Abstract

A method for controlling a thread store on a spinning machine is proposed. When threads are being wound, it can happen, for example during the formation of conical bobbins, that more thread is delivered than is wound. The thread briefly in excess is picked up in the form of a thread loop by a jockey arm which engages transversely into the thread run and which is mounted pivotably. It is proposed, according to the invention that the jockey arm be loaded by a spring which loads it with increasing force when the thread loop decreases, and that, in the event of further deflection, the force of an additional elastic element acts on the jockey arm. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Steuern eines Fadenspeichers nach dem Oberbegriff des Anspruchs 1 sowie eine Spinnereivorrichtung gemäß dem Oberbegriff des Patentanspruchs 3. Insbesondere beim Aufwinden von konischen Spulen beispielsweise an Offenend-Rotorspinnmaschinen besteht das Problem, daß der mit konstanter Geschwindigkeit gelieferte Faden nicht mit konstanter Geschwindigkeit von der Spuleinrichtung auf eine Kreuzspule aufgewunden werden kann. Dies liegt bekanntermaßen daran, daß konische Spulen mit konstanter Geschwindigkeit umlaufen aber in Folge ihrer Konizität verschiedene Umfangslängen besitzen. Wird der Faden im Bereich des kleineren Durchmessers der konischen Spule verlegt, wird eine geringere Menge Faden aufgewunden, als wenn der Fadenführer den Faden im Bereich des großen Durchmessers der konischen Spule ablegt. Zur Lösung dieses Problems hat der Stand der Technik vorgeschlagen, Fadenspeicher einzusetzen, die dafür sorgen, daß der momentan nicht aufwindbare Faden zwischengespeichert wird, wobei dieser Fadenspeicher maximal gefüllt ist, wenn der Fadenführer den Faden im Bereich des kleinen Durchmessers der konischen Spule ablegt, während der Fadenspeicher die kleinste Fadenschlaufe speichert, wenn der Fadenführer im Bereich des großen Durchmessers der konischen Spule ablegt. Aus der DE 38 06 139 A1 ist beispielsweise bekannt, die Fadenspeicher als verschwenkbare Hebel auszubilden, die in Abhängigkeit von der Bewegung des Fadenführers zwangsgesteuert werden. Dazu ist ähnlich der Steuerung von Changierfadenführern eine über die Spinnmaschine reichende Changierstange vorgesehen. Vom Fadenspeicher wird der Faden quer zu seiner Laufrichtung zu einer Schlaufe geformt, die je nach Bedarf durch den verschwenkbaren Hebel größer oder kleiner gemacht wird.The present invention relates to a method for controlling a thread store according to the preamble of claim 1 and a spinning device according to the preamble of claim 3. Particularly when winding conical bobbins, for example on open-end rotor spinning machines, there is the problem that the thread supplied at constant speed is not included constant speed from the winding device can be wound onto a package. As is known, this is due to the fact that conical coils rotate at a constant speed but, due to their conicity, have different circumferential lengths. If the thread is laid in the area of the smaller diameter of the conical bobbin, a smaller amount of thread is wound up than if the thread guide deposits the thread in the area of the large diameter of the conical bobbin. In order to solve this problem, the prior art has proposed using thread stores which ensure that the thread which is currently unwindable is temporarily stored, this thread store being filled to the maximum when the thread guide passes the thread in the area of the small diameter of the conical bobbin, while the thread store stores the smallest thread loop when the thread guide deposits in the area of the large diameter of the conical bobbin. From DE 38 06 139 A1 it is known, for example, to design the thread stores as pivotable levers which are positively controlled depending on the movement of the thread guide. For this purpose, similar to the control of traversing thread guides, a traversing rod extending over the spinning machine is provided. From the thread storage device, the thread is formed into a loop transverse to its direction of travel, which is made larger or smaller as required by the pivotable lever.

Aus der DE-A 24 54 916 ist eine Spuleinrichtung für konische Kreuzspulen bekannt, bei der zur Aufnahme des zeitweise überschüssigen Fadens ein Fadenspeicher vorgesehen ist, der als federbelasteter Tänzerarm ausgebildet ist, der den Faden quer zur Fadenlaufrichtung auslenkt und unter Spannung hält. Bedingt durch die Feder 35 wird die Größe der Fadenschlaufe automatische dann größer, wenn mehr Faden angeliefert als aufgewunden wird. Umgekehrt ist der Fadenspeicher in der Lage, den Faden bei Bedarf auch wieder abzugeben. Eine Zwangssteuerung der Fadenschlaufe erfolgt nicht.From DE-A 24 54 916 a winding device for conical cross-wound bobbins is known, in which a thread store is provided for receiving the temporarily excess thread, which is designed as a spring-loaded dancer arm that deflects the thread transversely to the thread running direction and holds it under tension. Due to the spring 35, the size of the thread loop automatically becomes larger when more thread is delivered than is wound up. Conversely, the thread store is able to dispense the thread again if necessary. The thread loop is not positively controlled.

Von der Rotorspinnmaschine RU 14 der Firma Schubert & Salzer Maschinenfabrik Aktiengesellschaft in D 8070 Ingolstadt, ist ein ähnlicher Fadenspeicher bekannt, bei dem der Tänzerarm den Faden quer zur Spulenachse in Richtung zum Inneren der Maschine auslenkt. Die Kraft der auf den Tänzerarm wirkenden Feder kann mittels einer Verstelleinrichtung verändert werden, so daß an der Spulstelle Spulen mit verschiedener Fadenspannung hergestellt werden können. Derartige Fadenspeicher werden nicht nur für das Aufwinden von konischen Spulen benutzt, sondern ebenso, wenn beispielsweise während des Aufwindens gleichzeitig der Faden paraffiniert wird. Die dabei auftretenden Unregelmäßigkeiten in der Fadenspannung werden durch den Fadenspeicher ausreguliert.A similar thread store is known from the RU 14 rotor spinning machine from Schubert & Salzer Maschinenfabrik Aktiengesellschaft in D 8070 Ingolstadt, in which the dancer arm deflects the thread transverse to the bobbin axis towards the inside of the machine. The force of the spring acting on the dancer arm can be changed by means of an adjusting device, so that bobbins with different thread tension can be produced at the winding point. Such thread stores are used not only for the winding of conical bobbins, but also if, for example, the thread is waxed at the same time during winding. The resulting irregularities in the thread tension are corrected by the thread store.

Die bekannten Fadenspeicher haben den Nachteil, daß bei Veränderungen der Fadenspannung bzw. bei Verkleinerung der Fadenschlaufe über den Arbeitsbereich des Tänzerarms hinaus ein Kontakt zwischen Tänzerarm und Faden nicht immer gewährleistet ist. Wird beim Ansteigen der Fadenspannung der Tänzerarm schnell in Richtung seiner Endstellung des Arbeitsbereichs gebracht, kommt es vor, daß sich der Tänzerarm vom Faden ablöst und anschließend, bedingt durch die Feder, wieder auf diesen schlagartig zurückgeführt wird. Dies kann zu Fadenbrüchen führen.The known thread stores have the disadvantage that when the thread tension changes or the thread loop is reduced beyond the working area of the dancer arm, contact between the dancer arm and the thread is not always guaranteed. If the dancer arm is quickly brought in the direction of its end position of the working area when the thread tension rises, it happens that the dancer arm detaches from the thread and then, due to the spring, is suddenly returned to it. This can lead to thread breaks.

Aufgabe der vorliegenden Anmeldung ist es daher, die Nachteile des Standes der Technik zu vermeiden und einen Fadenspeicher für eine Spinnmaschine vorzuschlagen, der den Faden sicher führt, und Spannungsspitzen vermeidet, auch wenn der Tänzerarm über seinen normalen Arbeitsbereich hinaus ausgelenkt wird.It is therefore the object of the present application to avoid the disadvantages of the prior art and to propose a thread store for a spinning machine which guides the thread safely and avoids tension peaks, even if the dancer arm is deflected beyond its normal working range.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale der Patentansprüche 1 und 3 gelöst.This object is achieved by the features of claims 1 and 3.

Durch die erfindungsgemäße Ausgestaltung der Spinnereivorrichtung bzw. deren Fadenspeicher wird erreicht, daß beim Auftreten von Spannungsspitzen im Garn während der Fadenspeicher maximal ist, diese nicht zu Fadenbrüchen führen. Der Tänzerarm wird durch den sich streckenden Faden nicht von diesem abgehoben, sondern bleibt ständig mit ihm in Kontakt. Zusätzliche Belastungen des Fadens durch ein Zurückschlagen des Tänzerarms auf den Faden können dadurch vermieden werden. Besonders günstig ist es, wenn ein Anschlag vorgesehen ist, an dem der Tänzerarm anschlägt, bevor er seinen normalen Arbeitsbereich verläßt. An diesem Anschlag läßt sich besonders einfach ein zusätzliches elastisches Element anbringen, das dann seine Kraft auf den Tänzerarm überträgt. Besonders vorteilhaft ist es, wenn die Kraft des zusätzlichen elastischen Elements wesentlich größer ist, als die des ersten elastischen Elements. Dadurch wird sicher gewährleistet, daß die Spannungsspitzen des Garns abgefangen werden können. Bei einer besonders günstigen Ausführung des Fadenspeichers besitzt der Tänzerarm eine Verlängerung, die über seinen Drehpunkt hinausreicht, und mit der er mit dem Anschlag und dem zusätzlichen elastischen Element zusammenarbeitet. Ein weiterer Vorteil ist, daß beispielsweise eine automatische Wartungsvorichtung einer Spinnereimaschine an dieser Verlängerung den Tänzerarm bewegen kann. Dies ist z.B. beim Anspinnen an einer Offenend-Spinnmaschine erforderlich. Außerdem kann damit ein Auflegen des Tänzerarms auf den Faden genau gesteuert erfolgen. Bei einer weiteren günstigen Ausgestaltung der Erfindung ist das erste elastische Element über einen Schwenkarm befestigt. Durch Verschwenken des Schwenkarms wird die Vorspannung des ersten elastischen Elements verändert. Dadurch ist es möglich, die Spannung des Fadens einzustellen, mit der dieser auf die Spule aufgewunden werden soll. Eine besonders günstige Ausgestaltung erfährt die Erfindung, wenn die Schwenkarme beispielsweise einer Maschinenseite oder mehrerer Aufwindestationen an der Spinnereivorrichtung über eine Steuerstange in Verbindung stehen. Dadurch ist es möglich, die Fadenspannung gleichzeitig an allen oder mehreren Spulstellen einzustellen. Dazu ist es nur erforderlich, die Steuerstange beispielsweise am Maschinen-Endgestell zu verstellen.The inventive design of the spinning device or its thread storage means that when tension peaks occur in the yarn during the thread storage is maximum, these do not lead to thread breaks. The dancer arm is not lifted by the stretching thread, but remains in constant contact with it. Additional stresses on the thread due to the dancer arm striking back on the thread can thereby be avoided. It is particularly expedient if a stop is provided against which the dancer arm strikes before it leaves its normal working range. This stop is particularly easy to attach an additional elastic element, which then transmits its force to the dancer arm. It is particularly advantageous if the force of the additional elastic element is significant is larger than that of the first elastic member. This ensures that the tension peaks of the yarn can be intercepted. In a particularly favorable design of the thread store, the dancer arm has an extension which extends beyond its pivot point and with which it cooperates with the stop and the additional elastic element. Another advantage is that, for example, an automatic maintenance device of a spinning machine can move the dancer arm on this extension. This is necessary, for example, when spinning on an open-end spinning machine. In addition, the dancer arm can be placed on the thread in a precisely controlled manner. In a further advantageous embodiment of the invention, the first elastic element is fastened via a swivel arm. The pretension of the first elastic element is changed by pivoting the swivel arm. This makes it possible to adjust the tension of the thread with which it is to be wound onto the bobbin. The invention is particularly advantageous when the swivel arms are connected, for example, to a machine side or to several winding stations on the spinning device via a control rod. This makes it possible to set the thread tension simultaneously on all or more winding positions. It's just that necessary to adjust the control rod, for example on the machine end frame.

Besonders vorteilhaft ist es, wenn der Fadenspeicher so ausgebildet ist, daß der Tänzerarm seine Bewegung in einer Ebene ausführt, die horizontal ist. Dadurch wird erreicht, daß Einflüsse der Schwerkraft auf den Tänzerarm vermieden werden, wodurch die Fadenspannung des aufzuwindenden Fadens besser konstantgehalten werden kann. Durch diese Anordnung des Tänzerarmes muß dieser lediglich gegen seine Massenträgheit bewegt werden. Eine Bewegung entgegen der Schwerkraft, z.B. durch Anheben des Schwerpunktes bei einem in vertikaler Ebene sich bewegenden Tänzerarm, entfällt.It is particularly advantageous if the thread store is designed such that the dancer arm executes its movement in a plane that is horizontal. The effect of this is that gravity influences on the dancer arm are avoided, as a result of which the thread tension of the thread to be wound can be kept better constant. This arrangement of the dancer arm only has to be moved against its inertia. Movement against gravity, e.g. by lifting the center of gravity with a dancer arm moving in a vertical plane, is eliminated.

Der erfindungsgemäße Fadenspeicher 1 besitzt einen Tänzerarm 11, der drehbar auf einem Grundkörper 2 montiert ist. Am Grundkörper 2 ist drehbar ein Schwenkarm 3 befestigt. Vom Schwenkarm 3 zum Tänzerarm 11 ist ein elastisches Element 12 gespannt, durch das der Tänzerarm 11 mit einer Kraft beaufschlagt wird, die ihm gestattet entgegen der Spannung des Garns eine Garnschlaufe zu bilden. Der Schwenkarm 3 besitzt eine Nut 31, in die ein Steuerstift 71 der Steuerstange 7 eingreift (vgl. Figur 3). Am Grundkörper 2 ist der Anschlag 4 drehbar gelagert, der mittels des zusätzlichen elastischen Elements 41 in seiner in Figur 1 gezeigten Grundstellung gehalten wird. Der Tänzerarm 11 besitzt eine Verlängerung 13, mit der er in der Darstellung von Figur 1 an einem Stift 42 des Anschlags 4 anliegt. Der Verlauf des Garns erstreckt sich senkrecht zur Bildebene von Figur 4. Der Fadenspeicher 1 ist dabei mit seiner Ebene, die er in Figur 1 einnimmt, parallel zur Friktionswalze, mit deren Hilfe die konische Spule angetrieben wird, angeordnet. Figur 3 zeigt die Anordnung der Fadenspeicher 1 in der Spinnereivorrichtung nebeneinander, wobei sich rechts von der Steuerstange 7 die Maschine in die Tiefe ausbreitet. Im Gegensatz zum Tänzerarm der Figur der DE-OS 24 54 916, bei der der Tänzerarm parallel zur Spule die Fadenschlaufe bildet, wird sie vom Fadenspeicher 1 der Figur 1 senkrecht zur Achse der Spule gebildet.The thread store 1 according to the invention has a dancer arm 11 which is rotatably mounted on a base body 2. A swivel arm 3 is rotatably attached to the base body 2. An elastic element 12 is stretched from the swivel arm 3 to the dancer arm 11, by means of which a force is exerted on the dancer arm 11 which allows it to form a yarn loop against the tension of the yarn. The swivel arm 3 has a groove 31 into which a control pin 71 of the control rod 7 engages (cf. FIG. 3). The stop 4 is rotatably mounted on the base body 2 and is held in its basic position shown in FIG. 1 by means of the additional elastic element 41. The dancer arm 11 has an extension 13 with which it rests in the illustration of FIG. 1 on a pin 42 of the stop 4. The course of the yarn extends perpendicular to the image plane of Figure 4. The thread store 1 is arranged with its plane, which it occupies in Figure 1, parallel to the friction roller, with the help of which the conical bobbin is driven. Figure 3 shows the arrangement of the thread store 1 in the spinning device next to each other, wherein the machine spreads out to the right of the control rod 7. In contrast to the dancer arm of the figure of DE-OS 24 54 916, in which the dancer arm forms the thread loop parallel to the bobbin, it is formed by the thread store 1 of FIG. 1 perpendicular to the axis of the bobbin.

Der Tänzerarm 11 von Figur 1 ist in der einen Endstellung innerhalb seines Arbeitsbereichs dargestellt. Dies ist die Stellung, in der er am meisten ausgelenkt ist, ohne bereits von der Kraft des zusätzlichen elastischen Elements 41 beaufschlagt zu sein. Die Garnschlaufe wird vom Tänzerarm 11 dadurch gebildet bzw. vergrößert, daß er bei einer Betrachtung von Figur 1 nach rechts in Richtung des Pfeiles P schwenkt. Dabei wird die Kraft, die das erste elastische Element 12 auf ihn ausübt, kleiner, da es sich dabei um eine Feder mit einer Federkonstanten handelt. Der Faden läuft anders als beim Tänzerarm der DE-OS 24 54 916 nicht über Rollen, sondern wird durch den Haken 14 des Tänzerarms 11 geführt. Tritt nun der Fall ein, daß sich die Spannung des Fadens erhöht, obwohl der Tänzerarm 11 bereits in seiner in Figur 1 gezeigten Endstellung steht, wird durch den Faden eine zusätzliche Kraft entgegen der Pfeilrichtung P auf den Tänzerarm 11 ausgeübt. Dadurch schlägt er mit seiner Verlängerung 13 an den Stift 42 des Anschlags 4 an, wodurch dieser im uhrzeigersinn verdreht wird. Diese Verdrehung erfolgt gegen den Widerstand des zusätzlichen elastischen Elements 41, das als Feder ausgebildet ist. Dies alles hat zur Folge, daß der Tänzerarm 11 mit einer zusätzlichen Kraft beaufschlagt wird, die ihn in Pfeilrichtung P beaufschlagt. Durch diese zusätzliche Kraft wird erreicht, daß der Tänzerarm 11 nur sehr wenig über seinen Arbeitsbereich bewegt werden kann. Dadurch wird verhindert, daß der Faden in der Garnschlaufe ohne die Beaufschlagung durch den Tänzerarm 11 verbleibt. Dies ist wichtig, weil dadurch verhindert wird, daß Fadenbrüche entstehen.The dancer arm 11 of Figure 1 is shown in one end position within its working area. This is the position in which it is deflected most without the force of the additional elastic element 41 already being applied to it. The yarn loop is formed or enlarged by the dancer arm 11 by pivoting to the right in the direction of arrow P when viewed in FIG. 1. The force that the first elastic element 12 exerts on it becomes smaller since it is a spring with a spring constant. Unlike the dancer arm of DE-OS 24 54 916, the thread does not run over rollers, but is guided through the hook 14 of the dancer arm 11. If the situation arises that the tension of the thread increases, although the dancer arm 11 is already in its end position shown in FIG. 1, the thread exerts an additional force on the dancer arm 11 against the direction of the arrow P. He strikes with its extension 13 on the pin 42 of the stop 4, whereby this is turned clockwise. This rotation takes place against the resistance of the additional elastic element 41, which is designed as a spring. All of this has the result that the dancer arm 11 is acted upon by an additional force which acts on it in the direction of arrow P. This additional force means that the dancer arm 11 can only be moved very little over its working area. This prevents the thread from remaining in the yarn loop without being acted upon by the dancer arm 11. This is important because it prevents thread breaks from occurring.

Durch die Verlängerung 13 ist es auf einfache Weise möglich, daß ein automatisches Wartungsgerät den Tänzerarm 11 in eine gewünschte Stellung verschwenkt. So ist es z.B. bei Offenend-Vorrichtungen notwendig, daß während des Anspinnvorgangs der Tänzerarm 11 weiter entgegen der Pfeilrichtung P verschwenkt wird. Dies ist erforderlich, um zum Anspinnen den Faden rückführen zu können. Die Verlängerung 13 ermöglicht eine einfache Steuerung des Tänzerarms durch eine Wartungsvorrichtung, weil auf einfache Art, beispielsweise durch eine Stange die Verlängerung 13 in Richtung zum Schwenkarm 3 gedrückt werden kann.The extension 13 makes it possible in a simple manner for an automatic maintenance device to pivot the dancer arm 11 into a desired position. For example, in the case of open-end devices, it is necessary for the dancer arm 11 to be pivoted further against the direction of the arrow P during the piecing process. This is necessary in order to be able to return the thread for piecing. The extension 13 enables simple control of the dancer arm by a maintenance device, because the extension 13 can be pressed in a simple manner, for example by a rod, in the direction of the swivel arm 3.

Zum Verstellen der Federkraft der Feder 12 des ersten elastischen Elements wird ein Steuerstift 71 (vgl. auch Figur 3) in Richtung des Pfeiles F bewegt. Dadurch dreht sich der Schwenkarm 3 nach rechts, bzw. nach links, wodurch entsprechend die Feder 12 gedreht wird. Schwenkarm 3 ist drehbar, um die Befestigung 32 gelagert. Damit kann auf einfache Art die Fadenspannung des aufgewundenen Fadens eingestellt werden.To adjust the spring force of the spring 12 of the first elastic element, a control pin 71 (see also FIG. 3) is moved in the direction of the arrow F. As a result, the swivel arm 3 rotates to the right or to the left, as a result of which the spring 12 is rotated accordingly. Swivel arm 3 is rotatable about the mounting 32 mounted. The thread tension of the wound thread can thus be adjusted in a simple manner.

Figur 2 zeigt eine Seitenansicht des Fadenspeichers 1 von Figur 1. Beim Verschwenken des Tänzerarms entgegender der Pfeilrichtung P von Figur 1 schlägt die Verlängerung 13 am Stift 42 des Anschlags 4 an, wodurch dieser verdreht wird und gleichzeitg die Kraft des zusätzlichen elastischen Elements 41 auf den Tänzerarm 11 zur Wirkung bringt. Durch die großflächige Ausgestaltung der Verlängerung 13 ist eine besonders gute Steuerung des Tänzerarms 11 durch ein Wartungsgerät möglich.FIG. 2 shows a side view of the thread store 1 from FIG. 1. When the dancer arm is pivoted in the opposite direction of the arrow P from FIG Brings dancer arm 11 to effect. Due to the large-scale design of the extension 13, particularly good control of the dancer arm 11 by a maintenance device is possible.

Figur 3 zeigt zwei Fadenspeicher 1 in der Spinnereivorrichtung 8 montiert, von der Teile des Maschinengestells 81 sichtbar sind. Am Maschinengestell 81 ist auch die Steuerstange 7 gelagert, die zum Verstellen der Vorspannung der Feder 12 dient. Der Fadenspeicher A, im Bild von Figur 3 unten, ist ein Fadenspeicher, dessen Schwenkarm 3 sich in ähnlicher Lage befindet, wie derjenige von Figur 1. Die Feder 12 ist nur wenig gespannt. Durch Verschieben der Steuerstange 7 bei Figur 3, A in Richtung des Pfeiles G wird der Schwenkarm 3 in die Lage versetzt, wie er in Figur 3 B gezeigt ist. In dieser Stellung ist die Feder 12 maximal vorgespannt. Die Verschwenkung des Schwenkarms 3 erfolgt dadurch, daß der Steuerstift in der Nut 31 des Schwenkarms 3 verschoben wird, wobei der Steuerstift 71 lediglich in Pfeilrichtung G und entgegengesetzt dazu beweglich ist. Dadurch daß er keine Querbewegungen ausführen kann, ist der Schwenkarm 3 gezwungen um seine Befestigung 3 zu schwenken, wodurch es zu einer größeren oder kleineren Spannung in der Feder 13 kommt. Die Steuerstange 7 kann so ausgebildet sein, daß sie entlang einer ganzen Maschinenseite geführt wird, so daß alle daran angeschlossenen Fadenspeicher in der Vorspannung ihrer Feder 12 gleichzeitig verändert werden können.FIG. 3 shows two thread stores 1 mounted in the spinning device 8, from which parts of the machine frame 81 are visible. The control rod 7 is also mounted on the machine frame 81 and is used to adjust the preload of the spring 12. The thread store A, in the image of FIG. 3 below, is a thread store, the swivel arm 3 of which is similar Position is like that of Figure 1. The spring 12 is only slightly tensioned. By moving the control rod 7 in Figure 3, A in the direction of arrow G, the pivot arm 3 is placed in the position shown in Figure 3B. In this position, the spring 12 is maximally biased. The pivoting of the swivel arm 3 takes place in that the control pin is moved in the groove 31 of the swivel arm 3, the control pin 71 being movable only in the direction of arrow G and in the opposite direction. Because it cannot perform any transverse movements, the swivel arm 3 is forced to swivel its attachment 3, which results in a greater or lesser tension in the spring 13. The control rod 7 can be designed so that it is guided along an entire machine side, so that all thread stores connected to it can be changed in the bias of their spring 12 at the same time.

Die Fadenspeicher sind in der Spinnereivorrichtung 8 so angeordnet, daß deren Tänzerarme 11 ihre Bewegung in waagrechter Ebene ausführen. Durch diese Anordnung werden keine Einflüsse der Schwerkraft auf den vom Tänzerarm geführten Faden übertragen. Durch eine leichte Bauweise des Tänzerarmes 11 sind auch die Einflüsse auf den Faden, die durch Trägheit des Tänzerarmes entstehen, sehr gering.The thread stores are arranged in the spinning device 8 so that their dancer arms 11 execute their movement in a horizontal plane. With this arrangement, no influences of gravity are transmitted to the thread guided by the dancer arm. Due to the lightweight construction of the dancer arm 11, the influences on the thread, which arise due to the inertia of the dancer arm, are also very small.
