Description

Die Erfindung betrifft eine Vorrichtung zum Auftragen von Substanzen auf bahnförmiges Material. Derartige Auftrags- und Beschichtungsmaschinen sind bekannt und umfassen eine über die Breite des bahnförmigen Materials sich erstreckende Auftragswalze, welche die in einer Auftragswanne enthaltene Substanz auf dem bahnförmigen Material aufträgt, wobei das Material zwischen der Auftragswalze und einer Gegenanlagewalze hindurchgeführt wird. Dabei ist es ferner bekannt, dass die Auftragswalze mittels eines langgestreckten Magnetbalkens magnetisch gegen die Gegenanlagewalze gepresst wird. Eine derartige Vorrichtung ist z. B. in der EP 0901 839 A1 offenbart. Aus US 4 538 541 ist eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1 bekannt.The invention relates to a device for applying substances to sheet material. Such application and coating machines are known and comprise an applicator roll extending across the width of the sheet material, which deposits the substance contained in a applicator trough on the sheet material, the material being passed between the applicator roll and a counter-tenter roll. It is also known that the applicator roll is magnetically pressed by means of an elongated magnetic bar against the counter-roller. Such a device is z. B. in the EP 0901 839 A1 disclosed. Out US 4,538,541 a device according to the preamble of claim 1 is known.

Als Nachteil dieses direkten Auftragsverfahrens wird gesehen, dass die Auftragswalze einer Änderung der zu verarbeitenden Bahnbreite des Materials angepasst werden muss. Dazu muss die Maschine stillgesetzt und die Auftragswalze ausgetauscht werden.A disadvantage of this direct application method is that the applicator roll must be adapted to a change in the web width of the material to be processed. To do this, the machine must be shut down and the applicator roll replaced.

Bei einem Wechsel der Auftragssubstanz oder einer Reinigung der Auftragswanne muss die Maschine ebenfalls stillgesetzt und die Auftragswanne ausgebaut werden. Zuvor muss jedoch die Materialbahn entfernt werden. Dies ist ein erheblicher Nachteil.When changing the application substance or cleaning the application tray, the machine must also be shut down and the application tray removed. Before that, however, the material web must be removed. This is a significant disadvantage.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zum Auftragen von Substanzen auf bahnförmiges Material derart weiterzubilden, dass, mit nur geringem Aufwand und ohne entfernen der Materialbahn ein Wechsel der Auftragssubstanz bzw. ein Austausch und eine Reinigung der Auftragswanne möglich ist, sowie des weiteren eine bessere Kühlung des im Inneren der Hauptwalze angeordneten Magnetsystems zu ermöglichen.The object of the invention is to develop a device for applying substances to web-like material such that, with little effort and without removing the web, a change of the application substance or an exchange and a cleaning of the applicator tub is possible, as well as the other to allow better cooling of the magnet system arranged inside the main roller.

Diese Aufgaben werden durch die Merkmale des unabhängigen Patentanspruchs gelöst.These objects are achieved by the features of the independent claim.

Die Vorrichtung umfasst ein Maschinengerüst, eine langgestreckte, rohrförmig ausgebildete, rotierend angeriebene Hauptwalze, mindestens eine Auftragsrolle, eine innerhalb der Hauptwalze sich erstreckende, magnetische Anpresseinrichtung zum Anpressen der Auftragsrolle an die Hauptwalze, eine Zuführeinrichtung zum Benetzen der Auftragsrolle mit der aufzutragenden Substanz und mindestens eine weitere Rolle/ Walze, die in einem Abstand zur Auftragsrolle am Umfang der Hauptwalze angeordnet ist, wobei das bahnförmige Material zwischen der Rolle/Walze und der Hauptwalze hindurchgeführt und durch die Rolle/Walze in Kontakt mit der Hauptwalze bringbar ist.The apparatus comprises a machine frame, an elongate, tubular, rotationally grooved main roll, at least one application roller, a magnetic pressing device extending inside the main roll for pressing the application roll against the main roll, a feeding device for wetting the application roll with the substance to be applied and at least one another roller / roller, which is arranged at a distance from the application roller on the circumference of the main roller, wherein the web-like material between the roller / roller and the main roller and passed through the roller / roller in contact with the main roller can be brought.

Die Vorrichtung sieht also eine indirekte Beschichtung der Rollenware, d. h. des bahnförmigen Materials, vor. Den wesentlichen Vorteil stellt dabei neben der indirekten Art der Beschichtung und der kostengünstigen Bauart insbesondere die erreichbare Unabhängigkeit von der Bahnbreite der zu beschichtenden Materialbahn dar. Da die Hauptwalze durch die Auftragsrolle permanent neu mit der Auftragssubstanz beschichtet wird, kann kein Eintrocken bzw. Antrocknen der Auftragssubstanz an der Hauptrolle stattfinden. Es entfallen auch bei fliegendem Wechsel des zu beschichtenden Materials mit unterschiedlichen Breiten das üblicherweise notwendige rasche Umstellen des Magnetanpresssystems bzw. die Anpassung der Breite der Auftragsrolle an die Breite der Materialbahn.The device thus sees an indirect coating of the roll goods, d. H. of the sheet material, before. The main advantage is in addition to the indirect nature of the coating and the cost-effective design in particular the achievable independence of the web width of the web to be coated. Since the main roll is permanently re-coated by the job role with the contract substance, no drying or drying of the application substance take place in the main role. It also accounts for flying change of the material to be coated with different widths, the usually necessary rapid adjustment of Magnetanpresssystems or the adaptation of the width of the application roller to the width of the web.

Ein weiterer Vorteil der indirekten Beschichtung ist die dadurch mögliche höhere Durchlaufgeschwindigkeit der Materialbahn.Another advantage of the indirect coating is the resulting higher throughput speed of the material web.

Gemäß einer ersten Ausgestaltung der Erfindung ist vorgesehen, die Oberflächengeschwindigkeit der Hauptwalze mit der darauf befindlichen Auftragssubstanz unterschiedlich zur Oberflächengeschwindigkeit des bahnförmigen Materials zu wählen, insbesondere die Oberflächengeschwindigkeit der Hauptwalze um bis zu 40% geringer zu halten verglichen mit der Oberflächengeschwindigkeit des bahnförmigen Materials. Die Einstellbarkeit dieses Geschwindigkeitsunterschiedes soll von Null bis zu 100% im Vor- als auch Nachlauf möglich sein.
Als typische Werte können beispielsweise 100 m/min Oberflächengeschwindigkeit der Hauptwalze und 150 bis 200 m/min Geschwindigkeit des bahnförmigen Materials genannt, wobei die Geschwindigkeiten von Stillstand bis Sollgeschwindigkeit beliebig regelbar sein müssen.
Diese Maßnahme führt zu einer entsprechend geringeren und/oder gleichmäßigeren Schichtdicke der Auftragssubstanz auf der Materialbahn.According to a first embodiment of the invention, it is provided to select the surface speed of the main roller with the application substance thereon different from the surface speed of the web material, in particular to keep the surface speed of the main roller by up to 40% less compared to the surface speed of the web material. The adjustability of this speed difference should be possible from zero to 100% in the pre- and after-run.
As typical values, for example, 100 m / min surface speed of the main roller and 150 to 200 m / min speed of the web material called, the speeds from standstill to target speed must be adjustable.
This measure leads to a correspondingly lower and / or more uniform layer thickness of the application substance on the material web.

In einer bevorzugten Ausbildung der Erfindung kann die Auftragsrolle antreibbar ausgerüstet werden, so dass die Relativgeschwindigkeit der Auftragsrollenoberfläche zur Hauptwalzenoberfläche regelbar ist und dadurch die Dicke der Auftragsschicht beeinflusst bzw. auf die Konsistenz (dynamische Viskosität und Tixotropie) eingegangen werden kann.In a preferred embodiment of the invention, the application roller can be drivably equipped, so that the relative speed of the application roller surface can be regulated to the main roller surface and thereby influenced the thickness of the coating layer or on the consistency (dynamic viscosity and tixotropy) can be received.

Dabei kann die Auftragsrolle auch durch zwei oder mehrere übereinander oder nebeneinander angeordneten Auftragsrollen ersetzt werden, wodurch eine indirekte Beaufschlagung der Hauptwalze mit der Auftragssubstanz und damit der Schwall (Keil) der Auftragssubstanz im Bereich des sich verengenden Einlaufzwickels reduziert bzw. ganz vermieden werden kann. Dabei werden beide übereinander oder nebeneinander angeordneten Auftragsrollen durch das Magnetsystem an die Hauptwalze gepresst. Die vorzugsweise zwei Auftragsrollen können hierbei in radialer Richtung zur Hauptwalze im wesentlichen hintereinander- oder nebeneinanderliegend angeordnet sein. Für den Fall, daß die beiden Auftragsrollen radial zur Hauptwalze nebeneinander auf einem Umkreis liegen, können die Auftragsrollen voneinander beabstandet sein, wohingegen die Abstandsrollen keinen gegenseitigen Abstand aufweisen, wenn sie radial zur Hauptwalze hintereinander angeordnet sind.In this case, the application roller can also be replaced by two or more superposed or juxtaposed application roles, whereby an indirect application of the main roller with the application substance and thus the torrent (wedge) of the contract substance in the narrowing inlet gusset can be reduced or avoided altogether. Both superimposed or juxtaposed application roles are pressed by the magnet system to the main roller. The preferably two application rollers may in this case be arranged in the radial direction to the main roller essentially one behind the other or side by side. In the event that the two application rollers are adjacent to each other radially to the main roller on a circumference, the application rollers can be spaced apart, whereas the spacer rollers have no mutual distance when radially to the main roller in a row are arranged.

In einer ersten Variante ist vorgesehen, dass die Rolle/Walze als Anlegewalze ausgebildet ist, die zusammen mit einer weiteren Anlegewalze das bahnförmige Material in Kontakt mit der Hauptwalze bringt. Das Auftragsmedium wird also von der magnetisch angepressten Auftragsrolle auf die Hauptwalze übertragen und von dort durch die Relativgeschwindigkeit von Hauptwalze zum bahnförmigen Material über eine Kontaktstrecke, die abhängig ist von der Position der Anlegewalzen, auf das Material übertragen. Der Vorteil ist die kostengünstige Herstellung der Auftragsrolle. Weiterhin erfolgt die Übertragung der aufzutragenden Substanz durch das Magnetsystem in Verbindung mit der Auftragsrolle auf die Hauptwalze sehr gleichmäßig.In a first variant, it is provided that the roller / roller is designed as a contact roller, which brings the sheet-like material in contact with the main roller together with a further application roller. The application medium is thus transferred from the magnetically pressed application roller to the main roller and transferred from there by the relative speed of the main roller to the web-shaped material over a contact path which is dependent on the position of the application rollers on the material. The advantage is the cost-effective production of the job role. Furthermore, the transfer of the substance to be applied by the magnet system in conjunction with the application roller to the main roller is very uniform.

In einer anderen Ausführungsform ist vorgesehen, daß die Rolle/Walze als Anpressrolle ausgebildet ist, die mittels einer magnetischen Anpresseinrichtung gegen die Hauptwalze pressbar ist. Vorteil hierbei ist, dass die Aufbringung der Substanz auf das bahnförmige Material hier quasi zwangsweise erfolgt, wobei durch das Magnetsystem eine Einstellung des Anpressdruckes der Anpressrolle sehr gut definierbar ist und der Anpressdruck insbesondere nicht von der Spannung des bahnförmigen Materials über die Breite generell abhängig ist.In another embodiment it is provided that the roller / roller is designed as a pressure roller which can be pressed by means of a magnetic pressing device against the main roller. The advantage here is that the application of the substance to the sheet-like material here is virtually forced, wherein by the magnet system, an adjustment of the contact pressure of the pressure roller is very well defined and the contact pressure in particular is not generally dependent on the tension of the web material across the width.

Erfindungsgemäß ist die Zuführeinrichtung für die aufzutragende Substanz als Auftragswanne ausgebildet, die zusammen mit der Auftragsrolle in Längsrichtung gegenüber der Hauptwalze verschiebbar und schubladenartig aus der Vorrichtung ausziehbar ist. Dieses seitliche Ausziehen der Auftragswanne, gegenüber dem bekannten Ausbau nach vorne aus der Vorrichtung, hat den Vorteil, dass für einen Wechsel der Auftragssubstanz bzw. im Falle von Reinigungsarbeiten an der Auftragswanne das bahnförmige Material nicht mehr entfernt werden muss. Durch die seitlich offene und zugängliche Konstruktion kann deshalb auch eine Entleerung der Wannen in eingebautem Zustand erfolgen. Vorteilhaft ist die Auftragswanne im eingefahrenen Zustand kippbar ausgeführt, so daß eine einfache und rasche Entleerung der aufzutragenden Substanz möglich ist. Gemäss dem Stand der Technik mussten volle bzw. mit Auftragssubstanzen gefüllte Wannen mühsam und sorgfältig zum Entleeren transportiert werden.According to the invention, the feeding device for the substance to be applied is designed as a dispensing trough, which is displaceable out of the device together with the application roller in the longitudinal direction relative to the main roller and drawer-like. This lateral extraction of the applicator tub, compared to the known expansion forward of the device, has the advantage that the web-like material does not have to be removed for a change of the application substance or in the case of cleaning work on the applicator tub. Due to the laterally open and accessible construction, it is therefore also possible to empty the troughs when installed. Advantageously, the applicator trough is tilted executed in the retracted state, so that a simple and rapid emptying of the substance to be applied is possible. According to the prior art, full or filled with contract substances tubs had to be laboriously and carefully transported to empty.

Generell gesagt ist bei der erfindungsgemäßen Vorrichtung ein seitlich offener Zugriff auf die Stirnseite der Rollen/Walzen bzw. der Auftragswanne möglich.Generally speaking, in the device according to the invention a laterally open access to the end face of the rollers / rollers or the applicator tub is possible.

Erfindungsgemäß ist die Hauptwalze mittels Außenringlagern offen am Maschinengerüst gelagert. Diese Außenlagerung bietet gegenüber dem Stand der Technik den Vorteil der besseren Kühlung des im Inneren der Hauptwalze angeordneten Magnetsystems, da eine freie Luftzirkulation innerhalb der Hauptwalze möglich ist. Eine übermäßige Erwärmung des Magnetsystems reduziert dessen Leistung, was durch die offene Bauweise der Hauptwalze nun verringert oder vermieden werden kann. Der bevorzugte Durchmesser der Hauptwalze beträgt 400 mm.According to the invention, the main roll is mounted by means of outer ring bearings open on the machine frame. This external storage offers over the prior art the advantage of better cooling of the arranged inside the main roll magnet system, since a free air circulation within the main roll is possible. Excessive heating of the magnet system reduces its performance, which can now be reduced or avoided by the open design of the main roll. The preferred diameter of the main roll is 400 mm.

In einer bevorzugten Ausbildung der Erfindung sind Randabstreifrakeln vorgesehen, die seitlich an der Auftragsrolle verschiebbar angeordnet sind und in definierten Bereichen an der Auftragsrolle anliegen. Mittels der beiden seitlich angeordneten Randabstreifrakeln wird die aufzutragende Substanz seitlich an den Rändern von der Auftragsrolle abgestreift derart, daß die Hauptwalze nur in einem gewünschten und einfach einstellbaren Bereich mit der Auftragssubstanz beschichtet wird und folglich die Materialbahn nur auf dem gewünschten Bereich mit der Auftragssubstanz versehen wird. Es ergeben sich so einstellbare, nicht beschichtete Randbereiche auf der Materialbahn.In a preferred embodiment of the invention Randabstreifrakeln are provided, which are arranged laterally displaceable on the application roller and rest in defined areas on the job role. By means of the two laterally arranged Randabstreifrakeln the substance to be applied is stripped laterally at the edges of the application role such that the main roller is coated only in a desired and easily adjustable range with the application substance and consequently the web is provided only on the desired area with the application substance , This results in adjustable, non-coated edge regions on the material web.

Figur 1 zeigt eine erste Ausführungsform der erfindungsgemäßen Auftragsmaschine. Kernstück ist die Hauptwalze 6, die offen am Maschinengerüst 16 (Fig. 3) gelagert ist. Dies gestattet den Zugriff auf die innen hohl ausgebildete Hauptwalze 6. In der Hauptwalze 6 ist, in Längsrichtung gesehen, ein Magnetsystem 7 angeordnet, welches aus einer Vielzahl von Magnetspulen besteht. Das Magnetsystem 7 wirkt auf eine, unterhalb der Hauptwalze 6 angeordnete, Auftragsrolle 8 und drückt bzw. zieht diese in Kontakt mit der Hauptwalze 6. Unterhalb der Auftragsrolle 8 befindet sich eine Auftragswanne 10, die mit einer Beschichtungssubstanz, z. B. Klebstoff, gefüllt ist, wobei die Auftragsrolle 8 teilweise in die Beschichtungssubstanz eintaucht. Mittels einer Zuführung 9 für die Auftragssubstanz kann die Auftragswanne entsprechend befüllt werden. Ein Überschuss von Auftragssubstanz wird durch eine Überlaufwanne bzw. Rücklaufwanne 12 aufgefangen und wieder in den Kreislauf zurückgeführt. Die Auftragswanne 10 kann in vertikaler Richtung durch eine Verstelleinrichtung 11 verstellt werden, wodurch die Eintauchtiefe der Auftragsrolle 8 in die Auftragssubstanz eingestellt werden kann. FIG. 1 shows a first embodiment of the coating machine according to the invention. The centerpiece is the main roll 6, which is open on the machine frame 16 (FIG. Fig. 3 ) is stored. This allows access to the inner hollow main roller 6. In the main roller 6, seen in the longitudinal direction, a magnet system 7 is arranged, which consists of a plurality of magnetic coils. The magnet system 7 acts on a, disposed below the main roller 6, application roller 8 and pushes or pulls them in contact with the main roller 6. Below the application roller 8 is a applicator trough 10, which is coated with a coating substance, for. B. adhesive, is filled, wherein the application roller 8 is partially immersed in the coating substance. By means of a feed 9 for the application substance, the application tray can be filled accordingly. An excess of application substance is passed through an overflow pan or return trough 12 collected and returned to the circulation. The application tub 10 can be adjusted in the vertical direction by an adjusting device 11, whereby the immersion depth of the application roller 8 can be set in the application substance.

Oberhalb der Hauptwalze sind vorzugsweise zwei Anlegewalzen 1, 3 angeordnet, über welche die zu beschichtende Materialbahn 4 geführt ist. Die Anlagewalze 3 ist linear bis zu einem Maximalanschlag 13 verstellbar, wodurch die Materialbahn 4 in Kontakt mit der Hauptwalze 6 bringbar ist.Above the main roll two application rollers 1, 3 are preferably arranged, over which the material web 4 to be coated is guided. The contact roller 3 is linearly adjustable up to a maximum stop 13, whereby the material web 4 can be brought into contact with the main roller 6.

Die Hauptwalze 6 ist in der angegebenen Pfeilrichtung rotierend angetrieben, wobei die Materialbahn 4 mit der entsprechenden Geschwindigkeit der Hauptwalze 6 an deren Oberfläche vorbeigeführt wird.The main roller 6 is driven in rotation in the indicated arrow direction, wherein the material web 4 is guided past the surface thereof at the corresponding speed of the main roller 6.

Die in der Auftragswanne 10 befindliche Auftragssubstanz wird von der Auftragsrolle 8 aufgenommen, die vom Magnetsystem 7 an die Hauptwalze 6 gedrückt wird. Dadurch wird die Auftragssubstanz 15 auf die Oberfläche der Hauptwalze 6 übertragen. Die Auftragswalze 8 läuft passiv mit der Hauptwalze 6 mit, kann aber auch einen eigenen Antrieb aufweisen, so daß diese mit einer definierten Relativgeschwindigkeit zur Hauptwalze 6 läuft. Die Auftragssubstanz 15 wird von der Hauptwalze 6 mitgenommen und auf die Materialbahn 4 übertragen, die ebenfalls mit einer Relativgeschwindigkeit zur Hauptwalze an dieser entlang läuft. Das Beschichten der Materialbahn geschieht innerhalb einer Kontaktstrecke 14, deren Länge im wesentlichen von der Position der Anlegewalze 3 abhängt.The application substance located in the application tub 10 is received by the application roller 8, which is pressed by the magnet system 7 to the main roller 6. As a result, the application substance 15 is transferred to the surface of the main roller 6. The applicator roll 8 passes passively with the main roll 6, but may also have its own drive, so that it runs at a defined relative speed to the main roll 6. The application substance 15 is taken away from the main roll 6 and transferred to the material web 4, which also runs along it at a relative speed to the main roll. The coating of the material web takes place within a contact section 14, the length of which depends essentially on the position of the application roller 3.

Eine zweite Ausführungsform der Erfindung ist in Figur 2 gezeigt. Im Vergleich mit Figur 1 sind hierbei gleiche Bauteile mit gleichen Bezugsziffern versehen. Die Funktionsweise der Hauptwalze 6, der Auftragsrolle 8 und der Auftragswanne 10 und deren zugehörigen Teile entspricht der in Zusammenhang mit Figur 1 beschriebenen Funktionsweise. Unterschiedlich ist die Art und Weise der Übertragung der Auftragssubstanz 15 von der Hauptwalze 6 auf die Materialbahn 4. Es sind wiederum die Anlegewalzen 1 und 3 vorgesehen, die hier jedoch hauptsächlich als Umlenkwalzen arbeiten. Zusätzlich ist zwischen den Anlagewalzen 1, 3 eine Anpressrolle 2 vorgesehen, welche über ein zweites Magnetsystem 5 mit definierbarer Kraft an die Hauptwalze 6 anpressbar ist. Das Magnetsystem 5 ist ebenfalls innerhalb der Hauptwalze 6 angeordnet und kann mit dem Magnetsystem 7 eine Einheit bilden. Durch die Anpressrolle 2 wird nun die Materialbahn 4 mit definierter Kraft an die Hauptwalze 6 gepresst, wodurch die Übertragung der auf der Hauptwalze 6 befindlichen Auftragssubstanz 15 auf die Materialbahn 4 definiert gesteuert werden kann. Je nach Anpressdruck der Anpresswalze 2 kann die Beschichtungsstärke auf der Materialbahn 4 gesteuert werden. Die Übertragung der Auftragssubstanz von der Hauptwalze 6 auf das Papier erfolgt also zwangsweise und ist insbesondere nicht abhängig von der Spannung der Materialbahn über deren Breite gesehen. Auch bei dieser Ausführungsform kann die Relativgeschwindigkeit zwischen Hauptwalze 6 und Materialbahn 4 regelbar sein, durch unterschiedliche Antriebsgeschwindigkeiten der Hauptrolle 6 und der Materialbahn 4.A second embodiment of the invention is in FIG. 2 shown. In comparison with FIG. 1 Here are the same components provided with the same reference numerals. The operation of the main roller 6, the application roller 8 and the applicator tub 10 and its associated parts corresponds to that in connection with FIG. 1 described operation. The manner of transferring the application substance 15 from the main roller 6 to the material web 4 is different. Again, the application rollers 1 and 3 are provided, which, however, mainly function as deflection rollers. In addition, a pressure roller 2 is provided between the contact rollers 1, 3, which can be pressed against the main roller 6 via a second magnet system 5 with a definable force. The magnet system 5 is also disposed within the main roll 6 and may be integral with the magnet system 7. By the pressure roller 2, the web 4 is now pressed with a defined force to the main roller 6, whereby the transmission of the main roller 6 located on the application substance 15 can be controlled defined on the web 4. Depending on the contact pressure of the pressure roller 2, the coating thickness on the material web 4 can be controlled. The transfer of the application substance from the main roll 6 to the paper thus takes place forcibly and in particular is not seen as a function of the tension of the material web over its width. Also in this embodiment, the relative speed between the main roller 6 and the material web 4 can be controlled by different driving speeds of the main roller 6 and the material web 4th

Beide in den Figuren 1 und 2 dargestellten Ausführungsformen zeichnen sich durch eine indirekte Übertragung der Auftragssubstanz auf die Materialbahn aus, da die Auftragssubstanz zunächst von der Auftragsrolle 8 auf die Hauptwalze 6 übertragen wird und in einem zweiten Schritt von der Hauptwalze 6 auf die Materialbahn.Both in the FIGS. 1 and 2 embodiments shown are characterized by an indirect transfer of the application substance to the material web, since the application substance is first transferred from the application roller 8 to the main roller 6 and in a second step from the main roller 6 to the web.

Der grundsätzliche Aufbau der Auftragsmaschine kann Figur 3 entnommen werden, wo ersichtlich ist, daß die Auftragsmaschine eine platzsparende Anordnung besitzt. Die Hauptwalze 6 ist an einem Maschinengerüst 16 offen gelagert. Aus Gründen der Übersichtlichkeit sind die Anlegewalzen 1, 3 sowie die Anpressrolle 2 nicht gezeigt. Diese werden je nach Ausführungsform oberhalb der Hauptwalze 6 angeordnet. Innerhalb der Hauptwalze sind die Magnetsysteme 7, 5 angeordnet.The basic structure of the order machine can FIG. 3 taken where it can be seen that the applicator has a space-saving arrangement. The main roller 6 is mounted on a machine frame 16 open. For reasons of clarity, the application rollers 1, 3 and the pressure roller 2 are not shown. These are arranged depending on the embodiment above the main roll 6. Within the main roll, the magnet systems 7, 5 are arranged.

Unterhalb der Hauptwalze 6 befindet sich die Auftragswanne 10, in welcher die Auftragsrolle 8 (nicht gezeigt) angeordnet ist. Mittels der Verstelleinrichtung 11 kann die Auftragswanne 10 in vertikaler Richtung 18 verstellt werden. Mittels-der Wannenverstellung 17 kann die Auftragswanne 10 zusammen mit der Auftragsrolle 8 seitlich in Pfeilrichtung 19 aus dem Maschinengestell 16 herausgezogen und eingeführt werden. Dieses seitliche Herausziehen der Auftragswanne 10 bzw. Auftragsrolle 8 hat ferner noch den Vorteil, daß eine Stufenanordnung von mehreren Maschinen möglich ist. Durch die Möglichkeit der seitlichen Wannenmanipulation kann eine treppenförmige Bauweise mehrerer Auftragsmaschinen erfolgen.Below the main roll 6 is the application tray 10, in which the application roller 8 (not shown) is arranged. By means of the adjusting device 11, the applicator pan 10 can be adjusted in the vertical direction 18. By means of the tub adjustment 17, the application tub 10 can be pulled out and introduced laterally in the direction of arrow 19 out of the machine frame 16 together with the application roller 8. This lateral extraction of the applicator tub 10 or job roll 8 also has the advantage that a step arrangement of several machines is possible. Due to the possibility of lateral tub manipulation, a staircase-shaped construction of several coating machines can take place.

Durch die Verstellmöglichkeiten von Auftragswanne 10 und Auftragsrolle 8 in vertikaler Richtung 18 und horizontaler Richtung 19 ergibt sich trotz kompakter Bauweise der Auftragsmaschine eine gute Zugänglichkeit für Wartungs- und Reparaturarbeiten.The adjustment of application tray 10 and application roller 8 in the vertical direction 18 and horizontal direction 19 results in spite of the compact design of the coater good accessibility for maintenance and repair work.

In den Figuren 4 und 5 ist die Möglichkeit dargestellt, an beiden Seiten der Auftragsrolle 8 eine Randabstreifrakel 20 anzuordnen, welche an der Auftragsrolle 8 anliegt und die auf die Hauptwalze aufzutragenden Substanz 15 seitlich an den Rändern der Auftragsrolle 8 abstreift. Die Bereiche 21 an den Rändern der Auftragsrolle 8 bleiben demnach frei von Auftragssubstanz 16, so daß dort auch keine Auftragssubstanz 15 auf die Hauptwalze 6 aufgebracht,wird.
Die Randabstreifrakeln 20 sind parallel zur Längserstreckung der Auftragsrolle 8 verschiebbar, wie es mit den Doppelpfeilen 23 in Figur 5 angedeutet ist. Dadurch ist die Breite des wirksamen Bereichs 21 der Randabstreifrakeln 20 auf der Auftragsrolle 8 einstellbar. Die Hauptwalze 6 wird nur in dem gewünschten und einfach einstellbaren Bereich 22 mit der Auftragssubstanz 15 benetzt, so daß die Materialbahn 4 ebenfalls nur im gewünschten, eingestellten Bereich 22 mit der Auftragssubstanz beschichtet wird.In the FIGS. 4 and 5 the possibility is shown, to arrange a Randabstreifrakel 20 on both sides of the application roller 8, which rests against the application roller 8 and strikes the substance to be applied to the main roller 15 laterally at the edges of the application roller 8. The areas 21 at the edges of the application roller 8 thus remain free of application substance 16, so that there is no application substance 15 applied to the main roller 6, is.
The Randabstreifrakeln 20 are parallel to the longitudinal extent of the application roller 8 displaced, as it with the double arrows 23 in FIG. 5 is indicated. Thereby, the width of the effective portion 21 of the Randabstreifrakeln 20 on the application roller 8 is adjustable. The main roller 6 is wetted only in the desired and easily adjustable range 22 with the application substance 15, so that the material web 4 also only in desired, adjusted range 22 is coated with the application substance.

Die Randabstreifrakeln 20 bestimmen also die Breite des mit der Auftragssubstanz 15 beschichteten Bereiches 22 der Materialbahn, wobei die Ränder der Materialbahn 4 z.B. in einem Bereich von 50 mm von der Auftragssubstanz 15 freigehalten werden können.The edge scraper blades 20 thus determine the width of the area 22 of the material web coated with the application substance 15, the edges of the material web 4 being e.g. can be kept free of the application substance 15 in a range of 50 mm.

Figur 6 zeigt, daß die Hauptwalze 6 mittels Außenringlagern 24 offen am Maschinengerüst 16 gelagert ist. Diese Außenlagerung bietet gegenüber dem Stand der Technik den Vorteil der besseren Kühlung des im Inneren der Hauptwalze 6 angeordneten Magnetsystems 7, da durch die offene Lagerung eine freie Luftzirkulation innerhalb der Hauptwalze 6 möglich ist. Die Hauptwalze 6 wird im gezeigten Beispiel von einem Antrieb 25 über einen Zahnriemen angetrieben. FIG. 6 shows that the main roller 6 is mounted by means of outer ring bearings 24 open on the machine frame 16. This external storage offers over the prior art the advantage of better cooling of the arranged inside the main roller 6 magnet system 7, as a free air circulation within the main roller 6 is possible by the open storage. The main roller 6 is driven in the example shown by a drive 25 via a toothed belt.
