Description

Die Erfindung betrifft ein Strickschloss einer Flachstrickmaschine mit einem vorlaufenden und einem nachlaufenden Stricksystem.
Außerdem betrifft die Erfindung ein Verfahren zur Herstellung eines Filigrangestricks auf einer Flachstrickmaschine.The invention relates to a knitting lock of a flat knitting machine with a leading and a trailing knitting system.
Moreover, the invention relates to a method for producing a Filigrangestricks on a flat knitting machine.

Um die Mustervielfalt bei gestrickten Textilien zu erweitern, wurde bereits vorgeschlagen, so genannte Durchbruchmuster in Gestricken herzustellen, wobei Maschen oder Maschengruppen so umgehängt werden, dass Öffnungen in vorbestimmten Bereichen im Gestrick entstehen. Nachteilig ist hier, dass durch die Umhängeprozesse weniger Maschenkapazität zur Maschenherstellung genutzt werden kann. Weiterhin verliert der Bereich des Gestricks, in welchem Maschen umgehängt werden, an Stabilität.In order to expand the variety of patterns in knitted textiles, it has already been proposed to produce so-called breakthrough patterns in knitted fabrics, with stitches or mesh groups being transferred in such a way that openings occur in predetermined areas in the knitted fabric. The disadvantage here is that less mesh capacity can be used for mesh production by the Umhängeprozesse. Furthermore, the area of the knitted fabric in which stitches are transferred loses stability.

In der DE 23 63 161 A1 ist das Prinzip der Maschenbildung in Filigrantechnik beschrieben, wobei ein verzugsfreies Gestrick hergestellt wurde. Hierzu wird ein Basisgestrick mit einem Bindefaden hergestellt, der für das menschliche Auge fast nicht sichtbar ist. Das eigentliche Muster wird mit einem Musterfaden gebildet, wobei an den Stellen, an denen das Muster auftreten soll, Maschen sowohl mit dem Musterfaden als auch mit dem Bindefaden gebildet werden.In the DE 23 63 161 A1 the principle of stitch formation in filigree technique is described, whereby a draft-free knit fabric was produced. For this purpose, a base knit is made with a binder thread, which is almost invisible to the human eye. The actual pattern is formed with a pattern thread, where in the places where the Pattern should be formed, stitches are formed both with the pattern thread and with the binding thread.

Bei älteren Schlosssystemen von Flachstrickmaschinen war es möglich, Gestricke in Filigrantechnik auszubilden, da die im jeweils nachlaufenden Stricksystem nicht ausgewählten Nadeln trotzdem kuliert wurden. In modernen Strickschlössern von Flachstrickmaschinen ist es bisher nicht möglich, Gestricke in Filigrantechnik herzustellen, da im jeweils nachlaufenden Stricksystem nicht ausgewählte Nadeln nicht kuliert werden können.In older lock systems of flat knitting machines, it was possible to form knitted fabrics in filigree technique, since the needles not selected in the respective trailing knitting system were nevertheless calculated. In modern knitting locks of flat knitting machines, it has hitherto not been possible to produce knitted fabrics using filigree technology, since non-selected needles can not be emulated in the respective trailing knitting system.

In der FR 756.318 ist beschrieben, wie mit einer Rundstrickmaschine, welche gesteuerte Schlossteile besitzt, ein Filigrangestrick hergestellt wird. Dies geschieht, indem Nadeln, welche zusätzlich zum Bindefaden einen Musterfaden erhalten sollen, weiter ausgetrieben werden als die Nadeln, in welche nur der Bindefaden eingelegt werden soll.In the FR 756,318 is described how a circular knitting machine, which has controlled lock parts, a Filigrangestrick is produced. This is done by needles, which are to receive a pattern thread in addition to the binding thread, be further expelled as the needles, in which only the binding thread to be inserted.

Die EP 0 896 078 A2 offenbart eine Flachstrickmaschine mit Schiebernadeln sowie ein Strickschloss zum Betreiben dieser Schiebernadeln mit den Funktionen "Nichtstricken", "Fang", "Masche" und "Übergabe-Übernahme". Es ist ein vorlaufendes und ein nachlaufendes Strickschloss vorgesehen. Alle Nadeln, welche im vorlaufenden Schloss am Strickprozess teilgenommen haben, werden durch innere Abzugsschlossteile wieder komplett zurückgezogen und auf Kammgleiche gebracht, ehe sie im nachlaufenden Strickschloss wieder ausgetrieben werden.The EP 0 896 078 A2 discloses a flat knitting machine with slider needles and a knitting lock for operating these needles with the functions "non-knitting", "catch", "stitch" and "transfer takeover". There is a leading and a trailing knitting lock provided. All needles, which have participated in the leading lock on the knitting process, are completely withdrawn by inner Abzugsschlossteile and brought to the same point before they are expelled again in the trailing knot lock.

Die US 6,308,538 B1 offenbart ein Verfahren zur Herstellung von fusselfreien Tüchern auf einer zweisystemigen Flachstrickmaschine. Die Maschine ist mit Hoch- und Niederfußnadeln sowie entsprechend schaltbaren Schlossteilen ausgestattet. Das Gestrick wird hergestellt unter Verwendung der Strickarten "Masche", "Fang", "Nichtstricken", welche in unterschiedlicher Weise auf dem vorderen und hinteren Nadelbett kombiniert werden.The US 6,308,538 B1 discloses a method of producing lint-free wipes on a two-system flat knitting machine. The machine is equipped with high and low foot needles as well equipped switchable lock parts. The knit is made using the knits "stitch", "catch", "no knit", which are combined in different ways on the front and back needle bed.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zur Herstellung eines Filigrangestricks auf einer Flachstrickmaschine mit einem modernen Strickschloss sowie ein entsprechendes Strickschloss bereitzustellen, mit dem ein Filigrangestrick hergestellt werden kann.Object of the present invention is to provide a method for producing a Filigrangestricks on a flat knitting machine with a modern knitting lock and a corresponding knitting lock with which a Filigrangestrick can be produced.

Gelöst wird diese Aufgabe durch ein Strickschloss einer Flachstrickmaschine mit den Merkmalen des Anspruchs 1.This problem is solved by a knitting lock of a flat knitting machine having the features of claim 1.

Mit einem solchen Strickschloss ist es möglich, ein Filigrangestrick herzustellen. Die Nadeln, die keinen Musterfaden erhalten, aber einen Bindefaden erhalten haben, werden in ihrer Position gehalten oder nur unwesentlich ausgetrieben, solange die übrigen Nadeln den Musterfaden erhalten. Es wird sichergestellt, dass die dritte Anzahl von Nadeln im nachlaufenden Stricksystem nicht an einem Strickprozess teilnehmen, wobei im Sinne der Erfindung bereits das Umhängen von Maschen als Strickprozess betrachtet wird. Insbesondere wird sichergestellt, dass mit der dritten Anzahl von Nadeln kein Umhängevorgang durchgeführt wird und keine Masche gebildet wird.With such a knitting lock, it is possible to produce a filigree knit. The needles, which have not received a pattern thread but have received a binding thread, are held in position or driven out only insignificantly, as long as the remaining needles receive the pattern thread. It is ensured that the third number of needles in the trailing knitting system does not take part in a knitting process, whereby in the sense of the invention the knitting of stitches is already considered as a knitting process. In particular, it is ensured that no transfer operation is carried out with the third number of needles and no stitch is formed.

Besondere Vorteile ergeben sich, wenn das Strickschloss bezüglich einer Mittenebene symmetrisch aufgebaut ist. Dies bedeutet, dass eine Maschenbildung in beiden Schlittenrichtungen durchgeführt werden kann.Particular advantages arise when the knitting lock is constructed symmetrically with respect to a central plane. This means that stitching can be performed in both carriage directions.

Die zweite Anzahl von Nadeln kann geringer sein als die erste Anzahl von Nadeln. Weiterhin ist es denkbar, dass mit allen ausgewählten Nadeln auch der Musterfaden gestrickt wird. Dies bedeutet, dass die zweite Anzahl von Nadeln der ersten Anzahl von Nadeln entsprechen kann.The second number of needles may be less than the first number of needles. Furthermore, it is conceivable that with all the selected needles and the pattern thread is knitted. This means that the second number of needles may correspond to the first number of needles.

Zwischen den Stricksystemen ist ein Brückenteil angeordnet, welches die erste Anzahl von Nadeln nach der Einlage eines Bindefadens zunächst auf einer Fadeneinlageposition hält und dann auf eine Position oberhalb der Kammgleiche abzieht. Insbesondere werden die Nadeln im Bereich kurz vor der Schlossmitte auf eine Position oberhalb der Kammgleiche abgezogen. So wird erreicht, dass der Bindefaden in die Nadelhaken eingelegt wird, die Nadeln aber nur so weit abgezogen werden, dass die "alte" Masche, welche sich auf dem Nadelschaft befindet, zwar die Zunge schließt, aber nicht abgeschlagen wird (Fang auf der Nadel). Im nachlaufenden Stricksystem werden die Nadeln, welche mustergemäß zusätzlich zum Bindefaden einen Musterfaden erhalten sollen, ausgewählt und mittels eines Austriebsmittels auf eine Höhe zur Fadeneinlage (Fang oder Stricken) ausgetrieben, wodurch eine erneute Fadeneinlage (des Musterfadens) erfolgen kann. Der Austrieb der zweiten Anzahl von Nadeln im nachlaufenden Stricksystem erfolgt vorzugsweise durch ein Austriebsschlossteil. Das Austriebsmittel des vorlaufenden Stricksystems kann beispielsweise ein Austriebsschlossteil sein.Between the knitting systems, a bridge part is arranged, which first holds the first number of needles after the insertion of a binding thread on a thread insertion position and then subtracts to a position above the comb equal. In particular, the needles are withdrawn in the area just before the middle of the castle to a position above the comb equal. This ensures that the binding thread is inserted into the needle hooks, but the needles are removed only so far that the "old" stitch, which is located on the needle shaft, although the tongue closes, but is not knocked off (catch on the needle ). In the trailing knitting system, the needles, which according to the pattern should receive a pattern thread in addition to the binding thread, are selected and expelled by means of a flushing means to a height to the thread insert (catch or knitting), whereby a renewed thread insert (the pattern thread) can take place. The expulsion of the second number of needles in the trailing knitting system is preferably carried out by a Austriebsschlossteil. The ejection means of the leading knitting system may be, for example, a Austriebsschlossteil.

Gemäß einer Ausführungsform kann eine Führung zur Führung der Füße der dritten Anzahl von Nadeln vorgesehen sein. Die Führung ist vorzugsweise im Austriebsschlossteil des nachlaufenden Stricksystems ausgebildet. Insbesondere kann die Führung als Nut ausgebildet sein.According to one embodiment, a guide for guiding the feet of the third number of needles may be provided. The guide is preferably formed in the Austriebsschlossteil the trailing knitting system. In particular, the guide may be formed as a groove.

Durch die zweiten Auswahlmittel zur Auswahl der Nadeln, die nicht Bestandteil der zweiten Nadeln sind, kann sichergestellt werden, dass die Füße dieser Nadeln in die Führung gelangen und nicht so weit ausgetrieben werden wie die zweite Anzahl von Nadeln. Es können auch zweite Austriebsmittel vorgesehen sein, die die Nadeln, die nicht zur zweiten Anzahl der Nadeln gehören, ein Stück weit (nicht so weit wie die zweite Anzahl von Nadeln) austreiben. Allerdings werden diese Nadeln allenfalls so weit ausgetrieben, dass sie nicht an einem Strickprozess im nachlaufenden Stricksystem teilnehmen.By the second selection means for selecting the needles, which are not part of the second needles, it can be ensured that the feet of these needles get into the guide and are not expelled as far as the second number of needles. It is also possible to provide second ejection means which expel the needles which do not belong to the second number of needles a little way (not as far as the second number of needles). However, these needles are at most driven out so far that they do not participate in a knitting process in the trailing knitting system.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass das nachlaufende Stricksystem ein Drückerteil zum Unterdrücken der Füße der Nadeln der ersten Anzahl von Nadeln, die nicht Bestandteil der zweiten Anzahl von Nadeln sind, oder von zugeordneten Kupplungsteilen für die Strickauswahl aufweist. Das Drückerteil sorgt dafür, dass die Füße dieser Nadeln in die Führung des nachlaufenden Stricksystems gelangen. Insbesondere können Füße von Kupplungsteilen beim Einlaufen in das nachlaufende Stricksystem unterdrückt werden und erst wieder freigegeben werden, wenn sich die Nadelfüße der im nachlaufenden Stricksystem nicht für eine Maschenbildung mit dem Musterfaden ausgetriebenen Nadeln der ersten Anzahl von Nadeln in der Führung befinden.According to an advantageous embodiment of the invention can be provided that the trailing knitting system comprises a pusher member for suppressing the feet of the needles of the first number of needles, which are not part of the second number of needles, or of associated coupling parts for knitting selection. The pusher part ensures that the feet of these needles get into the guidance of the trailing knitting system. In particular, feet of coupling parts can be suppressed when entering the trailing knitting system and only released again when the needle feet are not driven in the trailing knitting system for stitching with the pattern thread needles of the first number of needles in the guide.

Vorteilhafterweise weist das vorlaufende Stricksystem ein innen liegendes Abzugsschlossteil auf, welches außer Funktion gesetzt ist. Dadurch wird sichergestellt, dass die erste Anzahl von Nadeln lediglich bis auf eine Position oberhalb der Kammgleiche und nicht weiter abgezogen wird.Advantageously, the leading knitting system has an internal deduction lock part, which is disabled. This will ensure that the first number of needles will only be pulled off to one position above the comb and not further.

In den Rahmen der Erfindung fällt außerdem eine Flachstrickmaschine mit einem erfindungsgemäßen Strickschloss.The scope of the invention also includes a flat knitting machine with a knitting lock according to the invention.

In den Rahmen der Erfindung fällt außerdem ein Verfahren zur Herstellung eines Filigrangestricks auf einer Flachstrickmaschine mit den Merkmalen des Anspruchs 7.The scope of the invention also includes a method for producing a filigree knit on a flat knitting machine having the features of claim 7.

Zur Herstellung eines Gestrickstücks in Filigrantechnik gemäß dem erfindungsgemäßen Verfahren wird zunächst im jeweils vorlaufenden Stricksystem ein relativ dünner Bindefaden eingelegt (Fang). Der vorhandene Faden (Masche) wird aber nicht abgeschlagen. Er bleibt auf der Zunge liegen (aufgelegter Fang). Im jeweils nachlaufenden Stricksystem wird der Musterfaden in ausgewählte und ausgetriebene Nadeln eingelegt. Anschließend werden die Nadeln kuliert, wodurch die Nadeln, in welche einer der Fäden oder beide Fäden eingelegt sind, Maschen ausbilden. Mit dem erfindungsgemäßen Verfahren können Filigrangestrick und Plüsch einzeln oder in Kombination hergestellt werden. Es können ein- oder zweibettige Flachstrickmaschinen mit Zungen- oder Schiebernadeln verwendet werden. Das Basisgestrick, welches mit dem Bindefaden gebildet wird, kann mit allen Nadeln oder unter teilweiser Verwendung der Nadeln (multigauge, flexible gauge) gebildet werden. Die erste Anzahl von Nadeln, die einen Faden erhalten, kann also allen Nadeln der Flachstrickmaschine oder nur einem Teil davon entsprechen. Die zweite Anzahl von Nadeln, die einen Faden erhalten, kann der ersten Anzahl von Nadeln oder einem Teil davon entsprechen.To produce a knitted piece in filigree technique according to the method according to the invention, a relatively thin binding thread is first inserted in the respectively preceding knitting system (catch). The existing thread (stitch) is not knocked off. He stays on the tongue (put on catch). In each trailing knitting system, the pattern thread is inserted into selected and expelled needles. Subsequently, the needles are emulated, whereby the needles, in which one of the threads or both threads are inserted, form stitches. Filigrangestrick and plush can be produced individually or in combination with the inventive method. One or two-bed flat knitting machines with reed or slider needles can be used. The basic knit, which is formed with the binding thread, can be formed with all needles or with the partial use of the needles (multigauge, flexible gauge). The first number of needles that receive a thread can thus correspond to all needles of the flat knitting machine or only a part thereof. The second number of needles that receive a thread may correspond to the first number of needles or a part thereof.

Diejenigen Nadeln, die einen Bindefaden erhalten haben, jedoch nicht auch einen Musterfaden erhalten sollen, werden vorzugsweise zumindest im Wesentlichen in ihrer Position, insbesondere oberhalb der Kammgleiche, gehalten, während bei den übrigen Nadeln (zweite Anzahl der Nadeln) der Musterfaden eingelegt wird. Anschließend können dann alle Nadeln, die am Strickprozess beteiligt waren, d. h. die erste Anzahl von Nadeln, kuliert werden.Those needles which have received a binding thread, but are not also to receive a pattern thread, are preferably held at least essentially in their position, in particular above the comb, while the other needles (second number of needles) are loaded with the pattern thread. Then you can then all needles that were involved in the knitting process, ie the first number of needles, are being recalculated.

Die erste Anzahl von Nadeln wird vor der Auswahl der zweiten Anzahl von Nadeln auf eine Position oberhalb der Kammgleiche abgezogen. Die mit dem vorlaufenden Stricksystem ausgewählten Nadeln (erste Anzahl von Nadeln) werden ausgetrieben und der dünne Bindefaden wird in die Nadelhaken der ausgewählten Nadeln eingelegt. Anschließend werden die Nadeln aber nicht auf Kuliertiefe abgezogen. Hierfür können innen liegende, eventuell im Strickschloss vorhandene Abzugsschlossteile außer Funktion gesetzt werden. Somit bleibt die Möglichkeit erhalten, in die ausgewählten Nadeln nochmals einen Faden, insbesondere einen Musterfaden, einzulegen.The first number of needles is withdrawn to a position above the combing equal before selecting the second number of needles. The needles selected with the leading knitting system (first number of needles) are expelled and the thin binding thread is inserted into the needle hooks of the selected needles. Subsequently, however, the needles are not subtracted to the depth of the carton. For this purpose, inside lying, possibly existing in the knitting lock deduction lock parts are disabled. Thus, the possibility remains in the selected needles again insert a thread, in particular a pattern thread.

Gemäß einer Verfahrensvariante können die Füße der dritten Anzahl von Nadeln in einer Führung des nachlaufenden Stricksystems geführt werden, während die zweite Anzahl von Nadeln zur Maschenbildung mit dem Musterfaden ausgetrieben ist.According to a variant of the method, the feet of the third number of needles can be guided in a guide of the trailing knitting system, while the second number of needles for stitching with the pattern thread is expelled.

The basic knit G can be in the form of a ribbed knit, plain knit or other knitwear, depending on the area in which the knitted fabric is to be used. For better illustration, only a single row of filigree stitches is shown here.

Die dargestellte Maschenreihe in Filigrantechnik wird ebenso wie die darauf folgenden Maschenreihen in dieser Technik mittels eines Bindefadens B sowie eines Musterfadens M hergestellt. Der gezeigte Ausschnitt der Maschenreihe weist die Maschen 1 bis 7 auf. Es ist zu erkennen, dass die Maschen 1 und 2 sowohl aus dem Bindefaden B als auch aus dem Musterfaden M hergestellt sind. Die Masche 3 weist nur den Bindefaden B auf. Der Musterfaden M verläuft als Flottfaden über deren Schenkel. Die Masche 4 wurde wiederum sowohl aus dem Bindefaden B als auch aus dem Musterfaden M gebildet. Die Masche 5 besteht wiederum nur aus dem Bindefaden B. Der Musterfaden M verläuft wieder als Flottfaden über deren Schenkel. Die beiden Maschen 6 und 7 sind sowohl aus dem Bindefaden B als auch aus dem Musterfaden M gebildet. Durch die Kombination der beschriebenen Möglichkeiten zur Fadeneinlage in der Gestrickbreite als auch in der Höhe des Gestricks lassen sich Muster in Filigrantechnik erzeugen. Durch die Verwendung sowohl eines Bindefadens B als auch eines Musterfadens M lässt sich ein gleichmäßiges, verzugfreies Gestrick herstellen, wobei der dünne Bindefaden B das Gerüst, d. h. ein Basisgestrick, bildet, welches dem Gestrick die gewünschte Stabilität gibt. Der Musterfaden M, welcher dicker, dünner, andersfarbig usw. als der Bindefaden B sein kann, bildet die sichtbare Struktur des Gestrickmusters aus.The illustrated series of filigree stitches as well as the subsequent courses are produced in this technique by means of a binding thread B and a pattern thread M. The section of the stitch row shown has the stitches 1 to 7. It can be seen that the stitches 1 and 2 are made of both the binding thread B and the pattern thread M. The stitch 3 has only the binding thread B. The pattern thread M runs as a floss thread over the legs. Again, the loop 4 was formed from both the binder thread B and the pattern thread M. The stitch 5 in turn consists only of the binding thread B. The pattern thread M runs again as a float thread over the legs. The two stitches 6 and 7 are formed both from the binding thread B and from the pattern thread M. By The combination of the possibilities described for inserting the thread in the knit width as well as in the height of the knit can be used to create patterns using filigree technology. By using both a binding thread B and a pattern thread M, a uniform, warp-free fabric can be produced, wherein the thin binding thread B, the framework, ie a base knit, forms, which gives the knit the desired stability. The pattern thread M, which may be thicker, thinner, different colored, etc., than the binding thread B, forms the visible structure of the knit pattern.

Die Fig. 2 zeigt ein modernes zweisystemiges Strickschloss 100, welches für die Herstellung von Gestrickstücken in Filigrantechnik geeignet ist. Die Bewegung des Strickschlosses 100 erfolgt im gezeigten Beispiel in Richtung des Pfeils SL. Auf diese Bewegungsrichtung beziehen sich auch die Bezeichnungen "vorlaufendes und nachlaufendes Stricksystem", da das Strickschloss 100 symmetrisch aufgebaut ist und die Maschenbildung in beiden Schlittenrichtungen durchgeführt werden kann.The Fig. 2 shows a modern two-system knitting lock 100, which is suitable for the production of knitted pieces in filigree technology. The movement of the knitting cam 100 takes place in the example shown in the direction of the arrow SL. In this direction of movement, the terms "leading and trailing knitting system", since the knitting cam 100 is constructed symmetrically and the stitch formation can be performed in both carriage directions.

Eine erste Anzahl Nadeln N1 werden mittels eines Auswahlmittels ausgewählt und mittels eines Austriebsmittels in Form eines Austriebsschlossteils 10a oder in Form eines Abzugsschlossteils 12a ausgetrieben. Der Bindefaden B wird in die Nadelhaken der ausgewählten Nadeln N1 eingelegt. Die Nadeln N1 werden anschließend durch die Kurve 50 nicht auf Kuliertiefe abgezogen. Um ein Abziehen auf Kuliertiefe zu verhindern, wurden innenliegende Abzugsschlossteile außer Funktion gesetzt bzw. entfernt.A first number of needles N 1 are selected by means of a selection means and expelled by means of an expulsion means in the form of an expulsion lock part 10a or in the form of a deduction lock part 12a. The binding thread B is inserted into the needle hooks of the selected needles N 1 . The needles N 1 are then not subtracted by the curve 50 to the depth of the Kuft. In order to prevent removal to the depth of the chucking, internal trigger lock parts were deactivated or removed.

Zwischen den beiden Stricksystemen S1, S2 ist ein Brückenteil 30 eingesetzt, welches über die Führung 51 die Nadeln N1 zunächst auf einer Fadeneinlageposition hält und im Bereich kurz vor der Schlossmitte SM durch die Kurve 52 auf eine Position 53 oberhalb der Kammgleiche abzieht. So wird erreicht, dass zwar der Bindefaden B in die Nadelhaken eingelegt wird, die Nadeln N1 aber nur so weit abgezogen werden, dass die alte Masche, welche sich auf dem Nadelschaft befindet, zwar die Zunge schließt, aber nicht abgeschlagen wird.Between the two knitting systems S1, S2, a bridge member 30 is inserted, which initially holds the needles N 1 via the guide 51 on a thread insertion position and subtracts in the area just before the middle of the castle SM through the curve 52 to a position 53 above the comb. This ensures that although the binding thread B is inserted into the needle hook, the needles N 1 but only so far deducted that the old mesh, which is located on the needle shaft, although the tongue closes, but is not knocked off.

Im nachlaufenden System S2 werden die Nadeln N2, welche mustermäßig zusätzlich zum Bindefaden einen Musterfaden M erhalten sollen, als eine zweite Anzahl von Nadeln N2, mittels eines ersten Auswahlmittels ausgewählt und mittels des Austriebsschlossteils 10b auf eine Höhe zur Fadeneinlage ausgetrieben, wodurch eine erneute Fadeneinlage mit dem Musterfaden M erfolgt.In the trailing system S2, the needles N 2 , which are to receive a pattern thread M in pattern addition to the binding thread, selected as a second number of needles N 2 , by means of a first selection means and expelled by the Austriebsschlossteils 10 b at a height to the thread insert, creating a renewed Thread insert with the pattern thread M takes place.

Die Nadeln der ersten Anzahl von Nadeln N1, die nicht auch Bestandteil der zweiten Anzahl von Nadeln N2 sind, also diejenigen Nadeln N3, die lediglich einen Bindefaden B erhalten, nicht jedoch den Musterfaden M, werden durch ein zweites Auswahlmittel ausgewählt und in ihrer vorhergehenden Austriebshöhe belassen. Sie durchlaufen mit ihren Füßen eine Führung 11b im Austriebsschlossteil 10b. Das Drückerteil 13b unterdrückt die hier nicht dargestellten Füße von Kupplungsteilen (Strickauswahl) beim Einlaufen in das nachlaufende Stricksystem S2. Die Füße werden erst freigegeben, wenn sich die Nadelfüße der im zweiten Stricksystem S2 nicht für die Fadeneinlage ausgewählten Nadeln N3 der ersten Anzahl von Nadeln N1 in der Führung 11b befinden. Daran anschließend werden alle Nadeln, d. h. die erste Anzahl von Nadeln N1, durch das nachlaufende Abzugsschlossteil 12b in Kuliertiefe abgezogen, wodurch alle Nadeln N1 ihre Maschen ausbilden.The needles of the first number of needles N 1 , which are not also part of the second number of needles N 2 , ie those needles N 3 , which receive only a binding thread B, but not the pattern thread M are selected by a second selection means and in leave their previous shoot height. They go through with their feet a guide 11b in the Austriebsschlossteil 10b. The pusher part 13b suppresses the not shown feet of coupling parts (knit selection) when entering the trailing knitting system S2. The feet are not released until the needle feet of the needles N 3 of the first number of needles N 1 in the guide 11 b that are not selected for the thread insert in the second knitting system S2 are located. Subsequently, all needles, ie the first number of needles N 1 , are deducted by the trailing Abzugsschlossteil 12 b in Kuliertiefe, whereby all needles N 1 form their stitches.

Der Fig. 2 ist zu entnehmen, dass bei einer Bewegungsrichtung entgegen des Pfeils SL der Nadelsenker 12a als Abzugsschlossteil zum Kulieren aller Nadeln wirkt. Entsprechend kommen bei einer Bewegungsrichtung entgegen der Pfeilrichtung SL das innere Drückerteil 13a und die Führung 11a zum Einsatz, da dann das Stricksystem S1 das nachlaufende Stricksystem ist.Of the Fig. 2 It can be seen that in a direction of movement opposite to the arrow SL of the needle counter 12a acts as Abzugsschlossteil for Kulieren all needles. Correspondingly, in a direction of movement opposite to the direction of the arrow SL, the inner pusher part 13a and the guide 11a are used, since then the knitting system S1 is the trailing knitting system.

Das Brückenteil 30 ist symmetrisch zur Schlossmitte SM angeordnet und ragt in beide Stricksysteme S1, S2. Die Schlossmitte SM stellt eine Symmetrieebene dar.The bridge part 30 is arranged symmetrically to the middle of the lock SM and projects into both knitting systems S1, S2. The lock center SM represents a symmetry plane.
