Description

Die Erfindung betrifft eine Fadenklemmeinrichtung gemäß dem Oberbegriff des Anspruchs 1 oder 2. Die Erfindung betrifft weiterhin ein Verfahren zum Klemmen wenigstens eines Fadens in einer Textilmaschine.The invention relates to a thread clamping device according to the preamble of claim 1 or 2. The invention further relates to a method for clamping at least one thread in a textile machine.

Aus der DE-A-15 85 356 ist in Zusammenhang mit Flachkolierwirkmaschinen eine Vorrichtung zum selbstätigen Abtrennen und Halten von Fäden bekannt, bei der ein einziges, auf den Warenrand während des Arbeitsprozesses einstellbares Paar von Brennelementen für das Abtrennen aller Fäden in unmittelbarer Nähe der beiden Warenränder vorgesehen ist.From DE-A-15 85 356, in connection with flat-pile warp knitting machines, a device for the automatic cutting and holding of threads is known, in which a single pair of fuel elements that can be adjusted to the edge of the goods during the working process for the separation of all threads in the immediate vicinity of the two Goods edges are provided.

Eine weitere Fadenklemmeinrichtung ist in Zusammenhang mit einer Flachstrickmaschine aus der JP 22 69 848 A2 bekannt. Für jeden zu klemmenden Faden ist eine eigene Klemmvorrichtung mit jeweils eigenen Steuer- und Antriebseinrichtungen vorgesehen. Die einzelnen Klemmvorrichtungen weisen einen komplizierten mechanischen Aufbau auf. Darüberhinaus sind die Antriebseinrichtungen und Steuervorgänge kompliziert und umständlich, weil für jeden zu klemmenden Faden jeweils eine eigene Klemmvorrichtung, die geöffnet und geschlossen werden muß, Antriebseinrichtung und Steueranordnung erforderlich ist. Eine weiterer wesentlicher Nachteil dieser herkömmlichen Klemmvorrichtungen besteht darin, daß sie relativ viel Platz beanspruchen, der in vielen Fällen nicht vorhanden ist. Bei der Verwendung derartiger Klemmvorrichtungen in Zusammenhang mit Flachstrickmaschine ist daher die Anzahl der Klemmvorrichtungen begrenzt, sodaß nur wenige Fäden geklemmt werden können.Another thread clamping device is known in connection with a flat knitting machine from JP 22 69 848 A2. A separate clamping device with its own control and drive devices is provided for each thread to be clamped. The individual clamping devices have a complicated mechanical structure. In addition, the drive devices and control processes are complicated and cumbersome, because for each thread to be clamped, a separate clamping device that has to be opened and closed, drive device and control arrangement is required. Another major disadvantage of these conventional clamping devices is that they take up a relatively large amount of space, which in many cases is not available. When using such clamping devices in connection with flat knitting machines, the number of clamping devices is therefore limited, so that only a few threads can be clamped.

Der Erfindung liegt die Aufgabe zugrunde, eine Fadenklemmeinrichtung zu schaffen und ein Verfahren zum Klemmen von Fäden anzugeben, mit der bzw. mit dem es auf einfache Weise und mit geringem mechanischen, konstruktiven und steuertechnischen Aufwand möglich ist, eine große Anzahl von Fäden in einer Textilmaschine zu halten bzw. zu klemmen.The invention has for its object to provide a thread clamping device and to provide a method for clamping threads with which or with which it is possible in a simple manner and with little mechanical, constructive and control engineering effort, a large number of threads in a textile machine to hold or clamp.

Die gestellte Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 oder des Anspruches 2 gelöst.The object is achieved according to the invention by the characterizing features of claim 1 or claim 2.

Die erfindungsgemäße Klemmbandvorrichtung ist sowohl hinsichtlich des konstruktiven als auch des steuertechnischen Aufwands denkbar einfach. Besonders vorteilhaft ist es jedoch, daß für eine Vielzahl von Fäden, die geklemmt werden sollen, nur eine einzige Vorrichtung benötigt wird. Dadurch fällt die bei herkömmlichen Fadenklemmeinrichtungen vorhandenen Beschränkungen auf das Klemmen nur einer bestimmten Anzahl von Fäden weg. Das zu klemmende Band kann nämlich immer dann, wenn ein neuer zu klemmender Faden geklemmt werden soll, um einen bestimmten Weg weiterbewegt werden, sodaß die geklemmten Fäden in der Klemmbandvorrichtung nacheinander geklemmt und gehalten in ihr liegen. Gemäß einer sehr vorteilhaften Ausführungsform der Erfindung weist die Klemmbandvorrichtung Klemmbänder auf, die im Fadenklemmbereich gegeneinander gedrückt und in gleicher Bandlaufrichtung bewegbar sind. Obgleich es grundsätzlich möglich ist, nur ein Klemmband zu verwenden, welches die zu klemmenden Fäden zwischen sich und einer starren Fläche hält, ist die Verwendung zweier im Fadenklemmbereich in gleicher Bandlaufrichtung bewegter Klemmbänder vorteilhafter, weil dadurch auf beiden Seiten der zu klemmenden Fäden eine gleichgerichtete Bewegung möglich ist.The clamping band device according to the invention is very simple, both in terms of construction and in terms of control technology. However, it is particularly advantageous that only a single device is required for a large number of threads which are to be clamped. This eliminates the restrictions on conventional clamping of only a certain number of threads. The band to be clamped can namely be moved a certain distance whenever a new thread to be clamped is to be clamped, so that the clamped threads are clamped one after the other in the clamping band device and held in it. According to a very advantageous embodiment of the invention, the clamping band device has clamping bands which are pressed against one another in the thread clamping area and can be moved in the same direction of travel of the band. Although it is fundamentally possible to use only one clamping band, which holds the threads to be clamped between themselves and a rigid surface, the use of two clamping bands moving in the same direction of travel in the thread clamping area is more advantageous, because this results in a directional movement on both sides of the threads to be clamped is possible.

Der Bandlauf des wenigstens einen Klemmbandes ist vorzugsweise mit einem Schrittmotor steuerbar. Vorzugsweise sind die Laufgeschwindigkeiten und die Zeiträume, in denen die beiden gegeneinander gedrückten Klemmbänder bewegt werden, für die beiden Klemmbänder gleich.The belt run of the at least one clamping band can preferably be controlled with a stepper motor. The running speeds and the periods in which the two clamping bands pressed against one another are preferably the same for the two clamping bands.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist wenigstens ein beweglicher Haken zum Zuführen des zu klemmenden Fadens im Klemmbereich der Klemmbandvorrichtung vorgesehen. Der bewegliche Fadenzuführhaken wird dabei so gesteuert, daß er dann, wenn der Faden geklemmt werden soll, so betätigt wird, daß der zu klemmende Faden in den Klemmbereich der Klemmbandvorrichtung gelangt und von dieser ergriffen werden kann. Obgleich ein beweglicher Fadenzuführhaken für das Zuführen des zu klemmenden Faden in den Klemmbereich der Klemmbandvorrichtung ausreicht, ist es jedoch vorteilhafter, auf beiden Seiten der Klemmbandvorrichtung je einen Fadenzuführhaken vorzusehen. Dadurch kann der zu klemmende Faden quer zur Bewegungsrichtung der Klemmbänder eingelegt werden, sodaß der Faden gleichmäßig und definiert von der Klemmbandvorrichtung bewegt und gehalten wird. Wenigstens einer dieser Fadenzuführhaken ist insbesondere auch dann von Vorteil, wenn Schneid- oder Scher-Einrichtungen für den Faden vorhanden sind. Wenigstens einer dieser Fadenzuführhaken ermöglicht es, daß der zu schneidende Faden tief und zuverlässig in die geöffnete Schere eingelegt wird.According to a further advantageous embodiment of the invention, at least one movable hook is provided for feeding the thread to be clamped in the clamping area of the clamping band device. The movable thread feed hook is controlled so that, when the thread is to be clamped, it is actuated so that the thread to be clamped gets into the clamping area of the clamping band device and can be gripped by it. Although a movable thread feed hook is sufficient for feeding the thread to be clamped into the clamping area of the clamping band device, however, it is more advantageous to provide a thread supply hook on each side of the clamping band device. As a result, the thread to be clamped can be inserted transversely to the direction of movement of the clamping bands, so that the thread is moved and held uniformly and in a defined manner by the clamping band device. At least one of these thread feed hooks is particularly advantageous even when there are cutting or shearing devices for the thread. At least one of these thread feed hooks enables the thread to be cut to be inserted deeply and reliably into the open scissors.

Der bzw. die Fadenzuführhaken ist bzw. sind vorzugsweise mit wenigstens einem Schrittmotor steuerbar zu bewegen. Obgleich bei Verwendung von zwei Fadenzuführhaken die Bewegung der beiden Haken gleichmäßig und gleichzeitig erfolgt, ist es jedoch auch möglich und in einzelnen Anwendungsfällen vorteilhaft, die einzelnen Fadenzuführhaken getrennt voneinander zu steuern und zu bewegen.The thread feed hook (s) can preferably be moved in a controllable manner with at least one stepper motor. Although the movement of the two hooks takes place evenly and simultaneously when using two thread feed hooks, it is also possible and advantageous in individual applications to control and move the individual thread feed hooks separately from one another.

Gemäß einer sehr vorteilhaften Ausführungsform der Erfindung ist in Zusammenhang mit der Klemmbandvorrichtung eine Fadenschneideinrichung zum Trennen des geklemmten Fadens vorgesehen.According to a very advantageous embodiment of the invention, a thread cutting device for separating the clamped thread is provided in connection with the clamping band device.

Sehr vorteilhaft ist eine Weiterbildung der erfindungsgemäßen Klemmeinrichtung, wonach ein Fadenablenkelement zum Ablenken eines Fadens aus dem Klemmbereich der Klemmbandvorrichtung vorgesehen ist. Das wenigstens eine Fadenablenkelement kann unbeweglich, aber auch beweglich sein, um eine optimale Ablenkung des nicht zu klemmenden Fadens - je nach den gegebenen und gewünschten Möglichkeiten - zu gewährleisten.A further development of the clamping device according to the invention is very advantageous, according to which a thread deflecting element is provided for deflecting a thread from the clamping area of the clamping band device. The at least one thread deflecting element can be immovable, but also movable, in order to ensure optimal deflection of the thread not to be clamped, depending on the given and desired possibilities.

Wenigstens ein Fadenzuführhaken ist vorzugsweise so ausgebildet, daß er auch den abgelenkten Faden ergreifen kann. Beispielsweise ist dies dadurch möglich, daß der Haken breit ausgebildet ist. Dadurch ist es möglich, auch den abgelenkten Faden mit wenigstens einem Fadenzuführhaken zu erfassen und beispielsweise einer Schneidevorrichtung zuzuführen.At least one thread feed hook is preferably designed so that it can also grip the deflected thread. For example, this is possible because the hook is wide. This makes it possible to grasp the deflected thread with at least one thread feed hook and, for example, to feed it to a cutting device.

Die erfindungsgemäße Fadenklemmeinrichtung ist vorteilhaft in Zusammenhang mit einer Nadelbetten aufweisenden Flachstrickmaschine einsetzbar. In diesem Falle ist die erfindungsgemäße Klemmbandvorrichtung auf wenigstens einer Seite der Flachstrickmaschine am seitlichen Ende der Nadelbetten angeordnet.The thread clamping device according to the invention can advantageously be used in connection with a flat knitting machine having needle beds. In this case, the clamping band device according to the invention is arranged on at least one side of the flat knitting machine at the lateral end of the needle beds.

Die Klemmbandvorrichtung ist vorzugsweise unterhalb einer durch den Strickbereich vorgegebenen Ebene vorgesehen. Dadurch werden die zu klemmenden Fäden unterhalb dieser durch den Strickbereich vorgegebenen Ebene gehalten.The clamping band device is preferably provided below a level predetermined by the knitting area. As a result, the threads to be clamped are kept below this level predetermined by the knitting area.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Schneidevorrichtung vorzugsweise zwischen der Klemmbandeinrichtung und den Nadelbetten bzw. dem Strickbereich angeordnet.According to a further advantageous embodiment of the invention, the cutting device is preferably arranged between the clamping band device and the needle beds or the knitting area.

In Zusammenhang mit der Verwendung der erfindungsgemäßen Klemmbandvorrichtung bei Flachstrickmaschinen ist ein Abstellbereich für die Nüßchen mit den zu klemmenden und/oder zu schneidenden Fäden auf der dem Nadelbett abgewandten Seite der Klemmbandeinrichtung vorgesehen. Die Nüßchen mit den Fäden, die für den Strickvorgang momentan nicht benutzt werden, "parken" außerhalb des Nadelbereichs der Strickmaschine solange, bis die Nüßchen mit ihren Fadenführerkästchen wieder in den Nadelbereich bewegt werden.In connection with the use of the clamping band device according to the invention in flat knitting machines, a storage area for the nuts with the threads to be clamped and / or cut is provided on the side of the clamping band device facing away from the needle bed. The sockets with the threads that are not currently used for the knitting process "park" outside the needle area of the knitting machine until the sockets with their thread guide boxes are moved back into the needle area.

Vorteilhaft ist es weiterhin, einen Abstellbereich für Nüßchen vorzusehen, deren Fäden nicht geklemmt und/oder geschnitten werden sollen, wobei der Abstellbereich für diese Nüßchen auf der dem Nadelbetten zugewandten Seite der Klemmband- und/oder Schneidevorrichtung vorgesehen ist.It is also advantageous to provide a storage area for nuts, the threads of which are not pinched and / or are to be cut, the storage area for these nuts being provided on the side of the clamping band and / or cutting device facing the needle beds.

Die gestellte Aufgabe wird erfindungsgemäß auch durch das in Anspruch 18 angegebene Verfahren gelöst.According to the invention, the stated object is also achieved by the method specified in claim 18.

Die genannten Verfahrensschritte können vorzugsweise für mehrere Fäden wiederholt werden, sodaß mehrere Fäden nacheinander mit der einzigen Klemmbandvorrichtung gleichzeitig gehalten werden können, ohne daß für jeden Faden eine eigene Klemmvorrichtung erforderlich ist.The process steps mentioned can preferably be repeated for a plurality of threads, so that a plurality of threads can be held in succession with the single clamping band device, without a separate clamping device being required for each thread.

Vorteilhaft ist es, wenn wenigstens ein geklemmter Faden vom noch zu verarbeitenden Faden abgeschnitten wird, der dann zu einem späteren, vorgegebenen Zeitpunkt wieder zum Stricken benutzt werden soll. Auf diese Weise ist es möglich, Gestricke mit Fäden unterschiedlicher Farbe und/oder Art auf einfache Weise und mit geringem Maschinen- und steuertechnischen Aufwand herzustellen.It is advantageous if at least one clamped thread is cut off from the thread still to be processed, which thread is then to be used again for knitting at a later predetermined time. In this way it is possible to produce knitted fabrics with threads of different colors and / or types in a simple manner and with little expenditure on machinery and control technology.

In Zusammenhang mit dem erfindungsgemäßen Klemmverfahren ist es besonders vorteilhaft, wenn der geklemmte Faden durch Abschneiden des durch die Klemmvorrichtung vom zu verarbeitenden Faden getrennten Fadenbereichs freigegeben wird. Der geklemmte Fadenbereieh wird dann als Fadenrest von der Klemmbandvorrichtung weitertransportiert und fällt am Ende des Klemmbereichs aus der Klemmbandvorrichtung.In connection with the clamping method according to the invention, it is particularly advantageous if the clamped thread is released by cutting off the thread region separated from the thread to be processed by the clamping device. The clamped thread area is then transported as thread remnant by the clamping band device and falls out of the clamping band device at the end of the clamping area.

Die Erfindung wird nachfolgend am Beispiel einer Flachstrickmaschine unter Bezugnahme auf die Zeichnungen erläutert. Es zeigen:

In Figur 1 und 2 ist eine Ausführungsform der erfindungsgemäßen Klemmbandvorrichtung 1 in Zusammenhang mit einer üblichen Flachstrickmaschine 2 schematisch dargestellt, die zwei einander gegenüberliegende dachförmig angeordnete Nadelbetten 3, 4 mit Nadel 5 und Abschlagskämmchen 6 aufweist. Die Flachstrickmaschine ist von üblicher Bauart und daher in diesem Zusammenhange nicht weiter erläuterungsbedürftig.1 and 2 schematically show an embodiment of the clamping band device 1 according to the invention in connection with a conventional flat knitting machine 2 which has two needle beds 3, 4 with a needle 5 and knock-over combs 6 which are arranged opposite one another in a roof shape. The flat knitting machine is of a conventional type and therefore does not require further explanation in this context.

Die Klemmbandvorrichtung 1 ist, wie aus Figur 2 zu ersehen ist, an der Stirnseite der Flachstrickmaschine und hinsichtlich einer durch den Strickbereich vorgegebenen Ebene tiefer als die Nadelbetten 3, 4 (vgl. Figur 1) angeordnet.As can be seen from FIG. 2, the clamping band device 1 is arranged on the front side of the flat knitting machine and, with respect to a plane predetermined by the knitting area, lower than the needle beds 3, 4 (cf. FIG. 1).

Die Klemmbandvorrichtung 1 weist zwei Klemmbänder 7, 8 auf, die an ihren einander zugewandten Außenflächen mit nicht dargestellten Federeinrichtungen aneinander gedrückt, und über Walzen 9, 10 so angetrieben werden, daß die einander berührenden Außenflächen der Klemmbänder im Klemmbereich mit derselben Geschwindigkeit nach unten bewegt werden. Die Drehrichtung der Walzen 9, 10 ist durch Pfeile angedeutet. Die Walzen 9, 10 werden zusammen oder jeweils getrennt durch einem nicht dargestellten Schrittmotor steuerbar gedreht.The clamping band device 1 has two clamping bands 7, 8, which are pressed against one another on their mutually facing outer surfaces with spring devices, not shown, and are driven via rollers 9, 10 such that the contacting outer surfaces of the clamping bands are moved downward in the clamping region at the same speed . The direction of rotation of the rollers 9, 10 is indicated by arrows. The rollers 9, 10 are together or each controllably rotated separately by a stepper motor, not shown.

Wie am besten aus Figur 2 zu ersehen ist, befindet sich seitlich neben der Klemmbandvorrichtung 1 jeweils ein Fadenzuführhaken 11 bzw. 12, die über entsprechende Antriebseinrichtungen 13, 14, beispielsweise mittels eines nicht dargestellten Schrittmotors, gemeinsam oder einzeln nach oben und unten bewegt werden.As can best be seen from FIG. 2, there is a thread feed hook 11 or 12 on each side next to the clamping band device 1, which hooks are moved up or down together or individually via corresponding drive devices 13, 14, for example by means of a stepping motor (not shown).

Die Form des Fadenzuführhakens 11 in seinem oberen Teil ist schematisch aus Figur 1 ersichtlich.The shape of the thread feed hook 11 in its upper part is shown schematically in FIG. 1.

Zwischen der Klemmbandvorrichtung 1 und dem der Flachstrickmaschine 2 benachbarten Fadenzuführhaken 12 ist in schematischer Darstellung eine Schneidvorrichtung 15 in Form einer Schere mit Schneideblättern 16 und 17 dargestellt. Die Schneidvorrichtung 15 ist von herkömmlicher Bauart und kann beispielsweise mittels eines Motors oder eines Magneten steuerbar betätigt werden.Between the clamping belt device 1 and the thread feed hook 12 adjacent to the flat knitting machine 2, a cutting device 15 in the form of a pair of scissors with cutting blades 16 and 17 is shown in a schematic representation. The cutting device 15 is of conventional design and can be actuated in a controllable manner, for example, by means of a motor or a magnet.

Auf einer Seite der Klemmbandvorrichtung 1 ist parallel zu dem in Figur 2 dargestellten vorderen Klemmband 7 ein Fadenablenkelement 18 angeordnet, welches in seinem oberen Teil dreidimensional dreiecks-pyramidenförmig ausgebildet ist. Die Anbringung dieses Fadenablenkelements 18 ist starr.On one side of the clamping band device 1, a thread deflecting element 18 is arranged parallel to the front clamping band 7 shown in FIG. 2, which is three-dimensionally triangular-pyramid-shaped in its upper part. The attachment of this thread deflecting element 18 is rigid.

Auf der den Nadelbetten 3, 4 abgewandten Seite der Klemmbandeinrichtung 1 bzw. des Fadenzuführhakens 11 ist ein Abstellbereich 20 für Nüßchen 21, 22, 23, 24 mit zu klemmenden und/oder zu schneidenden Fäden vorgesehen. Die zu den Nüßchen 21 bis 24 gehörenden Fadenführerkästchen sind der Übersichtlichkeit halber nicht dargestellt.On the side of the clamping band device 1 or the thread feed hook 11 facing away from the needle beds 3, 4 there is a storage area 20 for nuts 21, 22, 23, 24 with threads to be clamped and / or cut. The thread guide boxes belonging to the nuts 21 to 24 are not shown for the sake of clarity.

Auf der dem Nadelbett zugewandten Seite der Kemmbandvorrichtung 1 bzw. des der Strickmaschine 2 benachbarten Fadenzuführhakens 12 ist ein weiterer Abstellbereich 25 für Nüßchen 26, 27 vorgesehen, deren Fäden nicht geklemmt und/oder geschnitten werden sollen.On the side of the clamping band device 1 facing the needle bed or of the thread feed hook 12 adjacent to the knitting machine 2 there is a further storage area 25 for Nut 26, 27 are provided, the threads of which should not be clamped and / or cut.

Die Funktionsweise der erfindungsgemäßen Fadenklemmvorrichtung und damit zusammenwirkender Teile ist folgende:The method of operation of the thread clamping device according to the invention and the parts interacting therewith is as follows:

Es sei bemerkt, daß die letzte Nadel 28 nicht unbedingt die am weitesten außen liegende Nadel auf dem Nadelbett 3 bzw. 4 sein muß; mit dem Begriff "letzte Nadel" ist die zuletzt gestrickte Nadel eines Gestricks gemeint. Nach dem Abstricken der letzten Nadel 28 auf den Nadelbetten 3, 4 wird das Nüßchen 21 bei der Darstellung in Figur 2 von rechts nach links bewegt und im Abstellbereich 20 abgestellt. Der Fadenverlauf zu diesem Zeitpunkt ist in Figur 2 durchgezogen dargestellt.It should be noted that the last needle 28 need not necessarily be the outermost needle on needle bed 3 or 4; the term "last needle" means the last knitted needle of a knitted fabric. After knitting off the last needle 28 on the needle beds 3, 4, the nut 21 is moved from right to left in the illustration in FIG. 2 and placed in the storage area 20. The course of the thread at this time is shown in solid lines in FIG.

Der Faden 29 wird nunmehr bei Absenken der voll nach oben ausgefahrenen Fadenführerhaken 11, 12 von diesen ergriffen und in den Eingangsbereich der Klemmbandvorrichtung 1 gebracht, wie dies am besten aus Figur 1 ersichtlich ist. Dabei gleitet der Faden 29 über das Fadenablenkelelement 18 hinweg und gelangt unter den Vorsprung desselben in einen Bereich unmittelbar zwischen den Klemmbändern 7 und 8. Da die Fadenzuführhaken 11 und 12 den Faden an den Seiten Klemmbandvorrichtung 1 weiter nach unten ziehen, wird ein Zug auf den Faden ausgeübt. Bei einem nachfolgenden Ingangsetzen der Klemmbänder 7 und 8 durch den Schrittmotor wird der Faden 29 daher nach unten bewegt und zwischen die Klemmbänder 7, 8 eingeklemmt. Der Schrittmotor der Klemmbänder 7 und 8 wird nach einer vorgegebene Schrittlänge wieder ausgeschaltet.The thread 29 is now grasped by the thread guide hooks 11, 12 when they are fully extended and brought into the entrance area of the clamping band device 1, as can best be seen in FIG. 1. The thread 29 slides over the thread deflecting element 18 and passes under the protrusion thereof into an area directly between the clamping bands 7 and 8. Since the thread feed hooks 11 and 12 pull the thread further down on the sides of the clamping band device 1, a pull is made on the Thread exercised. When the clamping bands 7 and 8 are subsequently started by the stepping motor, the thread 29 is therefore moved downward and is clamped between the clamping bands 7, 8. The stepping motor of the clamping bands 7 and 8 is switched off again after a predetermined step length.

Insbesondere der der Flachstrickmaschine 2 benachbarte Fadenführerhaken 12 zieht den Faden 29 zuverlässig und sicher soweit nach unten, daß er in die geöffnete Schneidvorrichung 15 gelangt, die danach betätigt wird und den Faden zerschneidet, sodaß das Gestrickende am äußeren Rand des Gestricks frei ist, das andere Fadenende dagegen durch die Klemmwirkung der Klemmbänder 7, 8 gehalten wird.In particular, the flat knitting machine 2 adjacent to the thread guide hook 12 pulls the thread 29 reliably and safely down so far that it gets into the opened cutting device 15, which is then actuated and cuts the thread, so that the end of the knitted is free at the outer edge of the knitted, the other Thread end on the other hand is held by the clamping action of the clamping bands 7, 8.

Wie aus Figur 2 ersichtlich ist, war dieser zuvor geschilderte Ablauf bereits für die Fäden der Nüßchen 22, 23 , 24 vonstatten gegangen. Die Fadenbereiche dieser früher geklemmten und geschnittenen Fäden liegen in der Fadenklemmvorrichtung 1 jeweils untereinander.As can be seen from FIG. 2, this previously described sequence had already been carried out for the threads of the nuts 22, 23, 24. The thread areas of these previously clamped and cut threads lie one below the other in the thread clamping device 1.

Soll nun einer der Fäden, beispielsweise der Faden 30 des Nüßchens 23, wieder von neuem verstrickt werden, wird dieses Nüßchen 23 aus dem Abstellbereich 20 nach rechts über die Nadelbetten 3, 4 bewegt. Da der Faden 30 in der Fadenklemmvorrichtung 1 eingeklemmt ist, wird er über das Fadenablenkelement 18 geführt, welches - wie am besten aus Figur 1 zu ersehen ist - bewirkt, daß der Faden aus dem Klemmbereich der Fadenklemmvorrichtung 1 abgelenkt ist. Der Faden 30 wird danach in der jetzt ersten Nadel 28 des Gestricks verstrickt, sodaß die Verbindung zwischen dem zuvor "geparkten" Faden 30 und dem Gestrick wieder hergestellt ist.If one of the threads, for example the thread 30 of the nut 23, is to be knitted again, this nut 23 is moved from the storage area 20 to the right over the needle beds 3, 4. Since the thread 30 is clamped in the thread clamping device 1, it is guided over the thread deflecting element 18, which - as can best be seen from FIG. 1 - causes the thread to be deflected from the clamping area of the thread clamping device 1. The thread 30 is then knitted in the now first needle 28 of the knitted fabric, so that the connection between the previously "parked" thread 30 and the knitted fabric is restored.

Danach wird der Fadenbereich zwischen der jetzt ersten Nadel 28 des Gestricks und dem in die Fadenklemmvorrichtung 1 eingeklemmten Fadenbereich vom Fadenzuführhaken 12 wieder nach unten in die jetzt wieder offene Schneideinrichtung 15 gezogen und durch Betätigen derselben abgetrennt. Der mit dem Gestrick verbundene Fadenteil ist nunmehr wieder frei und der in der Fadenklemmvorrichtung 1 befindliche Fadenrest wird bei weiteren Fadenklemmvorgängen durch die Bewegung der Fadenklemmbänder 7, 8 nach unten bewegt und fällt schließlich am unteren Ende des Klemmbereichs aus der Fadenklemmvorrichtung 1 heraus.Thereafter, the thread area between the now first needle 28 of the knitted fabric and the thread area clamped in the thread clamping device 1 is pulled down again from the thread feed hook 12 into the cutting device 15, which is now open again, and separated by actuating the same. The thread part connected to the knitted fabric is now free again and the thread residue located in the thread clamping device 1 is moved downward by further movement of the thread clamping bands 7, 8 and finally falls out of the thread clamping device 1 at the lower end of the clamping area.

Die geschilderten Vorgänge wiederholen sich für die jeweiligen unterschiedlichen Fäden, die mit den Fadenführern 21 bis 24 in die "Parkstellung" gebracht wurden.The processes described are repeated for the respective different threads which were brought into the "park position" with the thread guides 21 to 24.

Während bei den herkömmlichen Klemmeinrichtungen mit jeweils für jeden zu klemmenden Faden eigenen Steuer- und Antriebseinrichtungen des Faden zum Klemmen und Freigeben jeweils geöffnet und geschlossen werden muß, sind bei der erfindungsgemäßen Einrichtung bzw. bei dem erfindungsgemäßen verfahren diese Funktionen nicht erforderlich und damit Vorrichtungen hierfür nicht notwendig. Bei der dargestellten Ausführungsform der Erfindung wird der Faden zunächst nach dem "Parken" des Fadenführens abgeschnitten und danach auf einfache Weise wieder dadurch freigegeben, daß derselbe Faden danach nocheinmal nach dem Wiedereinstricken in das Gestrick abgeschnitten wird. Der Restfaden fällt dann früher oder später aus der Fadenklemmeinrichtung heraus. Ein Öffnen und Schließen der Klemmeineinrichtung, wie dies bei herkömmlichen Einrichtungen erforderlich ist, wird dadurch vermieden.While in the conventional clamping devices, each with its own control and drive devices for clamping and releasing each thread to be clamped, it must be opened and closed in the device according to the invention or in the method according to the invention, these functions are not required and therefore devices for this are not necessary. In the illustrated embodiment of the invention, the thread is first cut off after the thread guide has been "parked" and then released again in a simple manner by cutting the same thread again after knitting it into the knitted fabric. The remaining thread will sooner or later fall out of the thread clamping device. This avoids opening and closing of the clamping device, as is required in conventional devices.

Im Bereich 25 sind diejenigen Nüßchen 26, 27 abgestellt, deren Fäden nicht geklemmt und nicht geschnitten werden sollen, beispielsweise deshalb, weil diese Fäden bald wieder für weitere Strickvorgänge verwendet werden, und daher ein Klemmen und Abschneiden nicht erforderlich ist.In the area 25 those nuts 26, 27 are parked, the threads of which should not be clamped and not cut, for example because these threads will soon be used again for further knitting processes and therefore clamping and cutting is not necessary.

Die erfindungsgemäße Fadenklemmvorrichtung 1 sowie das erfindungsgemäße Verfahren zum Klemmen wenigstens eines Fadens in einer Textilmaschine wurde am Beispiel einer Flachstrickmaschine erläutert. Die erfindungsgemäße Fadenklemmvorrichtung sowie das entsprechende Verfahren sind jedoch mit Vorteil grundsätzlich bei allen Textilmaschinen einsetzbar, bei denen einen Fadenklemmung erforderlich oder wünschenswert ist. Die erfindungsgemäße Fadenklemmvorrichtung ist insbesonders dann von Vorteil, wenn mehrere oder gar viele verschiedene Fäden geklemmt und/oder abgeschnitten werden müssen. Dem Fachmann sind dabei Anpassungen der hier beschriebenen Ausführungsform der erfindungsgemäßen Fadenklemmvorrichtung und des erfindungsgemäßen Verfahrens an die jeweiligen Umstände, Textilmaschinen und Gegebenheiten möglich, ohne daß dadurch der Erfindungsgedanke verlassen wird.The thread clamping device 1 according to the invention and the method according to the invention for clamping at least one thread in a textile machine were explained using the example of a flat knitting machine. However, the thread clamping device according to the invention and the corresponding method can advantageously be used in principle in all textile machines in which thread clamping is necessary or desirable. The thread clamping device according to the invention is particularly advantageous when several or even many different threads have to be clamped and / or cut off. The person skilled in the art is adapting the embodiment of the thread clamping device according to the invention and the method according to the invention to the respective circumstances, Textile machines and conditions possible without thereby leaving the inventive idea.
