Verfahren zum Verbinden einer Schlauchbahn mit einem diese umgebenden RundgewebeschlauchMethod of connecting a hose web to a this surrounding tubular fabric

Die Erfindung betrifft ein Verfahren zum Verbinden einer Schlauchbahn oder eines Schlauchabschnitts mit einem diese oder diesen umgebenden Rundgewebeschlauch oder -abschnitt.The invention relates to a method for connecting a hose web or a hose section to one of these or this surrounding tubular fabric tube or section.

In der älteren Patentanmeldung P 31 11 829.1 ist eine Vorrichtung beschrieben worden, mit der während des Umwebens einer Innenschlauchbahn mit einem Rundgewebeschlauch die Innenschlauchbahn in Z-Falten gelegt und im Bereich der Z-FaIten mit Leimtupfern an dem Rundgewebeschlauch befestigt wird. Werden aus einem derartigen Rundgewebeschlauch mit der im Abstand mit Z-Falten versehenen InnenschlauchbahnIn the earlier patent application P 31 11 829.1 a device has been described with which during the wrapping an inner tube sheet with a round fabric tube, the inner tube sheet is placed in Z-folds and in the area of the Z-folds attached to the tubular fabric with glue swabs will. Are made from such a round fabric hose with the inner hose strip provided with Z-folds at a distance

Säcke in der Weise hergestellt, daß sich die Z-Falten im Bereich der öffnungsrander der Säcke befinden, damit sich der Innensack beim Befüllen gleichmäßig an den tragenden gewebten Außensack anlegt, läßt es sich nicht vermeiden, daß beim Befüllen derartiger Säcke Füllgut zwischen den Außen- und Innensack gerät, weil der Innensack im Öffnungsbereich mit dem Außensack nicht vollflächig über seinen Umfang verbunden ist.Sacks made in such a way that the Z-folds in the Area of the opening edges of the bags so that the inner bag is evenly on the load-bearing applied outer sack, it can not be avoided that when filling such sacks between the The outer and inner sack comes into play because the inner sack in the opening area does not cover the entire area with the outer sack Scope is connected.

Störungen können sich beim automatischen Befüllen derartiger Säcke während des Ergreifens und Aufsteckens auf Füllstutzen daraus ergeben, daß die Ränder des Innensackes aneinander haften und beim öffnen des Außensackes sich von den Rändern des Außensackes lösen und nicht vollständig mitgeöffnet werden.Faults can arise when such bags are automatically filled while they are being gripped and placed on the filling spouts result from the fact that the edges of the inner bag adhere to one another and when the outer bag is opened they move away from the edges loosen the outer bag and do not open it completely.

Aufgabe der Erfindung ist es daher, ein Verfahren zu schaffen, nach dem sich Innenschlauchbahnen mit diese umgebenden Rundgewebeschläuchen durchgehend über einen ümfangsbereich verbinden lassen.The object of the invention is therefore to create a method according to which inner tube webs surround one another Have round fabric hoses connected continuously over a circumferential area.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Rundgewebeschlauch im späteren Verbindungsbereich mit einem größeren Abstand der Schußfäden gewebt wird, so daß Gewebedurchbrüche entstehen, und daß auf diesen Ümfangsbereich mit geringer Schußfadendichte Klebstoff aufgetragen wird. Da der den späteren Außensack bildende Rundgewebeschlauch über einen ringförmigen ümfangsbereich mit geringerer Schußfadendichte gewebt worden ist, dringt der in diesem Bereich aufgetragene Klebstoff durch die Gewebedurchbrüche hindurch und verklebt den Innensack in diesem Bereich längs eines umlaufenden Ringes mit dem Außensack. Befindet sich dieAccording to the invention this object is achieved in that the Round fabric hose is woven in the later connecting area with a larger spacing of the weft threads, so that fabric breakthroughs arise, and that adhesive is applied to this circumferential area with a low weft thread density. Since the round fabric tube, which will later form the outer sack, has an annular circumferential area with a lower weft thread density has been woven, the adhesive applied in this area penetrates through the tissue openings and glues the inner sack to the outer sack in this area along a circumferential ring. Is the

durch die Gewebedurchbrüche erzeugte ringförmige Verklebung im Bereich des späteren Öffnungsrandes des Sackes, läßt sich der Innensack mit dem Außensack störungsfrei aufziehen.Ring-shaped gluing produced by the tissue breakthroughs in the area of the later opening edge of the sack can be Open the inner bag with the outer bag without any problems.

Aus der DE-OS 24 59 872 ist es bekannt, einen Sackabschnitt mit niedrigerer Gewirkedichte herzustellen, der beim anschließenden Trennen der Gewirkebahnen zu einzelnen Säcken zur Steuerung der Trenneinrichtung dient.From DE-OS 24 59 872 it is known to produce a sack section with a lower knitted density, which in the subsequent Separating the fabric webs into individual sacks is used to control the separating device.

Aus der DE-GMS 19 59 075 ist es bekannt, Gewebebahnen herzustellen, deren Wegkanten eine erhöhte Anzahl von Kettfaden aufweisen, um die Festigkeit der Kanten zu erhöhen, so daß bei der Herstellung von Säcken im Bereich der Kanten ohne weiteres Nähte angebracht werden können. Durch diese bekannten Sackherstellungsverfahren wird es jedoch nicht nahegelegt, Rundgewebeschläuche bereichsweise durch eine geringere Schußfadendichte mit Gewebedurchbrüchen zu versehen, durch die hindurch durch einen Klebstoffauftrag eine Verklebung mit einer Innenschlauchbahn erfolgen kann.From DE-GMS 19 59 075 it is known to produce fabric webs, the path edges of which have an increased number of warp threads in order to increase the strength of the edges, so that in the production of sacks in the area of the edges can easily be attached seams. Known by this However, it is not suggested to use the bag manufacturing process to replace the circular fabric hoses in some areas with a smaller one To provide weft thread density with fabric breakthroughs through which an adhesive is applied can be done with an inner tube track.

Der Klebstoff kann auf den flachliegenden Gewebeschlauch durch eine Leimauftragswalze aufgetragen werden. Der beispielsweise mit der in der Patentanmeldung P 31 11 829.1 beschriebenen Vorrichtung hergestellte Rundgewebeschlauch mit einer Innenschlauchbahn kann zunächst zu einer Vorratsrolle aufgerollt werden. In einem separaten Arbeitsgang kann dann diese Rolle abgewickelt und die Bahn unter einer Leimauftragswalze hindurchgeführt werden, die formatmäßig auf die durchlaufende Bahn im Bereich des Öffnungsrandes mit geringerer Schußfadendichte einen Leimstreifen aufbringt. Dadurch, daß der Schußbändchenabstand im Bereich des späteren Öffnungsrandes größer ist als im übrigen Schlauchbereich,The adhesive can be applied to the flat fabric tube can be applied by a glue application roller. The example with the device described in the patent application P 31 11 829.1 manufactured round fabric hose with an inner hose strip it can initially be rolled up into a supply roll. In a separate operation this roll can then be unwound and the web passed under a glue application roller, the format-wise on the continuous web in the area of the opening edge applies a strip of glue with a lower weft thread density. Because the weft ribbon spacing is in the area of the later The opening edge is larger than in the rest of the hose area,

wird der in diesem Bereich aufgebrachte Klebstoffstreifen durch das Gewebe hindurch auf den Innensack gedrückt, so daß dieser in dem Bereich, in dem der Klebstoffstreifen aufgebracht ist, vollflächig mit dem Außensack verklebt. Nach dem Aufbringen des ersten Leimstreifens wird die flachliegende Rundgewebeschlauchbahn mit Innenschlauchbahn beispielsweise über Wendestangen um 180° gewendet, so daß auch die gegenüberliegende Seite in Abständen mit Klebstoffstreifen versehen werden kann.becomes the adhesive strip applied in this area pressed through the fabric onto the inner bag, so that it is in the area where the adhesive strip is applied, glued over the entire surface to the outer bag. After applying the first strip of glue, the one lying flat Round fabric hose web with inner hose web, for example, turned by 180 ° over turning bars, so that too the opposite side at intervals with adhesive strips can be provided.

Der Klebstoff kann auch mit einer kreisförmig über den Umfang des Gewebeschlauches geführten Klebstoffauftragsdüse aufgetragen werden. Bei der in der älteren Patentanmeldung P 31 11 829.1 beschriebenen Vorrichtung könnte der Klebstoffauftrag bereits während des Webens des Rundgewebeschlauches dadurch erfolgen, daß die Klebstoffauftragsdüse mit einem Karussell um den Gewebeschlauch herumgeführt wird. Dieses Klebstoffkarussell müßte allerdings während des Umlaufs entsprechend der Webgeschwindigkeit in Abzugsrichtung des Rundgewebeschlauches mitbewegt werden.The adhesive can also be applied with an adhesive application nozzle guided in a circle over the circumference of the fabric hose be applied. In the device described in the earlier patent application P 31 11 829.1, the adhesive application could already take place during the weaving of the tubular fabric in that the adhesive application nozzle with a Carousel is guided around the fabric tube. This adhesive carousel would, however, have to be used accordingly during the cycle the weaving speed are moved in the withdrawal direction of the tubular fabric tube.
