Description

Die vorliegende Erfindung betrifft gemäss dem Oberbegriff denunabhängigen Anspruch 1, eine Textilmaschine mit mehreren Spinnstellen sowie verschiedene Vorrichtungen dazu.The present invention relates according to the preamble of the independent claim 1, a textile machine with several spinning stations and various devices thereto.

Derartige Vorrichtungen sind in der Textiltechnik hinreichend bekannt. Eine solche Vorrichtung ist beispielsweise der DE 42 12 701 C2 oder der DE 39 31463 A1 zu entnehmen. Diese Schrift offenbart eine Rotor-Spinnmaschine mit einer Vielzahl von nebeneinander angeordneten Spinnstellen, wobei jede Spinnstelle eine Kannenvorlage, eine Spinneinheit und eine Spulvorrichtung aufweist.Such devices are well known in the textile art. Such a device is for example the DE 42 12 701 C2 or the DE 39 31463 A1 refer to. This document discloses a rotor spinning machine with a plurality of juxtaposed spinning stations, each spinning station having a can template, a spinning unit and a winding device.

Nachteilig an einer Vorrichtung gemäss der soeben genannten Patentschriften ist, dass bei Ausfällen der Spinneinheit oder der Aufspuleinheit die gesamte Spinnstelle ausser Betrieb ist.A disadvantage of a device according to the aforementioned patents is that in case of failure of the spinning unit or Aufspuleinheit the entire spinning unit is out of operation.

Die Offenlegungsschrift DE 36 24 904 A1 offenbart eine gattungsfremde Textilmaschine, beziehungsweise eine Kreuzspulenwickelmaschine, welche nach einem Baukastenprinzip aus vormontierten Baueinheiten besteht. Diese Kreuzspulenwickelmaschine kann mit Hilfe von mehreren standardisierten und vormontierten Baueinheiten auf verschiedene Bauarten umgerüstet werden. Gemäss diesem Stand der Technik besitzt jede Baueinheit oder jede Baugruppe für das wechselseitige lagegenaue Verklammern vorbereitete Befestigungsmittel, Lagefixiermittel und/oder Kupplungen für Energieführungsmittel. Das Baukastenprinzip ist daher bei Kreuzspulenwickelmaschinen bekannt. Kreuzspulenwickelmaschinen führen einen Umspulvorgang durch, welcher wesentlich einfacher ist, als der Spinnprozess in einer Spinnstelle, denn die Wickelmaschine arbeitet im Gegensatz zu Spinnmaschinen mit einem zusammenhängenden, durchgehenden Garn. Bei den gattungsfremden Texturiermaschinen ist es beispielsweise nach DE 36 23 370 A1 und DE 197 05 810 A1 ebenfalls bekannt, mehrere Module für die Maschine vorzusehen. Im Gegensatz zu Spinnmaschinen arbeiten auch Texturiermaschinen mit durchgehenden und vor allem elastischen Filamenten. US3,990,219 A1 offenbart eine Textilmaschine gemäß dem Oberbegriff des Anspruchs 1.The publication DE 36 24 904 A1 discloses a non-generic textile machine, or a cheese winding machine, which consists of a modular principle of pre-assembled units. This cheese winding machine can be converted to various types with the help of several standardized and pre-assembled units. According to this prior art, each assembly or assembly for mutual registration clamping has prepared fasteners, position fixings and / or couplings for energy conducting means. The modular principle is therefore known in cheese winding machines. Cross-wound bobbin winding machines perform a rewinding process, which is much simpler than the spinning process in a spinning station, because the winding machine works in contrast to spinning machines with a continuous, continuous yarn. In the generic texturing, it is for example after DE 36 23 370 A1 and DE 197 05 810 A1 also known to provide several modules for the machine. In contrast to spinning machines also texturing machines work with continuous and above all elastic filaments. US3,990,219 A1 discloses a textile machine according to the preamble of claim 1.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die Spinnstellen derart zu gestalten, dass Stillstandzeiten aufgrund von Ausfällen von Maschinenbestandteilen der Spinnstelle oder bei Umrüstung der Spinnstelle minimiert werden.The present invention is therefore based on the object to design the spinning stations such that downtime due to failures of machine components of the spinning station or when refitting the spinning station are minimized.

Die ErfindungThe invention

Die Aufgabe der Erfindung wird durch die im unabhängigen Patentanspruch 1, angegebenen Merkmale gelöst.The object of the invention is achieved by the features specified in the independent claim 1.

Durch die Verwendung von modular aufgebauten und auswechselbaren Spinn- und Aufspuleinheiten ist es möglich, bei Ausfällen, bzw. Pannen, der genannten Vorrichtungen, diese einfach und schnell auszuwechseln. Durch die Auswechselbarkeit werden die Stillstandzeiten bei derartigen Ereignissen wesentlich reduziert. Die modular aufgebauten und auswechselbaren Spinn- und Aufspuleinheiten haben daneben noch einen weiteren Vorteil: Dank dem modularen Aufbau kann man auf derselben Textilmaschine Garn mit unterschiedlichen Spinnverfahren herstellen. Eine Spinnmaschine mit einem derartigen modularen Aufbau ist daher vielseitig einsetzbar. Auf derselben Maschine können Spinneinheiten gleichzeitig unterschiedliches Garn herstellen. Zum Beispiel Garn, welches mit einem Luftspinnverfahren hergestellt wird und Garn, welches mit einem Rotorspinnverfahren produziert wird. Dank dem modularen Aufbau und der Auswechselbarkeit kann man die Spinnstellen sehr schnell umrüsten und damit schneller und flexibler Garne nach Kundenwunsch herstellen. Eine solche Textilmaschine erlaubt daher nicht nur niedrigere Stillstandzeiten, sondern auch erhöhte Flexibilität und geringere Investitionskosten. Die Verwendung von auswechselbaren Aufspuleinheiten bringt überdies den Vorteil, dass unterschiedliche Wicklungsarten, beziehungsweise unterschiedliche Spulen, produziert werden können.By using modular and interchangeable spinning and Aufspuleinheiten it is possible in case of failure, or breakdowns, the said devices to replace them easily and quickly. The interchangeability of the downtimes are significantly reduced in such events. The modular and interchangeable spinning and winding units also have another advantage: thanks to the modular design, yarns with different spinning processes can be produced on the same textile machine. A spinning machine with such a modular structure is therefore versatile. On the same machine, spinning units can produce different yarns at the same time. For example, yarn produced by an air-spinning method and yarn produced by a rotor-spinning method. Thanks to the modular design and the interchangeability, the spinning stations can be retrofitted very quickly, thus producing yarns that are faster and more flexible according to customer requirements. Therefore, such a textile machine not only allows lower downtime, but also increased flexibility and lower investment costs. The use of interchangeable Aufspuleinheiten also brings the advantage that different types of winding, or different coils can be produced.

Vorteilhafte Ausgestaltungen und Ausführungsformen der Erfindung sind in den weiteren abhängigen Ansprüchen angegeben.Advantageous embodiments and embodiments of the invention are specified in the further dependent claims.

Im folgenden wird die Erfindung und der Erfindungsgedanke anhand eines in der Figur dargestellten Ausführungsbeispieles erläutert. Es soll aber ausdrücklich darauf hingewiesen werden, dass sich die Erfindung nicht auf dieses Beispiel beschränkt.In the following the invention and the inventive concept will be explained with reference to an embodiment shown in the figure. It is to be expressly understood, however, that the invention is not limited to this example.

Die Figur 1 zeigt schematisch (im Querschnitt) eine Spinnstelle einer Textilmaschine 1. Die Textilmaschine 1 ist doppelseitig, wobei die Figur nur eine Seite der Maschine zeigt (strichpunktierte Linie zeigt die Spiegelachse der Textilmaschine 1). Selbstverständlich wäre es auch denkbar, dass die in der Figur gezeigte Textilmaschine 1 nur einseitig gebaut ist. Die Spinnstellen der Textilmaschine 1 weisen eine Kannenvorlage 2 auf. Die Kannenvorlage 2 kann eine oder, wie in der Figur dargestellt, zwei Kannen 14 aufnehmen. Für die Erfindung ist es dabei irrelevant, ob eine oder mehrere Kannen 14 vorhanden sind und ob die Kannenvorlage 2 in, neben oder vor der Spinnstelle angeordnet ist. Es wäre auch denkbar, dass eine Kannenvorlage 2 mehrere Spinneinheiten 3, beziehungsweise mehrere Spinnstellen, mit Faserband beliefert. Dies bedeutet, dass die Erfindung auch die Möglichkeit umfasst, dass eine Kannenvorlage 2 mehrere Spinnstellen (zum Beispiel zwei) mit Fasermaterial versorgt.The FIG. 1 schematically shows (in cross section) a spinning station of a textile machine 1. The textile machine 1 is double-sided, the figure shows only one side of the machine (dash-dotted line shows the mirror axis of the textile machine 1). Of course, it would also be conceivable that the textile machine 1 shown in the figure is built only on one side. The spinning units of the textile machine 1 have a can presentation 2. The can template 2 can accommodate one or, as shown in the figure, two cans 14. For the invention, it is irrelevant whether one or more cans 14 are present and whether the can presentation 2 is arranged in, beside or in front of the spinning station. It would also be conceivable that a can template 2 supplies a plurality of spinning units 3, or several spinning stations, with sliver. This means that the invention also includes the possibility that a can original 2 supplies several spinning stations (for example two) with fiber material.

Charakteristisch für eine Spinnstelle ist jedoch, dass sie eine Spinneinheit 3 und eine Aufspuleinheit4 aufweist. Erfindungsgemäss sind die Spinneinheit 3 und die Aufspuleinheit 4 modular aufgebaut und auswechselbar (in der Figur schematisch dargestellt). Der Begriff "modular" im Sinne der Erfindung ist derart zu verstehen, dass diese Einheiten selbsttragende, aus Einzelheiten zusammengesetzte Baueinheiten bilden, welche auf, in oder an das Textilmaschinengestell 15 angehängt werden können. Mittels nicht dargestellten Steckverbindungen können die Spinneinheiten 3 und die Aufspuleinheiten 4 soweit notwendig mit Strom und Druckluft vom Maschinengestell 15 aus, sowie mit Steuersignalen von einer zentralen Maschinensteuerung 5, versorgt werden. Die Modulbauweise der Einheiten 3 und 4 erlaubt es auch, dass unterschiedliche Spinn- oder Aufspuleinheiten auf demselben Textilmaschinengestell 15 eingebaut werden können. Beispielsweise können unterschiedliche Spinneinheiten 3 vorgesehen sein, die in Bezug auf das verwendete Spinnverfahren, bzw. Garnbildungsverfahren, unterschiedliche Spinnboxen 11 aufweisen. Zum Beispiel können auf demselben Textilmaschinengestell 15 einzelne Spinneinheiten 3 Spinnboxen 11 aufweisen, welche Garn nach dem Luftspinnverfahren herstellen und andere Spinneinheiten 3 Spinnboxen 11 aufweisen, welche das Garn nach einem Rotorspinnverfahren herstellen. Das Textilmaschinengestell 15 muss dafür mit entsprechenden Anschlüssen für Strom und Druckluft sowie Abluft ausgestattet sein (nicht dargestellt). Nebst einer zentralen Maschinensteuerung 5 ist es von Vorteil, wenn die Spinneinheit 3 und die Aufspuleinheit 4 zusätzlich über eine auswechselbare Steuereinheit 6 verbunden sind. Die auswechselbare Steuereinheit 6 übernimmt die Steuerung der einzelnen Spinnstelle, insbesondere steuert und überwacht sie den Garnbildungsprozess an der Spinneinheit 3 und die Übergabe des produzierten Garns an die Aufspuleinheit 4. Die auswechselbare Steuereinheit 6 ist insbesondere in der Lage, die unterschiedlichen Liefergeschwindigkeiten von den verschiedenen Spinneinheiten 3 für die Aufspuleinheit 4 zu berücksichtigen. Das heisst, sie ist insbesondere in der Lage, die Liefergeschwindigkeiten, beziehungsweise Produktionsgeschwindigkeiten, der Spinneinheiten 3 und Aufspuleinheiten 4 zu steuern. Selbstverständlich kann die zentrale Maschinensteuerung 5 ebenfalls mit den auswechselbaren Steuereinheiten 6 der einzelnen Spinnstellen verbunden sein. Es können somit Steuerbefehle, zum Beispiel durch das Bedienungspersonal, von der zentralen Maschinensteuerung 5 über die auswechselbaren Steuereinheiten 6 der einzelnen Spinnstellen an die einzelnen Maschineneinheiten (Spinn- oder Aufspuleinheiten) abgegeben werden. Derartige Steuersignale, welche über die zentrale Steuerung 5 abgegeben werden, sind zum Beispiel das Anund Abstellen der gesamten Spinnmaschine oder der Verzug in den Verfeinerungseinheiten (Streckwerke) der Spinneinheiten.Characteristic of a spinning station, however, is that it has a spinning unit 3 and a winding unit 4. According to the invention, the spinning unit 3 and the winding unit 4 are of modular design and can be exchanged (shown schematically in the figure). The term "modular" within the meaning of the invention is to be understood such that these units form self-supporting, composed of details units that can be attached to, in or on the textile machine frame 15. By means not shown Plug connections, the spinning units 3 and the winding units 4 as necessary with power and compressed air from the machine frame 15, as well as with control signals from a central machine control 5, are supplied. The modular construction of units 3 and 4 also allows different spinning or winding units to be installed on the same textile machine frame 15. For example, different spinning units 3 can be provided, which have different spin boxes 11 with respect to the spinning method or yarn formation method used. For example, on the same textile machine frame 15, individual spinning units 3 may comprise spin boxes 11 which produce yarn by the air spinning method and other spinning units 3 have spin boxes 11 which produce the yarn by a rotor spinning method. The textile machine frame 15 must be equipped with appropriate connections for electricity and compressed air and exhaust air (not shown). In addition to a central machine controller 5, it is advantageous if the spinning unit 3 and the winding unit 4 are additionally connected via an interchangeable control unit 6. The interchangeable control unit 6 takes over the control of the individual spinning station, in particular it controls and monitors the yarn formation process on the spinning unit 3 and the transfer of the produced yarn to the winding unit 4. The interchangeable control unit 6 is in particular capable of the different delivery speeds of the various spinning units 3 for the winding unit 4 to be considered. This means that it is in particular able to control the delivery speeds or production speeds of the spinning units 3 and winding units 4. Of course, the central machine controller 5 may also be connected to the interchangeable control units 6 of the individual spinning stations. It can thus control commands, for example, by the operator, from the central machine controller 5 via the interchangeable control units 6 of the individual spinning units to the individual machine units (spinning or Aufspuleinheiten) are submitted. Such control signals, which are output via the central controller 5, are, for example, starting and stopping the entire spinning machine or the delay in the refinement units (drafting units) of the spinning units.

Im weiteren ist es ebenfalls vorgesehen, dass die Spinneinheit 3 oder auch die Aufspuleinheit4 eigene Steuerungen 7 und 8 aufweisen. Diese dienen der Umsetzung der erhaltenen Steuerbefehle auf die konkret vorhandenen Maschineneinheiten (zum Beispiel bei der Spinneinheit 3 die Steuerung der Motoren 12 oder der Spinnbox 11). Die Steuerung der Spinneinheit 8 hat insbesondere ein kontrolliertes Ein- und Abschatten der gesamten Spinneinheit 3 zu steuern. Dafür kann ein bestimmtes Verfahren vorgesehen sein.Furthermore, it is also provided that the spinning unit 3 or the Aufspuleinheit4 own controls 7 and 8 have. These are used to implement the control commands received on the actually existing machine units (for example, in the spinning unit 3, the control of the motors 12 or the spin box 11). The control of the spinning unit 8 in particular has to control a controlled insertion and removal of the entire spinning unit 3. For this, a specific method can be provided.

In einer bevorzugten Ausführungsform der Erfindung, weist die Textilmaschine an jeder Spinnstelle oder für jede Spinnstelle jeweils einen ebenfalls modular, im Sinne der vorhergehenden Ausführungen, aufgebauten und auswechselbaren Roboter 9 auf. Der Roboter 9 dient dazu, bei Maschinenstillstand mittels eines Hilfsgarns ein Anspinnen zu bewerkstelligen oder bei Fadenbruch das Ansetzen des Garnendes von der Spule mit dem neuen Garn zu bewerkstelligen. Es ist auch denkbar, dass der Roboter 9 mehrere Spinnstellen bedient (mit Hilfe einer nicht dargestellten Bewegungsvorrichtung).In a preferred embodiment of the invention, the textile machine at each spinning station or for each spinning station in each case a likewise modular, in the sense of the preceding embodiments, constructed and interchangeable robot 9. The robot 9 is used to accomplish a piecing in machine downtime by means of an auxiliary yarn or to accomplish threading the attachment of the yarn end of the spool with the new yarn. It is also conceivable that the robot 9 operates a plurality of spinning stations (with the aid of a movement device, not shown).

Bevorzugt weisen die Spinneinheiten 3 ebenfalls eine Verfeinerungseinheit 10 auf. Die in der Figur dargestellte Verfeinerungseinheit 10 stellt ein Streckwerk dar. Es wäre aber auch denkbar, dass anstelle des Streckwerks 10 eine Auflösewalze vorhanden ist. Ob eine Verfeinerungseinheit verwendet wird und welcher Typ, hängt insbesondere vom anschliessend in der Spinnbox 11 durchgeführten Spinnverfahren ab. Ist das Garnbildungsverfahren ein Rotorspinnverfahren, so wird bevorzugt eine Auflösewalze als Verfeinerungseinheit verwendet. Der eigentliche Garnbildungsprozess in der Spinneinheit3 wird in der Spinnbox 11 durchgeführt. Bevorzugt weist die modular aufgebaute und auswechselbare Spinneinheit 3 eine Spinnbox auf, welche ein Garn nach dem Luftspinnverfahren herstellt. Die Erfindung sieht aber auch vor, dass verschiedene Spinneinheiten 3 mit unterschiedlichen Spinnboxen 11 eingesetztwerden können. So können die Spinnboxen 11 beispielsweise Garn nach einem Rotorspinnverfahren, einem Friktionsspinnverfahren oder auch einem Falschdrallverfahren herstellen.The spinning units 3 preferably also have a refinement unit 10. The refinement unit 10 shown in the figure represents a drafting system. However, it would also be conceivable that instead of the drafting system 10, an opening roller is present. Whether a refinement unit is used and which type depends in particular on the spinning process subsequently carried out in the spin box 11. If the yarn-forming process is a rotor-spinning process, it is preferable to use an opening roller as the refinement unit. The actual yarn formation process in the spinning unit 3 is performed in the spin box 11. The modularly constructed and exchangeable spinning unit 3 preferably has a spinning box which produces a yarn by the air-spinning method. However, the invention also provides that different spinning units 3 can be used with different spin boxes 11. For example, the spin boxes 11 can produce yarn by a rotor spinning method, a friction spinning method or a false twist method.

Die Spinneinheit 3 kann auch Garnwächter 16 und Fadenwächter 17 aufweisen.The spinning unit 3 may also have yarn monitor 16 and thread monitor 17.

Wie in der Figur dargestellt, weisen die Spinneinheit 3 und die Aufspuleinheit 4 bevorzugt auch eigene Antriebe 12, beziehungsweise 13, auf. Die Spinneinheiten, beziehungsweise die Aufspuleinheiten, sind damit antriebstechnisch unabhängig. Sie beziehen lediglich Strom und Steuersignale - allenfalls noch Druckluft - über nicht dargestellte Steckverbindungen und Leitungen vom Textilmaschinengestell 15, beziehungsweise von der zentralen Maschinensteuerung 5 und/oder von der Steuereinheit der Spinnstelle 6. Die auswechselbaren Einheiten 3 und 4 weisen somit für die wesentlichen Verfahrensstufen eigene Antriebe auf und sind nicht über mechanische Kupplungen an einem zentralen Antrieb, welcher sich auf dem Textilmaschinengestell 15 befinden würde, angehängt. Zu den wesentlichen Verfahrensstufen, welche eigene Antriebe aufweisen, gehört bei der Aufspuleinheit 4 die Aufspulung, die einen Antrieb 13 für die Friktionswalze 18 aufweist. Zu den wesentlichen Verfahrensstufen bei der Spinneinheit 3 gehört die Verfeinerung in der Verfeinerungseinheit (im Ausführungsbeispiel gemäss Figur ein Streckwerk) und der Auslauf aus der Spinnbox. Die Spinneinheit 3 weist daher zwei eigene Antriebe 12 für die Walzen des Streckwerks und des Auslaufwalzenpaares auf. Bevorzugt sind die Antriebe Reluktanzmotoren; es können aber auch weitere Asynchronmotoren verwendet werden. Es ist durchaus denkbar, dass für weniger wichtige Prozessschritte mehrere Einheiten gemeinsame Antriebe aufweisen. Zum Beispiel können mehrere Aufspuleinheiten 4 gemeinsame Antriebe für die Changiervorrichtung 19 aufweisen (mechanische Kraftübertragung mittels einer Welle). Zu den wichtigen Prozessschritten, welche eigene Antriebe oder Motoren aufweisen, gehören wie erwähnt die Verfeinerung in der Verfeinerungseinheit 10 (Antriebe 12) sowie im Auslauf der Spinneinheit 3 oder der Antrieb 13 der Friktionswalze 18 in der Aufspuleinheit 4. Je nach verwendeter Spinnbox 11, kann die Spinneinheit 3 noch einen weiteren Antrieb (nicht gezeigt) für die Spinnbox 11 besitzen (zum Beispiel für das Rotorspinnverfahren). Die Verwendung eigener Antriebe für jede Einheit - insbesondere für die wesentlichen Verfahrensstufen - hat einige Vorteile. Beispielsweise sind keine mechanische Kupplungen, Kraftübertragungen, oder Getriebeübersetzungen notwendig. Damit sind die einzelnen Spinnstellen flexibler bzw. individuell einstellbar. Die Drehzahlverhältnisse können elektrisch z.B. leichter angepasst werden (z.B. der Verzug in der Verfeinerungseinheit oder die Auslaufgeschwindigkeit des Garnes aus der Spinnbox). Eine Synchronisation der Antriebe in der Spinnstelle kann - sollte sie notwendig sein - mit Hilfe der Steuerungen 5 und/ oder 6 bewerkstelligt werden. Mit Hilfe der eigenen Antriebe ist es antriebstechnisch auch einfacher, unterschiedliche Spinnstellen bzw. Spinneinheiten auf demselben Textilmaschinengestell gleichzeitig zu betreiben.As shown in the figure, the spinning unit 3 and the winding unit 4 preferably also have their own drives 12, 13, respectively. The spinning units, or the Aufspuleinheiten are thus independent in terms of drive technology. They only draw power and control signals - possibly compressed air - not shown connectors and lines from the textile machine frame 15, or from the central machine control 5 and / or from the control unit of the spinning unit 6. The interchangeable units 3 and 4 thus have for the essential process stages own Drives on and are not on mechanical clutches on a central drive, which would be located on the textile machine frame 15 attached. In the case of the winding-up unit 4, the winding, which has a drive 13 for the friction roller 18, belongs to the essential process stages, which have their own drives. Among the main stages of the spinning unit 3 is the refinement in the refinement unit (in the embodiment according to the figure, a drafting system) and the outlet from the spin box. The spinning unit 3 therefore has two separate drives 12 for the rolls of Drafting and the outlet roller pair on. Preferably, the drives are reluctance motors; but it can also be used asynchronous motors. It is quite conceivable that for less important process steps several units have common drives. For example, a plurality of winding units 4 may have common drives for the traversing device 19 (mechanical transmission by means of a shaft). As mentioned, the refinement in the refinement unit 10 (drives 12) and in the outlet of the spinning unit 3 or the drive 13 of the friction roller 18 in the winding unit 4 belong to the important process steps which have their own drives or motors the spinning unit 3 still another drive (not shown) for the spinning box 11 have (for example, for the rotor spinning method). The use of own drives for each unit - especially for the essential process stages - has some advantages. For example, no mechanical clutches, transmissions, or gear ratios are necessary. Thus, the individual spinning stations are more flexible or individually adjustable. The speed ratios can be adjusted electrically eg easier (eg the delay in the refinement unit or the outlet speed of the yarn from the spin box). A synchronization of the drives in the spinning station can - if they are necessary - be accomplished with the help of the controls 5 and / or 6. With the help of their own drives, it is also easier to drive different spinning stations or spinning units on the same textile machine frame simultaneously.

Die Erfindung eignet sich besonders für Spinneinheiten, die mit einem Luftspinnverfahren Garn herstellen. Bei diesem geschieht die Gambildung durch Luft-Drallerteilung. Die Spinnbox weist dafür jeweils einen Faserförderkanal mit einer Faserführungsfläche für das Führen des Stapelfaserverbandes auf, an dessen Ausgang eine Wirbelkammer vorhanden ist, welche ihrerseits eine Spindel mit einem Gamführungskanal umfasst. Die Wirbelkammer enthält eine Fluideinrichtung, welche eine Wirbelströmung (Luft) um die Einlassmündung des Garnführungskanals der Spindel erzeugt. Der Faserverband, beziehungsweise das Garn wird durch den Garnführungskanal abgezogen. Der Wirbelströmung um die Einlassmündung des Garnführungskanals verursacht beim Abziehen des Faserlängsgebildes ein Verdrehen der äusseren Fasern des Stapelfaserverbandes um dessen inneren Kern. Auf diese Weise wird aus einem Stapelfaserverband ein Garn hergestellt. Ein solches Verfahren offenbart beispielsweise die Schrift EP 854 214 (äquivalent zu US 5,927,0260 ).The invention is particularly suitable for spinning units which produce yarn by an air-spinning process. In this, the Gambildung done by air-twist distribution. The spinning box has for this purpose in each case a fiber conveying channel with a fiber guide surface for guiding the staple fiber strand, at whose output a vortex chamber is present, which in turn comprises a spindle with a Gamführungskanal. The swirl chamber includes a fluid device which generates a swirling flow (air) around the inlet mouth of the yarn guide channel of the spindle. The fiber structure, or the yarn is withdrawn through the Garnführungskanal. The turbulence around the inlet mouth of the Garnführungskanals causes when pulling the Faserlängsgebildes a twisting of the outer fibers of the staple fiber strand around the inner core. In this way, a yarn is made from a staple fiber strand. Such a method discloses, for example, the font EP 854 214 (equivalent to US 5,927,0260 ).
