Description

Die Erfindung betrifft eine Schmelzspinnvorrichtung zur Herstellung mehrerer Multifilamentfäden gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a melt spinning apparatus for producing a plurality of multifilament yarns according to the preamble of claim 1.

Eine gattungsgemäße Schmelzspinnvorrichtung ist aus der WO 2004/074155 bekannt.A generic melt spinning apparatus is known from WO 2004/074155 known.

Zur Herstellung von synthetischen Fäden werden derartige Schmelzspinnvorrichtungen in einer Mehrzahl zu einer kompletten Spinnanlage in einer Maschinenhalle kombiniert. Hierbei wird eine hohe Raumausnutzung gewünscht. Je größer die Anzahl der installierten Schmelzspinnvorrichtungen, umso höher wird die Produktionsleistung der Spinnanlage. Neben der Maschinenteilung der Schmelzspinnvorrichtungen wird die Produktivität im wesentlichen Maße durch die Anzahl der Fäden bestimmt, die pro Schmelzspinnvorrichtung herstellbar sind. Insoweit besteht der Wunsch, Schmelzspinnvorrichtungen möglichst kompakt mit möglichst großer Anzahl von Fäden auszubilden.For the production of synthetic threads, such melt spinning devices are combined in a plurality to a complete spinning plant in a machine shop. Here, a high space utilization is desired. The greater the number of installed melt spinning devices, the higher the production output of the spinning plant. In addition to the machine division of the melt spinning devices, the productivity is essentially determined by the number of threads that can be produced per melt spinning device. In that regard, there is a desire to form melt spinning devices as compact as possible with the largest possible number of threads.

Bei der gattungsgemäßen Schmelzspinnvorrichtung sind eine Spinneinrichtung, eine Abkühleinrichtung, eine Verstreckeinrichtung und eine Aufwickeleinrichtung zu einem vertikalen Fadenlauf untereinander angeordnet. Da die Spinneinrichtung mit den Spinndüsen, die Behandlungseinrichtung mit den Galetteneinheiten und die Aufwickeleinrichtung mit den Wickelstellen jeweils unterschiedliche Abstände zwischen den parallel geführten Fäden erfordern, sind Aufspreizungen oder Zusammenführungen der Fäden unumgänglich. Innerhalb der Fadenschar wird jedoch angestrebt, dass jeder der in der Schmelzspinnvorrichtung hergestellte Multifilamentfaden im Wesentlichen identische Eigenschaften aufweist. Daher sind Umlenkungen und Aufspreizungen, die zu unterschiedlichen Fadenspannungen in den Multifilamentfäden führen, möglichst zu vermeiden. Bei der gattungsgemäßen Schmelzspinnvorrichtung werden daher bei der Überführung der Fäden von der Behandlungseinrichtung zu den Wickelstellen der Aufwickeleinrichtung eine Umlenkeinrichtung sowie eine vertikal ausgerichtete Führungswalze genutzt, um durch mehrere Umlenkungen eine möglichst kompakte Fadenführung zu erhalten. Derartige Fadenführungen führen jedoch auch zum Aufbau unerwünschter Fadenspannungen. Insbesondere die Umlenkung an stationären Umlenkmittel verursachen erhöhte Fadenreibungen.In the generic melt spinning device, a spinning device, a cooling device, a drawing device and a winding device are arranged to one another to a vertical yarn path. Since the spinning device with the spinnerets, the treatment device with the godet units and the winding device with the winding stations each require different distances between the parallel guided yarns, spreading or merging of the threads are unavoidable. However, within the yarn sheet, it is desired that each of the multifilament yarns produced in the melt spinning apparatus have substantially identical properties. Therefore, deflections and spreads that are too different Thread tensions in the multifilament threads lead to avoid as possible. In the generic melt spinning device, a deflection device and a vertically oriented guide roller are therefore used in the transfer of the threads from the treatment device to the winding points of the winding device in order to obtain as compact as possible thread guide by a plurality of deflections. However, such thread guides also lead to the construction of unwanted thread tensions. In particular, the deflection of stationary deflection cause increased yarn friction.

Aus der WO 2004/015173 A1 ist eine weitere Schmelzspinnvorrichtung bekannt, bei welcher die Galetten der Behandlungseinrichtung zum Abziehen und Verstrecken der Fäden quer zu einer Spulspindel der Aufwickeleinrichtung ausgerichtet sind, um die Aufwickeleinrichtung und die Beharidlungseinrichtung möglichst kompakt auszubilden. Hierbei werden aber bevorzugt einfach umschlungene Galetten in der Verstreckeinrichtung verwendet, um innerhalb einer durch die Aufwickeleinrichtung definierte Maschinenteilung zu bleiben. Bei lang auskragenden Galetten, an denen die Fadenschar mit mehreren Umschlingungen geführt ist, lassen sich die Galetten daher kaum zu einer Baueinheit mit der Aufwickeleinrichtung kombinieren. Zur Herstellung von vollverstreckten Fäden mit größeren Fadentitern sind jedoch mehrfach umschlungene Galetten zur Fadenführung und Aufbau der Verstreckkräfte unerlässlich:From the WO 2004/015173 A1 another melt spinning apparatus is known in which the godets of the treatment device for drawing and drawing the threads are aligned transversely to a winding spindle of the take-up device in order to form the take-up device and the Beharidlungseinrichtung as compact as possible. In this case, however, preferably simply looped godets are used in the drawing device in order to remain within a machine pitch defined by the winding device. For long-projecting godets, in which the yarn sheet is guided with multiple wraps, the godets can therefore hardly combine to form a unit with the take-up device. For the production of fully drawn threads with larger thread tents, however, multiply looped godets for thread guidance and construction of the drawing forces are indispensable:

Es ist nun Aufgabe der Erfindung, die gattungsgemäße Schmelzspinnvorrichtung der eingangs genannten Art derart weiterzubilden, dass die an mehrfach umschlungenen Galetteneinheiten verstreckten Fäden möglichst fadenschonend ohne Aufspreizungen den Wickelstellen zuführbar sind.It is an object of the invention to develop the generic melt spinning device of the type mentioned in such a way that the yarns stretched on multiply looped godet units are fed to the winding points as possible without damaging the yarns without spreading.

Ein weiteres Ziel der Erfindung liegt darin, eine Schmelzspinnvorrichtung der gattungsgemäßen Art bereitzustellen, mit welchem vollverstreckte Fäden (FDY) in möglichst großer Anzahl parallel nebeneinander herstellbar sind.Another object of the invention is to provide a melt spinning apparatus of the generic type with which fully stretched Threads (FDY) in as large a number as possible parallel to each other.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Führungsgalette unterhalb der Verstreckeinrichtung derart axial quer zu den Galetten der Galetteneinheit ausgerichtet ist, dass beim Übergang die Fäden nach einer Drehung der Fadenlaufebene der Fadenschar um 90° mit einfacher Teilumschlingung an der Führungsgalette führbar sind.This object is achieved in that the Führungsgalette is aligned axially below the drawing device so axially transversely to the godets of the godet unit, that at the transition, the threads are feasible for rotation of the thread running plane of the yarn sheet by 90 ° with simple Teilumschlingung on the guide godet.

Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der Unteransprüche definiert.Advantageous developments of the invention are defined by the features and feature combinations of the subclaims.

Die Erfindung zeichnet sich dadurch aus, dass die die Tiefe der Schmelzspinnvorrichtung wesentlich beeinflussenden Bauteile gleichgerichtet sind, so dass eine im Wesentlichen durch die Aufwickeleinrichtung vorgegebene Maschinentiefe genutzt wird, um die Galetteneinheiten der Verstreckeinrichtung zu platzieren. Durch eine Drehung der Fadenlaufebene der Fadenschar lässt sich die Fadenschar ohne Umlenkung und Aufspreizung unmittelbar der Führungsgalette zuführen, die quer zu den Galetten der Galetteneinheit die Verstreckeinrichtung ausgerichtet ist. Die Drehung der Fadenschar erfolgt aus der durch die Verstreckeinrichtung bestimmten Fadenlaufebene um einen Winkel im Bereich von 90° in eine durch die Führungsgalette definierte neue Fadenlaufebene. Als Fadenlaufebene wird hier die durch die parallel nebeneinander geführten Fäden aufgespannte Ebene verstanden. Damit wird eine Aufspreizung der Fadenschar zur Verteilung der Fäden auf die Wickelstellen minimiert. Die erforderliche Umlenkung lässt sich allein durch rotierende Umlenkmittel wie die Führungsgalette ausführen.The invention is characterized in that the components substantially influencing the depth of the melt spinning device are rectified, so that a machine depth predetermined essentially by the winding device is used in order to place the godet units of the drawing device. By a rotation of the thread running plane of the yarn sheet, the group of threads without deflection and spreading can be fed directly to the guide godet, which is aligned transversely to the godets of the godet unit, the drawing device. The yarn bundle is rotated from the thread running plane determined by the stretching device by an angle in the region of 90 ° into a new thread running plane defined by the guide godet. As a thread running plane is here understood by the parallel juxtaposed threads spanned plane. This minimizes the spreading of the group of threads for the distribution of the threads on the winding points. The required deflection can be performed solely by rotating deflection such as the guide godet.

Bei einer ersten Weiterbildung der Erfindung lässt sich die Zuführung der verstreckten Fäden zu den Wickelstellen der Aufspulmaschine mit einer einfachen Teilumschlingung der Fadenschar an der Führungsgalette ausführen. Hierzu ist die Führungsgalette oberhalb der Spulspindel seitlich neben den Wickelstellen angeordnet, so dass nach Ablauf der Fäden von der Führungsgalette diese auf den einzelnen Wickelstellen verteilt werden können.In a first development of the invention, the feeding of the drawn threads to the winding stations of the winding machine can be carried out with a simple partial looping of the group of threads on the guide godet. For this purpose, the guide godet above the winding spindle is arranged laterally next to the winding points, so that after the threads of the Führungsgalette this can be distributed to the individual winding points.

Alternativ besteht jedoch auch die Möglichkeit, der Führungsgalette oberhalb der Spulspindel eine zweite gleichgerichtete Führungsgalette zuzuordnen, die seitlich neben den Wickelstellen angeordnet ist. Damit können insbesondere durch Antrieb der Führungsgaletten eine Wickelspannung zum Aufwickeln der Fäden in den Wickelstellen beeinflusst werden.Alternatively, however, it is also possible to assign the guide godet above the winding spindle a second rectified guide godet, which is arranged laterally next to the winding points. This can be influenced in particular by driving the Führungsgaletten a winding tension for winding the threads in the winding stations.

Darüber hinaus besteht die Möglichkeit, die zwischen den Führungsgaletten gebildete Führungsstrecke zur Weiterbehandlung der Fäden zu nutzen. So ist gemäß einer Weiterbildung der Erfindung vorgesehen, dass eine Verwirbelungseinrichtung zwischen den beiden Führungsgaletten angeordnet ist.In addition, it is possible to use the guide track formed between the guide godets for further treatment of the threads. Thus, according to a development of the invention, provision is made for a swirling device to be arranged between the two guide godets.

Um eine Vielzahl von Fäden gleichzeitig herstellen zu können, hat sich die Weiterbildung der Erfindung bewährt, bei welcher die Aufwickeleinrichtung durch zwei nebeneinander angeordnete Aufspulvorrichtungen gebildet wird, die jeweils mehrere Wickelstellen aufweisen. Die Führungsgalette ist hierzu bevorzugt in der Mitte oberhalb der Aufspulvorrichtungen gehalten. Damit lässt sich insbesondere die Tiefe der Aufwickeleinrichtung bei großer Anzahl von Fäden relativ klein halten. Zur verbesserten Fadenführung sind die Aufspulvorrichtungen bevorzugt spiegelsymmetrisch zueinander ausgeführt, so dass die Verteilung der Fadenschar nach Ablauf von der Führungsgalette aus einer Symmetrieebene heraus erfolgen kann.In order to be able to produce a multiplicity of threads at the same time, the development of the invention has proved successful, in which the winding device is formed by two winding devices arranged side by side, each of which has a plurality of winding points. The guide godet is this held preferably in the middle above the winding devices. In particular, the depth of the take-up device can thus be kept relatively small for a large number of threads. For improved thread guidance, the winding devices are preferably mirror-symmetrical to each other, so that the distribution of the group of threads can take place after expiration of the Führungsgalette from a plane of symmetry out.

Die Verteilung und Zuführung der Fäden zu den Wickelstellen erfolgt vorzugsweise gemäß der Weiterbildung der Erfindung, bei welcher zwischen der Führungsgalette und den Wickelstellen mehrere Umlenkrollen vorgesehen sind, die in den Wickelstellen jeweils einer Changiereinrichtung unmittelbar vorgeordnet sind. Damit lassen sich die Fäden mit geringer Fadenreibung den Wickelstellen zuführen.The distribution and feeding of the threads to the winding points is preferably carried out according to the embodiment of the invention, in which between the guide godet and the winding points a plurality of pulleys are provided, which are each arranged directly upstream of the winding points of a traversing device. This allows the threads with low yarn friction feed the winding points.

Zur Fadenstabilität bei der Führung der Fäden als eine Fadenschar lässt sich die erfindungsgemäße Schmelzspinnvorrichtung noch dadurch verbessern, dass zwischen der Führungsgalette und der letzten Galette der Verstreckeinrichtung ein Führungsmittel vorgesehen ist, durch welche die Änderung der Fadenlaufebene der Fadenschar um einen Winkel im Bereich von 90° bewirkt wird. Damit läßt sich der Ablauf der Fadenschar von der letzten Galette der Verstreckeinrichtung und der Zulauf der Fäden der Fadenschar zu der Führungsgalette wesentlich stabilisieren.For thread stability when guiding the threads as a group of threads, the melt spinning device according to the invention can be further improved by providing a guide means between the guide godet and the last godet of the stretching device, by which the change of the thread running plane of the yarn sheet by an angle in the range of 90 ° is effected. Thus, the course of the group of threads from the last galette of the drawing device and the feed of the threads of the group of threads to the Führungsgalette can be significantly stabilized.

Um innerhalb der durch die Spinndüsen verursachten Maschinenteilung eine möglichst hohe Anzahl von Fäden erhalten zu können, ist die Weiterbildung der Erfindung besonders bevorzugt ausgeführt, bei welcher die Spinndüsen jeweils als eine Doppeldüse ausgeführt sind, durch welche zwei Multifilamentfäden pro Spinndüse extrudierbar sind. Damit lässt sich eine hohe Anzahl von Fäden innerhalb der Spinneinrichtung bei sehr kompakter Anordnung der Spinndüsen parallel erzeugen. So besteht die Möglichkeit, dass die Reihe der Spinndüsen quer zu den Achsen der Galetteneinheiten der Verstreckeinrichtung ausgerichtet sind und gemeinsam mit den freien Enden der Galetteneinheiten und dem freien Ende der Spulspindel der Aufwickeleinrichtung eine Maschinenbedienungsseite zu bilden. Zur Stabilisierung der Fadenläufe ist ein Führungsmittel zwischen den Spinndüsen und der Verstreckeinrichtung vorgesehen, durch welches eine Änderung der Fadenlaufebene um einen Winkel im Bereich von 90° bewirkt wird.In order to obtain the highest possible number of threads within the machine pitch caused by the spinnerets, the development of the invention is particularly preferably carried out, in which the spinnerets are each designed as a double nozzle, through which two multifilament threads per spinneret are extrudable. This allows a large number of threads to be produced in parallel within the spinning device with a very compact arrangement of the spinnerets. Thus, there is the possibility that the row of spinnerets are aligned transversely to the axes of the godet units of the drafting device and to form, together with the free ends of the godet units and the free end of the winding spindle of the take-up device, a machine operating side. In order to stabilize the yarn paths, a guide means is provided between the spinnerets and the drafting device, by means of which a change in the thread running plane is effected by an angle in the region of 90 °.

Um trotz der kompakten Ausbildung der Spinneinrichtung jeden der einzeln extrudierten Multifilamentfäden gleichmäßig abkühlen zu können, ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher die Abkühleinrichtung zur Abkühlung der Fäden mehrere Kühlzylinder mit jeweils einer gasdurchlässigen Zylinderwand aufweist, die innerhalb einer Blaskammer angeordnet sind. Damit lässt sich jeder der Fäden der Fadenschar unter wesentlichen gleichen Bedingungen abkühlen.In order to be able to cool each of the individually extruded multifilament yarns evenly despite the compact design of the spinning device, the development of the invention is particularly advantageous in which the cooling device for cooling the threads has a plurality of cooling cylinders, each with a gas-permeable cylinder wall, which are arranged within a blow chamber. Thus, each of the threads of the yarn sheet can be cooled under substantially the same conditions.

Bei der Ausbildung der Spinndüsen als Doppeldüse ist die Weiterbildung der Erfindung bevorzugt eingesetzt, bei welcher jeder der Spinndüsen einer der Kühlzylinder zugeordnet ist, wobei die Kühlzylinder in zwei separate Kühlzonen geteilt sind. Somit können pro Spinndüse und Kühlzylinder mehrere Fäden gleichzeitig extrudiert und abgekühlt werden.In the formation of the spinnerets as a double nozzle, the development of the invention is preferably used, in which each of the spinnerets is associated with one of the cooling cylinders, wherein the cooling cylinders are divided into two separate cooling zones. Thus, several threads can be extruded and cooled simultaneously per spinneret and cooling cylinder.

Die erfindungsgemäße Schmelzspinnvorrichtung ist besonders geeignet, um vollverstreckte Fäden (FDY) herzustellen.The melt spinning device according to the invention is particularly suitable for producing fully drawn threads (FDY).

Die Erfindung wird nachfolgend anhand einiger Ausführungsbeispiele der Schmelzspinnvorrichtung näher beschrieben.The invention will be described in more detail below with reference to some embodiments of the melt spinning apparatus.

In den Figuren 1 und 2 ist schematisch ein erstes Ausführungsbeispiel der erfindungsgemäßen Schmelzspinnvorrichtung in mehreren Ansichten dargestellt. Fig. 1 zeigt das Ausführungsbeispiel in einer Seitenansicht und in Fig. 2 ist das Ausführungsbeispiel in einer Vorderansicht dargestellt. Soweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist, gilt die nachfolgende Beschreibung für beide Figuren.In the FIGS. 1 and 2 schematically a first embodiment of the inventive melt spinning device is shown in several views. Fig. 1 shows the embodiment in a side view and in Fig. 2 the embodiment is shown in a front view. Unless express reference is made to any of the figures, the following description applies to both figures.

Das Ausführungsbeispiel weist eine Spinneinrichtung 1, eine Abkühleinrichtung 3, eine Verstreckeinrichtung 4 sowie eine Aufwickeleinrichtung 22 auf, die untereinander angeordnet sind, um einen im wesentlichen vertikal ausgerichteten Fadenlauf zu erhalten.The embodiment comprises a spinning device 1, a cooling device 3, a stretching device 4 and a winding device 22, which are arranged one below the other to obtain a substantially vertically aligned yarn path.

Die Spinneinrichtung 1 weist einen Spinnbalken 9 auf, der an seiner Unterseite mehrere Spinndüsen 2 trägt.The spinning device 1 has a spinning bar 9, which carries a plurality of spinnerets 2 on its underside.

Wie aus der Darstellung in Fig. 2 hervorgeht, sind an dem Spinnbalken zwei Spinndüsen 2 gehalten, die jeweils als eine Doppeldüse 8.1 und 8.2 ausgebildet sind. Jede der am Spinnbalken 9 gehaltenen Doppeldüsen 8.1 und 8.2 sind jeweils über zwei separate Schmelzeleitungen mit einer Mehrfachpumpe 6 gekoppelt. Die Mehrfachpumpe 6 ist vorzugsweise als eine Planetenradpumpe ausgebildet, wobei jeder Doppeldüse 8.1 und 8.2 zwei separate Planetenradsätze zugeordnet sind. Die Mehrfachpumpe 6 ist über einen Pumpenantrieb 7 angetrieben. Die Zuführung einer Polymerschmelze erfolgt hierbei durch einen Schmelzezulauf 5, der mit der Mehrfachpumpe 6 gekoppelt ist.As from the illustration in Fig. 2 shows, two spinnerets 2 are held on the spinning beam, which are each formed as a double nozzle 8.1 and 8.2. Each of the double nozzles 8.1 and 8.2 held on the spinning beam 9 are each coupled to a multiple pump 6 via two separate melt lines. The multiple pump 6 is preferably designed as a planetary gear, each double nozzle 8.1 and 8.2 are assigned two separate planetary gear sets. The multiple pump 6 is driven by a pump drive 7. The feeding of a polymer melt takes place here through a melt inlet 5, which is coupled to the multiple pump 6.

Unterhalb der Spinneinrichtung 1 ist die Abkühleinrichtung 3 vorgesehen, die eine Blaskammer 10 aufweist, die mit einer hier nicht dargestellten Klimaeinrichtung verbunden ist. Innerhalb der Blaskammer 10 sind mehrere Kühlzylinder 11.1 und 11.2 angeordnet, die den Spinndüsen 2 zugeordnet sind. Die Kühlzylinder 11.1 und 11.2 weisen jeweils eine gasdurchlässige Zylinderwand auf, so dass ein in die Blaskammer 10 eingeführtes Kühlmedium gleichmäßig ins Innere der Kühlzylinder 11.1 und 11.2 eindringt.Below the spinning device 1, the cooling device 3 is provided, which has a blast chamber 10 which is connected to an air conditioning device, not shown here. Within the blast chamber 10, a plurality of cooling cylinders 11.1 and 11.2 are arranged, which are associated with the spinnerets 2. The cooling cylinders 11.1 and 11.2 each have a gas-permeable cylinder wall, so that a cooling medium introduced into the blow chamber 10 penetrates uniformly into the interior of the cooling cylinders 11.1 and 11.2.

Wie insbesondere aus der Darstellung in Fig. 2 hervorgeht, weist jeder der Kühlzylinder 11.1 und 11.2 im mittleren Bereich eine Trennwand 12 auf, durch welche zwei separate Kühlzonen in dem Kühlzylinder 11.1 und 11.2 gebildet sind. In jeder der Kühlzonen lässt sich somit ein durch eine der Doppeldüsen 8.1 und 8.2 extrudiertes Filamentbündel einführen.As in particular from the illustration in Fig. 2 shows, each of the cooling cylinder 11.1 and 11.2 in the middle region on a partition wall 12, are formed by which two separate cooling zones in the cooling cylinder 11.1 and 11.2. In each of the cooling zones, it is thus possible to introduce a filament bundle extruded through one of the double nozzles 8.1 and 8.2.

Die Ausbildung der Blaskammer 10 und der Kühlzylinder 11.1 und 11.2 ist beispielhaft. Grundsätzlich besteht auch die Möglichkeit, die Blaskammer 10 durch eine obere und eine untere Kammer zu bilden, die über ein Lochblech miteinander verbunden sind. Hierbei werden beide Kammern der Blaskammer durch einen Kühlzylinder durchdrungen, der in der oberen Kammer eine gasdurchlässige Wand und in der unteren Kammer eine geschlossene Wand aufweist. Die Verbindung mit der Klimaeinrichtung erfolgt dann über die untere Kammer der Blaskammer.The design of the blast chamber 10 and the cooling cylinder 11.1 and 11.2 is exemplary. In principle, it is also possible to form the blow chamber 10 through an upper and a lower chamber, which are connected to each other via a perforated plate. Here, both chambers of the blowing chamber are penetrated by a cooling cylinder having a gas-permeable wall in the upper chamber and a closed wall in the lower chamber. The connection with the air conditioning then takes place via the lower chamber of the blow chamber.

Alternativ besteht jedoch auch die Möglichkeit, die Kühlzylinder 11.1 und 11.2 durch eine quer zu den Spinndüsen 2 ausgerichteten Blaswand zu bilden, so dass ein quer gerichteter Kühlluftstrom erzeugbar ist.Alternatively, however, it is also possible to form the cooling cylinders 11.1 and 11.2 by a transverse to the spinnerets 2 aligned blowing wall, so that a transversely directed cooling air flow can be generated.

Wie aus den Darstellungen in Fig. 1 und Fig. 2 hervorgeht, münden die Kühlzylinder 11.1 und 11.2 in einen Kühlschacht 13, in welchem die Fäden zur Abkühlung geführt sind.As from the illustrations in Fig. 1 and Fig. 2 shows, the cooling cylinder 11.1 and 11.2 open into a cooling shaft 13, in which the threads are led to cool down.

Da jeder der extrudierten Multifilament-Fäden durch eine Vielzahl von Filamentsträngen gebildet ist, erfolgt am Auslass der Abkühleinrichtung 3 eine Zusammenführung der Filamente pro Faden. Hierzu sind mehrere Sammelfadenführer 14 und eine Präparationseinrichtung 15 vorgesehen. Die Präparationseinrichtung 15 ist in diesem Ausführungsbeispiel beispielhaft als eine Walzenpräparation gezeigt. Grundsätzlich können hierbei jedoch auch Stiftpräparationen verwendet werden.Since each of the extruded multifilament yarns is formed by a multiplicity of filament strands, a convergence of the filaments per yarn takes place at the outlet of the cooling device 3. For this purpose, several collection thread guides 14 and a preparation device 15 are provided. The preparation device 15 is shown by way of example in this embodiment as a roll preparation. In principle, however, pen preparations can also be used here.

Zum Abziehen und Verstrecken der extrudierten Fäden als eine Fadenschar ist die Verstreckeinrichtung 4 der Abkühleinrichtung 3 nachgeordnet. Die Verstreckeinrichtung 4 weist in diesem Ausführungsbeispiel zwei Galetteneinheiten 16.1 und 16.2 auf. Die Galetteneinheiten 16.1 und 16.2 sind identisch ausgebildet und bestehen in diesem Ausführungsbespiel aus eine angetriebenen Galette 17 und einer drehbar gelagerten Beilaufrolle 18. Die Galette 17 wird durch einen Galettenantrieb 31 angetrieben. Die Fäden werden als eine Fadenschar 33 mit mehreren Umschlingungen an den Galetteneinheiten 16.1 und 16.2 geführt. Zwischen den Galetten 17 der Galetteneinheiten 16.1 und 16.2 ist hierbei eine Differenzgeschwindigkeit eingestellt, um die Fäden der Fadenschar 33 zu verstrecken.For stripping and stretching the extruded threads as a group of threads, the drawing device 4 is arranged downstream of the cooling device 3. The stretching device 4 has in this embodiment, two galette units 16.1 and 16.2. The godet units 16.1 and 16.2 are formed identically and consist in this exemplary embodiment of a driven godet 17 and a rotatably mounted Beilaufrolle 18. The galette 17 is driven by a godet drive 31. The threads are guided as a yarn sheet 33 with several wraps on the godet units 16.1 and 16.2. Between the godets 17 of the godet units 16.1 and 16.2 in this case a differential speed is set to stretch the threads of the yarn sheet 33.

Bei Übergang von der Abkühleinrichtung 3 zu der Verstreckeinrichtung 4 ist eine erste Drehung der Fadenlaufebene um 90° erforderlich, da die durch die Spinndüsen aufgespannte Fadenlaufebene um 90° versetzt zu der durch die Galetteneinheiten 16.1 und 16.2 gebildete Fadenlaufebene verläuft. Als Fadenlaufebene wird dabei die Ebene bezeichnet, in welcher die Fäden der Fadenschar 33 nebeneinander geführt sind.In the transition from the cooling device 3 to the drawing device 4, a first rotation of the thread running plane by 90 ° is required, since the spanned by the spinneret thread running plane 90 ° offset from the formed by the godet units 16.1 and 16.2 thread running plane. As a thread running plane while the plane is referred to, in which the threads of the yarn sheet 33 are guided side by side.

Zur Überführung der Fadenschar ist zwischen der Präparationseinrichtung 15 und der ersten Galette 17 der Galetteneinheit 16.1 der Verstreckeinrichtung 4 ein Führungsmittel 19 vorgesehen, durch welche die Fadenschar verdreht wird und gleichzeitig die Fäden auf einen Behandlungsabstand zueinander geführt werden.To transfer the group of threads, a guide means 19 is provided between the preparation device 15 and the first godet 17 of the godet unit 16.1 of the drawing device 4, by which the yarn sheet is twisted and at the same time the threads are guided to a treatment distance from each other.

Wie aus den beiden Darstellungen des ersten Ausführungsbeispiels hervorgeht, ist der Verstreckeinrichtung 4 eine Führungsgalette 20.1 nachangeordnet. Die Führungsgalette 20.1 ist der letzten Galette 17 der Galetteneinheit 16.2 nachgeordnet, um die Fadenschar 33 von der Galetteneinheit 16.2 abzuziehen. Hierzu ist die Führungsgalette 20.1 axial quer zur Galette 17 der Galetteneinheit 16.2 ausgerichtet, so dass beim Übergang die Fäden durch eine Drehung der Fadenlaufebene um 90° mit einfacher Teilumschlingung an der Führungsgalette führbar sind.As can be seen from the two illustrations of the first embodiment, the drawing device 4 is a guide godet 20.1 nachangeordnet. The guide godet 20.1 is the last galette 17 of the godet unit 16.2 arranged downstream to subtract the yarn sheet 33 of the godet unit 16.2. For this purpose, the guide godet 20.1 is aligned axially transversely to the godet 17 of the godet 16.2, so that during the transition the threads can be guided by a rotation of the thread running plane through 90 ° with simple Teilumschlingung on the guide godet.

Die Führungsgalette 20.1 ist an einem Galettenträger 34 gehalten, der sich an einem Maschinengestell 30 der Aufwickeleinrichtung 22 abstütz. Ein der Führungsgalette 20.1 zugeordnete Galettenantrieb 31 wird an der gegenüberliegenden Seite des Galettenträgers 34 gehalten.The guide godet 20.1 is held on a godet carrier 34, which is supported on a machine frame 30 of the take-up device 22. One of the guide godet 20.1 associated godet drive 31 is held on the opposite side of the godet carrier 34.

Der Führungsgalette 20.1 ist wie aus der Darstellung in Fig. 1 hervorgeht, eine zweite Führungsgalette 20.2 zugeordnet, die an dem Galettenträger 34 seitlich neben mehreren Wickelstellen 23.1 bis 23.4 der Aufwickeleinrichtung 22 angeordnet ist. Zwischen den Führungsgaletten 20.1 und 20.2 ist eine Verwirbelungseinrichtung 21 vorgesehen, durch welche die Fäden der Fadenschar 33 separat voneinander behandelbar sind.The guide godet 20.1 is as shown in FIG Fig. 1 shows, associated with a second Führungsgalette 20.2, which is arranged on the godet carrier 34 laterally next to several winding points 23.1 to 23.4 of the winding device 22. Between the Führungsgaletten 20.1 and 20.2, a swirling device 21 is provided, through which the threads of the yarn sheet 33 are separately treatable.

Die Aufwickeleinrichtung 22 weist mehrere Wickelstellen 23.1 bis 23.4 auf, in denen die Fäden der Fadenschar 33 jeweils zu einer Spule 26 gewickelt werden. Die Wickelstellen 23.1 bis 23.4 sind identisch ausgebildet und weisen jeweils eine Umlenkrolle 27 und eine Changiereinheit 28 auf. Die Spulen 23 werden dabei gleichzeitig an eine Spulspindel 24.1 oder 24.2 gewickelt, die auskragend an einem Spulrevolver 25 gehalten sind und abwechselnd in einen Betriebsbereich und einen Wechselbereich geführt werden. Zur Ablage der Fäden der Fadenschar 33 auf die jeweiligen Spulen 26 ist eine Andrückwalze 29 vorgesehen, die am Umfang der Spulen 26 anliegt. Der Spulrevolver 25 sowie die Andrückwalze 29 sind beweglich in dem Maschinengestell 30 gehalten.The winding device 22 has a plurality of winding points 23.1 to 23.4, in which the threads of the yarn sheet 33 are each wound into a coil 26. The winding points 23.1 to 23.4 are identical and each have a deflection roller 27 and a traversing unit 28. The coils 23 are simultaneously wound on a winding spindle 24.1 or 24.2, which are held cantilevered on a winding turret 25 and are alternately guided in an operating range and a change range. For depositing the threads of the yarn sheet 33 on the respective spools 26, a pressure roller 29 is provided, which rests on the circumference of the coil 26. The winding turret 25 and the pressure roller 29 are movably held in the machine frame 30.

Die Antriebe der Aufwickeleinrichtung 22 sind hier nicht dargestellt, da derartige in der Fachwelt auch als Spulrevolver bezeichnete Aufwickeleinrichtungen hinlänglich bekannt sind. Hierbei bilden die Galettenantriebe 31 der Führungsgalette 20.1 und 20.2 vorteilhaft eine Steuereinheit, die gemeinsam elektrisch versorgt und gesteuert werden.The drives of the take-up device 22 are not shown here since such winding devices, which are also referred to in the art as winding turrets, are well known. In this case, the godet drives 31 of the guide godet 20.1 and 20.2 advantageously form a control unit, which are jointly supplied and controlled electrically.

Bei dem in Fig. 1 und 2 dargestellten Ausführungsbeispiel ist zur Erläuterung der Funktion der Fadenlauf der Fadenschar 33 eingezeichnet. Dabei wird durch die beiden Doppeldüsen 8.1 und 8.2 aus einer Polymerschmelze eine Mehrzahl von feinen Filamentsträngen extrudiert, die nach dem Abkühlen durch Zusammenführen und Präparieren zu insgesamt vier Multifilamentfäden zusammengeführt werden. Grundsätzlich besteht die Möglichkeit, dass neben der Präparation auch eine Vorverwirbelung der Filamente erfolgt, um einen für die Behandlung der Fäden erforderlichen Fadenzusammenschluss zu bilden.At the in Fig. 1 and 2 illustrated embodiment is shown to explain the function of the yarn path of the yarn sheet 33. In this case, a plurality of fine filament strands are extruded through the two double nozzles 8.1 and 8.2 from a polymer melt, which are combined after cooling by merging and dissection to a total of four multifilament yarns. In principle, there is the possibility that, in addition to the preparation, a preliminary swirling of the filaments takes place in order to form a thread combination necessary for the treatment of the threads.

Anschließend wird die aus den vier Fäden gebildete Fadenschar 33 durch die erste Galette 17 der Galetteneinheit 16.1 von den Spinndüsen 2 abgezogen, wobei die Fadenschar aus einer ersten Fadenlaufebene, die durch die Reihe der Spinndüsen 2 aufgespannt ist, in eine um 90° versetzte Fadenlaufebene überführt. Die zweite Fadenlaufebene ist durch die axiale Ausrichtung der Galetten 17 der Galetteneinheiten 16.1 und 16.2 quer zu der Reihe der Spinndüsen 2 bestimmt.Subsequently, the group of threads 33 formed by the four threads is withdrawn from the spinnerets 2 by the first godet 17 of the godet unit 16.1, wherein the group of threads is transferred from a first thread running plane, which is spanned by the row of spinnerets 2, into a thread running plane offset by 90 ° , The second thread running plane is determined by the axial orientation of the godets 17 of the godet units 16.1 and 16.2 transverse to the row of spinnerets 2.

In der Verstreckeinrichtung 4 wird die Fadenschar 33 durch Differenzgeschwindigkeiten der Galetteneinheiten 16.1 und 16.2 verstreckt. Die Galetten 17 der Galetteneinheiten 16.1 und 16.2 sind hierzu vorteilhaft beheizt ausgeführt.In the drawing device 4, the yarn sheet 33 is stretched by differential speeds of the godet units 16.1 and 16.2. The godets 17 of the godet units 16.1 and 16.2 are designed to be advantageous heated.

An dieser Stelle sei ausdrücklich erwähnt, dass die Ausbildung der Galetteneinheiten 16.1 und 16.2 beispielshaft ist. Grundsätzlich können die Galetteneinheiten 16.1 und 16.2 alternativ auch durch zwei angetriebene Galetten gebildet sein, die beheizte Führungsmäntel aufweisen. Darüber hinaus könnten auch mehrere Galetteneinheiten verwendet werden, die wahlweise aus Galetten mit Beilaufrolle, aus mehreren Galetten oder aus Einzelgaletten bestehen.It should be expressly mentioned at this point that the formation of the godet units 16.1 and 16.2 is exemplary. In principle, the godet units 16.1 and 16.2 can alternatively also be formed by two driven godets having heated guide shells. In addition, several galette units could be used, which optionally consist of godets with bathe, multiple godets or single godets.

Nach dem Verstrecken der Fadenschar 33 wird die Fadenschar 33 durch die der Verstreckeinrichtung 4 nachgeordnete Führungsgalette 20.1 abgezogen. Hierbei wird die Fadenschar aus der zur Behandlung aufgespannten Fadenlaufebene herausgeführt und in eine um 90° verdrehte Führungseben überführt, die die axiale Ausrichtung der Führungsgalette 20.1 bestimmt ist, wobei die Führungsgalette 20.1 im Wesentlichen quer zu den Galetten 17 der Galetteneinheiten 16.1 und 16.2 ausgerichtet ist. Die Fadenstrecke zwischen der Galetteneinheit 16.2 und der Führungsgalette 20.1 lässt sich vorteilhaft zu einer Schrumpfbehandlung nutzen, wobei die Führungsgalette 20.1 unabhängig von der Galetteneinheit 16.2 angetrieben wird. Zudem besteht die Möglichkeit, dass die Führungsgalette 20.1 beheizt ausgeführt ist.After stretching the yarn sheet 33, the yarn sheet 33 is withdrawn by the Verstreckeinrichtung 4 downstream Führungsgalette 20.1. Here, the group of threads is led out of the spanned for treatment thread running plane and transferred to a twisted by 90 ° guide level, which is the axial orientation of the Führungsgalette 20.1 is determined, the Führungsgalette 20.1 is aligned substantially transversely to the godets 17 of the godet 16.1 and 16.2. The yarn path between the godet unit 16.2 and the guide godet 20.1 can advantageously be used for shrinking treatment, the guide godet 20.1 being driven independently of the godet unit 16.2. In addition, there is the possibility that the guide godet 20.1 is designed to be heated.

Zur weiteren Behandlung wird die Fadenschar 33 der Verwirbelungseinrichtung 21 zugeführt, die zwischen den Führungsgaletten 20.1 und 20.2 gehalten ist. Hierbei lässt sich eine durch unterschiedliche Umfangsgeschwindigkeiten der Führungsgaletten 20.1 und 20.2 vorteilhafte Fadenspannungen zur Verwirbelung der Fäden der Fadenschar 33 einstellen. Hierzu ist die Führungsgalette 20.2 durch den Galettenantrieb 31 angetrieben, so dass darüber hinaus eine unabhängige Aufwickelspannung an den Fäden der Fadenschar 33 erzeugbar ist.For further treatment, the yarn sheet 33 is supplied to the swirling device 21, which is held between the guide godets 20.1 and 20.2. In this case, a yarn tension that is advantageous due to different peripheral speeds of the guide godets 20.1 and 20.2 can be adjusted for swirling the yarns of the yarn sheet 33. For this purpose, the guide godet 20.2 is driven by the godet drive 31, so that beyond an independent Aufwickelspannung on the threads of the yarn sheet 33 can be generated.

Am Ende werden die Fäden der Fadenschar 33 auf die einzelnen Wickelstellen 23.1 und 23.4 verteilt und zu jeweils einer Spule 26 gewickelt. Aufgrund der Gleichbehandlung durch mehrere sanfte Umlenkungen durch drehende Umlenkmittel weist jeder Faden der Fadenschar 33 eine im wesentlichen identische Charakteristik auf, so dass die Spulen mit im wesentlichen identischen Aufwickelspannungen erzeugbar sind.At the end, the threads of the yarn sheet 33 are distributed to the individual winding points 23.1 and 23.4 and wound into a respective coil 26. Due to the equal treatment by a plurality of gentle deflections by rotating deflection, each thread of the yarn sheet 33 has a substantially identical characteristic, so that the coils with substantially identical winding voltages can be generated.

Die bei dem Ausführungsbeispiel nach Fig. 1 und 2 gewählte Anzahl der Fäden, die gleichzeitig extrudiert, verstreckt und aufgewickelt werden, ist beispielhaft. Grundsätzlich werden üblicherweise mehr als vier Fäden pro Schmelzspinnvorrichtung in einer Spinnanlage erzeugt. Die Anzahl der Fäden ist jedoch für die Erläuterung der Erfindung unerheblich.The in the embodiment according to Fig. 1 and 2 chosen number of threads that are extruded, stretched and wound simultaneously is exemplary. In principle, usually more than four threads per Melt spinning device produced in a spin line. However, the number of threads is irrelevant to the explanation of the invention.

In Fig. 3 ist eine weitere Variante der erfindungsgemäßen Schmelz spinnvorrichtung schematisch in einer Seitenansicht dargestellt. Das Ausführungsbeispiel ist im Wesentlichen identisch zu dem Ausführungsbeispiel nach Fig. 1, so dass an dieser Stelle nur die Unterschiede erläutert werden und ansonsten Bezug zu der vorgenannten Beschreibung genommen wird.In Fig. 3 is a further variant of the inventive melt spinning device shown schematically in a side view. The exemplary embodiment is essentially identical to the exemplary embodiment according to FIG Fig. 1 , so that at this point only the differences will be explained and otherwise reference is made to the above description.

Bei dem in Fig. 3 dargestellten Ausführungsbeispiel der erfindungsgemäßen Vorrichtung ist zur Führung der Fadenschar 33 zwischen der Verstreckeinrichtung 4 und der Aufwickeleinrichtung 22 ein Führungsmittel 32 und eine Führungsgalette 20 angeordnet. Die Führungsgalette 20 ist an dem Galettenträger 34 seitlich neben den Wickelstellen 23.1 und 23.4 gehalten, so dass die mit einer Teilumschlingung an der Führungsgalette 20 geführten Fäden der Fadenschar 33 direkt den Wickelstellen 23.1 bis 23.4 zuführbar sind.At the in Fig. 3 illustrated embodiment of the device according to the invention, a guide means 32 and a guide godet 20 is arranged to guide the yarn sheet 33 between the drawing device 4 and the take-up device 22. The guide godet 20 is held on the godet carrier 34 laterally next to the winding stations 23.1 and 23.4, so that the guided with a Teilumschlingung on the guide godet 20 threads of the yarn sheet 33 directly to the winding stations 23.1 to 23.4 can be fed.

Um die Fäden der Fadenschar nach Ablauf von der Galetteneinheit 16.2 in der Fadenlaufebene um 90° zu verdrehen, ist das Führungsmittel 32 vorgesehen, so dass der Ablauf der Fadenschar an der Galetteneinheit 16.2 sowie der Zulauf der Fadenschar an der Führungsgalette 20 durch das Führungsmittel 32 stabilisiert werden kann. Das Verdrehen der Fadenschar 33 erfolgt dabei ohne Umlenkung und Aufspreizungen in geradem Fadenlauf.To rotate the threads of the yarn sheet after the expiry of the godet unit 16.2 in the thread running plane by 90 °, the guide means 32 is provided so that the flow of the yarn sheet on the godet unit 16.2 and the feed of the yarn sheet on the guide godet 20 stabilized by the guide means 32 can be. The twisting of the yarn sheet 33 takes place without deflection and spreading in a straight yarn path.

Die Funktion des in Fig. 3 dargestellten Ausführungsbeispiels ist identisch zu der Funktion des Ausführungsbeispiels nach Fig. 1 und 2, so dass an dieser Stelle zu der vorgenannten Beschreibung Bezug genommen wird und keine weitere Erläuterung erfolgt.The function of in Fig. 3 illustrated embodiment is identical to the function of the embodiment according to Fig. 1 and 2 , so that at this point to the above description, reference is made and no further explanation is made.

Das in Fig. 3 dargestellte Umlenkmittel zur Überführung der Fadenschar von der Verstreckeinrichtung zu der Aufwickeleinrichtung lässt sich vorteilhaft auch in dem Ausführungsbeispiel nach Fig. 1 integrieren. Ebenso besteht die Möglichkeit, das in Fig. 3 dargestellte Ausführungsbeispiel der Schmelzspinnvorrichtung ohne ein zusätzliches Führungsmittel auszuführen.This in Fig. 3 shown deflection means for the transfer of the yarn sheet from the drawing device to the winding device can be advantageous also in the embodiment according to Fig. 1 integrate. It is also possible to do so in Fig. 3 illustrated embodiment of the melt spinning device without an additional guide means to perform.

In der Fig. 4 ist schematisch ein weiteres Ausführungsbeispiel der erfindungsgemäßen Schmelzspinnvorrichtung in einer Vorderansicht dargestellt. Das Ausführungsbeispiel ist im Wesentlichen identisch zu dem vorgenannten Ausführungsbeispiel nach Fig. 3, so dass zur Vermeidung von Wiederholungen nur die Unterschiede erläutert werden und ansonsten Bezug zu der vorgenannten Beschreibung genommen wird.In the Fig. 4 schematically another embodiment of the inventive melt spinning device is shown in a front view. The embodiment is essentially identical to the aforementioned embodiment according to Fig. 3 , so that only the differences are explained to avoid repetition and otherwise reference is made to the above description.

Bei dem in Fig. 4 dargestellten Ausführungsbeispiel ist die Aufwickeleinrichtung 22 durch zwei nebeneinander angeordnete Aufspulvorrichtungen 35.1 und 35.2 gebildet. Die Aufspulvorrichtungen 35.1 und 35.2 sind spiegelsymmetrisch zueinander angeordnet und besitzen jeweils den gleichen Aufbau. Jede der Aufspulvorrichtungen 35.1 und 35.2 weist so mehrere Wickelstellen 23.1 bis 23.4 auf. Die in Fig. 3 gezeigte Aufwickeleinrichtung 22 stellt somit die Seitenansicht einer der Aufspulvorrichtungen 35.1 und 35.2 dar. Insoweit wird zu der in Fig. 3 gemachten Beschreibung Bezug genommen.At the in Fig. 4 illustrated embodiment, the winding device 22 is formed by two juxtaposed winding devices 35.1 and 35.2. The winding devices 35.1 and 35.2 are arranged mirror-symmetrically to each other and each have the same structure. Each of the winding devices 35.1 and 35.2 thus has several winding points 23.1 to 23.4. In the Fig. 3 The winding device 22 shown thus represents the side view of one of the winding devices 35.1 and 35.2 Fig. 3 reference made.

Die Aufspulvorrichtungen 35.1 und 35.2 werden synchron betrieben, um die Fäden der Fadenschar 33 jeweils zu Spulen zu wickeln. Die Fadenschar 33 wird über eine der Aufwickeleinrichtung 22 vorgeordnete Führungsgalette 20 zugeführt. Die Führungsgalette 20 ist hierzu in der Mitte der beiden Aufspulvorrichtungen 35.1 und 35.2 an einem Trägergestell 37 oberhalb der Aufspulvorrichtungen 35.1 und 35.2 gehalten. Die Führungsgalette 20 ist auskragend an dem Galettenträger 34 angeordnet und über einen Elektromotor angetrieben.The winding devices 35.1 and 35.2 are operated synchronously in order to wind the threads of the yarn sheet 33 in each case to coils. The yarn sheet 33 is fed via a winding device 22 upstream Führungsgalette 20. The guide godet 20 is held for this purpose in the middle of the two winding devices 35.1 and 35.2 on a support frame 37 above the winding devices 35.1 and 35.2. The guide godet 20 is cantilevered on the godet carrier 34 and driven by an electric motor.

Nach Ablauf der Fäden der Fadenschar 33 von der Führungsgalette 20 wird die Fadenschar geteilt, so dass jede Aufspulvorrichtung 35.1 und 35.2 die gleiche Anzahl von Fäden zu Spulen wickelt.After the threads of the yarn sheet 33 from the guide godet 20, the yarn sheet is divided, so that each winding device 35.1 and 35.2 winds the same number of threads to coils.

An dem Trägergestell 37 ist oberhalb der Aufspulvorrichtungen 35.1 und 35.2 eine Verstreckeinrichtung 4 angeordnet. Die Verstreckeinrichtung 4 wird in diesem Ausführungsbeispiel ebenfalls durch zwei Galetteneinheiten 16.1 und 16.2 gebildet, die jeweils zwei angetriebene Galetten 17 aufweisen. Die Galetten 17 der Galetteneinheiten 16.1 und 16.2 werden bevorzugt als Galettenduos betrieben, so dass zwischen den Galetteneinheiten 16.1 und 16.2 eine Differenzgeschwindigkeiten zum Verstrecken der Fäden einstellbar ist.On the support frame 37, a drawing device 4 is arranged above the winding devices 35.1 and 35.2. The stretching device 4 is also formed in this embodiment by two godet units 16.1 and 16.2, each having two driven godets 17. The godets 17 of the godet 16.1 and 16.2 are preferably operated as Galettenduos, so that between the godet units 16.1 and 16.2, a differential speeds for drawing the threads is adjustable.

Die Galetten 17 der Galetteneinheiten 16.1 und 16.2 sind mit ihren Achsen gleich zu den Spulspindeln 24.1 und 24.2 der beiden Aufspulvorrichtuen 35.1 und 35.2 ausgerichtet. Demgegenüber ist die zwischen der Galetteneinheit 16.2 und der Aufwickeleinrichtung 22 angeordnete Führungsgalette 20 quer gerichtet, so dass beim Übergang der Fäden von der Galetteneinheit 16.2 zu der Führungsgalette 20 die Fadenschar in ihrer Fadenlaufebene um einen Winkel im Bereich von 90° verdreht wird. Hierbei ist zwischen der Galetteneinheit 16.2 und der Führungsgalette 20 kein weiteres Führungsmittel vorgesehen.The godets 17 of the godet 16.1 and 16.2 are aligned with their axes equal to the winding spindles 24.1 and 24.2 of the two Aufspulvorrichtuen 35.1 and 35.2. In contrast, arranged between the godet unit 16.2 and the winding device 22 Führungsgalette 20 is directed transversely, so that the thread group is rotated in its yarn running plane by an angle in the range of 90 ° when passing the threads of the godet unit 16.2 to the guide godet 20. Here, no further guide means is provided between the godet unit 16.2 and the guide godet 20.

Die Galetteneinheiten 16.1 und 16.2 sind in diesem Ausführungsbeispiel jeweils in Galettenboxen 36.1 und 36.2 angeordnet. So werden bevorzugt beheizte Galetten 17 in den Galetteneinheiten 16.1 und 16.2 verwendet, so dass innerhalb der Galettenboxen 36.1 und 36.2 eine zur Behandlung der Fäden thermisch isolierte Umgebung entsteht.The godet units 16.1 and 16.2 are arranged in each case in godet boxes 36.1 and 36.2 in this embodiment. Thus, heated godets 17 are preferably used in the godet units 16.1 and 16.2, so that within the godet boxes 36.1 and 36.2 a thermally insulated environment for the treatment of the threads arises.

Die Spinneinrichtung 1 und die Abkühleinrichtung 3 ist identisch zu dem Ausführungsbeispiel nach Fig. 1 und 2 ausgebildet, wobei die Anzahl der Spinndüsen verdoppelt ist. So sind insgesamt vier Doppeldüsen 8.1 bis 8.4 vorgesehen, um pro Spinndüsenplatz zwei Fäden gleichzeitig zu extrudieren. Zur weiteren Erläuterung wird an dieser Stelle Bezug zu der vorhergehenden Beschreibung zu Fig. 2 genommen.The spinning device 1 and the cooling device 3 is identical to the embodiment according to Fig. 1 and 2 formed, wherein the number of spinnerets is doubled. So are a total of four double nozzles 8.1 bis 8.4 provided to extrude two threads per spinneret place simultaneously. For further explanation, reference is made to the preceding description at this point Fig. 2 taken.

Die Spinndüsen 2 sind bei dem Ausführungsbeispiel nach Fig. 4 ebenfalls in einer reihenförmigen Anordnung ausgerichtet, die quer zu den Galettenachsen der Galetten 17 verläuft. Insoweit werden die Fäden der Fadenschar 33 aus einer durch die Düsen bestimmten Spinnebene in eine durch die Galetteneinheiten 16.1 und 16.2 bestimmte Behandlungsebene überführt. Dabei ist ein Führungsmittel 19 vorgesehen, um die Fadenlaufebene der Fadenschar um einen Winkel im Bereich von 90° zu verdrehen. Das Führungsmittel 19 ist der Verstreckeinrichtung 4 unmittelbar vorgeordnet. Hierbei werden die Fäden gemeinsam als eine Fadenschar parallel nebeneinander geführt.The spinnerets 2 are in the embodiment according to Fig. 4 also aligned in a row-shaped arrangement which extends transversely to the godet axes of the godets 17. In that regard, the threads of the group of yarns 33 are transferred from a spinner level determined by the nozzles into a treatment level determined by the godet units 16.1 and 16.2. In this case, a guide means 19 is provided to rotate the yarn running plane of the yarn sheet by an angle in the range of 90 °. The guide means 19 is the Verstreckeinrichtung 4 immediately upstream. Here, the threads are performed together as a group of threads parallel to each other.

Zwischen der Verstreckeinrichtung 4 und der Spinneinrichtung 1 ist ein Sammelfadenführer 14 sowie eine Präparationseinrichtung 15 angeordnet, um die pro Spinndüse extrudierten Filamentstränge zu Fäden zusammenzuführen.Between the drawing device 4 and the spinning device 1, a collecting thread guide 14 and a preparation device 15 are arranged in order to bring together the filament strands extruded per spinneret into threads.

Das in Fig. 4 dargestellte Ausführungsbeispiel stellt eine besonders kompakte Anordnung zur Herstellung einer Vielzahl von Fäden innerhalb einer Spinnstelle dar. Die Funktion des in Fig. 4 dargestellten Ausführungsbeispiels ist identisch zu der Funktion der vorgenannten Ausführungsbeispiele, so dass hierzu keine weitere Erläuterung erfolgt.This in Fig. 4 illustrated embodiment represents a particularly compact arrangement for producing a plurality of threads within a spinning station. The function of in Fig. 4 illustrated embodiment is identical to the function of the aforementioned embodiments, so that there is no further explanation.

Die in den Fig. 1 bis 4 dargestellten Ausführungsbeispiele sind im Aufbau und Anordnung der Verstreckeinrichtung beispielhaft. Grundsätzlich besteht die Möglichkeit, zusätzliche Behandlungsschritte und Behandlungsaggregate im Bereich zwischen der Spinneinrichtung und der Aufwickeleinrichtung zu integrieren.The in the Fig. 1 to 4 illustrated embodiments are exemplary in construction and arrangement of the stretching device. In principle, it is possible to integrate additional treatment steps and treatment units in the region between the spinning device and the take-up device.
