 102 - here in a direct manner - by means of a curtain applicator 13 extending across a material web 102 to be coated. Arranged under the curtains 11 and 12 is a catchment device 16, which also has two sections 14 and 15, like the application unit 13 extending in the transverse direction Q. The catcher 16 catches the application media forming the curtains 11 and 12 with the sections 14 and 15 separately. Since the collecting device 16 collects each application medium separately, the application media cannot mix. The collected application media pass from the collecting device 16 to a discharge device 17 extending in the longitudinal direction of the material web 102. The discharge device 17 removes the collected application media so that they can be used again for the further coating process. The drain device 17 has a drain plate 18, at the end of which separate discharge channels 19 and 100 are arranged for each application medium. In order to be able to discharge the application media as quickly as possible, the drain plate 18 has a slope.
Zu Beginn oder zum Ende eines Beschichtungsvorganges kann die über der Materialbahn 102 angeordnete Auffangeinrichtung 16 in Längsrichtung der Materialbahn 102 verfahren werden. In einer weiteren Ausführungsform ist es auch möglich, dass die Auffangeinrichtung 16 und die Ablaufeinrichtung 17 einstückig ausgebildet sind. Dann können die Auffangeinrichtung 16 und die Ablaufeinrichtung 17 gemeinsamen verfahren werden. In einer anderen Ausführungsform kann das Vorhangauftragswerk 13 entlang der Materialbahn 102 verfahren werden, so dass die Auffangeinrichtung 16 und die Ablaufeinrichtung 17 zu Beginn oder zum Ende des Beschichtungsvorganges nicht bewegt werden müssen. Unterhalb der Materialbahn 102 ist eine untere Auffangeinrichtung 101 angeordnet. Die untere Auffangeinrichtung 101 fängt die Auftragsmedien nach einem Abriss der Materialbahn 102 auf. Mit der unteren Auffangeinrichtung 101 können bevorzugt ebenfalls mehrere Auftragsmedien separat aufgefangen werden. Zu diesem Zweck kann die untere Auffangeinrichtung 101 für jedes Auftragsmedium mit einer separaten Rinne ausgestattet sein.At the beginning or at the end of a coating process, the collecting device 16 arranged above the material web 102 can be moved in the longitudinal direction of the material web 102. In a further embodiment, it is also possible for the collecting device 16 and the drain device 17 to be formed in one piece. Then the collecting device 16 and the drain device 17 can be moved together. In another embodiment, the curtain applicator 13 can be moved along the material web 102, so that the collecting device 16 and the drain device 17 do not have to be moved at the beginning or at the end of the coating process. A lower collecting device 101 is arranged below the material web 102. The lower collecting device 101 collects the application media after the web 102 has been torn off. The lower collecting device 101 can preferably also collect several application media separately. For this purpose, the lower collecting device 101 can be equipped with a separate channel for each application medium.
Fig. 2 zeigt eine bestimmte Ausführungsform einer Auffangeinrichtung 20 und einer Ablaufeinrichtung 21. Ein punktiert dargestelltes Auftragsmedium 22 und ein gestrichelt dargestelltes Auftragsmedium 23 fallen von einem Vorhangauftragswerk 204 in die zwei in Laufrichtung der Materialbahn hintereinander angeordneten Abschnitte 24 und 25 aufweisende Auffangeinrichtung 20. Die Abschnitte 24 und 25 weisen ein Trennelement 28 auf, um eine Vermischung der Auftragsmedien 22 und 23 zu verhindern. Außerdem sind die Abschnitte 24 und 25 mit Ablauföffnungen 26 versehen. Durch die Ablauföffnungen 26 können die Auftragsmedien 22 und 23 an die Ablaufeinrichtung 21 weitergegeben werden. Die Abschnitte 24 und 25 sind mit Schrägen 27 ausgestattet. Die Schrägen 27 leiten die Auftragsmedien 22 und 23 an die Ablauföffnungen 26 weiter. Außerdem kann das Auftragsmedium 22, das in den Abschnitt 24 fällt unter den Schrägen 27 des benachbarten Abschnitts 25 hindurch zur Ablaufeinrichtung 21 fließen. Die Schrägen 27 erfüllen somit eine weitere Funktion, indem sie es ermöglichen, dass sich die Auftragsmedien 22 und 23 kreuzen können, ohne dass sich die kreuzenden Auftragsmedien 22 und 23 miteinander vermischen. Anstelle der Schrägen kann natürlich auch Bogenform vorhanden sein.2 shows a specific embodiment of a collecting device 20 and a discharge device 21. A dotted application medium 22 and a dotted application medium 23 fall from a curtain applicator 204 into the two sections 24 and 25 arranged one behind the other in the running direction of the material web. The sections 24 and 25 have a separating element 28 in order to prevent mixing of the application media 22 and 23. In addition, the sections 24 and 25 are provided with drain openings 26. The application media 22 and 23 can be passed on to the discharge device 21 through the discharge openings 26. Sections 24 and 25 are provided with bevels 27. The bevels 27 pass the application media 22 and 23 on to the outlet openings 26. In addition, the application medium 22, which falls into the section 24, can flow under the bevels 27 of the adjacent section 25 to the drain device 21. The bevels 27 thus fulfill a further function in that they make it possible for the application media 22 and 23 to cross without the intersecting application media 22 and 23 mixing with one another. Instead of the bevels, there can of course also be an arc shape.
Die Ablaufeinrichtung 21 weist ein Ablaufblech 201 auf. Das Ablaufblech 201 ist mit Rinnen 29, in denen das Auftragsmedium 22 abläuft, und mit Rinnen 200, in denen das Auftragsmedium 23 abläuft, versehen. Somit kann jedes der Auftragsmedien 22 und 23 separat abgeführt werden. Am Ende des Ablaufbleches 201 sind Abführrinnen 202 und 203 vorgesehen, in denen die Auftragsmedien 22 und 23 separat abgeführt werden. Die Rinnen 200, die in Laufrichtung L der Materialbahn 102 verlaufen, überbrücken die sich in Querrichtung Q erstreckende Abführrinne 202. Somit kreuzt das Auftragsmedium 23 beim Übergang vom Ablaufblech 201 in die Abführrinne 203 das Auftragsmedium 22. Durch diese Kreuzung ist eine Vermischung der beiden Auftragsmedien sicher ausgeschlossen.The drain device 21 has a drain plate 201. The drain plate 201 is provided with grooves 29, in which the application medium 22 runs, and with grooves 200, in which the application medium 23 runs. Each of the order media 22 and 23 can thus be discharged separately. At the end of the drain plate 201, discharge channels 202 and 203 are provided, in which the application media 22 and 23 are discharged separately. The channels 200, which run in the running direction L of the material web 102, bridge the discharge channel 202 which extends in the transverse direction Q. Thus, the application medium 23 crosses the application medium 22 at the transition from the drain plate 201 to the discharge channel 203. This crossing means that the two application media are mixed certainly excluded.
Die Abführrinnen 202 und 203 führen die Auftragsmedien 22 und 23 quer zur Längsrichtung der Materialbahn 102 ab. An die Abführrinnen 202 und 203 können (hier nur in Figur 3 angedeutete) Abführschläuche 205 angeschlossen werden, durch die die Auftragsmedien 22 und 23 einem Vorratsbehälter zugeführt werden.The discharge channels 202 and 203 discharge the application media 22 and 23 transversely to the longitudinal direction of the material web 102. To the discharge channels 202 and 203 (here only indicated in FIG. 3) discharge hoses 205 can be connected, through which the application media 22 and 23 are fed to a storage container.
Figur 3 zeigt darüber hinaus eine Vorrichtung 10 bei der die Abführrinnen 19, 100, 202, 203 in Querrichtung der Vorrichtung 10 gesehen, nebeneinander angeordnet sind. Jede dieser Abführrinnen 19, 100, 202, 203 nimmt getrennt voneinander, das vom jeweiligen Abschnitt 14, 15, 24, 25 der Auffangeinrichtung 16, 20 aufgefangene und an die Ablaufbleche 18 bzw. 201 weiter gegebene Auftragsmedium 22, 23 auf, von wo aus es nach außerhalb der Vorrichtung 10 abgegeben wird. FIG. 3 also shows a device 10 in which the discharge channels 19, 100, 202, 203, seen in the transverse direction of the device 10, are arranged side by side. Each of these discharge channels 19, 100, 202, 203 receives, separately from one another, the application medium 22, 23 which is caught by the respective section 14, 15, 24, 25 of the collecting device 16, 20 and passed on to the drain plates 18 and 201, from where it is delivered outside the device 10.
