Description

Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben einer Spindel einer Doppeldrahtzwirn- oder Kabliermaschine gemäß dem Oberbegriff des Anspruches 1 sowie eine Doppeldrahtzwirn- oder Kabliermaschine gemäß dem Oberbegriff des Anspruches 8.The present invention relates to a method for operating a spindle of a double-twisting or cabling machine according to the preamble of claim 1 and to a double-twisting or cabling machine according to the preamble of claim 8.

Aus der DE 41 21 913 A1 ist es bekannt, die Fadenspannung eines Innenfadens und eines Außenfadens an einer Kordierspindel mittels Verstelleinrichtungen derart zu beeinflussen, dass die Fäden im Kablierpunkt mit gleicher Fadenspannung und Geschwindigkeit zusammengeführt werden. Dabei wird der Außenfaden mit einer Außenfadenbremse beeinflusst, deren Bremswirkung in Abhängigkeit von einer den Innenfaden beeinflussenden Innenfadenbremse gesteuert wird. Der Außenfaden wird von der Außenfadenbremse ausgehend zentrisch in die Kordierspindel eingeführt und tritt an einer rotierenden Speicherscheibe, die unterhalb des Zwirntellers an der Kordierspindel befestigt ist, radial aus. Der Außenfaden umschlingt die Speicherscheibe dabei zumindest teilweise, bevor der Faden über den äußeren Rand des Zwirntellers in den freien Fadenballon überführt wird.From the DE 41 21 913 A1 It is known to influence the thread tension of an inner thread and an outer thread on a Kordierspindel means of adjustment such that the threads are merged in Kablierpunkt with the same thread tension and speed. In this case, the outer thread is influenced by an outer thread brake whose braking effect is controlled as a function of an inner thread brake influencing the inner thread. The outer thread is inserted centrally from the outer thread brake into the Kordierspindel and occurs on a rotating storage disc, which is mounted below the twisting plate on the Kordierspindel radially. The outer thread wraps around the storage disc at least partially, before the thread is transferred over the outer edge of the twisting plate in the free thread balloon.

Als die die Form und den Durchmesser des freien Fadenballons im Wesentlichen beeinflussenden Größen sind der Durchmesser der Speicherscheibe sowie des Zwirntellers, die Ballonhöhe, die durch die Anordnung einer Ballonöse oder eines Ausgleichssystems, die den oberen Drehpunkt des Fadenballons bilden, der Titer sowie die Spindeldrehzahl zu nennen, deren aufeinander abgestimmte Optimierung einen sehr großen Aufwand erfordert, der oftmals gescheut wird. Dies ist insoweit von Nachteil, als dass die Ballonform die Energieaufnahme an jeder Spindel maßgeblich mitbestimmt, die Einflussnahmemöglichkeiten durch die genannten Parameter jedoch sehr gering ist. So geht eine Verringerung der Spindeldrehzahl mit einer Produktivitätseinbuße einher. Weiterhin beruht der Fadentiter auf dem durch den Betreiber der Textilmaschine vorgegebene zu verarbeitende Fadenmaterial. Die Einflussnahme auf die Ballonhöhe ist nur begrenzt möglich, da im weiteren Fadenlauf angeordnete Bauteile an der Textilmaschine den Gestaltungsspielraum einschränken.As the sizes substantially influencing the shape and diameter of the free filament balloon, the diameter of the disc and the cup, the height of the balloon constituted by the arrangement of a balloon eyelet or equalization system constituting the upper fulcrum of the filament balloon, the titer and the spindle speed are all too high call, their coordinated optimization requires a very large effort, which is often spared. This is disadvantageous in that the balloon shape absorbs energy at each Spindle decisively co-determined, the possibilities of influencing by the mentioned parameters, however, is very low. Thus, a reduction in the spindle speed is associated with a loss of productivity. Furthermore, the thread denier is based on the yarn material to be processed specified by the operator of the textile machine. The influence on the balloon height is limited possible because arranged in the further threadline components on the textile machine limit the scope of design.

Aus der gattungsbildenden EP 1 167 597 B1 ist eine Vorrichtung zum Kablieren bekannt, an welcher zur Regelung der Fadenspannung auf eine Speicherscheibe unterhalb des Zwirntellers verzichtet wird. Stattdessen wird die Fadenspannung im Wesentlichen durch einen mit der Spindel mitrotierenden Topf geregelt, der die Ausbildung eines freien Fadenballons bis auf einen Restballon weitgehend unterbindet. Bei dieser Vorrichtung fehlt der die Fadenspannung ausgleichende Einfluss der Speicherscheibe, um Lieferschwankungen auszugleichen. Stattdessen erfolgt die Zwangsführung des Fadenballons durch den Topf. Durch den Topf wird der um die Spindel rotierende Außenfaden in seiner radialen Ausdehnung beschränkt, so dass auf Grund der Reibung des Außenfadens an der Innenwand des Topfes die Fadenspannung reguliert wird, was dem Effekt der Verwendung einer Speicherscheibe entspricht. Der sich oberhalb des Topfes zwischen dessen Rand und der Fadenführeröse ausbildende freie Restfadenballon ist nicht geeignet, die Fadenspannung vor und nach der Spindel zu trennen, um Einflüsse bei der Lieferung auszugleichen. Durch den Einsatz des als Ballonbegrenzer ausgebildeten mitrotierenden Topfes, der die radialen Kräfte des Außenfadens aufnimmt, ist die Fadenspannung des Außenfadens geringer, als bei der aus der DE 41 21 913 A1 bekannten Kabliervorrichtung mit einer Speicherscheibe.From the generic EP 1 167 597 B1 is a device for cabling known, which is dispensed to control the thread tension on a storage disc below the twist plate. Instead, the thread tension is essentially controlled by a co-rotating with the spindle pot, which largely prevents the formation of a free thread balloon except for a residual balloon. In this device, the thread tension compensating influence of the storage disk is missing to compensate for delivery fluctuations. Instead, the forced guidance of the thread balloon takes place through the pot. By the pot, the outer thread rotating about the spindle is restricted in its radial extension, so that the thread tension is regulated due to the friction of the outer thread on the inner wall of the pot, which corresponds to the effect of using a storage disc. The above the pot between the edge and the thread guide eye forming free residual thread balloon is not suitable to separate the thread tension before and after the spindle to compensate for influences in the delivery. By using the designed as a balloon limiter mitrotierenden pot, which receives the radial forces of the outer thread, the thread tension of the outer thread is lower than in the from DE 41 21 913 A1 Known cabling with a storage disc.

Als nachteilig an der aus der EP 1 167 597 B1 bekannten Kabliervorrichtung erweist sich, dass der Einsatz des Topfes, der einem nicht unwesentlichen Verschleiß durch den rotierenden Außenfaden ausgesetzt ist, als rotierende Masse vom Spindelantrieb mitbewegt werden muss. Zudem verursacht die Luftreibung des Topfes zusätzliche Verluste, die durch den Spindelantrieb kompensiert werden müssen. Eine erzielbare Energieeinsparung, die durch den Verzicht auf die Ausbildung des freien Fadenballons erreicht werden kann, wird dadurch mehr als zunichte gemacht.As a disadvantage of the from EP 1 167 597 B1 Known cabling device proves that the use of the pot, which is exposed to a not insignificant wear by the rotating outer thread, must be moved as a rotating mass from the spindle drive. In addition, the air friction of the pot causes additional losses, which must be compensated by the spindle drive. An achievable energy savings, which can be achieved by dispensing with the formation of the free thread balloon, thereby more than negated.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Betreiben einer Doppeldrahtzwirn- oder Kabliermaschine bereitzustellen, welches sich durch eine reduzierte Energieaufnahme auszeichnet, sowie eine Doppeldrahtzwirn- oder Kabliermaschine zur Durchführung des Verfahrens vorzuschlagen.The invention has for its object to provide a method for operating a Doppeldrahtzwirn- or cabling, which is characterized by a reduced energy consumption, and to propose a Doppeldrahtzwirn- or cabling machine for performing the method.

Diese Aufgabe wird hinsichtlich des Verfahrens durch die kennzeichnenden Merkmale des Anspruches 1 gelöst sowie mit Bezug auf die Doppeldrahtzwirn- oder Kabliermaschine durch die kennzeichnenden Merkmale des Anspruches 8.This object is achieved in terms of the method by the characterizing features of claim 1 and with respect to the Doppeldrahtzwirn- or cabling machine by the characterizing features of claim 8

Vorteilhafte Ausführungsformen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche.Advantageous embodiments of the method according to the invention are the subject of the subclaims.

Gemäß Anspruch 1 wird vorgeschlagen, dass die Zufuhrgeschwindigkeit des Fadens so eingestellt wird, dass sich keine Speicherung einstellt und dass die Fadenspannung einen Wert annimmt, der den Durchmesser des die Spindel umkreisenden freien Fadenballons in Abhängigkeit von der Geometrie der Spindel minimiert. Der Wert für die Fadenspannung wird gemäß dem erfindungsgemäßen Verfahren derart eingestellt, dass die sich einstellende Fadenspannung größer wird, als die sich selbst einstellende Fadenspannung bei der Verwendung einer Speicherscheibe beziehungsweise auf Grund der Zwangsführung des Fadenballons in einem Topf. Durch das erfindungsgemäße Verfahren wird der Grundsatz, dass der freie Fadenballon eine eingeprägte, unumstößliche Geometrie aufweist, durchbrochen, so dass es keiner Speicherung wie bei der DE 41 21 913 A1 beziehungsweise keiner Zwangsführung durch einen Topf gemäß der EP 1 167 597 B1 bedarf, denen die erforderliche ausgleichende Funktion im Zwirn- oder Kabliersystem zukommt. Die erhöhte Fadenspannung vor dem Eintritt in die Führungsvorrichtung führt dazu, dass an dem Rand des Zwirntellers sich auf Grund des reduzierten Ballondurchmessers ein anderer Abwurfwinkel einstellt, als der Abwurfwinkel, der sich bei einer tangentialen Abhebung des Fadens von einer konventionellen Spindel mit einer Speicherscheibe unter Ausbildung eines freien Fadenballons beziehungsweise bei dem durch den Topf zwangsgeführten Fadenballon einstellt, dem die ausgleichende Funktion der Speicherscheibe bei einem freien Fadenballon zukommt. Da die Antriebsleistung unmittelbar vom Ballondurchmesser abhängig ist, führt die Reduzierung des Durchmessers des freien Fadenballons dazu, dass die zur Ausbildung und Aufrechterhaltung der Rotation des Fadenballons aufzubringende Energie sinkt, wodurch eine Einsparung der Energieaufnahme an der Spindel von 20% bis 30% erreichbar wird.According to claim 1, it is proposed that the feeding speed of the thread is set so that no storage is established and that the thread tension assumes a value which minimizes the diameter of the spindle surrounding the free filament balloon in dependence on the geometry of the spindle. The value for the thread tension is adjusted in accordance with the method according to the invention such that the adjusting thread tension becomes greater than that itself adjusting thread tension when using a storage disc or due to the positive guidance of the thread balloon in a pot. By the method according to the invention, the principle that the free thread balloon has an embossed, irrefutable geometry, broken so that it does not store as in the DE 41 21 913 A1 or no forced guidance by a pot according to the EP 1 167 597 B1 requires the required balancing function in the twisting or cabling system. The increased thread tension before entering the guide device causes a different discharge angle sets at the edge of the twisting dish due to the reduced balloon diameter, as the discharge angle, resulting in a tangential lift of the thread from a conventional spindle with a storage disc under training a free thread ballon or sets in the forcibly guided through the pot thread balloon, which plays the balancing function of the storage disc in a free thread balloon. Since the drive power is directly dependent on the balloon diameter, the reduction of the diameter of the free thread balloon causes the applied energy for the formation and maintenance of the rotation of the thread ballon drops, whereby a saving of power consumption on the spindle of 20% to 30% can be achieved.

Hierbei sollte der Fadenbedarf im Zwirn- oder Kablierpunkt ständig ermittelt und die Zuführgeschwindigkeit des Fadens an den ermittelten Fadenbedarf angepasst werden. Durch die kontinuierliche Anpassung der Zuführgeschwindigkeit werden Schwankungen in der Lieferung des Fadens, was zu einem Bruch des Fadens oder zu einem Zusammenfallen des Fadenballons führen kann, vermieden.Here, the thread requirement in the twisting or Kablierpunkt should be constantly determined and the feed rate of the thread to the determined thread requirement to be adjusted. The continuous adjustment of the feed rate avoids variations in the supply of the thread, which can lead to a breakage of the thread or to a collapse of the thread balloon.

Vorzugsweise kann als eine Stellgröße für die Zufuhrgeschwindigkeit die Fadenspannung verwendet werden, die vor oder nach der Ausbildung des Fadenballons an der Spindel bestimmt wird.Preferably, the thread tension determined before or after the formation of the thread balloon on the spindle can be used as a manipulated variable for the feed speed.

Alternativ kann als Stellgröße für die Zuführgeschwindigkeit die Leistungsaufnahme eines dem Antrieb der Spindel dienenden Spindelantriebes verwendet werden. Die Zuführgeschwindigkeit beeinflusst, wie bereits ausgeführt, den Durchmesser des freien Fadenballons, dessen Dimension maßgeblich für die Leistungsaufnahme des Spindelantriebes ist, die wiederum leicht zu erfassen und zu regeln ist.Alternatively, the power consumption of a spindle drive serving as a spindle drive can be used as a manipulated variable for the feed speed. The feed rate influences, as already stated, the diameter of the free thread balloon whose dimension is decisive for the power consumption of the spindle drive, which in turn is easy to detect and control.

Ebenfalls kann als Stellgröße für die Zuführgeschwindigkeit der Durchmesser des freien Fadenballons verwendet werden. Denkbar ist auch eine beliebige Kombination der genannten Stellgrößen, um die Zuführgeschwindigkeit möglichst präzise zu regeln.Also can be used as a control variable for the feed speed of the diameter of the free thread balloon. It is also conceivable any combination of said manipulated variables to regulate the feed rate as precisely as possible.

Dabei sind die Fadenspannung beziehungsweise die Leistungsaufnahme im Vergleich zur Ermittlung des Durchmessers des freien Fadenballons einfacher zu bestimmen. Auch eine Kombination mehrerer der genannten Stellgrößen kann sinnvoll sein, um den erforderlichen Wert für die Zuführgeschwindigkeit zur Minimierung des Fadenballons einzuhalten.In this case, the thread tension or the power consumption in comparison to determining the diameter of the free thread balloon are easier to determine. A combination of several of the above-mentioned control variables may be useful to maintain the required value for the feed rate to minimize the thread ballon.

Die erforderliche Überwachung der Stellgröße kann vorzugsweise elektronisch und/oder mechanisch durchgeführt werden.The required monitoring of the manipulated variable can preferably be carried out electronically and / or mechanically.

Gemäß Anspruch 8 wird eine Doppeldrahtzwirn- oder Kabliermaschine zur Durchführung des Verfahrens vorgeschlagen, die dadurch gekennzeichnet ist, dem Zwirnteller eine steuer- oder regelbare Vorrichtung zur Beeinflussung der Fadenspannung vorgeschaltet ist, durch die die Zufuhrgeschwindigkeit des Fadens so eingestellt wird, dass die Fadenspannung des in die Zuführvorrichtung eintretenden Fadens einen Wert annimmt, der den Durchmesser des die Spindel umkreisenden freien Fadenballons in Abhängigkeit von der Geometrie der Spindel minimiert. Der der Zuführvorrichtung zugeführte Faden wird durch die dem Spindelantrieb vorgeschaltete, steuer- oder regelbare Vorrichtung zur Beeinflussung der Fadenspannung mit einer Fadenspannung beaufschlagt, um den sich ausbildenden freien Fadenballon zu minimieren, was einen unmittelbaren positiven Einfluss auf den Energieverbrauch des Spindelantriebes hat.According to claim 8, a double twisting or cabling machine is proposed for carrying out the method, which is characterized, the twisting plate upstream of a controllable or controllable device for influencing the thread tension, through which the feed rate of Thread is adjusted so that the yarn tension of the thread entering the feeder assumes a value which minimizes the diameter of the spindle orbiting free yarn balloon, depending on the geometry of the spindle. The yarn fed to the feeder is loaded with a thread tension by the thread-tensioning device connected upstream of the spindle drive to control the thread tension in order to minimize the forming free thread balloon, which has a direct positive influence on the energy consumption of the spindle drive.

Hierzu sollte eine Steuerungseinrichtung vorgesehen sein, die zur Steuerung oder Regelung der Vorrichtung in Abhängigkeit von einer oder mehrerer Stellgrößen eingerichtet ist.For this purpose, a control device should be provided, which is set up to control or regulate the device as a function of one or more manipulated variables.

Insbesondere kann die Vorrichtung ein aktives Lieferwerk sein.In particular, the device may be an active delivery plant.

Alternativ kann die Vorrichtung als eine Bremse beziehungsweise als eine Kombination aus Bremse und aktivem Lieferwerk ausgebildet sein.Alternatively, the device may be designed as a brake or as a combination of brake and active delivery mechanism.

Als Ausgestaltungsvarianten des Lieferwerkes kann eine Galette, eine nacheilende Fächerscheibe oder eine Druckrolle vorgesehen sein.As a variant of the delivery work, a galette, a trailing fan disc or a pressure roller can be provided.

In der Fig. 1 ist in schematisierter Ansicht der Aufbau einer Arbeitsstelle 1 einer Kabliermaschine dargestellt, anhand der das erfindungsgemäße Verfahren erläutert wird. Die Arbeitsstelle 1 weist ein Gatter 4 auf, welches der Aufnahme mindestens einer ersten Vorlagespulen 7 dient, von der ein so genannter Außenfaden 5 abgezogen wird. Des Weiteren umfasst die Arbeitsstelle 1 eine Kablierspindel 2, die von einem Spindelantrieb 3 angetrieben wird. Bei dem Spindelantrieb 3 kann es sich um einen Motor handeln, der die Kablierspindel 2 direkt antreibt, oder um einen indirekten Antrieb, zum Beispiel um einen Riemenantrieb. Die Kablierspindel 2 trägt auf einem an der Kablierspindel 2 angeordneten Zwirnteller 8 eine zweite Vorlagespule 15, von der ein so genannter Innenfaden 16 über Kopf abgezogen wird, der oberhalb der Kablierspindel 2 einer Ballonöse oder einem Ausgleichssystem 9, im dargestellten Ausführungsbeispiel einem Cordregulator, zugeführt wird.In the Fig. 1 is shown in a schematic view of the structure of a job 1 a cabling, based on the method of the invention will be explained. The workstation 1 has a gate 4, which serves to receive at least one first feed bobbin 7, from which a so-called outer thread 5 is pulled off. Furthermore, the workstation 1 comprises a cabling spindle 2, which is driven by a spindle drive 3. The spindle drive 3 may be a motor which directly drives the cabling spindle 2 or an indirect drive, for example a belt drive. The Kablierspindel 2 carries on a arranged on the Kablierspindel 2 Zwinnnteller 8, a second feed bobbin 15, from which a so-called inner thread 16 is withdrawn overhead, which is above the Kablierspindel 2 a balloon eye or a balancing system 9, in the illustrated embodiment, a cord regulator supplied ,

Der von der ersten Vorlagespule 7 abgezogene Außenfaden 5 wird einer zwischen dem Gatter 4 und der Kablierspindel 2 im Fadenlauf angeordneten, regelbaren Fadenspannungsbeeinflussungsvorrichtung 6 zugeführt, mittels der die Fadenspannung variiert wird. Hierzu steht die Fadenspannungsbeeinflussungsvorrichtung 6 mit einer Steuerungseinrichtung 18 in Verbindung, die die Regelung der von der Vorrichtung 6 aufgebrachten Fadenspannung durchführt. Die Fadenspannungsbeeinflussungsvorrichtung 6 ist in Fadenabzugsrichtung gesehen dem Zwirnteller 8 vorgeschaltet. Anschließend durchläuft der Außenfaden 5 den Spindelantrieb 3 in der Drehachse und tritt unterhalb des Zwirntellers 8 aus dem Spindelantrieb 3 aus. Der Außenfaden 5 wird mittels einer Umlenkung tangential zum Zwirnteller 8 umgelenkt und läuft bis zum äußeren Rand des Zwirntellers 8. An dem Rand des Zwirntellers 8 wird der Außenfaden 5 nach oben umgelenkt, so dass der Außenfaden 5 entlang der Kablierspindel 2 unterThe withdrawn from the first feed bobbin 7 outer thread 5 is a arranged between the gate 4 and the Kablierspindel 2 arranged in the yarn path, controllable Fadenspannungsbeeinflussungsvorrichtung 6, by means of which the thread tension is varied. For this purpose, the thread tension influencing device 6 is connected to a control device 18, which carries out the regulation of the thread tension applied by the device 6. The yarn tension influencing device 6 is seen in the yarn withdrawal direction upstream of the twisting plate 8. The outer thread 5 then passes through the spindle drive 3 in the axis of rotation and exits from the spindle drive 3 below the twisting plate 8. The outer thread 5 is deflected by means of a deflection tangential to the twisting plate 8 and runs to the outer edge of the twisting plate 8. At the edge of the twisting plate 8, the outer thread 5 is deflected upward, so that the outer thread 5 along the Kablierspindel 2 below

Ausbildung eines freien Fadenballons B die Vorlagespule 15 umläuft. Die Ballonöse beziehungsweise das Ausgleichssystem 9 in denen der von der ersten Vorlagespule 7 abgezogene Außenfaden 5 und der von der zweiten Vorlagespule 15 abgezogene Innenfaden 16 zusammengeführt werden, bestimmt die Höhe des sich ausbildenden freien Fadenballons B. In der Ballonöse beziehungsweise dem Ausgleichssystem 9 befindet sich der Kablier- oder auch Cordierpunkt in dem die beiden Fäden 5, 16 zusammenlaufen und den Cordfaden 17 bilden.Forming a free thread balloon B, the supply spool 15 rotates. The balloon eye or the compensation system 9 in which the withdrawn from the first supply spool 7 outer thread 5 and withdrawn from the second supply spool 15 inner thread 16 are determined determines the height of the forming free thread balloon B. In the balloon eye or the equalization system 9 is the Cabling or Cordierpunkt in which the two threads 5, 16 converge and form the cord 17.

Oberhalb des Kablierpunktes ist eine Abzugsvorrichtung 10 angeordnet, mittels der der Cordfaden 17 abgezogen und über ein Ausgleichselement, wie beispielsweise einem Tänzer 11, einer Aufwickelvorrichtung 12 zugeführt wird. Die Aufwickelvorrichtung 12 weist eine Antriebswalze 13 und eine von der Antriebswalze 13 reibschlüssig angetriebene Spule 14 auf.Above the Kablierpunktes a take-off device 10 is arranged, withdrawn by means of the cord 17 and a compensating element, such as a dancer 11, a take-up device 12 is supplied. The take-up device 12 has a drive roller 13 and a coil 14 that is frictionally driven by the drive roller 13.

Der Fadenspannungsbeeinflussungsvorrichtung 6 kommt die Aufgabe zu, die Fadenspannung des Außenfadens 5 vor dem Zwirnteller 8 derart zu variieren, insbesondere zu erhöhen, dass eine Speicherscheibe, deren Einsatz zum Ausgleich von Unregelmäßigkeiten in der Fadenzufuhr im Allgemeinen üblich ist, entbehrlich wird. Die auf den Außenfaden 5 aufgebrachte regelbare Fadenspannung weist eine Größenordnung auf, die in Abhängigkeit von der Geometrie der Spindel 2 zu einer Minimierung des freien Fadenballons B führt. Erreicht wird dies durch eine veränderte Abwurfgeometrie des Außenfadens 5, die sich aus dem Verzicht auf die Speicherung ergibt. Während sich bei der Verwendung einer Speicherscheibe der Außenfaden nach deren zumindest teilweiser Umschlingung tangential von dieser abhebt, stellt sich durch den Verzicht auf die Nutzung der Speicherscheibe auf Grund der erhöhten Fadenspannung am äußeren Rand des Zwirntellers 8 ein anderer Abwurfwinkel des Außenfadens 5 ein, so dass der Durchmesser des sich ausbildenden freien Fadenballons B minimiert wird. Eine Fadenspeicherung ist bei dem erfindungsgemäßen Verfahren respektive der erfindungsgemäßen Vorrichtung im normalen Betrieb nicht vorgesehen beziehungsweise vorhanden.The yarn tension influencing device 6 has the task of varying the thread tension of the outer thread 5 in front of the twist-type disk 8 in such a way that, in particular, a storage disk whose use is generally customary for compensating for irregularities in the yarn feed is dispensable. The controllable thread tension applied to the outer thread 5 has an order of magnitude which, depending on the geometry of the spindle 2, leads to a minimization of the free thread balloon B. This is achieved by a modified release geometry of the outer thread 5, which results from the waiver of the storage. While in the use of a storage disk of the outer thread after their at least partial wrap tangentially from this stands out, is waiving the use of the storage disk due to the increased thread tension on the outer edge of the twisting plate 8, another release angle of the External thread 5, so that the diameter of the forming free thread balloon B is minimized. A thread storage is not provided or available in the method according to the invention or the device according to the invention in normal operation.

Als Fadenspannungsbeeinflussungsvorrichtung 6 kann beispielsweise eine elektronisch geregelte Bremse oder ein aktives Lieferwerk beziehungsweise eine Kombination der beiden Komponenten zum Einsatz kommen. Als Ausgestaltungsvarianten des Lieferwerkes sind beispielsweise eine Galette, eine Fächerscheibe oder eine Rolle mit korrespondierender Druckrolle möglich. Erfindungswesentlich ist die aktive, regelbare Beeinflussung der Fadenspannung, um den freien Fadenballon B mit einem möglichst konstanten, minimierten Durchmesser aufrechtzuerhalten. Die hierzu der Fadenspannungsbeeinflussungsvorrichtung 6 zugeordnete Steuerungsvorrichtung 18 verwendet als Stellgröße vorzugsweise die Spannung des Außenfadens 5 vor oder nach der Ausbildung des freien Fadenballons B. Alternativ oder zusätzlich kann als Stellgröße auch der Durchmesser des Fadenballons B oder die Leistungsaufnahme des Spindelantriebs 3 herangezogen werden, um Schwankungen von Liefergeschwindigkeiten, die zu Veränderungen der Fadenspannung führen, unmittelbar ausgleichen zu können.As a thread tension influencing device 6, for example, an electronically controlled brake or an active delivery mechanism or a combination of the two components can be used. As a variant of the delivery work, for example, a godet, a fan disc or a roller with a corresponding pressure roller are possible. Essential to the invention is the active, controllable influencing of the thread tension in order to maintain the free thread balloon B with as constant a minimized diameter as possible. The control device 18 assigned thereto for this purpose preferably uses the tension of the outer thread 5 before or after the formation of the free thread balloon B. Alternatively or additionally, the diameter of the thread balloon B or the power consumption of the spindle drive 3 can also be used as the manipulated variable to detect fluctuations of delivery speeds that lead to changes in the thread tension to be able to compensate immediately.

Die Überwachung der Fadenspannung zur Regelung der Fadenspannungsbeeinflussungsvorrichtung 6 kann elektronisch und/oder mechanisch erfolgen, beispielsweise durch eine Tänzerrolle oder eine konische Walze. Bei der Verwendung einer Tänzerrolle, die mit dem Außenfaden 5 in Verbindung steht, wird deren Auslenkung auf Grund der sich ändernden Fadenspannung erfasst, die als Stellgröße für die der Fadenspannungsbeeinflussungsvorrichtung 6 verwendet wird.The monitoring of the thread tension for controlling the thread tension influencing device 6 can be done electronically and / or mechanically, for example by a dancer roll or a conical roller. When using a dancer roll, which is in communication with the outer thread 5, the deflection of which is detected due to the changing thread tension, which is used as a control variable for the yarn tension influencing device 6.
