nahtloser Gummischläuche.seamless rubber tubing.

■ Die Erfindung betrifft ein Verfahren, um Gummischläuche, die mittels einer Schlauchpreßmaschine hergestellt werden, also nahtlos sind, auf ihrer Außenseite mit rundumlaufenden Riffelungen zu versehen. Das Verfahren gemäß der Erfindung besteht darin, daß der . aus der Presse tretende, noch plastische Schlauch von einer Riff el vorrichtung umkreist wird.. Gegenstand der Erfindung ist ferner■ The invention relates to a method to rubber hoses, which are produced by means of a hose extrusion machine, so seamlessly are to be provided with all-round corrugations on their outside. The procedure according to the invention is that the. stepping out of the press, still plastic Tube is encircled by a Riff el device .. The invention is also

ίο die zu dem angegebenen Verfahren geeignete Riffelvorrichtung. . . ■ίο the one suitable for the specified procedure Corrugating device. . . ■

In der Zeichnung zeigt Fig. ι eine Vorderansicht der Riffelvorrichtung; Fig. 2 einen Schnitt durch diese, Fig. 3 und 4 zeigen andere Ausführungsformen. In the drawing, Fig. Ι shows a front view the corrugating device; Fig. 2 shows a section through this, Figs. 3 and 4 show other embodiments.

Der zu riffelnde Schlauch entsteht durch Einpressen der durch Erwärmen weich gemachten Gummimasse in das Preßmundstück 1, in welches ein Schlauchdorn 2 hineinragt.The hose to be corrugated is created by pressing in the hose that has been softened by heating Rubber compound into the press mouthpiece 1, into which a hose mandrel 2 protrudes.

Auf dem Preßmundstück 1 ist die Riffelvorrichtung angeordnet, welche aus einer auf dem Mundstück 1 drehbar gelagerten Hülse 3 besteht, die mit einer Schnurlaufrille 4 versehen ist. An der Hülse 3, die auf dem Mundstückkörper in achsialer Richtung unverrückbar gelagert ist, befindet sich die Einrichtung zur Hervorbringung von Riffeln auf der Schlauchaußenseite. Diese Einrichtung besteht aus einem dünnen Teil 5, welcher aus Metalldraht, aus einer Feder oder auch einer Schnur bestehen kann und derart angeordnet ist, daß er unter einem gewissen, gegebenenfalls einstellbaren Druck tangential an dem | Schlauchumfang anliegt oder angedrückt wird, um die Riffeln in der noch plastischen Gummimasse hervorzubringen. Während der nahtlose Schlauch aus dem Preßmundstück austritt, wird die Riffelvorrichtung in schneller Umdrehung um den Schlauch herumgeführt, wobei durch den Riffeldraht 5 feine Rillen in dicht aneinanderliegenden Schraubenwindungen auf dem Schlauch hervorgebracht werden. On the die 1, the corrugating device is arranged, which consists of one on the Mouthpiece 1 is rotatably mounted sleeve 3, which is provided with a cord groove 4 is. On the sleeve 3 that is on the mouthpiece body is immovably mounted in the axial direction, the device for producing corrugations is located on the Hose outside. This device consists of a thin part 5, which from Metal wire, can consist of a spring or a cord and so arranged is that it is tangential to the | The circumference of the hose rests or is pressed against the corrugations in the still plastic rubber compound bring forth. As the seamless tube exits the die, the corrugation device speeds up Rotation around the hose, whereby 5 fine grooves through the corrugated wire be produced in tightly spaced screw turns on the hose.

Der Riffeldraht kann hierbei in verschiedener Weise zur Wirkung gebracht werden. In Fig. ι ist z. B. gezeigt, daß er mit einem Gewichtshebel 6 in Verbindung steht, dessen Gewicht 7 durch die bei der Drehung auftretende Fliehkraft nach außen gedrückt wird und hierdurch das Anpressen des Riffeldrahtes 5 an den Schlauch zustande kommt. Der Riffeldraht kann aber auch, wie Fig. 3 zeigt, eine Feder sein, die sich mit ihrer Federkraft gegen den Schlauch legt und mittels besonderer Stellvorrichtung in ihrer Druckwirkung beliebig einstellen läßt.The corrugated wire can be brought into effect in various ways. In Fig. Ι is z. B. shown that it is in communication with a weight lever 6, the Weight 7 is pressed outward by the centrifugal force occurring during rotation and this causes the corrugated wire 5 to be pressed against the hose. However, as FIG. 3 shows, the corrugated wire can also be a spring, which changes its spring force puts against the hose and by means of a special adjusting device in its pressure effect can be set at will.

Eine weitere Ausführungsform zeigt Fig. 4. Hier ist der Riffeldraht, der auch ein Faden sein kann, als Sehne 8 in einem verstellbaren Bügel 9 eingespannt, so daß die tangentiale Lage des Fadens und somit auch seine Druckwirkung verändert werden kann.Another embodiment is shown in Fig. 4. Here is the corrugated wire, which is also a thread can be clamped as a tendon 8 in an adjustable bracket 9, so that the tangential Position of the thread and thus also its pressure effect can be changed.

Der Schwerpunkt der Erfindung liegt in der Anordnung einer vor dem Pressemundstück kreisend angeordneten Riffelvorrichtung, welche nicht mit einem freien Ende in den GummiThe focus of the invention lies in the arrangement of a front of the press nozzle circularly arranged corrugating device, which does not have a free end in the rubber
