Abstract

The coating device features a first applicator which, to begin with, forces coating substance applied on the shell of a web roll (1), in a press gap formed between said roll and a press roll (2), into the web (W), thereby impregnating it. This makes it possible to apply with maximum uniformity and without web breaks and wrinkles, immediately successively, a second coating layer during the still wet condition of the first layer where, naturally, again a web guide roll (3) is provided.

Description

Die Erfindung betrifft eine Auftragseinrichtung entsprechend dem Oberbegriff des Patentanspruchs 1 sowie entsprechendes Verfahren. Das Verfahren zur Beschichtung laufender Warenbahnen mit den zwei aufeinander folgenden Beschichtungsvorgängen, wobei die zuerst aufgetragene Schicht noch feucht ist, wenn die zweite Schicht aufgetragen wird, ist bekannt aus US 3,202,536. Die beiden Beschichtungsstationen sind hier sowohl an einer einzigen die Bahn führenden Walze angeordnet als auch an zwei aufeinander folgenden Walzen. Eine der letztgenannten entsprechende Einrichtung ist auch bekannt aus CA 882 640. Die letztgenannte unterscheidet sich von der anderen dadurch, daß in der ersten Beschichtungsstation der Auftrag mittels Auftragswalze erfolgt. Diese zuerst aufgetragene Schicht wird dann mittels Streichklinge vergleichmäßigt, wobei der Überschuß abgeschabt wird. Bei der anderen Einrichtung erfolgt in der ersten Beschichtungsstation ebenfalls ein Abschaben mittels einer Schaberklinge.The invention relates to an application device according to the preamble of claim 1 and corresponding method. The method for coating running material webs with the two successive coating processes, the layer applied first being still moist when the second layer is applied, is known from US Pat. No. 3,202,536. The two coating stations are arranged here on a single roller guiding the web as well as on two successive rollers. One of the latter corresponding devices is also known from CA 882 640. The latter differs from the other in that the application takes place in the first coating station by means of an application roller. This first applied layer is then evened out by means of a doctor blade, the excess being scraped off. In the other device, scraping by means of a doctor blade also takes place in the first coating station.

Die Aufgabe der Erfindung ist ein betriebssicheres Naß- in Naß-Streichverfahren mit bester Strichqualität und sparsamem Materialverbrauch zu schaffen.The object of the invention is to provide a reliable wet-on-wet coating method with the best coating quality and economical material consumption.

Gemäß der Erfindung wird eine neue Beschichtungseinrichtung gemäß dem Kennzeichen des Patentanspruchs 1 geschaffen. Hierbei ist als Vorteil zu nennen, daß die Beschichtung zunächst in geringem Maße auf die Warenbahn aufgetragen wird, wobei durch den Preßspalt zwischen der ersten Bahnführungswalze und der Preßwalze ein gleichmäßiges Einpressen der ersten Beschichtungsmenge erfolgt. Dadurch wird die Bahn quasi imprägniert, und es ist ohne weiteres möglich, gleichmäßig die Deckschicht mit der zweiten Beschichtungseinrichtung aufzutragen. Durch den Preßnip tritt keine große Beanspruchung, insbesondere Zug- oder Quetschbeanspruchung der Warenbahn auf. Die leicht in dem Stadium, wo es zu Bahnberührungen kommen kann, zum Verpressen der Bahn neigende oder sogar Bahnrisse herbeiführende Schaberklinge ist dort vermieden. Sehr vorteilhaft ist es, zwecks gleichmäßigem Auftrag einer dosierten Menge eine Rollrakel zu verwenden, deren Umfang mit Rillen versehen ist. Diese Rillen können sehr fein ausgebildet sein, so daß sich ein besonders gleichmäßiger Auftrag ergibt.According to the invention, a new coating device is created according to the characterizing part of patent claim 1. Here it is to be mentioned as an advantage that the coating is first applied to the web to a small extent, with the first nip of coating being uniformly pressed in by the press nip between the first web guide roller and the press roller. As a result, the web is quasi-impregnated, and it is easily possible to apply the cover layer evenly with the second coating device. Due to the press nip, there is no great stress, in particular tensile or crushing stress on the material web. The scraper blade, which tends to compress the web or even cause web breaks, is easily avoided at the stage where web contacts can occur. It is very advantageous to use a doctor blade, the circumference of which is provided with grooves, for the uniform application of a metered amount. These grooves can be very fine, so that there is a particularly uniform application.

Nachfolgend wird die Erfindung anhand dreier in den Figuren der Zeichnung dargestellter Beispiele erläutert.The invention is explained below using three examples shown in the figures of the drawing.

In Figur 1 ist die erste Bahnführungswalze, also die der ersten Beschichtungseinrichtung mit 1, die zugehörige Preßwalze mit 2 und die Bahnführungswalze der zweiten Beschichtungseinrichtung mit 3 bezeichnet. Die Bahnführung ist mit W angegeben. Die erste Beschichtungseinrichtung weist eine Auftragskammer 4 für die Beschichtungsmasse auf, in welche diese durch das Zuführrohr 5 eingeleitet wird. Die Auftragskammer ist als Düsenkammer mit einem Überlauf ausgebildet, so daß überschüssige Beschichtungsmasse in die Auffangwanne 7, die an der Auftragskammer 4 befestigt ist, überfließen kann. Die Auftragskammer 4 wird von einem Tragbalken 6 gehalten. Am in Drehrichtung der Bahnführungswalze 1 austrittsseiten Ende der Auftragskammer 4 befindet sich das Dosierelement, eine Rollrakel 8, die vorzugsweise eine mit Umfangsrillen versehene Oberfläche aufweist. Als zweite Beschichtungseinrichtung ist ebenfalls eine derartige Auftragskammer 13 mit Zuführrohr 14 vorgesehen. Es ist ebenfalls eine Auffangrinne 16 und ein Tragbalken 15 vorhanden. Anstelle der Rollrakel 8 ist hier aber eine Streichklinge 12 austrittsseitig in bezug auf die Auftragskammer 13 vorgesehen, die die zweite Auftragsschicht glättet. In dem zwischen der Bahnführungswalze 1 und der Preßwalze 2 gebildeten Preßspalt wird die in relativ genau dosierter Menge an Beschichtungsmasse in die Warenbahn, vorzugsweise eine Papier- oder Kartonbahn hineingepreßt und diese damit imprägniert. Ohne weitere Trocknung wird dann die Warenbahn W der zweiten Beschichtungseinrichtung zugeführt. Dabei kann sie über eine Breitstreckwalze 18 geleitet werden, um Faltenbildungen zu vermeiden.In Figure 1, the first web guide roller, that is, the first coating device with 1, the associated press roller with 2 and the web guide roller of the second coating device with 3. The path is indicated by W. The first coating device has an application chamber 4 for the coating material, into which it is introduced through the feed pipe 5. The application chamber is designed as a nozzle chamber with an overflow so that excess coating compound can overflow into the collecting trough 7, which is attached to the application chamber 4. The application chamber 4 is held by a support beam 6. At the end of the application chamber 4 on the exit side in the direction of rotation of the web guide roller 1 there is the metering element, a doctor blade 8, which preferably has a surface provided with circumferential grooves. Such an application chamber 13 with feed pipe 14 is also provided as the second coating device. There is also a gutter 16 and a support beam 15. Instead of the doctor blade 8, a doctor blade 12 is provided here on the outlet side with respect to the application chamber 13, which smoothes the second application layer. In the press nip formed between the web guide roller 1 and the press roller 2, the relatively precisely metered amount of coating compound is pressed into the web, preferably a paper or cardboard web, and impregnated therewith. The web W is then fed to the second coating device without further drying. It can be passed over an spreader roller 18 to avoid wrinkles.

Die Streichklinge 12 wird natürlich in jedem Fall in bekannter Weise durch die Anpreßmittel so angedrückt, daß sie gleichmäßig an der Bahnführungswalze 3 bzw. der Waranbahn anliegt und die Beschichtung sehr gleichmäßig glättet.The doctor blade 12 is of course pressed in a known manner by the pressing means so that it lies evenly on the web guide roller 3 or the monitor web and smoothes the coating very evenly.

Die Auftragswerke mit Auftragskammer sind bekannt z.B. aus US 4,250,211 und Auftragsrakel mit Sumpf und Rollrakel einschließlich Halter aus US 2,970,564. Eine Rollrakel, die mit die Umfangsrillen bildender Drahtumwicklung versehen ist, ist z.B. bekannt aus US 3,387,585.The orders with order chamber are known e.g. from US 4,250,211 and application squeegee with sump and roller squeegee including holder from US 2,970,564. A squeegee provided with wire wrapping forming the circumferential grooves is e.g. known from US 3,387,585.

Man kann durch eine zwischen den beiden Bahnführungswalzen 1 und 3 eingeschaltete Breitstreckwalze 18 den Bahnverlauf und die Bahnbeanspruchung durch Bahnzug noch wesentlich vergleichmäßigen.By means of an spreader roller 18 switched on between the two web guide rollers 1 and 3, the web course and the web stress due to web tension can be substantially evened out.

In Figur 1 ist gestrichelt eine Variante dargestellt, bei welcher die Bahnführungswalzen 1 und 3 unmittelbar nebeneinander angeordnet sind. In dem Spalt, der zwischen den beiden Walzen gebildet ist, verläuft die Bahn relativ reibungsfrei, jedenfalls ohne größere Anpreßkräfte.A variant is shown in broken lines in FIG. 1, in which the web guide rollers 1 and 3 are arranged directly next to one another. In the gap that is formed between the two rollers, the web runs relatively smoothly, at least without major contact forces.

Eine Anpressung im Nip zwischen Walze 1 und 3 ist nicht möglich, da Bahnlängung und Querdehnung zwischen dem Nip von Walze 1 und 3 und der Klinge 12 nicht ausgeglichen werden können.A pressure in the nip between roller 1 and 3 is not possible, since web elongation and transverse expansion between the nip of roller 1 and 3 and the blade 12 cannot be compensated for.

Das Grundprinzip der erfindungsgemäßen Auftragseinrichtung ist es, die erste Beschichtung nur in einem solchen Maße vorzunehmen, daß im wesentlichen nur eine Imprägnierung des Papiers erfolgt. Daher hängt die Menge der in der ersten Auftragseinrichtung aufgetragenen Streichmasse von der Saugfähigkeit des Papiers ab, welche u.a. im wesentlichen eine Funktion des Flächengewichts des Papiers ist. So werden z.B. für holzfreie Papiersorten Flächengewichte von mehr als 80 g/m2 verwendet. Bei diesen wegen ihrer größeren Porosität auch mit größerer Saugfähigkeit ausgestatteten Papieren beträgt das in der ersten Beschichtungseinrichtung aufgetragene Flächengewicht maximal etwa 7 g/m2, so daß insgesamt eine Schichtungsmenge von 15 g/m2 in beiden Beschichtungseinrichtungen aufgetragen wird. Die entsprechende Rillengröße beträgt dabei im Querschnitt maximal etwa 0,012 mm2. Dies gilt im wesentlichen für solche Rollrakel, die mit Drahtumwicklung versehen sind. Diese Rollrakel haben aber keine sehr große Standzeit.The basic principle of the application device according to the invention is only the first coating to such an extent that essentially only the paper is impregnated. Therefore, the amount of the coating slip applied in the first application device depends on the absorbency of the paper, which among other things is essentially a function of the basis weight of the paper. For example, basis weights of more than 80 g / m 2 are used for wood-free paper types. In the case of these papers, which are also equipped with greater absorbency because of their greater porosity, the basis weight applied in the first coating device is a maximum of about 7 g / m 2 , so that a total of 15 g / m 2 of coating is applied in both coating devices. The corresponding groove size is a maximum of about 0.012 mm 2 in cross section . This essentially applies to those doctor blades which are provided with wire wrapping. These squeegees do not have a very long service life.

Daher sind Rollrakelstäbe für die erfindungsgemäße Auftragseinrichtung entwickelt worden, die es ermöglichen, ein einwandfreien Strich über längere Betriebszeiträume herzustellen. Eine solche Rollrakel ist in Figur 2 skizziert, wobei zwischen den Rillen 20 sich Stege 21 befinden, die im Querschnitt parallel zur Mittelachse des Rollrakelstabes gesehen, eine zu dieser Mittelachse parallele Oberfläche aufweisen.Therefore, doctor blades have been developed for the application device according to the invention, which make it possible to produce a perfect line over longer operating periods. Such a doctor blade is sketched in FIG. 2, with webs 21 between the grooves 20 which, viewed in cross section parallel to the central axis of the doctor blade rod, have a surface parallel to this central axis.

Für den Querschnitt dieser Rillen kann etwa der Wert je Meter Arbeitsbreite des Rollrakelstabes von maximal 34 mm2 als obere Grenze angesehen werden.For the cross section of these grooves, the value per meter working width of the doctor blade rod of a maximum of 34 mm 2 can be regarded as the upper limit.

Bei Papieren minderwertigerer Qualität, also mit einem Flächengewicht von weniger als 80 g/m2 beträgt der Querschnitt der Rillen eines mit Drahtumwicklung versehenen Rollrakelstabes maximal etwa 0,006 mm2, um eine Auftragsschicht von 3 g/m2 mittels der ersten Beschichtungseinrichtung aufzutragen. Der Gesamtauftrag beträgt dann etwa 10 g/m2. In the case of papers of inferior quality, that is to say with a weight per unit area of less than 80 g / m 2 , the cross section of the grooves of a roller doctor rod provided with wire wrapping is a maximum of approximately 0.006 mm 2 in order to apply an application layer of 3 g / m 2 by means of the first coating device. The total order is then about 10 g / m2.

Die Gesamtquerschnittsfläche für Rollrakel nach Figur 2 beträgt dann je Meter Arbeitsbreite maximal 24 mm2.The total cross-sectional area for the doctor blade according to FIG. 2 is then a maximum of 24 mm 2 per meter of working width.

Auf diese Weise wird mittels der ersten Beschichtungseinrichtung eine so dünne Schicht aufgetragen, daß mittels der Preßwalze 2 praktisch eine Imprägnierung dieser dünnen Auftragsschicht des Papiers erfolgt. Dann kann ohne weiteres mit der zweiten Beschichtungseinrichtung, die an der zweiten Walze 3 angeordnet ist, der vollständige, endgültige Schichtauftrag erfolgen. Es hat sich gezeigt, daß auf diese Weise eine sehr hohe Strichqualität erreichbar ist.In this way, a layer so thin is applied by means of the first coating device that the thin application layer of the paper is practically impregnated by means of the press roller 2. Then the complete, final layer application can easily be carried out with the second coating device, which is arranged on the second roller 3. It has been shown that a very high stroke quality can be achieved in this way.

Es hat sich somit gezeigt, daß die erfindungsgemäße Einrichtung sehr viel effektiver arbeitet, als die eingangs genannte gemäß US-PS 32 02 536. Der Gedanke bei jener Einrichtung war es, eine sehr hohe Konsistenz der ersten Beschichtung zu verwenden, damit die Eindringtiefe des Lösungsmittels nicht so groß ist. Der Nachteil bei jener Einrichtung war aber, daß die erste Besichichtung doch relativ dick aufgetragen wurde, wobei es schwierig ist, diese erste Schicht mit einer Streichklinge genügend zu glätten. Erfindungsgemäß erfolgt auch das Auftragen beider Beschichtungen mittels eines Auftragswerkes, das eine unter Druck stehende Auftragskammer aufweist. Auch diese scheint für ein sehr gutes Streichergebnis beizutragen. Die Anordnung gemäß der CA-PS 882 640 scheint noch schlechter im Ergebnis zu sein als die Anordung gemäß der genannten US-Patentschrift.It has thus been shown that the device according to the invention works much more effectively than the above-mentioned according to US-PS 32 02 536. The idea with that device was to use a very high consistency of the first coating, so that the penetration depth of the solvent is not that big. The disadvantage with this device was, however, that the first coating was applied relatively thickly, and it is difficult to smooth this first layer sufficiently with a doctor blade. According to the invention, both coatings are also applied by means of an application unit which has an application chamber which is under pressure. This also seems to contribute to a very good streak result. The arrangement according to CA-PS 882 640 appears to be even worse in result than the arrangement according to the mentioned US patent.

Bei der Anordnung gemäß Figur 3 ist eine andere Auftragseinrichtung der Bahnführungswalze 1 zugeordnet, an welcher ein zusammen mit dem Tragbalken 9 den Sumpf aus Beschichtungsmasse bildender Halter 11 für die Rollrakel 10 vorgesehen ist. Da es sich um einen offenen Sumpf handelt, ist hier die nötige Pumpenleistung geringer als im Fall von Figur 1.In the arrangement according to FIG. 3, another application device is assigned to the web guide roller 1, on which a holder 11 for the doctor blade 10 is provided together with the supporting beam 9 which forms the sump of coating material. Since it is an open sump, the pump output required is lower than in the case of FIG. 1.

The process is characterized in that the coating is applied from the first application unit to the shell of the first roll in a metered quantity and that the applied quantity is then pressed in the paper or board web through a press nip, which is formed by the first roll (1) and the press roll (2), in order to impregnate the web. Here the basis weight of this first layer amounts to a maximum of 7 g/m2, with the applied quantity being metered in such a way that it maximally corresponds to the absorption capacity of the paper.
2. Unit for the implementation of a process in which two immediately successive layers are laid on top of each other, while the first layer is still wet, with at least one rotating web guide roll each (1, 3) being planned for the first as well as the second coating process and one application unit assigned to each roll (4-8; 12-16). The unit is characterized in that the first application unit has a press nip which is formed by the first (1) and another roll (2), that an application station (4) is assigned to the first roll (1), preferably a nozzle applicator with a metering rod (8), which has peripheral grooves and is positioned as a metering unit at the discharge end of the nozzle applicator (4), and that the peripheral grooves have a maximum cross section of 0.012 mm2 per groove in an axial section through the metering rod (8), with the chamber of the application station which contains the coating being limited at the roll (1) by the metering rod (8) and its holder (11).
3. The unit according to claim 2 is characterized in that the peripheral grooves have a maximum cross section of 0.012 mm2 for paper grades with a basis weight of over 80 g/m2 and a maximum of 0.006 mm2 for paper grades with a basis weight of 80 g/m2 at the most.
4. Unit for the implementation of the process, characterized in that the first application unit has a press nip which is formed by the first (1) and another roll (2), that a nozzle applicator (4) is assigned to the first roll (1), with a metering rod (8) which has peripheral grooves and is positioned as a metering unit at the discharge end of the nozzle applicator (4), and that the peripheral grooves have a total maximum cross section per meter operating width of the metering rod of 34 mm2 in an axial section through the rod (8).
5. Unit according to one of the claims 1 to 4, characterized in that the metering rod has peripheral grooves, and that the surface of the webs between them is parallel to the center axis, seen from the direction of the center axis of the metering rod, with the width of these surfaces, seen from this direction of the center axis, amounting to the maximum width of the cross section of the peripheral grooves (20) at the most.
