BESCHREIBUNG DESCRIPTION
VERFAHREN ZUM WEBEN EINES BANDES METHOD FOR WEAVING A TAPE
Die Erfindung bezieht sich auf ein Verfahren zum Weben eines Bandes auf eine Nadelbandwebmaschine, die mit zuei gegenläufig arbeitenden Schußnadeln, d.h. Schußschlaufen-Eintragnadeln arbeitet. Derartige Maschinen sind bekannt, z.B. aus der DE-PS 390 073. The invention relates to a method for weaving a ribbon on a needle ribbon weaving machine which works with weft needles working in opposite directions, i.e. Weft loop entry needles works. Such machines are known, e.g. from DE-PS 390 073.
Durch die vorliegende Erfindung soll ein Verfahren zum Herstellen eines Bandes geschaffen werden, das sich insbesondere als Gurtband für Sicherheitsgurte eignet. Bei derartigen Gurtbändern ist eine hohe Quersteifigkeit erwünscht, damit das Band einerseits glatt am Körper der zu sicherden Person anliegt, andererseits einwandfrei die Umlenkbeschläge durchläuft und sich gut aufuickeln läßt. Hierbei soll das Band eine möglichst kleine Aufuickelrolle bilden, so daß Einbauraum gespart uerden kann. The present invention is intended to provide a method for producing a belt, which is particularly suitable as a belt for seat belts. With such belt straps, a high degree of transverse stiffness is desired so that the belt rests smoothly on the body of the person to be secured on the one hand, and on the other hand runs smoothly through the deflection fittings and can be rolled up easily. Here, the tape should form the smallest possible roll, so that installation space can be saved.
Eine hohe Quersteifigkeit läßt sich durch Verwendung eines monofilen Schußfadens erreichen, der relativ hart ist. Die Härte dieses monofilen Schußfadens bringt es aber mit sich, daß seine Schußumkehrstellen rauhe Kanten des Bandes bilden, die zu einer unerwünschten Scheueruirkung führen, also Haut und Kleidung der gesicherten Person zerreiben bzw. abwetzen. A high transverse stiffness can be achieved by using a monofilament weft thread, which is relatively hard. However, the hardness of this monofilament weft thread means that its weft reversal points form rough edges of the tape, which lead to an undesirable abrasion effect, that is, to rub or scuff the skin and clothing of the secured person.
Das zu lösende Problem liegt nun darin, ein Verfahren zum Weben eines Bandes unter Verwendung eines monofilen Schußfadens zu schaffen, durch das sichergestellt wird, daß die Schußumkehrstellen des monofilen Schußfadens nicht an den Außenkanten des Bandes hervortreten. Dies läßt sich prinzipiell durch Randteile des Bandes erreichen, die, wie auch der Hauptteil des Bandes, mit einem multifilen Schußfaden gewebt werden. Dann aber tritt das Problem auf, wie man die Kopfreihen des monofilen sowie des multifilen Schußfadens sichern kann und außerdem ein Band er halten kann, das einen symmetrischen Eindruck erweckt, bei dem also beide Randteile allenfalls praktisch unmerkbare Unterschiede im Aussehen haben. The problem to be solved now is to provide a method of weaving a ribbon using a monofilament weft which ensures that the weft reversals of the monofilament weft do not emerge on the outer edges of the ribbon. This can in principle be achieved by edge parts of the band, which, like the main part of the band, are woven with a multifilament weft. Then, however, the problem arises of how to secure the head rows of the monofilament and the multifilament weft and also a tape can hold, which gives a symmetrical impression, so that both edge parts have at most practically imperceptible differences in appearance.
Diese Aufgabe wird durch die Erfindung gemäß Anspruch 1 gelöst, (in den folgenden Ausführungen werden auch die in den Ansprüchen definierten Begriffe verwendet.) This object is achieved by the invention according to claim 1 (the terms defined in the claims are also used in the following explanations).
Der Mittelteil des Bandes wird von beiden Schußnadeln gemeinsam gewebt, von denen die eine einen multifilen Schußfaden zuführt, der außerdem über die Breite der Randteile verläuft, während die andere Schußnadel einen Faden zuführt, der nur den Mittelteil des Bandes bildet. Dieser Faden ist vorzugsweise ein monofiler Faden. Falls erwünscht kann man jedoch statt dessen ebenfalls einen multifilen Faden, aber größerer Steifigkeit verwenden. Die beiden Randteile werden nur von der einen derbeiden Schußnadeln gewebt, wozu aus den Kettfäden beider Randteile je ein Teilhubfach (insbesondere Halbhubfach) gebildet wird, das nur von der einen der beiden Schußnadeln durchlaufen wird, währen die andere Schußnadel stehts außerhalb, d.h. oberhalb oder unterhalb dieses Teilhubfaches geführt wird. Die Köpfe der mit den Randteilkettfäden abbindenden Schußschiaufen werden durch eine außen am Randteil liegende, aus einem Hilfsfaden gebildete Maschenreihe gesichert. Dagegen werden die Köpfe der Schußschlaufen, die nur mit den Mittelteilkettfäden abbinden, durch eine aus einem weiteren Hilfsfaden gebildete Maschenreihe gesichert, die am Außenrand des Mittelteils und am Innenrand des benachbarten Randteils liegt, also weiter innerhalb des Bandes als die erstgenannte Maschenreihe. The middle part of the ribbon is woven together by both weft needles, one of which feeds a multifilament weft thread, which also runs across the width of the edge parts, while the other weft needle feeds a thread that only forms the middle part of the ribbon. This thread is preferably a monofilament thread. If desired, however, a multifilament thread can also be used instead, but with greater stiffness. The two edge parts are only woven by one of the two weft needles, for which purpose a partial lifting compartment (in particular a half-lifting compartment) is formed from the warp threads of both edge parts, which is only passed through by one of the two weft needles, while the other weft needle is always outside, i.e. is guided above or below this partial lift. The heads of the weft loops binding with the edge part warp threads are secured by a row of stitches located on the outside of the edge part and formed from an auxiliary thread. In contrast, the heads of the weft loops, which only bind with the middle section warp threads, are secured by a row of stitches formed from a further auxiliary thread, which lies on the outer edge of the middle section and on the inside edge of the adjacent edge section, that is to say further within the band than the first-mentioned stitch row.
Überraschenderweise hat sich herausgestellt, daß trotz dieser Unsymmetrie im Aufbau das Band einen symmetrischen Eindruck erweckt, daß die Uhsymmetrie also äußerlich nicht in Erscheinuung. tritt. Surprisingly, it has been found that, despite this asymmetry in the structure, the band gives a symmetrical impression, so that the clock symmetry does not appear externally. occurs.
Aus der EP-B1-0 147 621 ist es zwar bekannt, ein Gurtband zu weben, das einen Mittelteil hat, der aus einem monofilen und einem multifilen Schußfaden gewebt ist, wärend der eine Randteil nur mit dem multifilen Schußfaden gewebt wird. Hergestellt werden soll ein derartiges Gurtband mit separaten Nadeln oder Schützen. Es ist zwar möglich, ein Gurtband mit zwei derartigen Randteilen mit Schützen zu weben. Jedoch ist ein derartiges Webverfahren zu langsam und damit zu kostspielig. Eine Lehre, wie mit Schußnadeln ein Gurtband gewebt werden soll, das zwei Randteile hat, die nur aus dem einen, nämlich multifilen Faden gewebt werden, ist der genannten Patentschrift nicht zu entnehmen. From EP-B1-0 147 621 it is known to weave a belt webbing which has a middle part which is woven from a monofilament and a multifilament weft thread, while the one edge part only with the multifilament Weft is woven. Such a webbing should be manufactured with separate needles or shooters. It is possible to weave a belt with two such edge parts with shooters. However, such a weaving process is too slow and therefore too expensive. A teaching on how to use a weft needle to weave a belt that has two edge parts that are only woven from one, namely multifilament thread, is not to be found in the patent mentioned.
Vorzugsweise werden Hilfsfäden verwendet, die etwa das halbe Gewicht in dtex haben, wie die beiden gleich starken Schußfäden, damit die Maschenreihen möglichst wenig hervortreten. Auxiliary threads are preferably used, which have about half the weight in dtex, like the two equally strong weft threads, so that the course of the stitches emerge as little as possible.
Die Erfindung bezieht sich außerdem auf ein Verfahren zürn weben eines Bandes auf einer Nadelbandwebmaschine mit zwei gegenläufig arbeitenden Schußnadeln, wobei dieses Band keine Randteile besitzt und von beiden Schußnadeln durch Eintrag in ein gemeinsames Fach gewebt wird. Durch diese Variante der Erfindung soll ein absolut symmetrisches Band hergestellt werden, das in allen denjenigen Fällen anwendbar ist, wo Randteile nicht erforderlich oder nicht erwünscht sind. The invention also relates to a method for weaving a ribbon on a needle ribbon loom with two weft needles working in opposite directions, this ribbon having no edge parts and being woven by both weft needles by entry into a common compartment. This variant of the invention is intended to produce an absolutely symmetrical band which can be used in all those cases where edge parts are not required or are not desired.
Zur Lösung dieser Variante der Erfindung werden die Köpfe der gegenläufig eingetragenen Schußschlaufen durch zwei, aus je einem Hilfsfaden gebildeten Maschenreihen gesichert. Diese Maschenreihen befinden sich an den Außenkanten des Bandes. To solve this variant of the invention, the heads of the opposing weft loops are secured by two rows of stitches each made up of an auxiliary thread. These rows of stitches are located on the outer edges of the belt.
Vorteilhafterweise werden relativ dicke Hilfsfäden verwendet, so daß mit Sicherheit die von den Maschenreihen gehaltenen Köpfe der Schußschlaufen nicht mehr nach außen hervortraten und weiche Außenkanten des Bandes gebildet werden. Ausführungsbeispiele mit weiteren Merkmalen der Erfindung werden im folgenden anhand der Zeichnungen beschrieben. Relatively thick auxiliary threads are advantageously used, so that the heads of the weft loops held by the stitch rows no longer protrude outwards and soft outer edges of the band are formed. Exemplary embodiments with further features of the invention are described below with reference to the drawings.
Figur 1 zeigt in Draufsicht ein Gurtband mit Randteilen nach einer ersten Ausführungsform der Erfindung, wobei Mittelteil zum größten Teil weggebrochen ist, sowie die freien Enden von zwei Schußnadeln und die von ihnen zugeführten Schußfäden. Figure 1 shows a top view of a webbing with edge parts according to a first embodiment of the invention, the central part having broken away for the most part, as well as the free ends of two weft needles and the weft threads supplied by them.
Figur 2 zeigt in Draufsicht eine schematische Darstellung der hier wesentlichen Teile einer Nadelbandwebmaschine, bei maximal auswärts geschwenkten Schußnadeln. FIG. 2 shows a top view of a schematic representation of the essential parts of a needle ribbon loom, with the weft needles pivoted outward to the maximum.
Figur 3 desgleichen, mit maximal einwärts geschwenkten Schußnadeln. Figure 3 the same, with the weft needles pivoted inwards at most.
Figur 4 eine der Figur 3 entsprechende, jedoch perspektivische Darstellung. 4 shows a perspective view corresponding to FIG. 3.
Figur 5 zeigt in Draufsicht ein Gurtband ohne Randteile nach einer zweiten Ausführungsform der Erfindung, wobei die Mitte zum größten Teil weggebrochen ist, sowie die freien Enden von zwei Schußnadeln und die von ihnen zugeführten Schußfäden. FIG. 5 shows a top view of a belt webbing without edge parts according to a second embodiment of the invention, the middle having broken away for the most part, as well as the free ends of two weft needles and the weft threads supplied by them.
Erste Ausführungsform First embodiment
Das in Figur 1 dargestellte Gurtband hat einen Mittelteil 1 mit Kettfäden 3, einen linken Randteil 5 und einen rechten Randteil 6, beide mit Kettfäden 8. Die Kettfäden 8 der Randteile können, wie dargestellt, die gleiche Dicke haben wie die Kettfäden 3 des Mittelteils, aber auch dünner sein. Es werden zwei Schußfäden verwendet, nämlich ein multifiler Schußfaden 12, der über die ganze Breite des Bandes verläuft, also im Mittelteil und in den beiden Randteilen verwebt ist. Außerdem wird ein weiterer Schußfaden 10 verwendet, der nur mit den Kettfäden des Mittelteis verwebt ist, aber nicht in die beiden Randteile hineinreicht. Die ser Schußfaden ist vorzugsweise ein Monofil. Man kann jedoch auch für diesen einen Multifil verwenden. Im folgenden wird jedoch der Schußfaden 10 stets als Monofil bezeichnet. The belt webbing shown in FIG. 1 has a middle part 1 with warp threads 3, a left edge part 5 and a right edge part 6, both with warp threads 8. The warp threads 8 of the edge parts can, as shown, have the same thickness as the warp threads 3 of the middle part, but also be thinner. Two weft threads are used, namely a multifilament weft thread 12 which runs over the entire width of the band, that is to say is woven in the middle part and in the two edge parts. In addition, another weft thread 10 is used, which is only interwoven with the warp threads of the central part, but does not extend into the two edge parts. The This weft is preferably a monofilament. However, a multifilament can also be used for this. In the following, however, the weft thread 10 is always referred to as a monofilament.
Der die beiden Randteile 5, 6 bildende multifile Schußfaden 12 bildet rechts eine Reihe von Köpfen 14, die mit einem Hilfsfaden 16 unter Bildung einer Maschenreihe 18 gegen Aufziehen gesichert uerden. Diese Maschenreihe liegt ganz außen am Randteil 6. The multifilament weft thread 12 forming the two edge parts 5, 6 forms on the right a row of heads 14 which are secured against being drawn open with an auxiliary thread 16 to form a row of stitches 18. This row of stitches lies at the very outside on edge part 6
Der monαfile Schußfaden 10 wird durch eine weitere Maschenreihe 20 gesichert. Diese Maschenreihe wird aus einem Hilfsfaden 22 hergestellt und sichert eine aus dem monofilen Schußfaden 10 gebildete Reihe von Köpfen 24. Die Maschenreihe 20 liegt an der Grenze zwischen Mittelteil 1 und linkem Randteil 5, also ein Stück innerhalb des Gurtbandgeuebes. Der monofile Schußfaden 10 wird von einer rechten Schußnadel (genauer gesagt: Schußschlaufen-Eintragnadel) 26 eingetragen, der multifile Schußfaden 12 von einer linken Schußnadel 28. Von beiden Schußnadeln sind in Figur 1 nur die äußersten Enden dargestellt. The monofilament weft 10 is secured by a further course 20. This row of stitches is produced from an auxiliary thread 22 and secures a row of heads 24 formed from the monofilament weft thread 10. The course of stitches 20 lies on the border between the middle part 1 and the left edge part 5, that is to say a piece within the belt belt. The monofilament weft thread 10 is inserted by a right weft needle (more precisely: weft loop insertion needle) 26, the multifilament weft thread 12 by a left weft needle 28. Only the outermost ends of both weft needles are shown in FIG.
Die Figuren 2 bis 4 zeigen die hier wesentlichen Teile einer mit gegenläufigen Schußnadeln 26, 28 arbeitenden Bandwebmaschine. Die beiden Schußnadeln 26 und 28 sind durch ihre Arme 34 und 36 und diese durch nicht dargestellte aber bekannte Mittel synchron einwärts und außwärts bewegbar. Man erkennt links das fertig gewebte Gurtband 30, rechts die Kettfäden 3 des Mittelteils 1. Die Maschine hat ein Webblatt oder Riet 32. Die beiden Schußnadeln 26 und 28 werden von zwei um lotrechte Achsen schwenkbaren Armen 34 und 36 geführt. Die Schußnadel 26 ist durch ihren Arm 34 oberhalb der Schßnadel 28 geführt. Wie insbesondere Figur 4 zeigt, wird aus den Randteilkettfäden 8 rechts, d.h. vorne in Figur 4, ein Teilhubfach 38 (insbesondere Halbhubfach) gebildet, das etwa die untere Hälfte eines aus den Kettfäden 3 des Mittelteils gebildeten Hauptfaches 39 einnimmt. Ein gleiches Teilhubfach wird hinten in Figur 4, also am linken Rande gebildet. Die Schußnadel 28, die den multifilen Schußfaden 12 zuführt, wird durch diese beiden aus den Randteilkettfäden 8 gebildeten Teilhubfächer 38 und das Hauptfach 39 geführt, so daß deren Schußschlaufen mit allen Kettfäden verwebt werden. Dagegen wird die Schußnadel 26 im Hauptfach 39 oberhalb der beiden Teilhubfächer 38 geführt, so daß die von ihr zugeführten Schußschlaufen aus dem monofilen Schußfaden 10 nur mit den Kettfäden 3 des Mittelteils, dagegen nicht mit den Randteilkettfäden 8 verwebt werden. Figures 2 to 4 show the essential parts of a ribbon loom working with counter-weft needles 26, 28. The two weft needles 26 and 28 can be moved synchronously inwards and outwards by their arms 34 and 36 and these by means not shown but known. The finished woven webbing 30 can be seen on the left, the warp threads 3 of the middle part 1 on the right. The machine has a reed or reed 32. The two weft needles 26 and 28 are guided by two arms 34 and 36 which can be pivoted about vertical axes. The weft needle 26 is guided by its arm 34 above the weft needle 28. As shown in FIG. 4 in particular, a partial lifting compartment 38 (in particular a half-lifting compartment) is formed from the edge part warp threads 8 on the right, ie at the front in FIG. 4, which occupies approximately the lower half of a main compartment 39 formed from the warp threads 3 of the central part. An identical partial lifting compartment is formed at the rear in FIG. 4, that is to say on the left edge. The weft needle 28, which feeds the multifilament weft thread 12, is guided through these two partial lifting compartments 38 formed from the edge part warp threads 8 and the main compartment 39, so that their Weft loops can be woven with all warp threads. In contrast, the weft needle 26 is guided in the main compartment 39 above the two partial lifting compartments 38, so that the weft loops supplied by it from the monofilament weft thread 10 are woven only with the warp threads 3 of the middle part, but not with the edge part warp threads 8.
Die Maschine hat rechts und links der Bandwebstelle jeweils eine Wirknadel 40, 42, die durch nicht dargestellte Mittel in Richtung des Bandes hin und her schwenkbar ist, wie ein Vergleich der Figuren 2 und 3 zeigt. Die Köpfe der Wirknadeln 40 und 42 sind außwärts gerichtet und gegenüber einer waagerechten Ebene um etwa -10 Grad nach oben verdreht. Rechts und links von der Webstelle und außerhalb der Bahn der Wirknadeln ist je ein aufwärts gebogener Zungesicherungsdraht 44, 46 ortsfest montiert. Die beiden Hilfsfäden 16 und 22, die zur Herstellung der beiden Maschenreihen 18 und 20 (Fig. 1) dienen, uerden durch zwei Fadenführer 48 und 50 zugeführt. Diese Fadenführer sind an ihrem linken, nicht dargestellten Ende um waagerechte Achsen schwenkbar, wodurch ihre Ösen für die Hilfsfäden aufwärts und abwärts schwenkbar sind. The machine has a knitting needle 40, 42 on the right and left of the ribbon weaving loom, which can be pivoted back and forth in the direction of the ribbon by means not shown, as a comparison of FIGS. 2 and 3 shows. The heads of the knitting needles 40 and 42 are directed outwards and are rotated upward by approximately -10 degrees with respect to a horizontal plane. To the left and right of the weaving station and outside the path of the knitting needles, an upwardly bent tongue locking wire 44, 46 is mounted in a stationary manner. The two auxiliary threads 16 and 22, which are used to produce the two courses 18 and 20 (FIG. 1), are fed through two thread guides 48 and 50. These thread guides can be pivoted about horizontal axes at their left end, not shown, whereby their eyelets for the auxiliary threads can be pivoted upwards and downwards.
Vorzugsweise werden Schußfäden von etwa 550 dtex und Hilfsfäden von etwa 280 dtex verwendet. Weft threads of approximately 550 dtex and auxiliary threads of approximately 280 dtex are preferably used.
Zur Herstellung des Bandes werden nach dem Anschlag des Riets 32 das Hauptfach 39 für den Mittelteil und die beiden Teilhubfächer 38 für die Randteile umgestellt. Dann werden synchron von rechts und links die beiden Eintragnadeln 26, 28 eingeführt. Sobald annähernd die maximale Einschwenkstellung nach den Fig. 3 und 4 erreicht ist, werden von den beiden Fadenführern 48 und 50 die Hilfsfäden 16 und 22 durch eine etwa trapezförmige Fläche geführt, die gebildet wird aus den äußeren Enden der Schußnadeln 26, 28, den äußersten Randteilkettfäden 8 und den vom Gewebe herkommenden Schußfäden 10 bzw, 12. Die Hilfsfäden 16 und 22 uerden hierbei in die Köpfe der Wirknadeln 42, 44 eingelegt. Beim anschließenden Wiederausuärtsbewegen der Schußnadeln uerden von den Hilfsfäden 16, 22 die sich bildenden Köpfe der Schußfäden 10 und 12 mit den sich bildenden Maschenreihen 18 und 20 verwirkt. Die Zungesicherungsdrähte 44 und 46 sorgen in bekannter Weise dafür, daß nach dem Abschlagan der Maschen die Zungen der beiden Wirknadeln 40, 42 zunächst offen gehalten werden, wie es am besten in Figur 4 hinten erkennbar ist. Wie man aus Fig. 3 erkennt, wird die rechte, in Fig. 3 untere Maschenreihe an der Außenkante des Gurtbandes 30 gebildet, die linke, in Fig. 3 obere Maschenreihe jedoch etwas einwärts der Außenkante des Gurtbandes. To produce the tape, the main compartment 39 for the middle part and the two partial lifting compartments 38 for the edge parts are switched over after the reed 32 stops. Then the two entry needles 26, 28 are inserted synchronously from the right and left. 3 and 4, the auxiliary threads 16 and 22 are guided by an approximately trapezoidal surface, which is formed from the outer ends of the weft needles 26, 28, the outermost Edge warp threads 8 and the weft threads 10 and 12 coming from the fabric. The auxiliary threads 16 and 22 are inserted into the heads of the knitting needles 42, 44. When the weft needles are subsequently moved again, the heads of the weft threads 10 and 12 with the stitch rows 18 and 20 which are formed are interfered with by the auxiliary threads 16, 22. The tongue locking wires 44 and 46 ensure that the tongues of the two knitting needles 40, 42 are initially kept open after the stitch has been knocked off, as can best be seen at the rear in FIG. As can be seen from FIG. 3, the right row of stitches in FIG. 3 is formed on the outer edge of the webbing 30, but the left row of stitches in FIG. 3 is somewhat inward of the outer edge of the webbing.
Nach dem Auswartsschwenken der Schußnadeln 26, 28 und dem Anschlag des Riets 32 werden die Fächer wiederum umgestellt. Bei dem neuen Eintrag geht die untere Schuflnadel 28 wiederum durch die beiden Fächer 38 und 39, während die Schußnadel 26 wiederum nur durch das Hauptfach 39 tritt. After the weft needles 26, 28 have been pivoted outward and the reed 32 has stopped, the subjects are again switched over. In the new entry, the lower shovel needle 28 again passes through the two compartments 38 and 39, while the weft needle 26 in turn only passes through the main compartment 39.
Zweite Ausführungsform Second embodiment
Fig. 5 zeigt ein Band ohne Randteile. Das Band wird mit zwei gegenläufigen Schußnadeln 26, 28 gewebt, wozu jeweils ein einziges Fach gebildet wird. Bei dem hier dargestellten Band liegt der Monofil 10 unten, der Multifil 12 oben, was aber ohne prinzipielle Bedeutung ist. Die in Fig. 5 rechts liegenden Köpfe 60 der Schußschiaufen des Multifils 12 werden durch eine Maschenreihe 62 gesichert, die aus einem Hilfsfaden 64 gebildet wird. Die nach links hervortretenden Köpfe 66 der Schußschlaufen des Monofils 10 werden durch eine Maschenreihe 68 gesichert, die aus einem Hilfsfaden 70 gebildet wird. Fig. 5 shows a band without edge parts. The tape is woven with two opposing weft needles 26, 28, for which a single compartment is formed. In the band shown here, the monofilament 10 is at the bottom, the multifilament 12 is at the top, but this is of no fundamental importance. The heads 60 on the right in FIG. 5 of the weft loops of the multifilament 12 are secured by a course 62 which is formed from an auxiliary thread 64. The heads 66 of the weft loops of the monofilament 10 protruding to the left are secured by a course 68 which is formed from an auxiliary thread 70.
Vorzugsweise werden Schußfäden 10 und 12 von etwa 550 dtex verwendet und Hilfsfäden 64 und 70 von bis zu 1.100 dtex. Weft threads 10 and 12 of approximately 550 dtex are preferably used and auxiliary threads 64 and 70 of up to 1,100 dtex.
Zum Weben dieses Bandes wird nur ein Fach gebildet, durch das beide Schußnadeln geführt werden. Anordnung und Wirkung der Wirknadeln, der Zungensicherungsdrähte und der Fadenführer sind die gleichen wie obe anhand der Fig. 2 bis 4 beschrieben. Wie man aus Fig. 5 erkennt, sind die Maschenreihen 62 und 68 aus Hilfsfäden 64 und 70 gewirkt, die erheb lich dicker sind, als die Schußfäden 10 und 12. Hierdurch uerden weiche Außenkanten gebildet, die die Köpfe 60 und insbesondere 66 zuverlässig nach außen abdecken. To weave this ribbon, only one compartment is formed through which both weft needles are passed. The arrangement and effect of the knitting needles, the tongue locking wires and the thread guide are the same as described above with reference to FIGS. 2 to 4. As can be seen from Fig. 5, the courses 62 and 68 are knitted from auxiliary threads 64 and 70, which increase Lich are thicker than the weft threads 10 and 12. As a result, soft outer edges are formed which reliably cover the heads 60 and in particular 66 to the outside.
