Description

Zwirne oder gezwirnte Fäden werden in der Regel in mehrstufigen Verfahren hergestellt, wobei die bekannten Verfahren und Vorrichtungen im wesentlichen folgende Einzelschritte bzw. Einzelmerkmale umfassen:Threads or twisted threads are usually produced in multi-stage processes, the known processes and devices essentially comprising the following individual steps or individual features:

1. Von einem Vorgarnvorrat werden Lunten mittels eines Streckwerks einer Ringspinnspindel zugeführt, auf der die Spinnfäden auf Spulenhülsen aufgewickelt werden. Diese Spulenkörper - im überwiegenden Fall Kopse - werden in einem zweiten Arbeitsschritt auf einer Spulmaschine zu Kreuzspulen umgespult. In einem dritten Arbeitsschritt werden zwei oder mehrere Kreuzspulen auf einer Fachmaschine aufgewunden. Die Fachkreuzspulen werden dann in einem vierten Arbeitsschritt beispielsweise einer Doppeldraht-Zwirnmaschine vorgelegt, um daraus einen fertigen Zwirn herzustellen.1. From a roving supply, slags are fed to a ring spinning spindle by means of a drafting device, on which the filaments are wound on bobbin tubes. These bobbins - in the main case copes - are rewound in a second step on a winder to form cross-wound bobbins. In a third step, two or more packages are wound on a specialist machine. In a fourth step, the specialist packages are then presented, for example, to a double-wire twisting machine in order to produce a finished twine.

Unter Ausschaltung des dritten Arbeitsschrittes können der Doppeldraht-Zwirnspindel auch direkt zwei Kreuzspulen der Spulmaschine zur Herstellung eines fertigen Zwirns vorgelegt werden.By turning off the third step, the double-wire twisting spindle can also two cross-wound bobbins of the winding machine for producing a finished thread are presented directly.

2. Es werden Spinnfäden nach dem Offenend-Spinnverfahren hergestellt und auf Hülsen zu Kreuzspulen aufgewunden. Fallweise werden auch zwei oder mehrere dieser Kreuzspulen in einem anschließenden Prozeß auf einer Fachmaschine zu einer rachkreuzspule umgewickelt. Die Kreuzspulen werden dann entweder zweifach oder im Fall der Fachkreuzspule als Einzelspule zur Verzwirnung einer Doppeldraht-Spindel vorgelegt.2. Spun threads are produced using the open-end spinning process and wound onto tubes to form packages. In some cases, two or more of these cross-wound bobbins are rewound in a subsequent process on a specialist machine to form a cross-wound bobbin. The cross-wound bobbins are then presented either twice or, in the case of the specialist cross-wound bobbin, as a single bobbin for twisting a double-wire spindle.

3. In dem Bestreben, die drei Prozesse Spinnen, Spulen und Zwirnen zu einem einzigen Kontinue-Prozess zusammenzulegen, wird auf eine Hohlspindel ein Garnkops aufgesteckt, der vorher z.B. auf einer üblichen Ringspinnspindel hergestellt worden ist. Ein von einem Vorgarnvorrat, beispielsweise Aufsteckgatter, kommendes Vorgarn durchläuft ein normales Streckwerk und wird zusammen mit dem Spinnfaden des vorher auf die Hohlspindel aufgesteckten Garnkopses in die Spindelhohlachse eingeführt. Das Garn der Garnspule wird bei den Spindelumdrehungen abgewickelt und läuft gemeinsam mit dem verstreckten Vorgarn durch die hohle Spindel zu einem Aufwickelwerk bzw. einer Spulstelle, wie es z.B. in "Eine neue Spinnzwirnmaschine" aus "Melliand-Textilberichte 12/1966", Seiten 1354 und 1355, beschrieben ist.3. In an effort to combine the three processes spinning, bobbin winding and twisting into a single continuous process, a yarn bobbin is attached to a hollow spindle, which previously e.g. has been produced on a conventional ring spinning spindle. A roving coming from a roving supply, for example a slip-on creel, passes through a normal drafting system and is inserted into the hollow spindle axis together with the spinning thread of the yarn bobbin previously placed on the hollow spindle. The yarn of the bobbin is unwound during the spindle revolutions and runs together with the drawn roving through the hollow spindle to a winding unit or a winding station, as e.g. in "A new spinning twister" from "Melliand textile reports 12/1966", pages 1354 and 1355.

4. Gemäß der DE 31 48874 A1 sind weiterhin Maschinen mit Streckwerk und Umwindespindeln bekannt, wobei die Fäden, vom Streckwerk kommend, durch die Achsen von Hohlspindeln gegebenenfalls mit Drallgeber über Liefer-Zylinder zu einem Aufwickelwerk geführt werden. Die Hohlspindeln müssen mit Kopsen oder parallel bewickelten Spulen in Spezialausführung bestückt werden. Die Fäden dieser Kopse oder Spulen sind nicht vergleichbar mit den Spulenkörpern gemäß den obigen Ziffern 1 und 2. Sie besitzen lediglich die Wicklungsart einer Kopswindung oder einer parallel bewickelten Scheibenspule, werden aber nicht auf Spinnmaschinen sondern auf entsprechenden Spulmaschinen hergestellt. Der Garnvorrat der Spulenkörper ist meist ein Filamentgarn. Durch Drehen der Hohlspindeln in vorgegebener Drehrichtung und eingestellter Drehzahlverhältnisse von Streckwerk, Lieferzylinder und Aufwindung erhält man ein Umwindegarn.4. According to DE 31 48874 A1 machines with drafting system and Winding spindles are known, the threads coming from the drafting system being guided through the axes of hollow spindles, optionally with a twister, to a winding unit via delivery cylinders. The hollow spindles must be equipped with copes or coils with a special design wound in parallel. The threads of these cops or bobbins are not comparable to the bobbins according to numbers 1 and 2 above. They only have the type of winding of a bobbin winding or a parallel-wound disc bobbin, but are not produced on spinning machines but on corresponding winding machines. The thread stock of the bobbin is usually a filament thread. By turning the hollow spindles in the specified direction of rotation and the set speed ratios of the drafting system, delivery cylinder and winding, you get a wrap yarn.

Obwohl das unter Ziffer 3 behandelte Verfahren den Anspruch stellt, die drei Prozesse Spinnen, Zwirnen und Spulen zu einem einzigen Kontinue-Prozess zusammenzulegen, ist es offensichtlich, daß diese Verfahrensweise aus den oben geschilderten Gründen dem gestellten Anspruch nicht voll gerecht wird, da es stets erforderlich ist, in einer ersten Verfahrensstufe, z.B. mittels einer üblichen Ringspinnmaschine, einen Spinnfaden herzustellen, der auf der Ringspinnmaschine zu einem Kops aufgewickelt wird, der dann erst in der unter Ziffer 3 beschriebenen Weise mit einem verstreckten Vorgarn verzwirnt wird. Der auf der Ringspinnmaschine hergestellte Garnkörper muß somit zwischen Maschinen mit fast gleicher Arbeits- und Funktionsweise hin- und hertransportiert werden, wobei insbesondere das Entnehmen und Wiedereinsetzen von Garnspulen einerseits und leeren Hülsen andererseits einen beträchtlichen Handhabungsaufwand bedingt, was insbesondere bei automatischen bzw. automatisierten Verfahrensabläufen zu einem hohen Aufwand bei der Automatisierung führen würde.Although the procedure described under point 3 claims to combine the three processes spinning, twisting and winding into a single continuity process, it is obvious that this procedure does not fully meet the claim for the reasons outlined above, since it always does it is necessary in a first process stage, for example by means of a conventional ring spinning machine, to produce a spinning thread which is wound on the ring spinning machine to form a cop, which is then only twisted with a drawn roving in the manner described under number 3. The package produced on the ring spinning machine must therefore be transported back and forth between machines with almost the same work and function are, whereby in particular the removal and reinsertion of yarn packages on the one hand and empty tubes on the other hand requires a considerable amount of handling, which would lead to a high level of automation effort, particularly in the case of automatic or automated process sequences.

5. In der DE 42 35 433 A1 ist ein Verfahren zur Herstellung eines gezwirnten Fadens beschrieben, bei dem in einem ersten Arbeitsschritt ein von einem Vorgarn-Vorrat abgezogenes und durch ein Streckwerk geführtes Vorgarn im Ringspinnverfahren versponnen und dabei auf einem auf eine Hohlspindel permanent angebrachten Garnträger zu einem Spinngarnkörper aufgewickelt wird; in einer zweiten Phase wird der Spinnprozeß unterbrochen und der zuvor zu dem Spinngarnkörper aufgewickelte Spinnfaden unter Ballonbildung von dem Spinngarnkörper wieder abgezogen und gemeinsam mit dem weiter von dem Vorgarnvorrat abgezogenen und im Streckwerk verstreckten Vorgarn durch die Hohlachse der Hohlspindel geführt und einem Aufwickelwerk zugeführt wird, wobei die Hohlspindel in Abhängigkeit von der Liefergeschwindigkeit der Friktionswalze des Aufwickelwerkes derart in Rotation versetzt wird, daß die Drehung des Spinnfadens wieder zurückgedreht wird.5. DE 42 35 433 A1 describes a method for producing a twisted thread, in which, in a first step, a roving drawn off from a roving supply and guided through a drafting device is spun in a ring spinning process and thereby permanently attached to a hollow spindle Yarn carrier is wound into a spun yarn body; In a second phase, the spinning process is interrupted and the spun thread previously wound up to form the spinning yarn body is drawn off from the spinning yarn body with balloon formation and, together with the roving further drawn from the roving stock and stretched in the drafting device, is guided through the hollow axis of the hollow spindle and fed to a winding unit, whereby the hollow spindle is set in rotation in dependence on the delivery speed of the friction roller of the winding unit in such a way that the rotation of the spinning thread is turned back again.

Ein grundsätzlich gleichartiges Verfahren geht auch aus der US 3 425 209 hervor.A fundamentally similar method is also apparent from US 3,425,209.

Bei diesen Verfahren arbeitet die Zwirnstufe mit einem Garnstrang, der Spinndrehung besitzt, und einen zweiten Garnstrang, der als Faserlunte zuläuft.In these processes, the twisting stage works with a strand of yarn that has spinning twist and a second strand of yarn that runs in as a fiber slub.

Ein in beiden Garnsträngen gleichmäßiger Zwirn wird bei diesem Verfahren dann hergestellt, wenn der Garnstrang mit der Spinndrehung entgegen der Spinnrichtung vollständig zurückgedreht und mit der vom Streckwerk kommenden Faserlunte gemeinsam in der Hohlachse verdrillt wird. Der aus der Faserlunte resultierende Garnstrang erhält bei diesem Verfahrensschritt keine Drehung. Wenn beide Garnstränge gleiche Drehung haben sollen, wie es von einem balancierten Zwirn erwartet wird, so kann dies immer nur dadurch geschehen, daß die den Spinnfaden des Spinngarnkörpers erteilte Spinndrehung während der zweiten Betriebsphase, das heißt während der Zwirnphase, wieder vollständig aufgelöst wird. Mit diesem Verfahren ist die Herstellung von Zwirnen mit nicht vollständig kompensierten Spinndrehungen nicht möglich.In this process, a twist that is uniform in both yarn strands is produced when the yarn strand is completely turned back with the spinning twist against the spinning direction and is twisted together in the hollow axis with the fiber sliver coming from the drafting device. The yarn strand resulting from the fiber sliver does not get any twist in this process step. If both twine strands are to have the same twist as is expected from a balanced twine, this can only ever be done by completely dissolving the spinning twist imparted to the spinning thread body during the second operating phase, i.e. during the twisting phase. With this process, the production of twisted yarns with incompletely compensated spinning twists is not possible.

Der Erfindung liegt die Aufgabe zugrunde, ein kombiniertes Spinn-Zwirn-Verfahren und eine entsprechende Vorrichtung zu schaffen, mit dem bzw. mit der es möglich ist, im fertigen Zwirn jedes beliebige Drehungsniveau zwischen den Einzelsträngen bzw. Einzelfäden einerseits und der Zwirndrehung andererseits zu erhalten. Zwirne dieser Prägung, das heißt mit nicht ganz kompensierter Spinndrehung, sind überwiegend gebräuchlich.The invention has for its object to provide a combined spinning-twisting method and a corresponding device with which it is possible to obtain any level of twist between the single strands or single threads on the one hand and the twist on the other hand in the finished twine . Threads of this type, that is, with a not completely compensated spinning twist, are predominantly used.

Zur Lösung dieser Aufgabe dient ein Verfahren mit den Merkmalen des Patentanspruchs 1 sowie eine Vorrichtung gemäß dem Anspruch 2.A method with the features of claim 1 and a device according to claim 2 serve to achieve this object.

Der Kerngedanke der vorliegenden Erfindung besteht im wesentlichen darin, an sich bekannte Ringspinneinrichtungen mit auch an sich bekannten Hohlspindeln auszurüsten und jeweils zwei dieser Ringspinneinrichtungen übereinander anzuordnen, so daß die auf diesen beiden Ringspinneinrichtungen nach dem Ringspinnverfahren hergestellten zwei Spinnfäden anschließend bei rotierenden Spindeln unter Ballonbildung durch die Hohlachsen derselben abgezogen und unterhalb der unteren Hohlspindel beispielsweise zu einer Zwirn-Kreuzspule aufgewickelt werden. Durch entsprechende Anpassung bzw. Abstimmung der Spindeldrehzahlen während des Spinnprozesses einerseits und unter Einbeziehung der Zwirnfaden-Aufwickelgeschwindigkeit während des anschließenden Zwirnprozesses andererseits lassen sich die unterschiedlichsten Drehverhältnisse zwischen den einzelnen Spinnfäden einerseits und der Zwirndrehung des fertigen Zwirns andererseits erreichen, zum Beispiel auch dadurch, daß die beiden übereinander angeordneten Spindeln mit unterschiedlichen Drehzahlen angetrieben werden.The main idea of the present invention consists essentially in ring spinning devices which are known per se and which are also known per se Equip hollow spindles and arrange two of these ring spinning devices one above the other, so that the two spinning threads produced on these two ring spinning devices by the ring spinning process are then drawn off with rotating spindles with balloon formation through the hollow axes of the same and wound below the lower hollow spindle, for example to form a twisted cheese package. By appropriate adaptation or coordination of the spindle speeds during the spinning process on the one hand and taking into account the thread winding speed during the subsequent threading process on the other hand, the most varied rotation ratios between the individual spun threads on the one hand and the thread twist of the finished thread on the other hand can be achieved, for example also by the fact that the two spindles arranged one above the other are driven at different speeds.

Die für den Aufbau der Spinnfaden-Garnkörper erforderlichen Einrichtungen, wie Spindelantriebselemente, Ringbank, Spinnring und Läufer sowie vorgeschaltete Streckwerke, entsprechen den üblichen Elementen einer Ringspinnmaschine, wobei die Ringbankbewegung wie üblich zentral gesteuert wird, um die erwünschten Garnkörper herzustellen.The equipment required for the construction of the spun yarn packages, such as spindle drive elements, ring bench, spinning ring and rotor and upstream drafting units, correspond to the usual elements of a ring spinning machine, the ring bench movement being controlled centrally, as usual, in order to produce the desired packages.

Für den anschließenden Zwirnprozeß werden die Ringbankbewegungen unterbrochen. Unterhalb jedes Hohlspindelpaares - bestehend aus jeweils zwei übereinander angeordneten Hohlspindeln - angeordnete Aufwickelaggregate, wie sie beispielsweise bei Doppeldraht-Zwirnspindeln bekannt sind, dienen dann zum Aufbau der Zwirn-Kreuzspulen oder dergleichen. Während des Zwirnprozesses werden die zuvor zu den Spinnfaden-Garnkörpern aufgewickelten Spinnfäden in dem zweiten Arbeitsschritt unter Ballonbildung wieder von den Garnträgern abgezogen und durch die Hohlachsen der beiden Hohlspindeln dem Aufwickelwerk zugeführt. Die Friktionswalze des Aufwickelwerkes arbeitet dabei in Abhängigkeit von der Spindeldrehzahl mit einer solchen Geschwindigkeit (Abzugsgeschwindigkeit), daß die Drehungen der einzelnen Spinnfäden entweder ganz oder teilweise zurückgedreht werden.The ring bench movements are interrupted for the subsequent twisting process. Beneath each pair of hollow spindles - each consisting of two hollow spindles arranged one above the other - arranged winding units, such as are known, for example, in the case of double-wire twisting spindles, are then used to construct the twisted cross-wound bobbins or the like. During the twisting process, the In the second step, the spun threads previously wound into the spun yarn packages are pulled off the yarn carriers with balloon formation and fed to the winding unit through the hollow axes of the two hollow spindles. The friction roller of the take-up unit works depending on the spindle speed at such a speed (take-off speed) that the rotations of the individual filaments are either wholly or partially turned back.

Die Erfindung wird im folgenden anhand der Zeichnungen näher beschrieben.The invention is described below with reference to the drawings.

Figur 1 zeigt in schematischer Darstellung zwei übereinander angeordnete Ringspinneinrichtungen mit Hohlspindeln sowie ein nachgeschaltetes Fadenaufwickelwerk während des einen ersten Arbeitsschritt darstellenden Spinnprozesses.Figure 1 shows a schematic representation of two stacked ring spinning devices with hollow spindles and a downstream thread winding unit during the spinning process representing a first step.

Figur 2 zeigt in schematisierter Darstellung die gleiche Einrichtung während des in einem zweiten Arbeitsschritt durchgeführten Zwirnprozesses.Figure 2 shows a schematic representation of the same device during the twisting process carried out in a second step.

Gemäß Figur 1 sind zwei nur ausschnittsweise dargestellte Ringspinnmaschinen 1 bzw. 1' übereinander angeordnet. Jede Ringspinnmaschine enthält eine Spindelbank 2 bzw. 2' zur Lagerung von Hohlspindeln 3 bzw. 3', von denen in der Zeichnung für jede Ringspinnmaschine nur jeweils eine Hohlspindel dargestellt ist. Die einzelne Hohlspindel 3 bzw. 3' umfaßt eine Spindelhohlachse 4 bzw. 4' mit Antriebswirtel 5 bzw. 5', um den ein Spindelantriebsriemen 6 bzw. 6' gelegt ist, der über Umlenk- und/oder Spannrollen 7 bzw. 7' und eine Antriebsscheibe 8 bzw. 8' geführt ist, die jeweils auf einer zentral angetriebenen Welle 9 bzw. 9' befestigt ist. In Richtung der Doppelpfeile f1 bzw. f1' auf- und abbewegbare, an einer nicht dargestellten Ringbank befestigte Ringhalter 10 bzw. 10' tragen Spinnringe 11 bzw. 11' für die bei Ringspinnmaschinen übliche Ringläufer 12 bzw. 12'.According to FIG. 1, two ring spinning machines 1 and 1 ', which are only shown in sections, are arranged one above the other. Each ring spinning machine contains a spindle bank 2 or 2 'for the storage of hollow spindles 3 or 3', of which only one hollow spindle is shown in the drawing for each ring spinning machine. The individual hollow spindle 3 or 3 'comprises a spindle hollow axis 4 or 4' with drive whorls 5 or 5 ', around which a spindle drive belt 6 or 6' is placed, which is connected to deflection and / or tensioning rollers 7 or 7 'and a drive pulley 8 or 8 'is guided, each on a centrally driven shaft 9 or 9 'is attached. Ring holders 10 and 10 ', which can be moved up and down in the direction of the double arrows f1 and f1' and are attached to a ring bench (not shown), carry spinning rings 11 and 11 'for the ring travelers 12 and 12' which are customary in ring spinning machines.

Jeder Hohlspindel 3 bzw. 3' ist ein in einem Spulengatter angebrachter Vorgarnkörper, beispielsweise Flyerspule 13 bzw. 13' oder Fournisseur-Spule zugeordnet, der einen Vorgarnvorrat darstellt. Das von diesen Flyerspulen 13 bzw. 13' kommende Vorgarn a bzw. a' wird bei laufender Hohlspindel 3 bzw. 3' abgezogen und mittels eines üblichen Streckwerkes 14 bzw. 14' verstreckt, bevor es nach Passieren eines in der Verlängerung der Spindelhohlachse liegenden Fadenführers 15 bzw. 15' bei sich auf- und abbewegendem Spinnring 11 bzw. 11' verdreht und zu einem Spinngarnkörper 16 bzw. 16' aufgewickelt wird.Each hollow spindle 3 or 3 'is assigned a roving body, for example a flyer spool 13 or 13' or a feeder bobbin, which represents a roving supply. The roving a or a 'coming from these flyer bobbins 13 or 13' is drawn off while the hollow spindle 3 or 3 'is running and stretched by means of a conventional drafting unit 14 or 14' before passing through a thread guide lying in the extension of the hollow spindle axis 15 or 15 'is rotated when the spinning ring 11 or 11' moves up and down and is wound up to form a spinning yarn body 16 or 16 '.

Unterhalb der unteren Hohlspindel 3' ist ein Aufwickelwerk 17 angeordnet, das einen Spulenhalterrahmen 18 zur Halterung einer Spulenhülse, eine mittels der Welle 19 antreibbare Antriebswalze 20 und einen Changierfadenführer 21 umfaßt, wie es beispielsweise bei Aufwickelwerken von Doppeldraht-Zwirnspindeln bekannt ist. Der Changierfadenführer 21 ist mittels der Changierstange 22 in Richtung des Doppelpfeiles f2 (siehe Figur 2) hin- und hergehend antreibbar.Below the lower hollow spindle 3 ', a winding mechanism 17 is arranged, which comprises a bobbin holder frame 18 for holding a bobbin tube, a drive roller 20 which can be driven by means of the shaft 19 and a traversing thread guide 21, as is known, for example, in the winding mechanisms of double-wire twisting spindles. The traversing thread guide 21 can be driven back and forth in the direction of the double arrow f2 (see FIG. 2) by means of the traversing rod 22.

Sobald mittels des einen ersten Arbeitsschritt darstellenden Spinnprozesses Spinngarnkörper 16 bzw. 16' aufgewickelt worden sind, wird der Spinnprozeß unterbrochen, wobei gemäß Figur 2 der Antrieb der Ringhalter 10 bzw. 10' stillgesetzt wird. Die zuvor zu den Spinngarnkörpern 16 bzw. 16' aufgewickelten Spinnfäden b bzw. b' werden dann in einem zweiten Arbeitsschritt von den Garnkörpern 16 bzw. 16' unter Ballonbildung abgezogen, wobei der von dem oberen Spinngarnkörper 16 abgezogene Spinnfaden b zuerst durch die Hohlspindel 3 und dann gemeinsam mit dem von dem unteren Spinngarnkörper 16' abgezogenen Spinnfaden b' durch die untere Hohlspindel 3' hindurchgeführt wird, bevor beide anschließend als Zwirnfaden c zu der von der Antriebswalze 20 angetriebenen Kreuzspule 24 aufgewickelt werden. Die Hohlspindeln 3 und 3' werden von dem auf die jeweiligen Spindelwirtel 5 bzw. 5' wirkenden Antriebsriemen 6 bzw. 6' in Abhängigkeit von der Abzugsgeschwindigkeit des Aufwickelwerkes 17 derart in Rotation versetzt, daß die den Spinnfäden b bzw. b' während des Spinnprozesses erteilten Drehungen entweder ganz oder teilweise zurückgedreht werden.As soon as spinning yarn bodies 16 or 16 'have been wound up by means of the spinning process which represents a first working step, the spinning process is interrupted, the drive of the ring holder 10 or 10' being stopped according to FIG becomes. The spun yarns b and b 'previously wound into the spun yarn bodies 16 and 16' are then drawn off from the yarn bodies 16 and 16 'with the formation of a balloon in a second step, the spun yarn b drawn off from the upper spun yarn body 16 first through the hollow spindle 3 and then, together with the spinning thread b 'drawn off from the lower spun yarn body 16', is passed through the lower hollow spindle 3 'before both are then wound up as twisted thread c to form the cross-wound bobbin 24 driven by the drive roller 20. The hollow spindles 3 and 3 'are rotated by the drive belt 6 or 6' acting on the respective spindle whorls 5 and 5 'depending on the take-off speed of the winding unit 17 in such a way that the spun threads b and b' during the spinning process granted rotations can be reversed either in whole or in part.

Wie oben erläutert, besteht die erfindungsgemäße Lösung darin, während der auf Ringspinneinrichtungen durchgeführten Spinnprozesse einen auf Hohlspindeln installierten, permanent angebrachten Garnträger zum Aufbau von Spinngarnkörpern 16 bzw. 16' zu verwenden, von denen während des anschließenden Zwirnprozesses die Spinnfadenkomponenten wieder abgezogen und durch die Hohlachsen der rotierend angetriebenen Hohlspindeln zu einem Aufwickelwerk geführt werden. Auf diese Weise entfällt der sonst übliche Transport eines auf einer Ringspinneinrichtung hergestellten Spinngarnkörpers zu einer gesonderten Zwirneinrichtung; es ist weiterhin nicht mehr erforderlich, nach Abnahme eines Spinngarnkörpers von der üblichen Spindel einer Ringspinneinrichtung diese Spindeln erneut mit leeren Spulenhülsen zu bestücken.As explained above, the solution according to the invention consists in using, during the spinning processes carried out on ring spinning devices, a permanently attached yarn carrier installed on hollow spindles for the construction of spun yarn bodies 16 or 16 ', from which the spinning yarn components are drawn off again during the subsequent twisting process and through the hollow axes the rotatingly driven hollow spindles are guided to a winding unit. In this way, the otherwise usual transport of a spun yarn body produced on a ring spinning device to a separate twisting device is eliminated; it is also no longer necessary, after removing a spun yarn body from the usual spindle of a ring spinning device, to close these spindles again with empty bobbin tubes equip.

Jeweils zwei nebeneinander angeordnete Hohlspindelpaare, bestehend aus jeweils zwei übereinander angeordneten Hohlspindeln, kann ein gemeinsames Aufwickelwerk zugeordnet sein, das dann im wesentlichen mittig unterhalb den beiden Hohlspindelpaaren angeordnet ist, wobei der fertige Zwirn wechselweise von jeweils zwei übereinander angeordneten Spindeln zuläuft. Damit ist praktisch ein Continu-Prozess auch für die Zwirnaufwindung geschaffen, der auch mit einfachen und aus der Technik bekannten Mitteln bezüglich der Fadeneinfädelung, Fadenführung und Zwirnverbindung, zum Beispiel durch Knoten oder Spleißen, dargestellt werden kann. Entsprechend ist dann den beiden nebeneinander liegenden Hohlspindeln jeweils ein Vorgarnkörper zugeordnet.In each case two pairs of hollow spindles arranged next to each other, each consisting of two hollow spindles arranged one above the other, can be assigned a common winding unit, which is then arranged essentially centrally below the two pairs of hollow spindle, the finished thread alternately running from two spindles arranged one above the other. This practically creates a continuation process for twisting the thread, which can also be represented with simple means known from the art regarding thread threading, thread guidance and thread connection, for example by knots or splicing. Correspondingly, a roving body is then assigned to each of the two hollow spindles lying next to one another.

Claims (4)

  1. Method of manufacturing a twisted thread in the case of which, in a first working step, two roved fibres (a; a'), drawn off from rove supplies and guided through drawing mechanisms, are in each case spun independently of one another according to the ring spinning method and in the process are wound onto yarn carriers, which are permanently mounted on hollow spindles (3; 3') arranged one above the other, to form two spun yarn packages (16; 16'), after which, in a subsequent second working step, with previous separation oF the ends of the spun threads (b; b') from the drawn roved fibres, the spun threads (b; b') previously wound to form spun yarn packages are each drawn off again with formation of a balloon from the spun yarn packages and are together fed through the hollow shafts (4; 4') of the respective hollow spindles with simultaneous guiding of the spun threads through the upper hollow spindle and through the lower hollow spindle to a winding mechanism (17) located underneath the lower hollow spindle, whereby the hollow spindles are set rotating, depending on the draw-off speed of the winding mechanism, in such a way that the twist of the two spun threads is at least partly twisted back again.
  2. Device for implementing the method according to Claim 1, including ring spinning devices respectively arranged one above the other with hollow spindles (3; 3'), which are carried on spindle bearing plates (2; 2') located one above the other and are provided with permanently installed yarn carriers, and with a winding mechanism (17) located underneath the two hollow spindles (3; 3'), whereby the respective hollow spindles (3; 3') are guided through the spindle bearing plates and in each case have awhorl (5; 5'), which can be driven by means of a driving belt (10; 10'), for the adjustment of rotational speeds which are in predeterminable relationship with one another, a ring (11; 11'), which can move up and down, with associated ring traveller (12; 12') being assigned to each hollow spindle, and a drawing mechanism (14; 14'), which is standard with ring spinning devices, being arranged ahead of each hollow spindle.
  3. Device according to Claim 2, characterized in that a shared winding mechanism (17) is associated respectively with two pairs of hollow spindles located side by side, each comprising two hollow spindles (3; 3') arranged one above the other, this winding mechanism (17) being located essentially in the middle underneath the two pairs of hollow spindles.
  4. Device according to Claims 2 and 3, characterized in that a shared drawing mechanism with the corresponding rove supply is associated with each pair of hollow spindles.
