Description

Die Erfindung betrifft eine Texturiermaschine zum Falschdralltexturieren eines Fadens gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a texturing machine for false twist texturing of a thread according to the preamble of claim 1.

Eine gattungsgemäße Texturiermaschine ist aus der EP 0 853 150 bekannt.A generic texturing machine is known from EP 0 853 150.

Bei der bekannten Texturiermaschine wird ein zugeliefertes Glattgam durch einen Falschdrallprozeß texturiert. Hierzu wird der durch ein Falschdrallaggregat erzeugte Falschdrall in dem Faden durch eine Wärmebehandlung und einer anschließenden Abkühlung fixiert. Zum Abkühlen des falschgedrallten Fadens wird ein Kühlrohr verwendet, an dessen Oberfläche der Faden wendelförmig geführt ist. Um in Abhängigkeit vom Gamtyp die Kühlfläche an der Oberfläche des Kühlrohres zu verändern, besitzt die bekannte Texturiermaschine mehrere bewegliche Fadenführer, die die Steigung der wendelförmigen Kühlstrecke am Umfang des Kühlrohres verändern. Als Kühlstrecke wird der sich am Umfang des Kühlrohres einstellender Fadenlauf bezeichnet. Um bei Fäden mit kleinen Fadentitern keine zu intensive Kühlung zu erhalten, wird ein besonders flacher Steigungswinkel der wendelförmigen Kühlstrecke am Umfang des Kühlrohres eingestellt. Damit verringert sich jedoch gleichzeitig der Grad der Umschlingung an dem Kühlrohr. Es tritt das Problem ein, daß die vom Falschdrallaggregat erzeugten hochdynamischen Drallschwingungen im Faden, die sich mit dem Falschdrall entgegen den Fadenlauf fortpflanzen, unzureichend in der Kühlzone abgebaut werden können. Die Drallschwingungen pflanzen sich im Faden somit bis in die Heizzone zurück und führen zu einem die Wärmebehandlung negativ beeinflussenden unruhigen Fadenlauf.In the known texturing machine, a supplied plain yarn is textured by a false twisting process. For this purpose, the false twist generated by a false twist unit is fixed in the thread by a heat treatment and a subsequent cooling. To cool the false-twisted thread, a cooling tube is used, on the surface of which the thread is guided helically. In order to change depending on the Gamtyp the cooling surface on the surface of the cooling tube, the known texturing machine has a plurality of movable thread guides that change the slope of the helical cooling section on the circumference of the cooling tube. As a cooling section of the adjusts itself on the circumference of the cooling tube yarn path. In order to obtain in threads with small Fadentitern not too intense cooling, a particularly shallow pitch angle of the helical cooling section is set at the periphery of the cooling tube. At the same time, this reduces the degree of wrap around the cooling tube. The problem arises that the highly dynamic swirl vibrations generated by the false twist unit in the yarn, which propagate with the false twist counter to the yarn path, can be insufficiently reduced in the cooling zone. The swirl vibrations thus replicate in the thread back into the heating zone and lead to a heat treatment negatively affecting restless yarn path.

Es ist Aufgabe der Erfindung, eine gattungsgemäße Texturiermaschine der eingangs genannten Art derart auszubilden, daß eine Beeinflussung der Kühlwirkung an dem Kühlrohr ohne wesentliche Veränderung der wendelförmigen Kühlstrecke möglich ist.It is an object of the invention to form a generic texturing machine of the type mentioned in such a way that an influence of the Cooling effect on the cooling tube without significant change in the helical cooling path is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen dem Einlauffadenführer und dem Auslauffadenführer ein Fadenheber angeordnet ist, durch welchen der Faden innerhalb der Kühlstrecke über eine Teillänge ohne Kontakt am Umfang des Kühlrohres geführt ist. Auf dem Teilstück der Kühlstrecke, in welchem der Faden von der Oberfläche des Kühlrohres abgehoben ist, findet keine intensive Kühlung des Fadens statt. Damit kann vorteilhaft der Grad der Kühlung innerhalb der Kühlstrecke eingestellt werden. Ein besonderer Vorteil der Erfindung liegt darin, daß die zum Abbau von Drallschwingungen erforderlichen Mindestumschlingungen an dem Kühlrohr erhalten bleiben. Obwohl sich das innerhalb der Kühlstrecke geführte Fadenstück durch Abheben des Fadens verlängert, wird eine schwächere Abkühlung erreicht. Insbesondere lassen sich somit Fäden mit feinen Titern vorteilhaft texturieren.This object is achieved in that between the inlet yarn guide and the outlet yarn guide a thread lifter is arranged, through which the thread is guided within the cooling section over a partial length without contact on the circumference of the cooling tube. On the section of the cooling section, in which the thread is lifted from the surface of the cooling tube, there is no intensive cooling of the thread. This can advantageously be set the degree of cooling within the cooling section. A particular advantage of the invention is that the minimum Umschlingungen required to reduce swirl vibrations remain on the cooling tube. Although the length of thread guided inside the cooling section is lengthened by lifting off the thread, a weaker cooling is achieved. In particular, threads with fine titers can thus advantageously be textured.

Gemäß einer vorteilhaften Weiterbildung der Erfindung läßt sich der Fadenheber auf einfache Weise durch einen Halter und einen Fadenführer bilden, wobei der Halter den Fadenführer mit Abstand zu dem Umfang des Kühlrohres hält. Damit wird ein örtlich begrenztes Abheben des Fadens von der Oberfläche des Kühlrohres ermöglicht.According to an advantageous embodiment of the invention, the thread lifter can be easily formed by a holder and a thread guide, wherein the holder holds the thread guide at a distance from the circumference of the cooling tube. This allows a localized lifting of the thread from the surface of the cooling tube.

Da bei veränderter Steigung der wendelförmigen Kühlstrecke die relative Fadenposition am Umfang des Kühlrohres sich verändert, wird gemäß einer vorteilhaften Weiterbildung vorgeschlagen, den Halter zur Veränderung der Position des Fadenführers relativ zum Kühlrohr in axialer und / oder radialer Richtung verstellbar auszubilden. Damit läßt sich der Faden an beliebiger Stelle der Kühlstrecke von der Oberfläche des Kühlrohres lösen.Since with a changed pitch of the helical cooling section, the relative thread position on the circumference of the cooling tube changes, it is proposed according to an advantageous development, the holder for changing the position of the yarn guide relative to the cooling tube in the axial and / or radial direction adjustable form. Thus, the thread can be solved at any point of the cooling section of the surface of the cooling tube.

Eine besonders einfache und sehr effektive Ausführungsvariante ist dadurch gegeben, daß der Halter ringförmig ausgebildet ist und auf das Kühlrohr aufgesteckt ist. Dabei ist der Fadenführer durch eine Nut am Umfang des Halters gebildet.A particularly simple and very effective embodiment is given by the fact that the holder is annular and on the cooling tube is plugged. The thread guide is formed by a groove on the circumference of the holder.

Die Weiterbildung, bei welcher der Fadenheber durch ein Ringsegment mit einer äußeren Führungskante zur Führung des Fadens gebildet ist, zeichnet sich durch eine noch höhere Flexibilität in der Fadenführung aus.The development in which the thread lifter is formed by a ring segment with an outer leading edge for guiding the thread, characterized by an even higher flexibility in the thread guide.

Das Ringsegment, daß am Umfang des Küblrohres angeordnet ist, kann dabei eine derartige Form aufweisen, daß der zwischen der Führungskante und der Oberfläche des Kühlrohres gebildete Fadenabstand in Umfangsrichtung des Kühlrohres ungleich groß ist. Damit besteht die Möglichkeit, die Teillänge, in welcher der Faden keinen Kontakt zum Kühlrohr hat, möglichst groß zu gestalten. Andererseits läßt sich durch Vergrößerung des Abstandes zwischen der Führungskante und der Oberfläche des Kühlrohres eine zusätzlich intensive Umschlingungsreibung an dem Faden erzeugen, was vorteilhaft zum Abbau der Drallschwingungen in dem Faden führt.The ring segment, which is arranged on the circumference of the Küblrohres, may have a shape such that the thread spacing formed between the leading edge and the surface of the cooling tube in the circumferential direction of the cooling tube is unequal size. This makes it possible to make the partial length, in which the thread has no contact with the cooling tube, as large as possible. On the other hand, can be produced by increasing the distance between the leading edge and the surface of the cooling tube, an additional intensive wrap friction on the thread, which advantageously leads to the reduction of the swirl vibrations in the thread.

Das Ringsegment ist dabei vorteilhaft am Umfang des Kühlrohres in axialer Richtung und / oder radialer Richtung verstellbar ausgeführt.The ring segment is advantageously designed to be adjustable on the circumference of the cooling tube in the axial direction and / or radial direction.

Um die Fadenspannung innerhalb der Falschdrallzone über das durch die Umschlingung an dem Kühlrohr bedingte Maß hinaus zu verändern, wird gemäß einer besonders vorteilhaften Weiterbildung der Erfindung vorgeschlagen, dem Fadenheber im Fadenlauf eine Fadenbremse zuzuordnen. Durch die Fadenbremse wird an dem Faden im Bereich der Teillänge ohne Kontakt eine zusätzliche Reibung erzeugt.In order to change the thread tension within the false twist zone beyond the extent caused by the looping on the cooling tube, it is proposed according to a particularly advantageous development of the invention to assign a thread brake to the thread lifter in the thread run. By the yarn brake an additional friction is generated on the thread in the region of the partial length without contact.

Dabei läßt sich die Fadenbremse vorteilhaft durch einen Bremsstift ausbilden, welcher den Fadenheber im Fadenlauf derart vorgeordnet ist, so daß der Faden vor Einlauf in den Fadenheber den Bremsstift zumindest teilumschlingt.In this case, the yarn brake can advantageously be formed by a brake pin, which is arranged upstream of the thread lifter in the yarn path, so that the thread at least partially surrounds the brake pin before entering the thread lifter.

Durch eine Verstellung des Bremsstiftes an dem Halter oder dem Ringsegment des Fadenhebers können sowohl Zustände mit und ohne Fadenbremse realisiert werden. Zudem ist der Grad der Fadenumschlingung an dem Bremsstift veränderbar.By adjusting the brake pin on the holder or the ring segment of the thread lifter both states can be realized with and without thread brake. In addition, the degree of Fadenumschlingung on the brake pin is changeable.

Zur Erhöhung der Flexibilität hinsichtlich Fadenführung und Steigung der wendelförmigen Kühlstrecke können der Einlauffadenführer und der Auslauffadenführer oder nur einer der Fadenführer verstellbar ausgebildet sein.To increase the flexibility with regard to thread guidance and pitch of the helical cooling section, the inlet thread guide and the outlet thread guide or only one of the thread guides can be made adjustable.

Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung ist unter Hinweis auf die beigefügten Zeichnungen nachfolgend näher beschrieben.An embodiment of the device according to the invention is described in more detail below with reference to the accompanying drawings.

In Fig. 1 ist schematisch der Aufbau einer Bearbeitungsstelle einer erfindungsgemäßen Texturiermaschine dargestellt. Die Texturiermaschine besitzt eine Vielzahl von Bearbeitungsstellen, wobei die Prozeßaggregate der Bearbeitungsstellen in einem oder in mehreren Maschinengestellen gehalten sind. Um einen Faden 1 zu texturieren, enthält eine Bearbeitungsstelle zumindest ein erstes Lieferwerk 5, eine Heizeinrichtung 6, eine Kühleinrichtung 7, ein Falschdrallaggregat 15, ein zweites Lieferwerk 14 und eine Aufwickeleinrichtung 16, wobei die Prozeßaggregate zu einem Fadenlauf hintereinander angeordnet sind. Dabei wird ein Faden 1 von einer Vorlagenspule 2 durch das erste Lieferwerk 5 abgezogen. Die Vorlagespule 2 ist auf einem Dorn 3 eines Gatters (hier nicht dargestellt) aufgesteckt. Das erste Lieferwerk 5 führt den Faden 1 in die sogenannte Falschdrallzone, die sich bis zum Falschdrallaggregat 15 erstreckt. Durch das Falschdrallaggregat 15 wird in dem Faden 1 ein Falschdrall erzeugt, der innerhalb der Falschdrallzone in dem Faden zurückläuft. Hierzu kann das Falschdrallaggregat 15 beispielsweise mehrere sich überlappende Friktionsscheiben aufweisen, die an dem Faden ein Falschdrall erzeugen. Innerhalb der Falschdrallzone läuft der Falschdrall in dem Faden zurück und wird dabei in der Heizeinrichtung 6 erwärmt und anschließend in der Kühleinrichtung 7 fixiert. Durch das zweite Lieferwerk 14 wird der Faden vom Falschdrallaggregat 15 abgezogen und der Aufwickeleinrichtung 16 zugeführt. In der Aufwickeleinrichtung 16 wird der Faden 1 zu einer Spule 17 gewickelt.In Fig. 1, the structure of a processing point of a texturing machine according to the invention is shown schematically. The texturing machine has a plurality of processing stations, wherein the processing units of the processing stations are held in one or more machine racks. To texturize a thread 1, a processing station includes at least a first delivery mechanism 5, a heater 6, a cooling device 7, a false twist unit 15, a second delivery mechanism 14 and a take-up device 16, wherein the processing units are arranged to form a threadline one behind the other. In this case, a thread 1 is withdrawn from a document spool 2 by the first delivery mechanism 5. The supply spool 2 is mounted on a mandrel 3 of a gate (not shown here). The first delivery mechanism 5 guides the thread 1 into the so-called false twist zone, which extends as far as the false twist unit 15. By the false twist unit 15, a false twist is generated in the thread 1, which runs back within the false twist zone in the thread. For this purpose, the false twist unit 15, for example, have a plurality of overlapping friction discs, which generate a false twist on the thread. Within the false twist zone, the false twist runs back in the thread and is thereby heated in the heating device 6 and then fixed in the cooling device 7. By the second delivery mechanism 14, the thread is subtracted from the false twist unit 15 and fed to the take-up device 16. In the winding device 16, the thread 1 is wound into a coil 17.

Um den Faden 1 innerhalb der Falschdrallzone abzulcühlen, besteht die Kühleinrichtung 7 aus einem Kühlrohr 8, das über eine Leitung 10 mit einer Kühlmittelquelle 9 verbunden ist. Dem Kühlrohr 8 ist an einem Ende ein Einlauffadenführer 18, welcher den Faden 1 zu dem Kühlrohr 8 hinführt und am gegenüberliegenden Ende ein Auslauffadenführer 19 zugeordnet. Das Ende des Kühlrohres 8 im Bereich des Einlauffadenführers 18 wird hier als Auflaufende 20 und das gegenüberliegende Ende des Kühlrohres 8 als Ablaufende 21 bezeichnet. Dabei erfolgt die Zuführung des Kühlmittels über das Auflaufende 20, welches durch die Leitung 10 mit der Kühlquelle 9 verbunden ist. Durch das Kühlmittel wird die Wandung des Kühlrohres 8 gekühlt.In order to cool the thread 1 within the false twist zone, the cooling device 7 consists of a cooling tube 8, which is connected via a line 10 to a coolant source 9. The cooling tube 8 is an inlet yarn guide 18 at one end, which leads the yarn 1 to the cooling tube 8 and assigned at the opposite end a discharge yarn guide 19. The end of the cooling tube 8 in the region of the inlet thread guide 18 is referred to here as a run-up end 20 and the opposite end of the cooling tube 8 as a drain end 21. In this case, the supply of the coolant via the end of run 20, which is connected by the line 10 to the cooling source 9. By the coolant, the wall of the cooling tube 8 is cooled.

Im Bereich zwischen dem Einlauffadenführer 18 und dem Auslauffadenführer 19 ist am Umfang des Kühlrohres 8 ein Fadenheber 11 angeordnet. Der Fadenheber 11 wird durch ein Ringsegment 12 gebildet, daß am Umfang des Kühlrohres 8 angebracht ist. Das Ringsegment 12 besitzt eine äußere Führungskante 10, die sich mit Abstand zu der Oberfläche des Kühlrohres 8 im wesentlichen in radialer Richtung erstreckt.In the area between the inlet yarn guide 18 and the outlet yarn guide 19, a thread lifter 11 is arranged on the circumference of the cooling tube 8. The thread lifter 11 is formed by a ring segment 12 that is mounted on the circumference of the cooling tube 8. The ring segment 12 has an outer leading edge 10 which extends at a distance from the surface of the cooling tube 8 substantially in the radial direction.

In Fig. 2 ist schematisch eine Ansicht der Kühleinrichtung der Texturiermaschine aus Fig. 1 dargestellt. Der Einlauffadenführer 18 und der Auslauffadenführer 19 sind schwenkbar ausgebildet, so daß der Grad der Umschlingung und damit die wendelförmige Kühlstrecke am Umfang des Kühlrohres 8 einstellbar sind. Im Bereich des Fadenhebers 11 wird der Faden 1 über die Führungskante 13 des Ringsegmentes 12 geführt. Dadurch wird der Kontakt zwischen dem Faden 1 und der Oberfläche des Kühlrohres 8 über eine Teillänge unterbrochen. Die Größe der Teillänge ist dabei von dem Abstand zwischen der Führungskante 13 und der Oberfläche des Kühlrohres 8 sowie von dem Grand der Steigung der wendelförmigen Kühlstrecke am Umfang des Kühlrohres 8 abhängig. Dabei läßt sich das Ringsegment 12 sowohl in axialer Richtung als auch in radialer Richtung am Umfang des Kühlrohres 8 verstellen.FIG. 2 schematically shows a view of the cooling device of the texturing machine from FIG. 1. The inlet yarn guide 18 and the outlet yarn guide 19 are pivotally formed so that the degree of wrap and thus the helical cooling path on the circumference of the cooling tube 8 are adjustable. In the region of the thread lifter 11, the thread 1 is guided over the leading edge 13 of the ring segment 12. As a result, the contact between the thread 1 and the surface of the cooling tube 8 is interrupted over a partial length. The size of the part length is dependent on the distance between the leading edge 13 and the surface of the cooling tube 8 and the Grand of the slope of the helical cooling section on the circumference of the cooling tube 8. In this case, the ring segment 12 can be adjusted both in the axial direction and in the radial direction on the circumference of the cooling tube 8.

Bei unveränderter Steigung der wendelförmigen Kühlstrecke läßt sich der Abstand zwischen der Führungskante 13 und der Oberfläche des Kühlrohres 8 durch die Verstellung des Ringsegmentes 12 verändern. Hierzu besitzt das Ringsegment 12 eine elliptische oder stufenförmige Form, wie in Fig. 3 dargestellt. Durch Verstellung des Ringsegmentes 12 an dem Kühlrohr 8 kann somit die relative Lage des Fadens 1 an der Führungskante 3 und damit der Abstand zur Oberfläche des Kühlrohres 8 verändert werden. Die Formgebung des Ringsegmentes 12 ist beliebig, so daß jeder Fadenabstand realisierbar ist. So könnte beispielsweise das Ringsegment 12 einen Bereich aufweisen, in welchem der Faden einen Kontakt zum Kühlrohr 8 beibehält.With unchanged pitch of the helical cooling section, the distance between the leading edge 13 and the surface of the cooling tube 8 by the adjustment of the ring segment 12 can be changed. For this purpose, the ring segment 12 has an elliptical or stepped shape, as shown in Fig. 3. By adjusting the ring segment 12 on the cooling tube 8 thus the relative position of the thread 1 at the leading edge 3 and thus the distance to the surface of the cooling tube 8 can be changed. The shape of the ring segment 12 is arbitrary, so that each thread spacing can be realized. For example, the ring segment 12 could have a region in which the thread maintains contact with the cooling tube 8.

Das Ringsegment 12 ist durch ein Fixiermittel 29 an dem Umfang des Kühlrohres 8 fixiert. Durch Lösen des Fixiermittels 29 läßt sich das Ringsegment 12 in jede beliebige Position am Umfang des Kühlrohres 8 bewegen.The ring segment 12 is fixed by a fixing means 29 on the circumference of the cooling tube 8. By loosening the fixing means 29, the ring segment 12 can be moved to any position on the circumference of the cooling tube 8.

In Fig. 4 ist ein weiteres Ausführungsbeispiel einer Kühlvorrichtung 7 dargestellt, wie sie beispielsweise in der in Fig. 1 gezeigten Texturiermaschine einsetzbar wäre. Hierbei ist dem Kühlrohr 8 zwischen dem Einlauffadenführer 18 und dem Ablauffadenführer 19 ein Fadenheber 11 zugeordnet. Der Fadenheber 11 wird durch einen Halter 22 und einem Fadenführer 23 gebildet. Der Halter 22 ist seitlich neben dem Kühlrohr angebracht. Der Fadenführer 23 ist als Stift ausgebildet, und ragt in die Fadenlaufebene des Kühlrohres 8 hinein. Dabei wird der Faden 1 innerhalb der Kühlstrecke im Bereich des Kühlrohres 8 über den Fadenführer 23 geführt, so daß in einem Teilbereich der Kühlstrecke der Faden 1 ohne Kontakt zur Oberfläche des Kühlrohres 8 ist.4, a further embodiment of a cooling device 7 is shown, as they would be used for example in the texturing machine shown in Fig. 1. Here, the cooling tube 8 is assigned a thread lifter 11 between the inlet yarn guide 18 and the drain guide 19. The thread lifter 11 is formed by a holder 22 and a yarn guide 23. The holder 22 is mounted laterally adjacent to the cooling tube. The yarn guide 23 is formed as a pin, and protrudes into the yarn running plane of the cooling tube 8. In this case, the thread 1 is guided within the cooling section in the region of the cooling tube 8 via the thread guide 23, so that in a partial region of the cooling section of the thread 1 without contact with the surface of the cooling tube 8.

In den Fig. 5 und 6 ist ein weiteres Ausführungsbeispiel einer Kühlvorrichtung 7 gezeigt, wie sie beispielsweise in der Texturiermaschine nach Fig. 1 einsetzbar wäre. Hierbei ist nur ein Ausschnitt des Kühlrohres 8 mit einem Fadenheber 11 dargestellt. Fig. 5 zeigt die Kühleinrichtung in einer Querschnittsansicht und Fig. 6 die Kühleinrichtung 7 in einer Seitenansicht. Die nachfolgende Beschreibung gilt für beide Figuren insoweit kein ausdrücklicher Bezug zu einer der Figuren gemacht ist.5 and 6, a further embodiment of a cooling device 7 is shown, as it would be used for example in the texturing machine of FIG. Here, only a section of the cooling tube 8 is shown with a thread lifter 11. FIG. 5 shows the cooling device in a cross-sectional view, and FIG. 6 shows the cooling device 7 in a side view. The following description applies to both figures insofar as no explicit reference is made to one of the figures.

Der Fadenheber 11 ist durch einen ringförmigen Halter 24 gebildet, der am Umfang des Kühlrohres 8 aufgesteckt ist. Der ringförmige Halter 24 besitzt eine außenliegende Nut 25, in welchem Nutgrund der Faden 1 geführt ist. Zwischen dem Nutgrund der Nut 25 und der Oberfläche des Kühlrohres 8 ist ein Abstand gebildet, so daß der Faden 1 in einem Teilbereich der wendelförmigen Kühlstrecke ohne Kontakt zu dem Kühlrohr 8 geführt ist.The thread lifter 11 is formed by an annular holder 24 which is attached to the circumference of the cooling tube 8. The annular holder 24 has an outer groove 25, in which groove bottom of the thread 1 is guided. Between the groove bottom of the groove 25 and the surface of the cooling tube 8, a distance is formed, so that the thread 1 is guided in a partial region of the helical cooling section without contact with the cooling tube 8.

Dem Fadenführer 11 ist im Fadenlauf eine Fadenbremse 26 vorgeordnet. Die Fadenbremse 26 wird hierbei durch einen Bremsstift 27 gebildet, der über einen Träger 28 verstellbar mit dem ringförmigen Halter 24 verbunden ist. Der Bremsstift 27 ist im Fadenlauf der Nut 25 vorgeordnet, wobei die Position des Bremsstiftes 27 relativ zu dem Nutgrund der Nut 25 veränderbar ist. Somit besteht die Möglichkeit, den Faden 1 innerhalb der Kühlstrecke am Umfang des Kühlrohres 8 mit oder ohne zusätzlicher Umschlingung an dem Bremsstift 22 zu führen. Die Umschlingung des Fadens 1 an dem Bremsstift 22 bewirkt eine zusätzliche Fadenreibung, die zu einem weiteren Abbau der Drallschwingungen in dem Faden 1 innerhalb der Kühlstrecke führt. Damit können insbesondere Fäden mit Feintitern bei geringer Gesamtumschlingung von <360° vorteilhaft texturieren. Selbst bei kleinen Umschlingungswinkeln innerhalb der Kühlstrecke an dem Kühlrohr 8 kann durch die dem Fadenheber 11 zugeordnete Fadenbremse 26 ein ausreichender Abbau der Drallschwingungen bis zum Einlauf in die Heizeinrichtung 6 realisiert werden.The yarn guide 11 is preceded by a yarn brake 26 in the yarn path. The yarn brake 26 is in this case formed by a brake pin 27, which has a Carrier 28 is adjustably connected to the annular holder 24. The brake pin 27 is disposed in the yarn path of the groove 25, wherein the position of the brake pin 27 relative to the groove bottom of the groove 25 is variable. Thus, it is possible to guide the thread 1 within the cooling section on the circumference of the cooling tube 8 with or without additional looping on the brake pin 22. The looping of the thread 1 on the brake pin 22 causes additional thread friction, which leads to a further reduction of the swirl vibrations in the thread 1 within the cooling section. In particular, yarns with fine titers can advantageously texturize with a low overall wrap of <360 °. Even with small angles of wrap within the cooling section on the cooling tube 8, a sufficient reduction of the swirl vibrations can be realized by the yarn brake 11 associated with the thread brake 26 to the inlet to the heater 6.
