Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Färbespule gemäß dem Oberbegriff des Anspruches 1.The invention relates to a method for producing a dyeing bobbin according to the preamble of claim 1.

Im Zusammenhang mit der Herstellung von Färbespulen ist seit langem das Problem bekannt, dass diese Spulen oft nicht gleichmäßig durchgefärbt werden.In connection with the production of dye packages has long been known the problem that these coils are often not uniformly colored.

Derartige Färbespulen weisen insbesondere im Bereich ihrer auf der Färbespulenhülse liegenden inneren Fadenlagen oft Farbunterschiede auf. Das heißt, die inneren Fadenlagen unterscheiden sich in ihrer Farbgebung oft mehr oder weniger deutlich von den übrigen Fadenlagen der Färbespulen.Such dyeing coils often have color differences, in particular in the region of their inner thread layers lying on the dyeing bobbin tube. That is, the inner thread layers differ in their color often more or less clearly from the other thread layers of the dyeing bobbins.

Da sich solche Farbunterschiede bei der weiteren Verarbeitung der Färbspulen höchst negativ auswirken, war es bislang üblich, Färbespulen vor der Weiterverarbeitung entweder umzuspulen und bei dieser Gelegenheit die fehlerhaft gefärbten Fadenlagen zu entfernen, oder sofort spezielle, sehr weiche Färbespulen zu wickeln.Since such color differences have the greatest negative impact on the further processing of the dyeing bobbins, it has hitherto been customary to either rewind dyeing bobbins before further processing and to remove the incorrectly colored thread layers on this occasion, or to immediately wind special, very soft dye bobbins.

Die EP 0 787 674 A2 beschreibt beispielsweise einen Kreuzspulautomaten, der so ausgestattet ist, dass eine vorbestimmte Menge der fehlerhaft gefärbten, inneren Fadenlagen pneumatisch abgesaugt werden kann.The EP 0 787 674 A2 describes, for example, a cheese winder that is equipped so that a predetermined amount of faulty colored inner thread layers can be pneumatically sucked.

Das bekannte Verfahren weist allerdings den gravierenden Nachteil auf, dass es nicht nur relativ energieaufwendig ist, sondern auch einen verhältnismäßig geringen Wirkungsgrad besitzt.However, the known method has the serious disadvantage that it is not only relatively energy-consuming, but also has a relatively low efficiency.

Ein solches relativ energieaufwendiges Umspulen kann vermieden werden, wenn eine Färbespule möglichst weich gewickelt wird, das heißt, wenn bei der Herstellung der Kreuzspule mit einem relativ großen Kreuzungswinkel gearbeitet wird, was bekanntlich zur Herstellung einer Kreuzspule niedriger Dichte führt.Such a relatively energy-intensive rewinding can be avoided if a dyeing coil is wound as soft as possible, that is, when in the manufacture of the cheese with a relative working large crossing angle, which is known to produce a cross-wound bobbin low density.

Eine solche weiche Kreuzspule verfügt allerdings, bezogen auf ihren Durchmesser, über relativ wenig Garnmasse, was wiederum dazu führt, dass der erforderliche Einsatz an Färbeflotte pro Kilogramm Garn recht hoch ist.However, such a soft cheese has, based on their diameter, relatively little yarn mass, which in turn means that the required use of dye liquor per kilogram of yarn is quite high.

Das heißt, die Herstellung solcher relativ weich gewickelter Färbespulen hat den Nachteil, dass die Färbekosten verhältnismäßig hoch sind.That is, the production of such relatively soft wound dye packages has the disadvantage that the coloring costs are relatively high.

Im Zusammenhang mit der Herstellung von Kreuzspulen ist es außerdem seit langem grundsätzlich bekannt, verschiedene Wicklungsarten einzusetzen.In connection with the production of cheeses, it has also long been known in principle to use different types of winding.

In der Textilindustrie unterscheidet man dabei insbesondere zwischen zwei Kategorien, der so genannten "Wilden Wicklung" und der so genannten "Präzisionswicklung".In the textile industry, a distinction is made in particular between two categories, the so-called "wild winding" and the so-called "precision winding".

Bei der "Wilden Wicklung" besteht ein festes Verhältnis zwischen der Umfangsgeschwindigkeit der Kreuzspule und der Geschwindigkeit der Fadenchangierung.In the "wild winding" there is a fixed relationship between the peripheral speed of the cheese and the speed of Fadenchangierung.

Hierdurch wird der Kreuzungswinkel des Fadens auf der Oberfläche der Kreuzspule konstant gehalten, während das Windungsverhältnis, das heißt, die Anzahl der Spulenumdrehungen pro Doppelhub, mit zunehmendem Kreuzspulendurchmesser kleiner wird.As a result, the crossing angle of the thread on the surface of the cross-wound bobbin is kept constant, while the turns ratio, that is, the number of bobbin revolutions per double stroke, becomes smaller as the cross-wound bobbin diameter increases.

Nachteilig bei dieser Wicklungsart ist allerdings, dass, wenn keine zusätzlichen Maßnahmen ergriffen werden, so genannte Bildwickelzonen auftreten, die das Ablaufverhalten und das Färbeverhalten derartiger Kreuzspulen höchst negativ beeinflussen.A disadvantage of this type of winding, however, is that, if no additional measures are taken, so-called Bildwickelzonen occur that negatively affect the flow behavior and the dyeing behavior of such cheeses.

Bei der "Präzisionswicklung" besteht ein konstantes Verhältnis zwischen der Spulendrehzahl und der Geschwindigkeit der Fadenchangierung und damit ein festes Windungsverhältnis während der gesamten Spulenreise.In the case of "precision winding", there is a constant relationship between the number of revolutions of the reel and the speed of threading and thus a fixed turn ratio during the entire coil travel.

Bei dieser Wicklungsart treten keine Bildwickelzonen auf, so dass derartig gewickelte Kreuzspulen ein sehr gutes Ablaufverhalten besitzen.In this type of winding, no image winding zones occur, so that such wound packages have very good drainage behavior.

Bedingt durch den während der Spulenreise immer kleiner werdenden Fadenkreuzungswinkel ist die Stabilität des Spulenkörpers und die Durchfärbbarkeit derartig gewickelter Kreuzspulen allerdings eingeschränkt.Due to the ever smaller during the coil travel crosshairs angle, the stability of the bobbin and the Durchfärbbarkeit such wound coils is, however, limited.

Um die Vorteile der beiden vorgenannten Wicklungsarten zu kombinieren und gleichzeitig deren Nachteile zu eliminieren, wurde die so genannte "Stufenpräzisionswicklung" entwickelt.In order to combine the advantages of the two aforementioned types of winding and at the same time to eliminate their disadvantages, the so-called "step precision winding" has been developed.

Bei der "Stufenpräzisionswicklung" wird die Kreuzspule fertigungstechnisch in mehrere, radial übereinander angeordnete Einzelspulen unterteilt, wobei jede Einzelspule in der Wicklungsart "Präzisionswicklung" erstellt wird.In the "step precision winding" the cross-wound bobbin production technology is divided into a plurality of radially superposed individual coils, each individual coil is created in the winding "precision winding".

Das heißt, auch bei diesen Einzelspulen nimmt der Kreuzungswinkel von einem Ausgangswert beginnend stetig ab. Am Übergang einer Einzelspule zur nächsten Einzelspule wird der Kreuzungswinkel des Fadens allerdings stets wieder auf den ursprünglichen Ausgangswert des Kreuzungswinkels zurückgeführt.That is, even with these individual coils, the crossing angle decreases steadily starting from an initial value. At the transition of a single coil to the next single coil, however, the crossing angle of the thread is always returned to the original starting value of the crossing angle.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zu entwickeln, das eine kostengünstige Herstellung von Färbespulen ermöglicht, wobei jedoch sichergestellt ist, dass die auf die erfindungsgemäße Weise erstellten Färbespulen beim nachfolgenden Färbeprozess gleichmäßig durchgefärbt werden.Based on the aforementioned prior art, the present invention seeks to develop a method that allows a cost-effective production of dye packages, but it is ensured that the dyeing bobbins created in the manner of the invention are uniformly colored during the subsequent dyeing process.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren gelöst, wie es im Anspruch 1 beschrieben ist.This object is achieved by a method as described in claim 1.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche.Advantageous embodiments of the method according to the invention are the subject of the dependent claims.

Das erfindungsgemäße Verfahren, bei dem zu Beginn der Spulenreise zunächst in der Wicklungsart Präzisionswicklung gewickelt und dabei mit einem sehr großen Kreuzungswinkel gestartet wird, hat insbesondere den Vorteil, dass die Färbespule im Bereich ihrer kritischen inneren Fadenlagen, das heißt, im Bereich der Fadenlagen, die die gelochte Färbspulenhülse umwickeln, eine Wicklung mit geringerer Dichte aufweist.The inventive method, in which at the beginning of the coil travel initially wound in the winding type precision winding and thereby started with a very large crossing angle, has the particular advantage that the dyeing coil in the region of their critical inner thread layers, that is, in the field of thread layers, the Wrap the perforated dye bobbin tube, having a lower density coil.

Eine solche weniger dichte Fadenwicklung ermöglicht es, dass sich die Färbeflotte auch im Bereich der inneren Fadenlagen gleichmäßig ausbreiten kann, was zu einem guten Färbeergebnis, das heißt, gleichmäßig durchgefärbten Färbespulen führt.Such a less dense thread winding makes it possible for the dyeing liquor to spread evenly in the region of the inner thread layers, which leads to a good dyeing result, that is to say evenly dyed dye packages.

Da bei Erreichen eines vorgebbaren, deutlich kleineren Kreuzungswinkels auf die Wicklungsart Stufenpräzisionswicklung umgeschaltet wird, ist außerdem sicherstellt, dass die Färbespule insgesamt einen vorteilhaften Spulenaufbau mit einer höheren, das Durchfärben noch gestattenden Spulendichte und damit eine hohe Materialmasse aufweist.Since, when a predeterminable, significantly smaller crossing angle is switched to the winding type step precision winding, it is also ensured that the dyeing coil has an advantageous overall coil construction with a higher, the dyeing still permitting coil density and thus a high mass of material.

Das heißt, die nach dem erfindungsgemäßen Verfahren hergestellten Färbespulen überzeugen sowohl hinsichtlich ihrer Färbekosten, als auch bezüglich ihrer Durchfärbeeigenschaften.That is, the dye packages produced by the process according to the invention convince both in terms of their coloring costs, as well as with respect to their Durchfärbeeigenschaften.

Vorteilhafterweise wird beim Start der Spulenreise, das heißt, beim Start der Präzisionswicklung mit einem Kreuzungswinkel gearbeitet, dessen Anfangswert bei > 40 Grad liegt.Advantageously, at the start of the coil travel, that is to say when the precision winding is started, a crossing angle is used whose initial value is> 40 degrees.

Durch einen so großen Kreuzungswinkel lassen sich Farbstörungen im Bereich der inneren Fadenlagen, wie sie bislang nahezu die Regel waren, auf relativ einfache Weise zuverlässig vermeiden. Bei Erreichen eines vorgebbaren, kleineren Kreuzungswinkels, dessen Wert vorzugsweise bei < 35 Grad liegt, wird von Präzisionswicklung auf Stufenpräzisionswicklung umgeschaltet.By such a large crossing angle can color disturbances in the area of the inner thread layers, as they were almost the rule so far, relatively reliably avoid. When a predefinable, smaller crossing angle, whose value is preferably <35 degrees, is switched from precision winding to step precision winding.

Ein solcher, auch als Startwinkel der Stufenpräzisionswicklung fungierender Kreuzungswinkel von < 35 Grad, der im Zuge des Wickelprozesses stetig weiter abnimmt, ermöglicht das Winkeln von Kreuzspulen mit einer relativ großen Materialmasse, wobei durch den Einsatz der Stufenpräzisionswicklung außerdem ein gutes Ablaufverhalten der Kreuzspule gewährleistet ist.Such, also acting as a starting angle of the step precision winding crossing angle of <35 degrees, which steadily decreases in the course of the winding process, allows the angle of cheeses with a relatively large mass of material, with the use of the step precision winding also a good flow behavior of the cheese is guaranteed.

Wie im Anspruch 2 beschrieben, ist in vorteilhafter Ausführungsform des Weiteren vorgesehen, dass während der Erstellung der Stufenpräzisionswicklung die Windungsverhältnisse so gewählt werden, dass der Fadenabstand des auf die Kreuzspule auflaufenden Fadens einen nahezu gleich bleibenden Wert aufweist. Auf diese Weise wird eine nahezu konstante Dichte des Garnkörpers erreicht, was sich beim nachfolgenden Färbeprozess vorteilhaft auswirkt.As described in claim 2, it is further provided in an advantageous embodiment that during the preparation of the step precision winding, the turns ratios are selected so that the thread pitch of the thread running onto the cross-wound bobbin has an almost constant value. In this way, a nearly constant density of the package is achieved, which has an advantageous effect in the subsequent dyeing process.

Das erfindungsgemäße Verfahren wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert.The inventive method will be explained in more detail with reference to an embodiment shown in the drawings.

In Figur 1 ist schematisch, in Seitenansicht, eine insgesamt mit der Bezugszahl 1 gekennzeichnete Kreuzspulen herstellende Textilmaschine, im Ausführungsbeispiel ein Kreuzspulautomat, dargestellt.In FIG. 1 is schematically, in side view, a generally designated by the reference numeral 1 cheesemaking fabricating textile machine, in the embodiment, a cheese winding machine, shown.

Derartige Kreuzspulautomaten besitzen üblicherweise zwischen ihren (nicht dargestellten) Endgestellen eine Vielzahl gleichartiger Arbeitsstellen 2, auf denen, wie bekannt und daher nicht näher erläutert, auf Ringspinnmaschinen gefertigte Spinnkopse 9 zu großvolumigen Kreuzspulen 11, im Ausführungsbeispiel zu Färbespulen, umgespult werden.Such spoolers usually have between their (not shown) Endgestellen a variety of similar jobs 2, where, as known and therefore not further explained, spinning rings made on ring spinning machines 9 to voluminous cheeses 11, in the embodiment to dyeing coils, rewound.

Die Kreuzspulen 11 werden nach ihrer Fertigstellung, zum Beispiel durch Verschwenken des Spulenrahmens 18 um die Schwenkachse 19, auf eine maschinenlange Kreuzspulen-Transporteinrichtung 21 überführt und zu einer maschinenendseitig angeordneten (nicht dargestellten) Spulenverladestation oder dergleichen transportiert, von wo aus sie zu einer Färbestation überstellt werden.The cheeses 11 are, after their completion, for example, by pivoting the creel 18 about the pivot axis 19, transferred to a machine-length cross-wound conveyor 21 and transported to a machine end side (not shown) Spulenverladestation or the like, from where they transferred to a dyeing station become.

Derartige Kreuzspulautomaten 1 weisen oft eine Logistikeinrichtung in Form eines Spulen- und Hülsentransportsystems 3 auf. Innerhalb dieser Logistikeinrichtung laufen, auf Transporttellern 8 in vertikaler Ausrichtung festgelegt, Spinnkopse 9 beziehungsweise Leerhülsen 34 um.Such automatic packages 1 often have a logistics device in the form of a package and tube transport system 3. Run within this logistics facility, set on transport plates 8 in a vertical orientation, spinning cops 9 and empty tubes 34 to.

Von diesem bekannten Spulen- und Hülsentransportsystem 3 sind in Fig.1 lediglich die Kopszuführstrecke 4, die reversierend antreibbare Speicherstrecke 5, eine der zu den Spulstellen 2 führenden Quertransportstrecken 6 sowie die Hülsenrückführstrecke 7 dargestellt. Die angelieferten Spinnkopse 9 werden dabei in einer der Abspulstellungen 10, die sich jeweils im Bereich der Quertransportstrecken 6 befinden, umgespult.From this known coil and sleeve transport system 3 are in Fig.1 only the Kopszuführstrecke 4, the reversibly driven storage section 5, one of the leading to the winding units 2 transverse transport sections 6 and the sleeve return path 7 shown. The delivered spinning cops 9 are rewound in one of the Abspulstellungen 10, which are each located in the region of the transverse transport sections 6.

Wie bekannt, verfügen die einzelnen Arbeitsstellen 2 zu diesem Zweck über verschiedene Einrichtungen, die ein ordnungsgemäßes Umspulen ermöglichen.As is known, the individual workstations 2 for this purpose have various facilities that allow proper rewinding.

In Figur 1 ist der vom Spinnkops 9 zur Kreuzspule 11 laufende Faden mit der Bezugszahl 30 gekennzeichnet.In FIG. 1 the thread running from the spinning cop 9 to the cheese 11 is identified by the reference numeral 30.

Der Faden 30 durchläuft auf seinem Weg zur Kreuzspule 11 beispielsweise einen Unterfadensensor 22, eine Fadenspanneinrichtung 14, einen Fadenreiniger 15 mit einer Fadenschneideinrichtung 17 sowie einen Fadenzugkraftsensor 20.The thread 30 passes on its way to the cheese 11, for example, a lower thread sensor 22, a thread tensioning device 14, a thread cleaner 15 with a thread cutting device 17 and a yarn tension sensor 20th

Solche Arbeitsstellen 2 verfügen außerdem jeweils über eine Spleißeinrichtung 13, eine Saugdüse 12 sowie ein Greiferrohr 27. Außerdem weisen derartige Arbeitsstellen 2 eine insgesamt mit der Bezugszahl 24 gekennzeichnete Spulvorrichtung mit einem Spulenrahmen 18 auf, der um eine Schwenkachse 19 beweglich gelagert ist.Such work stations 2 also each have a splicing device 13, a suction nozzle 12 and a gripper tube 27. In addition, such jobs 2 have a generally designated by the reference numeral 24 winding device with a coil frame 18 which is movably mounted about a pivot axis 19.

Der Spulenrahmen 18 kann zur Fertigung konischer Kreuzspulen außerdem um eine (schematisch dargestellte) Schwenkachse 25 gedreht werden.The coil frame 18 can also be rotated about a (schematically shown) pivot axis 25 for the production of conical cheeses.

Zur Changierung des Fadens 30 während des Spulprozesses ist des Weiteren eine Fadenchangiereinrichtung 28 vorgesehen.For traversing the thread 30 during the winding process, a thread switching device 28 is furthermore provided.

Eine solche in Fig. 1 nur angedeutete und beispielsweise in der DE 199 60 024 A1 relativ ausführlich beschriebene Fadenchangiereinrichtung 28 besteht im Wesentlichen aus einem fingerartig ausgebildeten Fadenführer 29, der, durch einen elektromechanischen Antrieb 31 beaufschlagbar, den Faden 30 zwischen den beiden Stirnflächen der rotierenden Kreuzspule 11 traversiert. Der Faden 30 gleitet während seiner kreuzweisen Verlegung durch den Fadenführer 29 auf einem Führungslineal 32.Such in Fig. 1 only hinted and for example in the DE 199 60 024 A1 relatively extensively described Fadenchangiereinrichtung 28 essentially consists of a finger-like thread guide 29, which, acted upon by an electromechanical drive 31, the thread 30 traversed between the two end faces of the rotating cheese 11. The thread 30 slides during its crosswise laying by the yarn guide 29 on a guide ruler 32nd

Während des Spulprozesses liegt die über ihre Hülse 23 zwischen Hülsenaufnahmetellern des Spulenrahmens 18 gehaltene Kreuzspule 11 auf einer Walze 26.During the winding process, the cross-wound bobbin 11, which is held over its sleeve 23 between sleeve receiving plates of the creel 18, rests on a roller 26.

Die Walze 26 ist dabei entweder als einzelmotorisch angetriebene Spulenantriebswalze ausgebildet, die die Kreuzspule 11 über Reibschluss mitnimmt oder als antriebslose Stützwalze.The roller 26 is formed either as a single-motor driven reel drive roller which carries the cross-wound bobbin 11 via frictional engagement or as a drive-less support roller.

Im zweiten Fall wird die Kreuzspule 11 durch einen (nicht dargestellten) zum Beispiel in den Spulenrahmen 18 integrierten, drehzahlregelbaren Elektromotor angetrieben und nimmt dann die Stützwalze über Reibschluss mit.In the second case, the cheese 11 is driven by a (not shown), for example, in the creel 18 integrated, speed-adjustable electric motor and then takes the support roller with frictional engagement.

Die Figuren 2, 3 und 4 zeigen eine in einem nachfolgenden Färbeprozess fertigzustellende, als Kreuzspule gewickelte Färbespule 11 zu verschiedenen Zeitpunkten ihrer Spulenreise. Eine solche Färbespule 11 erhält jeweils einen inneren, in der Wicklungsart "Präzisionswicklung" gewickelten Wicklungsbereich, der, wie in Fig.2 angedeutet, zunächst einen relativ großen Kreuzungswinkel α aufweist sowie daran anschließend, mehrere, in der Wicklungsart "Stufenpräzisionswicklung" gespulten Wicklungsbereich.The FIGS. 2, 3 and 4 show a to be finished in a subsequent dyeing process, wound as a cross-wound dyeing coil 11 at different times of their trip coil. Such a dyeing coil 11 receives in each case an inner winding area wound in the winding type "precision winding", which, as in FIG Fig.2 indicated, first having a relatively large crossing angle α and subsequently, several, wound in the winding type "step precision winding" winding area.

In Fig.2 ist die Situation einer nach dem erfindungsgemäßen Wicklungsverfahren erstellten Färbespule 11 zu Beginn ihrer Spulenreise gezeigt.In Fig.2 the situation of a dyeing coil 11 produced according to the winding method according to the invention is shown at the beginning of its coil travel.

Wie dargestellt, wird der Faden 30 zu diesem Zeitpunkt unter einem relativ großen Kreuzungswinkel α auf die Hülse 23 aufgewickelt, wobei, wie vorstehend bereits angedeutet, das Aufspulen in der Wicklungsart "Präzisionswicklung" erfolgt.As shown, the thread 30 is wound at this time at a relatively large crossing angle α on the sleeve 23, wherein, as already indicated above, the winding in the winding type "precision winding" takes place.

Der Kreuzungswinkel α, der zu Beginn der Spulenreise vorzugweise etwa 42 Grad beträgt, verringert sich, wie bei Präzisionswicklung üblich, im Laufe der Spulenreise stetig und erreicht schließlich den in Fig.3 dargestellten Wert α1 von etwa 32°.The crossing angle α, which is preferably about 42 degrees at the beginning of the coil travel, decreases steadily, as usual in precision winding, in the course of the coil travel and finally reaches the in Figure 3 represented value α 1 of about 32 °.

Bei Erreichen dieses Kreuzungswinkelwertes wird die Spulvorrichtung 24 auf die Wicklungsart "Stufenpräzisionswicklung" umgeschaltet.Upon reaching this crossing angle value, the winding device 24 is switched to the winding type "step precision winding".

Das heißt, im vorliegenden Fall stellt der bereits im Vorfeld als Endkreuzungswinkel der Präzisionswicklung vorgegebene Winkel α1 = 32° auch den Eingangskreuzungswinkel für den nachfolgenden Stufenpräzisionswicklungsbereich dar.That is to say, in the present case, the angle α 1 = 32 ° predetermined in advance as the final intersection angle of the precision winding also represents the input intersection angle for the subsequent step precision winding area.

Auch dieser Eingangskreuzungswinkel α1 wird anschließend im Laufe der Spulereise stetig verkleinert und erreicht zum Ende jedes Stufenpräzisionswicklungsbereiches, je nach Einstellung, einen Wert zwischen 28 und 30 Grad, wie dies im Fig.4 anhand des Endkreuzungswinkel α2 dargestellt ist.This input intersection angle α 1 is then continuously reduced in the course of the winding travel and reaches the end of each stage precision winding region, depending on the setting, a value between 28 and 30 degrees, as in Figure 4 is represented by the final intersection angle α 2 .

Das vorstehend beschriebene Wickeln eines Stufenpräzisionswicklungsbereiches wird solange wiederholt, bis die Färbespule 11 ihren vorgegebenen Enddurchmesser erreicht hat.The above-described winding of a step precision winding region is repeated until the dyeing bobbin 11 has reached its predetermined final diameter.

Wie vorstehend bereits beschrieben, weist das erfindungsgemäße Verfahren verschiedene Vorteile auf.As already described above, the method according to the invention has various advantages.

Mit dem erfindungsgemäßen Verfahren können beispielsweise nicht nur relativ problemlos Färbespulen hergestellt werden, die aufgrund ihrer relativ offenen Fadenwicklungen im Kernbereich gut durchzufärben sind, sondern solche Färbespulen weisen aufgrund ihrer zahlreichen Stufenpräzisionswicklungsbereiche auch eine hohe Materialmasse auf, mit der Folge, dass die Färbekosten solcher Färbespulen recht günstig sind.With the method according to the invention, for example, dyeing bobbins which are easy to dye through because of their relatively open thread windings can be produced, but because of their numerous step precision winding areas, such dye bobbins also have a high mass of material, with the result that the dyeing costs of such dye bobbins are quite good are favorable.

Das erfindungsgemäße Verfahren ist allerdings nicht auf das in den Zeichnungen beschriebene Ausführungsbeispiel, insbesondere nicht auf das Umspulen von Spinnkopsen mittels eines Kreuzspulautomaten, beschränkt.However, the method according to the invention is not limited to the exemplary embodiment described in the drawings, in particular not to the rewinding of spinning cops by means of an automatic package winder.

Auch beim Wickeln von Kreuzspulen auf Offenend-Spinnmaschinen kann der Einsatz des erfindungsgemäßen Verfahrens vorteilhaft sein, wenn diese Kreuzspulen später zu Färbespulen gefärbt werden sollen.Even when winding cheeses on open-end spinning machines, the use of the method according to the invention may be advantageous if these cheeses are to be dyed later to dye packages.
