Abstract
Description
3eschichtungssystem für flexible Bahnen3-layer system for flexible sheets
Beschreibung Es sind Beschichtungssysteme bekannt, bei denen der Massebehälter zu einer Antragswalze hin durch einen Schaber begrenzt wird. Der Schaber ist starr und bildet zur Antragswalze hin einen den Masseauftrag bestimmenden Spalt.Description Coating systems are known in which the mass container is limited to an application roller by a scraper. The scraper is rigid and forms a gap that determines the mass application towards the application roller.
Ebenso kann bei einem elastischen Messer in Verbindung mit einerGravur auf der Antragswalze der Masseauftrag dosiert werden.Likewise, in the case of an elastic knife in connection with an engraving the mass application can be dosed on the application roller.
Das starre Schabermesser ist nur für mittlere und dicke Masseaufträge geeignet und hat den Nachteil, daß eine Deformation des Schabermessers und jede Unrundheit der Antragswalze zu unterschiedlichen Masseaufträgen führt.The rigid scraper knife is only for medium and thick bulk jobs suitable and has the disadvantage that a deformation of the doctor blade and each Out-of-roundness of the application roller leads to different mass orders.
Beim elastischen Messer in Verbindung mit einer Gravur bestimmtdie Gravur den Masseauftrag. Veränderungen des Masseauftrages erfordern den Tausch der Walze; sie können nicht stufenlos erfolgen.With the elastic knife in connection with an engraving Engraving the mass order. Changes to the bulk order require the exchange of the Roller; they cannot be made continuously.
Das erfindungsgemäße System bietet bei dünnen und mittleren Masseaufträgen eine Reihe von Vorteilen. Die glatte Walze mit einem Nutenschaber ist preisgünstiger; erleichtert die Reinigung, insbesondere bei Massen mit eingebautem Härter (Zweikomponentensystem), und erlaubt eine stufenlose Veränderung des Masseauftrages durch tangentiales Verschieben des mit Nuten versehenen Messers Die Zeichnung erläutert den Erfindungsgegenstand. Die Antrapalze(1) wird von der Masse (4) benetzt die im Behälter (2) bevorratet wird. Zwischen dem Behälter (2) und der Antragswalze (1)befindet sich ein elastischer Schaber (3), welcher entlang und parallel zur Walzenachse mit einer Vielzahl kleiner Nuten (5) verzahnt ist. Die Masse (4) gelangt in die Nuten (5), die am Walzenumfang einen freien Strömungsquerschnitt ergeben, dessen Größe durch Vertikalverschiebung des Messers veränderlich wird.The system according to the invention offers thin and medium bulk orders a number of advantages. The smooth roller with a groove scraper is cheaper; facilitates cleaning, especially for compounds with a built-in hardener (two-component system), and allows a stepless change of the mass application by tangential shifting of the grooved knife The drawing explains the subject of the invention. The Antrapalze (1) is wetted by the mass (4) which is stored in the container (2) will. An elastic one is located between the container (2) and the application roller (1) Scraper (3), which runs along and parallel to the roller axis with a large number of smaller Grooves (5) is toothed. The mass (4) gets into the grooves (5) on the roller circumference result in a free flow cross-section, its size by vertical displacement of the knife becomes changeable.
Durch Schräganordnung der Nuten (5) wird ein Verstreichen der Masse auf der Walzenoberfläche von (1)erzielt. Eine zur Walzenachse parallel angeordnete Nute im unteren Bereich des Nutenfeldes führt zum gleichen Effekt.Due to the inclined arrangement of the grooves (5), the mass is spread achieved on the roll surface of (1). One arranged parallel to the roller axis Grooves in the lower area of the groove field lead to the same effect.
Die Übertragung des Masseauftrages von der Walze (1) an die Materialbahn (6) erfolgt mit der Gegendruckwalze (7) oder durch Zwischenschalten sogenannter Übertragungswalze (n) (10) oder durch zwei von der Materialbahn umschlungene Leitwalzen (8) und (9), welche selbstdie Antragswalze (1) nicht berühren.The transfer of the mass application from the roller (1) to the material web (6) takes place with the counter-pressure roller (7) or by interposing what is known as Transfer roller (s) (10) or by two guide rollers wrapped around by the material web (8) and (9), which do not even touch the application roller (1).
Die Ausrüstung der Walze (1) oder (10) mit einer Release-Beschichtung aus Teflon, Silicon oder dergleichen verhindert bei dünner Beschichtung mittelviskoser Massen den Einschluß von Lufe-blasen.Bei einer Release-Beschichtung erfolgt die Abgabe des Masseauftrages von der Walzen an den Film vollkommen, so daß keine Spaltung des Masseauftrages auftritt, also eine saubere Walzenoberfläche an die Masseaufgabestelle zurückläuft. Dieser Effekt dient dem blasenfreien Auftrag; er kann durch Kühlungdes Releasebezuges verstärkt werden.Equipping the roller (1) or (10) with a release coating made of Teflon, silicone or the like prevents a thin coating of medium viscosity Masses the inclusion of run-bubbles. With a release coating, the Transfer of the mass application from the rollers to the film completely, so that no splitting of the mass application occurs, i.e. a clean roller surface at the mass application point runs back. This effect is used for bubble-free application; he can by cooling the Release reference to be strengthened.
