Description

Vorrichtung zum Formen und Verschließen von Be- und Entwässerungsrohren aus Kunststoffolienstreifen Die Erfindung betrifft eine Vorrichtung zum Formen und Verschließen von Be und Entwässerungsrohren aus Kunststoffolienstreifen.Device for forming and closing irrigation and drainage pipes from plastic film strips The invention relates to a device for molding and Sealing of water and drainage pipes made of plastic film strips.

Es sind Vorrichtungen zum Formen und Verschließen von Be- und Entwässerungsrohren aus Kunststoffolienstreifen bekannt, bei denen in einer geheizten Ziehform das Material allmählich aufgerundet und durch die Wärmeeinwirkung plastisch verformt wird. They are devices for forming and closing irrigation and drainage pipes known from plastic film strips, in which the material is in a heated drawing form is gradually rounded up and plastically deformed by the action of heat.

Das Verlegen im Boden der unter Warmverformung hergestellten Be- und Entwässerungsrohre in einen nach dem Maulwurfsprinzip hergestellten Hohlgang bereitet große Schwierigkeiten, da die Einhaltung der gleichmäßig erforderlichen Verformungstemperatur nicht gewährleistet ist. Außerdem werden zur Warmverformung kostspielige Aggregate benötigt. The laying in the floor of the products manufactured under hot deformation and drainage pipes into a hollow passage made according to the mole principle causes great difficulty, as compliance with the uniformly required Deformation temperature is not guaranteed. They are also used for hot deformation expensive aggregates are required.

Des weiteren sind Vorrichtungen bekanntgeworden, mittels deren die zu Rohren geformten Kunststofffolienstreifen wahlweise geschweißt, geklebt oder geklammert werden. Von Mangel ist, daß für das Schweißen, Kleben oder Klammern ein kompliziertes Rohrformwerk benötigt wird, das infolge seiner zahlreichen bewegten Teile unter den Bedingungen der unterirdischen Arbeit sehr störanfällig ist und die Qualität beeinträchtigt. Ein weiterer Mangel ist, daß derartige vom Fahrantrieb der Maschine gesteuerte Formvorrichtungen viel Platz benötigen und es unmöglich machen, daß das geformte Rohr, ohne vorher den Graben auszuheben, in den Boden verlegt werden kann. Furthermore, devices have become known by means of which the Plastic film strips formed into tubes, optionally welded, glued or be bracketed. The deficiency is that for welding, gluing or stapling Complicated Rohrformwerk is required, which moved as a result of its numerous Parts under the conditions of underground work is very prone to failure and affects the quality. Another shortcoming is that such from the drive machine-controlled molding devices take up a lot of space and it is impossible make that the formed pipe is laid in the ground without first digging the trench can be.

Aufgabe der Erfindung ist es, die vorgenannten Mängel zu beseitigen und eine Vorrichtung zum Formen und Verschließen von Be- und Entwässerungsrohren zu schaffen, deren konstruktive Gestaltung es gestattet, daß die an den äußeren Kanten mit T-förmigen Aussparungen versehenen Kunststofffolienstreifen derart geformt werden, daß sich die Aussparungen infolge der Elastizität der Folie mit starker Spannung gegenüberliegen und beim Austritt aus der Vorrichtung ineinanderhaken. The object of the invention is to eliminate the aforementioned shortcomings and a device for forming and closing irrigation and drainage pipes to create whose structural design allows that to the outer Plastic film strips provided with edges with T-shaped recesses are shaped in this way be that the recesses due to the elasticity of the film with stronger Opposite tension and hook into each other when exiting the device.

Erfindungsgemäß wird das erreicht, indem die Führung am Materialaustritt zu zwei unmittelbar nebeneinanderliegenden geschlossenen Ösen eingerollt ist und die Enden der Ösen parallel zur Symmetrieebene der Führung ausgerichtet sind. According to the invention this is achieved by the guide at the material outlet is rolled up to two immediately adjacent closed eyelets and the ends of the eyelets are aligned parallel to the plane of symmetry of the guide.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt F i g. 1 eine Draufsicht der Vorrichtung, F i g. 2 eine Seitenansicht der Vorrichtung, F i g. 3 eine Vorderansicht der unmittelbar nebeneinanderliegenden geschlossenen Ösen. An exemplary embodiment of the invention is shown in the drawing. It shows F i g. 1 shows a plan view of the device, FIG. 2 is a side view of FIG Device, FIG. 3 is a front view of the immediately adjacent closed eyelets.

Der Erfindungsgegenstand besteht aus einer Führung 1, die an den Seiten angeordnete, vom Materialeinlauf bis in unmittelbarer Nähe des Materialaustritts sich erstreckende, an sich bekannte Falze 2, 3 aufweist. Die Führung 1 ist kontinuierlich von beiden Seiten derart eingerollt, daß sich selbige in eine Richtung verjüngt und in Nähe der Falzenden 4, 5 zwei unmittelbar nebeneinanderliegende geschlossene Ösen 6 bildet. Die äußeren Enden 7, 8 der Ösen 6 sind parallel zur Symmetrieebene der Führung 1 ausgerichtet. Die mit T-förmigen Aussparungen versehenen Kunststoffolienstreifen werden in die Führung 1 eingelegt und nehmen beim Durchlauf durch die Führung 1 einen nahezu geschlossenen Querschnitt an. Beim Austritt der Folie aus den Falzenden 4, 5 werden die Kanten der mit T-förmigen Aussparungen versehenen Folie 9 von den Enden 7, 8 der Ösen derart zusammengeführt, daß dieselben beim Austritt aus den geschlossenen Ösen 6 infolge ihrer Elastizität fest miteinander verhakt werden und ein verschlossenes Rohr mit Kreisquerschnitt bilden. The subject matter of the invention consists of a guide 1, which is attached to the Sides arranged, from the material inlet to the immediate vicinity of the material outlet extending folds 2, 3 known per se. Leadership 1 is continuous rolled up on both sides in such a way that it tapers in one direction and in the vicinity of the fold ends 4, 5, two closed ones immediately adjacent to one another Eyes 6 forms. The outer ends 7, 8 of the eyelets 6 are parallel to the plane of symmetry the guide 1 aligned. The plastic film strips with T-shaped recesses are placed in the guide 1 and take as they pass through the guide 1 an almost closed cross-section. When the film emerges from the fold ends 4, 5, the edges of the T-shaped recesses provided with film 9 of the Ends 7, 8 of the eyelets brought together so that the same when exiting the closed eyelets 6 are firmly hooked together due to their elasticity and form a closed tube with a circular cross-section.
