Description

Die vorliegende Erfindung betrifft eine Fadenführeinrichtung zum Führen von Fäden.The present invention relates to a thread guiding device for guiding threads.

Fadenführeinrichtungen werden insbesondere in der Textilproduktion beim Herstellen oder Behandeln von Fäden für die entsprechende Textilproduktion gebraucht. Beispielsweise sind Fadenführeinrichtungen vor oder nachgeordnet zu einer Garnbearbeitungsdüse, wie beispielsweise einer Texturierdüse, angeordnet. Aus der WO 2006/002562 A1 ist beispielsweise eine Vorrichtung für das Behandeln von Filamentgarn sowie Knoten-, migriertem und falschgedralltem Garn bekannt geworden. Diese Vorrichtung weist eine Garnbehandlungsdüse auf. In Fadenlaufrichtung vor der Düse ist eine Fadenführeinrichtung angeordnet. Ebenfalls in Fadenlaufrichtung nach der Düse ist eine zweite Fadenführeinrichtung angeordnet. Der Fadenführer ist als einstückiges keramisches Element ausgebildet. Der Fadenführer ist dazu eingerichtet, mehrere Fäden parallel zu führen.Thread guide devices are used particularly in textile production when producing or treating threads for the corresponding textile production. For example, thread guide devices are arranged before or after a yarn processing nozzle, such as a texturing nozzle. From the WO 2006/002562 A1 For example, a device for treating filament yarn as well as knotted, migrated and false-twisted yarn has become known. This device has a yarn treatment nozzle. A thread guide device is arranged in front of the nozzle in the direction of thread travel. A second thread guide device is also arranged after the nozzle in the direction of thread travel. The thread guide is designed as a one-piece ceramic element. The thread guide is designed to guide several threads in parallel.

Je nach Belegung oder Beaufschlagung der Vorrichtung aus der WO 2006/002562 wird der Fadenführer jedoch ungleichmässig beansprucht und damit ebenso ungleichmässig abgenutzt. Zudem muss die Fadenführeinrichtung vollständig ausgetauscht werden, wenn eine der mehreren parallel angeordneten Fadenführungen beschädigt ist.Depending on the occupancy or loading of the device from the WO 2006/002562 However, the thread guide is subjected to uneven stress and is therefore also worn unevenly. In addition, the thread guide device must be completely replaced if one of the several thread guides arranged in parallel is damaged.

Es ist daher Aufgabe der Erfindung, Nachteile des Standes der Technik zu beheben. Insbesondere soll ein Fadenführer bereitgestellt werden, welcher einfach in der Herstellung, günstig in Betrieb und einfach zu warten ist.It is therefore the object of the invention to eliminate disadvantages of the prior art. In particular, a thread guide should be provided which is simple to manufacture, inexpensive to operate and easy to maintain.

Diese Aufgabe wird durch die in den unabhängigen Patentansprüchen definierten Vorrichtungen gelöst. Weitere vorteilhafte Ausführungsformen ergeben sich aus den abhängigen Patentansprüchen.This task is solved by the devices defined in the independent patent claims. Further advantageous embodiments result from the dependent patent claims.

Eine erfindungsgemässe Fadenführeinrichtung zum Führen von Fäden umfasst ein Basiselement und mindestens ein Deckelement und zumindest einen Fadenführer. Der zumindest eine Fadenführer ist in einer Ausnehmung des Basiselementes angeordnet. Der zumindest eine Fadenführer ist mit dem Deckelement am Basiselement lösbar gehalten. Die Erfindung wird exemplarisch anhand eines Fadenführers für Fäden erläutert. Unter dem Begriff Faden werden vorliegend jede Art von Garnen, Filamenten oder Filamentbündeln verstanden.A thread guiding device according to the invention for guiding threads comprises a base element and at least one cover element and at least one thread guide. The at least one thread guide is arranged in a recess in the base element. The at least one thread guide is detachably held on the base element by the cover element. The invention is explained using an example of a thread guide for threads. The term thread is used here to mean any type of yarn, filament or bundle of filaments.

Der Begriff gehalten umfasst auch eine Anordnung, bei der der Fadenführer lose gehalten und nur gegen Verlust gesichert ist. Ebenso wird unter gehalten ein festes Halten verstanden, bei dem der Fadenführer beispielsweise vorgespannt fixiert ist.The term held also includes an arrangement in which the thread guide is held loosely and only secured against loss. Likewise, held is understood to mean a firm hold in which the thread guide is fixed, for example in a pre-tensioned manner.

Der Fadenführer der Fadenführeinrichtung kann damit einfach ausgetauscht werden. Dazu muss lediglich das Deckelement entfernt bzw. geöffnet werden.The thread guide of the thread guide device can therefore be easily replaced. All you have to do is remove or open the cover element.

Der Fadenführer weist vorzugsweise quer zur bestimmungsgemässen Fadenbewegungsrichtung eine Öffnung zum Einlegen des Fadens auf.The thread guide preferably has an opening for inserting the thread transversely to the intended direction of thread movement.

Beispielhaft in der einfachsten Form ist der Fadenführer als Öse mit einem Schlitz ausgebildet. Das heisst, der Fadenführer weist quer zur Achse der Fadenbewegungsrichtung keine geschlossene Kontur auf.For example, in its simplest form, the thread guide is designed as an eyelet with a slot. This means that the thread guide does not have a closed contour transversely to the axis of the direction of thread movement.

Dies ermöglicht ein einfaches Einlegen des Fadens in den Fadenführer.This allows the thread to be easily inserted into the thread guide.

Die Ausnehmung im Basiselement kann quer zur bestimmungsgemässen Fadenbewegungsrichtung eine Öffnung zum Einschieben des Fadenführers aufweisen. Dadurch wird ein einfaches Einsetzen und Entfernen des Fadenführers in die Fadenführeinrichtung, insbesondere in das Basiselement, ermöglicht.The recess in the base element can have an opening for inserting the thread guide transversely to the intended direction of thread movement. This makes it possible to easily insert and remove the thread guide in the thread guide device, in particular in the base element.

Das Basiselement kann zwei oder mehr Ausnehmungen aufweisen. Dabei ist bevorzugt jeder Ausnehmung ein Fadenführer zugeordnet. Dadurch wird ein paralleles Führen von mehreren Fäden ermöglicht. Da jedem Faden ein separater Fadenführer zugeordnet ist, welcher austauschbar ist, kann die Abnutzung oder Beschädigung eines einzelnen Fadenführers der Fadenführeinrichtung unabhängig von den übrigen Fadenführer kompensiert werden. Das heisst, ein Austausch jedes einzelnen Fadenführers ist möglich, ohne dass die gesamte Fadenführeinrichtung ausgetauscht werden muss. Es ist aber auch denkbar, mehrere Fadenführer in Gruppen zusammenzufassen. Indem mehrere Fadenführer in Gruppen zusammengefasst werden, können die Herstellkosten gesenkt und die Handhabung vereinfacht werden. Typischerweise können Fadenführer in Vierergruppen zusammengefasst werden. Andere Gruppengrössen wie Zweier-, Dreiere oder auch grössere Gruppen sind denkbar.The base element can have two or more recesses. A thread guide is preferably assigned to each recess. This enables several threads to be guided in parallel. Since each thread is assigned a separate thread guide, which is replaceable, the wear or damage to an individual thread guide of the thread guide device can be compensated for independently of the other thread guides. This means that each individual thread guide can be replaced without having to replace the entire thread guide device. However, it is also conceivable to combine several thread guides into groups. By combining several thread guides into groups, manufacturing costs can be reduced and handling simplified. Typically, thread guides can be grouped into groups of four. Other group sizes such as groups of two, three or even larger groups are conceivable.

Das Deckelement weist zumindest einen Vorsprung zum Verhindern einer Bewegung des Fadenführers entgegen einer Einschubrichtung auf. Vorzugsweise ist der Vorsprung in Kontakt mit einer Fläche des Fadenführers bringbar. Dies ermöglicht eine einfache Gestaltung des Deckelementes für ein einfaches Sichern des Fadenführers gegen Verlust.The cover element has at least one projection to prevent movement of the thread guide against an insertion direction. Preferably, the projection can be brought into contact with a surface of the thread guide. This enables a simple design of the cover element for easy securing of the thread guide against loss.

Das Deckelement der Fadenführeinrichtung kann zumindest einen Steg mit einem freien Ende aufweisen. Der Steg ist zwischen je zwei benachbarten Ausnehmungen des Basiselementes angeordnet oder anordenbar. Dies ermöglicht es, einen Steg zwei Fadenführern zuzuordnen.The cover element of the thread guide device can have at least one web with a free end. The web is arranged between two adjacent recesses in the base element or can be arranged. This makes it possible to assign a web to two thread guides.

Vorzugsweise ist der Vorsprung am freien Ende des Steges ausgebildet. Somit können mit einem Vorsprung zwei Fadenführer in der Fadenführeinrichtung gehalten werden.The projection is preferably formed at the free end of the web. This means that two thread guides can be held in the thread guide device with one projection.

In einer bevorzugten Ausführungsform ist der Steg federnd ausgebildet. Dies ermöglicht einerseits das vorgespannte Halten der Fadenführer in der Fadenführeinrichtung und insbesondere im Basiselement. Andererseits kann durch Überwinden der Federkraft das Deckelement beispielsweise soweit ausgelenkt werden, dass ein Einsetzen oder eine Entnahme des Fadenführers aus dem Basiselement ermöglicht ist, insbesondere ohne Entfernen des Deckelementes.In a preferred embodiment, the web is designed to be resilient. On the one hand, this enables the thread guides to be held pre-tensioned in the thread guide device and in particular in the base element. On the other hand, by overcoming the spring force, the cover element can be deflected, for example, to such an extent that the thread guide can be inserted or removed from the base element, in particular without removing the cover element.

Die Entnahme und das Einfügen des Fadenführers in die Fadenführeinrichtung und insbesondere in das Basiselement ist damit erleichtert.This makes it easier to remove and insert the thread guide into the thread guide device and in particular into the base element.

Der zumindest ein Vorsprung im Deckelement kann durch einen Hinterschnitt oder eine Vertiefung, insbesondere eine Einfräsung, ausgebildet sein. Die Fertigung des Deckelementes ist damit vereinfacht.The at least one projection in the cover element can be formed by an undercut or a recess, in particular a milling. The production of the cover element is therefore simplified.

Vorzugsweise weist das Basiselement Durchführungen auf, wobei vorzugsweise das Deckelement und das Basiselement zumindest in Bezug auf die Ausnehmungen und Durchführungen eine im Wesentlichen geometrisch ähnliche Kontur aufweisen.The base element preferably has bushings, with the cover element and the base element preferably having a substantially geometrically similar contour, at least with respect to the recesses and bushings.

Wenn die Durchführungen im Basiselement z.B. im Wesentlichen U-förmig ausgebildet sind, sind die Ausnehmungen im Deckelement ebenfalls im Wesentlichen U-förmig ausgebildet.If the feedthroughs in the base element are, for example, essentially U-shaped, the recesses in the cover element are also essentially U-shaped.

Dies gewährleistet eine hohe Passgenauigkeit und verhindert, dass Teile des Deckelementes oder des Basiselementes sich in den Pfad, in welchem der Faden läuft, erstrecken. Insbesondere kann das Deckelelement so ausgebildet sein, dass die Fadenführerelemente gegen Stösse geschützt werden. Stösse können beispielsweise beim Einlegen der Fäden mit einer Anlegepistole geschehen. Indem das Deckelelement Aussparungen aufweist, die im Wesentlichen ähnlich sind wie die Aussparungen des Fadenführerelements, wird das Fadenführerelement im Wesentlichen abgedeckt und dadurch geschützt.This ensures a high accuracy of fit and prevents parts of the cover element or the base element from extending into the path in which the thread runs. In particular, the cover element can be designed in such a way that the thread guide elements are protected against impacts. Shocks can occur, for example, when inserting the threads with a gun. Because the cover element has recesses that are essentially similar to the recesses of the thread guide element, the thread guide element is essentially covered and thereby protected.

Das Deckelement kann einen gemeinsamen Vorsprung für zwei Fadenführer aufweisen. Wie vorliegend dargelegt, ermöglicht dies das Halten von zwei Fadenführern mit nur einem Vorsprung.The cover element can have a common projection for two thread guides. As explained here, this allows two thread guides to be held with only one projection.

Das Deckelement kann mit dem Basiselement verschraubt oder verschraubbar sein. Ein einfacher Austausch und eine Demontage des Deckelementes ist damit ermöglicht. Dies ermöglicht somit ebenfalls ein einfaches Austauschen der Fadenführer.The cover element can be screwed or screwed to the base element. This makes it possible to easily replace and dismantle the cover element. This also makes it easy to replace the thread guides.

Das Deckelement kann mit dem Basiselement gelenkig und insbesondere verschwenkbar verbunden sein. Zum Fixieren des Deckelementes kann dazu beispielsweise ein Schnellverschluss vorgesehen sein. Als Schnellverschluss ist beispielswiese ein Bajonett- oder ein Kniehebelverschluss denkbar.The cover element can be connected to the base element in an articulated and in particular pivotable manner. For example, a quick-release fastener can be provided to fix the cover element. A bayonet or toggle lock, for example, is conceivable as a quick-release fastener.

Die gelenkige Verbindung kann als Drehachse ausgebildet sein Beispielsweise kann die Drehachse parallel zur Fadenbewegungsrichtung angeordnet sein, so dass das Deckelement quer zur Fadenbewegungsrichtung im gattungsgemässen Gebrauch nach oben geklappt werden kann. Dabei kann ein Schnellverschluss am Deckelement gegenüber der gelenkigen Verbindung angeordnet sein.The articulated connection can be designed as an axis of rotation. For example, the axis of rotation can be arranged parallel to the direction of thread movement, so that the cover element can be folded up transversely to the direction of thread movement in generic use. A quick-release fastener can be arranged on the cover element opposite the articulated connection.

Es ist aber ebenso vorstellbar, dass die gelenkige Verbindung quer zur Fadenbewegungsrichtung angeordnet ist und das Deckelement in Fadenbewegungsrichtung vom Basiselement wegklappbar ist. Das heisst, im gattungsgemässen Gebrauch ist das Deckelement in Fadenbewegungsrichtung weg- und anschliessend nach unten klappbar.However, it is also conceivable that the articulated connection is arranged transversely to the direction of thread movement and the cover element can be folded away from the base element in the direction of thread movement. This means that in generic use the cover element can be folded away in the direction of thread movement and then folded downwards.

Dies ermöglicht ein einfaches Handling des Deckelementes. Es ist ebenso zuverlässig gegen Verlust gesichert. Zusätzliche Schrauben zum Befestigen des Deckelementes sind nicht nötig. Das Risiko eines Verlustes von separaten Teilen ist damit zuverlässig vermindert.This enables easy handling of the cover element. It is also reliably secured against loss. Additional screws to fasten the cover element are not necessary. The risk of losing separate parts is therefore reliably reduced.

Der Fadenführer kann einen Querschnitt zum Eingriff in das Basiselement aufweisen, der derart ausgebildet ist, dass der Fadenführer in bestimmungsgemässen Gebrauch das Basiselement mindestens teilweise beidseitig umgreift. Der Querschnitt zum Kontakt mit dem Basiselement kann dabei insbesondere zum Bilden einer im Wesentlichen rechtwinkligen Nut-Nockenverbindung ausgebildet sein.The thread guide can have a cross section for engagement in the base element, which is designed such that the thread guide at least partially surrounds the base element on both sides when used as intended. The cross section for contact with the base element can be designed in particular to form a substantially rectangular groove-cam connection.

Beispielsweise weist der Querschnitt, der zum Eingriff mit dem Basiselement vorgesehen ist, im Wesentlichen ein U-Profil auf. Das U-Profil kann entlang der Verbindung aber auch unterbrochen sein. In Fadenbewegungsrichtung eingangsseitig und ausgangsseitig des Fadenführers können sich daher einzelne Nocken oder Vorsprünge befinden, die beispielsweise umlaufend des Fadenführers alternierend oder aber auch gleichmässig angeordnet sein können.For example, the cross section that is intended to engage with the base element essentially has a U-profile. The U-profile can also be interrupted along the connection. Individual cams or projections can therefore be located in the direction of thread movement on the input and output sides of the thread guide, which can, for example, be arranged alternately or evenly around the thread guide.

Dies ermöglicht ein einfaches Einschieben und Entfernen des Fadenführers in das Basiselement.This allows the thread guide to be easily inserted and removed into the base element.

Der Fadenführer kann aus einem keramischen Material gefertigt sein. Dies vergrössert die Lebensdauer des Fadenführers. Gemäss einer weiteren bevorzugten Ausführungsform kann das Basiselement mit Entlüftungsaussparungen versehen werden. Die abströmende Luft kann so unter dem Fadenführer abgeführt werden und stört den Faden weniger. Mit einer ruhigeren Fadenführung kann eine bessere Luftverwirbelung erreicht werden.The thread guide can be made of a ceramic material. This increases the lifespan of the thread guide. According to a further preferred embodiment, the base element can be provided with ventilation recesses. The outflowing air can be removed under the thread guide and disturbs the thread less. With a quieter thread guide, better air turbulence can be achieved.

Die Figur 1 zeigt eine Fadenführeinrichtung 100 in einer Explosionsdarstellung. Die Fadenführeinrichtung 100 weist ein Basiselement 1 und ein Deckelement 2 auf. In bestimmungsgemässen Gebrauch ist das Basiselement 1 und das Deckelement 2 über Schrauben 13 miteinander verbunden, welche in Schraubenlöcher 13' eingreifen. Schrauben 14 sind zur Befestigung des Fadenführers an einem, zur Befestigung der Fadenführeinrichtung 100 geeignetem, Gegenstück (nicht gezeigt) vorgesehen.The Figure 1 shows a thread guide device 100 in an exploded view. The thread guide device 100 has a base element 1 and a cover element 2. When used as intended, the base element 1 and the cover element 2 are connected to one another via screws 13, which engage in screw holes 13 '. Screws 14 are provided for fastening the thread guide to a counterpart (not shown) suitable for fastening the thread guiding device 100.

Im Basiselement 1 sind mehrere Ausnehmungen 11 angeordnet, zur besseren Übersicht ist jedoch jeweils nur ein Element mit einer Referenznummer bezeichnet. Jede Ausnehmung 11 weist eine, in vorliegender Abbildung nach oben gerichtete, Öffnung 12 auf. Dabei ist in jeder Ausnehmung 11 ein Fadenführer 3 angeordnet. Der Fadenführer 3 wird nachfolgend unter Bezugnahme auf die Figuren 2a und 2b im Detail erläutert.Several recesses 11 are arranged in the base element 1, but for better clarity only one element is designated with a reference number. Each recess 11 has an opening 12 which is directed upwards in the present illustration. A thread guide 3 is arranged in each recess 11. The thread guide 3 is explained in detail below with reference to Figures 2a and 2b.

In der Figur 1 sind zwei Fadenführer 3 gezeigt, welche sich in einer Einschubrichtung E oberhalb der Ausnehmung 11 befinden. Durch das Bewegen der Fadenführer 3 in die Einschubrichtung E sind die Fadenführer 3 in die Ausnehmung 11 einsetzbar. Jeder Fadenführer 3 weist eine Kontaktfläche 32 auf (siehe Figur 2 und 3). Die Kontaktfläche 32 ist beidseits durch einen vorstehenden Nocken 34 begrenzt und bildet zusammen mit den Nocken 34 eine Nut 35. Diese Nut 35 weist eine Breite zwischen den Nocken 34 auf, die im Wesentlichen der Dicke des Basiselementes 1 (siehe Figur 1) entspricht. Das heisst, beim Einschub der Fadenführer 3 in die Ausnehmung 11 des Basiselementes 1 gleitet diese Nut entlang einer korrespondierenden Struktur 16 des Basiselementes 1. Die beidseitig der Kontaktfläche 32 angeordneten Nocken 34 umgreifen dabei die korrespondierende Struktur 16 des Basiselementes 1. Somit ist der Fadenführer gegen ein Verschieben in Fadenbewegungsrichtung F (oder entgegen dieser Richtung) gesichert.In the Figure 1 Two thread guides 3 are shown, which are located above the recess 11 in an insertion direction E. By moving the thread guides 3 in the insertion direction E, the thread guides 3 can be inserted into the recess 11. Each thread guide 3 has a contact surface 32 (see Figure 2 and 3 ). The contact surface 32 is delimited on both sides by a projecting cam 34 and, together with the cams 34, forms a groove 35. This groove 35 has a width between the cams 34 which is essentially the thickness of the base element 1 (see Figure 1 ) corresponds. This means that when the thread guides 3 are inserted into the recess 11 of the base element 1, this groove slides along a corresponding structure 16 of the base element 1. The cams 34 arranged on both sides of the contact surface 32 encompass the corresponding structure 16 of the base element 1. The thread guide is therefore against a displacement in the thread movement direction F (or against this direction) is ensured.

Sobald alle Fadenführer 3 in die entsprechenden Ausnehmungen 11 durch die Öffnung 12 eingesetzt sind, wird das Deckelement 2 mit dem Basiselement 1 verbunden, um eine funktionstüchtige Einheit bereitzustellen.Once all thread guides 3 are inserted into the corresponding recesses 11 through the opening 12, the cover element 2 is connected to the base element 1 to provide a functional unit.

Das Deckelement 2 weist Durchführungen 24 auf, deren Kontur im Wesentlichen der Kontur der Ausnehmungen 11 des Basiselementes 1 entsprechen. In einer Anlagefläche 25 des Deckelementes 2 ist eine Einfräsung 23 vorgesehen. Die Einfräsung 23 ist derart ausgebildet, dass an einzelnen Stegen 22, die zwischen den Durchführungen 24 angeordnet sind, Vorsprünge 21 gebildet werden. Die Einfräsung entspricht im Wesentlichen etwas mehr als der Dicke der beidseitig der Kontaktfläche 32 angeordneten Nocken (siehe Figur 2a).The cover element 2 has bushings 24, the contour of which essentially corresponds to the contour of the recesses 11 of the base element 1. A milling 23 is provided in a contact surface 25 of the cover element 2. The milling 23 is designed in such a way that projections 21 are formed on individual webs 22, which are arranged between the bushings 24. The milling essentially corresponds to slightly more than the thickness of the cams arranged on both sides of the contact surface 32 (see FIG. 2a).

Wenn das Deckelement 2 mit seiner Anlagefläche 25 auf einer korrespondierenden Anlagefläche 15 des Basiselementes 1 angeordnet ist, umgreift die Einfräsung 23 mit den Vorsprüngen 21 den Teil der Fadenführer 3 (nämlich einer der Nocken 34), welcher über das Basiselement 1 hervorsteht. Durch das Festschrauben des Deckelementes 2 mit den Schrauben 13 am Basiselement 2 sind somit alle Fadenführer 3 gegen Verlust gesichert. Ebenso verhindern die Vorsprünge 21 einen Verlust der Fadenführer 3 entgegen der Einschubrichtung. Auf Grund der Abdeckung der Fadenführer 3 mit dem Deckelelement 2 wird der in der Regel aus keramischem Material gefertigte Fadenführer ausserdem gegen Stösse und damit Beschädigungen von aussen geschützt.If the cover element 2 is arranged with its contact surface 25 on a corresponding contact surface 15 of the base element 1, the milling 23 with the projections 21 surrounds the part of the thread guides 3 (namely one of the cams 34) which protrudes beyond the base element 1. By screwing the cover element 2 with the screws 13 onto the base element 2, all thread guides 3 secured against loss. The projections 21 also prevent the thread guides 3 from being lost in the opposite direction to the insertion direction. Due to the cover of the thread guide 3 with the cover element 2, the thread guide, which is generally made of ceramic material, is also protected against impacts and thus damage from the outside.

Die Figuren 2 und 3 zeigen jeweils eine mögliche Ausführungsform eines Fadenführers 3. Der Fadenführer 3 in der Figur 2 ist im Wesentlichen als Öse ausgebildet, die quer zur Fadenbewegungsrichtung F (in der Figur 2 und 3 je als Pfeil dargestellt) eine Öffnung 31 aufweist. In einer Draufsicht (siehe Figur 6) auf die Öffnung 31 ist erkennbar, dass die Öffnung 31 schräg zur Fadenbewegungsrichtung ausgebildet ist. Dadurch wird ein direktes radiales Entfernen des Fadens aus dem Fadenführer 3 verhindert.The Figures 2 and 3 each show a possible embodiment of a thread guide 3. The thread guide 3 in the Figure 2 is essentially designed as an eyelet, which is transverse to the thread movement direction F (in the Figures 2 and 3 each shown as an arrow) has an opening 31. In a top view (see Figure 6 ) on the opening 31 it can be seen that the opening 31 is designed obliquely to the direction of thread movement. This prevents the thread from being removed radially from the thread guide 3.

Der Fadenführer der Figur 3 weist zur Sicherung des Fadens einen Fortsatz 33 auf, der in eine Öffnung 36 eingreift, mit dieser aber nicht verbunden ist. Dadurch ist es ebenfalls möglich, einen Faden in den Fadenführer einzulegen und radiales Entfernen des Fadens aus dem Fadenführer 3 zu verhindern (siehe auch Figur 7) .The thread guide of the Figure 3 To secure the thread, it has an extension 33 which engages in an opening 36 but is not connected to it. This also makes it possible to insert a thread into the thread guide and prevent radial removal of the thread from the thread guide 3 (see also Figure 7 ).

Figur 4 zeigt eine vergrösserte Darstellung eines Ausschnitts aus dem Basiselement 1 mit eingesetzten Fadenführern 3. Die Stege 22 des Basiselements 1 weisen jeweils einen Vorsprung 21 auf. Ein Vorsprung 21 ist in Kontakt mit der Kontaktfläche 32 (siehe Fig 2 und 3) jeweils am Ende eines Schenkels von zwei benachbarten Fadenführern 3. Dadurch werden die Fadenführer 3 entgegen der Einschubrichtung E in den Ausnehmungen 11 des Basiselements 1 gehalten. Figure 4 shows an enlarged view of a section of the base element 1 with inserted thread guides 3. The webs 22 of the base element 1 each have a projection 21. A projection 21 is in contact with the contact surface 32 (see Figs 2 and 3 ) each at the end of a leg of two adjacent thread guides 3. As a result, the thread guides 3 are held in the recesses 11 of the base element 1 against the insertion direction E.

Figur 5 zeigt eine Draufsicht auf das Basiselement 1 und (siehe rechte Seite in Figur 5) Schnittdarstellungen entlang der Ebene A-A und B-B. Figure 5 shows a top view of the base element 1 and (see right side in Figure 5 ) Sectional views along planes AA and BB.

Figuren 6 und 7 zeigen eine schematische Draufsicht auf die Fadenführer aus den Figuren 2 und 3. Figures 6 and 7 show a schematic top view of the thread guides from the Figures 2 and 3 .

Figur 8 zeigt eine alternative Ausführungsform einer Fadenführeinrichtung 100. Das Deckelelement 2 ist um eine Schwenkachse S verschwenkbar angeordnet. Zum Öffnen und Schliessen kann das Deckelelement 2 in Pfeilrichtung verschwenkt werden und mit einem nur schematisch dargestellten Verschlussbügel 16 an einem Vorsprung 16' des Basiselements 1 verschlossen werden. Figure 8 shows an alternative embodiment of a thread guide device 100. The cover element 2 is arranged to be pivotable about a pivot axis S. To open and close, the cover element 2 can be pivoted in the direction of the arrow and closed with a locking bracket 16, shown only schematically, on a projection 16 'of the base element 1.

Figur 9 zeigt eine alternative Ausführungsform von Fadenführern. Das Basiselement 1 und das Deckelelement 2 entsprechen in ihrem Aufbau im Wesentlichen der Ausführungsform gemäss Figur 1. Gleiche Teile werden nicht erneut bezeichnet oder beschrieben. Im Unterschied zu der Ausführungsform gemäss Figur 1 weist das Basiselement 1 Aussparungen 13 auf. Entsprechend ist das Deckelelement mit einer Ausnehmung 25 versehen. Die Ausnehmung 25 verläuft bei aufgesetztem Deckelelement 2 an ihrem oberen Rand im Wesentlichen kongruent mit den Aussparungen 13. Die Luft strömt im Wesentlichen in Fadenlaufrichtung quer zu den Fadenführern vorne und hinten aus der Düse. Die ausströmende Luft wird am Basiselement 1 abgelenkt und bringt das Garn in Schwingung. Dieser Effekt wird durch die Aussparungen 13 verringert. Im Unterschied zum Ausführungsbeispiel gemäss Figur 1 sind in Figur 9 mehrere (konkret vier) Fadenführer in Gruppen 5 zusammengefasst. Figure 9 shows an alternative embodiment of thread guides. The structure of the base element 1 and the cover element 2 essentially corresponds to the embodiment according to Figure 1 . The same parts will not be referred to or described again. In contrast to the embodiment according to Figure 1 the base element 1 has recesses 13. Accordingly, the cover element is provided with a recess 25. When the cover element 2 is in place, the recess 25 runs essentially congruently with the recesses 13 at its upper edge. The air flows out of the nozzle essentially in the thread running direction, transversely to the thread guides at the front and rear. The outflowing air is deflected at the base element 1 and causes the yarn to vibrate. This effect is reduced by the recesses 13. In contrast to the exemplary embodiment according to Figure 1 are in Figure 9 several (specifically four) thread guides grouped into groups 5.

Figuren 10a und 10b zeigen perspektivische Darstellungen auf die Gruppen 5 von Fadenführern gemäss Figur 9. In den Fadenführern sind optionale Aussparungen 6 vorgesehen, die einen zusätzlichen Führungseffekt bieten können. Figures 10a and 10b show perspective views of the groups 5 of thread guides according to Figure 9 . In the thread guides Optional recesses 6 are provided, which can provide an additional guiding effect.
