In der Textiltechnik liegt oft die Aufgabe vor, Flächengebilde miteinander zu vereinen, besonders dann, wenn Textilbahnen, die kontinuierlich behandelt werden, mit anderen Textilbahnen zu verbinden sind, unabhängig davon, ob diese anderen Textilbahnen nun Hilfsvorrichtungen sind, mit welchen das Behandlungsverfahren durchgeführt wird, oder um Textilbahnen, die dem Verfahren selbst unterworfen werden. Bei solchen Behandlungsverfahren werden die zu bearbeitenden Textilbahnen nicht zur Gänze aus der Behandlungsmaschine herausgezogen, sondern es wird eine neue Bahn an die zu Ende gehende Bahn angeschlossen. Auf diese Weise wird vermieden, daß die Bearbeitungsmaschine, die für solche Textilbehandlungsverfahren außerordentliche Längen aufweisen, leerläuft, welches aufwendige Mehrarbeiten bringt, eine neue Bahn müßte eingezogen werden, die stillstehende Maschine muß gereinigt werden und dgl. mehr. In der nachfolgenden Beschreibung und auch in den Ansprüchen bedeuten Begriffe wie Garnlage, bahn- oder schichtförmiges Material einen faserigen zweidimensionalen Werkstoff, dessen Dicke im Vergleich mit der Breite und insbesondere der Länge nur eine sehr geringen Wert hat. Es handelt sich dabei in der Regel um Textilbahnen in Form von nicht gewebte Stoffen wie Vliese, oder auch von einschichtigen und mehrschichtigen parallelen Fadenscharen beispielweise von Schluß- oder Kettgarnen.The task in textile technology is often to unite fabrics, especially if textile webs that are continuously treated are to be connected to other textile webs, regardless of whether these other textile webs are now auxiliary devices with which the treatment process is carried out, or textile webs that are subjected to the process itself. In such treatment processes, the textile webs to be processed are not completely pulled out of the processing machine, but a new web is connected to the web that is about to end. In this way it is avoided that the processing machine, which has extraordinary lengths for such textile treatment processes, runs idle, which involves expensive additional work, a new web would have to be drawn in, the stationary machine must be cleaned and the like. More. In the following description and also in the claims, terms such as yarn layer, sheet or layered material mean a fibrous two-dimensional material, the thickness of which is only of very low value in comparison with the width and in particular the length. As a rule, these are textile webs in the form of non-woven fabrics such as nonwovens, or also single-layer and multi-layer parallel thread sheets, for example, end or warp yarns.

Textile Bearbeitungsverfahren, die in langgestreckten Anlagen ausgeübt werden, sind Waschen, Sengen, Bleichen, Zurichten, Bedrukken, Ausrüsten und dgl. mehr. Fadenscharen werden meist gefärbt und geschlichtet.Textile processing methods which are carried out in elongated plants are washing, singeing, bleaching, dressing, printing, finishing and the like. Threads are usually dyed and sized.

Verfahren und Maßnahmen zur Behandlung von Fadenscharen anstelle der letztlich gewonnenen Gewebe verbreiten sich immer mehr und es können bei diesem Verfahren alle Veredlungsoperationen ausgeführt werden, sofern dies im Hinblick auf die nachfolgenden Verarbeitungsschritte sinnvoll ist. Solche Verfahren sind beispielsweise beschrieben in der Schweizer Patentschrift 612 557 und in der französischen Patentschrift 12 01 724.Processes and measures for the treatment of thread coulters instead of the ultimately obtained tissue are becoming more and more widespread and all finishing operations can be carried out with this process, provided that this makes sense with regard to the subsequent processing steps. Such methods are described, for example, in Swiss Patent 612 557 and in French Patent 12 01 724.

Es ist sehr aufwendig und schwierig, Garne die solchen Verarbeitungsprozessen unterworfen werden, in eine Verarbeitungsmaschine oder -anlage einzuziehen oder nachzuziehen, um die bereits eingeführten und behandelten Garne zu ersetzen, ist doch die Anzahl der parallelen Garne, die eine solche Anlage durchlaufen, außerordentlich groß, Die Zahl liegt ungefähr zwischen 7 bis 10 000 und die Einzuglängen selbst erreichen beachtliche Werte. Es sind hier Längen von 350 und mehr Meter zu berücksichtigen.It is very time-consuming and difficult to thread or subject yarns that are subjected to such processing processes to a processing machine or plant in order to replace the yarns that have already been introduced and treated, since the number of parallel yarns that pass through such a plant is extremely large , The number is approximately between 7 and 10,000 and the feed lengths themselves reach remarkable values. Lengths of 350 and more meters must be taken into account here.

Wenn Gewebe solchen Bearbeitungsverfahren und Bearbeitungsschritten unterworfen werden, besteht die vorstehend geschilderte Schwierigkeit im geringeren Ausmaß, da in diesem Falle die Anfangsbereiche des neuen Gewebes einfach an die Endbereiche des gerade behandelten Gewebes durch ein oder mehrere Nähte angeschlossen wird, zu welchem Zweck Handnähmaschinen dienen.If fabrics are subjected to such processing methods and processing steps, the above-described difficulty exists to a lesser extent, since in this case the start areas of the new fabric are simply connected to the end areas of the fabric being treated by one or more seams, for which purpose manual sewing machines are used.

In der europäischen Patentschrift 00 63 546 ist nun eine Maßnahme erläutert, mit welcher solche Garnlagen mit einer Textilbahn verbunden werden können. Bei solchen Garnlagen handelt es sich um Textilgebilde, die in Längsrichtung, d.h. in Zugrichtung wie Vliese und parallele Fadenscharen ausfasern. Die nach der europäischen Patentschrift 00 63 546 vorgeschlagene Verbindung besteht nun aus einer Verklebung oder Heißsiegelung, welche mindestens auf derjenigen Seite, die einer Temperaturbeanspruchung beim betriebsmäßigen Einsatz ausgesetzt wird, durch eine wärmeisolierende Schicht abgeschirmt ist. Zu diesem Zweck wird nach dem bekannten Vorschlag, die Lage aus einer Vielzahl von parallelen Garnen in gestrecktem Zustand festgehalten und zwar zwischen einem ersten Streifen aus einem schweißbaren oder heißsiegelfähigen Plastikstoff, der an einem Gewebe befestigt ist, und einem zweiten schweißbaren oder heißsiegelfähigen Streifen, wobei die Ebenen beider Streifen und die Garnlage im wesentlichen parallel zueinander verlaufen. Dann werden die Streifen und die Garnlage zusammengedrückt und die beiden Streifen durch Heißverschweißen oder Versiegeln miteinander verbunden, wobei die Garnlage zwischen den Streifen durch dieses Versiegeln oder Verschweißen sozusagen eingeklemmt wird.In the European patent specification 00 63 546 a measure is now explained with which such layers of yarn can be connected to a textile web. Such layers of yarn are textile structures that extend in the longitudinal direction, i.e. Unravel in the direction of pull like fleeces and parallel thread sheets. The connection proposed according to the European patent specification 00 63 546 now consists of an adhesive or heat seal, which is shielded by a heat-insulating layer at least on the side that is exposed to temperature stress during operational use. For this purpose, according to the known proposal, the layer of a plurality of parallel yarns is held in the stretched state, namely between a first strip of a weldable or heat-sealable plastic that is attached to a fabric and a second weldable or heat-sealable strip, whereby the planes of both strips and the yarn layer run essentially parallel to one another. Then the strips and the yarn layer are pressed together and the two strips are connected to one another by heat welding or sealing, the yarn layer being clamped between the strips by this sealing or welding, so to speak.

Diese vorbekannte Maßnahme hat sich durchaus bewährt und sie wird auch in der Praxis erfolgreich ausgeübt. Der einzige Nachteil dieser Maßnahme liegt darin, daß die schweißbar oder heißsiegelfähigen Stoffe im Vergleich zu normalen einfachen Geweben außerordentlich teuer sind und daß bei der Ausübung dieses Verfahrens solche schweißbare und heißsiegelfähige Stoffe in großen Mengen verwendet werden müssen, was die Ausübung dieser bekannten Maßnahme teuer gestaltet.This previously known measure has proven itself and is also successfully used in practice. The only disadvantage of this measure is that the weldable or heat-sealable materials are extremely expensive compared to normal simple fabrics and that such weldable and heat-sealable materials must be used in large quantities when carrying out this method, which makes the practice of this known measure expensive .

Hier nun setzt die Erfindung ein, die darauf abzielt, eine Vorrichtung der eingangs erwähnten Art so zu gestalten, daß auf den Einsatz und die Verwendung solcher in großen Mengen notwendigen und sehr teuren schweißbaren und heißsiegelfähigen Stoffen verzichtet werden kann. Erfindungsgemäß gelingt dies einmal dadurch, daß zu beiden Seiten der Transportebene der Garnlage und quer zur Transportrichtung derselben Führungen vorgesehen sind, wobei an der einen Führung ein mindestens eine Nähnadel für einen Oberfaden aufweisender Nadelkopf und an der auf der anderen Seite der Transportebene der Garnlage befindlichen Führung ein einen Schiffchen- oder Greifermechanismus für einen Unterfaden aufweisender Schiffchenkopf angeordnet ist und die beiden Köpfe synchron antreibbar und entlang den Führungen synchron verschiebbar sind und die erste Haltevorrichtung zum zeitweiligen Festklemmen des freien Endes des bahnförmigen Materials in Transportrichtung der Garnlage gesehen, hinter jener gedachten Ebene liegt, die die beiden Köpfe mit den Nadeln und den Schiffchen enthält.This is where the invention comes in, which aims to design a device of the type mentioned at the outset in such a way that the use and use of such very necessary and very expensive weldable and heat-sealable substances can be dispensed with. Erfin According to the invention, this is achieved in that the same guides are provided on both sides of the transport plane of the yarn layer and transversely to the transport direction, with at least one sewing needle for an upper thread having a needle head and on the guide located on the other side of the transport plane of the yarn layer a shuttle head or looper mechanism for a bobbin thread is arranged and the two heads can be driven synchronously and moved synchronously along the guides and the first holding device for temporarily clamping the free end of the web-like material in the direction of transport of the yarn layer lies behind that imaginary plane which contains the two heads with the needles and the shuttle.

Ein anderer Lösungsvorschlag mit einfacherem mechanischem Aufbau liegt nun darin, daß auf mindestens einer Seite der Transportebene der Garnlage und quer zur Transportrichtung derselben Führungen vorgesehen sind, wobei an diesen Führungen mindestens eine Näheinrichtung verschiebbar gelagert ist mit einem mindestens eine Nähnadel für einen Oberfaden aufweisenden Nadelkopf und einem einen Schiffchen- oder Greifermechanismus für einen Unterfaden aufweisenden Schiffchenkopf und zwischen der Transportebene der Garnlage und der Näheinrichtung ein Walzenpaar vorgesehen ist, wobei die Achsen der Walzen parallel zu den Führungen verlaufen und die eine Walze oberhalb und die andere Walze unterhalb der rechtwinkelig zur Arbeitsrichtung der Nähnadel stehenden, gedachten Nähebene liegen und voneinander distanziert sind und nahe bzw. in dieser Ebene ein Schieber vorgesehen ist, der auf der der Näheinrichtung abgewandten Seite der Transportebene liegt und gegen diese und über diese hinaus bewegbar ist und das von der Haltevorrichtung geklemmte Ende des Materials an diesem Schieber vorbeigeführt ist.Another proposed solution with a simpler mechanical structure is that guides are provided on at least one side of the transport plane of the yarn layer and transversely to the transport direction, at least one sewing device being slidably mounted on these guides with a needle head having at least one sewing needle for an upper thread and a shuttle or hook mechanism for a bobbin head and a pair of rollers is provided between the transport plane of the yarn layer and the sewing device, the axes of the rollers running parallel to the guides and one roller above and the other roller below that perpendicular to the working direction of the Sewing needle, imaginary sewing plane are located and spaced from each other and near or in this plane a slide is provided, which lies on the side of the transport plane facing away from the sewing device and against it and over it us movable and the end of the material clamped by the holding device is guided past this slide.

Es ist an dieser Stelle zu vermerken, worauf schon einleitend hingewiesen wurde, daß es bekannt ist, Gewebebahnen miteinander durch Nähte zu verbinden. In einem solchen Fall wird der Anfangsbereich des neuen Gewebes einfach an den Endbereich des gerade behandelten Gewebes angenäht. Dies mit Handnähnmaschinen. Wenn aber Textilgebilde vorliegen, die in Längsrichtung wie Vliese oder parallele Fadenscharen ausfasern, so wurde eine solche Lösung (Zusammennähen) als nicht brauchbar betrachtet. Entgegen dieser Ansicht ist es jedoch nunmehr möglich, Garnlagen mit einem bahn- oder schichtförmigen Material ausschließlich durch Nähte wärme- und zugfest sowie biegsam zu verbinden, so daß darauf verzichtet werden kann, die teuren und aufwendigen heißsiegelfähigen und schweißbaren Stoffe einzusetzen. Unter einem Nadelkopf im Sinne dieser Beschreibung wird eine mechanische Einrichtung verstanden mit mindestens einer hin und hergehenden Nähnadel, die einen Oberfaden führt, wie dies bei Nähmaschinen bekannt ist. Unter Schiffchenkopf wird eine mechanische Einrichtung im Sinne dieser Erfindung verstanden, die Schiffchen oder Greifer aufweist, die einen Unterfaden führen und die mit der Nadel des Nadelkopfes zusammenwirken, um eine aus mindestens zwei Fäden gebildete Naht zu schaffen.It should be noted at this point, as has already been mentioned in the introduction, that it is known to connect fabric webs to one another by means of seams. In such a case, the beginning area of the new tissue is simply sewn onto the end area of the tissue just treated. This with hand sewing machines. However, if there are textile structures that fiber in the longitudinal direction, such as fleeces or parallel thread sheets, such a solution (sewing together) was considered to be unusable. Contrary to this view, however, it is now possible to connect layers of yarn with a web or layered material exclusively by seams in a heat and tensile and flexible manner, so that it is not necessary to use the expensive and complex heat-sealable and weldable materials. A needle head in the sense of this description means a mechanical device with at least one reciprocating sewing needle that guides an upper thread, as is known in sewing machines. A boat head is understood to mean a mechanical device in the sense of this invention, which has boats or grippers which guide a lower thread and which cooperate with the needle of the needle head in order to create a seam formed from at least two threads.

Die Vorrichtung nach Fig. 1 stellt ein erstes Ausführungsbeispiel der Erfindung dar und ist an der Einlaufseite einer Garnbehandlungsanlage ortsfest angeordnet, von welcher hier jedoch nur der sogenannte Kompensator 20 dargestellt ist. In einem geeigneten, hier nicht im Detail ausgeführten Maschinengestell 1 ist die horizontal verlaufende Transportebene E durch eine die Vorrichtung quer durchsetzende Garnlage 2 im Sinne der vorstehenden Darlegungen dargestellt, die etwa in halber Höhe der Vorrichtung liegt. Die Transportrichtung, in welcher die Garrilage 2 die Anlage und Vorrichtung durchläuft, ist durch einen Pfeil 3 gekennzeichnet. Oberhalb und unterhalb dieser Transportebene sind feststehend im Maschinengestell 1 schienenartige Führungen 4 und 5 vorgesehen. Entlang der oberen Führung 4 und mit dieser verbunden ist ein Nadelkopf 6 verschiebbar gelagert, der hier zwei Nadeln 7 und 8 trägt. Diese beiden Nadeln 7 und 8 sind, wie Fig. 1 zeigt, in Transportrichtung (Pfeil 3) gegeneinander versetzt. Beim betriebsmäßigen Einsatz bewegt sich dieser Nadelkopf senkrecht zur Zeichenebene in Fig. 1. Entlang der Führung 5 und mit dieser verbunden ist ein Maschinenkopf 9 - nachstehend Schiffchenkopf - verschiebbar gelagert, in welchem Schiffchen- oder Greifermechanismen angeordnet sind. Die Nadeln 7 und 8 führen den Oberfaden, die Schiffchen oder Greifer einen Unterfaden. Unter Nadelkopf im Sinne der gegenständlichen Erfindung wird eine Mechanik verstanden wie sie von Nähmaschinen her bekannt ist. Die Nadeln sind in ihrer Achsrichtung bewegbar und tragen nahe ihrem spitzen Ende eine Öse, durch welche der sogenannte Oberfaden geschlungen ist. Unter Schiffchenkopf im Sinne dieser Erfindung wird eine mechanische Einrichtung verstanden, in welcher Schiffchen oder Greifer gelagert sind, die einen Unterfaden führen und die mit der hin- und hergehenden Nadel zur Bildung eines Stiches in herkömmlicher Weise zusammenwirken. Im vorliegenden Ausführungsbeispiel sind die beiden Maschinenköpfe 6 und 9 über ein U-förmiges Joch 10 (Fig. 2) miteinander verbunden, dessen Tiefe größer ist als die Breite der zu behandelnden Garnlage 2. Die Ebene des Joches 10 steht dabei rechtwinkelig zur Zeichenebene in Fig. 1 bzw. liegt parallel zur Zeichenebene in Fig. 2. Ein Antriebsmotor 11 für die Nähnadeln 7 und 8 und den Schiffchenkopf ist zweckmäßigerweise direkt an diesem Joch 10 angeflanscht und die Antriebselemente für den synchronen Antrieb von Nadel und Schiffchen verlaufen zweckmäßigerweise in den als Hohlkästen ausgebildeten Schenkeln dieses Joches 10. Der die beiden Schenkel des Joches 10 verbindende Abschnitt ist, wie Fig. 2 zeigt, gegenüber dem Boden 12 über eine Strebe 13 mit einer Laufrolle 14 abgestützt, die zweckmäßigerweise entlang einer Führungsbahn geführt ist. Die Arbeitsrichtung des Joches 10 ist durch einen Pfeil 15 in Fig. 2 angedeutet. Der Schiffchenkopf 9 ist ferner von einer ortsfest gelagerten jedoch drehbaren Gewindespindel 16 durchsetzt, die über einen ortsfesten Motor 17 antreibbar ist. Durch die sich drehende Spindel 16 wird das Joch 10 und mit ihm der Nadelkopf 6 und der Schiffchenkopf 9 synchron und rechtwinkelig zur Zeichenebene nach Fig. 1 verfahren.The device according to FIG. 1 represents a first exemplary embodiment of the invention and is arranged in a stationary manner on the inlet side of a yarn treatment plant, of which only the so-called compensator 20 is shown here. In a suitable machine frame 1, which is not detailed here, the horizontally running transport plane E is represented by a yarn layer 2 passing through the device in the sense of the above explanations, which lies approximately halfway up the device. The direction of transport in which the garrilage 2 passes through the system and device is indicated by an arrow 3. Above and below this transport plane, rail-like guides 4 and 5 are provided in the machine frame 1. Along the upper guide 4 and connected to it, a needle head 6 is slidably mounted, which carries two needles 7 and 8 here. These two needles 7 and 8 are, as shown in FIG. 1, offset from one another in the transport direction (arrow 3). In operational use, this needle head moves perpendicular to the plane of the drawing in Fig. 1. Along the guide 5 and connected to it, a machine head 9 - hereinafter the shuttle head - is slidably mounted, in which shuttle or gripper mechanisms are arranged. The needles 7 and 8 guide the upper thread, the shuttle or looper a lower thread. In the sense of the present invention, a needle head is understood to mean a mechanism such as that used in sewing machines is known. The needles can be moved in their axial direction and have an eyelet near their pointed end through which the so-called upper thread is looped. For the purposes of this invention, the shuttle head is understood to mean a mechanical device in which shuttle or hook are mounted, which guide a lower thread and which cooperate with the reciprocating needle in a conventional manner to form a stitch. In the present exemplary embodiment, the two machine heads 6 and 9 are connected to one another via a U-shaped yoke 10 (FIG. 2), the depth of which is greater than the width of the yarn layer 2 to be treated. The plane of the yoke 10 is at right angles to the plane of the drawing in FIG 1 or is parallel to the drawing plane in Fig. 2. A drive motor 11 for the sewing needles 7 and 8 and the shuttle head is expediently flanged directly to this yoke 10 and the drive elements for the synchronous drive of needle and shuttle run expediently in the hollow boxes trained legs of this yoke 10. The section connecting the two legs of the yoke 10 is, as shown in FIG. 2, supported against the floor 12 by a strut 13 with a roller 14 which is expediently guided along a guide track. The working direction of the yoke 10 is indicated by an arrow 15 in FIG. 2. The shuttle head 9 is also penetrated by a stationary but rotatable threaded spindle 16 which can be driven by a stationary motor 17. The rotating spindle 16 moves the yoke 10 and with it the needle head 6 and the shuttle head 9 synchronously and at right angles to the drawing plane according to FIG. 1.

Unterhalb der Transportebene E und in Transportrichtung (Pfeil 3) gesehen hinter der Bewegungsebene der beiden Köpfe 6 und 9 ist eine erste Haltevorrichtung 18 angeordnet, die aus zwei gegeneinander verstellbaren leistenförmigen Klemmbacken 21 und 22 gebildet ist, wobei aus Gründen der Ubersichtlichkeit, die Verstelleinrichtung für diese beiden Backen 21 und 22 hier in Fig. 1 nicht gezeigt ist. Als Verstelleinrichtung können hier zweckmäßigerweise hydraulische oder pneumatisch betätigbare Kolben-Zylinder-Einheiten eingesetzt werden. Gegenüber dem Schiffchenkopf 9 ist diese Haltevorrichtung 18 so angeordnet, daß ihre Auflageebene für das bahn-oder schichtförmige Material 19 auf etwa dem gleichen Niveau liegt wie die Auflageebene 23 des Schiffchenkopfes 9, vor welcher, ebenfalls in Transportrichtung (Pfeil 3) gesehen, und unterhalb der Transportebene E eine frei drehbare Umlenkwalze 24 im Maschinengestell 1 gelagert ist.Below the transport plane E and seen in the transport direction (arrow 3) behind the plane of movement of the two heads 6 and 9, a first holding device 18 is arranged, which is formed from two mutually adjustable strip-shaped clamping jaws 21 and 22, the adjustment device for these two jaws 21 and 22 are not shown here in FIG. 1. Hydraulically or pneumatically actuable piston-cylinder units can expediently be used as the adjusting device. Compared to the shuttle head 9, this holding device 18 is arranged in such a way that its support plane for the sheet-like or layered material 19 is at approximately the same level as the support plane 23 of the shuttle head 9, in front of which, also in the direction of transport (arrow 3), and below the transport plane E a freely rotatable deflection roller 24 is mounted in the machine frame 1.

Vor dem Maschinengestell 2 der Vorrichtung und ebenfalls unterhalb der Transportbahn E ist ein Wagen 25 rechtwinkelig zur Zeichenebene nach Fig. 1 verfahrbar gelagert, der eine Vorratsrolle 26 trägt, auf welcher das bahn- oder schichtförmige Material 19 aufgewickelt ist.In front of the machine frame 2 of the device and also below the transport path E, a carriage 25 is mounted at right angles to the plane of the drawing according to FIG. 1 and carries a supply roll 26 on which the web or layered material 19 is wound.

Oberhalb der Transportebene E und somit oberhalb der Garnlage 2 ist nun eine zweite Haltevorrichtung vorgesehen, die aus zwei Klemmleistenpaaren 27 und 28 besteht. Diese beiden Paare 27 und 28 sind so angeordnet, daß zwischen ihnen die gedachte Verschiebeebene des Nadelkopfes 6 liegt, mit anderen Worten, die beiden Klemmleistenpaare 27 und 28 liegen auf je unterschiedlichen Seiten des Nadelkopfes 6 und erstrecken sich ebenfalls rechtwinkelig zur Zeichenebene nach Fig. 1. Auch für diese Klemmleistenpaare sind Verstelleinrichtungen 29 und 30 vorgesehen, die jedoch aus Gründen der Ubersichtlichkeit in Fig. 1 nicht dargestellt sind.Above the transport plane E and thus above the yarn layer 2, a second holding device is now provided, which consists of two pairs of terminal strips 27 and 28. These two pairs 27 and 28 are arranged so that the imaginary displacement plane of the needle head 6 lies between them, in other words, the two pairs of terminal strips 27 and 28 lie on different sides of the needle head 6 and also extend at right angles to the plane of the drawing according to FIG. 1 Adjustment devices 29 and 30 are also provided for these pairs of terminal strips, which, however, are not shown in FIG. 1 for reasons of clarity.

Je eine Leiste der beiden Klemmleistenpaare 27 und 28 ist endseitig mit einem Querholm 31 verbunden und diese Teile bilden zusammen einen Rahmen 44, der entlang von vertikalen Führungen 32 mittels einer Verstelleinrichtung 33 gehoben und gesenkt werden kann. Diese vertikalen Führungen 32 sind Teile eines Schlittens 34, der seinerseits horizontal entlang einer bezüglich des Maschinengestelles 1 ortsfesten Führung 35 horizontal verschiebbar ist. Auch dazu dient als Verstelleinrichtung 36 eine Kolben-Zylinder-Einheit.One strip of each of the two pairs of clamping strips 27 and 28 is connected at the end to a cross member 31 and these parts together form a frame 44 which can be raised and lowered along vertical guides 32 by means of an adjusting device 33. These vertical guides 32 are parts of a carriage 34 which, in turn, is horizontally displaceable horizontally along a guide 35 which is stationary with respect to the machine frame 1. A piston-cylinder unit also serves as the adjusting device 36.

Auf der Seite des Maschinengestelles, die der Garnbehandlungsanlage zugewandt ist, ist noch eine Klemmeinrichtung 37 vorgesehen, durch deren beide Klemmbacken die Transportebene E bzw. die Garnlage 2 verläuft. Eine Kolben-Zylinder-Einheit 38 dient auch hier zur Betätigung dieser Klemmeinrichtung. Ihr gegenüber, auf der Eingangsseite der Vorrichtung bzw. des Maschinengestelles 1, ist noch eine Schneidleiste 39 vorgesehen, deren Betätigungseinrichtung hier jedoch nicht dargestellt ist. Soweit zum konstruktiven Aufbau der Vorrichtung.On the side of the machine frame that faces the yarn treatment system, a clamping device 37 is also provided, through the two clamping jaws of which the transport plane E or the yarn layer 2 runs. A piston-cylinder unit 38 also serves to actuate this clamping device. Opposite it, on the input side of the device or machine frame 1, there is also a cutting bar 39, the actuating device of which is not shown here. So much for the construction of the device.

Im folgenden wird nun die Arbeitsweise dieser Vorrichtung beschreiben: Eine parallele Faden-oder Garnschar, hier als Garnlage 2 bezeichnet, läuft von nicht dargestellten Zettelbäumen ab und von links her (Fig. 1) in die Vorrichtung ein, durch diese hindurch und anschließend über eine erste Umlenkwalze 40 in die eigentliche Garnbehandlungsanlage mit dem vorgeschalteten Kompensator 20, wo sie den eigentlichen Bearbeitungsvorgängen nacheinander unterworfen wird. Auf dem aufgezeigten Weg geht die Garnlage 2 durch die vorstehend erläuterten Teile hindurch, deren Zusammenwirken nachstehend nun erläutert wird. Vorausgeschickt wird dabei, daß die Fig. 1 diese Teile in ihrer jeweiligen Stellung zeigt, die sie während des normalen Arbeitsablaufes einnehmen, d.h. die Schneidleiste 39 und die Klemmvorrichtung 37 sind geöffnet, die Klemmleistenpaare 27 und 28 sind angehoben, ebenso die Nadeln 7 und 8 des Nadelkopfes 6 und der Antriebsmotor 17 steht still. Auf der Vorratsrolle 26 ist eine Stoffbahn aufgewickelt und ein Stück dieser Stoffbahn 19 ist abgezogen, über die Umlenkrolle 24 und den Schiffchenkopf 9 geführt und das freie Ende ist in der ersten Haltevorrichtung 18 eingespannt. Diese Stoffbahn 19 ist gespannt, da sie von der Vorratsrolle 26 gegen die Wirkung einer dort angeordneten, jedoch nicht dargestellten Abzugsbremse abgezogen ist. Ferner ist von den beiden Klemmleistenpaaren 27 und 28 ein Stoffstreifen 41 festgehalten und gespannt, der wie aus Fig. 1 ersichtlich, oberhalb der Garnlage 2 bzw. der Transportebene E liegt. Diese Anordnung betrifft und zeigt die Vorrichtung dann, wenn die Garnlage 2 die Behandlungsanlage ordnungsgemäß durchläuft, und auf den nicht dargestellten Zettelbäumen noch ein hinreichender Garnvorrat vorhanden ist.The mode of operation of this device is now described below: A parallel group of threads or yarn, here referred to as yarn layer 2, runs from not shown paper trees and runs from the left (FIG. 1) into the device, through it and then over one first deflection roller 40 into the actual yarn treatment plant with the upstream compensator 20, where it is subjected to the actual processing operations one after the other. On the path shown, the yarn layer 2 passes through the parts explained above, the interaction of which will now be explained below. It is anticipated that Fig. 1 shows these parts in their respective position, which they assume during normal work flow, ie the cutting bar 39 and the clamping device 37 are open, the pairs of clamping bars 27 and 28 are raised, as are the needles 7 and 8 the needle head 6 and the drive motor 17 is stationary. A fabric web is wound on the supply roll 26 and a piece of this fabric web 19 is pulled off, guided over the deflection roller 24 and the shuttle head 9 and the free end is clamped in the first holding device 18. This web of fabric 19 is taut, since it does not come from the supply roll 26 against the action of one arranged there the trigger brake shown is removed. Furthermore, a fabric strip 41 is held and tensioned by the two pairs of terminal strips 27 and 28, which, as can be seen in FIG. 1, lies above the yarn layer 2 or the transport plane E. This arrangement concerns and shows the device when the yarn layer 2 passes through the treatment plant properly and there is still a sufficient supply of yarn on the slip trees (not shown).

Geht nun aber die Garnlage 2 zu Ende, so muß nun die notwendige Verbindung mit dem Material 19 hergestellt werden und es wird nun vorerst der weitere Lauf der Garnlage 2 durch die erfindungsgemäße Vorrichtung gestoppt, indem die Klemmvorrichtung 37 betätigt wird, die sich schließt und die nun die Garnlage 2 festhält, indem diese zwischen den beiden Backen eingeklemmt wird. Die Garnlage 2, in Fig. 1 links der Klemmeinrichtung 37 bleibt jedoch gespannt, bedingt durch den Abwickelwiderstand von den Zettelbäumen oder eventuell durch eigene hier nicht vorgesehene Abzugsbremsen. Der Behandlungsvorgang jedoch in der Behandlungsanlage läuft ungehindert weiter, denn im Kompensator 20 ist dafür eine hinreichende Menge der zu behandelnden Garnlage bevorratet.But now the yarn layer 2 is coming to an end, the necessary connection must now be made with the material 19 and the further running of the yarn layer 2 is now stopped by the device according to the invention by actuating the clamping device 37, which closes and the now hold the thread ply 2 by pinching it between the two jaws. The yarn layer 2, in FIG. 1 on the left of the clamping device 37, remains tensioned, however, due to the unwinding resistance from the slip trees or possibly due to own trigger brakes not provided here. However, the treatment process in the treatment plant continues unimpeded, because a sufficient amount of the yarn layer to be treated is stored in the compensator 20.

Nun werden die Kolben-Zylinder-Einheiten 33 beaufschlagt und dadurch werden die Klemmleistenpaare 27 und 28 und der von ihnen gespannt gehaltene Stoffstreifen 41 soweit abgesenkt, daß die Stoffbahn 19, die Garnlage 2 und der Stoffstreifen 41 auf der Auflageebene 23 des Schiffchenkopfes 9 aufliegen. Dabei wird die Garnlage 2 zwischen den zusammengefahrenen Klemmleisten bzw. Druckleisten eingespannt. Nun werden die Antriebsmotoren 11 für die Näheinrichtung und der Antriebsmotor 17 für die Verschiebung derselben eingeschaltet und die drei erwähnten Teile 2, 19 und 41 werden nun zusammengenäht, und zwar bei einem Bewegungsablauf der Näheinrichtung durch zwei Nähte, die aufgrund der gewählten Anordnung der Nadeln 7 und 8 gegeneinander versetzt liegen. Hat die Näheinrichtung, bestehend aus den Köpfen 6 und 9 und ausgehend von der in Fig. 2 gezeigten Ausgangslage ihre linke Endstellung (Fig. 3) erreicht, so wird der Antriebsmotor 11 für die Näheinrichtung bei hochgezogenen Nadeln kurzzeitig stillgesetzt und mittels der Verstelleinrichtung 36 (Fig. 3) die geschlossenen und gegeneinander gedrückten Klemmleistenpaare und Druckleisten 18, 27, 28, 42 etwas nach rechts gezogen und dann werden die Antriebsmotoren 11 und 17 neuerlich zugeschaltet, worauf das Joch 10 in seine aus Fig. 3 ersichtliche Ausgangsstellung zurückläuft, wobei gleichzeitig wiederum zwei Nähte gefertigt werden.Now the piston-cylinder units 33 are acted upon and the pairs of terminal strips 27 and 28 and the fabric strip 41 held by them are lowered so far that the fabric web 19, the yarn layer 2 and the fabric strip 41 lie on the support plane 23 of the shuttle head 9. The yarn layer 2 is clamped between the collapsed terminal strips or pressure strips. Now the drive motors 11 for the sewing device and the drive motor 17 for shifting the same are switched on and the three parts 2, 19 and 41 mentioned are now sewn together, namely during a movement sequence of the sewing device by means of two seams which, due to the selected arrangement of the needles 7 and 8 are offset from each other. When the sewing device, consisting of the heads 6 and 9 and starting from the starting position shown in FIG. 2, has reached its left end position (FIG. 3), the drive motor 11 for the sewing device is briefly stopped when the needles are pulled up and by means of the adjusting device 36 ( Fig. 3) the closed and pressed against each other terminal block pairs and pressure strips 18, 27, 28, 42 a little to the right and then the drive motors 11 and 17 are switched on again, whereupon the yoke 10 returns to its initial position shown in FIG. 3, at the same time again two seams are made.

Sobald das Joch 10 seine Ausgangslage erreicht hat (Fig. 3) werden die Motoren 11 und 17 abgeschaltet. Die Nadeln 7 und 8 hochgefahren, die Klemmeinrichtungen 18, 27 und 28 geöffnet und auseinandergefahren und die Garnlage 2 selbst durch Betätigung der Schneidleiste 39 durchtrennt und dann die Klemmvorrichtung 37 geöffnet. Die von der Garnbehandlungsanlage her wirkende Einzugskraft zieht nun über die in dieser Behandlungsanlage noch laufende Garnlage 2 den Stoff 19 von der Vorratsrolle 26 ab. Dieser Stoff 19 hat bei dem hier nicht näher beschriebenen Garnbehandlungsverfahren nur die Aufgabe, als Produktionshilfsmittel zu dienen und er ist wiederholt verwendbar und verwertbar. Dazu kann ein normaler einfacher Stoff verwendet werden, der aus Kett- und Schußfäden gebildet ist, es sind aber auch andere Materialien denkbar, beispielsweise Schichtmaterialien, wie Kunststoff-Folien od.dgl.As soon as the yoke 10 has reached its starting position (FIG. 3), the motors 11 and 17 are switched off. The needles 7 and 8 raised, the clamping devices 18, 27 and 28 opened and moved apart and the yarn layer 2 itself cut by actuating the cutting bar 39 and then the clamping device 37 opened. The pulling force acting from the yarn treatment plant now pulls the substance 19 off the supply roll 26 via the yarn layer 2 still running in this treatment plant. In the yarn treatment process, which is not described in more detail here, this substance 19 has only the task of serving as a production aid and it can be used and used repeatedly. For this purpose, a normal simple fabric can be used, which is formed from warp and weft threads, but other materials are also conceivable, for example layer materials, such as plastic films or the like.

Eine Verbindung zwischen dem Material 19, dem Stoffstreifen 41 und der Garnlage 2 zeigt Fig. 5 in Schrägsicht. Die hier vorhandenen vier Nähte sind gegeneinander versetzt. Wie Zugversuche mit derart hergestellten Verbindungen zeigen, sind diese außerordentlich belastungsfähig. Diese Verbindung, wie vorstehend beschrieben und in Fig. 5 veranschaulicht, besteht aus den erwähnten vier gegeneinander versetzten Nähten und den beiden Stoffen 19 und 41, zwischen welchen die Garnlage 2 gehalten ist. Es ist nun möglich, die Näheinrichtung mit den Köpfen 6 und 9 wiederholt bei der Herstellung einer Verbindung in Betrieb zu setzen, so daß nicht nur vier sondern beispielsweise acht Nähte gefertigt werden. Es ist auch möglich, im Nadelkopf mehr als zwei Nadeln anzuordnen, so daß bei einem Lauf der Näheinrichtung gleichzeitig mehr als zwei Nähte hergestellt werden können.5 shows a connection between the material 19, the fabric strip 41 and the yarn layer 2 in an oblique view. The four seams here are offset against each other. As tensile tests with connections made in this way show, these are extremely resilient. This connection, as described above and illustrated in Fig. 5, consists of the four staggered seams mentioned and the two fabrics 19 and 41, between which the yarn layer 2 is held. It is now possible to repeatedly put the sewing device with the heads 6 and 9 into operation during the establishment of a connection, so that not only four but, for example, eight seams are produced. It is also possible to arrange more than two needles in the needle head, so that more than two seams can be produced at the same time in one run of the sewing device.

Der obere Stoffstreifen 41 übernimmt in dieser Verbindung zwei Aufgaben, einmal dient er als eigentliches Verbindungselement und ferner dient er dazu, dem Niederhalter, der jeder Nadel zugeordnet ist, ein ungehindertes Gleiten über das zu vernähende Material zu ermöglichen. Falls an die Zugfestigkeit der Verbindung keine allzugroßen Anforderungen gestellt werden, ist es durchaus denkbar, bei der Herstellung dieser Verbindung den oberen Streifen 41 beispielsweise sozusagen wegzulassen. Damit in diesem Falle ohne Schwierigkeiten genäht werden kann, ist vorgesehen, daß der mit der Nähnadel des Nadelkopfes 6 zusammenwirkende Niederhalter (siehe Fig. 6) als frei drehbar gelagerte Scheibe 45 ausgebildet ist, deren Drehachse 46 parallel zur Transportrichtung (Pfeil 3) der Garnlage 2 liegt.The upper fabric strip 41 takes on two tasks in this connection, first it serves as the actual connecting element and it also serves to enable the hold-down device, which is assigned to each needle, to slide freely over the material to be sewn. If the demands on the tensile strength of the connection are not too great, it is entirely conceivable to omit the upper strip 41, for example, when making this connection. So that sewing can be carried out without difficulty in this case, it is provided that the holding-down device cooperating with the sewing needle of the needle head 6 (see FIG. 6) is designed as a freely rotatable disc 45, the axis of rotation 46 of which is parallel to the direction of transport (arrow 3) of the thread layer 2 lies.

Im gezeigten Ausführungsbeispiel sind Nadelkopf 6 und Schiffchenkopf 9 über ein Joch 10 mechanisch miteinander verbunden. Während des Nähvorganges wandert dieses Joch 10 seitlich aus. Dafür muß ein entsprechender Platz in der Maschinenhalle vorgesehen sein. Es ist auch möglich, Nadelkopf 6 und Schiffchenkopf 9 als selbständige und voneinander mechanisch getrennte Einheiten zu verwenden, also auf das sie verbindende Joch 10 zu verzichten. Aufgrund der heute zur Verfügung stehenden modernen elektronischen Steuer- und Regeleinrichtungen kann auch unabhängig von einer solchen mechanischen Verbindung über ein Joch 10 ein exakter synchroner Lauf dieser räumlich voneinander getrennten Bauelemente erreicht werden.In the exemplary embodiment shown, the needle head 6 and the shuttle head 9 are mechanically connected to one another via a yoke 10. During the sewing process, this yoke 10 migrates sideways. A corresponding place in the machine hall must be provided for this. It is also possible to use the needle head 6 and the shuttle head 9 as independent and mechanically separate units, that is to say without the yoke 10 connecting them. Due to the modern electronic control and regulation devices available today, an exact synchronous running of these spatially separated components can also be achieved independently of such a mechanical connection via a yoke 10.

Die Fig. 7 bis 10 veranschaulichen nun ein zweites Ausführungsbeispiel der Erfindung, das einen gegenüber dem erstbeschriebenen Ausführungsbeispiel vereinfachten mechanischen Aufbau hat. Zur Bezeichnung gleicher Teile wurden bei beiden Ausführungsbeispielen gleiche Hinweisziffern verwendet. Die Vorrichtung nach Fig. 7 ist ebenfalls an der Einlaufseite einer Garnbehandlungsanlage ortsfest angeordnet, von welcher auch hier jedoch nur der sogenannte Kompensator 20 dargestellt ist. In einem geeigneten, hier nicht im Detail ausgeführten Maschinengestell 1 ist die winkelig verlaufende Transportebene E durch eine die Vorrichtung durchsetzende Garnlage 2 im Sinne der vorstehenden Darlegungen dargestellt. Die Transportrichtung, in welcher die Garnlage 2 die Anlage und Vorrichtung durchläuft, ist durch einen Pfeil 3 gekennzeichnet.7 to 10 now illustrate a second exemplary embodiment of the invention, which has a simplified mechanical structure compared to the first described exemplary embodiment. The same reference numerals have been used to designate the same parts in both exemplary embodiments. The device according to FIG. 7 is also arranged in a stationary manner on the inlet side of a yarn treatment plant, of which only the so-called compensator 20 is shown here, however. In a suitable machine frame 1, which is not detailed here, the angularly extending transport plane E is represented by a yarn layer 2 passing through the device in the sense of the above explanations. The direction of transport in which the yarn layer 2 passes through the system and device is indicated by an arrow 3.

Die Garnlage 2 läuft in etwa halber Höhe des Maschinengestelles 1 auf diese zu und wird durch eine frei drehbare Umlenkwalze 5 vertikal nach unten umgelenkt. Im Bodenbereich des Maschinengestelles 1 sind weitere Umlenkwalzen 51 und 52 vorgesehen, über welche die Garnlage 2 dem Kompensator 20 zugeleitet wird. Es sei bereits an dieser Stelle vermerkt, daß die Umlenkwalze 51 im Bodenbereich des Maschinengestelles 1 nicht orstfest gelagert ist, vielmehr ist diese Umlenkwalze vertikal verstellbar. Der Pfeil in Fig. 1 oberhalb der Umlenkwalze 51 deutet diese vertikale Verschiebemöglichkeit an.The yarn layer 2 runs towards the machine frame 1 at about half the height thereof and is deflected vertically downwards by a freely rotatable deflection roller 5. In the bottom area of the machine frame 1, further deflection rollers 51 and 52 are provided, via which the yarn layer 2 is fed to the compensator 20. It should be noted at this point that the deflecting roller 51 is not fixed in place in the bottom region of the machine frame 1, but rather this deflecting roller is vertically adjustable. The arrow in Fig. 1 above the deflecting roller 51 indicates this vertical displacement possibility.

Im Bereich zwischen den übereinander liegenden Umlenkwalzen 50 und 51 im Bereich der Eingangsseite des Maschinengestelles 1 verläuft die Garnlage 2 bzw. die Transportebene E vertikal. In diesem vertikal verlaufenden Abschnitt der Transportebene E und seitlich derselben sind feststehend im Maschinengestell 1 schienenartige Führungen 4, 5 übereinander liegend vorgesehen. An diesen schienenartigen Führungen 4 und 5 ist ein Support 53 verschiebbar gelagert und zwar rechtwinkelig zur Zeichenebene, wobei zu dieser Verschiebung eine zu den schienenartigen Führungen 4 und 5 parallel liegende, ortsfeste, jedoch drehbar gelagerte Gewindespindel 16 dient, die von einem hier vereinfacht dargestellten Motor 17 in beiden Drehrichtungen antreibbar ist, so daß dieser Support 53 sowohl in die Zeichenebene hinein wie auch aus dieser Zeichenebene heraus verfahren werden kann.In the area between the superimposed deflection rollers 50 and 51 in the area of the input side of the machine frame 1, the yarn layer 2 or the transport plane E runs vertically. In this vertically extending section of the transport plane E and to the side thereof, rail-like guides 4, 5 are provided in the machine frame 1, one above the other. On these rail-like guides 4 and 5, a support 53 is slidably mounted and at right angles to the plane of the drawing, a stationary but rotatably mounted threaded spindle 16, which is parallel to the rail-like guides 4 and 5, is used for this displacement, which is shown by a motor shown in simplified form 17 can be driven in both directions of rotation, so that this support 53 can be moved both into the drawing plane and out of this drawing plane.

Dieser Support 53 trägt eine Näheinrichtung 54 mit einem Nadelkopf 6 und einem Schiffchenkopf 9, die beide über ein relativ kurzes Joch 10 miteinander verbunden sind, wobei in diesem Joch 10, wie bei Näheinrichtungen dieser Art üblich, die Antriebsmechanik für die Nadel und das Schiffchen bzw. den Greifer untergebracht ist. Zum Antrieb dieser Mechanik dient ein am Joch 10 angeflanschter Motor 11. Beim gezeigten Ausführungsbeispiel trägt der Nadelkopf 6 zwei Nadeln 7 und 8, welche gegenüber der Transportebene E verschiedene Abstände aufweisen und welche darüberhinaus rechtwinkelig zur Zeichenebene gesehen auch gegeneinander versetzt sind.This support 53 carries a sewing device 54 with a needle head 6 and a shuttle head 9, both of which are connected to one another via a relatively short yoke 10, the drive mechanism for the needle and the shuttle or, respectively, in this yoke 10, as is usual with sewing devices of this type the gripper is housed. A motor 11 flanged to the yoke 10 is used to drive this mechanism. In the exemplary embodiment shown, the needle head 6 carries two needles 7 and 8, which have different distances from the transport plane E and which are also offset from one another at right angles to the plane of the drawing.

Die Nadeln 7 und 8 führen den Oberfaden, die Schiffchen oder Greifer einen Unterfaden. Unter Nadelkopf im Sinne der gegenständlichen Erfindung wird eine Mechanik verstanden wie sie von Nähmaschinen her bekannt ist. Die Nadeln sind in ihrer Achsrichtung bewegbar und tragen nahe ihrem spitzen Ende eine Öse, durch welche der sogenannte Oberfaden geschlungen ist. Unter Schiffchenkopf im Sinne dieser Erfindung wird eine mechanische Einrichtung verstanden, in welcher Schiffchen oder Greifer gelagert sind, die einen Unterfaden führen und die mit der hin- und hergehenden Nadel zur Bildung eines Stiches in herkömmlicherweise zusammenwirken. Für den hier vorgesehenen Zweck kann auf diesem Support 53 eine handelsübliche Nähmaschine mit einem Doppelnadelsatz verwendet werden.The needles 7 and 8 guide the upper thread, the shuttle or looper a lower thread. A needle head in the sense of the present invention is understood to mean a mechanism as is known from sewing machines. The needles can be moved in their axial direction and have an eyelet near their pointed end through which the so-called upper thread is looped. For the purposes of this invention, the shuttle head is understood to mean a mechanical device in which shuttle or gripper are mounted, which guide a lower thread and which cooperate with the reciprocating needle to form a stitch in the conventional manner. For the purpose provided here, a commercially available sewing machine with a double needle set can be used on this support 53.

Seitlich der Nadeln 7 und 8 des Nadelkopfes 6 und zwar auf der der Transportebene E abgewandten Seite erstreckt sich über die gesamte Breite des Maschinengestelles 1 ein Tragholm 25 mit einer Klemmeinrichtung 56. Diese Klemmeinrichtung besitzt eine über ein oder mehrere Hubzylinder 60 heb- und senkbare Klemmleiste 58, die über ihre Länge mit mehreren nadelartigen Stiften 59 bestückt ist, die voneinander distanziert sind (in Fig. 8 rechtwinkelig zur Zeichenebene).On the side of the needles 7 and 8 of the needle head 6, namely on the side facing away from the transport plane E, a support bar 25 with a clamping device 56 extends over the entire width of the machine frame 1. This clamping device has a clamping bar that can be raised and lowered via one or more lifting cylinders 60 58, which is equipped over its length with a plurality of needle-like pins 59 which are spaced apart (at right angles to the plane of the drawing in FIG. 8).

Zwischen der Transportebene E der Garnlage 2 und der Näheinrichtung 54 ist ein Walzenpaar aus den beiden übereinander liegenden Walzen 61 und 62 vorgesehen, wobei sich die Achsen dieser Walzen parallel zu den Führungen 4 und 5 erstrekken. Die eine Walze 61 liegt dabei oberhalb und die andere Walze 62 unterhalb der rechtwinkelig zur Arbeitsrichtung der Nähnadeln 7 und 8 stehenden, gedachten Nähebene, die hier am Ausführungsbeispiel nach Fig. 7 als horizontal liegende und rechtwinkelig zur Zeichenebene stehende Ebene zu denken ist. Die beiden Walzen 61 und 62, die übereinander liegen, sind voneinander distanziert, sie sind jedoch in der Ebene, die ihre Achsen enthält, zur Verringerung ihres gegenseitigen Abstandes gegeneinander verstellbar. Die dazu dienende Mechanik ist hier aus Gründen der Übersichtlichkeitwegen nicht dargestellt. Die Verstellung einer Walze kann beispielsweise dadurch erreicht werden, daß die Welle oder Achse der Walze an ihren äußeren Enden in Lagerböcken frei drehbar gelagert sind, und diese Lagerböcke entlang des Maschinengestelles vertikal verschiebbar gelagert sind, wobei für diese Verschiebung ein Hubzylinder verwendet werden kann, dessen eine Ende am Maschinengestell und dessen andere Ende am Lagerbock befestigt ist.Between the transport plane E of the yarn ply 2 and the sewing device 54, a pair of rollers from the two superposed rollers 61 and 62 is provided, the axes of these rollers extending parallel to the guides 4 and 5. One roller 61 is above and the other roller 62 is below the imaginary sewing plane, which is perpendicular to the working direction of the sewing needles 7 and 8, which is to be thought of as the horizontal plane at right angles to the plane of the drawing in the embodiment of FIG. 7. The two rollers 61 and 62, which lie one above the other, are spaced apart from one another, but are adjustable relative to one another in the plane containing their axes in order to reduce their mutual distance. The mechanics used for this are not shown here for reasons of clarity. The adjustment of a roller can be achieved, for example, in that the shaft or axis of the roller are freely rotatably supported at their outer ends in bearing blocks, and these bearing blocks are mounted so as to be vertically displaceable along the machine frame, a lifting cylinder being used for this displacement one end is attached to the machine frame and the other end to the bearing block.

Nahe bzw. in der erwähnten Nähebene liegt ein Schieber 63 und zwar auf der der Näheinrichtung 54 abgewandten Seite der Transportebene E, der in dieser Ebene bzw. parallel dazu verschiebbar ist und zwar mittels einer Kolben-Zylinder-Einheit 64. Dieser Schieber 63, der sich ebenfalls über die gesamte Breite der Vorrichtung erstreckt, besitzt prallel zu seiner Verschieberichtung 65 verlaufende Schlitze 66, die von seinem stirnseitigen Rand 67 ausgehen, das ist der der Transportebene E benachbarte und zu ihr parallel verlaufende Rand dieses Schiebers. Bei diesem Schieber handelt es sich, wie Fig. 9 anschaulich macht, um ein langgestrecktes leistenartiges Bauglied. Die gegenseitigen Abstände a dieser Schlitze 66 entsprechen den Abständen der nadelartigen Stifte 59 an der Klemmleiste 58.A slider 63 is located near or in the mentioned sewing plane, namely on the side of the transport plane E facing away from the sewing device 54, which can be displaced in this plane or parallel thereto by means of a piston-cylinder unit 64. This slider 63, the also extends over the entire width of the device, has slots 66 running parallel to its direction of displacement 65, which extend from its end edge 67, that is the one adjacent to the transport plane E and parallel to it fende edge of this slider. This slide is, as FIG. 9 shows, an elongated strip-like member. The mutual distances a between these slots 66 correspond to the distances between the needle-like pins 59 on the terminal strip 58.

Im gezeigten Ausführungsbeispiel nach Fig. 7 ist unterhalb des Schiebers 63 die Haltevorrichtung 18 angeordnet mit einem feststehenden leistenförmigen Klemmbacken 21 und einem bewegbaren ebenfalls leistenförmigen Klemmbacken 22, der mittels der Kolben-Zylinder-Einheit 68 gegen den feststehenden Klemmbacken 21 gedrückt werden kann.In the exemplary embodiment shown in FIG. 7, the holding device 18 is arranged below the slide 63 with a fixed strip-shaped clamping jaw 21 and a movable, likewise strip-shaped clamping jaw 22, which can be pressed against the fixed clamping jaw 21 by means of the piston-cylinder unit 68.

Grundsätzlich ist es denkbar und das sei an dieser Stelle erwähnt, daß diese Haltevorrichtung 18 unmittelbar am Schieber 63 angeordnet sein kann, wobei beispielsweise der Schieber 63 die feststehende Klemmleiste bildet.Basically, it is conceivable and it should be mentioned at this point that this holding device 18 can be arranged directly on the slide 63, for example the slide 63 forming the fixed terminal strip.

Oberhalb des Schiebers 63 ist am oder im Maschinengestell 1 eine weitere Umlenkwalze 24 frei drehbar gelagert.Above the slider 63, a further deflection roller 24 is freely rotatably mounted on or in the machine frame 1.

Vor dem Maschinengestell 1 der Vorrichtung und ebenfalls unterhalb der Transportbahn E ist ein Wagen 25 rechtwinkelig zur Zeichenebene nach Fig. 7 verfahrbar gelagert, der eine Vorratsrolle 26 trägt, auf welcher das bahn- oder schichtförmige Material 19 aufgewickelt ist.In front of the machine frame 1 of the device and also below the transport path E, a carriage 25 is mounted so as to be movable at right angles to the plane of the drawing according to FIG. 7, which carries a supply roll 26 on which the web or layered material 19 is wound.

Im Bereich der Walzen 61 und 62 des Walzenpaares ist ein weiteres Klemmleistenpaar 27 vorgesehen, an welchem ein Stoffstreifen 41 mit seinem oberen Rand festgeklemmt ist. Dieser Stoffstreifen 41 hängt frei nach unten und liegt zwischen der Transportebene E und den Walzen 61 und 62 des Walzenpaares und erstreckt sich zweckmäßigerweise über diese nach unten, wie dies hier in Fig. 7 dargestellt ist.In the area of the rollers 61 and 62 of the pair of rollers, a further pair of clamping strips 27 is provided, on which a strip of fabric 41 is clamped with its upper edge. This strip of fabric 41 hangs freely downwards and lies between the transport plane E and the rollers 61 and 62 of the pair of rollers and expediently extends downwards over these, as is shown here in FIG. 7.

Auf der Seite des Maschinengestelles 1, die der Garnbehandlungsanlage zugewandt ist, ist noch eine Klemmeinrichtung 37 zwischen den beiden Umlenkwalzen 52 und 40 vorgesehen, durch deren beide Klemmbacken die Transportebene E bzw. die Garnlage 2 verläuft. Eine Kolben-Zylinder-Einheit 38 dient auch hier zur Betätigung dieser Klemmeinrichtung. Auf der Eingangsseite der Vorrichtung bzw. des Maschinengestelles 1, ist noch eine Schneidleiste 39 vorgesehen, deren Betätigungseinrichtung hier jedoch nicht dargestellt ist. Soweit zum konstruktiven Aufbau der Vorrichtung.On the side of the machine frame 1 which faces the yarn treatment system, a clamping device 37 is also provided between the two deflecting rollers 52 and 40, through the two clamping jaws of which the transport plane E or the yarn layer 2 runs. A piston-cylinder unit 38 also serves to actuate this clamping device. On the input side of the device or of the machine frame 1, a cutting bar 39 is also provided, the actuating device of which, however, is not shown here. So much for the construction of the device.

Im folgenden wird nun die Arbeitsweise dieser Vorrichtung beschrieben: Eine parallele Faden-oder Garnschar, hier als Garnlage 2 bezeichnet, läuft von nicht dargestellten Zettelbäumen ab und von links her (Fig. 7) in die Vorrichtung ein, über frei drehbare Umlenkwalzen 50, 51, 52 durch diese hindurch und anschließend über eine weitere Umlenkwalze 40 in die eigentliche Garnbehandlungsanlage mit dem vorgeschalteten Kompensator 20, wo sie den eigentlichen Bearbeitungsvorgängen nacheinander unterworfen wird. Auf dem aufgezeigten Weg geht die Garnlage 2 durch die vorstehend erläuterten Teile hindurch, deren Zusammenwirken nachstehend nun erläutert wird. Vorausgeschickt wird dabei, daß die Fig. 7 diese Teile in ihrer jeweiligen Stellung zeigt, die sie während des normalen Arbeitsablaufes einnehmen, d.h. die Schneidleiste 39 und die Klemmvorrichtung 37 sind geöffnet, die Klemmleiste 58 ist angehoben, ebenso die Nadeln 7 und 8 des Nadelkopfes 6 und der Antriebsmotor 7 steht still. Auf der Vorratsrolle 26 ist eine Stoffbahn aufgewickelt und ein Stück dieser Stoffbahn 19 ist abgezogen, über die Umlenkrolle 24 und am Schieber 63 vorbeigeführt und das freie Ende ist in der Haltevorrichtung 18 eingespannt. Diese Stoffbahn 19 ist etwas gespannt, da sie von der Vorratsrolle 26 gegen die Wirkung einer dort angeordneten, jedoch nicht dargestellten Abzugsbremse abgezogen ist. Ferner ist vom Klemmleistenpaar 27 ein Stoffstreifen 41 festgehalten, der frei nach unten hängt, wie schon oben beschrieben. Diese Anordnung betrifft und zeigt die Vorrichtung dann, wenn die Garnlage 2 die Behandlungsanlage ordnungsgemäß durchläuft, und auf den nicht dargestellten Zettelbäumen noch ein hinreichender Garnvorrat vorhanden ist.The mode of operation of this device is now described below: A parallel group of threads or yarn, here referred to as yarn layer 2, runs from slip trees (not shown) and enters the device from the left (FIG. 7), via freely rotatable deflection rollers 50, 51 , 52 through this and then via a further deflection roller 40 into the actual yarn treatment plant with the upstream compensator 20, where it is subjected to the actual processing operations one after the other. On the path shown, the yarn layer 2 passes through the parts explained above, the interaction of which will now be explained below. It is anticipated that Fig. 7 shows these parts in their respective positions which they assume during the normal work process, i.e. the cutting bar 39 and the clamping device 37 are open, the clamping bar 58 is raised, as are the needles 7 and 8 of the needle head 6 and the drive motor 7 is at a standstill. A fabric web is wound on the supply roll 26 and a piece of this fabric web 19 is pulled off, guided over the deflection roller 24 and past the slide 63, and the free end is clamped in the holding device 18. This fabric web 19 is somewhat tense because it is pulled off the supply roll 26 against the action of a trigger brake arranged there but not shown. Furthermore, a strip of fabric 41 is held by the pair of terminal strips 27, which hangs freely downward, as already described above. This arrangement concerns and shows the device when the yarn layer 2 passes through the treatment plant properly and there is still sufficient yarn supply on the slip trees, not shown.

Geht nun aber die Garnlage 2 zu Ende, so muß nun die notwendige Verbindung mit dem Material 19 hergestellt werden und es wird nun vorerst der weitere Lauf der Garnlage 2 durch die erfindungsgemäße Vorrichtung gestoppt, indem die Klemmvorrichtung 37 betätigt wird, die sich schließt und die nun die Garnlage 2 festhält, indem diese zwischen den beiden Backen eingeklemmt wird. Die Garnlage 2, in Fig. 7 links der Klemmeinrichtung 37 bleibt jedoch gespannt, bedingt durch den Abwicklungswiderstand von den Zettelbäumen oder eventuell durch eigene hier nicht vorgesehene Abzugsbremsen. Der Behandlungsvorgang jedoch in der Behandlungsanlage läuft ungehindert weiter, denn im Kompensator 20 ist dafür eine hinreichende Menge der zu behandelnden Garnlage bevorratet.But now the yarn layer 2 is coming to an end, the necessary connection must now be made with the material 19 and the further running of the yarn layer 2 is now stopped by the device according to the invention by actuating the clamping device 37, which closes and the now hold the thread ply 2 by pinching it between the two jaws. The layer of yarn 2, in FIG. 7 to the left of the clamping device 37, remains tense, however, due to the unwinding resistance of the slip trees or possibly due to own trigger brakes not provided here. However, the treatment process in the treatment plant continues unimpeded, because a sufficient amount of the yarn layer to be treated is stored in the compensator 20.

Nun wird die Kolben-Zylinder-Einheit 64 beaufschlagt mit der Folge, daß der Schieber 63 nach rechts fährt und dabei zieht er nicht nur einen Teil der Materialbahn 19 mit, sondern auch die Garnlage 2 und den frei nach unten hängenden Stoffstreifen 41 (Fig. 8) und schiebt diese durch die beiden voneinander distanzierten Walzen 61 und 62 hindurch, bis seine Vorderkante 67 die Klemmleiste 58 der Klemmvorrichtung 56 unterfahren hat. Dabei fährt gleichzeitig die untere Umlenkwalze 51 und eventuell auch die Umlenkwalze 52 etwas nach oben, so daß dadurch ein ausreichender "Materialvorrat" frei wird, um die aus Fig. 8 ersichtliche seitliche Verdrängung der Materialbahnen zu ermöglichen. Nun wird anschließend die Klemmleiste 58 gesenkt und dabei durchstechen die nadelartigen Stifte 59 die mehrfache Materialbahn (Fig. 8), wobei die niederfahrenden Stifte 59 von den Schlitzen 66 des Schiebers 63 aufgenommen werden. Nun fährt der Schieber 63 wieder in seine Ausgangslage zurück und die Material- und Garnlagen sind durch die Stifte 59 festgehalten und anschließend fahren die Walzen 61 und 62 gegeneinander und zusammen, so daß die Material- und Garnlagen zwischen diesen Walzen 61 und 62 und den Stiften 59 der Klemmeinrichtung 56 nahe aufeinander liegen.Now the piston-cylinder unit 64 is acted on with the result that the slide 63 moves to the right and in doing so it not only pulls part of the material web 19 with it, but also the yarn layer 2 and the freely hanging fabric strip 41 (FIG. 8) and pushes them through the two spaced-apart rollers 61 and 62 until its front edge 67 has passed under the clamping bar 58 of the clamping device 56. At the same time, the lower deflecting roller 51 and possibly also the deflecting roller 52 move somewhat upwards, so that a sufficient "material supply" is released to enable the lateral displacement of the material webs shown in FIG. 8. Now the clamping strip 58 is then lowered and the needle-like pins 59 pierce the multiple material web (FIG. 8), the descending pins 59 being received by the slots 66 of the slide 63. Now the slide 63 moves back into its starting position and the material and yarn layers are held in place by the pins 59 and then the rollers 61 and 62 move against each other the and together, so that the material and yarn layers between these rollers 61 and 62 and the pins 59 of the clamping device 56 are close to each other.

Nun werden die Antriebsmotoren 11 für die Näheinrichtung und der Antriebsmotor 17 für die Verschiebung derselben eingeschaltet und die drei erwähnten Teile 2, 19 und 41 werden nun zusammengenäht, und zwar bei einem Bewegungsablauf der Näheinrichtung durch zwei Nähte, die aufgrund der gewählten Anordnung der Nadeln 7 und 8 gegeneinander versetzt liegen. Hat die Näheinrichtung 54, bestehend aus den Köpfen 6 und 9 und ausgehend von ihrer einen Ausgangslage ihre anderseitige Endstellung erreicht, so wird der Antriebsmotor 11 für die Näheinrichtung bei hochgezogenen Nadeln stillgesetzt, die Walzen 61 und 62 fahren wieder in ihre Ausgangsstellung zurück und die Klemmleiste 58 wird angehoben. Anschließend wird nun die Garnlage 2 selbst durch Betätigung der Schneidleiste 39 durchtrennt und dann die Klemmvorrichtung 37 wieder geöffnet. Die von der Garnbehandlungsanlage her wirkende Einzugskraft zieht nun über die in dieser Behandlungsanlage noch laufende Garnlage 2 den Stoff 19 von der Vorratsrolle 26 ab. Dieser Stoff 19 hat bei dem hier nicht näher beschriebenen Garnbehandlungsverfahren nur die Aufgabe, als Produktionshilfsmittel zu dienen und er ist wiederholt verwendbar und verwertbar. Dazu kann ein normaler einfacher Stoff verwendet werden, der aus Kett- und Schußfäden gebildet ist, es sind aber auch andere Materialien denkbar, beispielsweise Schichtmaterialien, wie Kunststoff-Folien od. dgl.Now the drive motors 11 for the sewing device and the drive motor 17 for shifting the same are switched on and the three parts 2, 19 and 41 mentioned are now sewn together, namely during a movement sequence of the sewing device by means of two seams which, due to the selected arrangement of the needles 7 and 8 are offset from each other. When the sewing device 54, consisting of the heads 6 and 9 and starting from its one starting position, has reached its other end position, the drive motor 11 for the sewing device is stopped when the needles are raised, the rollers 61 and 62 move back into their starting position and the clamping strip 58 is raised. Subsequently, the yarn layer 2 itself is cut by actuating the cutting bar 39 and then the clamping device 37 is opened again. The pulling force acting from the yarn treatment plant now pulls the substance 19 off the supply roll 26 via the yarn layer 2 still running in this treatment plant. In the yarn treatment process, which is not described in more detail here, this substance 19 has only the task of serving as a production aid and it can be used and used repeatedly. For this purpose, a normal simple fabric can be used, which is formed from warp and weft threads, but other materials are also conceivable, for example layer materials, such as plastic films or the like.

Eine Verbindung zwischen dem Material 19, dem Stoffstreifen 41 und der Garnlage 2 zeigt Fig. 10 in Schrägsicht. Die hier vorhandenen beiden Nähte sind gegeneinander versetzt. Wie Zugversuche mit derart hergestellten Verbindungen zeigen, sind diese außerordentlich belastungsfähig. Diese Verbindungen, wie vorstehend beschrieben und in Fig. 10 veranschaulicht, besteht aus den erwähnten gegeneinander versetzten Nähten und den beiden Stoffen 19 und 41, zwischen welchen die Garnlage 2 gehalten ist. Es ist auch möglich, im Nadelkopf mehr als zwei Nadeln anzuordnen, so daß bei einem Lauf der Näheinrichtung gleichzeitig mehr als zwei Nähte hergestellt werden können.A connection between the material 19, the fabric strip 41 and the yarn layer 2 is shown in FIG. 10 in an oblique view. The two seams here are offset from one another. As tensile tests with connections made in this way show, these are extremely resilient. This connection, as described above and illustrated in Fig. 10, consists of the mentioned mutually offset seams and the two fabrics 19 and 41, between which the yarn layer 2 is held. It is also possible to arrange more than two needles in the needle head, so that more than two seams can be produced at the same time in one run of the sewing device.

Der obere Stoffstreifen 41 übernimmt in dieser Verbindung zwei Aufgaben, einmal dient er als eigentliches Verbindungselement und ferner dient er dazu, dem Niederhalter, der jeder Nadel zugeordnet ist, ein ungehindertes Gleiten über das zu vernähende Material zu ermöglichen. Falls an die Zugfestigkeit der Verbindung keine allzu großen Anforderungen gestellt werden, ist es durchaus denkbar, bei der Herstellung dieser Verbindung den oberen Streifen 41 wegzulassen. Damit in diesem Falle ohne Schwierigkeiten genäht werden kann, ist vorgesehen, daß der mit der Nähnadel des Nadelkopfes 6 zusammenwirkende Niederhalter (siehe Fig. 6) als frei drehbar gelagerte Scheibe 45 ausgebildet ist, deren Drehachse 46 rechtwinkelig zur Transportrichtung (Pfeil 3) der Garnlage 2 liegt.The upper fabric strip 41 takes on two tasks in this connection, first it serves as the actual connecting element and it also serves to enable the hold-down device, which is assigned to each needle, to slide freely over the material to be sewn. If the tensile strength of the connection is not too high, it is quite conceivable to omit the upper strip 41 when making this connection. So that sewing can be carried out without difficulty in this case, it is provided that the holding-down device cooperating with the sewing needle of the needle head 6 (see FIG. 6) is designed as a freely rotatable disc 45, the axis of rotation 46 of which is perpendicular to the direction of transport (arrow 3) of the thread layer 2 lies.

Die Führungen 4 und 5 sind länger als die Breite der zu behandelnden Bahnen, so daß im Bedarfsfalle die Näheinrichtung gänzlich zur Seite gefahren werden kann, wodurch das Arbeiten innerhalb des Maschinengestelles 1 erleichtert wird.The guides 4 and 5 are longer than the width of the webs to be treated, so that, if necessary, the sewing device can be moved entirely to the side, which makes working within the machine frame 1 easier.

Durchläuft beim erstbesprochenen Ausführungsbeispiel die Garnlage 2 die Vorrichtung in einer Horizontalebene, so ist es möglich, die Anordnung so zu treffen, daß die Garnlage 2 diese Vorrichtung in vertikaler Richtung durchläuft. In diesem Falle wird die Vorrichtung als Ganzes oder zumindest einzelner Teile um 90° gedreht. Eine weitere Anordnung im Rahmen der Erfindung liegt darin, die Anordnung so zu treffen, daß zwischen der Transportebene E bzw, der Garnlage 2 und dem Nadelkopf 6 das bahnförmige oder schichtförmige Material 19 liegt. In diesem Fall kann der schmale Stoffstreifen 41 direkt über dem Schiffchenkopf aufgespannt werden.If the yarn layer 2 passes through the device in a horizontal plane in the first-discussed exemplary embodiment, it is possible to make the arrangement so that the yarn layer 2 passes through this device in the vertical direction. In this case, the device as a whole or at least individual parts is rotated through 90 °. Another arrangement within the scope of the invention is to make the arrangement such that the web-shaped or layered material 19 lies between the transport plane E or the yarn layer 2 and the needle head 6. In this case, the narrow strip of fabric 41 can be stretched directly over the head of the boat.

Durchläuft beim zweitbesprochenen Ausführungsbeispiel die Garnlage 2 die Vorrichtung in dem hier interessierenden Arbeitsbereich in einer Vertikalebene, so ist es durchaus möglich, die Anordnung so zu treffen, daß die Garnlage 2 diese Vorrichtung in diesem Bereich in horizontaler Richtung durchläuft. In diesem Fall wird die Vorrichtung als Ganzes oder zumindest einzelne Teile derselben um 90° gedreht. Eine weitere Anordnung im Rahmen der Erfindung liegt darin, sie so zu treffen, daß bezüglich einer unmittelbar über dem horizontalen Einlaufteil der Garnlage liegenden gedachten Achse, in Fig. 7 dargestellt durch eine --..-- Linie 69, die vorstehend beschriebenen Gerätschaften noch einmal spiegelbildlich angeordnet werden. Im zweiten Ausführungsbeispiel ist gezeigt, daß die Haltevorrichtung 18 am Maschinengestell gelagert ist. Es ist aber auch denkbar und möglich, die Klemmbakken 21 und 22 dieser Haltevorrichtung einschließlich der dazugehörenden Kolben-Zylinder-Einheiten 68 am horizontal gewegbaren Schieber 63 vorzusehen, so daß sich in der Folge das festgeklemmte Ende der Materialbahn 19 zusammen mit dem Schieber bewegt.If, in the second exemplary embodiment discussed, the yarn layer 2 passes through the device in the work area of interest in a vertical plane, it is entirely possible to arrange the yarn layer 2 through this device in this area in the horizontal direction. In this case, the device as a whole or at least individual parts thereof is rotated through 90 °. Another arrangement within the scope of the invention is to make it so that, with respect to an imaginary axis lying directly above the horizontal inlet part of the yarn ply, represented in FIG. 7 by a -. Line 69, the devices described above once arranged in mirror image. In the second embodiment it is shown that the holding device 18 is mounted on the machine frame. However, it is also conceivable and possible to provide the clamping jaws 21 and 22 of this holding device including the associated piston-cylinder units 68 on the horizontally movable slide 63, so that the clamped end of the material web 19 moves together with the slide.

Die gegenständliche Vorrichtung wurde entwikkelt, um Garnlagen der vorstehend beschriebenen Art mit schicht- oder bahnförmigen Materialien möglichst billig zu verbinden. Das schließt natürlich nicht aus, daß die erfindungsgemäße Vorrichtung auch dazu verwendet wird, Gewebebahnen untereinander zu verbinden, auch dafür ist die gegenständliche Einrichtung uneingeschränkt nutzbar.The device in question was developed in order to connect yarn layers of the type described above with layered or web-shaped materials as cheaply as possible. Of course, this does not exclude that the device according to the invention is also used to connect fabric webs to one another, and the device in question can also be used without restriction for this.
