Abstract

A method for building up a specific thread reservoir on a rotating balloon limiter (12) of a multiple-twist twisting spindle is characterised in that the thread is guided through a thread-guide eye (13) which is arranged on the upper balloon-limiter region at an angular distance from the radial exit of the thread from the spindle rotor. A multiple-twist twisting spindle with a rotating balloon limiter (12) for carrying out the method is characterised in that the balloon limiter (12) carries in its upper region, preferably at the upper balloon-limiter edge, a thread-guide eye (13) which is located at an angular distance from the radial exit (11) of the thread from the spindle rotor. <IMAGE>

Description

Bei Mehrfachdraht-Zwirnspindeln üblicher Bauart enthält der umlaufende Spindelteil (Spindelrotor) eine Fadenspeicherscheibe, auf deren äußerem Umfang sich der radial aus der Spindelhohlachse herausgeführte Faden über eine mehr oder weniger große Strecke herumlegt, bevor er unter Ballonbildung zu einem in der Verlängerung der Spindelachse angeordneten Fadenführer und weiter zu einer Abzugseinrichtung oder unmittelbar zu einem Aufwickelaggregat läuft. Die Fadenspeicherscheibe dient dem Zweck, zwischen dem radialen Austritt des Fadens aus der Spindel und dem Ballon eine gewisse Fadenreserve aufzunehmen, die ihrerseits eine stets gleichbleibende Fadenspannung und somit auch einen gleichmäßigen Zwirn gewährleistet. Die Fadenspeicherung mittels einer Fadenspeicherscheibe kann als trägheitslose Fadenbremse bezeichnet werden.In the case of multi-wire twisting spindles of the usual type, the rotating spindle part (spindle rotor) contains a thread storage disk, on the outer circumference of which the thread radially guided out of the hollow spindle axis lies over a more or less large distance before it ballooning to a thread guide arranged in the extension of the spindle axis and continues to a take-off device or directly to a take-up unit. The thread storage disk serves the purpose of taking up a certain thread reserve between the radial exit of the thread from the spindle and the balloon, which in turn ensures a constant thread tension and thus also ensures an even thread. The thread storage by means of a thread storage disk can be referred to as an inertia-free thread brake.

Mehrfachdraht-Zwirnspindeln ohne Fadenspeicherscheibe benötigen in der Regel eine Zwangsführung des Fadenballons (US-PS 2 127 921; US-PS 2 609 652; DE-PS 1 268 031). Derartige Zwirnspindeln reagieren auf Änderungen der inneren Fadenspannung (Abzugsspannung) oder der äußeren Fadenspannung (Spannungen im Fadenballon) sehr sensibel, was oft zu Fadenbruch führt. Eine erzwungene Fadenführung im Bereich des Fadenballons ist meist nur für sehr reißfeste Garne anwendbar.Multi-wire twisting spindles without a thread storage disk generally require positive guidance of the thread balloon (US Pat. No. 2,127,921; US Pat. No. 2,609,652; German Pat. No. 1,268,031). Such twisting spindles react very sensitively to changes in the inner thread tension (draw-off tension) or the outer thread tension (tension in the thread balloon), which often leads to thread breakage. A forced thread guide in the area of the thread balloon can usually only be used for very tear-resistant yarns.

Die in der DE-PS 1 268 031 beschriebene Lösung berücksichtigt diese erzwungene Fadenführung, indem der im Spindelrotorbereich zwangsgeführte Faden in einen mit dem Spindelrotor umlaufenden Teilabschnitt des Ballonbegrenzers übergeht. Der Ausgleich der Fadenspannung vollzieht sich in der Zone des mitrotierenden Teilabschnitts des Ballonbegrenzers oder eines koaxial und zylindrisch nach oben verlängerten Rotors.The solution described in DE-PS 1 268 031 takes this forced thread guidance into account by the thread, which is positively guided in the spindle rotor area, passing into a partial section of the balloon limiter which rotates with the spindle rotor. The compensation of the thread tension takes place in the zone of the rotating portion of the balloon limiter or in a coaxially and cylindrically elongated rotor.

In der CH-PS 417 418 wird als Speicherscheibenersatz ein mit dem Rotor der Zwirnspindel mitrotierender Ballonbegrenzer erwähnt.CH-PS 417 418 mentions a balloon limiter which rotates with the rotor of the twisting spindle as a storage disc replacement.

In der DE-PS 37 28 213 ist eine Zwirneinrichtung für eine dreifache Drallerteilung beschrieben, bei der die Zwirnspindel ebenfalls keine Speicherscheibe aufweist. Dabei wird der aus der Spindelhohlachse austretende Faden bis an den Rand des Spindelrotors geführt und dort an den mit dem Spindelrotor gleichsinnig umlaufenden Ballonbegrenzer übergeben. Entsprechend dieser Druckschrift hat man bei solchen Zwirnspindeln festgestellt, daß der Ballonfaden nur dann zur Anlage an der Innenwand des Ballonbegrenzers kommt, wenn der Ballonbegrenzer selbst mitdreht. Wäre dies nicht der Fall, so käme der Ballonfaden mindestens im unteren Bereich an dem Außenmantel des Spulentopfes zur Anlage (siehe dazu auch die DE-OS 30 25 698).DE-PS 37 28 213 describes a twisting device for triple twist distribution, in which the twisting spindle likewise has no storage disk. The thread emerging from the hollow spindle axis is guided to the edge of the spindle rotor and there to the Transfer the balloon limiter in the same direction with the spindle rotor. According to this document, it has been found with such twisting spindles that the balloon thread only comes into contact with the inner wall of the balloon limiter when the balloon limiter itself rotates. If this were not the case, the balloon thread would come to rest at least in the lower area on the outer jacket of the bobbin pot (see also DE-OS 30 25 698).

Die Speicherung am Innenmantel eines mitrotierenden Ballonbegrenzers kann man sich als Raumkurve des Fadens (leichte Spiralform) vorstellen. Der Ballonfaden bleibt infolge der Luftreibung im Spalt zwischen dem gegebenenfalls auch entgegengesetzt zum Spindelrotor und Ballonbegrenzer rotierenden Spulenträger bzw. Spulenträger-Schutztopf zurück, das heißt, der Faden wird abgebremst. Die Raumkurve des Fadens nimmt ihren Anfang an der Austrittsöffnung aus dem Spindelrotor, und sie endet im Übergang von der höchsten Berührungsstelle am Ballonbegrenzer zu einer im Spindeldeckel befindlichen Ballonfadenführeröse, oder aber bei Spindeln ohne Spindeldeckel direkt in der Ballonfadenführeröse.The storage on the inner jacket of a rotating balloon limiter can be thought of as a space curve of the thread (slight spiral shape). As a result of the air friction, the balloon thread remains in the gap between the bobbin holder or bobbin protection pot, which may also rotate counter to the spindle rotor and balloon limiter, that is, the thread is braked. The space curve of the thread begins at the outlet opening from the spindle rotor and ends at the transition from the highest point of contact on the balloon limiter to a balloon thread guide eyelet located in the spindle cover, or directly in the balloon thread guide eyelet for spindles without a spindle cover.

Beim Anlauf der Spindel trifft der Ballonfaden auf eine stehende Luftsäule, was seine Nacheilung gegenüber dem rotierenden Ballonbegrenzer zur Folge hat. Die Raumkurve des Fadenballons erstreckt sich dabei über einen gewissen Umfang der Spindel mit der möglichen Folge, daß der Ballonfaden sich spiralig um den Außenumfang des entgegengesetzt rotierenden Spuleninnentopfes winden kann. Infolge der Seilreibung würde damit der Ballonfaden abgeschnürt, was zu einem Fadenbruch führt.When the spindle starts up, the balloon thread hits a standing column of air, which results in its lagging behind the rotating balloon limiter. The space curve of the thread balloon extends over a certain circumference of the spindle with the possible consequence that the balloon thread can wind spirally around the outer circumference of the counter-rotating bobbin. As a result of the rope friction, the balloon thread would be pinched off, resulting in a thread break leads.

Es ist deshalb die Aufgabe der Erfindung, eine Zwirneinrichtung mit mitrotierendem Ballonbegrenzer für die mehrfache (zwei- und dreifache) Drallerteilung zu schaffen, bei der der mitrotierende Ballonbegrenzer als Speicherzone genutzt wird, ohne daß in der Anlaufphase der Spindel der Nachteil der Fadeneinschnürung um den Spulentopf eintritt.It is therefore the object of the invention to provide a twisting device with a rotating balloon limiter for multiple (double and triple) twist distribution, in which the rotating balloon limiter is used as a storage zone without the disadvantage of thread constriction around the bobbin in the start-up phase of the spindle entry.

Zur Lösung dieser Aufgabe dienen einerseits die Verfahrensweise gemäß Patentanspruch 1 und andererseits die konstruktive Lösung gemäß Patentanspruch 2.The method according to claim 1 and the constructive solution according to claim 2 serve to solve this problem.

Die an dem Ballonbegrenzer angebrachte Fadenführungsöse ist insbesondere an dem oberen, gerade noch vom Faden berührten Randbereich des Ballonbegrenzers angebracht. Die Fadenführungsöse liegt dabei in einem gewissen Winkelabstand zum radialen Austritt des Fadens aus dem Spindelrotor, vorzugsweise in einem Winkelabstand zwischen 20o und 120o.The thread guide eyelet attached to the balloon limiter is attached in particular to the upper edge region of the balloon limiter which is just touched by the thread. The thread guide eyelet is at a certain angular distance from the radial exit of the thread from the spindle rotor, preferably at an angular distance between 20 o and 120 o .

Die Fadenführungsöse ist in Umfangsrichtung des Ballonbegrenzer-Innenmantels mit einer länglichen Öffnung ausgestattet, die es dem Faden erlaubt, innerhalb dieser Länge frei zu schwingen. Das ist immer dann der Fall, wenn sich der Fadenballon infolge veränderter innerer oder äußerer Fadenspannungen an diese Spannungsänderungen anpassen muß. Der Faden bzw. Fadenballon kann im Rahmen der länglichen Fadenführungsöse entsprechend der erforderlichen Spannungsanpassung pendeln. Die Umfangslänge der Fadenführungsöse soll in allen Arbeitspositionen etwa +/- 15o zur eingestellten Winkellage der Fadenführungsösenposition betragen. Die Fadenführungsöse ist vorzugsweise so ausgeführt, daß der Faden je nach Drehrichtung der Spindel selbstätig in die Fadenfürungsöse eingefädelt wird. Zur Berücksichtigung entgegengesetzter Spindellaufrichtungen sind am Umfang des Ballonbegrenzers zwei sich diametral gegenüberliegende Fadenführungsösen vorgesehen. Damit wird gleichzeitig der Wuchtzustand des mitrotierenden Ballonbegrenzers aufrechterhalten.The thread guide eyelet is equipped with an elongated opening in the circumferential direction of the balloon limiter inner jacket, which allows the thread to swing freely within this length. This is always the case when the thread balloon has to adapt to these changes in tension as a result of changed internal or external thread tensions. The thread or thread balloon can swing in the frame of the elongated thread guide eyelet according to the required tension adjustment. The circumferential length of the thread guide eyelet should be about +/- 15 o in all working positions set angular position of the thread guide eyelet position. The thread guide eyelet is preferably designed so that the thread is automatically threaded into the thread guide eyelet depending on the direction of rotation of the spindle. To take account of opposite spindle running directions, two diametrically opposite thread guide eyes are provided on the circumference of the balloon limiter. The balancing state of the rotating balloon limiter is maintained at the same time.

Konstruktiv sind die Fadenführungsösen am Ballonbegrenzer so angebracht, daß sie zwischen 20o und 120o relativ zum radialen Austritt des Fadens aus dem Spindelrotor verstellt werden können.In terms of construction, the thread guide eyes are attached to the balloon limiter so that they can be adjusted between 20 o and 120 o relative to the radial exit of the thread from the spindle rotor.

Wenn die Fadenführungsösen fest an dem oberen Ballonbegrenzerrand angebracht sind, kann ein Teilbereich des Ballonbegrenzers gegenüber dem radialen Austritt des Fadens am Spindelrotor verdreht werden, um den angestrebten Winkelabstand α zu erreichen.If the thread guide eyelets are firmly attached to the upper balloon limiter edge, a portion of the balloon limiter can be rotated relative to the radial outlet of the thread on the spindle rotor in order to achieve the desired angular distance α.

Das mit der Erfindung angestrebte Ziel einer betriebssicheren Fadenspeicherung im Fadenballon wird nur dann erreicht, wenn sichergestellt ist, daß der Faden nicht zur Umschlingung des Spulentopfes neigt, indem ohne Zwangsführung des Fadens durch die in einem bestimmten Winkelabstand zum radialen Austritt des Fadens aus dem Spindelrotor am oberen Ballonbegrenzerrand angebrachte Fadenführungsöse eine Fadenspeicherung erreicht wird.The aim of the invention of a reliable thread storage in the thread balloon is only achieved if it is ensured that the thread does not tend to wrap around the bobbin by, without positive guidance of the thread by a certain angular distance to the radial exit of the thread from the spindle rotor on upper balloon limiter attached thread guide eye thread storage is achieved.

Figur 1 zeigt repräsentativ für eine Zwirnmaschine einen Teil einer Spindelbank 1, in der eine Spindellagerhülse 2 stationär gelagert ist. In der Spindellagerhülse 2 ist mittels Lagern 3 und 4 ein Spindelschaft 5 drehbar gelagert, an dessen unterem Ende ein in Richtung des Pfeiles f1 rotierend antreibbarer Spindelwirtel 6 befestigt ist. An das obere Ende des Spindelschaftes 5 schließt sich die Spindelhohlachse 7 an, an deren unterem Ende ein mit einem radial verlaufenden Fadenleitkanal 9 versehener Drehteller 8 befestigt ist. Der Drehteller 8 ist von einem Ring 10 umgeben, der einen an den Fadenleitkanal anschließenden, zuerst radial und daran anschließend axial nach oben verlaufenden Umlenkkanal 11 aufweist. An den Ring 10 schließt sich ein nach oben erstreckender Ballonbegrenzer 12 an, der in seinem oberen Bereich, vorzugsweise am oberen Ballonbegrenzerrand, im Winkelabstand von der radialen Austrittsöffnung des Fadenleitkanals 9 eine Fadenführungsöse 13 trägt. An den unteren Rand des Ballonbegrenzers 12 schließt sich im wesentlichen flanschartig ein Ringkörper 14 an. In des untere Ende der Spindelhohlachse 7 ist ein Fadenumlenkkörper 15 eingesetzt, der einen Fadenumlenkkanal 16 mit einem axialen Kanalabschnitt und einem in den Fadenleitkanal mündenden radialen Kanalabschnitt aufweist.Figure 1 shows, representative of a twisting machine, part of a spindle bench 1, in which a spindle bearing sleeve 2 is mounted in a stationary manner. A spindle shaft 5 is rotatably mounted in the spindle bearing sleeve 2 by means of bearings 3 and 4, on the lower end of which a spindle whorl 6 which can be driven in the direction of arrow f1 is fastened. At the upper end of the spindle shaft 5 there is the spindle hollow axis 7, at the lower end of which a turntable 8 provided with a radial thread guide channel 9 is fastened. The turntable 8 is surrounded by a ring 10 which has a deflecting duct 11 which adjoins the thread guiding duct and runs first radially and then axially upwards. Connected to the ring 10 is an upwardly extending balloon limiter 12, which in its upper region, preferably at the upper balloon limiter edge, carries a thread guide eyelet 13 at an angular distance from the radial outlet opening of the thread guide channel 9. An annular body 14 adjoins the lower edge of the balloon limiter 12 essentially in the manner of a flange. In the lower end of the spindle hollow axis 7, a thread deflecting body 15 is inserted, which has a thread deflecting channel 16 with an axial channel section and a radial channel section opening into the thread guiding channel.

Auf der Spindellagerhülse 2 ist ein entgegengesetzt zum Spindelwirtel 6 in Richtung des Pfeiles f2 antreibbarer Spulenträgerwirtel 17 drehbar gelagert. In das obere, hülsenförmig gestaltete Ende des Spulenträgerwirtels 17 sind sich entlang einer Kreisbahn erstreckende Mitnehmer-Magnete 18 eingesetzt, die unterhalb des Drehtellers 8 in einen Ringraum ragen.On the spindle bearing sleeve 2, a coil carrier shaft 17 which can be driven in the opposite direction to the spindle shaft 6 in the direction of the arrow f2 is rotatably mounted. In the upper, sleeve-shaped end of the coil carrier whorl 17, entraining magnets 18 are inserted along a circular path, which are below the Protect the turntable 8 in an annular space.

Auf der Spindelhohlachse 7 ist mittels Lagern 19 und 20 eine hülsenförmige Spulenträgernabe 21 drehbar gelagert, die an ihrem unteren Ende einen beispielsweise abgestuften Spulenträgerboden 22 aufweist, der an seinem Außenumfang einen Spulenträger-Schutztopf 25 trägt. An der Unterseite des Spulenträgerbodens 22 sind den Mitnehmer-Magneten 18 gegenüberliegende Gegenmagnete 18.1 befestigt, die, bezogen auf die Mitnehmer-Magnete 18, derart polarisiert sind, daß bei rotierendem Spulenträgerwirtel 17 auch der aus Spulenträgernabe 21, Spulenträgerboden 22 und Schutztopf 25 bestehende Spulenträger in der gleichen Drehrichtung angetrieben wird. In das obere Ende der Spulenträgernabe 21 ist konzentrisch zur Spindelhohlachse 7 ein Fadeneinlaufrohr 23 eingesetzt. Auf die Spulenträgernabe 21 ist eine Vorlagespule 24 derart aufgeschoben und auf dem abgestuften Spulenträgerboden 22 abgestellt, daß die Vorlagespule 24 bei rotierendem Spulenträger 21, 22 schlupffrei ebenfalls in Drehung versetzt wird.On the spindle hollow axis 7, a sleeve-shaped coil carrier hub 21 is rotatably mounted by means of bearings 19 and 20, which has, for example, a stepped coil carrier base 22 at its lower end, which carries a coil carrier protective pot 25 on its outer circumference. On the underside of the coil carrier base 22, opposing magnets 18.1 are fastened to the driver magnets 18, which are polarized in relation to the driver magnets 18 in such a way that when the coil carrier whorl 17 rotates, the coil carrier consisting of coil carrier hub 21, coil carrier base 22 and protective pot 25 also driven in the same direction. In the upper end of the bobbin hub 21, a thread inlet tube 23 is inserted concentrically to the hollow spindle axis 7. A supply spool 24 is pushed onto the spool support hub 21 and placed on the stepped spool support base 22 in such a way that the supply spool 24 is also set in rotation without slippage when the spool support 21, 22 is rotating.

Bei laufender Spindel wird der Faden F nach oben von der Vorlagespule 24 abgezogen und durch das Fadeneinlaufrohr 23 und die Spindelhohlachse 7 zuerst nach unten und dann durch den radialen Fadenleitkanal 9 radial nach außen und dann wiederum zwischen dem Spulenträgerschutztopf 25 und dem Ballonbegrenzer 12 nach oben zu einer in der Verlängerung der Spindelhohlachse liegenden Fadenführeröse 26 (Fig. 2) geführt, von wo aus der Faden dann zu einem nicht dargestellten Aufwickelaggregat verläuft. Um eine ausreichende Fadenspeicherung zu erreichen, ist der Faden durch die Fadenführungsöse 13 hindurchgeführt, die in einem geeigneten Winkelabstand von der Austrittsöffnung des radial gerichteten Fadenleitkanals 9 bzw. des Fadenumlenkkanals 11 liegt.With the spindle running, the thread F is pulled upwards from the supply spool 24 and first downwards through the thread inlet tube 23 and the spindle hollow axis 7 and then radially outwards through the radial thread guide channel 9 and then again between the spool support pot 25 and the balloon limiter 12 a thread guide eyelet 26 (FIG. 2) lying in the extension of the hollow spindle axis, from where the thread then runs to a winding unit (not shown). Adequate thread storage to achieve, the thread is passed through the thread guide eyelet 13, which lies at a suitable angular distance from the outlet opening of the radially directed thread guide channel 9 or the thread deflecting channel 11.

Vorzugsweise sind jeweils zwei sich diametral gegenüberliegende Fadenführungsösen 13 vorgesehen, um Unwuchten zu vermeiden und einen gleichmäßigen Lauf des rotierenden Ballonbegrenzers zu gewährleisten. Das Vorhandensein von zwei sich diametral gegenüberliegenden Fadenführungen ermöglicht auch die erfindungsgemäße Verfahrensweise in beiden Drehrichtungen des Ballonbegrenzers 12 einerseits bzw. des in Figur 2 durch den Spulenträgertopf 25 repräsentierten Spulenträgers.Two diametrically opposite thread guide eyes 13 are preferably provided in order to avoid unbalance and to ensure a smooth running of the rotating balloon limiter. The presence of two diametrically opposed thread guides also enables the procedure according to the invention in both directions of rotation of the balloon limiter 12 on the one hand or of the bobbin holder represented in FIG. 2 by the bobbin holder pot 25.

Aus der perspektivischen Darstellung gemäß Fig. 2 mit teilweise weggebrochenem Ballonbegrenzer 12 ist der teilweise spiralförmige Verlauf des Fadens entlang der Ballonbegrenzerinnwand zwischen dem Austritt aus dem Fadenumlenkkanal 11 und der Fadenführungsöse 13 ersichtlich. Die Innenwand des in Richtung des Pfeiles f1 rotierenden Ballonbegrenzers 12 wird als Speicherzone genutzt, so daß auch in der Anlaufphase der Spindel keine Fadeneinschnürung um den entgegengesetzt in Richtung des Pfeiles f1 rotierenden Spulentopfes 25 erfolgt. In Abhängigkeit von den Laufbewegungen der Spindel und dem zu verarbeitenden Fadenmaterial liegt die Fadenführungsöse 13 vorzugsweise in einem Winkel α zwischen 20o und 120o im Abstand von der Austrittsöffnung des Fadenumlenkkanals 11.From the perspective view according to FIG. 2 with the balloon limiter 12 partially broken away, the partially spiral course of the thread along the inner wall of the balloon limiter between the outlet from the thread deflection channel 11 and the thread guide eyelet 13 can be seen. The inner wall of the balloon limiter 12 rotating in the direction of arrow f1 is used as a storage zone, so that even in the start-up phase of the spindle there is no thread constriction around the bobbin 25 rotating in the direction of arrow f1. Depending on the running movements of the spindle and the thread material to be processed, the thread guide eyelet 13 is preferably at an angle α between 20 o and 120 o at a distance from the outlet opening of the thread deflection channel 11.

In Figur 2 ist der angesprochene Winkelabstand durch den Winkel α repräsentiert, und zwar bezogen auf die durch die x-Koordinate definierte Axialebene, in der der Fadenumlenkkanal 11 liegt, einerseits und die Durchlaufstelle des Fadens 11 durch die Fadenführungsöse 13 andererseits.In Figure 2, the mentioned angular distance is represented by the angle α, namely based on the axial plane defined by the x coordinate, in which the thread deflecting channel 11 lies, on the one hand and the passage point of the thread 11 through the thread guide eyelet 13 on the other hand.

Die Fadenführungsöse 13 hat in Umfangsrichtung des Ballonbegrenzers 12 eine längliche Form, die es dem Faden F erlaubt, innerhalb dieser Öffnungslänge frei zu schwingen, so daß der Fadenballon sich den garn- und ablaufabhängigen Fadenspannungen anpassen kann. Die Fadenführungsöse 13 hat in Umfangsrichtung vorzugsweise eine Umfangslänge entsprechend +/- 15o zu der zentralen bzw. mittleren Winkellage der Fadenführungsöse 13 relativ zum Fadenumlenkkanal 11.The thread guide eyelet 13 has an elongated shape in the circumferential direction of the balloon limiter 12, which allows the thread F to oscillate freely within this opening length, so that the thread balloon can adapt to the yarn and sequence-dependent thread tensions. The yarn guide eyelet 13 has in the circumferential direction preferably have a circumferential length corresponding to +/- 15 o to the central or middle position of the yarn guide eyelet 13 angle relative to Fadenumlenkkanal. 11

Gemäß Figur 2 sind die sich diametral gegenüberliegenden Fadenführungsösen 13 unverstellbar an dem oberen Rand des Ballonbegrenzers 12 angebracht. Um die oben beschriebene, optimale Winkellage der jeweiligen Fadenführungsöse 13 relativ zum Fadenumlenkkanal 11 einstellen zu können, kann erfindungsgemäß vorgesehen sein, den Ballonbegrenzer 12 oder zumindest einen Teilbereich des Ballonbegrenzers relativ zum Fadenumlenkkanal 11 zu verstellen bzw. zu verdrehen.According to FIG. 2, the diametrically opposite thread guide eyelets 13 are attached to the upper edge of the balloon limiter 12 in an unadjustable manner. In order to be able to adjust the optimum angular position of the respective thread guide eyelet 13 described above relative to the thread deflecting channel 11, provision can be made according to the invention to adjust or twist the balloon limiter 12 or at least a portion of the balloon limiter relative to the thread deflecting channel 11.

Figur 2 deutet an bzw. läßt erkennen, daß bei fehlender Fadenführungsöse 13 am oberen mitrotierenden Rand des Ballonbegrenzers 12 sehr schnell eine unerwünschte Umschlingung des Fadens um den inneren Spulentopf 25 stattfinden könnte, was dann, wie bereits oben gesagt, durch den Seilreibungseffekt zu einem Fadenbruch führen würde.Figure 2 indicates or shows that if there is no thread guide eyelet 13 on the upper, co-rotating edge of the balloon limiter 12, an unwanted wrap of the thread around the inner bobbin 25 could very quickly take place, which, as already mentioned above, would result in a thread breakage due to the rope friction effect would lead.

Figur 3 zeigt eine Ausführungsform einer von Hand einfädelbaren Fadenführungsöse 13 in Form eines Bügels 27, der mittels einer elastisch verformbaren Halterung 50 federnd in den Ballonbegrenzer 12 eingespannt ist. Das freie, schnabelförmige Bügelende kann damit bei rotierendem Ballonbegrenzer 12 infolge der Zentrifugalkraft in eine im Ballonbegrenzer 12 angebrachte Öffnung 12.1 eintreten. Auf diese Weise ist eine geschlossene Fadenführungsöse 13 gebildet, die selbst bei in Umfangsrichtung zwischen den Extremstellungen F1 und F2 schwingendem Faden F ein Ausfädeln des Fadens aus der Fadenführungsöse 13 verhindert.Figure 3 shows an embodiment of a hand threadable eyelet 13 in the form of a bracket 27 which is resiliently clamped in the balloon limiter 12 by means of an elastically deformable holder 50. With the balloon limiter 12 rotating, the free, beak-shaped bow end can therefore enter an opening 12.1 made in the balloon limiter 12 as a result of the centrifugal force. In this way, a closed thread guide eyelet 13 is formed, which prevents the thread from being pulled out of the thread guide eyelet 13 even when the thread F oscillates in the circumferential direction between the extreme positions F1 and F2.

Die Figuren 4 bis 6 zeigen eine in Richtung des Doppelpfeiles f3 relativ zum Ballonbegrenzer 12 verstellbare, ebenfalls längliche Fadenführungsöse 113, die an einem am oberen Ballonbegrenzerrand in verschiedenen Stellungen festklemmbaren Klemmkörper 114 angebracht ist. Der Ballonbegrenzer kann als Arretierungselemente beispielsweise Einrastöffnungen 12.2 für an dem Klemmkörper 114 angebrachte Klemmnasen 114.1 aufweisen. Die Fadenführungsöse 113 wird durch einen bügelförmigen Keramikkörper 115 gebildet, der mit einem Ende entsprechend der Ausführungsform von Figur 3 elastisch an dem Klemmkörper 114 befestigt sein kann, während das andere Ende beispielsweise schnabelförmig ausgebildet sein kann und zur Bildung einer geschlossenen Öse mit einem gegenüberliegenden, vorzugsweise ebenfalls schnabelförmig ausgebildeten Gegenelement 116 überlappend zusammenwirkt.FIGS. 4 to 6 show a likewise elongate thread guide eyelet 113 which is adjustable in the direction of the double arrow f3 relative to the balloon limiter 12 and is attached to a clamping body 114 which can be clamped in various positions on the upper balloon limiter edge. The balloon limiter can, for example, have locking openings 12.2 as locking elements for clamping lugs 114.1 attached to the clamping body 114. The thread guide eyelet 113 is formed by a bow-shaped ceramic body 115, which can be elastically fastened to the clamping body 114 with one end in accordance with the embodiment of FIG. 3, while the other end can be, for example, beak-shaped and to form a closed eyelet with an opposite, preferably also beak-shaped counter element 116 cooperates overlapping.

Zumindest die von dem Faden bestrichenen Teile der Fadenführungsöse 13, 113 bzw. 213 bestehen aus einen verschleißfesten Material oder haben eine Beschichtung aus verschleißfestem Material.At least the parts of the thread guide eyelets 13, 113 and 213 which are covered by the thread consist of a wear-resistant material or have a coating of wear-resistant material.

Die Figuren 7 bis 9 zeigen eine bei Spindelstillstand selbsttätig öffnende, ebenfalls längliche Fadenführungsöse 213 in Form eines Bügels 215, der um die Schwenkachse 214 verschwenkbar an einem Trägerkörper 216 angelenkt ist, der in Richtung des Doppelpfeiles f3 verstellbar am oberen Rand des Ballonbegrenzers 12 befestigt ist. An dem sich im Bereich der Schwenkachse 214 befindenden Bügelende kann beispielsweise ein sich an dem Trägerkörper 216 abstützendes Federelement 217 angreifen, von dem der Bügel 215 in die in Figur 7 dargestellte Öffnungsstellung verschwenkt bzw. gedrückt wird. Bei rotierendem Ballonbegrenzer 12 wird dieser Bügel 215 durch Zentrifugalkraft in die in Figur 8 dargestellte Schließstellung bewegt, um damit eine geschlossene Fadenführungsöse 213 für den Faden F zu bilden.FIGS. 7 to 9 show an automatically elongated thread guide eyelet 213 in the form of a bracket 215, which automatically opens when the spindle is at a standstill, and which is pivotably pivoted about the pivot axis 214 on a carrier body 216, which is adjustably attached to the upper edge of the balloon limiter 12 in the direction of the double arrow f3 . A spring element 217, which is supported on the carrier body 216 and by which the bracket 215 is pivoted or pressed into the open position shown in FIG. 7, can act on the bracket end located in the region of the pivot axis 214. When the balloon limiter 12 rotates, this bracket 215 is moved by centrifugal force into the closed position shown in FIG. 8 in order to form a closed thread guide eyelet 213 for the thread F.

Zum Verstellen des Trägerkörpers 216 ist im oberen Ballonbegrenzerbereich eine Sicke 12.3 als Aufnahme für den Trägerkörper 216 angebracht. Ein Teilumfang des Ballonbegrenzers 12 ist im Sickenbereich mit einem Langloch 218 versehen. Der Trägerkörper 216 ist über zwei Stehbolzen 219 an einem Drehring 220 befestigt, der um den oberen Rand des Ballonbegrenzers 12 herumgeführt ist. Auf diese Weise können sich gemäß der obigen Beschreibung diametral gegenüberliegende Fadenführungen 213 mit Hilfe des Ringes 220 gemeinsam verstellt werden, wobei geeignete Rastelemente etwa gemäß den Ausführungsformen der Figuren 4 und 6 zum Feststellen bzw. Arretieren des Drehringes 220 vorgesehen sein können.To adjust the support body 216, a bead 12.3 is attached in the upper balloon limiter area as a receptacle for the support body 216. A partial circumference of the balloon limiter 12 is provided with an elongated hole 218 in the bead area. The carrier body 216 is fastened via two stud bolts 219 to a rotating ring 220 which is guided around the upper edge of the balloon limiter 12. In this way, according to the above description, diametrically opposed thread guides 213 can be adjusted together with the aid of the ring 220, suitable latching elements, for example in accordance with the embodiments in FIGS. 4 and 6, being able to be used to secure or lock the rotary ring 220.

Die erfindungsgemäße Verfahrensweise, das heißt die Verwendung einer am rotierenden Ballonbegrenzer angebrachten Fadenführungsöse ist auch bei einer Doppeldraht-Zwirnspindel (zweifache Drallerteilung) möglich, um nach dem Austreten des Fadens aus dem radialen Fadenleitkanal des Spindelrotors eine ausreichende Fadenreserve bzw. Fadenspeicherzone an der rotierenden Innenwand des Ballonbegrenzers aufzubauen. Die oben beschriebene, an dem rotierenden Ballonbegrenzer im oberen Ballonbegrenzerbereich angebrachte Fadenführungsöse kann für eine Doppeldraht-Zwirnspindel in der gleichen Weise verwirklicht sein, wie es in Verbindung mit den Figuren 1 bis 9 beschrieben ist.The procedure according to the invention, that is to say the use of a thread guide eyelet attached to the rotating balloon limiter, is also the case with one Double-wire twisting spindle (double twist distribution) possible in order to build up a sufficient thread reserve or thread storage zone on the rotating inner wall of the balloon limiter after the thread emerges from the radial thread guide channel of the spindle rotor. The thread guide eyelet described above, which is attached to the rotating balloon limiter in the upper balloon limiter region, can be implemented for a double-wire twisting spindle in the same way as is described in connection with FIGS. 1 to 9.

Gemäß Figur 11 sind die Fadenführungsösen 313, die die Form von Bügeln 315 haben, so angeordnet, daß die Öffnungen 314 zum Einfädeln des Fadens F den Austritten, d.h. Fadenaustrittsöffnungen 11 des dem Spindelrotor, bezogen auf die Drehrichtung f1 des Ballonbegrenzers 12 zugewandt sind. Diese Anordnung bedingt eine manuelle Fadeneinfädelung oder es ist eine zusätzliche Fadeneinfädelungseinrichtung erforderlich.According to Figure 11, the thread guide eyes 313, which have the shape of brackets 315, are arranged such that the openings 314 for threading the thread F the exits, i. Thread outlet openings 11 of the spindle rotor, facing the direction of rotation f1 of the balloon limiter 12. This arrangement requires manual threading or an additional threading device is required.

Bei der Ausführungsform gemäß Fig. 10 sind die beiden Fadenführungsösen 313, die ebenfalls die Form von Bügeln 315 haben, bezogen auf die Drehrichtung f4 des Ballonbegrenzers 12 so angeordnet, daß die Öffnungen 314 zum Einfädeln des Fadens F den Fadenaustrittsöffnungen 11 des Spindelrotors zugewandt sind, so daß beim Anlaufen der Spindel unabhängig von der Drehrichtung der Spindel bzw. des Ballonbegrenzers eine automatische Fadeneinfädelung erfolgt. Gemäß Fig. 10 rotiert der Spindelrotor in der Richtung des Pfeiles f4.In the embodiment according to FIG. 10, the two thread guide eyes 313, which also have the shape of brackets 315, are arranged with respect to the direction of rotation f4 of the balloon limiter 12 such that the openings 314 for threading the thread F face the thread outlet openings 11 of the spindle rotor, so that when the spindle starts, an automatic threading occurs regardless of the direction of rotation of the spindle or the balloon limiter. 10, the spindle rotor rotates in the direction of arrow f4.
