Description
Wickelhülsemandrel
Die Erfindung betrifft eine Wickelhülse aus Kunststoff mit einem rotationssymmetrischen Körper, aufweisend einen radial kompressiblen Mantel für Wickelgut mit einem ersten Endabschnitt und einem diesem gegenüberliegenden zweiten Endabschnitt.The invention relates to a winding tube made of plastic with a rotationally symmetrical body, comprising a radially compressible shell for winding material having a first end portion and a second end portion opposite thereto.
Eine derartige Wickelhülse ist beispielsweise aus der US 5 584 439 A bekannt. Die radiale Kompressibilität wird hier dadurch erreicht, dass zwei sich kreuzende wendeiförmig verlaufende Reihen von Langlöcher um den Mantel der Wickelhülse angeordnet sind. Die größte Ausdehnung eines jeden Langlochs ist dabei abwechselnd in Richtung des Wendelverlaufs oder quer dazu ausgerichtet.Such a winding tube is known, for example, from US Pat. No. 5,584,439. The radial compressibility is achieved here in that two intersecting helical rows of slots are arranged around the jacket of the winding tube. The largest extent of each slot is alternately aligned in the direction of the helical course or across it.
Vor dem Färbeprozess wird ein axialer Druck auf die genannte Wickelhülse und das darauf aufgewickelte Wickelgut ausgeübt, indem mehrere bewickelte und mittels ihrer Endabschnitte ineinander gesteckte Wickelhülsen an den beiden zuäußerst liegenden Endabschnitten zusammengedrückt werden. Durch das Zusammendrücken reduziert sich der Mantel jeder Wickelhülse in seiner axialen Ausrichtung, d.h. seiner Länge, wodurch sich für das Wickelgut eine gleichmäßigere Dichtigkeit, insbesondere im Bereich der Kontaktstellen benachbarter Hülsen, ergibt.Before the dyeing process, an axial pressure is exerted on said winding tube and the winding material wound thereon by compressing a plurality of wound and inserted into one another by means of their end portions of the winding tubes at the two outermost lying end portions. Compression reduces the sheath of each mandrel in its axial orientation, i. its length, resulting in a uniform density for the winding material, in particular in the region of the contact points of adjacent sleeves results.
Die Wickelhülse kompensiert außerdem durch radiale Kompression des Mantels die während des Färbeprozesses auftretende Schrumpfung des Wickelgutes und die damit verbundene unterschiedliche Zugspannung der verschiedenen Lagen/Bereiche des Wickelgutes. Durch die Kompensation werden die Unterschiede der Färbeintensität für das auf der Wickelhülse aufgespulte Wickelgut sowie Schäden an dem Wickelgut, die durch Druckkräfte verursacht sind, reduziert.The winding tube compensates also by radial compression of the shell occurring during the dyeing process shrinkage of the winding material and the associated different tension of the various layers / areas of the winding material. The compensation reduces the differences in the dyeing intensity for the winding material wound on the winding tube as well as damage to the winding material caused by compressive forces.
Allerdings ist bei den beschriebenen Wickelhülsen zu beobachten, dass die Verformung des zuvor rotationssymmetrischen Körpers der Wickelhülse die Ausbildung eines konkaven Körpers nach Art eines Diabolos evoziert, da die beiden Endabschnitte jeder Wickelhülse starr sind. Insbesondere bei Verwendung von Garnen mit großem Schrumpfvolumen als Wickelgut wird durch die starren Endabschnitte eine erhöhte Garndichte in diesem Bereich bewirkt. Außerdem wird das Ablaufverhalten durch die unregelmäßige Form der verformten Hülse negativ beeinflusst und die Fadenbruchgefahr erhöht.However, it can be observed in the winding cores described that the deformation of the previously rotationally symmetrical body of the winding tube evokes the formation of a concave body in the manner of a diabolos, since the two end portions of each winding tube are rigid. In particular when using yarns with a large shrinkage volume as the winding material, an increased yarn density in this area is brought about by the rigid end sections. In addition, the drainage behavior is adversely affected by the irregular shape of the deformed sleeve and increases the risk of yarn breakage.
Aufgabetask
Der Erfindung liegt somit die Aufgabe zugrunde, eine Wickelhülse zu schaffen, die es gestattet, die Dichtigkeit des aufgespulten Wickelgutes noch weiter zu vergleichmäßigen, um ein gleichmäßigeres Färbeergebnis zu erhalten und die es gestattet, bei Schrumpf- und/oder Bauschgarnen nach der Färbung/Trocknung einen annähernd rotationssymmetrischen Wickelkörper zu erhalten, der gleichmäßige Wickeldichten über die gesamte Bespulungslänge sowie ein gutes Ablaufverhalten ermöglicht, und die zur Verbesserung der Färbequalität und Verringerung der Fadenbruchzahlen, insbesondere bei höheren Abzugsgeschwindigkeiten, beiträgt.The invention is therefore an object of the invention to provide a winding tube, which allows the density of the wound-up winding material even further to equalize to obtain a more uniform dyeing result and which allows for shrinkage and / or Bauschgarnen after dyeing / drying to obtain an approximately rotationally symmetrical winding body, which allows uniform winding densities over the entire Bespulungslänge and a good flow behavior, and which contributes to improving the dyeing quality and reducing the number of yarn breaks, especially at higher take-off speeds.
Lösungsolution
Ausgehend von den bekannten Wickelhülsen wird nach der Erfindung vorgeschlagen, dass der jeweilige Umfang der Endabschnitte mittels mechanischem Druck, der mittel- oder unmittelbar durch das Wickelgut ausgeübt wird, reduzierbar ist.Starting from the known cores is proposed according to the invention that the respective circumference of the end portions by means of mechanical pressure, which is medium or directly exerted by the winding material, can be reduced.
Die Erfindung geht mit der radialen Reduzierbarkeit der Endabschnitte, d.h. auch der Reduzierung des Durchmessers in diesen Abschnitten, gegenüber dem Stand der Technik einen völlig neuen Weg, da es bisher bei der Konstruktion von Wickelhülsen üblich war, den Endabschnitt besonders massiv und starr im Verhältnis zum Mantel vorzusehen, etwa um die durch die Endlage der Endabschnitte bedingte besondere Beanspruchung auszugleichen, aber auch, um die Formsteifigkeit der Wickelhülse bei während des Wickelprozesses auftretenden hohen Drehzahlen zu erhalten. Es hat sich jedoch überraschend gezeigt, dass der obere und untere Spulteller den zwischen ihnen eingespannten zusammengesteckten neuartigen Wickelhülsen, auch bei Erreichen hoher Spuldrehzahlen, eine ausreichende, d.h. allen Anforderungen genügende, Stabilität und Laufruhe vermitteln.The invention is concerned with the radial reducibility of the end sections, i. also the reduction of the diameter in these sections, compared to the prior art, a completely new way, since it was usual in the construction of cores usual to provide the end portion particularly solid and rigid in relation to the jacket, such as by the end position of the end portions To compensate for conditional special stress, but also to obtain the stiffness of the winding tube at high speeds occurring during the winding process. However, it has surprisingly been found that the upper and lower Spulteller the clamped between them mated new winding tubes, even when reaching high Spuldrehzahlen, a sufficient, i. provide all requirements, stability and smoothness.
Der Radialdruck, der von dem unter Temperatureinfluss schrumpfenden Wickelgut ausgeübt wird, führt erfindungsgemäß zu einer Reduktion des jeweiligen Umfangs der betroffenen radial nachgiebigen Endabschnitte. Dadurch kann die Ausbildung einer konkaven Form mit den bekannten Nachteilen wirksam verhindert werden. Erwünscht ist insbesondere, dass die Endabschnitte auch im radial komprimierten Zustand rotationssymmetrisch zu der Mittelachse der Wickelhülse sind.The radial pressure which is exerted by the winding material shrinking under the influence of temperature leads according to the invention to a reduction of the respective circumference of the affected radially compliant end sections. This can make the training of a concave Form can be effectively prevented with the known disadvantages. It is particularly desirable that the end sections are rotationally symmetrical to the central axis of the winding tube even in the radially compressed state.
In einer Weiterbildung der Erfindung ist es vorgesehen, dass ein Endabschnitt eine Mehrzahl von in Umfangsrichtung voneinander beabstandeten Ringsegmenten aufweist, die mit ihren Stirnflächen vorzugsweise äquidistant zueinander angeordnet sind.In one development of the invention, it is provided that one end section has a plurality of circumferentially spaced-apart ring segments, which are preferably arranged with their end faces equidistantly from each other.
Die Ringsegmente sind durch die dem Kunststoffmaterial, etwa PE oder PP, innewohnende Elastizität zu der Rotationsachse der Wickelhülse hin verschiebbar und bilden mit ihrer Außenfläche zumindest für den ersten Endabschnitt, eine wirksame Ablagefläche für das Wickelgut.The ring segments are displaceable by the plastic material, such as PE or PP, inherent elasticity to the axis of rotation of the winding tube through and form with its outer surface, at least for the first end portion, an effective support surface for the winding material.
Eine ausreichende Stabilität wird ferner dadurch erreicht, dass die Ringsegmente durch Verbindungselemente, die sich im Bereich der Stirnflächen an die Ringsegmente anschließen, verbunden sind. Die Ringsegmente bilden zusammen mit den zwischengelagerten flexiblen Verbindungselementen einen geschlossenen und äußerst stabilen Endabschnitt.A sufficient stability is further achieved by the fact that the ring segments are connected by connecting elements which adjoin the ring segments in the region of the end faces. The ring segments together with the intermediate flexible connecting elements form a closed and extremely stable end section.
In einer Fortbildung der Erfindung ist vorgesehen, dass sich gegenüberliegende Stirnflächen benachbarter Ringsegmente miteinander in Kontakt bringbar sind, da die Stirnflächen auf diese Weise als Anschlagflächen fungieren und die Umfangsreduktion des entsprechenden Endabschnittes auf ein Maß begrenzen, bei dem sichergestellt ist, dass keinerlei Überdehnung der Ringsegmente stattfinden kann.In a further development of the invention it is provided that opposite end faces of adjacent ring segments can be brought into contact with each other, since the end faces act as stop surfaces in this way and limit the reduction in size of the corresponding end portion to a level which ensures that no overstretching of the ring segments can take place.
Wird in einer weiteren Fortbildung die Erfindung dadurch verbessert, dass der Kontakt formschlüssig ist, so wird ein „aneinander Abrutschen" der Stirnflächen wirksam vermieden. Der Formschluss kann etwa dadurch hergestellt werden, dass eine erste Stirnfläche eines Ringsegments als spitz zulaufender Grat ausgebildet ist und eine weitere Stirnfläche eines benachbarten Ringsegmentes durch eine dem Grat entsprechende Aussparung seiner Stirnfläche an die erste Stirnfläche angepasst ist.If, in a further development, the invention is improved in that the contact is form-fitting, then the end faces are effectively prevented from "slipping off." The positive connection can be produced, for example, by forming a first end face of a ring segment as a pointed ridge and one another end face of an adjacent ring segment is adapted by a ridge corresponding recess of its end face to the first end face.
Eine vorteilhaft Ausgestaltung der Erfindung sieht zudem vor, dass die Verbindungselemente entweder in einer Ebene transversal oder tangential zu der Mittelachse des Körpers gebogen und weiter biegbar sind, um eine definierte Biegebewegung, vorzugsweise zur Rotationssymmetrieachse der Wickelhülse hin, zu erreichen. Bevorzugt ist jedes Verbin- dungselement als dünner Film, d.h. als Filmscharnier, ausgebildet, so dass nur geringe Kräfte zur Biegung des jeweiligen Verbindungselementes vonnöten sind und dennoch genügend Halt und Stabilität für die mit ihnen verbundenen Ringsegmente gegen die Zentrifugalkraft bei Be- und Abwicklung der Wickelhülse gegeben ist.An advantageous embodiment of the invention also provides that the connecting elements are bent either transversely or tangentially to the central axis of the body in a plane and are further bendable in order to achieve a defined bending movement, preferably towards the rotational axis of symmetry of the winding tube. Preferably, each connection training element as a thin film, ie as a film hinge, trained, so that only small forces for bending the respective connecting element are required and yet sufficient support and stability for the associated with them ring segments against the centrifugal force in loading and unwinding of the winding tube is given.
In einer Weiterbildung ist noch vorgesehen, die Wickelhülse durch den Mantel bildende Stege, die parallel zu einer Mittelachse des Körpers und gleichabständig über den Umfang verteilt verlaufen, sowie Ringsegmentleisten, die jeweils verschiedene Abschnitte des Mantels voneinander trennen und die senkrecht zu den mit ihnen verbundenen Stegen verlaufen, und verformbare Bogenelemente, die jeweils zwei einen Abschnitt des Mantels unterteilende Ringsegmentleisten miteinander verbinden, auszubilden, wobei gegenüberliegende Stirnflächen benachbarter Ringsegmentleisten miteinander in Kontakt bringbar sind. Die genannten Stirnflächen dienen ebenfalls als Anschlagflächen, die die Reduktion des Umfangs begrenzen.In a further development is still provided, the winding tube through the shell-forming webs which extend parallel to a central axis of the body and gleichabständig distributed over the circumference, and ring segment strips, each separate different portions of the shell from each other and perpendicular to the webs connected to them extend, and deformable arch elements, each of which two subdivide a portion of the shell dividing ring segment strips together form, with opposite end faces of adjacent ring segment strips can be brought into contact with each other. The said end faces also serve as abutment surfaces which limit the reduction of the circumference.
Eine weitere Fortbildung sieht außerdem vor, dass der Mantel auch axial kompressibel ist. Insbesondere wird die axiale Kompressibilität durch Abstandselemente erreicht, die parallel zu den Stegen zwischen zwei Ringsegmentleisten zweier Abschnitte des Mantels verlaufen, wobei die Abstandselemente an jeweils einer ersten Ringsegmentleiste angeordnet sind und mit einer Stirnfläche mit einer zweiten Ringsegmentleiste in Kontakt bringbar sind.Another training also provides that the jacket is also axially compressible. In particular, the axial compressibility is achieved by spacer elements which extend parallel to the webs between two ring segment strips of two sections of the shell, wherein the spacer elements are each arranged on a first ring segment strip and can be brought into contact with an end face with a second ring segment strip.
Vorteilhaft ausgestaltet wird die Erfindung auch dadurch, dass jeweils zwei Ringsegmentleisten zweier Abschnitte durch zwei Bogenelemente miteinander verbunden sind, die vorzugsweise in einer Tangentialebene des Mantels biegbar sind, da die so erreichte Stabilität mit vergleichsweise wenig Materialaufwand gewonnen wird.Advantageously, the invention is also characterized in that in each case two ring segment strips of two sections are interconnected by two arc elements, which are preferably bendable in a tangential plane of the shell, since the stability thus achieved is obtained with relatively little material.
Schließlich wird noch vorgeschlagen, dass ein Endabschnitt einer Wickelhülse in einen an einem gegenüberliegenden Ende angeordneten Endabschnitt einer benachbarten Wickelhülse einschiebbar ist, wobei der Außendurchmesser des einzuschiebenden Endabschnitts geringfügig kleiner als der Innerdurchmesser des aufnehmenden Endabschnitts ist. Hierdurch wird eine Steckbarkeit einer Mehrzahl von Wickelhülsen zu einem Hülsenstapel ermöglicht, was bei einem axialen Pressen, z.B. vor Beginn eines Färbevorgangs in einem Autoklaven, häufig angebracht ist. Die Steckbarkeit bewirkt wegen der angepassten Durch- messer der Endabschnitte eine exakte Führung benachbarter Wickelhülsen in radiale Richtung. Im Gegensatz zu dem übrigen Mantel können die beiden gegenüberliegenden Endabschnitte nicht axial komprimierbar, d.h. in diese Richtung starr ausgebildet sein, so dass sie sich bei Ausübung eines Axialdrucks beim Färben nicht axial verkürzen.Finally, it is proposed that one end section of a winding tube can be inserted into an end section of an adjacent winding tube arranged at an opposite end, the outside diameter of the end section to be inserted being slightly smaller than the inside diameter of the receiving end section. As a result, a plug-in capability of a plurality of cores is made possible to a core stack, which is often attached to an axial pressing, for example, before the start of a dyeing process in an autoclave. Due to the adapted throughput, the plug-in knife the end portions an exact guidance of adjacent cores in the radial direction. In contrast to the rest of the jacket, the two opposite end portions can not be axially compressible, ie rigid in this direction, so that they do not shorten axially during the exercise of axial pressure during dyeing.
Weitere vorteilhafte Ausbildungen sind den übrigen Unteransprüchen entnehmbar.Further advantageous embodiments are the remaining dependent claims.

Die in Figur 1, 2 und 5 in verschiedenen Ansichten gezeigte Wickelhülse 1 besteht aus einem zu einer Mittelachse M rotationssymmetrischen Mantel 2 zur Aufnahme von Wickelgut, einem ersten oberen Endabschnitt 3, der sich stirnseitig an einem oberen Ende des Mantels 2 befindet und einem zweiten Endabschnitt 4, der sich, dem ersten Endabschnitt 3 gegenüberliegend, stirnseitig an einem unteren Ende des Mantels 2 befindet. Jeder der beiden Endabschnitte 3, 4 weist sechs Ringsegmente 6, 6' auf, wobei die Ringsegmente 6 des ersten Endabschnittes 3, dem Steckbund, einen kleineren Radius besitzen als die Ringsegmente 6' des zweiten Endabschnittes 4.The winding tube 1 shown in different views in Figures 1, 2 and 5 consists of a to a central axis M rotationally symmetrical jacket 2 for receiving winding material, a first upper end portion 3, which is located at the front end at an upper end of the shell 2 and a second end portion 4, which, opposite the first end section 3, is located at the front end at a lower end of the jacket 2. Each of the two end sections 3, 4 has six ring segments 6, 6 ', wherein the ring segments 6 of the first end section 3, the plug-in collar, have a smaller radius than the ring segments 6' of the second end section 4.
Die Ringsegmente 6, 6' sind mit ihren, in Figur 4 besonders deutlich gezeigten, Stirnflächen 7, 7' gleichabständig zueinander angeordnet. Jedes Ringsegment 6, 6' ist mittels zweier etwa C-förmig gebogener, flacher Verbindungselemente 8 mit seinem benachbarten Ringsegment 6, 6' verbunden, so dass ein geschlossener ringartiger Endabschnitt entsteht. Jedes Verbindungselement 8 schließt sich dabei an eine äußere Kante 9 einer jeweiligen Stirnfläche 7 zweier Ringsegmente 6, 6' an, erstreckt sich über die gesamte Endabschnittbreite 10, 10' der jeweiligen Endabschnitte 6, 6' und besitzt eine Dicke 11 von etwa 0,5mm.The ring segments 6, 6 'are arranged equidistant to one another with their end faces 7, 7', which are shown particularly clearly in FIG. 4. Each ring segment 6, 6 'is connected by means of two approximately C-shaped, flat connecting elements 8 with its adjacent ring segment 6, 6', so that a closed ring-like end portion is formed. Each connecting element 8 closes at an outer edge 9 of a respective End face 7 of two ring segments 6, 6 ', extends over the entire end portion width 10, 10' of the respective end portions 6, 6 'and has a thickness 11 of about 0.5 mm.
Die Verbindung zwischen dem Mantel 2 und den Endabschnitten 6, 6' wird durch parallel und äquidistant in Längsrichtung der Wickelhülse 1 verlaufende Stege 12 des Mantels 2 hergestellt, wobei jeweils drei Stege 12 einem Ringsegment 6, 6' angeschlossen sind. Wird ein radial in Richtung der Rotationssymmetrieachse wirkender mechanischer Druck auf die Ringsegmente 6 und/oder 6', durch die Schrumpfung von Garn während der thermischen Behandlung ausgeübt, so verringert sich der Umfang des jeweiligen Endabschnittes 3, 4 indem die sich der Abstand zwischen den Stirnflächen 7 verringert. Dabei wird das zwischen zwei Ringsegmenten 6, 6' angeordnete Verbindungselement 8 falzförmig zusammengedrückt, bis sich die Stirnflächen T der Ringsegmente 6, 6' berühren und somit einen Anschlag bilden. Elastisch verformt werden bei der genannten Druckeinwirkung infolge der Schrumpfung auf die beiden Endabschnitte 3, 4, die Verbindungselemente 8 sowie im Mantelbereich 13 die Bogenelemente 17.The connection between the casing 2 and the end sections 6, 6 'is produced by webs 12 of the casing 2 extending parallel and equidistantly in the longitudinal direction of the winding tube 1, three webs 12 each being connected to a ring segment 6, 6'. If a mechanical pressure acting radially in the direction of the rotational symmetry axis is exerted on the ring segments 6 and / or 6 'by the shrinkage of yarn during the thermal treatment, the circumference of the respective end section 3, 4 is reduced by the distance between the end faces 7 reduced. In this case, between two ring segments 6, 6 'arranged connecting element 8 is pressed in a fold-shaped, until the end faces T of the ring segments 6, 6' touch and thus form a stop. The curved elements 17 are elastically deformed during the mentioned pressure action as a result of the shrinkage on the two end sections 3, 4, the connecting elements 8 and in the jacket region 13.
Der Mantelbereich 13 wird neben den Stegen 12 auch von Ringsegmentleisten 14 gebildet, die den Mantel 2 in 12 Abschnitte 15 trennen und die senkrecht zu den mit ihnen verbundenen Stegen 12 verlaufen und mit diesen offene Kassetten 16 bilden. Zudem weist der Mantelbereich 13 verformbare Bogenelemente 17 auf, die jeweils zwei einen Abschnitt 15 des Mantelbereichs 13 trennende Ringsegmentleisten 14 miteinander verbinden. Die Ringsegmentleisten 14 zeigen Stirnflächen 18, die gleichabständig zueinander angeordnet sind, wobei gegenüberliegende Stirnflächen 18 benachbarter Ringsegmentleisten 14 miteinander in Kontakt bringbar sind und einen Anschlag bilden und somit der radialen Verformbarkeit des Mantels 2 eine Grenze setzen.The jacket portion 13 is formed in addition to the webs 12 and ring segment strips 14 which separate the shell 2 in 12 sections 15 and perpendicular to the webs 12 connected to them and form with these open cassettes 16. In addition, the jacket region 13 has deformable arch elements 17 which connect two ring segment strips 14 which each separate a section 15 of the jacket region 13. The ring segment strips 14 show end faces 18 which are arranged gleichabständig to each other, with opposite end faces 18 adjacent ring segment strips 14 are brought into contact with each other and form a stop and thus set the radial deformability of the shell 2 a limit.
Der Mantel 2 ist ebenfalls axial kompressibel. Wird auf die Wickelhülse 1 ein axial wirkender mechanischer Druck ausgeübt, so verformen sich auf je zwei zueinander parallelen Ringsegmentleisten 14 angeordnete Bogenelemente 19 solange, bis Anschlagelemente 20, die seitlich versetzt jeweils auf einer der Ringsegmentleisten 14 angeordnet sind, und die sich jeweils paarweise gegenüberstehen, mit der gegenüberliegenden Ringsegmentleiste 14 in Kontakt treten. Die Figur 3 zeigt vergrößert einen Bereich B der Figur 5. Insbesondere sei darauf verwiesen, dass die Stege 12 und die Ringsegmentleisten 14, die sich im oberen Bereich des ersten Endabschnittes 3 befinden, durch Verschlusselemente 21 geschlossene Kassetten 22 ausbilden, die die Stabilität des Endabschnittes 3 erhöhen und den Flottendurchtritt von Garn in dem Steckbereich verhindern sollen. Der Endabschnitt 4 ist im übrigen gleichfalls mit geschlossenen Kassetten 22 versehen.The jacket 2 is also axially compressible. If an axially acting mechanical pressure is exerted on the winding sleeve 1, then arch elements 19 arranged on each two mutually parallel ring segment strips 14 deform until stop elements 20 which are arranged laterally offset in each case on one of the ring segment strips 14 and which in each case oppose in pairs, come into contact with the opposite ring segment strip 14. 3 shows an enlarged area B of Figure 5. In particular, it should be noted that the webs 12 and the ring segment strips 14, which are located in the upper region of the first end portion 3, formed by closure elements 21 closed cartridges 22, the stability of the end portion 3 and prevent the fleet passage of yarn in the mating area. The end portion 4 is also provided with closed cartridges 22, moreover.
Wie sich insbesondere aus Figur 5 ergibt, ist der Endabschnitt 3 einer Wickelhülse mit seinem Außendurchmesser 3A in den angepassten Endabschnitt 41 einschiebbar, um auf diese Weise für den Färbeprozess einen Stapel von Wickeln zu erzeugen. Die Einstecktiefe 5 beträgt das in Figur 5 veranschaulichte Maß. Die Schulter S an einem Endabschnitt 3 schlägt dabei an die Stirnfläche des gegenüberliegenden Endschnitts 4 einer beim Stapeln benachbarten Wickelhülse 1 an.As can be seen in particular from FIG. 5, the end section 3 of a winding tube with its outside diameter 3A can be inserted into the adapted end section 41 in order to produce a stack of windings for the dyeing process in this way. The insertion depth 5 is the dimension illustrated in FIG. The shoulder S at one end portion 3 strikes against the end face of the opposite end section 4 of a winding tube 1 adjacent to the stacking.
Da beide Endabschnitte 3 und 4 radial komprimierbar, d.h. in ihrem Umfang verkürzbar sind, ist die Steckbarkeit der Wickelhülsen 1 auf ideale Weise mit der radialen Kompri- mierbarkeit der Wickelhülse 1 über deren gesamte axiale Länge kombinierbar und führt zu einem Hülsenstapel mit durchweg gleichem Durchmesser der Wickelhülsen in komprimiertem Zustand. Since both end sections 3 and 4 are radially compressible, ie can be shortened in their circumference, the pluggability of the cores 1 is ideally combinable with the radial compressibility of the winding tube 1 over its entire axial length and leads to a tube stack with the same diameter throughout Winding tubes in compressed condition.
