Abstract

A coil carrier whose shell may be rigid (3; 20) or axially and/or radially compressible (37), has an end ring (1) and an upper ring (2). The upper ring (2) is provided with an axially projecting collar (14) which can be fitted inside the end ring (1) of an adjacent coil carrier of identical construction, at the same time leaving room for a thread reserve which is provided on the collar (14) and thus accommodated in a protected manner, particularly if coil carriers of this kind are placed axially one above the other and the coils located thereon are compressed axially. The measure by which the collar (14)of one coil can be inserted in an axially adjacent coil carrier can be determined by shoulders (9, 13) and extensions (10, 15). This measure can be determined in such a way that a thread can be fed from the thread reserve to a package to be produced or already present on the coil carrier, without becoming jammed.

Description

Die Erfindung bertrifft einen aus zwei Hülsenteilen bestehenden Wickelträger mit im wesentlichen zylindrischer Mantelfläche zur Aufnahme eines Garnwickels, wobei jeder Hülsenteil in Achsrichtung des Wickelträgers verlaufende, durch Ringelemente miteinander käfigartig verbundene Tragelemente hat und beide Hülsentiele axial ineinanderschiebbar sind.The invention relates to a winding carrier consisting of two core parts with a substantially cylindrical outer surface for receiving a yarn package, each core part having cage-like support elements running in the axial direction of the core carrier and the two core parts being axially insertable.

Bei einem bekannten Wickelträger dieser Art (DE-GM 71 02 230) sind beide Hülsenteile mit einem radial nach außen vorstehenden Endring versehen. Dabei ist insbesondere nachteilig, daß bei diesem bekannten Wickelträger keine Fadenreserve gebildet werden kann, die auch nach axialem Zusammendrücken des Wickelträgers und des darauf befindlichen Wickels noch frei zugänglich ist.In a known winding carrier of this type (DE-GM 71 02 230), both sleeve parts are provided with a radially outwardly projecting end ring. It is particularly disadvantageous that in this known winding carrier no thread reserve can be formed, which is still freely accessible even after the winding carrier and the winding located thereon have been compressed.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Wickelträger der eingangs erwähnten Art so auszubilden, daß er auch bei axialer Kompression die Bildung einer stets frei zugänglichen Fadenreserve ermöglicht.Based on this prior art, the invention has for its object to form a bobbin of the type mentioned so that it allows the formation of a freely accessible thread reserve even with axial compression.

Diese Aufgabe wird erfindungsgemäß bei einem Wickelträger der eingangs erwähnten Art dadurch gelöst, daß das axial äußere Ende nur eines der Hülsenteile mit einem in Umfangsrichtung geschlossenen Anlaufring versehen ist, der eine über die von den Tragelementen gebildete Wickelfläche radial nach außen vorstehende Anlaufringfläche und an seinem radial innen liegenden Rand eine Abdeckfläche und eine dieser gegenüber weiter radial nach innen versetzte Führungsfläche aufweist, und daß an dem axial äußeren Ende des anderen Hülsenteils ein in bezug auf die Wickelfläche radial nach innen versetzter, axial über die Tragelemente hinaus vorstehender Ringkörper vorgesehen ist, dessen Außenflächenradius gleich oder geringfügig kleiner ist als der Radius der Führungsfläche des Anlaufrings.This object is achieved in a winding carrier of the type mentioned above in that the axially outer end of only one of the sleeve parts is provided with a circumferentially closed thrust ring which has a thrust ring surface projecting radially outward beyond the winding surface formed by the supporting elements and on its radially inner edge has a cover surface and a guide surface which is offset further radially inwards, and that at the axially outer end of the other sleeve part there is provided an annular body which projects radially inwards with respect to the winding surface and projects axially beyond the support elements, the outer surface radius of which is equal to or slightly smaller than the radius of the guide surface of the thrust ring.

Der radial nach außen über die Wickelfläche vorstehende Anlaufring gewährleistet, daß die Spultrommel beim Anspulen nur an diesem Ring angreift und nicht an den die Wickelfläche bildenden Tragelementen sowie den ersten darauf gewickelten Garnlagen.The thrust ring projecting radially outward beyond the winding surface ensures that the winding drum only acts on this ring during winding and not on the support elements forming the winding surface and the first layers of yarn wound thereon.

Auf dem Ringkörper kann eine gesicherte Fadenreserve untergebracht werden, die in ihrer gesamten Länge vollkommen freiliegt und nicht verschoben oder beschädigt werden kann.A secured thread reserve can be accommodated on the ring body, the entire length of which is completely exposed and cannot be moved or damaged.

Wenn derartige Wickelträger, wie das bei axialer Kompression üblich ist, axial ineinandergesetzt werden, dann greift der Ringkörper des einen Wickelträgers in den Anlaufring des axial benachbarten Wickelträgers ein, wobei die Außenfläche des Ringkörpers mit der Führungfläche des Anlaufrings zusammenarbeitet. Die Abdeckfläche des Anlaufrings deckt dabei einen weiteren Teil der Außenfläche des Ringkörpers ab. In diesem abgedeckten Bereich des Ringkörpers kann somit eine Fadenreserve untergebracht werden, die beim axialen Ineinandersetzen derartiger Wickelträger völlig geschützt ist und folglich nach einer axialen Kompression und nach dem Auflösen der Wikkelträgersäule in einzelne Wickelträger frei zugänglich ist.If such winding carriers are axially nested, as is usual with axial compression, then the ring body of one winding carrier engages in the thrust ring of the axially adjacent winding carrier, the outer surface of the ring body cooperating with the guide surface of the thrust ring. The cover surface of the thrust ring covers a further part of the outer surface of the ring body. In this covered area of the ring body, a thread reserve can thus be accommodated, which is completely protected when such winding carriers are axially interlaced and is consequently freely accessible after axial compression and after the winding support column has been dissolved into individual winding carriers.

Dieser Wickelträger eignet sich insbesondere dazu, Garnwickel auf einem Färbeschwert oder einem -speer säulenartig zusammenzustellen, wobei dann die Färbeflotte durch die Mantelwandung der Wickelträger und der darauf befindlichen Wickel hindurchgeführt wird. Die einzelnen Wickel können bei der axialen Kompression unmittelbar aneinander zur Anlage kommen und somit eine Säule bilden, deren Dichte und damit auch Strömungswiderstand über die gesamte Länge homogen ist. Eine solche Verdichtung kann aber auch allein oder zusätzlich zu dem Zweck erfolgen, das Abspulen des Wickels zu vereinfachen, indem durch axiale Kompression der Wickel die beim Bespulen erzeugten Kreuzungswinkel reduziert werden, so daß sich der Faden beim Anspulen nur noch relativ geringfügig in axialer Richtung verlagert.This winding support is particularly suitable for assembling yarn packages in a column-like manner on a dyeing sword or spear, in which case the dyeing liquor is then passed through the jacket wall of the winding support and the packages located thereon. In the case of axial compression, the individual coils can come into direct contact with one another and thus form a column whose density and thus also the flow resistance are homogeneous over the entire length. Such compression can also be done alone or in addition to the purpose of simplifying the unwinding of the winding by reducing the crossing angle generated during winding by axial compression of the winding, so that the thread only relatively slightly displaces in the axial direction during winding .

Der erfindungsgemäße Wickelträger kann ferner so ausgebildet sein, daß die Abdeckfläche und die Führungsfläche des Anlaufrings koaxial verlaufen. Während die Führungsfläche jeweils zwei axial benachbarte Wickelträger zueinander ausrichtet, ergibt die Abdeckfläche einen geschützten Raum zur Unterbringung der Fadenreserve.The winding support according to the invention can also be designed so that the cover surface and the guide surface of the thrust ring run coaxially. While the guide surface aligns two axially adjacent winding carriers with each other, the cover surface provides a protected space for accommodating the thread reserve.

Der erfindungsgemäße Wickelträger kann ferner so ausgebildet sein, daß die Endabschnitte der den Ringkörper tragenden Tragelemente radial außenfläche des Ringkörpers mit radialem Abstand davon enden. Auf diese Weise wird ein ungestörter Fadenübergang von der Fadenreserve zum Wickel sichergestellt.The winding support according to the invention can also be designed such that the end sections of the support elements carrying the ring body end radially at the outer surface of the ring body at a radial distance therefrom. In this way, an undisturbed thread transition from the thread reserve to the winding is ensured.

Der erfindungsgemäße Wickelträger kann ferner so ausgebildet sein, daß das im Bereich der Längsmitte liegende Ende eines Hülsenteils mit einem Sperring verbunden ist, der über Sollbruchstellen mit radial innen liegenden Flächen der Tragelemente in Verbindung steht, während die im Bereich der Längsmitte des Wickelträgers liegenden Enden der Tragelemente des anderen Hülsenteils fest auf der Außenfläche eines Stützrings sitzen und der Sperring sowie der Stützring axial aneinander zur Anlage kommen. Der Sperring definiert dabei die axiale Länge der Hülse vor der Kompression. Bei Überschreiten eines Grenzwertes für den Axialdruck löst sich der Sperring von den Tragelementen und gleitet mit dem Stützring in Richtung auf den Anlaufring. Sperring und Stützring tragen zu einer radialen Aussteifung des Wickelträgers bei. Dabei kann der Sperring eine Führung ergeben, die mit einem Färbeschwert oder -speer zusammenarbeitet.The winding support according to the invention can also be designed such that the end of a sleeve part lying in the region of the longitudinal center is connected to a locking ring which is connected via predetermined breaking points to radially inner surfaces of the support elements, while the ends lying in the region of the longitudinal center of the winding carrier Support elements of the other sleeve part sit firmly on the outer surface of a support ring and the locking ring and the support ring come into axial contact with one another. The locking ring defines the axial length of the sleeve before compression. If a limit value for the axial pressure is exceeded, the locking ring releases from the support elements and slides with the support ring in the direction of the thrust ring. Locking ring and support ring contribute to a radial stiffening of the winding carrier. The lock ring can provide a guide that works with a dyeing sword or spear.

Der erfindungsgemäße Wickelträger kann so ausgebildet sein, daß der Sperring einen Aufnahmeabschnitt hat, der in bezug auf die ihn tragenden Tragelemente radial nach innen versetzt ist, und daß der Stützring in den Raum zwischen dem Aufnahmeabschnitt und den diesen tragenden Tragelementen eingreift. Somit greift der Stützring in eine Art Ringnut ein, die von Sperring und den ihn tragenden Tragelementen definiert ist. Dabei entsteht eine Klemmverbindung, welche die beiden Hülsenteile lösbar aneinander festlegt. Der Stützring kann damit in der Ausgangsposition des Wickelträgers mit der erforderlichen Sicherheit festgelegt werden.The winding support according to the invention can be designed so that the locking ring has a receiving portion which is offset radially inward with respect to the supporting elements carrying it, and that the support ring in the space between the Receiving section and engages the supporting elements carrying them. Thus, the support ring engages in a kind of ring groove, which is defined by the locking ring and the supporting elements carrying it. This creates a clamp connection, which releasably fixes the two sleeve parts together. The support ring can thus be fixed in the starting position of the winding carrier with the required security.

Der erfindungsgemäße Wickelträger kann so ausgebildet sein, daß die beiden Hülsenteile über den Sperring und den Stützring in der Art einer Schnappverbindung miteinander verbunden sind. Wenn die Hülsenteile ineinandergesteckt sind, dann sind sie nur unter Kraftaufwendung wieder lösbar. Die Schnappverbindung kann in vielfältiger Weise dadurch gebildet werden, daß zumindest ein vorspringender Abschnitt eines Hülsenteils einen vorspringenden Abschnitt des anderen Hülsenteils nachgiebig übergreift oder in eine Vertiefung dieses anderen Hülsenteils eingreift.The winding support according to the invention can be designed such that the two sleeve parts are connected to one another via the locking ring and the support ring in the manner of a snap connection. If the sleeve parts are inserted into one another, then they can only be detached again with the application of force. The snap connection can be formed in a variety of ways in that at least one projecting section of one sleeve part resiliently engages over a projecting section of the other sleeve part or engages in a recess of this other sleeve part.

Der erfindungsgemäße Wickelträger kann so ausgebildet sein, daß die Tragelemente in Richtung auf die Längsachse des Wikkelträgers nachgiebig sind. Diese Nachgiebigkeit, die durch Werkstoffauswahl, Dimensionierung und Konstruktion erreicht werden kann, ermöglicht es, bei Auftreten entsprechender nach radial innen gerichteter Drücke einem Schrumpfen des Garnwikkels zu folgen.The winding support according to the invention can be designed such that the support elements are flexible in the direction of the longitudinal axis of the winding support. This flexibility, which can be achieved through material selection, dimensioning and construction, makes it possible to follow a shrinkage of the yarn reel if corresponding pressures directed radially inward occur.

Der erfindungsgemäße Wickelträger kann schließlich so ausgebildet sein, daß der Ringkörper, der Sperring und der Stützring in Richtung auf die Längsachse des Wickelträgers nachgiebig sind. Diese Nachgiebigkeit, die durch Werkstoffauswahl, Dimensionierung und Konstruktion erreicht werden kann, trägt ebenfalls dazu bei, bei Auftreten entsprechender nach radial innen gerichteter Drücke einem Schrumpfen des Garnwikkels zu folgen.The winding support according to the invention can finally be designed such that the ring body, the locking ring and the support ring are flexible in the direction of the longitudinal axis of the winding support. This flexibility, which can be achieved through material selection, dimensioning and construction, also contributes to the shrinkage of the yarn reel when corresponding radially inward pressures occur.

Der hier verwendete Begriff « zylindrisch " umfaßt auch Abweichungen von einer rein mathematischen zylindrischen Form, welche sich insbesondere aufgrund des Schrumpfverhaltens der verwendeten Werkstoffe und aufgrund von Erfordernissen der Entformungsvorgänge ergeben.The term "cylindrical" used here also includes deviations from a purely mathematical cylindrical shape, which result in particular from the shrinking behavior of the materials used and from the requirements of the demolding processes.

Der Wickelträger gemäß dem in den Figuren dargestellten Ausführungsbeispiel hat ein unteres Hülsenteil, das nachstehend als Fußteil 1 bezeichnet wird, und ein oberes Hülsenteil, das nachstehend als Kopfteil 2 bezeichnet wird.The winding support according to the exemplary embodiment shown in the figures has a lower sleeve part, which is referred to below as foot part 1, and an upper sleeve part, which is referred to below as head part 2.

Zunächst soll das Fußteil 1 insbesondere anhand der Fig. 1, 7 und 8 beschrieben werden.First, the foot part 1 is to be described in particular with reference to FIGS. 1, 7 and 8.

Es hat an dem axialen Ende, welches auch ein Ende des gesamten Wickelträgers bildet, einen Anlaufring 3. Dieser Anlaufring 3 bildet an seiner radial außen liegenden Fläche eine Anlaufringfläche 4, die über den gesamten Umfang geschlossen verläuft. Auf der radial nach innen weisenden Seite seines Querschnitts hat der Anlaufring 3 eine vom Ende des Fußteils 1 ausgehende Abdeckfläche 5, die durch eine Schulter 6 begrenzt ist. An diese Schulter 6 schließt sich gegenüber der Abdeckfläche 5 radial nach innen versetzt eine im wesentlichen zylindrische Führungsfläche 7 an. Diese wird durch eine nach innen vorspringende Schulter 8 begrenzt, welche eine Durchtrittsöffnung 9 freiläßt.It has a thrust ring 3 at the axial end, which also forms one end of the entire winding support. This thrust ring 3 forms a thrust ring surface 4 on its radially outer surface, which runs closed over the entire circumference. On the radially inward-facing side of its cross-section, the thrust ring 3 has a cover surface 5 which extends from the end of the foot part 1 and is delimited by a shoulder 6. An essentially cylindrical guide surface 7 adjoins this shoulder 6 with respect to the cover surface 5, offset radially inwards. This is delimited by an inwardly projecting shoulder 8, which leaves a passage opening 9 free.

An den Anlaufring 3 schließen sich im wesentlichen parallel zur Achse 10 des Fußteils 1 verlaufende Tragelemente 11 an, deren radial außen liegende Kanten 12 eine zylindrische Wikkelfläche definieren. Die Tragelemente 11 sind gleichmäßig über den Umfang des Fußteils 1 verteilt und haben parallel zueinander verlaufende Seitenflächen 13, die im wesentlichen radial in bezug auf die Achse 10 gerichtet sind. Sie haben radial innen liegenden Kanten 14, welche aus Entformungsgründen in Richtung auf den Anlaufring 3 divergieren.The thrust ring 3 is adjoined by support elements 11 which run essentially parallel to the axis 10 of the foot part 1 and whose radially outer edges 12 define a cylindrical winding surface. The support elements 11 are evenly distributed over the circumference of the foot part 1 and have side surfaces 13 which run parallel to one another and are directed essentially radially with respect to the axis 10. They have radially inner edges 14 which diverge in the direction of the thrust ring 3 for demolding reasons.

An den Enden, die bei zusammengebautem Wickelträger im Bereich von dessen Längsmitte liegen, verlaufen die äußeren Kanten 12 der Tragelemente bei 15 radial nach innen geneigt. Nahe diesen Enden der Tragelemente 11 ist ein Sperring 16 vorgesehen, der über Sollbruchstellen 17 mit den innen liegenden Kanten 14 der Tragelemente 11 verbunden ist. Dieser Sperring 16 hat in seinem Querschnitt eine sich an die Sollbruchstellen 17 anschließende Druckschulter 18 und darauffolgend einen im wesentlichen zylindrischen Aufnahmeabschnitt 19, der in einen radial nach innen weisenden Ringabschnitt 20 übergeht, welche eine zentrale Öffnung 21 freiläßt.At the ends which, when the winding support is assembled, lie in the region of its longitudinal center, the outer edges 12 of the support elements at 15 extend radially inwards. A locking ring 16 is provided near these ends of the support elements 11 and is connected via predetermined breaking points 17 to the inner edges 14 of the support elements 11. In its cross-section, this locking ring 16 has a pressure shoulder 18 adjoining the predetermined breaking points 17 and subsequently an essentially cylindrical receiving section 19 which merges into a ring section 20 pointing radially inwards, which leaves a central opening 21 open.

Anschließend soll nun der obere Hülsenteil, also der Kopfteil 2, insbesondere anhand der Fig. 1, 5 und 6 beschrieben werden.The upper sleeve part, ie the head part 2, will now be described in particular with reference to FIGS. 1, 5 and 6.

Er hat an dem Ende, welches ein Ende des Wickelträgers bildet, einen Ringkörper 25 mit einer Außenfläche 26, der ein normal dazu verlaufender Ringabschnitt 27 folgt. Von dem Ringkörper 25 gehen Tragelemente 28 aus, welche parallel zur Achse 29 des Kopfteils 2 verlaufen. Die Tragelemente 28 sind gleichmäßig über den Umfang des Kopfteils 2 verteilt und haben Außenkanten 30, die eine zylindrische Wickelfläche definieren. An dem Ende, das bei zusammengebautem Wickelträger im Bereich von dessen Längsmitte liegt, haben die Außenkanten 30 eine zur Achse 29 hin abfallende Neigung 31. Zur Aussteifung der Verbindung zwischen den Tragelementen 28 und dem Ringkörper 25 sind Ansätze 31 vorgesehen. Die Tragelemente 28 haben ferner einen Abschnitt 32, der über den Ringabschnitt 27 hinausreicht und mit radialem Abstand zur Außenfläche 26 endet.At the end, which forms one end of the winding carrier, it has an annular body 25 with an outer surface 26, which is followed by an annular section 27 running normally to it. Support elements 28 extend from the ring body 25 and run parallel to the axis 29 of the head part 2. The support members 28 are even over the order beginning of the head part 2 distributed and have outer edges 30 which define a cylindrical winding surface. At the end, which, when the winding support is assembled, lies in the area of its longitudinal center, the outer edges 30 have a slope 31 that slopes toward the axis 29. The support elements 28 also have a section 32 which extends beyond the ring section 27 and ends at a radial distance from the outer surface 26.

Die Tragelemente 28 haben ferner radial innen liegende Kanten 33, die in Richtung auf den Ringkörper 25 divergieren.The support elements 28 also have radially inner edges 33 which diverge in the direction of the ring body 25.

An dem Ende der Tragelemente 28, das bei zusammengebautem Wickelträger im Bereich der Längsmitte dieses Wickelträgers liegt, ist an die Innenkanten 33 des Kopfteils 2 ein Stützring 34 angesetzt, .der einen Stimabschnitt 35 und daran anschließend einen Endabschnitt 36 geringerer Wandstärke aufweist.At the end of the support elements 28, which lies in the region of the longitudinal center of this winding support when the winding support is assembled, a support ring 34 is attached to the inner edges 33 of the head part 2, which has a stimulating section 35 and then an end section 36 of lesser wall thickness.

Der Fußteil 1 und der Kopfteil 2 werden zunächst jeder für sich, insbesondere aus Kunststoff, hergestellt. Anschließend werden diese beiden Teile mit fluchtenden Achsen 10 und 29 ineinandergefügt, wobei der Stirnabschnitt 35 des Stützrings 34 des Kopfteils 2 auf dem Aufnahmeabschnitt 19 und an der Druckschulter 18 des Sperrings 16 zur Anlage kommt. Ein ringförmiger Vorsprung 40 des Stirnabschnitts 35 greift dann in eine Rille 41 des Aufnahmeabschnitts 19 ein, so daß eine Schnappverbindung gebildet wird, die die beiden Hülsenteile 1, 2 zusammenhält und nur unter Kraftaufwand gelöst werden kann. Die Tragelemente 11 des Fußteils 1 liegen dabei jeweils zwischen zwei Tragelementen 28 des Kopfteils 2. In diesem zusammengebauten Zustand kann der Wickelträger in üblicher Weise bespult, also mit einem nicht dargestellten Wickel versehen werden. Zu Beginn des Spulvorgangs kann dabei auf der Außenfläche 26 des Ringkörpers 25 nahe dem Ringabschnitt 27 eine Fadenreserve gebildet werden, von der ausgehend der Faden zwischen zwei Abschnitten 32 hindurch zum übrigen Wickel verläuft.The foot part 1 and the head part 2 are initially each made individually, in particular from plastic. Subsequently, these two parts are aligned with aligned axes 10 and 29, the end section 35 of the support ring 34 of the head part 2 coming to rest on the receiving section 19 and on the pressure shoulder 18 of the locking ring 16. An annular projection 40 of the end section 35 then engages in a groove 41 in the receiving section 19, so that a snap connection is formed which holds the two sleeve parts 1, 2 together and can only be released with the application of force. The support elements 11 of the foot part 1 each lie between two support elements 28 of the head part 2. In this assembled state, the winding support can be spooled in the usual way, that is to say can be provided with a winding (not shown). At the beginning of the winding process, a thread reserve can be formed on the outer surface 26 of the ring body 25 near the ring section 27, from which the thread runs between two sections 32 to the rest of the winding.

Derart bespulte Wickelträger können nun axial übereinander angeordnet werden, wobei der Ringkörper 25 eines Wickelträgers mit einer Führungsfläche 7 eines axial benachbarten gleich ausgebildeten Wickelträgers zusammenarbeitet. Dabei überdeckt die gegenüber der Führungsfläche 7 radial nach außen zurückspringende Abdeckfläche 5 die auf der Außenfläche 26 des Ringkörpers 25 vorliegende Fadenreserve. Bei dieser säulenartigen Zusammenstellung von Wickelträgern kann nun eine axiale Kompression erfolgen, bei der Fußteil 1 und Kopfteil 2 jedes Wickelträgers in axialer Richtung ineinandergeschoben werden. Die maximal mögliche Zusammenschiebung dieser beiden Teile ist in Fig. 3 dargestellt. Beim Zusammenschieben werden auch die Wickel axial komprimiert, wobei alle Wickel eine durchgehende Garnsäule bilden. Bei diesem axialen Zusammendrücken wird die auf der Außenfläche 26 untergebrachte Fadenreserve in keiner Weise tangiert. Sie ist daher frei zugänglich, wenn die einzelnen Wickelträger nach der Kompression wieder voneinander werden.Winding carriers wound in this way can now be arranged axially one above the other, the ring body 25 of a winding carrier cooperating with a guide surface 7 of an axially adjacent, identical winding carrier. In this case, the cover surface 5, which protrudes radially outward relative to the guide surface 7, covers the thread reserve present on the outer surface 26 of the ring body 25. With this column-like arrangement of winding carriers, axial compression can now take place, in which the foot part 1 and head part 2 of each winding carrier are pushed into one another in the axial direction. The maximum possible compression of these two parts is shown in Fig. 3. When they are pushed together, the bobbins are also axially compressed, with all bobbins forming a continuous column of yarn. During this axial compression, the thread reserve accommodated on the outer surface 26 is in no way affected. It is therefore freely accessible when the individual winding carriers become separated from one another again after compression.

Die axiale Kompression der Wickel und damit die Bildung einer homogenen Garnsäule führt zu gleichen Durchströmungsbedingungen für eine Färbeflotte, welche durch die Wickel hindruchgepreßt wird. Die axiale Kompression der .Wickel bewirkt aber ferner, daß der beim Bespulen der Wickelträger entstandene Kreuzungswinkel des Garns verändert wird, indem die einzelnen Garnwindungen einen größeren Winkel mit der Achse des Wickelträgers bilden, der Faden beim Abwickeln also nur um einen reduzierten Betrag in Achsrichtung verlagert wird.The axial compression of the packages and thus the formation of a homogeneous yarn column leads to the same flow conditions for a dyeing liquor which is pressed through by the packages. The axial compression of the. Winding also has the effect that the crossing angle of the yarn that occurs when the winding carrier is wound is changed by the individual thread turns forming a larger angle with the axis of the winding carrier, so that the thread is only displaced in the axial direction by a reduced amount becomes.

Zum Zusammenpressen des Wickelträgers in axialer Richtung ist es erforderlich, daß der axial wirkende Druck soweit ansteigt, daß die Sollbruchstellen 17 abreißen und den Sperring 16 damit von den Tragelementen 11 lösen. Wenn das erfolgt ist, verlagert sich sich der Sperring 15 gemeinsam mit dem Stützring 34 in Richtung auf den Anlaufring 3. Die zentrale Öffnung 21 des Sperrings 16 kann dabei als Führung auf einem nicht dargestellten Färbespeer oder -schwert verwendet werden.To compress the winding carrier in the axial direction, it is necessary that the axially acting pressure increases to such an extent that the predetermined breaking points 17 tear off and thus detach the locking ring 16 from the supporting elements 11. When this is done, the locking ring 15 moves together with the support ring 34 in the direction of the thrust ring 3. The central opening 21 of the locking ring 16 can be used as a guide on a dye spear or sword, not shown.

Die Anlaufringfläche 4 des Anlaufrings 3 hat einen geringfügig größeren Durchmesser als die zylindrische Wickelfläche, welche gemeinsam von den Außenkanten der Tragelemente 11 des Fußteils 1 und des Kopfteils 2 gebildet wird. Der Wickelträger kann also zum Bespulen dadurch in Drehung versetzt werden, daß auf dieser Anlaufringfläche 4 eine Anlauftrommel kraftschlüssig abrollt.The thrust ring surface 4 of the thrust ring 3 has a slightly larger diameter than the cylindrical winding surface, which is formed jointly by the outer edges of the support elements 11 of the foot part 1 and the head part 2. The winding support can therefore be set in rotation for winding by a non-positive rolling of a starting drum on this thrust ring surface 4.
