Abstract

Bei Vorrichtungen, bei denen mindestens ein umlaufendes Preßband an die Werkstoffbahn von einem Druckmittel anpreßbar ist, das in ein mittels eines Dichtungsrahmens abgedichtetes Druckkissen ein­ geleitet wird, treten zwischen dem rechteckförmigen Dichtungsrahmen und dem Preßband Undichtigkeiten im Bereich der Ablaufseite des Pro­ duktes auf. Diese sind darauf zurückzuführen, daß das Produkt der Vor­ richtung in hartem Zustand zugeführt, unter dem Einfluß von Wärme in einen weichen Zustand übergeführt wird, insbesondere im Längsrandbe­ reich seine Form ändert und unter Abkühlung abbindet. Die Aufgabe be­ steht darin, die Vorrichtung so zu gestalten, daß durch das Druckkis­ sen der volle Arbeitsdruck dem Produkt aufgegeben wird und die Undich­ tigkeiten zwischen dem Druckkissen und dem zugeordneten Preßband durch Verformung des Produktes vermieden werden. For devices in which at least one rotating Press belt can be pressed onto the material web by a pressure medium that into a pressure cushion sealed by means of a sealing frame is passed between the rectangular sealing frame and the press belt leaks in the area of the discharge side of the Pro duktes. These are due to the fact that the product of the pre direction in the hard state, under the influence of heat in a soft condition is transferred, especially in the longitudinal edge rich changes its shape and sets under cooling. The task be is to design the device so that by the Druckkis the full working pressure is given to the product and the activities between the pressure pad and the associated press belt Deformation of the product can be avoided.

Der erfindungsgemäße Dichtungsrahmen (1) weist im Grundriß an der Zuführseite der Werkstoffbahn (8) eine größere Breite als an der Ab­ laufseite der Werkstoffbahn auf. The sealing frame according to the invention (1) has in plan on the Feed side of the material web (8) has a greater width than at the Ab running side of the material web.
