Abstract

PCT No. PCT/AT87/00068 Sec. 371 Date Sep. 2, 1988 Sec. 102(e) Date Sep. 2, 1988 PCT Filed Nov. 18, 1987 PCT Pub. No. WO88/03845 PCT Pub. Date Jun. 2, 1988.Disclosed is an apparatus for use in coating and possibly impregnating fabric webs with a coating compound. The apparatus utilizes a magnetic element or cylinder, located on a first side of a fabric web, to attract a magnetically attractable squeegee device, located on a second side of the fabric web, into contact with the fabric web. A second squeegee device or a cylinder is mounted against the magnetic eleemtn and is also located on the first side of the fabric web. This second squeegee device is also located such that when the first squeegee device is attracted toward and contacts the fabric web, the fabric web comes into contact with the second squeegee device, thus providing that the fabric web will be contacted on both sides with equal pressure by the respective squeegee devices.

Description

Die Erfindung bezieht sich auf eine Einrichtung zur Beschichtung von Warenbahnen mit einem auf einer Seite der Warenbahn angeordneten Magnetbalken oder einer vorzugsweise ruhend angeordneten Magnetwalze, durch welche(n) eine auf der gegenüberliegenden Seite der Warenbahn angeordnete Streicheinrichtung gegen die Warenbahn gepreßt wird.The invention relates to a device for coating material webs with a magnetic bar arranged on one side of the material web or a magnet roller, preferably arranged at rest, by means of which a coating device arranged on the opposite side of the material web is pressed against the material web.

Bei Verwendung von Magnetbalken zur Erzeugung der Rakel anpreßkraft hat man gemäß AT-A-289 158 einen über die Reihe der Elektromagneten des Magnetbalkens durchgehenden Stützkörper vorgesehen, welcher eine der Rakel zugewandte Vertiefung aufweist, die durch ein Gleitblech abgedeckt ist. Die Anordnung entspricht in ihrer Wirkung weitgehend einer Luftrakel, in welcher nur die gespannte Druckdecke dem Rakeldruck entgegenwirkt.When using magnetic bars to generate the doctor pressure, one has provided according to AT-A-289 158 a support body which is continuous over the row of electromagnets of the magnetic bar and has a recess facing the doctor which is covered by a sliding plate. The effect of the arrangement largely corresponds to an air knife, in which only the tensioned printing blanket counteracts the doctor blade pressure.

Die Bemühungen, eine geeignete Unterstützung für den Rakelkörper zu finden, sind dahin gegangen, den die Rakel unterstützenden Bereich flach zu machen und die von der Rakel eingeleiteten Kräfte möglichst gleichmäßig auf eine möglichst große Fläche zu verteilen. Von dieser Voraussetzung ausgehend war es keineswegs selbstverständlich, daß es möglich sein würde, das Prinzip der magnetischen Anpressung auf das beidseitige Beschichten von Warenbahnen mittels Streicheinrichtungen anzuwenden. Vom Anmelder durchgeführte Versuche haben in überraschender Weise gezeigt, daß es erfindungsgemäß möglich ist, vorzusehen, daß auch an der zweiten Seite der Warenbahn, der genannten Streicheinrichtung gegenüberstehend und diese abstützend, eine zweite Streicheinrichtung vorhanden bzw. der Magnetbalken oder eine vorzugsweise ruhend angeordnete Magnetwalze als solche ausgebildet ist.Efforts to find suitable support for the doctor body have been made to make the area supporting the doctor flat and to distribute the forces introduced by the doctor as evenly as possible over as large an area as possible. Based on this assumption, it was by no means self-evident that it would be possible to apply the principle of magnetic pressure to the double-sided coating of material webs by means of coating devices. Experiments carried out by the applicant have surprisingly shown that it is possible according to the invention to provide that a second coating device is also present on the second side of the web, opposite and supporting the aforementioned coating device, or the magnetic bar or a magnet roller, preferably arranged at rest, as such is formed.

Bei aller Verschiedenheit der möglichen konstruktiven Durchführungen läuft die Erfindung immer darauf hinaus, daß ein von einem Magnetbalken (oder einer Magnetwalze) angezogener Druckkörper, der entweder selbst eine Streicheinrichtung bildet oder eine solche belastet, eine annähernd linienförmige Belastung der Warenbahn bewirkt, welche von der magnetbalkenseitigen Streicheinrichtung aufgenommen wird. Die Streicheinrichtung auf der Seite des Magnetbalkens kann dabei entweder in bekannter Weise ein flexibles Metallblatt oder Kunststoffblatt sein, welches sich am Magnetbalken abstützt, oder aber eine Auflage auf dem Magnetbalken, welche spitzwinkelig auf jene Stelle der Warenbahn zuläuft, an welcher die vom Magnetbalken angezogene Streicheinrichtung liegt.In spite of the diversity of the possible design implementations, the invention always boils down to the fact that a pressure body attracted by a magnetic bar (or a magnetic roller), which either forms a coating device itself or loads it, causes an approximately linear loading of the material web, which is caused by the magnetic bar side Coating device is included. The coating device on the side of the magnetic bar can either be a flexible metal sheet or plastic sheet in a known manner, which is supported on the magnetic bar, or a support on the magnetic bar, which runs at an acute angle to the point on the web at which the coating device attracted by the magnetic bar lies.

Einzelheiten der Erfindung werden anschließend anhand der Zeichnung näher erläutert. In dieser stellt

  • Fig. 1 ein erstes Ausführungsbeispiel dar, Fig. 2 bis 7 zeigen verschiedene Varianten für den erfindungswesentlichen Auftragungsbereich mit zwei zusammenwirkenden Streicheinrichtungen, Fig. 8 und 9 zeigen zwei weitere Ausführungsbeispiele,
  • Fig. 10 und 11 weitere Varianten der Gestaltung des Auftragungsbereiches.
  • Fig. 1 beschreibt die Erfindung im Zusammenhang mit einer vertikal nach oben laufenden Warenbahn 3, ohne jeodch auf eine solche räumliche Orientierung eingeschränkt zu sein. Die Warenbahn 3 verläuft beim dargestellten Ausführungsbeispiel über Walzen 6,6 durch einen Trog 7, welcher eine Auftragsmasse enthält, und bedeckt sich dabei beidseitig mit dieser Masse. Auftragsmenge und Auftragstiefe bzw. Beschichtungsdicke werden durch die zusammenwirkenden Streicheinrichtungen 2 und 4 bestimmt, zwischen denen die Warenbahn 3 in Richtung des Pfeiles 11 hindurchbewegt wird.
Details of the invention are subsequently explained in more detail with reference to the drawing. In this poses
  • 1 shows a first exemplary embodiment, FIGS. 2 to 7 show different variants for the application area essential to the invention with two co-operating coating devices, FIGS. 8 and 9 show two further exemplary embodiments,
  • 10 and 11 further variants of the design of the application area.
  • Fig. 1 describes the invention in connection with a vertically upward web 3, without being limited to such a spatial orientation. In the exemplary embodiment shown, the web 3 runs over rollers 6, 6 through a trough 7, which contains an application mass, and is covered on both sides with this mass. The application quantity and application depth or coating thickness are determined by the cooperating coating devices 2 and 4, between which the material web 3 is moved in the direction of arrow 11.

Zur Anpressung der in diesem Beispiel als Rakelklingen ausgebildeten Streichelemente 2,4 ist in bekannter Weise ein eine Reihe von Magneten umfassender Magnetbalken 1 vorgesehen, welcher sich normal zur Zeichenebene, also quer zur Warenbahn 3 erstreckt. Dieser Magnetbalken 1 übt eine Anziehungskraft auf Gegenstände aus magnetisierbarem Material aus und kann daher im einfachsten Fall zur unmittelbaren Anpressung der Streichelemente herangezogen werden, wenn diese, wie in Fig. 2, 4 und 5 dargestellt, als massiver Körper aus magnetisierbarem Material ausgebildet sind. Es ist jedoch auch durchaus möglich, die Streichrakelklingen 2 in insbesondere beim Schablonendruck üblicher Weise als flexibles Metallband auszubilden und, wie in Fig. 1 und 3 dargestellt, durch einen magnetisierbaren, vom Magnetbalken 1 mit variablem Druck angepreßten Druckkörper 5 zu belasten (vgl. Fig. 1 und 3). Erfolgt die Belastung der als Rakelklinge ausgebildeten Rakeleinrichtung 2 ganz nahe an ihrem freien ende, dann sind die in die Rakelhalterung 8 eingeleiteten Momente sehr gering und die Rakelhalterung 8 braucht die als Rakelklinge ausgebildete Streicheinrichtung 2 nur gegen Herausziehen, nicht aber gegen Verdrehen oder in Längsrichtung zu sichern. Anpreßdruck und Anstellwinkel, welche die Eindringtiefe bzw. die Auftragsmenge bestimmen und die Behandlung damit mehr als Beschichtung oder mehr als Imprägnierung gestalten, sind bei einer solchen Anordnung weitgehend voneinander unabhängig steuerbar.In order to press on the coating elements 2, 4, which are designed as doctor blades in this example, a magnetic bar 1 comprising a series of magnets is provided in a known manner and extends normally to the drawing plane, that is to say transversely to the web 3. This magnetic bar 1 exerts an attractive force on objects made of magnetizable material and can therefore be used in the simplest case for direct pressing of the coating elements if, as shown in FIGS. 2, 4 and 5, they are designed as a solid body made of magnetizable material. However, it is also entirely possible to design the doctor blade blades 2 as a flexible metal strip, in particular in the manner customary in stencil printing, and, as shown in FIGS. 1 and 3, to load them with a magnetizable pressure body 5 pressed by the magnetic bar 1 with variable pressure (see FIG 1 and 3). If the load on the squeegee device 2 designed as a squeegee blade is very close to its free end, then the moments introduced into the squeegee holder 8 are very low and the squeegee holder 8 needs the squeegee device 2 designed as a squeegee blade only to be pulled out, but not against twisting or in the longitudinal direction to back up. Contact pressure and angle of attack, which determine the depth of penetration or the amount applied and thus make the treatment more like a coating or more than an impregnation, can be controlled largely independently of one another in such an arrangement.

Bei der bisher im Schablonendruck eingesetzten magnetischen Anpressung von Streichrakeln wird der Druck der Rakeleinrichtung 2 auf die Warenbahn 3 von einem flachen Gegenkörper aufgenommen oder allenfalls von einer Walze großen Durchmessers. Im Rahmen der gegenständlichenIn the magnetic pressing of doctor blades previously used in stencil printing, the pressure of the doctor device 2 on the web 3 is absorbed by a flat counter body or at most by a roller of large diameter. As part of the objective

Erfindung ist hingegen vorgesehen, auch die Abstützung der Streicheinrichtung 2 auf der Seite des Magnetbalkens 1 als eine zweite Streicheinrichtung 4 auszubilden. Diese zweite Streicheinrichtung 4 kann, wie in Fig. 1 und 2 dargestellt, als elastisches Metallblatt ausgebildet sein, welches nahe seinem freien Ende in einer vom Magnetbalken 1 getragenen Abstützleiste 9 anliegt. Es ist aber auch möglich (vgl. Fig. 3 und 4), die zweite Streichrakel 4 als keilförmige Auflage auf den Magnetbalken 1 auszubilden. Wesentlich ist dabei, daß die Streicheinrichtungen 2 und 4 zusammen einen Keilspalt bilden, was ohre weiteres auch erzielt werden kann, wenn beide Streichrakeln, so wie in Fig. 5 dargestellt, im Auflagebereich abgerundet sind.In contrast, the invention provides for the support of the coating device 2 on the side of the magnetic bar 1 to be designed as a second coating device 4. This second coating device 4 can, as shown in FIGS. 1 and 2, be designed as an elastic metal sheet which lies near its free end in a support bar 9 carried by the magnetic bar 1. But it is also possible (see. Fig. 3 and 4), the second doctor blade 4 as a wedge-shaped support on the Form magnetic bar 1. It is essential that the coating devices 2 and 4 together form a wedge gap, which can also be achieved if both coating doctor blades, as shown in FIG. 5, are rounded in the support area.

Aus Fig. 6 und 7 ist ersichtlich, daß die rechten und linken Hälften von Fig. 2 bis 5 beliebig miteinander kombiniert werden können. So stellt Fig. 6 die linke Seite von Fig. 3 in Kombination mit der rechten Seite von Fig. 5 dar, Fig. 7 die linke Seite von Fig. 4 ebenfalls in Kombination mit der rechten Seite von Fig. 5.6 and 7 that the right and left halves of FIGS. 2 to 5 can be combined with one another as desired. 6 shows the left side of FIG. 3 in combination with the right side of FIG. 5, FIG. 7 shows the left side of FIG. 4 also in combination with the right side of FIG. 5.

Fig. 8 beschreibt eine Einrichtung mit abwärts laufender Warenbahn 3. Hier bilden die Streicheinrichtungen 2 und 4 gleichzeitig den vorratsbehälter für die auf die Warenbahn 3 aufzutragende Beschichtungsmasse.8 describes a device with a web 3 running downwards. Here, the coating devices 2 and 4 simultaneously form the storage container for the coating composition to be applied to the web 3.

Bei der Einrichtung nach Fig. 9 ist der wirksame Teil der Streicheinrichtung 2 als Rundstab ausgebildet. Durch Verdrehen des Führungsstabes 10 in Pfeilrichtung ist es möglich, bei teilweiser Abnützung des wirksamen Bereiches der Streicheinrichtung 2 einen noch nicht verwendeten Oberflächenbereich zum Einsatz zu bringen, welcher die gewünschte Linienberührung auf einer exakten Geraden sicherstellt. In ähnlicher Weise könnte eine gleichmäßige Abnützung der Oberfläche der durch einen Rundstab gebibldeten Streichrundung der Streicheinrichtung 2 durch im Vergleich zur Geschwindigkeit der Bahn 3 langsames Drehen dieses Streichrundstabes 2 erzielt werden.9, the effective part of the coating device 2 is designed as a round bar. By turning the guide rod 10 in the direction of the arrow, it is possible, with partial wear of the effective area of the coating device 2, to use a surface area which has not yet been used and which ensures the desired line contact on an exact straight line. In a similar manner, a uniform wear of the surface of the coating rounding of the coating device 2, which is formed by a round rod, could be achieved by rotating this coating round rod 2 slowly in comparison to the speed of the web 3.

Fig. 10 zeigt, daß auch Streicheinrichtungen 4 die Form eines ruhend angeordneten Ruridstabes haben können; es kann jedoch auch ein solches Streichelement als Streicheinrichtung wirken, deren Oberfläche sich relativ zur warenbahn 3 bewegt.10 shows that coating devices 4 can also have the form of a resting Rurid rod; However, such a coating element can also act as a coating device, the surface of which moves relative to the web 3.

In Fig. 11 ist dargestellt, daß der Krümmungsradius der Streicheinrichtung 4 (hier eines den Magneten 1 umgebenden zylindrischen Rohres) relativ groß sein kann, solange sichergestellt ist, daß im Winkelbereich zwischen Streicheinrichtung 4 und Warenbahn 3 die Auftragsmasse durch die gleitende Reibung zwischen diesen beiden Elementen nicht nur geglättet, sondern auch abgestreift wird.In Fig. 11 it is shown that the radius of curvature of the coating device 4 (here a cylindrical tube surrounding the magnet 1) can be relatively large, as long as it is ensured that in the angular range between the coating device 4 and the web 3 the application mass due to the sliding friction between these two Elements not only smoothed, but also stripped.

Die Anpressung der erfindungsgemäß vorgesehenen zweiten Streicheinrichtung 4 an die'Warenbahn 3 erfolgt in allen Ausführungsbeispielen dadurch, daß der Magnetbalken 1 eine Kraft auf die Streicheinrichtung 2 ausübt, welche von der zweiten Streicheinrichtung 4 aufgenommen wird. Diese Kräfte sind natürlich gleich groß, was jedoch nicht bedeutet, daß die Beschichtung der Vorder- und Rückseite der Warenbahn 3 identisch gewählt werden muß. Je nach der Wahl des durch die Form und Anordnung der Streicheinrichtungen bedingten Anstellwinkels verteilt sich die auf beiden Seiten gleich große Kraft auf verschieden große Flächen, sodaß eine unterschiedliche Druckverteilung erzeugt werden kann. Statt die Warenbahn 3 durch einen Trog laufen zu lassen, ist es auch möglich, sie in anderer Weise beidseits mit Auftragsmasse zu beladen, welche dann von den Streicheinrichtungen 2 und 4 überstrichen bzw. abgestrichen wird, um das gewünschte Ausmaß von Beschichtung, Imprägnierung und Glättung zu erzielen. Es ist aber selbstverständlich auch möglich, diese zum beidseitigen Beschichten geeignete erfindungsgemäße Einrichtung auch zum einseitigen Beschichten zu verwenden., The pressing of the inventively provided second coating device 4 is performed in all embodiments of the 'web 3 characterized in that the magnet beam 1 exerts a force on the coating device 2 which is received from the second coater. 4 These forces are of course the same size, but this does not mean that the coating of the front and back of the web 3 must be chosen identically. Depending on the choice of the angle of attack caused by the shape and arrangement of the coating devices, the force which is of equal magnitude on both sides is distributed over differently large areas, so that a different pressure distribution can be generated. Instead of letting the material web 3 run through a trough, it is also possible to load it on both sides with application mass, which is then coated or coated by the coating devices 2 and 4 in order to achieve the desired extent of coating, impregnation and smoothing to achieve. However, it is of course also possible to use this device according to the invention suitable for coating on both sides for coating on one side.
