Description

Herstellung von biegsamen Bändern, Folien oder Schläuchen aus Polystyrol o. dgl. Im Hauptpatent sind ein `'erfahren zur Herstellung von biegsamen Bändern, Folien und Schläuchen aus Polymerisationsprodukten von Arylolefinen, insbesondere Polystyrol, und eine Vorrichtung zur Ausübung dieses Verfahrens beschrieben. Das Verfahren nach dein Hauptpatent besteht darin, daß die Kunstmasse in erwärmtem Zustand aus einer ringförmigen. Düse ausgespritzt und über eine am Mittelstück der Düse angebrachte Spreizvorrichtung gezogen wird. Hierbei wird die ausgespritzte Masse einer allseitigen Reckung unterworfen, und es wird erreicht, daß der entstehende Schlauch und die daraus geschnittenen Bänder und-Folien in jeder Richtung biegsam und nachgiebig sind.Manufacture of flexible tapes, foils or tubes made of polystyrene or the like. In the main patent are an '' experienced in the production of flexible tapes, Films and tubes made from polymerization products of aryl olefins, in particular Polystyrene, and an apparatus for practicing this method are described. That Method according to your main patent is that the synthetic material in a heated state from an annular. Sprayed out nozzle and via one on the center piece of the nozzle attached spreader is pulled. This is where the mass sprayed out subjected to an all-round stretching, and it is achieved that the resulting Hose and the tapes and foils cut from it are flexible in every direction and are compliant.

l3in Nachteil des Verfahrens nach dein Flauptpatent besteht darin, daß die Kanten der Bänder, die über die Rollen der Spreizvorrichtung gelaufen sind, abgeschnitten werden müssen und abfallen, und daß die Schläuche an dieser Stelle nicht glatt sind. Gegenstand der Erfindung ist ein Verfahren zur Herstellung von biegsamen Bändern. Folien und Schläuchen aus den im Hauptpatent genannten Stoffen und eine Vorrichtung zur Ausübung dieses Verfahrens, die den obengenannten Nachteil vermeidet und sich darüber hinaus durch größte Einfachheit, Zweckmäßigkeit und Betriebssicherheit auszeichnet. Erfindungsgemäß erfolgt die Aufweitung des aus der ringförmigen Düse gespritzten Schlauches nicht durch eine mechanische Spreizvorrichtung, sondern mittels Preßluft.The disadvantage of the procedure according to your Flaupt patent is that that the edges of the tapes that have run over the rollers of the spreader, need to be cut off and fall off, and that the tubing is at this point are not smooth. The invention is a process for the production of flexible straps. Films and tubes made from the substances mentioned in the main patent and an apparatus for practicing this method which has the aforementioned disadvantage avoids and also through the greatest simplicity, practicality and operational reliability excels. According to the invention, the expansion takes place from the annular nozzle sprayed hose not by a mechanical spreading device, but by means of Compressed air.

Es ist bekanntgeworden, Schläuche aus Viscose oder ähnlichen, nicht von selbst erhärtenden Stoffen in der Ouerrichtung in geringem Maße durch Druckluft auszuweiten. um die mechanische Zähigkeit derartiger Schläuche zu steigern. Nach der Erfindung werden jedoch Schläuche aus Polystyrol u. dgl. zwecks Erzielung einer ausreichenden Biegefähigkeit unter gleichzeitiger Reckung in der Längsrichtung mittels Preßluft in starkem Maße ausgeweitet.It has become known that hoses made of viscose or similar are not of self-hardening substances in the Ouerrichtung to a small extent by compressed air to expand. to increase the mechanical toughness of such hoses. To of the invention, however, tubes made of polystyrene and the like for the purpose of achieving a sufficient flexibility with simultaneous stretching in the longitudinal direction by means of Compressed air expanded to a large extent.

In der Abbildung ist eine Vorrichtung zur Ausübung dieses Verfahrens in einer beispielsweisen Ausführungsform dargestellt. Die in der Presse i befindliche Kunstmasse wird erwärmt und durch die ringförmige Düse :2 als Schlauch 3 ausgespritzt. Der Schlauch tritt sodann in das Innere eines Begrenzungsrohres 5 ein, dessen Durchmesser in dem an die Düse anschließenden Teil stetig zunimmt. Durch einen Kanal 4. innerhalb der Düse wird Preßluft zugeführt, die den Schlauch an die Wandungen des Begrenzungsrohres 5 preßt und dabei eine allseitige Reckung der Kunstmasse hervorruft. Nachdem der Schlauch abgekühlt ist, tritt er an der Stelle 6 aus dem Begrenzungsrohr 5 heraus und wird durch zwei Guininiwalzen 7 flach 'zusammengepreßt. Hierdurch wird erreicht, daß die durch das Rohr 4. eintretende Preßluft nicht am anderen Ende des Schlauches entweichen kann. Hinter den Gummiwalzen 7 befindet sich zweckmäßig eine Schneidevorrichtung 8, die die beiden Kanten des zusammengedrückten Schlauches aufschneidet. Dabei entstehen zwei Folien 9, die auf Vorratstrommeln so aufgewickelt tverden können.In the picture is an apparatus for performing this procedure shown in an exemplary embodiment. The one in the Press i located plastic is heated and through the annular nozzle: 2 as Hose 3 sprayed out. The hose then enters the interior of a limiting tube 5, the diameter of which increases steadily in the part adjoining the nozzle. Compressed air is fed through a channel inside the nozzle, which feeds the hose presses against the walls of the limiting tube 5 while stretching on all sides the art mass evokes. After the hose cools down, it kicks in place 6 out of the limiting tube 5 and is pressed together flat 'by two Guinini rollers 7. This ensures that the compressed air entering through the pipe 4 is not on the the other end of the hose can escape. Behind the rubber rollers 7 is located expediently a cutting device 8, the two edges of the compressed Hose cuts open. This results in two foils 9 that are placed on storage drums can be wrapped up in this way.
