Für die Behandlung von Häuten und Papieren mit Silikon gibt es "Viele"bekannte Verfahren und Vorrichtungen. Man kennt die sogenannte Stabbeschichtung, bei der die Beschichtungswalze als teilweise im Becken mit Beschichtungsmittel gesunken umläuft und das zu beschichtende Bandmaterial zwischen der Beschichtungswalze und einer oberhalb derselben angebrachten .'Gegenwalze aus Gummi geleitet wird, indem das Beschichtung«- mi-ttel aus der Beschichtungswalze auf die Unterfläche des Bandmaterials übergeht. Damit das Beschichtungsmittel als eine geeignet dünne Schicht mit der Beschichtungswalze steigen sollte, muss dessen Viskosität verhältnismässig niedrig sein, aus welchem Grunde dessen Trockensubstanzgehalt höchstens 3 bis 8 % sein kann. Man kann auch eine gerasterte Beschichtungswalze verwenden. Der Überschuss vom Beschichtungsmittel kann aus der Beschichtungswalze entfernt werden, indem ein Schaber bzw. eine Rakel benutzt wird, der/die gegen die Walze angebracht ist.There are "many" known methods and devices for treating skins and papers with silicone. The so-called bar coating is known, in which the coating roller revolves as partially sunk in the basin with coating agent and the strip material to be coated is guided between the coating roller and a rubber counter roller attached above it, in that the coating is carried out by means of the coating roller passes to the lower surface of the band material. So that the coating agent should rise as a suitably thin layer with the coating roller, its viscosity must be relatively low, for which reason its dry matter content can be at most 3 to 8 % . A screened coating roller can also be used. The excess coating agent can be removed from the coating roll using a doctor blade attached against the roll.
Man-kennt auch die sogenannte Beschichtung mittels Gegenwalze, wobei das überschüssige Beschichtungsmittel aus der Beschichtungswalze mittels einer daneben angebrachten, in derselben Richtung umlaufenden Gegenwalze abgewischt wird. Bei sogenannten 4-Walzen- und 3-Walzenbeschichtungsverfahren können mehrere Walzen nebeneinander und/oder aufeinander verlegt werden.One also knows the so-called coating by means of a counter roller, the excess coating agent from the coating roller by means of an adjacent one in the same Direction of the rotating counter roller is wiped off. With so-called 4-roll and 3-roll coating processes several rollers can be laid next to each other and / or on top of each other.
Bei der Luftbürstenbeschichtung wird das überschüssige Beschichtungsmittel aus der Bandfläche durch Blasen mit der Luft entfernt.In the case of air brush coating, the excess coating agent is removed from the surface of the belt by blowing with the Air removed.
Bei allen oben beschriebenen Verfahren läuft das Bandmaterial oberhalb der Anstreichwalze in Berührung mit der Walze und mit Übergang des Beschichtungsmittels auf die untere Fläche des Bandmaterials. Die Übertragung des Stoffes erfolgt mittels der Anstreichwalze von unten nach oben, wobei der Stoff leicht flüssig sein muss.In all of the methods described above, the strip material runs above the paint roller in contact with the roller and with transfer of the coating agent to the lower surface of the strip material. The material is transferred by means of the paint roller from bottom to top, whereby the fabric must be slightly runny.

Damit die Schicht des Beschichtungsmaterials ausreichend dünn1 gemacht werden könnte, müssen sehr grosse Lösemittelmengen verwendet werden, sogar 95 bis 97 % von der Menge der Anstrichpasta. Während des Fertigungsprozesses muss das Lösemittel verdunstet werden. Weil besonders im Zusammenhang mit Silikonbehandlung als Lösemittel giftige aromatische Kohlenwasserstoffe, wie Toluen, Methylketon3 Benzen, Hexan usw., verwendet werden, verursachen die reichlichen Mengen von Lösemitteldämpfen Risiken sowohl bezüglich des Feuerschutzes als auch bezüglich der Arbeitshygiene. Ausserdem verursachen grosse Mengen von Lösemitteln einen grossen Bedarf an Trockenenergie, weil die Trockenluft auch nicht beinahe explosive Mengen von Lösemitteln enthalten darf,...- Die heisse Trockenluft wird nach aussen ventiliert und muss im Fabrikssaal durch aufgewärmte Luft ersetzt werden.In order that the layer of the coating material could be made sufficiently thin 1 , very large amounts of solvent must be used, even 95 to 97 % of the amount of the paint paste. The solvent must be evaporated during the manufacturing process. Because toxic aromatic hydrocarbons, such as toluene, methyl ketone 3 benzene, hexane etc., are used as solvents, especially in connection with silicone treatment, the copious amounts of solvent vapors cause risks both in terms of fire protection and industrial hygiene. In addition, large quantities of solvents cause a great need for dry energy, because the dry air must not contain almost explosive quantities of solvents ...- The hot dry air is ventilated to the outside and must be replaced by warmed up air in the factory.
Im neuesten, sogenannten Trockensilikonbehandlungsverfahren ist es möglieh gewesen, die Mengen von Lösemitteln wesentlich zu reduzieren. Ein Nachteil dieses Verfahrens ist aber der von verschiedenen Katalysatoren erzeugte Wasserstoff, der bei Störungen in der Ventilation Explosionsgefahr herbeiführt.In the latest so-called dry silicone treatment process, it has been possible to reduce the amounts of solvents substantially to reduce. A disadvantage of this process, however, is the hydrogen generated by various catalysts, the causes a risk of explosion in the event of malfunctions in the ventilation.
Das Verfahren gemäss der vorliegenden Erfindung ist dadurch gekennzeichnet, dass das Bandmaterial gegen die Anstreichwalze ausserhalb der von der Anstreichwalze und. vom Schaber gestalteten Rinne zugeführt wird, wobei das Beschichtungsmittel in einer an und für sich bekannten Weise aus der Anstreichwalze auf die gegen die Anstreichwalze laufende Fläche des Bandmaterials übergeht. The method according to the present invention is thereby characterized in that the strip material against the paint roller outside of the from the paint roller and. designed by the scraper Channel is fed, the coating agent in a manner known per se from the paint roller merges onto the surface of the strip material running against the paint roller.
Die Vorrichtung gemäss der Erfindung ist dadurch gekennzeichnet, dass sie Geräte für die Leitung des Bandmaterials gegen die Anstreichwalze ausserhalb der von der Anstreichwalze und vom. Schaber gestalteten Rinne aufweist.The device according to the invention is characterized in that it includes devices for guiding the strip material against the paint roller outside of the paint roller and from. Has scraper shaped groove.
Das Verfahren kann für die Beschichtung und Behandlung von verschiedenen Kunststoff- und Papierhäuten angewendet werden. Die Vorrichtung eignet sich besonders für die Silikonbehandlung von Papier und Haut, aber damit können auch andere ähnliche flüssige, auf Lösemittel gegründete Beschichtungsmittel, wieThe process can be used for the coating and treatment of various plastic and paper skins. The device is particularly suitable for the silicone treatment of paper and skin, but other similar ones can also be used with it liquid solvent based coating agents such as
030062/0800030062/0800
z.B. PVC, Heissfuge- und Beschichtungslackierstoffe usw., änge'strichen werden. Beim Verfahren gemäss der Erfindung kann die Lösemittelmenge der anzustreichenden Pasta wesentlich, sogar bis 50 %, reduziert werden. Ausserdem verlangt das Verfahren kein Methylketon oder Toluen als Lösemittel, sondern als Lösemittel ist z.B. das weniger giftige Hexan ausreichend.Eg PVC, hot joint and coating varnishes, etc., are painted. In the method according to the invention, the amount of solvent in the pasta to be coated can be reduced significantly, even up to 50%. In addition, the process does not require methyl ketone or toluene as solvents, but rather the less toxic hexane, for example, is sufficient.
Die niedrigen Lösemittelmengen reduzieren die Menge der Trockenenergie, reduzieren den Preis der Beschichtung, und die Vorrichtung braucht nicht notwendigerweise eine Gewinnungs- und Verbrennungsapparatur für die Lösemitteldämpfe.The low amounts of solvent reduce the amount of dry energy, lower the price of the coating, and the device does not necessarily need a recovery and combustion apparatus for the solvent vapors.
Trotz dem grossen Trockensubstanzgehalt der Beschichtung werden mit der Vorrichtung sehr niedrige Beschichtungsmittelmengen pro zu beschichtenden Quadratmeter von Haut erreicht. Bei Probefahrten mit der Vorrichtung sind Beschichtungsmittel-Despite the high dry substance content of the coating, the device produces very low amounts of coating agent per square meter of skin to be coated. During test drives with the device, coating agents

mengen von sogar 0,2 g/m erreicht worden.2
Quantities of as much as 0.2 g / m have been achieved.
Weil die Vorrichtung gemäss der Erfindung von einfacher Konstruktion ist, sind ihre Einkaufspreis und Betriebskosten günstiger als die von anderen Verfahren.Because the device according to the invention is of simple construction, its purchase price and operating cost are cheaper than other methods.
Die Erfindung wird nachstehend mit Bezug auf die beiliegende Zeichnung näher Beschrieben, welche Zeichnung die Vorrichtung gemäss der Erfindung schematisch als Seitenansich darstellt.The invention is described in more detail below with reference to the accompanying drawing, which drawing shows the device according to the invention is shown schematically as a side view.
Die Vorrichtung weist eine umlaufende hartverchromte Anstreichwalze H auf, deren oberfläche sonderbehandelt ist, z.B. mit Sandblas, Rasterung oder Punkenbearbeitung, und deren Geschwindigkeit im Verhältniz zum Bandmaterial 10 stufenlos geregelt werden kann. Die Walze hat eine verhältniseingestellte Triebvorrichtung, d.h. ihre Geschwindigkeit im Verhältnis zur Geschwindigkeit der Bahn bleibt im vorgestellten Verhältnis.The device has a revolving hard chrome-plated painting roller H , the surface of which is specially treated, for example with sandblasting, rasterization or dot processing, and the speed of which can be continuously regulated in relation to the strip material 10. The roller has a ratio-adjusted drive device, ie its speed in relation to the speed of the web remains in the ratio presented.
Gegen die Walze h ist ein oszillierender Schaber 2 angebracht, der derartig in eine schräge Stellung verlegt ist, dass dessen von der Walze weg gerichtete Kante höher gelegen ist als die gegen die Walze gelegene Kante. Somit bleibt zwischen der1 Walze und dem Schaber eine Rinne, die den.Becken 11 für die Anstreichpasta gestaltet. Der Schaber besteht aus einem Rahmen 1, Blatt 2 und Blattbefestigung 3. Die BelastungAn oscillating scraper 2 is attached against the roller h , which is moved in an inclined position in such a way that its edge directed away from the roller is situated higher than the edge located against the roller. This leaves a groove between the 1 roller and the scraper, which creates the basin 11 for the paint pasta. The scraper consists of a frame 1, sheet 2 and sheet attachment 3. The load
030062/0800030062/0800
des Schaberblattes gegen die Anstreichwalze kann mittels einer auf den Hebelarm 5 gerichteten Belastung F stufenlos eingestellt werden.of the scraper blade against the coating roller can be continuously adjusted by means of a load F directed onto the lever arm 5 can be set.
Oberhalb des Beckens 11 für die Pasta gibt es einen Zufuhrbehälter 7 für die Pasta, aus dem die Pasta in die Rinne zwischen der Walze 4 und dem Schaber 2 auf die obere Fläche des Schabers 2 zugeführt wird. Mittels- der Umlaufapparaturder Anstrichpasta wird die Pasta durch Pumpen oder in anderer Weise auf das Blatt 2 zugeführt. Von hier strömt der Überschuss von der Pasta als Überfluss aus beiden Enden des Schabergeräts zurück zum Pumpbecken (nicht in der Zeichnung dargestellt).Above the basin 11 for the pasta there is a feed container 7 for the pasta from which the pasta enters the channel between the roller 4 and the scraper 2 on the upper surface of the scraper 2 is fed. By means of the circulation apparatus Paint paste, the pasta is fed onto the sheet 2 by pumping or in some other way. The excess flows from here of the pasta as excess from both ends of the scraper back to the pump basin (not shown in the drawing).
Die Vorrichtung weist ausserdem zwei stufenlos einstellbare Steuerwalzen 8 und 9 auf, mit deren Hilfe der Berührungswinkel und die Berührungszeit der zu beschichtenden Bahn 10 gegen die Anstreichwalze eingestellt wird. In der Zeichnung ist mit gebrochenen Linien eine andere Stellung der Walzen 8 und sowie der Materialbahn 10 dargestellt, in welcher der Berührungswinkel kleiner ist.The device also has two continuously adjustable control rollers 8 and 9, with the help of which the contact angle and the contact time of the web 10 to be coated against the coating roller is adjusted. In the drawing is with broken lines another position of the rollers 8 and and the material web 10 shown in which the Contact angle is smaller.
Wenn die Vorrichtung im Betrieb ist, läuft die Anstreichwalze 1J in der in der Zeichnung mit dem Pfeil A angegebenen Richtung so, dass die Oberfläche der Walze beim Berührungspunkt der Walze und des Schabers 2 sich nach unten bewegt und Beschichtungsmittel aus der Rinne 11 durch die Spalte zwischen der Walze h und dem Schaber 2 nach unterhalb des Schabern 2 'trägt. Das zu beschichtende Bandmaterial 10 wird unter die Anstreichwalze 1J in der vom Pfeil B angegebenen Richtung geleitet, und das Beschichtungsmittel wird aufs Bandmaterial übertragen, wenn das Material gegen die Walze reibt. Die Bewegungsrichtung des Bandmaterials am Berührungspunkt mit der Walze ist mit der Oberfläche der Walze parallel und die Geschwindigkeit des Materials ist vorzugsweise etwas grosser als die Geschwindigkeit der Oberfläche der Walze. Bei der Übertragung des Beschichtungsmittels auf die Dosierwalze 4 wird die Schwerkraft benutzt, und eine Gleichmässigkeit der Belegeschicht wird erreicht, indem das Bandmaterial reibend unter die Anstreichwalze läuft. Die Steuerung des BandmaterialsWhen the device is in operation, the coating roller 1 J runs in the direction indicated by the arrow A in the drawing so that the surface of the roller at the contact point of the roller and the scraper 2 moves downwards and coating agent from the channel 11 through the Gaps between the roller h and the scraper 2 to below the scraper 2 'carries. The strip to be coated material 10 J is passed in the direction indicated by the arrow B direction under the Anstreichwalze 1, and the coating agent is transferred onto the tape material when the material rubs against the roll. The direction of movement of the strip material at the point of contact with the roller is parallel to the surface of the roller and the speed of the material is preferably somewhat greater than the speed of the surface of the roller. When the coating agent is transferred to the metering roller 4, the force of gravity is used, and the evenness of the covering layer is achieved by the strip material running under the coating roller with friction. The control of the strip material
030062/0800030062/0800
erfolgt mittels der Steuerwalzen 8 und 9, ohne Einsatz einer gegen die Änstreichwalze liegenden Gegenwalze.takes place by means of the control rollers 8 and 9, without the use of a the counter-roller lying against the coating roller.
Die Bahngeschwindigkeiten sowohl der Anstreichwalze 4 als auch der Materialbahn 10 können eingestellt werden. Durch Veränderung des Verhältnisses der Geschwindigkeiten kann die Menge der .Silikonschicht pro Flächenarealeinheit eingestellt werden. Die Menge der Beschichtung kann ausserdem dadurch eingestellt werden, dass die Berührungsfläche der zu beschichtenden Haut gegen die Anstreichwalze mittels der Steuerwalzen 8 und 9 verändert wird oder dass der Blattdruck des Schabers verändert wird. Auch die Natur der Oberflächenbearbeitung der Anstreichwalze beeinflusst die Dicke der Belegungsschicht.The web speeds of both the coating roller 4 and the material web 10 can be adjusted. By The amount of silicone layer per unit area can be adjusted by changing the ratio of the speeds will. The amount of coating can also be adjusted by adjusting the contact surface of the The skin to be coated is changed against the paint roller by means of the control rollers 8 and 9 or that the sheet pressure of the scraper is changed. The nature of the surface treatment of the paint roller also affects the thickness of the Occupancy layer.

ZUSAMMANFASSUNGSUMMARY
Ein Verfahren für die Beschichtung eines Bandmaterial auf der einen Seite mit einer auf Lösemittel gegründeten Schicht. Ein Schaber wird gegen eine umlaufende Anstreichwalze angebracht. Das Bandmaterial wird an der Anstreichwalze vorbei geleitet so, dass das Bandmaterial die Anstreichwalze berührt. Beschichtungsstoff wird nach oberhalb des Schabers, in die vom Mantel der Anstreichwalze und von Schaber gebildete Rinne zugeführt. Die Umlaufrichtung der Anstreichwalze is derartig, dass die Oberfläche der Anstreichwalze sich an der Berührungsstelle der Anstreichwalze· und des Schabers nach unten bewegt. Das Bandmaterial wird gegen die Anstreichwalze ausserhalb der von der Anstreichwalze und vom Schaber gestalteten Rinne zugeführt. Das Beschichtungsmittel geht aus der Anstreichwalze auf die gegen die Anstreichwalze laufende Fläche des Bandmaterials über.A method for coating a strip of material on the one side with a solvent based layer. A scraper is attached against a rotating paint roller. The tape material is guided past the paint roller so that the tape material contacts the paint roller. Coating material is fed above the scraper, into the channel formed by the coat of the paint roller and the scraper. The direction of rotation the paint roller is such that the surface of the paint roller is at the point of contact of the paint roller and the scraper moved down. The strip material is against the paint roller outside that of the paint roller and fed from the scraper-shaped groove. The coating agent goes from the paint roller to the against the paint roller running surface of the strip material over.
