Description

Nahtverbindung Die Erfindung bezieht sich auf eine Nahtverbindung für aufeinanderliegende Werkstoffbahnen, von denen eine aus Fasern thermoplastischen Kunststoffes aufgebaut ist. - Der Ausdruck Nahtverbindung umfaßt hierbei linienförmige Verbindungen zwischen aufeinanderliegenden Werkstoffbahnen. Solche Nahtverbindungen für aufeinanderliegende Werkstoffbahnen sind in verschiedenen Ausführungsformen bekannt, und zwar insbesondere als Nähnähte, welche die aufeinanderliegenden Werkstoffbahnen mittels Fäden miteinander verbinden. Solche Nähnahtverbindungen haben den Vorteil, daß sie mit großer Nähgeschwindigkeit auf dafür eingerichteten Nähmaschinen hergestellt werden können, haben jedoch den Nachteil, daß sie entweder unmittelbar oder nach Zerstörung des Fadens an einer Stelle aufgezogen werden können. Zur Herstellung von Vlies und Filzstoffen ist es bekannt, ein oder zwei Werkstoffbahnen aus Fasern thermoplastischen Kunststoffes mit einer weiteren Werkstoffbahn als Tragschicht flächig im Wege des Nadelns miteinander zu verbinden und die jeweils durch die Tragschicht hindurchgezogenen Faserbüschel in der Tragschicht bzw. dergegenüberliegenden Werkstoffbahn aus Fasern thermoplastischen Kunststoffes durch Verkleben oder Kräuseln mittels Wärmeeinwirkung zu fixieren (DDR-Patentschrift 54 114, DAS 1 102 693, deutsches Gebrauchsmuster 1 917 667). Als wesentlich für eine gute Verbindung zwischen den Werkstoffbahnen muß dabei angesehen werden, daß die Struktur der durch das Nadeln hindurchgezogenen Faserbüschel beim Verkleben oder Kräuseln im wesentlichen erhalten bleibt. Die Probleme um Nahtverbindungen für aufeinanderliegende Werkstoffbahnen, von denen eine aus Fasern thermoplastischen Kunststoffes aufgebaut ist, sind durch die Maßnahmen bei derHerstellung von Vlies-und Filzstoffen bisher nicht beeinflußt worden. Der Erfindung liegt die Aufgabe zugrunde, eire Nahtverbindung für aufeinanderliegende Werkstoffbahnen, von denen eine aus Fasern thermoplastischen Kunststoffes aufgebaut ist, anzugeben, welche nicht aufgezogen werden kann und welche hohe Beanspruchungen aufzunehmen in der Lage ist. Die Erfindung löst dieses Problem für sufeinanderliegende Werkstoffbahnen, von denen die eine aus Fasern thermoplastischen Kunststoffes aufgebaut ist und die andere aus Textil, Leder, Kunststoff oder dergleichen besteht, dadurch, daß Faserbüschel der aus Fasern thermoplastischen Kunststoffes aufgebauten unteren Werkstoffbahn in an sich bekannter Weise im Wege des Nadeins durch die obere werkstoffbahn hindurchgezogen sind und die über die Oberfläche der oberen Werkstoffbahn vorstehealen einzelnen Faserbüschel zu nietkopfartigen Knoten zusammengeschmolzen und dadurch verankert sind. Nach einem we2eren Vorschlag der Erfindung sind die nietkopfartigen Knoten durch Anwendung von Druck und/oder Wärme abgeplattet und vergrößert. Die durch die Erfindung erreichten Vorteile sind darin zu sehen, daß die erfindungsgemäße Nahtverbindung zunächst mit großer Arbeitsgeschwindigkeit einer Nadelmaschine hergestellt werden kann, wobei durch eilen nachgeschalteten Arbeitsgang die beschriebene Verankerung durchgeführt wird. Der nachgeschaltete Arbeitsgang kann dabei in einfacher Weise verwirklicht werden, indem die Werkstoffbahnen im Bereich dc r Nahtverbindung z.8. durch heiße Gase oder Wärmestrahlung beaufschlagt oder auch mit Elementen, wie Glühdrähten, Heizkolben oder dergMchen in Wechselwirkung oder Berührung gebracht werden. Eine entsprechende Vorrichtung kann der Nadelmaschine ohne weiteres nachgeschlatet werden und beeinträchtigt die Arbeitsgeschwindeeit der Nadelmaschine nicht. Die eingangs beschriebenen Nachteile von Nähnähten treten bei dererfindungsgemäßen Nahtverbindung nicht auf. Als überraschend ist bei der erfindungsgemäßen Nahtverbindung anzusehen, daß trotz des Fehlens von Nähfäden eine gegenüber Nähnähten wesentlich verbesserte Verbindung verwirklicht wird, die allen Anforderungen an hohe Beanspruchbarkeit genügt. Im folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstel:'Lenden Zeichnung ausführlicher erläutert. Die einzige Figur zeigt in vergrößerter Darstellung einen Längsschnitt durch eine erfindungsgemäße Nahtverbindung. Die in der Figur dargestellte Nahtverbindung vereinigt zwei aufeinanderliegende Werkstoffbahnen 1,2. Die untere Werkstoffbahn 1 ist aus Fasern 3 thermoplastischen Kunststoffes aufgebest; die obere Werkstoffbahn 2 besteht aus Textil, Leder, Kunststoff oder dergleichen. Aus der unteren Werkstoffbahn 1 sind Faserbüschel 4 im Wege des Nadelns durch die obere Werkstoffbahn 2 hindurchgezogen. Dazu arbeitet man mit Nadeln 6, welche Widerhaken 7 aufweisen. Das ist in der Figur rechts erläuternd dargestellt. Die über die Oberfläche der oberen Werkstoffbahn 2 vorstehenden einzelnen Faserbüschel 4 sind zu nietkopfartigen Knoten 5 zusammengeschmolzen und dadurch verankert. Stets besteht die Möglichkeit, die nietkopfartigen Knoten durch Anwendung von Druck und/oder Wärme noch gleichsam abzuflachen und dadurch im Querschnitt zu vergrößern. Seam connection The invention relates to a seam connection for material webs lying one on top of the other, one of which is made up of fibers of thermoplastic material. - The term seam connection here includes linear connections between material webs lying on top of one another. Such seam connections for material webs lying on top of one another are known in various embodiments, in particular as sewing seams which connect the material webs lying on top of one another by means of threads. Such sewn seam connections have the advantage that they can be made at high sewing speed on sewing machines equipped for this purpose, but have the disadvantage that they can be pulled up at one point either immediately or after the thread has been destroyed. For the production of fleece and felt materials, it is known to connect one or two material webs made of thermoplastic fibers with another material web as a base layer using needles and the tufts of fibers drawn through the base layer in the base layer or the opposite material web made of thermoplastic fibers To fix plastic by gluing or curling by means of heat (GDR patent specification 54 114, DAS 1 102 693, German utility model 1 917 667). It must be regarded as essential for a good connection between the material webs that the structure of the tufts of fibers drawn through the needling is essentially retained during gluing or crimping. The problems with seam connections for material webs lying on top of one another, one of which is made up of thermoplastic fibers, have not been influenced by the measures taken in the manufacture of nonwoven and felt materials. The invention is based on the object of specifying a seam connection for material webs lying on top of one another, one of which is made up of thermoplastic fibers, which cannot be pulled open and which is capable of absorbing high loads. The invention solves this problem for consecutive material webs, one of which is made up of thermoplastic fibers and the other of textile, leather, plastic or the like, in that tufts of fibers of the lower material web made up of thermoplastic fibers in a known manner in the Paths of the needle are pulled through the upper material web and the individual tufts of fibers protruding above the surface of the upper material web are melted together to form rivet-head-like knots and thereby anchored. According to another proposal of the invention, the rivet-head-like nodes are flattened and enlarged by the application of pressure and / or heat. The advantages achieved by the invention are to be seen in the fact that the seam connection according to the invention can initially be produced at a high operating speed of a needle machine, the anchoring described being carried out by a subsequent operation in a hurry. The subsequent work step can be implemented in a simple manner in that the material webs in the area of the seam connection z.8. exposed to hot gases or thermal radiation or brought into interaction or contact with elements such as filaments, heating bulbs or the like. A corresponding device can easily be attached to the needle loom and does not affect the working speed of the needle loom. The disadvantages of sewing seams described at the outset do not occur in the seam connection according to the invention. What is surprising in the seam connection according to the invention is that, despite the lack of sewing threads, a connection that is considerably better than that of sewn seams is achieved which meets all the requirements for high strength. In the following the invention is illustrated by means of only one embodiment: 'Loin drawing explained in more detail. The single figure shows an enlarged view of a longitudinal section through a seam connection according to the invention. The seam connection shown in the figure combines two material webs 1, 2 lying on top of one another. The lower web of material 1 is made of 3 thermoplastic fibers; the upper web of material 2 consists of textile, leather, plastic or the like. Tufts of fibers 4 are drawn from the lower material web 1 through the upper material web 2 by means of needles. For this purpose, needles 6 which have barbs 7 are used. This is illustrated in the figure on the right. The individual fiber tufts 4 protruding above the surface of the upper material web 2 are fused together to form rivet-head-like nodes 5 and thereby anchored. There is always the possibility of flattening the rivet head-like nodes by applying pressure and / or heat and thereby increasing the cross-section.
