Description

Die Erfindung betrifft Zeltplanbahnen für das Dach und die Wände von Groß- und Festzelten, Zelthallen oder dgl., bestehend aus einem dreilagigen Bahnmaterial, bei welchem eine mittlere Gewebebahn aus hochfesten -KunststoffaserA;. insbesondere Polyesterfasern, beidseitig mit einer thermoplastischen Kunststoffolie oder -schicht abgedeckt ist und welches an seinen Längsrändern mittels Kedern hergestellte, in Profilschienen an der Trag- und Dachkonstruktion des Zeltgerüstes einziehbare Wulste aufweist, wobei die Randstreifen der Materialbahn die Keder umfassen und mit der Materialbahn verbunden, vorzugszweise verschweißt sind US-A 2 986150.The invention relates to tarpaulin sheets for the roof and walls of large and festival tents, tent halls or the like, consisting of a three-layer sheet material, in which a medium fabric sheet made of high-strength plastic fiber A ;. in particular polyester fibers, covered on both sides with a thermoplastic plastic film or layer and which has on its longitudinal edges by means of piping, beads which can be drawn into profile rails on the supporting and roof structure of the tent frame, the edge strips of the material web encompassing the piping and being connected to the material web, US-A 2 986150 is preferably welded.

Um überhaupt ein gutes Gleiten der Randwulste der Zeltplanbahnen in den Profilschienen des Zeltgerüstes beim Auf- bzw. Abbau der Zelte oder dgl. zu gewährleisten, hat es sich als zweckmäßig erwiesen, die Oberfläche der Randwulste und auch die der angrenzenden Zeltplanbahn in einem relativ schmalen Bereich mit einem textilen Gewebestreifen zu kaschieren, da die glatten Oberflächen der äußeren Kunststoffschicht einen verhältnismäßig hohen Reibungskoeffizient gegenüber den aus Metall bestehenden Profilschienen haben. Derart kaschierte Randwulste gleiten aber problemlos und gut in den Profilschienen. Andere Maßnahmen zur Lösung dieses Problems haben sich nicht bewährt.In order to ensure a good sliding of the edge beads of the tarpaulin sheets in the profile rails of the tent scaffold when setting up or dismantling the tents or the like, it has proven to be expedient to keep the surface of the edge beads and also that of the adjacent tent sheet in a relatively narrow area to be laminated with a textile fabric strip, since the smooth surfaces of the outer plastic layer have a relatively high coefficient of friction compared to the profile rails made of metal. Edge beads of this type glide easily and smoothly in the profile rails. Other measures to solve this problem have not worked.

Zur Herstellung der vorbekannten Zeltplanbahnen der in Betracht kommenden Art hat man bisher im wesentlichen zwei Methoden angewandt. Bei der einen hat man separat ein Kederband hergestellt und dessen Fahnen dann mit der Zeltplanbahn verschweißt.So far, essentially two methods have been used to produce the previously known tarpaulin sheets of the type in question. One of them made a keder tape separately and then welded its flags to the tarpaulin membrane.

Bei der zweiten Methode wurde die Materialbahn an ihren Längsrändern zunächst mit einem Keder versehen und dann der Randstreifen mit dem Wulst mit einem Gewebeband überzogen.In the second method, the material web was first provided with a piping on its longitudinal edges and then the edge strip with the bead was covered with a fabric tape.

Der Aufwand bei der Herstellung der vorbeschriebenen, bisher gebräuchlichen Zeltplanbahnen ist beträchtlich. Er beruht vor allem auf der Notwendigkeit mehrerer Arbeitsgänge und dem Erfordernis paßgenauer Ver- und Bearbeitung.The effort involved in the manufacture of the previously described tent tarpaulin sheets is considerable. It is based above all on the need for several work steps and the need for precise machining and processing.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung der in Betracht kommenden Zeltplanbahnen zu vereinfachen und zu rationalisieren, um die Kosten des Fertigprodukts zu senken.The invention has for its object to simplify and rationalize the manufacture of the tarpaulin sheets in question in order to reduce the cost of the finished product.

Zur Lösung der vorgenannten Aufgabe wird gemäß der Erfindung vorgeschlagen, für die Zeltplanbahnen eine mehrschichtige Materialbahn zu verwenden, bei welcher die Längsränder entweder auf der Oberseite oder auf der Unterseite frei von der die mittlere Gewebeschicht abdeckenden Kunststoffschicht sind und die Keder zur Bildung des Wulstrandes derart umspannen, daß an ihnen die Kunststoffschicht des Randstreifens unmittelbar anliegt.To achieve the aforementioned object, it is proposed according to the invention to use a multilayer material web for the tarpaulin sheets, in which the longitudinal edges are free of the plastic layer covering the middle fabric layer either on the top or on the underside and span the piping in such a way to form the beaded edge that the plastic layer of the edge strip lies directly on them.

Weitere Merkmale erfindungsgemäß ausgebildeter Zeltplanbahnen gehen aus den Unteransprüchen und aus der nachstehenden Beschreibung der in den Figuren 1 bis 6 dargestellten bevorzugten Ausführungsbeispele hervor. Es zeigen:

  • Fig. 1 einen Querschnitt einer Materialbahn zur Herstellung der Zeltplanbahn in einer ersten Ausführungsform;
  • Fig. 2 einen Querschnitt durch den Randstreifen einer Zeltplanbahn, für die die Materialbahn nach Fig. 1 verwendet worden ist;
  • Fig. 3 einen Querschnitt durch den Randbereich einer Materialbahn in einer zweiten Ausführungsform;
  • Fig. 4 einen Querschnitt durch den Randstreifen einer Materialbahn in einer dritten Ausführungsform;
  • Fig. 5 einen Querschnitt durch den Randbereich einer Zeltplanbahn unter Verwendung der Materialbahn nach Fig. 4;
  • Fig. 6 einen Querschnitt durch den Randbereich einer Zeltplanbahn unter Verwendung eines Keders mit einer neuartigen Querschnittsform.
Further features of tarpaulin sheets designed according to the invention are evident from the subclaims and from the following description of the preferred exemplary embodiments shown in FIGS. 1 to 6. Show it:
  • 1 shows a cross section of a material web for producing the tarpaulin sheet in a first embodiment;
  • FIG. 2 shows a cross section through the edge strip of a tarpaulin sheet, for which the material sheet according to FIG. 1 has been used;
  • 3 shows a cross section through the edge region of a material web in a second embodiment;
  • 4 shows a cross section through the edge strip of a material web in a third embodiment;
  • 5 shows a cross section through the edge region of a tarpaulin sheet using the material sheet according to FIG. 4;
  • Fig. 6 shows a cross section through the edge region of a tarpaulin sheet using a welt with a novel cross-sectional shape.

Wie aus Fig. 1 ersichtlich, besteht die zur Herstellung einer Zeltplanbahn der in Betracht kommenden Art zu verwendende Materialbahn 1 in an sich bekannter Weise aus einer mittleren Gewebeschicht 12, die beiderseits mit einer Kunststoffschicht 13 bzw. 14 versehen ist. Im dargestellten Fall reicht die an der Unterseite der Gewebeschicht 12 befindliche Kunststoffschicht nicht bis zum Rand 15 der Materialbahn, so daß das Gewebe der mittleren Schicht 12 längs eines Randstreifens 16 von Kunststoff frei ist.As can be seen from FIG. 1, the material web 1 to be used for producing a tarpaulin sheet of the type in question is made in a manner known per se from a middle fabric layer 12, which is provided on both sides with a plastic layer 13 or 14. In the case shown, the plastic layer located on the underside of the fabric layer 12 does not extend to the edge 15 of the material web, so that the fabric of the middle layer 12 along an edge strip 16 is free of plastic.

Bei der Verarbeitung der derart ausgebildeten Materialbahn 11 ist, wie Fig. 2 erkennen läßt, deren Rand von unten nach oben um das aus einem flexiblen Kunststoffprofil bestehende Keder 17 herumgelegt, so daß die Kunststoffschicht 13 der Oberseite der Materialbahn 11 an dem Keder 17 an- sowie auf ihr selbst aufliegt und ist sowohl mit dem Keder 17 als auch mit sich selbst durch Verschweißung verbunden.2, the edge of which is laid around the piping 17 consisting of a flexible plastic profile, so that the plastic layer 13 on the upper side of the material web 11 is attached to the piping 17. and rests on it and is connected to the piping 17 as well as to itself by welding.

Eine weitere Ausführungsform geht aus den Figuren 4 und 5 hervor. Bei dieser ist der Rand 20 der mittleren Gewebeschicht 12" im Bereich eines Streifens 21 seitlich der Kante 22 nicht mit Kunststoff abgedeckt, damit die Gewebeschicht 12" im Bereich des durch den Keder 17" gebildeten Wulstes frei liegt und ein gutes Gleiten in der Profilschiene gewährleistet ist.Another embodiment is shown in FIGS. 4 and 5. In this case, the edge 20 of the middle fabric layer 12 "in the area of a strip 21 to the side of the edge 22 is not covered with plastic, so that the fabric layer 12" is exposed in the area of the bead formed by the piping 17 "and ensures good sliding in the profile rail is.

Der bei dieser Ausführungsform verbleibende Randstreifen 23 der unteren Kunststoffschicht 14", der gegebenenfalls auch noch nach außen über die Kante 22 hinausragen kann, deckt bei der fertigen Zeltplanbahn den umgeschlagenen Randstreifen und insbesondere das Gewebe weitgehend ab, um ihn wie auch die Kante 22 gegen Verrottung zu schützen. Wenn auch das Gewebe aus aus Kunststoffasern bestehenden Fäden hergestellt ist, so unterliegt es doch, wenn es ständig jedweden Witterungseinflüssen ausgesetzt ist, im Laufe der Zeit unterschiedlichsten zerstörerischen Einflüssen. Durch den nach außen überragenden Rand wird zusätzlich die Kante 22 geschützt.The edge strip 23 of the lower plastic layer 14 ″ remaining in this embodiment, which can possibly also protrude outward beyond the edge 22, largely covers the folded edge strip and in particular the fabric around the finished tarpaulin sheet, around it and the edge 22 against rotting Even if the fabric is made of threads made of plastic fibers, if it is constantly exposed to all weather influences, it is subject to a variety of destructive influences over time. The edge 22 is additionally protected by the outwardly projecting edge.

Bei der Herstellung des Randwulstes an den Längskanten der Zeltplanbahnen wird zweckmäßigerweise nicht nur der umgeschlagene Rand mit der Materialbahn, sondern dieser dabei gleichzeitig auch mit dem Keder verschweißt. Das die zu verschweißenden Oberflächen aufheizende und ausschmelzende Heizwerkzeug erfaßt hierzu auch den benachbarten Teil des Keders.In the manufacture of the edge bead on the longitudinal edges of the tarpaulin sheets, not only the folded edge with the material sheet is expediently used, but this at the same time also welded to the piping. The heating tool which heats and melts the surfaces to be welded also covers the adjacent part of the piping.

Da bei Anwendung von Hochfrequenzschweißgeräten und -werkzeugen die Verschweißung des Keders mit der Materialbahn schwierig ist, ist es hierfür vorteilhaft, einen Keder 24 zu verwenden, der mit einer Schweißfahne 25 versehen ist. Über diese wird eine gute und feste Verbindung der Materialbahn 26 mit dem Keder 24 mit Sicherheit erhalten.Since it is difficult to weld the piping to the material web when using high-frequency welding devices and tools, it is advantageous to use a piping 24 which is provided with a welding vane 25. A good and firm connection of the material web 26 to the piping 24 is reliably obtained via this.

Bei der Verwendung der vorbeschriebenen, erfindungsgemäß ausgebildeten Materialbahnen bedarf es keiner besonderen Arbeitsgänge, um an bzw. auf den Randwulsten der Zeltplanbahnen eine gleitfähige Oberfläche mit entsprechend niedrigem Reibungskoeffizienten anzubringen, da diese bereits von der Materialbahn selbst geboten wird.When using the above-described material webs designed according to the invention, no special work steps are required in order to apply a slidable surface with a correspondingly low coefficient of friction to or on the edge beads of the tent sheet webs, since this is already provided by the material web itself.
