Description
Gießvorrichtung Zum Herstellen von Folien oder Filmen durch Aufgießen der in flüchtigen Lösungsmitteln gelösten Folienmasse auf ebene Unter lagen dienen Gießvorrichtungen, die entweder über die feststekende Unterlage bewegt werden oder bei denen bei feststehendem Gießer die Unterlage in Form eines endlosen Bandes unter dem Gießer vorbeibewegt wird. Ein derartiger Gießer besteht aus einem Vorratsbehälter für die Gießlösung, der an seinem unteren Ende eine schlitzförmige Öffnung hat, aus der die Gießlösung austritt, gegebenenfalls aus einem Abstreichlineal und Führungsmitteln, welche die gieichrnäßige Ausbreitung der Gießlösung und eine gleichmäßige Gießdicke bewirken sollen. Dieser Gießer wird zur Einhaltung eines gleichmäßigen Abstandes zwischen Abstreichlineal und Unterlage von auf der Unterlage aufliegenden Rollten getragen.Pouring device For the production of foils or films by pouring them on the film compound dissolved in volatile solvents on a flat surface Casting devices that are either moved over the fixed base or where the base in the form of an endless belt is underneath when the caster is stationary is moved past the caster. Such a caster consists of a storage container for the casting solution, which has a slit-shaped opening at its lower end, from which the casting solution emerges, if necessary from a scraper and guide means, which the uniform spreading of the casting solution and a uniform casting thickness should cause. This caster is used to maintain an even distance between the scraper ruler and the base of rollers resting on the base carried.
Als Führungsmittel für die Gießlösung beim Gießen sind u. a. an den Gießschlitzen Streifen aus Geweben, Kautschuk, Zellhorn, Metallen, Stäbe aus Metallen oder Glas, Schläuche aus Kautschuk 0. dgl. angebracht worden, die sich über die gesamte Länge der Gießschlitze erstrecken. Ferner ist es bekannt, an den seitlichen Enden der Gießschlitze feste Backen anzubringen, die entweder in die Gileßunterlage Furchen eindrücken oder in bereits in derselben vorhandenen Furchen gleiten und so eine einwandfreie seitliche Begrenzung der Folien bewirken sollen. As guide means for the casting solution during casting are, inter alia. to the Pouring slots strips of fabric, rubber, cell horn, metals, rods of metals or glass, hoses made of rubber 0 extend the entire length of the pouring slots. It is also known to the side To attach the ends of the pouring slots fixed jaws, either in the Gileßunterlage Press in furrows or slide into furrows already in the same and this should bring about a perfect lateral delimitation of the foils.
Das Vorbeiführen von Drähten an den seitlichen Enden der Gießschlitze ist ebenfalls bekannt, zwischen denen mit Hilfe eines zwj schen den Drähten angebrachten Brückenstückes die Folien in Gasen oder Fällungsbädern erzeugt werden sollen. Passing wires at the side ends of the pouring slots is also known, between which with the help of a zwj ting The bridge piece attached to the wires, the foils in gases or precipitation baths should be generated.
Die vorstehend geschilderten Verfahren sind nicht frei von Nachteilen. Das Anbringen der Streifen aus Geweben. Metallen 0. dgl. an der ganzen Länge der Gießschlitze schließt Schwierigkeiten ein, die im Werkstoit dieser Streifen, ihrer Anbringung an den Gießschlitzen und im ungleichen Verhalten xvährend des Gießens begründet sind. Bei der Anwendung fester Führungsmittel iederum fehlt infolge der Starrheit die Anpassung an die Schwankungen und betrieblichen Merungen während des Gießens. The methods outlined above are not free from disadvantages. Attaching the strips of tissue. Metals 0. the like along the entire length of the Pouring slots includes difficulties in the material of these strips, their Attachment to the pouring slots and in unequal behavior during pouring are justified. In the case of the use of fixed guide means, there is again a lack of Rigidity the adaptation to the fluctuations and operational considerations during the Pouring.
Diese Schwierigkeiten werden durch die Gießvorrichtung gemäß der Erfindung vermieden, bei der an den Enden der Gießschlitze bewegliche und drehbare Leisten als Führupgsmittel angebracht werden. Es entfallen bei der erfindungsgemäßen Vorrichtung die durch den Werkstoff und die apparativen Schwierigkeiten bedingten Nachteile der über die ganze Länge des Gießschlitzes angebrachten Streifen sowie die mangelnde Anpassung an die Schwankungen während des Gießens bei der Anwendung fester Führungsmittel. Es werden bei ihrer Anwendung Filme oder Folien von gleichbleibender Breite und Dicke erhalten. These difficulties are caused by the casting device according to FIG Invention avoided in the movable and rotatable at the ends of the pouring slots Lasts can be attached as guides. It is omitted in the case of the invention Device caused by the material and the technical difficulties Disadvantages of the strips attached over the entire length of the pouring slot as well the lack of adaptation to the fluctuations during casting in the application fixed guide means. When they are used, films or foils are more consistent Preserved width and thickness.
Die erfindungsgemäl3e Gießvorrichtung besteht darin, daß für die Führung der seitlichen Ränder der austretenden Gießlösung an den Enden des Gießschlitzes bewegliche und drehbare Führungsleisten vorgesehen sind, deren untere Enden auf der Gießunterlage gleiten. The casting device according to the invention consists in that for the Guiding the lateral edges of the emerging casting solution at the ends of the casting slot movable and rotatable guide rails are provided, the lower ends of which slide on the casting pad.
Beim Betriebe benetzt die austretende Gießlösung dicse Führungsleisten, wodurch die Zusammenziehung der Gießmasse vermieden wird. Diese Führungsmittel bestehen aus geraden oder gebogenen oder nachgebenden biegsamen Streifen von Metall 0. dgl. During operation, the emerging casting solution wets these guide strips, whereby the contraction of the casting compound is avoided. These management resources exist made of straight or curved or yielding flexible strips of metal 0.
In der Zeichnung, die ein Ausführungsbeispiel der Erfindung darstellt, bedeutet 1 den Vorratsbehälter, der an seinem unteren Ende den Gießschlitz 2 aufweist. An den Enden dieses Gießschlitzes befinden sich die beweglichen und drehbaren Führungsleisten 3, 3' für die austretende Folie 5, die auf die Gießunterlage 4 gelangt. In the drawing, which represents an embodiment of the invention, 1 means the storage container which has the pouring slot 2 at its lower end. The movable and rotatable guide strips are located at the ends of this pouring slot 3, 3 'for the emerging film 5 which reaches the casting substrate 4.
Je nachdem sich der Gießer in größerem oder kleinerem Abstand von der Gießunterlage befindet, werden die Führungsleisten 3, 3' verstellt. Depending on whether the caster is at a greater or lesser distance from the casting base is located, the guide strips 3, 3 'are adjusted.
