Description

Zwei-Faden-Heftnaht sowie Verfahren und Maschine zu ihrer Herstellung Die Erfindung bezieht sich auf eine aus einem Ober-und einem Unterfaden bestehende Zwei-Faden-Heftnaht. Bei der Herstellung derartiger Nähte ist früher schon versucht worden, das lästige Aufspulen und Spulenwechseln des Unterfadens wegfallen zu lassen und möglichst große Unterfadenspulen zu verwenden.Two-thread stitching seam as well as the method and machine for their manufacture The invention relates to a thread consisting of an upper and a lower thread Two-thread basting seam. Attempts have been made earlier in the production of such seams The annoying winding and changing of the bobbin of the bobbin thread are no longer necessary and use the largest possible bobbins.

Alle bekanntgewordenen Lösungsversuche scheiterten bisher daran, daß bei der Stichbildung die Oberfadellschleife um den gesamten Vorrat des Unterfadens herumgeführt werden muß. Die Größe des Greifers, der diese Herumführung der Oberfadenschleife um den gesamten Unterfadenvorrat (Unterfadenspulen) ausführt, ist begrenzt, und damit ist auch die Größe der Unterfadenspule begrenzt.All attempted solutions that have become known have failed so far because When forming the stitch, the upper thread loop around the entire supply of the lower thread must be shown around. The size of the looper that is guiding this around the needle thread loop around the entire supply of bobbin thread (bobbins) is limited, and this also limits the size of the bobbin.

Die nachstehend beschriebene Erfindung zeigt einen Weg auf, der es ermöglicht, eine Zwei-Faden-Heftnaht zu erzeugen, wobei eine beliebig große Unterfadenspule oder Unterfadenrolle verwendet werden kann. The invention described below shows one way of doing it makes it possible to produce a two-thread basting seam, with a bobbin of any size or bobbin thread roll can be used.

Bei der Heftnaht nach der Erfindung erfolgt das Zusammenhalten von Gewebelagen mit einem Oberfaden und einem Unterfaden und deren Verbindung innerhalb der Stofflagen in ähnlicher Weise wie bei einer Doppelsteppstichnaht. Der Unterschied zwischen der normalen Doppelsteppsticbnaht und dererfindungsgemäß erzeugten Zwei-Faden-Heftnaht besteht darin, daß bei der normalen Doppelsteppstichnaht der Oberfaden mit dem Unterfaden innerhalb der Stofflagen verschlungen wird, bei der Zwei-Faden-Heftnaht nach der Erfindung die Verbindung des Oberfadens mit dem Unterfaden innerhalb der Stofflagen mit Kunststoff, insbesondere thermoplastischem Kunststoff erfolgt. In the sewing seam according to the invention, the holding together takes place Fabric layers with an upper thread and a lower thread and their connection within the layers of fabric in a similar way to a lockstitch seam. The difference between the normal double quilted stitching and the two-thread stitching seam produced according to the invention consists in the fact that with the normal lockstitch seam the upper thread with the bobbin thread is entwined within the layers of fabric, in the case of the two-thread stitching seam after the Invention the connection of the upper thread with the lower thread within the fabric layers takes place with plastic, in particular thermoplastic plastic.

Es ist aus der Strumpfherstellung bekanntgewor den, vollsynthetische Garne zum Zusammennähen der formgerecht gearbeiteten Strümpfe zu verwenden, wobei zur Sicherung des Nahtendes noch ein Stück Leernaht genäht wird, dessen Einzelfäden und gegebenenfalls die Fäden der gesamten Naht durch ein Heißformverfahren miteinander verschweißt werden, um ein Lösen der Naht zu verhindern. Dieses Verfahren ist bei Strumpfwirkmaschinen bekannt, nicht aber bei normalen Nähmaschinen. Es besteht aber bei der geschilderten Verwendung von vollsynthetischen Fäden die Gefahr, daß der Faden sich beim Schweißvorgang auflöst, was nur durch peinlich genaue Temperaturkontrolle verhindert werden könnte. It is known from the manufacture of socks, it is fully synthetic To use yarns to sew the properly worked stockings together, whereby To secure the end of the seam, a piece of empty seam is sewn, its individual threads and optionally the threads of the entire seam together by a hot forming process be welded to prevent the seam from loosening. This procedure is at Known hosiery knitting machines, but not with normal sewing machines. But it does exist with the described use of fully synthetic threads the risk that the The thread dissolves during the welding process, which can only be achieved through meticulous temperature control could be prevented.

Bei der erfindungsgemäßen Zwei-Faden-Heftnaht werden die beiden Fäden in aufeinanderfolgenden Abständen ohne gegenseitige Verschlingung durch Verklebung, Verzahnung od. dgl. mittels thermoplastischer Werkstoffe miteinander verbunden. Der Unterfadenvorrat kann dabei genauso groß sein wie der Oberfadenvorrat. In the two-thread tack seam according to the invention, the two threads at successive intervals without mutual entanglement by gluing, Teeth or the like connected to one another by means of thermoplastic materials. The bobbin thread reserve can be just as large as the upper thread reserve.

Die Zeichnung erläutert den Grundgedanken der Erfindung in verschiedenen Ausführungsvarianten; es zeigt Fig. 1 die Verwendung kugelförmiger Verbindungsmittel für das Verbinden von Oberfaden und Unterfaden, Fig. 2, 3 und 4 die Verwendung von einem zul-aufenden Draht abgeteilter stiftförmiger Verbindungsmittel zur Verbindung von Ober- und Unterfaden, und zwar in verschiedenen Phasen. The drawing explains the basic idea of the Invention in different Design variants; 1 shows the use of spherical connecting means for connecting the upper thread and bobbin thread, Fig. 2, 3 and 4 the use of a pin-shaped connecting means separated from a tapered wire for connection of the upper and lower thread in different phases.

Gemäß Fig. 1 trägt die Platte 12, entsprechend ausgeschnitten, die beiden miteinander durch eine Zwei-Faden-Heftnaht zu verbindenden Gewebelagen 15, 16. According to FIG. 1, the plate 12, cut out accordingly, carries the two fabric layers 15 to be connected to one another by a two-thread stitching seam, 16.

Die Zwei-Faden-Heftnaht wird vom Oberfaden 28 und vom Unterfaden 29 gebildet. Es findet eine punktförmige Verklebung oder ähnliche Vereinigung durch ein thermoplastisches Mittel statt, das in diesem Ausführungsbeispiel eine im Endzustand etwa kugelförmige Verbindung zwischen Oberfaden 28 und Unterfaden 29 schafft. Die Zufuhr erfolgt durch entsprechende Kanäle, wobei das thermoplastische Material in der Gestalt von kleinen Kugeln zugeleitet wird, und zwar von unten und von oben, gegebenenfalls auch nur von einer Seite. Der Vorgang ist so, daß durch den Druckstift 2 und durch den gegenüberliegenden Druckstift 11, die entsprechend gesteuerte gegenläufige Bewegungen ausführen, welche mit der Schrittbewegung des Stoffschiebers abgestimmt sind, jeweils zulaufende thermoplastische Kugeln erfaßt und in das nicht notwendigerweise vorgelochte Gewebe eingedrückt werden, wobei die entsprechend erfaßten Bereiche des Oberfadens 18 und des Unterfadens 29 mit in das Gewebe eingedrückt und durch die thermoplastische Verbindung 3 vereinigt werden. Beim Vereinigungsvorgang wird die thermoplastische Kugel od. dgl. etwa mittels eines Hochfrequenzgenerators (nicht dargestellt) oder sonstiger an sich bekannter Wärmezufuhr in ausreichender Weise erweicht.The two-thread basting seam is made by the upper thread 28 and the lower thread 29 educated. There is a point-like gluing or a similar union a thermoplastic agent instead, which in this exemplary embodiment is one in the final state approximately spherical connection between upper thread 28 and lower thread 29 creates. the It is supplied through appropriate channels, with the thermoplastic material in is fed to the shape of small balls, from below and from above, possibly only from one side. The process is such that through the push pin 2 and by the opposite pressure pin 11, the correspondingly controlled counter-rotating Carry out movements that are coordinated with the step movement of the material pusher are, in each case tapered thermoplastic balls detected and not necessarily in that pre-punched tissue are pressed in, the corresponding areas covered of the upper thread 18 and the lower thread 29 pressed into the fabric and through the thermoplastic compound 3 are combined. In the process of unification, the thermoplastic ball or the like, for example by means of a high-frequency generator (not shown) or other known heat supply in a sufficient manner softened.

Gemäß Fig. 2 bis 4 wird~ das hier kräftigere zwei schichtige Gewebe 32, 33 vorgelocht, und zwar in einem vorangehenden Arbeitsgang. Das Gewebe 32, 33 läuft also beispielsweise von links nach rechts. Sobald das Loch 34 unter der Vorrichtung für die thermoplastische Verbindung von Oberfaden35 und Un-Unterfaden37 angelangt ist, wird mittels geeigneter in dem Kopf 21 untergebrachter Mittel der zulaufende Thermoplastikdraht 20 an seiner Spitze abgetrennt, und zwar so, daß ein stiftartiger Körper 26 abgeschnitten und gemäß Fig. 3 vom sich nach unten bewegenden Kopf21 in das Loch 34 eingedrückt wird, wobei der gegenläufige Finger36 mitwirkt; zwischen den Elementen 26 und 36 werden Ober- und Unterfaden in diesem Bereiche erfaßt und bei schon erwähnter Erwärmung des Thermoplastikstifts 26 miteinander verbunden, wobei sich als endgültige Verbindungsform eine Art Thermoplastikkugel bildet, welche Oberfaden 35 und Unterfaden 37 jeweils im Lochbereiche 34 miteinander vereinigt. According to FIGS. 2 to 4, the two-layer fabric, which is stronger here, becomes 32, 33 pre-punched in a previous operation. The fabric 32, 33 runs from left to right, for example. Once the hole 34 is under the device for the thermoplastic connection of the upper thread35 and the lower thread37 is, by means of suitable means accommodated in the head 21, the tapered one Thermoplastic wire 20 cut off at its tip, in such a way that a pin-like Body 26 cut off and shown in FIG. 3 from the downward moving head 21 in the hole 34 is pressed in with the counter-rotating finger 36 cooperating; between the elements 26 and 36 upper and lower thread are detected in this area and connected to one another when the thermoplastic pin 26 is heated as already mentioned, whereby a kind of thermoplastic ball is formed as the final connection shape, which Upper thread 35 and lower thread 37 are each combined with one another in the hole area 34.

Es mag erwähnt werden, daß als vorteilhaftes Mittel für das Abtrennen der Stifte 26 vom Thermoplastikdraht20 zangenförmige Druckstücke24 dienen können, welche im Inneren des entsprechend konisch gestalteten Kopfs 21 so angeordnet sind, daß eine -asiale Bewegung der zangenförmigen Druckstücke24 in Richtung zum unteren Ende des Kopfes 21 mittels des Kolbens 22 eine Schließung der Zange und damit ein Abtrennen von Stiften 26 bewirkt. Das zangenartige Druckstück 24 dient hierbei außerdem und gleichzeitig dazu, den abgetrennten Stift 26 in das Loch 34 einzudrücken. Vorteilhaft ist es, die zangenförmigen Druckstifte24 so auszubilden, daß ein nach unten geschärfter Stift 26 entsteht, was unter Umständen dieVorlochung 34 entbehrlich macht, insbesondere bei leichteren Geweben. It may be mentioned that as an advantageous means for separating the pins 26 of the thermoplastic wire20 can serve as pliers-shaped pressure pieces24, which are arranged inside the correspondingly conically shaped head 21 so that an -asiale movement of the pincer-shaped pressure pieces 24 in the direction of the lower End of the head 21 by means of the piston 22 a closure of the pliers and thus a Separation of pins 26 causes. The pliers-like pressure piece 24 also serves here and at the same time to push the severed pin 26 into the hole 34. Advantageous is to train the pincer-shaped pressure pins 24 so that a downwardly sharpened Pin 26 is created, which in certain circumstances makes the pre-perforation 34 unnecessary, in particular with lighter fabrics.
