Abstract

Longitudinal edges of woven fabrics are joined together with an adhesive or thermowelding seam using a tape which is laid under the seam. Tape prevents egress of extruded adhesive or plastics material through the underside of the fabric. Pref. the flat fabric strip is folded into the tube and the overlapping edges are joined together at their interface using the extruded strip. The tape, which may be a plastic or a densely woven tape, is laid on the inner wall of the tube. Tape may be supplied from a storage roll.

Description

Längsnahtbildung bei GewebenLongitudinal seam formation in fabrics

Die Erfindung betrifft ein Verfahren zum Verbinden von Geweben miteinander mittels eine extrudierten Fadens.The invention relates to a method for joining fabrics to one another by means of an extruded thread.

Bei einem durch die US-PS 3 578 543 bekanntgewordenen Verfahren dieser Art sind die zu verbindenden Gewebe gegenseitig mit Plastikfolien beschichtet. Der extrudierte Faden kommt daher mit dem Gewebe nicht in Berührung, sondern verbindet die untere Plastikfolie des obenliegenden Gewebes mit der oberen Plastikschicht des unten liegenden Gewebes. Das vorbekannte Verfahren hat den Nachteil, daß der extrudierte Faden nicht die Gewebe selbst miteinander verbindet. Die Verbindung der beiden Gewebe weist maximal die Festigkeit auf, mit der die Plastikfolien und das Gewebe verbunden sind.In a process made known by US Pat. No. 3,578,543, this Art, the tissues to be joined are mutually coated with plastic sheeting. Of the extruded thread therefore does not come into contact with the fabric, but rather connects it the lower plastic sheet of the fabric on top with the upper plastic layer of the underlying tissue. The previously known method has the disadvantage that the extruded thread does not bind the fabrics together by itself. The connection of the two fabrics has a maximum of the strength with which the plastic films and the tissues are connected.

Durch die DT-OS 1 704 345 ist es bekannt, zwei Bahnen aus Gewebe oder Folie aufeinanderzulegen und durch einen extrudierten Faden miteinander zu verbinden. Bei-der dort gezeigten Vorrichtung wird eine flache Bahn zu einem Schlauch gefaltet und die Längskanten durch eine Naht mittels eines extrudierten Fadens verbunden. Diese Vorrichtung weist den Nac hse; I t Wu c r der auf die Bahnen extrudierte Faden infolge des Eigengewichtes nach unten absinkt. Die Naht muß außerdem gepreßt werden, solange sie plastisch ist, wodurch das Æateriasl durch das Gewebe dringt und sich mit dem darunterliegenden Trenn- oder Formatblech oder mit der Geenüberliegenden Schlauchwand verbindet, so daß oft unliebsame Haschinenstillstände eintreten bzw. der Schlauch unbrauchbar wird. Aus diesem Grund werden bis heute unbeschichtete Gewebe nicht geklebt, sondern genäht.From DT-OS 1 704 345 it is known to lay two webs of fabric or film on top of one another and to connect them to one another by an extruded thread. In the device shown there, a flat web is folded into a tube and the longitudinal edges are connected by a seam by means of an extruded thread. This device has the Neck; I t Wu cr der Thread extruded onto the webs sinks downwards as a result of its own weight. The seam must also be pressed as long as it is plastic, whereby the Æateriasl penetrates through the tissue and connects to the underlying partition or format sheet or to the hose wall above the geen, so that unpleasant machine stoppages often occur or the hose becomes unusable. For this reason, to this day, uncoated fabrics are not glued, but sewn.

Aufgabe der Erfindung ist es daher, ein Verfahren anzugeben, das ein Durchschlagen des Klebematerials durch das Gewebe vermeidet.The object of the invention is therefore to provide a method that a Avoids penetration of the adhesive material through the fabric.

Je Aufgabe ist erfindungsgemäß dadurch gelost, daß unter die Klebe-bzw. Schweißnaht ein Streifen untergelegt, d.h., in den Schlauch eingelegt wird.According to the invention, each task is solved in that under the adhesive or. A strip is placed underneath the weld seam, i.e. inserted into the hose.

Durch den Streifen wird ein Durchschlagen des Klebestoffes verhindert und vorteilhafterweise auch eine gute Umklammerunfr des Gewebes durch den Klebstoff erreicht, so daß dadurch die Festigkeit der Naht erheblich gesteigert wird, ohne daß das Gewebematerial selbst beschädigt wird, was eintreffen würde, wenn das extrudierte Material das Gewebe infolge zu hoher Temperatur anschmelzen würde.The strip prevents the adhesive from penetrating and advantageously also good clasping of the tissue by the adhesive achieved, so that the strength of the seam is significantly increased without that the fabric material itself is damaged, which would happen if the extruded Material would melt the fabric as a result of excessive temperature.

Vorzugsweise wird der einzulegende Streifen von einer Vorratsrolle abgezogen. Dadurch wird ein nahezu kontinuierlicher Betrieb ermöglicht.The strip to be inserted is preferably from a supply roll deducted. This enables almost continuous operation.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher erlutert. Sie zeigt eine Draufsicht auf eine flachliegende Bahn, die zu einem Schlauch gefaltet und dessen ASnuer miteinander verklebt werden. Ein flachliezendes gewebe 1 wird durch eine nicht dargestellte Vorrichtun, zu einem Schlauch 2 gefaltet. Seine Ränder 3, 4 liegen übereinander. Durch eine Düse 5 wird ein Kleb- oder Schweißfaden 6 extrudiert, der beide Ränder 3, 4 miteinander verklebt. Gegen das Durchschlagen des extrudierten Klebe- oder Schweißmaterials nach unten wird von einer Vorratsrolle 7 ein schmaler Streifen S abgezogen und unter den zu verklebenden unteren Rand eingelegt. Dieser Streifen 8 verklebt mit der unteren ahn. Ein weiteres Absinken des Klebematerials nach unten wird durch den Streifen 3 verhindert. Dadurch kann das aufgebrachte Klebe- oder Schweinmaterial das Gewebe innig umklammern und die Verbindung der beiden Lagen verbessern.An embodiment is shown in the drawing and will in the the following is explained in more detail. It shows a top view of a flat web, which are folded into a tube and its ASnuer glued together. A Flat-lying tissue 1 is turned into one by a device not shown Tube 2 folded. Its edges 3, 4 are on top of each other. Through a nozzle 5 is an adhesive or welding thread 6 is extruded, which glues both edges 3, 4 together. Against penetration of the extruded adhesive or welding material downwards a narrow strip S is drawn off from a supply roll 7 and under the to adhesive lower edge inserted. This strip 8 is glued to the lower one ahn. Another downward sinking of the adhesive is caused by the strip 3 prevented. This allows the adhesive or pig material applied to the tissue Clasp tightly and improve the connection between the two layers.

Der Streifen 8 kann aus einer Kunststoffolie, einem dichten Gewebe oder auch anderen Materialien bestehen.The strip 8 can be made of a plastic film, a dense fabric or other materials.
