Description

Die Erfindung betrifft ein laufmaschengehemmtes Polschlingengewirke sowie ein Verfahren und eine Maschine zu seiner Herstellung, die bei der Produktion von Textilien mit ein- und zweiseitiger Polschlingenoberfläche eingesetzt werden.The invention relates to a knitted pile loop knitted fabric as well as a method and a machine for its manufacture, which are used in the production of textiles with a one- and two-sided pile loop surface.

Bekannt ist ein Polschlingengewirke mit einem ein-und zweiseitigen Liropol-Schlingenpol, das aus einem Warengrund bzw. einer Grundware besteht, die von den Maschenstäben von in Fransebindung gelegten Bindekettfäden und einem Schlussfadensystem, die zwischen Nadel- und Platinenmasche der Franse über vier Maschenstäbchen eingebunden sind, sowie von einem hinteren und vorderen Polfaden gebildet wird, die jeweils zwischen Nadel- und Platinenmasche der Franse zwischen zwei benachbarten Stäbchen abgebunden sind (Vliessstoffe, Verlag Technika, 1980).Known is a pile loop knitted fabric with a one-sided and two-sided liropole loop pile, which consists of a fabric base or a basic fabric, which consists of the wales of binding warp threads laid in fringe binding and a closing thread system which are integrated between the needle and sinker stitches of the fringe via four wales , and is formed by a back and front pile thread, each of which is tied between the needle and sinker stitch of the fringe between two adjacent rods (Vliessstoffe, Verlag Technika, 1980).

Nachteilig bei dem Liropol-Gewirke sind eine Trennung des Warengrundes, hervorgerufen durch die Fransebindung, ein begrenztes Struktursortiment des Gewirkes, eine ungenügende Festigkeit des Schlingenpols beim Ziehen der vorderen Polfäden und ungenügende hygienische Eigenschaften des Gewirkes aufgrund der zwangsläufigen Anwendung von Endlosfäden als Wirkfäden.Disadvantages of the Liropol knitted fabric are a separation of the fabric base, caused by the fringe binding, a limited structural range of the knitted fabric, insufficient strength of the loop pile when pulling the front pile threads and insufficient hygienic properties of the knitted fabric due to the inevitable use of continuous threads as knitting threads.

Bei dem Verfahren zur Herstellung des Liropol-Gewirkes durchlaufen die Wirknadeln von einer hinteren Endstellung nacheinander eine Zone für die Legung von hinteren Polfäden, eine Zone für das Drükken der hinteren Polfäden und ein Schussfadensystem, eine Zone für die Legung von einem Schussfadensystem, und eine Zone für die Legung der vorderen Polfäden und erreichen eine vordere Endstellung für die Legung von Strickfäden. Die vorderen Polfäden werden nicht gewirkt, sondern mit den Wirkfäden durch die Platinen- und Nadelmaschen der Franse abgebunden, wobei die Legung des einen Schussfadensystems und der hinteren Polfäden über den Wirknadeln und der Abzug unter die Wirknadeln durch eine spezielle Druckplatine erfolgt.In the process for producing the Liropol knitted fabric, the knitting needles successively pass from a rear end position to a zone for laying back pile threads, a zone for pressing the rear pile threads and a weft thread system, a zone for laying a weft thread system, and a zone for the laying of the front pile threads and reach a front end position for the laying of knitting threads. The front pile threads are not knitted, but are tied with the knit threads through the plate and needle stitches of the fringe, with the laying of the one weft thread system and the rear pile threads over the knitting needles and the withdrawal under the knitting needles using a special printing plate.

Bei diesem Verfahren muss ein Druck der gelegten hinteren Polfäden auf den Wirknadeln und dem Schussfadensystem ausgeübt werden. Das Verfahren erlaubt lediglich eine gleichlegige Legung des Schussfadensystems in einer Maschenreihe, was die Erzielung verschiedenartiger Strukturgewirke einschränkt. Ferner gewährleistet die Abbindung der vorderen Polfäden durch die Platinen- und Nadelmaschen in der Franse keine stabile Bindung der Polfäden mit dem Warengrund.With this procedure, pressure must be exerted on the rear pile threads placed on the knitting needles and the weft thread system. The method only allows the weft thread system to be laid in the same row in a stitch row, which limits the achievement of different types of structural knits. Furthermore, the binding of the front pile threads through the sinker and needle stitches in the fringe does not guarantee a stable bond between the pile threads and the fabric base.

Die zur Herstellung von Liropol-Gewirken mit ein-und zweiseitigem Schlingenpol verwendete Maschine besteht aus Wirknadeln mit einem Schlitz, die senkrecht zur Ebene der vorderen und hinteren Polplatinen verlaufen. Zwischen den Wirknadeln sind Schiebernadeln vorgesehen. Hinter den hinteren Polplatinen sind spezielle Druckplatinen und Lochnadeln für die hintere Schlingenoberfläche angeordnet. Vor den vorderen Polplatinen sind Lochnadeln für die vordere Poloberfläche und Lochnadeln für die Wirkfäden angeordnet. Bei der Liropol-Maschine müssen Nadeln mit einem Schlitz verwendet werden, was eine grosse Spannung der Wirkfäden erfordert, wodurch die Fadenbruchhäufigkeit und die Fehler im Gewirke erhöht werden, es sei denn, man benutze feste und elastische Endlosfäden als Wirkfäden. Da spezielle Druckplatinen erforderlich sind, ist der Aufbau der Maschine kompliziert. Das Vorhandensein von lediglich einem System von Schieberschussnadeln schränkt die Sortimentsmöglichkeiten für Gewirke mit verschiedenartigen Strukturen ein. Die Anordnung der Lochnadeln auf den vorderen Polfäden erlaubt lediglich die Legung, aber nicht das Wirken.The machine used to produce Liropol knitted fabrics with one-sided and two-sided loop pile consists of knitting needles with a slot that run perpendicular to the plane of the front and rear pile boards. Slider needles are provided between the knitting needles. Special pressure plates and perforated needles for the rear loop surface are arranged behind the rear pole plates. In front of the front pile sinkers, perforated needles for the front pile surface and perforated needles for the knitting threads are arranged. With the Liropol machine, needles with a slit must be used, which requires a high tension of the knitting threads, which increases the frequency of thread breaks and the errors in the knitted fabric, unless one uses solid and elastic continuous threads as knitting threads. Since special printing boards are required, the construction of the machine is complicated. The presence of only one system of sliding weft needles limits the range of options for knitted fabrics with different structures. The arrangement of the perforated needles on the front pile threads allows only the laying, but not the knitting.

Zum Stand der Technik gehört weiterhin ein maschenlaufgehemmtes Polschlingengewirke, bei dem die Struktur des Liropol-Gewirkes vervollkommnet ist. Die normal offenen vorderen Polschlingen werden von den vorderen Polfäden des Liropol-Gewirkes gebildet und sind mindestens im überwiegenden Teil derjenigen Maschenreihe gebunden, in denen sie gleichlegig mit den Wirkfäden zwischen den Nadel-und Platinenmaschen gelegt sind, wobei die in sämtlichen Maschen gebildeten offenen Schlaufen auf die rechte Seite der Ware durchgezogen sind (DD-B-134789).The state of the art also includes a loop-loop-knitted pile loop knitted fabric in which the structure of the Liropol knitted fabric is perfected. The normally open front pile loops are formed by the front pile threads of the Liropol knitted fabric and are tied at least in the predominant part of the row of stitches in which they are placed in line with the knit threads between the needle and sinker stitches, the open loops formed in all stitches being open the right side of the goods are pulled through (DD-B-134789).

Es ergeben sich die gleichen Nachteile wie beim Liropol-Gewirke, wobei Maschenfestigkeit und Durchziehen der vorderen Polfäden teilweise verbessert sind, was sich jedoch einschränkend auf die Sortimentsmöglichkeiten auswirkt.The same disadvantages as with the Liropol knitted fabric result, whereby the stitch strength and pulling through of the front pile threads are improved in some cases, but this has a restrictive effect on the range options.

Bei der Herstellung dieses maschenlaufgehemmten Polschlingengewirkes werden im Gegensatz zur Herstellung des Liropol-Gewirkes die vorderen Polfäden den Häkelnadeln in jeder zweiten Maschenreihe gleichlegig zu den Bindekettfäden vorgelegt und dadurch am Schaft jeder Nadel geklemmt. Beim Rückzug wird die Klemmung aufrechterhalten, wobei je eine offene Schlaufe aus Polfadenmaterial aus einer Fadenreserve gebildet wird, die beim Pressen der durch die Wirknadeln gebildeten Masche erzielt wird. Verglichen mit der Herstellung des Liropol-Gewirkes lässt sich lediglich die Maschenfestigkeit der Hälfte der Polreihen verbessern.In contrast to the production of the Liropol knitted fabric, the front pile threads are presented to the crochet hooks in every second row of stitches equally to the binding warp threads and thus clamped on the shaft of each needle. When retracting, the clamping is maintained, an open loop made of pile thread material being formed from a thread reserve, which is achieved when the stitch formed by the knitting needles is pressed. Compared to the manufacture of the Liropol knitted fabric, only the mesh strength of half of the pile rows can be improved.

Die Maschine zur Herstellung von maschenlaufgehemmten Polschlingengewirken unterscheidet sich von der Liropol-Maschine dadurch, dass an den Stellen zwischen den Nadeln vor den vorderen Polplatinen bewegliche Zusatzpolplatinen vorhanden sind. Sie sind zur Lieferung der Fadenreserve für die Bildung der Schlaufe aus Polfadenmaterial heb- und senkbar (siehe z.B. DE-A-2 421 868).The machine for the production of loop-loop-knitted pile loop knits differs from the Liropol machine in that there are movable additional pile boards at the locations between the needles in front of the front pile boards. They can be raised and lowered to supply the thread reserve for forming the loop from pile thread material (see e.g. DE-A-2 421 868).

Verglichen mit der Liropol-Maschine ist der Aufbau dieser bekannten Maschine aufgrund des Einschaltens von Zusatzpolplatinen mit separatem Antrieb noch komplizierter.Compared to the Liropol machine, the construction of this known machine is even more complicated due to the switching on of additional pole boards with a separate drive.

Bekannt ist schliesslich noch eine Einrichtung zur Herstellung von Polschlingengewirken an einer Liropol-Wirkmaschine, die unter den Wirknadeln angeordnete Kulierplatinen ausweist, deren Kulierende zu der Antriebseinrichtung der Wirknadeln geschwenkt ist, die auf einem beweglichen Kamm mit einer hin-und hergehenden Bewegung montiert sind. Diese Einrichtung erleichtert teilweise die Beanspruchung der Strickfäden beim Strickprozess.Finally, there is also known a device for producing pile loop knitted fabrics on a Liropol knitting machine, which has sinkers arranged under the knitting needles, the sinkers of which are pivoted to the drive device of the knitting needles, which are mounted on a movable comb with a reciprocating movement. This device partially eases the stress on the knitting threads during the knitting process.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, ein Polschlingengewirke mit verbesserten Eigenschaften hinsichtlich der Maschenfestigkeit und der Festigkeit beim Ziehen von vorderen Polfäden, bei dem sich Naturfasergarne als Wirkfäden in einer umfassenden Maschenstrukturplatte verwenden lassen, ein Verfahren zur Herstellung eines solchen Polschlingengewirkes, das eine feste Bindung der vorderen Polfäden in jeder Maschenreihe mit den Fransemaschen gewährleistet und die Herstellung mannigfaltiger Maschenstrukturen erlaubt, sowie eine Maschine zur Herstellung des Polschlingengewirkes mit mannigfaltiger Struktur zu schaffen, mit der bei einfachem Aufbau die Fadenspannung und die Fadenbruchhäufigkeit reduziert werden kann.The object on which the invention is based is to provide a pile loop knit with improved properties with regard to the stitch strength and the strength when pulling the front pile threads, in which natural fiber yarns can be used as knitting threads in a comprehensive mesh structure plate, a method for producing such a pile loop knit fabric, which ensures firm binding of the front pile threads in each stitch row with the fringed stitches and allows the production of varied stitch structures, and a machine for producing the To create pile loop knitted fabrics with a diverse structure, with which the thread tension and the thread break frequency can be reduced with a simple structure.

Diese Aufgabe wird ausgehend von einem Polschlingengewirke, das aus einem Warengrund bzw. einer Grundware besteht, der bzw. die von den Maschenstäbchen der in geschlossener Franse gelegten Bindekettfäden und einem Schussfadensystem, die zwischen den Platinen- und Nadelmaschen der Franse abgebunden sind, und von vorderen und hinteren Polfäden gebildet wird, wobei die hinteren Polfäden jeweils zwischen zwei benachbarten Maschenstäbchen zwischen den Nadel- und Platinenmaschen der Franse gebunden sind, erfindungsgemäss dadurch gelöst, dass die vorderen Polfäden als Plattierschlingen der Franse in zwei aufeinanderfolgenden Maschenreihen von zwei benachbarten Maschenstäbchen gewirkt sind und ein oder mehrere Schussfadensysteme gleich- oder gegenlegig unter einem oder mehreren Maschenstäbchen gelegt und zwischen den Platinen- und Nadelmaschen der Franse gebunden sind und zwischen den Platinen- und Nadelmaschen der vorderen Plattierpolschlingen verlaufen.This task is based on a pile loop knitted fabric, which consists of a fabric base or a basic fabric, the or of the wales of the binding warp threads laid in a closed fringe and a weft thread system, which are tied between the sinker and needle stitches of the fringe, and from the front and the rear pile threads are formed, the rear pile threads each being tied between two adjacent wales between the needle and sinker loops of the fringe, according to the invention solved in that the front pile threads are knitted as plating loops of the fringe in two successive courses of two adjacent wales and one or several weft thread systems placed in the same or opposite direction under one or more wales and are bound between the sinker and needle stitches of the fringe and run between the sinker and needle stitches of the front plating pile loops.

Bei der Maschine zur Herstellung eines Polschlingengewirkes mit zur Ebene vorderer und hinterer Polplatinen senkrecht verlaufenden Wirknadeln, zwischen denen ein Schusslochnadelsystem angeordnet ist, wobei hinter den hinteren Polplatinen Lochnadeln für die hintere Polfläche und vor den vorderen Polplatinen Lochnadeln für die vordere Polfläche und Lochnadeln für die Kettenwirkfäden angeordnet sind, sind erfindungsgemäss die Wirknadeln Zungennadeln. Zwischen den hinteren und vorderen Polplatinen sind zumindest zwei Schusslochnadelsysteme angeordnet. Auf der Seite der vorderen Polplatinen sind Lochnadeln für die vorderen Polfäden und die Lochnadeln für die Kettenwirkfäden symmetrisch unter und über der Ebene der Wirknadel angeordnet. Die Wirknadel kann eine Spitze aufweisen, unter der eine Schiebefläche ausgebildet ist.In the machine for producing a pile loop knitting with knitting needles running perpendicular to the plane of the front and rear pile sinkers, between which a weft-hole needle system is arranged, with hole needles for the rear pile face behind the rear pile sinkers and hole needles for the front pile face and hole needles for the warp knitting yarns in front of the front pile sinkers According to the invention, the knitting needles are latch needles. At least two shot hole needle systems are arranged between the rear and front pole boards. On the side of the front pile sinkers, perforated needles for the front pile threads and the perforated needles for the warp knitting threads are arranged symmetrically below and above the plane of the knitting needle. The knitting needle can have a tip under which a sliding surface is formed.

Erfindungsgemäss kann ein Polschlingengewirke mit maschenfestem Grund und Polschlingenbeständigkeit beim Ziehen der Polfäden in mannigfaltiger Struktur durch Kombination beider Schussfadensysteme hergestellt werden. Die hygienischen Eigenschaften des Gewirkes sind aufgrund der möglichen Anwendung von Wirkfadengarnen sehr gut. Aufgrund der reduzierten Fadenbruchhäufigkeit der Wirkfäden infolge der reduzierten dynamischen Beanspruchung bei der Legung lässt sich eine erhöhte Produktivität erreichen.According to the invention, a pile loop knitted fabric with a solid base and pile loop resistance when pulling the pile threads in a diverse structure can be produced by combining both weft thread systems. The hygienic properties of the knitted fabric are very good due to the possible use of knitting yarns. Due to the reduced thread break frequency of the knitting threads due to the reduced dynamic stress during laying, increased productivity can be achieved.

Die Wirknadel 1 besteht (Fig. 6) aus einem Schaft mit einem verjüngten Teil 19, in dessen vorderem Ende in einer Erweiterung über ein Gelenk 17 eine Zunge 18 gehalten und nach der Erweiterung ein Stutzen 21, der in einem Haken 20 mit einer Spitze 15 endet, ausgebildet ist, unter der eine Schiebefläche 16 vorgesehen ist.The needles 3 and 13, in which the knitting threads 9 and the pile threads 14 are drawn in, are arranged in front of the knitting needles 1. The perforated needles 6, in which the pile threads 12 are drawn in, are arranged behind the rear pile boards 8. The knitting needles 1 pass through a slot in the support rail 2, which is arranged behind the rear pole plates 8. The knitting needle 1 (FIG. 6) consists of a shaft with a tapered part 19, in the front end of which a tongue 18 is held in an extension via a joint 17 and, after the extension, a socket 21 which is in a hook 20 with a tip 15 ends, is formed, under which a sliding surface 16 is provided.

Das Polschlingengewirke wird folgendermassen hergestellt:

  • Am Beginn des Wirkzyklus bewegen sich die Wirknadeln 1 hin- und hergehend und laufen bei der Bewegung zum vorderen Totpunkt gemäss Fig. 2 zwischen den vorderen und hinteren Polplatinen 7 und 8 hindurch, über die unter ihnen durch die Lochnadeln 6 gelegten hinteren Polfäden 12 und die von den Lochnadeln 4 und 5 gelegten Schussfadensysteme 10 und 11. Das Legen der hinteren Polfäden 12 und der Schussfadensysteme 10 und 11 erfolgt durch eine waagerechte Bewegung nach links und rechts und eine senkrechte Bewegung der Lochnadeln nach unten und nach oben.
The pile loop knitted fabric is produced as follows:
  • At the beginning of the knitting cycle, the knitting needles 1 move back and forth and run during the movement to the front dead center according to FIG weft thread systems 10 and 11 laid by perforated needles 4 and 5. The back pile threads 12 and weft thread systems 10 and 11 are laid by a horizontal movement to the left and right and a vertical movement of the perforated needles downwards and upwards.

Die waagerechte und senkrechte Bewegung der beiden Schusslochnadelsysteme ist unabhängig voneinander und kann für eine gegebene Maschenreihe beliebig je nach der technologischen Aufgabe ausgelegt werden. Die waagerechte Bewegung der Lochnadel 6 verwirklicht die Legung der hinteren Polfäden über einer oder zwei Nadelteilungen. Über einer Nadelteilung weist das Gewirke keine linke Polfläche auf. Über zwei Nadelteilungen mittels der hinteren Polplatinen 8 weist das Gewirke eine linke Polfläche auf. Bei der weiteren Bewegung der Wirknadein zum vorderen Totpunkt öffnen die durch die vordere Maschenreihe gebildeten Maschen die Zungen 18 der Wirknadeln in der Zone der Maschenbildung, die sich zwischen den festen Polplatinen 7 und 8 befindet. Somit erreichen die Wirknadeln den vorderen Totpunkt mit geöffneten Zungen gemäss Fig. 3, wo die Legung der vorderen Polfäden 14 durch die Lochnadeln 13 und die Legung der Kettenwirkfäden 9 durch die Lochnadeln 3 erfolgt. Die Lochnadeln 3 legen in den Wirknadeln die Kettenwirkfäden 9 in Fransebindung. Die Lochnadeln 13 legen die vorderen Polfäden 14 in der Wirknadel in Trikotbindung. Das Wesen der Legung besteht in dem Legen der Fäden in den Stutzen 21 der Wirknadeln 1. Zur Bildung einer Maschenreihe führen die Lochnadeln 3 zwei Bewegungen durch, nämlich das Verlegen von einer Nadelteilung nach links oder nach rechts und eine schüttelnde Bewegung nach unten und nach oben. Die gleichen Bewegungen werden auch durch die Lochnadeln 13 ausgeführt, wobei sie von links nach rechts in den Wirknadeln für die gezeigte Maschenreihe legen, und bei der nächsten Maschenreihe die Lochnadeln 13 von rechts nach links legen. Jede L0chnadel 12[egtdiePolfäden 14 von zwei benachbarten Wirknadeln in zwei aufeinanderfolgenden Reihen und bildet mittels der vorderen Polplatten 7 eine rechte Polfläche.The horizontal and vertical movement of the two weft hole needle systems is independent of one another and can be arbitrary for a given stitch row depending on the technological task be interpreted. The horizontal movement of the perforated needle 6 realizes the laying of the rear pile threads over one or two needle divisions. The knitted fabric does not have a left-hand pile surface over a needle pitch. The knitted fabric has a left-hand pole face via two needle divisions by means of the rear pole plates 8. With the further movement of the knitting needles to the front dead center, the stitches formed by the front stitch row open the tongues 18 of the knitting needles in the stitch formation zone which is located between the fixed pole plates 7 and 8. The knitting needles thus reach the front dead center with the tongues open according to FIG. 3, where the front pile threads 14 are laid by the needles 13 and the warp knitting threads 9 are placed by the needles 3. The perforated needles 3 place the warp knitting threads 9 in fringed weave in the knitting needles. The perforated needles 13 place the front pile threads 14 in the knitting needle in a jersey weave. The essence of the laying consists in the laying of the threads in the stubs 21 of the knitting needles 1. To form a row of stitches, the perforated needles 3 carry out two movements, namely the laying of a needle pitch to the left or to the right and a shaking movement downwards and upwards . The same movements are also carried out by the needles 13, laying from left to right in the knitting needles for the row of stitches shown, and laying the needles 13 from right to left on the next row of stitches. Each pin 12 picks the pile threads 14 from two adjacent knitting needles in two successive rows and forms a right-hand pole face by means of the front pole plates 7.

Bei der Bewegung zum hinteren Totpunkt läuft die Wirknadel 1 durch die Zone der Maschenbildung gemäss Fig. 4, wobei die Masche der vorherigen Maschenreihe, die am Schaft der Wirknadel liegt, die Zungen 18 schliesst. Bei ihrer weiteren Bewegung zum hinteren Totpunkt befreit sich die Wirknadel von der alten Masche, die über der Zunge läuft und durch die auf der Abbildung gezeigten Walzen nach unten gezogen wird. Wenn die Wirknadel 1 den hinteren Totpunkt gemäss Fig. 5 erreicht, vollzieht sich eine Legung zwischen und ein Halten unter den Wirknadein 1 der hinteren Polfäden und der Schussfadensysteme durch die Lochnadeln 4, 5 und 6.4, the stitch of the previous stitch row, which lies on the shaft of the knitting needle, closes the tongues 18. As it continues to dead center, the knitting needle frees itself of the old stitch that runs over the tongue and is pulled down by the rollers shown in the illustration. When the knitting needle 1 reaches the rear dead center according to FIG. 5, a laying takes place between and a hold under the knitting needles 1 of the rear pile threads and the weft thread systems through the needles 4, 5 and 6.

Bei dem in Fig. 7 gezeigten Polschlingengewirke wird der Grund des Gewirkes von den Maschenstäbchen, die von den Kettwirkfäden 9 gewirkt und durch die Platinen- und Nadelmasche der Franse abgebunden sind, einem Schussfadensystem 10, das über vier Maschenstäbchen für die eine Maschenreihe gelegt ist und von einem Schussfadensystem 11 gebildet, das durch die Platinen- und Nadelmasche der Franse abgebunden und über vier Maschenstäbchen für die nächste Maschenreihe gelegt ist. Die vorderen Polfäden 14 sind als plattierende Schlingen der Franseschlingen durch die Kettwirkfäden 9 in zwei aufeinanderfolgenden Maschenreihen zwei benachbarter Maschenstäbchen gewirkt. Die hinteren Polfäden 12, die durch die Lochnadeln 6 gelegt sind, die die linke Polfläche bilden, sind in der Figur nicht gezeigt.In the pile loop knitted fabric shown in FIG. 7, the bottom of the knitted fabric is knitted by the wales, which are knitted by the warp knitting threads 9 and tied by the sinker stitch and needle stitch, a weft thread system 10, which is placed over four wales for one stitch row and formed by a weft thread system 11, which is tied through the sinker and needle stitch of the fringe and laid over four wales for the next course. The front pile threads 14 are knitted as plating loops of the fringe loops through the warp knitting threads 9 in two consecutive courses of two adjacent wales. The rear pile threads 12, which are laid through the perforated needles 6, which form the left pile surface, are not shown in the figure.

Bei dem in Fig. 8 gezeigten Polschlingengewirke wird der Grund des Gewirkes von Maschenstäbchen gebildet, die von den Kettwirkfäden 9 gewirkt sind, welche durch die Platinen- und Nadelmasche der Franse mit Schussfadensystemen 10 und 11 abgebunden sind, die gegenlegig über zwei Maschenstäbchen für jede Maschenreihe gebunden sind. Die vorderen Polfäden 14 und die hinteren Polfäden 12 im Gewirke sind zu dem Gewirke von Fig. 7 analog.In the pile loop knitted fabric shown in FIG. 8, the bottom of the knitted fabric is formed by wales, which are knitted by the warp knitting threads 9, which are tied by the sinker stitch and needle stitch with weft thread systems 10 and 11, which are opposed by two wales for each stitch row are bound. The front pile threads 14 and the rear pile threads 12 in the knitted fabric are analogous to the knitted fabric of FIG. 7.
