Description

Die Erfindung betrifft eine Häkelgalonmaschinennadel, d.h. eine Flottiernadel, die speziell zum Einsatz in einer Häkelgalonmaschine vorgesehen ist.The invention relates to a crochet galloon needle, i. a float needle specially designed for use in a crochet galloon machine.

Häkelgalonmaschinen sind Spezialmaschinen zur Herstellung von Textilbändern, wie beispielsweise Gurtbändern, Matrazenbändern, Reißverschlussbändern, Trägerbändern, beispielsweise von Büstenhaltern, elastischen Binden, Mullbinden oder dergleichen.Crochet galloon machines are special machines for the production of textile ribbons, such as straps, mattress ribbons, zipper ribbons, straps, for example brassieres, elastic bandages, gauze bandages or the like.

Eine Häkelgalonmaschine zur Herstellung von Textilbändern ist beispielsweise aus der DE 44 17 692 A1 und der DE 29 30 824 A1 bekannt. Die Maschine umfasst eine Gruppe im Gleichtakt längs vor und zurück bewegter Nadeln, die endseitig jeweils einen Haken mit federndem Schenkel tragen. Die Nadeln erzeugen jeweils eine Maschenware, die z.B. aus Maschenstäbchen bzw. Maschenketten besteht, die auch als "geschlossene Franse" bezeichnet werden. Eine Gruppe im Gleichtakt bewegter Lochnadeln legt dazu mindestens einen Grundfaden und gegebenenfalls auch zusätzlich einen elastischen Faden vor. Außerdem ist ein Fadenführer vorgesehen, der quer zu dem die Maschenkette bildenden Faden einen sogenannten Schussfaden unterlegt bzw. hin und her gehend einlegt. Dieser Schussfaden bindet sich in die Maschenketten.A Häkelgalonmaschine for the production of textile ribbons is for example from the DE 44 17 692 A1 and the DE 29 30 824 A1 known. The machine comprises a group in the same direction along forward and backward moving needles, each end carrying a hook with resilient leg. The needles each produce a knit fabric, which consists for example of wales or mesh chains, which are also referred to as "closed fringe". A group in the same time moving needle needles sets to at least one ground yarn and possibly also in addition an elastic thread. In addition, a yarn guide is provided, the underside of which forms the stitch chain thread underlaying a so-called weft thread or goes back and forth going. This weft binds in the mesh chains.

Eine derartige Häkelgalonmaschine erfordert hohe Abzugskräfte um ordnungsgemäß zu arbeiten. Die Abzugskräfte ziehen das Textilband von den Nadeln weg und strecken somit die noch in den Nadeln hängenden Halbmaschen, um genügend Raum für das sichere Einlegen des Schussfadens zu schaffen und um das Abwerfen neu gebildeter Maschen sicherzustellen. Mit steigender Warendichte muss die Warenabzugsspannung reduziert werden, um die kleinen Maschen, die zur Erzeugung einer hohen Warendichte notwendig sind, herzustellen. Bei textilen Flächen mit hoher Warendichte ist der Abstand des Maschenkopfes einer erzeugten Masche zu dem Maschengrund der Halbmasche die sich im Nadelhaken befindet sehr klein in besonderen Fällen nahezu gleich null. Dies erschwert das gesicherte Unterlegen eines Schussfadens zwischen Maschenkopf der erzeugten Masche und Maschengrund der Halbmasche. Abhängig von der Musterung des herzustellenden textilen Bandes kann ein Schussfaden alle Maschenketten oder nur einen Teil der Maschenketten eines Bandes verbinden. Im letzteren Falle wird der Schussfaden als Teilschussfaden bezeichnet.Such a crochet galloon machine requires high take-off forces in order to work properly. The pull-off forces pull the textile tape away from the needles and thus stretch the still hanging in the needles half-stitches to create enough space for the safe insertion of the weft thread and to ensure the ejection of newly formed stitches. With increasing product density, the fabric take-off tension must be reduced to produce the small stitches necessary to produce a high product density. In the case of textile fabrics with a high product density, the distance of the mesh head of a mesh produced to the mesh bottom of the semi-mesh located in the needle hook is very small and in special cases almost equal to zero. This complicates the secure underlaying a weft thread between the mesh head of the mesh produced and mesh bottom of the half-stitch. Depending on the pattern of the textile tape to be produced, a weft thread can connect all the stitches or only a part of the stitches of a tape. In the latter case, the weft is called a partial weft.

Davon ausgehend ist es Aufgabe der Erfindung, verbesserte Systemteile anzugeben, welche die prozesssichere Herstellung von Textilbändern mit hoher Warendichte ermöglichen.On this basis, it is an object of the invention to provide improved system parts, which allow the process-reliable production of textile tapes with high product density.

Diese Aufgabe wird durch die Häkelgalonmaschinennadel nach Anspruch 1 gelöst:

  • Die erfindungsgemäße Häkelgalonmaschinennadel weist einen Haken auf, der einen Hakeninnenraum begrenzt. An der vom Schaft weg weisenden HakenauĂźenseite ist ein Flottiervorsprung ausgebildet. Dieser erstreckt sich wie eine Nase von der HakenauĂźenseite weg. Er dient dazu, den Schussfaden beim Einlegen desselben in die ihm zu kommende Position in der Maschenware zu fĂĽhren. Aufgrund des erfindungsgemäßen Flottiervorsprungs an der Häkelgalonmaschinennadel kann die Fadenspannung des Schussfadens reduziert und trotzdem ein prozesssicheres Unterlegen des Schussfadens gewährleistet werden.
This object is achieved by the Häkelgalonmaschinennadel according to claim 1:
  • The Häkelgalonmaschinennadel invention has a hook, which limits a hook interior. At the side facing away from the shaft hook outside a Flottiervorsprung is formed. This extends like a nose away from the hook outside. It serves to guide the weft thread when inserting the same into the position to be approached in the knitwear. Due to the invention Flottiervorsprungs on Häkelgalonmaschinennadel the thread tension of the weft thread can be reduced and still a reliable underlaying of the weft thread can be ensured.

Der Flottiervorsprung stellt auch bei verringerter Abzugsspannung sicher, dass der Schussfaden, wenn er vorgelegt wird und die Nadeln ausgetrieben werden, in die gewünschte Schussfadenposition gelangt. Dies gilt insbesondere bei sehr dichten Textilien, die sonst aufgrund der prozessbedingten Reduzierung der Abzugsspannung nicht mehr gesichert hergestellt werden können.The flotation projection ensures, even with reduced withdrawal tension, that the weft yarn, when presented and the needles are expelled, reaches the desired weft position. This is especially true for very dense textiles that can not be made secured due to the process-related reduction of the withdrawal voltage otherwise.

Durch die notwendige Reduzierung der Abzugsspannung zur Herstellung von Maschenware mit erhöhter Maschendichte vermindern sich die auf die Häkelgalonmaschinennadel wirkenden Kräfte erheblich. Entsprechend sind auch die Fadenzugkräfte bei der Fadenzuführung an die veränderten Bedingungen anzupassen, so dass die auf die Lochnadeln oder sonstige am Maschenbildungsvorgang beteiligten Elemente (Systemteile) wirkenden Kräfte verändert werden.Due to the necessary reduction of the withdrawal tension for the production of knitwear with increased mesh density, the forces acting on the crochet galloon machine needle are reduced considerably. Accordingly, the yarn tension in the yarn feed to the changed conditions must be adjusted so that the forces acting on the hole needles or other elements involved in the stitch forming process (system parts) forces are changed.

Bei einer speziellen Ausführungsform ist die Hakeninnenseite um einen Mittelpunkt kreisförmig gekrümmt, der im Hakeninnenraum liegt. Die Außenkontur an der Hakenaußenseite weicht jedoch von der Kreisbogenform ab. Der hier angeordnet Flottiervorsprung weist vorzugsweise zumindest eine gerade Rampe auf, die von seiner Spitze zu einer Hakenunterseite hin verläuft, die auch als Nadelrücken angesehen werden kann. Die am Flottiervorsprung vorhandene Rampe ist vorzugsweise gerade. Sie kann aber auch abweichende Formen, beispielsweise eine S-Form oder dergleichen aufweisen. In Querrichtung ist die Rampe vorzugsweise gerundet, so dass sie ohne scharfe Kanten in die Flanken des Flottiervorsprungs und des Hakens übergeht.In a specific embodiment, the hook inner side is circularly curved about a center which lies in the hook interior. However, the outer contour on the outer hook side deviates from the circular arc shape. The flotation projection arranged here preferably has at least one straight ramp, which extends from its tip to a hook underside, which can also be regarded as a needle back. The ramp present on the float projection is preferably straight. But it can also have different shapes, such as an S-shape or the like. In the transverse direction, the ramp is preferably rounded, so that it passes without sharp edges in the flanks of the Flottiervorsprungs and the hook.

Der Flottiervorsprung kann eine zum Beispiel gerade ausgebildete Oberseite aufweisen. Vorzugsweise ist sowohl die Oberseite wie auch die Rampe gegen eine mit der Nadellängsrichtung übereinstimmende Mittelachse jeweils in einem Winkel geneigt. Der von der Oberseite mit der Mittelachse eingeschlossene Winkel ist dabei vorzugsweise geringer als der von der Rampe mit der Mittelachse eingeschlossen Winkel.The floating projection can have an upper side that is straight, for example. Preferably, both the upper side as well as the ramp are each inclined at an angle to a central axis coinciding with the needle longitudinal direction. The angle enclosed by the upper side with the central axis is preferably smaller than the angle enclosed by the ramp with the central axis.

Der Flottiervorsprung weist unabhängig von seiner sonstigen Form eine von dem Schaft weg weisende Spitze auf. Diese Spitze ist vorzugsweise gerundet. Vorzugsweise ist eine sphärische Rundung vorgesehen. Der Rundungsradius ist vorzugsweise geringer als der Rundungsradius der Hakeninnenseite. Die Spitze ist vorzugsweise oberhalb der durch den Krümmungsmittelpunkt der Hakeninnenseite gehenden Mittelachse angeordnet. Dadurch erhält der Flottiervorsprung eine ausgeprägte Leitwirkung für den Schussfaden.The Flottiervorsprung has regardless of its other form on a pointing away from the shaft tip. This tip is preferably rounded. Preferably, a spherical rounding is provided. The radius of curvature is preferably less than the radius of curvature of the hook inside. The tip is preferably arranged above the central axis passing through the center of curvature of the hook inner side. This gives the Flottiervorsprung a pronounced guiding effect for the weft.

Die Oberseite und die Rampe können, wie erwähnt, beide gerade ausgebildet sein. Die gedachte Verlängerung dieser Kanten schneidet sich vorzugsweise in einem Punkt, der oberhalb der durch den Krümmungsmittelpunkt der Hakeninnenkontur laufenden Mittelachse liegt. Dadurch erhält die Rampe einen großen Fangbereich, innerhalb dessen sie einen auftreffenden Schussfaden an die Nadelunterseite leiten kann.The top and the ramp may, as mentioned, both be straight. The imaginary extension of these edges preferably intersects at a point which lies above the central axis running through the center of curvature of the hook inner contour. This gives the ramp a large catch area within which it can guide an impacting weft to the bottom of the needle.

Die Flanken des Flottiervorsprungs können parallel zueinander oder aufeinander zu konvergierend ausgebildet sein. Sie können außerdem eben ausgebildet sein oder eine von der ebenen Kontur abweichende Form haben. Vorzugsweise hat der Flottiervorsprung eine Dicke von mindestens etwa 20% bis 30% der Nadeldicke.The flanks of the floating projection can be designed to converge parallel to one another or to one another. You can also be just trained or have a different shape from the flat contour. Preferably, the floating projection has a thickness of at least about 20% to 30% of the needle thickness.

In Figur 1 ist ein einfaches Beispiel einer mit einer Häkelgalonmaschine erzeugten bandförmigen Maschenware 10 ausschnittsweise dargestellt. Die Maschenware 10 umfasst mehrere als "geschlossene Fransen" bezeichnete, miteinander nicht vermaschte Maschenketten 11, 12, 13, 14, die nebeneinander angeordnet sind und jeweils durch einen eigenen Grundfaden 15, 16, 17, 18 gebildet werden. Die Längsrichtungen der jeweiligen Maschenketten 11, 12, 13, 14 stimmen mit der Längsrichtung des zu erzeugenden Textilbandes überein. Quer dazu ist ein Schussfaden 19 vorgesehen, der die Maschenreihen 11 bis 14 alternierend von einem Rand zum anderen durchquert und in die einzelnen Maschen eingebunden ist. Der Schussfaden 19 kann dabei näherungsweise rechtwinklig zur Längsrichtung der bandförmigen Maschenware beziehungsweise der Maschenketten 11 bis 14 verlaufen. Der Schussfaden 19 läuft deshalb immer nacheinander durch die gleichzeitig erzeugten, auf gleicher Höhe liegenden Maschen jeder Maschenkette 11 bis 14.In FIG. 1 a simple example of a belt-shaped knitted fabric 10 produced with a crochet galloon machine is shown in fragmentary form. The knitted fabric 10 comprises a plurality of "closed fringes", mutually non-meshed mesh chains 11, 12, 13, 14, which are arranged side by side and each formed by a separate ground yarn 15, 16, 17, 18. The longitudinal directions of the respective stitch chains 11, 12, 13, 14 coincide with the longitudinal direction of the textile tape to be produced. Transversely thereto, a weft thread 19 is provided which alternately traverses the rows of stitches 11 to 14 from one edge to the other and is integrated into the individual stitches. The weft thread 19 can run approximately at right angles to the longitudinal direction of the band-shaped knitwear or the stitch chains 11 to 14. Therefore, the weft thread 19 always runs in succession through the stitches of each stitch chain 11 to 14 that are produced at the same height at the same time.

Es kann, wie Figur 2 anhand der ersten Maschenreihe 11 zeigt, zusätzlich zu dem Grundfaden 15 ein weiterer Kettfaden 20 in die Maschenware eingebunden werden. Zum Beispiel ist der Grundfaden 15 ein nicht elastischer (harter) Faden während der Kettfaden 20 ein elastischer (weicher) Faden sein kann. Außerdem können die einzelnen Maschenketten 11, 12 usw. untereinander vermascht sein, wie es in Figur 2 ebenfalls angedeutet ist. Welche Bindungsart und welches Maschenbild letztendlich dabei genau erzielt werden, hängt von der Relativbewegung der am Maschenbildungsprozess beteiligten Systemteile ab, die nachfolgend erläutert werden.It can, like FIG. 2 11 shows, in addition to the main thread 15 another warp thread 20 are incorporated into the knitted fabric on the basis of the first course 11. For example, the ground yarn 15 is a non-elastic (hard) yarn while the warp yarn 20 may be an elastic (soft) yarn. In addition, the individual mesh chains 11, 12, etc. can be intermeshed with each other, as in FIG. 2 also indicated. Which type of binding and which stitch pattern will ultimately be achieved exactly depends on the relative movement of the system parts involved in the stitch formation process, which will be explained below.

Zu dem Maschenbildungssystem gehören Lochnadeln 21, die in einer ersten Barre 22 gehalten sind, sowie gegebenenfalls weitere Lochnadeln 23, die in einer zweiten Barre 24 gehalten sind. Die erste der Lochnadeln 21 kann zum Beispiel zur Führung des Grundfadens 15 vorgesehen sein. Weitere an der gleichen Barre gehaltenen Lochnadeln führen die Grundfäden der anderen Maschenketten. Die Lochnadel 23 ist dagegen zur Führung eines weiteren Kettfadens 20 vorgesehen. Weitere Lochnadeln der Barre 24 führen entsprechende Kettfäden.To the stitch formation system include perforated needles 21 which are held in a first bar 22, and optionally further needles 23, which are held in a second bar 24. The first of the piercing needles 21 may, for example be provided for guiding the ground yarn 15. More on the same bar held hole needles lead the staple threads of the other mesh chains. The perforated needle 23, however, is provided for guiding a further warp thread 20. Further hole needles of the Barre 24 lead corresponding warp threads.

Weiter ist zur Einlegung des Schussfadens 19 ein Fadenführer 25 vorgesehen, der während des Maschenbildungsprozesses für jede Maschenreihe einmal von einem Textilrand zum anderen traversiert und dabei den Schussfaden auf die soeben gebildeten Halbmaschen legt.Next, a yarn guide 25 is provided for the insertion of the weft thread 19, which traverses once during the stitch formation process for each course of stitches from one edge of the fabric to the other and thereby places the weft thread on the half-stitches just formed.

Zu dem Maschenbildungssystem gehören weiter Häkelgalonmaschinennadeln, die nachfolgend kurz als Nadel(n) 26 bezeichnet werden. Die Nadeln 26 sind endseitig in einer nicht weiter veranschaulichten Barre gefasst. Zusätzlich sind sie in einem Nadelbett 27 in Nadellängsrichtung verschiebbar gelagert. Die Nadeln 26 stützen sich in dem Nadelbett 27 in entsprechenden Nadelkanälen 54 ab, auf deren Boden sie beim Maschenbildungsprozess axial hin und her gleiten.The knitting system further includes crochet galloon needles, hereafter referred to as needle (s) 26. The needles 26 are taken at the end in a not further illustrated Barre. In addition, they are slidably mounted in a needle bed 27 in the needle longitudinal direction. The needles 26 are supported in the needle bed 27 in corresponding needle channels 54, on the bottom of which they slide axially back and forth during the stitch forming process.

Die Nadeln 26 sind untereinander gleich ausgebildet, so dass die nachfolgende Beschreibung einer Nadel 26 fĂĽr alle anderen Nadeln 26 entsprechend gilt.The needles 26 are identical to each other, so that the following description of a needle 26 applies to all other needles 26 accordingly.

Bei der Erfindung gilt besonders Augenmerk der Ausbildung der Nadel 26. Diese ist in den Figuren 3 und 4 gesondert veranschaulicht. Die Nadel 26 weist einen Schaft 28 auf, der, wie in Figur 3 veranschaulicht, gerade oder auch zu seinem in Figur 3 nicht links abgeschnittenen und somit nicht mehr dargestellten Ende gebogen oder gekröpft oder anderweitig ausgebildet sein kann. Der Schaft 28 geht zu seinem in Figur 3 rechten Ende hin, in einem Maschenbildungsteil 29 über. Entlang des Maschenbildungsteils 29 hat die Nadel 26 eine beispielsweise gerade ausgebildete auch als Nadelrücken bezeichnete untere schmale Seite 30.In the invention, particular attention is paid to the formation of the needle 26. This is in the FIGS. 3 and 4 separately illustrated. The needle 26 has a shaft 28 which, as in FIG FIG. 3 illustrated, straight or too his in FIG. 3 can not be bent or cranked or otherwise formed on the left cut and therefore not shown end. The shaft 28 goes to his in FIG. 3 right end, in a stitch forming part 29 over. Along the stitch forming part 29, the needle 26 has a lower narrow side 30, which is for example straight and also referred to as a needle back.

Die schmale Nadeloberseite 31 verläuft vom Schaft her kommend zunächst zum Beispiel parallel zu der schmalen unteren Seite 30 oder in geringer Neigung zu dieser. An einer Übergangsstelle 32 grenzt die Nadeloberseite 31 an einen Nadelkopf, der als Haken 33 ausgebildet ist und zu dem Maschenbildungsteil 29 gehört.The narrow needle top 31 extends from the shaft coming initially, for example, parallel to the narrow lower side 30 or at a slight inclination to this. At a transition point 32, the needle top side 31 adjoins a needle head, which is designed as a hook 33 and belongs to the stitch formation part 29.

Der Haken 33 umschließt einen Innenraum 34, der zu der schalen unteren Seite 30 hin von einem geraden Fortsatz 35 des Schafts 28 begrenzt wird. Der Fortsatz 35 geht in einen Hakenkopf 36 über, dessen Innenkontur eine z.B. kreisbogenförmige Hakeninnenseite 37 festlegt. Diese ist beispielsweise kreisbogenförmige um einen Mittelpunkt 38 gekrümmt. Die Mittelachse A ist durch diesen Mittelpunkt 38 verlaufend angenommen und verläuft durch eine gedachte Hakenmitte. Auch im Falle einer nichtkreisbogenförmigen Hakeninnenseite 37 verläuft die Mittelachse A mittig auf halber Höhe durch die Hakeninnenseite 37 oder mittig auf halber Höhe durch den Innenraum 34.The hook 33 encloses an interior 34 which is limited to the shell lower side 30 by a straight extension 35 of the shaft 28. The extension 35 merges into a hook head 36, the inner contour of which is e.g. circular arc-shaped hook inside 37 determines. This is curved, for example circular arc around a center 38. The central axis A is assumed to extend through this center 38 and extends through an imaginary hook center. Even in the case of a non-circular arc-shaped hook inner side 37, the central axis A runs centrally at half the height through the inner hook side 37 or centrally at half the height through the inner space 34.

Der Hakenkopf 36 einer in Figur 3 dargestellten Häkelgalonmaschinennadel weist an seiner gedachten in Figur 3 gestrichelt eingetragenen zu der Hakeninnenseite 37 in konstantem Abstand verlaufenden Hakenaußenseite 39 einen Flottiervorsprung 40 auf, der sich von dem Schaft 28 und dem Haken 33 weg erstreckt. Der Flottiervorsprung 40 ist nach unten, d.h. zu der unteren Seite 30 hin durch eine zum Beispiel gerade Rampe 41 und nach oben hin durch eine zum Beispiel gerade Oberseite 42 begrenzt. Die Rampe 41 und Oberseite 42 gehen an einer vorzugsweise gerundeten Spitze 43 ineinander über. Diese Spitze 43 ist vorzugsweise oberhalb der Mittelachse A angeordnet. Der Krümmungsradius der Spitze ist dabei vorzugsweise deutlich geringer als der Krümmungsradius der Innenseite 37.The hook head 36 of an in FIG. 3 shown crocheting machine needle points to his imaginary in FIG. 3 dashed registered to the hook inner side 37 at a constant distance extending outside hook 39 a Flottiervorsprung 40 which extends away from the shaft 28 and the hook 33. The Flottiervorsprung 40 is down, that is limited to the lower side 30 through a straight ramp 41, for example, and at the top by a straight top 42, for example. The ramp 41 and top 42 merge into one another at a preferably rounded tip 43. This tip 43 is preferably above the central axis A arranged. The radius of curvature of the tip is preferably significantly smaller than the radius of curvature of the inner side 37.

Außerdem liegt ein Schnittpunkt 44 zweier gedachter in Figur 3 gepunktet eingetragener Verlängerungen der Rampe 41 und der Oberseite 42 vorzugsweise oberhalb der Mittelachse A und außerdem vorzugsweise oberhalb einer Stelle 45, bei der die Hakeninnenseite 37 in die gerade Kontur eines vorzugsweise elastisch ausgebildeten Schenkels 46 übergeht. Mit anderen Worten, die Entfernung der Stelle 45 zu der Mittelachse A ist geringer als die Entfernung des Schnittpunkts 44 zu der Mittelachse A. Weiter ist der Schenkel 46 an seinem Ende vorzugsweise gerundet. Diese Rundung ist vorzugsweise in Übereinstimmung mit der Rundung der Spitze 43 ausgebildet.In addition, there is an intersection 44 of two imaginary in FIG. 3 dotted registered extensions of the ramp 41 and the top 42 preferably above the central axis A and also preferably above a point 45, in which the hook inner side 37 merges into the straight contour of a preferably elastically formed leg 46. In other words, the distance of the point 45 to the central axis A is less than the distance of the point of intersection 44 to the central axis A. Further, the leg 46 is preferably rounded at its end. This rounding is preferably formed in accordance with the rounding of the tip 43.

Der genannte Schenkel 46 ist im Wesentlichen gerade ausgebildet und liegt mit einem zum Beispiel etwas abgebogenen Ende 47 federnd an dem Schaft 28 oder in einer an demselben ausgebildeten Ausnehmung an.Said leg 46 is substantially straight and lies resiliently against the shaft 28 or in a recess formed thereon, for example, with an end 47 bent somewhat.

Der Flottiervorsprung 40 weist zwei Flanken 48, 49 auf, die, wie Figur 4 zeigt, als ebene Flächen ausgebildet sein können. Die Flächen konvergieren zum Beispiel zu der Spitze 43 hin. Allerdings können die Flanken 48, 49 auch bogenförmig gekrümmt oder anderweitig ausgebildet sein. Außerdem können sie parallel zueinander angeordnet sein. Die Flanken 48, 49 gehen vorzugsweise mit gerundeten Kanten in die zum Beispiel ebenfalls vorzugsweise ebenen Flächen der Oberseite 42 und der Rampe 41 über.The Flottiervorsprung 40 has two flanks 48, 49, which, as FIG. 4 shows, can be formed as flat surfaces. The surfaces converge toward the tip 43, for example. However, the flanks 48, 49 may also be arcuately curved or otherwise formed. In addition, they can be arranged parallel to each other. The flanks 48, 49 preferably merge with rounded edges into the, for example, also preferably flat surfaces of the upper side 42 and the ramp 41.

Jeder bekannte Haken einer Nadel kann unabhängig seiner Position, seiner Form und seines Querschnitts mit einem erfindungsgemäßen Flottiervorsprung 40 versehen sein.Any known hook of a needle, regardless of its position, its shape and its cross-section, may be provided with a floating projection 40 according to the invention.

Der Prozess der Textilherstellung wird nachfolgend anhand der Figuren 5 bis 7 am Beispiel der Maschenkette 11 und des Schussfadens 19 aus Figur 1 erläutert:

  • Zum Verständnis wird darauf hingewiesen, dass alle Nadeln 26 in dem Nadelbett 27 zueinander synchron bewegt werden. Ebenso werden die an einer gemeinsamen Barre gehaltenen Lochnadeln 21 zueinander synchron bewegt. Der Maschenbildungsprozess läuft ab, indem die Nadeln 26 in bekannter Weise vorwärts und rĂĽckwärts bewegt werden, wobei die Lochnadeln 21 darauf abgestimmt den Grundfaden 15 in bekannter Weise um die Nadel schlingen, um ihn zur Maschenbildung in den Haken 33 einzulegen, jeweils um eine neue Halbmasche 50 zu bilden. Wird die Nadel 26 danach ausgetrieben, läuft die Halbmasche 50 infolge der hohen auf die Maschenkette 11 einwirkenden Abzugskraft aus dem Haken 33 heraus auf den Schaft 28. Die Lochnadel 21 schlingt den Grundfaden 15 dann erneut um den Haken 33 und legt ihn in diesem ein. Bei RĂĽckzug der Nadel 26 gleitet die auf dem Schaft 28 sitzende Halbmasche 50 ĂĽber den Haken 33 ab wobei der von dem Haken 33 gefangene Faden durch die bei diesem Vorgang entstehende Masche gezogen wird. Dadurch entsteht im Innenraum 34 des Hakens 33 eine neue Halbmasche 50. Mit der neuen Halbmasche 50 ist wieder der in Figur 5 gezeigte Zustand erreicht.
The process of textile production is described below on the basis of FIGS. 5 to 7 the example of the mesh chain 11 and the weft thread 19 from FIG. 1 explains:
  • For the sake of understanding, it should be noted that all the needles 26 in the needle bed 27 are moved synchronously with each other. Likewise, the held on a common bar needle needles 21 are moved synchronously to each other. The stitching process is accomplished by advancing and retracting the needles 26 in a known manner, with the piercing needles 21 looped around the needle thread 15 in a known manner around the needle to be stitched into the hook 33, one new half stitch at a time 50 to form. If the needle 26 is then expelled, the half-stitch 50 runs out of the hook 33 out onto the shaft 28 as a result of the high pull-off force acting on the stitch chain 11. The piercing needle 21 then wraps the main thread 15 again around the hook 33 and places it in this position. Upon withdrawal of the needle 26, the semi-stitch 50 seated on the shaft 28 slides over the hook 33, whereby the thread caught by the hook 33 is pulled by the stitch formed during this process. This results in the interior 34 of the hook 33 a new half-stitch 50. With the new half-stitch 50 is again in FIG. 5 shown state reached.

Bei dem insoweit beschriebenen Vorgang muss die Abzugskraft, die auf die Maschenkette 11 einwirkt gerade so groß bemessen werden, dass der Maschenbildungsprozess fehlerfrei vonstatten geht. Besonderes Augenmerk verdient in diesem Zusammenhang das Einlegen des Schussfadens 19. Dieser wird wie Figur 5 und 6 zeigen, jeweils vor bzw. auf der zuletzt erzeugten Halbmasche 50 abgelegt. Die spezielle Form der Nadel 26, insbesondere die Wirkung ihres Flottiervorsprungs 40, stellt dabei sicher, dass der Schussfaden 19 an die gewünschte Stelle geleitet wird. Dies ist in Figur 7 nochmals gesondert veranschaulicht. Der vom Fadenführer abgelegte Teil des Schussfadens 19 kann beispielsweise etwa in Höhe der längs verlaufenden Mittelachse A oder auch leicht darüber, auf die Rampe 41 des Flottiervorsprungs 40 auftreffen. Beim Austreiben der Nadel 26 in Richtung des Pfeils 51 gleitet der Schussfaden 19 in seine Sollposition auf der Halbmasche 50. Diese Bewegung des Schussfadens 19 ist in Figur 7 durch einen Pfeil 52 angedeutet. Die Sollposition des Schussfadens 19 ist durch einen gestrichelten Kreis 53 angedeutet.In the process described so far, the peel force acting on the chain 11 must be just so large that the stitching process proceeds without error. Special attention deserves in this context, the insertion of the weft 19. This will be like FIG. 5 and 6 show, in each case before or on the last generated half-stitch 50 filed. The special shape of the needle 26, in particular the effect of their float projection 40, ensures that the weft thread 19 is directed to the desired location. This is in FIG. 7 again separately illustrated. The deposited by the thread guide part of the weft thread 19 can impinge, for example, approximately at the level of the longitudinal central axis A or slightly above it, on the ramp 41 of the Flottiervorsprungs 40. When expelling the needle 26 in the direction of the arrow 51, the weft thread 19 slides into its desired position on the half-stitch 50. This movement of the weft thread 19 is in FIG. 7 indicated by an arrow 52. The desired position of the weft thread 19 is indicated by a dashed circle 53.

Damit ist das korrekte Arbeiten des Maschenbildungssystems auch dann sichergestellt, wenn sehr dichte Maschenware hergestellt werden soll oder beispielsweise die Halbmasche 50 aufgrund nur geringer Abzugsspannung sehr klein ausfällt. Der Schussfaden 19 wird durch den Flottiervorsprung 40 jedenfalls in seine Sollposition geleitet. Die Nadel 26 hat somit einen großen Schussfadenfangbereich was ein sicheres und verschleißarmes Arbeiten der Häkelgalonmaschine ermöglicht.Thus, the correct operation of the stitch formation system is ensured even if very dense knit fabric to be produced or, for example, the half-stitch 50 is very small due to only low withdrawal voltage. The weft thread 19 is guided by the floatation projection 40 in any case to its desired position. The needle 26 thus has a large weft catching area which enables safe and low-wear operation of the crochet galloon machine.

Eine erfindungsgemäße Häkelgalonmaschinennadel 26 ist an ihrer Hakenaußenseite 39 mit einem Flottiervorsprung 40 versehen, dessen Spitze 43 vorzugsweise oberhalb der Mittelachse A der Nadel 26 angeordnet ist. Diese Nadel 26 weist einen vergrößerten Schussfadenfangbereich auf und eignet sich deshalb insbesondere zur Herstellung dichter Maschenware. Außerdem ermöglicht sie das Arbeiten mit verringerter Abzugsspannung und gegebenenfalls auch mit verringerter Schussfadenspannung. Dies trägt zur Erhöhung der Standzeit aller Systemteile bei.A Häkelgalonmaschinennadel 26 according to the invention is provided on its outer hook side 39 with a Flottiervorsprung 40, the tip 43 is preferably disposed above the central axis A of the needle 26. This needle 26 has an enlarged weft catching area and is therefore particularly suitable for producing dense knitwear. It also allows working with reduced withdrawal tension and possibly also with reduced weft tension. This contributes to increasing the service life of all system parts.
