Patentschrift weicht von der Auslegeschrift abThe patent specification differs from the patent specification

Die Erfindung bezieht sich auf eine Vorrichtung zum beidseitigen Beschichten von Trägerbahnen mit thermoplastischen Kunststoffen, bei der die Trägerbahn beidseitig beschichtbar, innerhalb eines Gelierkanals gelierbar und in einer Kühlvorrichtung kühlbar ist.The invention relates to a device for the coating of carrier webs on both sides thermoplastics, in which the carrier web can be coated on both sides, within a gelation channel is gellable and coolable in a cooling device.

Es wurde bereits vorgeschlagen, auf einer Seite der vertikal geführten Trägerbahn unterhalb von Bahnführungswalzen eine Beschichtungsrakel vorzusehen, wobei die Trägerbahn selbst an oder nahe an dieser Beschichtungsstelle auf der Gegenseite durch eine Gegenstütze abgestützt ist, während die zweite Beschichtungsrakel unmittelbar unterhalb dieser letzten Gegenstütze vor Einlauf in den Gelierkanal angeordnet ist.It has already been proposed on one side of the vertically guided carrier web below Web guide rollers provide a coating knife, with the carrier web itself at or near is supported at this coating point on the opposite side by a counter support, while the second Coating doctor arranged directly below this last counter support before entering the gelation channel is.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Vorrichtung zum beidseitigen Beschichten von Trägerbahnen mit thermoplastischen Kunststoffen je eine Beschichtungsrakel auf beiden Seiten der senkrecht geführten Trägerbahn so anzuordnen, daß eine »0 zusätzliche Gegenstütze entfallen kann. Die Erfindung besteht darin, daß beide Beschichtungsrakeln unter Wegfall der Gegenstütze auf gleicher Höhe angeordnet sind.The invention is based on the object of a device for the double-sided coating of Carrier webs with thermoplastics each have a coating doctor blade on both sides of the vertical to arrange the guided carrier web in such a way that an »0 additional counter support can be omitted. The invention consists in the fact that both coating doctor blades are arranged at the same height with the omission of the counter support are.

Auf diese Weise wird erreicht, daß die Schichtstärken auf beiden Seiten der Trägerbahn gleich sind, weil der Trägerbahn keine Gelegenheit gegeben wird, nach der einen oder der anderen Seite beim Beschichtungsvorgang auszuweichen, wobei gleichzeitig eine Gegenstütze entfallen kann.In this way it is achieved that the layer thicknesses are the same on both sides of the carrier web, because the carrier web is not given an opportunity to go one side or the other in the coating process to evade, while at the same time a counter support can be omitted.

Die durch die Vorrichtung erfüllte Gewähr einer gleichen Schichtstärke auf beiden Bahnseiten wirkt sich in ebenso günstiger Weise auf die Ware selbst aus, insbesondere dann, wenn sie noch in nachfolgenden Nachbehandlungseinrichtungen nachbehandelt werden muß. Man erhält durch die Garantie einer beidseitig gleichen Schichtstärke eine völlig gleichmäßig ausgebildete Ware, die nicht zuletzt auch im nachfolgenden Gelierungsprozeß besser behandelt werden kann, da man nicht mit abweichenden Schichtstärken auf einer der beiden Bahnseiten rechnen muß. Man kann somit den Gelierkanal so einstellen, daß er auf nur gleiche Schichtstärken gelierend einzuwirken hat. So wird auch die Gelierung an sich zuverlässiger und sicherer durchgeführt.The guarantee of the same layer thickness fulfilled by the device acts on both sides of the web in an equally favorable manner on the goods themselves, especially if they are still in subsequent Post-treatment facilities must be post-treated. The guarantee gives you a The same layer thickness on both sides results in a completely uniform product, which not least also in the subsequent gelation process can be treated better, since one does not have to use different layer thicknesses must count on one of the two sides of the track. You can thus adjust the gelation channel so that he only has a gelling effect on layers of the same thickness. This also makes the gelation itself more reliable and carried out more safely.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel dargestellt.The subject matter of the invention is shown in an exemplary embodiment in the drawing.

Die Trägerbahn 10 läuft von einem Vorrat 11 ab und gelangt zunächst über ein Führungswalzenpaar 12 in den unmittelbaren Bereich der beiden sich in gleicher Höhe gegenüberliegenden Beschichtungsrakeln 13 und 15. Auf diese Weise wird die Träger-Vorrichtung zum beidseitigen Beschichten von
TrägerbahnenThe carrier web 10 runs off a supply 11 and first arrives via a pair of guide rollers 12 in the immediate area of the two opposite coating blades 13 and 15 at the same height

bahn 10 gleichzeitig auf beiden Seiten mit einem Schichtauftrag versehen. Nach der Beschichtung der Trägerbahn 10 erfolgt in einem Gelierkanal 16. der über seine gesamte Länge hinweg mit in gegenüberliegender Anordnung vorgesehenen Infrarotheizstrahlern 17, 18 versehen ist, die eigentliche Gelierung der Trägerbahn 10, die ihrerseits den Gelierkanal 16 frei vertikal durchläuft und erst nach der Gelierung, d. h. hinter dem Gelierkanal 16, erneut wieder von Walzen erfaßt wird.Web 10 is provided with a layer application on both sides at the same time. After coating the Carrier web 10 takes place in a gelation channel 16. which is opposite over its entire length Arrangement provided infrared heaters 17, 18 is provided, the actual gelation of the Carrier web 10, which in turn freely runs vertically through the gelling channel 16 and only after gelling, d. H. behind the gelation channel 16, is again detected by rollers.

Über eine Umlenkwalze 22 gelangt die beiderseits beschichtete und bereits gelierte Bahn in den Bereich einer Kühleinrichtung 23 bis 25, in der die Bahn derart umgelenkt wird, daß beide Seiten nacheinander einem Kühlprozeß unterzogen werden, bis schließlich bei 26 die endgültige Aufwicklung der fertigen Ware erfolgt.The web, which is coated on both sides and already gelled, arrives in the area via a deflection roller 22 a cooling device 23 to 25, in which the web is deflected in such a way that both sides one after the other be subjected to a cooling process until finally at 26 the final winding of the finished goods he follows.
