Description

Die Erfindung betrifft einen Wickelträger mit parallel zu seiner Achse verlaufenden, miteinander verbundenen Tragelementen, die radial nach außen in eine gemeinsame Zylinderfläche hineinragen.The invention relates to a winding carrier with mutually parallel support elements that run parallel to its axis and project radially outward into a common cylinder surface.

Es sind bereits Wickelträger für Faden- und Garnwickel bekannt, die in axialer Richtung zusammengedrückt oder zusammengeschoben werden können und zur Naßbehandlung von Faden- und Garnwickeln, beispielsweise zum Färben, Verwendung finden.There are already known winding carriers for thread and yarn packages which can be compressed or pushed together in the axial direction and are used for the wet treatment of thread and yarn packages, for example for dyeing.

Ein bekannter Wickelträger dieser Art besteht aus zwei Hülsenteilen, die jeweils gleiche Durchmesser aufweisen und in Umfangsrichtung in gleichen Abständen voneinander angeordnete, parallel zur Achse verlaufende Tragelemente haben, wobei die Tragelemente des einen Hülsenteils in Zwischenräume zwischen den Tragelementen des anderen Hülsenteils eingreifen.A known winding carrier of this type consists of two sleeve parts, each having the same diameter and having circumferentially equally spaced support elements running parallel to the axis, the support elements of one sleeve part engaging in spaces between the support elements of the other sleeve part.

Darüber hinaus ist auch ein Wickelträger bekannt, der für sich allein nicht zusammendrückbar ist, der aber mit gleichartigen Wickelträgern axial fluchtend zusammenarbeitet. Dieser Wickelträger hat parallel zu seiner Achse verlaufende Tragelemente, die an einem Endring befestigt sind. In diesem Endring ist zwischen jeweils zwei Tragelementen ein Durchbruch vorgesehen, in den ein Tragelement eines benachbarten Wickelträgers eingeführt werden kann. Somit ist es auch bei diesem bekannten Wickelträger möglich, die axiale Ausgangslänge durch Zusammendrücken zu reduzieren.In addition, a winding carrier is also known which cannot be compressed by itself, but which cooperates axially in alignment with similar winding carriers. This winding support has parallel to its axis support elements which are attached to an end ring. In this end ring, an opening is provided between two support elements, into which a support element of an adjacent winding support can be inserted. It is thus also possible with this known winding carrier to reduce the axial initial length by compressing it.

Es ist ferner ein Wickelträger bekannt, der einen in axialer und radialer Richtung nachgiebigen Mantel aufweist, der aus elastisch und/oder plastisch nachgiebigen Elementen und aus diese Elemente verbindenden starren, in axialer Richtung verlaufenden Längsstegen gebildet ist. Dabei sind die nachgiebigen Elemente in axialer Richtung in Abstand voneinander angeordnete Ringe und die diese Ringe verbindenden, in axialer Richtung aufeinanderfolgenden Längsstege sind in Umfangsrichtung gegeneinander versetzt. Dies führt bei dem bekannten Wickelträger dazu, daß sein Mantel bei einem axialen Zusammendrücken zwangsläufig eine Durchmesserverringerung erfährt.A winding carrier is also known which has a jacket which is flexible in the axial and radial directions and which is formed from elastically and / or plastically flexible elements and from rigid longitudinal webs connecting these elements and extending in the axial direction. The resilient elements are spaced apart from each other in the axial direction and the longitudinal webs that connect these rings and follow one another in the axial direction are offset in the circumferential direction. In the known winding carrier, this leads to the fact that its jacket inevitably undergoes a reduction in diameter when axially compressed.

Die Herstellung eines solchen bekannten Wickelträgers erfordert eine relativ aufwendige Form und ergibt darüber hinaus die nicht immer gewünschte zwangsläufige Koppelung zwischen einem axialen Zusammendrücken und einer Durchmesserverringerung. Ein Ineinanderstecken dieser Wickelträger ist auch zur Reduzierung des erforderlichen Transportvolumens nicht möglich.The production of such a known winding carrier requires a relatively complex shape and moreover results in the inevitable coupling between an axial compression and a reduction in diameter. It is also not possible to insert these winding carriers into one another in order to reduce the required transport volume.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, einen Wickelträger der eingangs erwähnten Art dahingehend auszubilden, daß er in Verbindung mit gleichartigen Wickelträgern ein Zusammendrücken der Faden- oder Garnwickel in Achsrichtung und auch eine Durchmesserreduzierung gestattet, wobei beide Effekte nicht zwangsläufig gekoppelt sind. Dies soll erreicht werden bei einem einfachen Aufbau und damit bei einer problemlosen Herstellbarkeit des Wickelträgers.The object of the present invention is now to design a bobbin of the type mentioned in such a way that, in conjunction with similar bobbins, it allows the thread or yarn bobbins to be compressed in the axial direction and also a diameter reduction, the two effects not necessarily being coupled. This should be achieved with a simple structure and thus with a problem-free manufacture of the winding carrier.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die einzelnen Tragelemente in Umfangsrichtung zusammendrückbar ausgebildet sind, daß zwischen zwei benachbarten Tragelementen im.wesentlichen formstabile Koppelstücke vorgesehen sind und daß der Zwischenraum zwischen zwei benachbarten Tragelementen größer ist, als es der Abmessung eines Tragelements in Umfangsrichtung entspricht. Mehrere Wickelträger dieser Art können zum Teil ineinander geschoben werden, um damit die axiale Länge von Faden- und Garnwickeln zu reduzieren. Durch ein Zusammendrücken der Tragelemente in Umfangsrichtung ergibt sich eine Verkürzung des Umfangs und damit eine Durchmesserreduzierung. Es wird also durch einen so ausgebildeten, äußerst einfach aufgebauten Wickelträger der Effekt eines sowohl axial als auch radial zusammendrückbaren Wickelträgers herbeigeführt.This object is achieved in that the individual support elements are designed to be compressible in the circumferential direction, that essentially dimensionally stable coupling pieces are provided between two adjacent support elements, and that the space between two adjacent support elements is larger than the dimension of a support element in the circumferential direction. Several bobbins of this type can be partially pushed into each other in order to reduce the axial length of thread and yarn packages. By compressing the support elements in the circumferential direction, the circumference is shortened and the diameter is reduced. It is so through a trained, extremely simple winding carrier of the Ef effect brought about a compressible both axially and radially compressible winding carrier.

Die Erfindung sieht vor, daß jedes Tragelement ein radial nach innen offenes V-förmiges Querschnittsprofil mit aufeinanderzu zusammendrückbaren Schenkeln hat. Es kommen aber auch weitere Querschnittsprofile in Betracht, beispielsweise U-förmige sowie bogenförmige.The invention provides that each support element has a radially inwardly open V-shaped cross-sectional profile with compressible legs. However, other cross-sectional profiles can also be considered, for example U-shaped and curved ones.

Nach einer weiteren Ausführungsform der Erfindung ist vorgesehen, daß jedes Tragelement aus zwei parallel zueinander verlaufenden Schenkeln gebildet ist, die im Bereich der Enden des Wickelträgers miteinander verbunden sind. Bei beiden Ausführungsformen der Tragelemente handelt es sich um einfache, in Umfangsrichtung zusammendrückbare Profile.According to a further embodiment of the invention, it is provided that each support element is formed from two legs that run parallel to one another and are connected to one another in the region of the ends of the winding support. Both embodiments of the support elements are simple profiles that can be compressed in the circumferential direction.

Die Erfindung sieht weiter vor, daß die Innenflächen der Tragelemente zumindest in dem über das äußerste Koppelstück vorstehenden Bereich auf einer Zylinderfläche liegen, deren Durchmesser gleich oder größer ist als der Durchmesser, auf dem die Außenflächen dieses Koppelstücks angeordnet sind. Daraus folgt, daß die Tragelemente eines Wickelträgers ein Koppelstück oder die Koppelstücke eines anderen Wickelträgers übergreifen können. Die Abmessungen können dabei so gewählt werden, daß die Innenflächen der Tragelemente auf den Außenflächen der Koppelstücke geführt werden. Die Koppelstücke können dabei auch als Begrenzung für das Maß, um welches zwei benachbarte Wickelträger maximaL ineinandergeschoben werden können, benutzt werden.The invention further provides that the inner surfaces of the support elements lie at least in the area protruding beyond the outermost coupling piece on a cylinder surface whose diameter is equal to or larger than the diameter on which the outer surfaces of this coupling piece are arranged. It follows that the support elements of a winding support can overlap a coupling piece or the coupling pieces of another winding support. The dimensions can be chosen so that the inner surfaces of the support elements are guided on the outer surfaces of the coupling pieces. The coupling pieces can also be used to limit the extent by which two adjacent winding carriers can be pushed together.

Schließlich sieht die Erfindung noch vor, daß der Wickelträger mindestens einen Führungsring aufweist, an dem sich mit den Koppelstücken verbundene, nachgiebige Knickelemente abstützen. Auf diese Weise wird einerseits eine sichere Führung des Wickelträgers und andererseits eine zuverlässige Abstützung der Tragelemente bewirkt.Finally, the invention also provides that the winding support has at least one guide ring, on which resilient buckling elements connected to the coupling pieces are supported. In this way, a secure guidance of the winding support and, on the other hand, a reliable support of the support elements is effected.

Die Tragelemente 1 haben radial außenliegende Scheitelflächen 3, die auf einer gemeinsamen zylindrischen Hüllfläche liegen.The embodiment of the winding carrier according to the invention according to FIGS. 1 and 2 has supporting elements 1 running parallel to the axis of the winding carrier. Each support element 1 has a V-shaped cross section, which is open radially inwards. It is thus formed by two legs 2 which can be pressed together in the direction of one another. The support elements 1 have radially outer apex surfaces 3, which lie on a common cylindrical envelope surface.

Alle Tragelemente 1 des Wickelträgers sind an seinem einen Ende durch Verbindungselemente 4 gekoppelt, von denen jeweils eines zwischen zwei Tragelementen 1 angeordnet ist. Diese Verbindungselemente 4 sind im wesentlichen formstabil. Sie haben jeweils einen radial nach innen offenen Durchbruch 5, der geringfügig größer ist, als es den Abmessungen eines Tragelementes 1 in nicht zusammengedrückter Stellung entspricht. Daraus ergibt sich, daß die Durchbrüche 5 vorteilhaft ebenfalls eine V-förmige Ausbildung haben. Die Verbindungselemente 4 stehen radial nach außen hin über die den Tragelementen 1 gemeinsame Hüllfläche hinaus vor. Sie sind an ihren radial innenliegenden Umfangskanten 6 scharnierartig mit je einem Tragelement 1 verbunden, so daß sich die Lage des Schenkels 2 eines solchen Tragelements 1 gegenüber dem zugehörigen Verbindungselement 4 ohne weiteres durch Zusammendrücken des Tragelements 1 verändern läßt.All support elements 1 of the winding support are coupled at one end by connecting elements 4, one of which is arranged between two support elements 1. These connecting elements 4 are in essentially dimensionally stable. They each have a radially inwardly open opening 5, which is slightly larger than the dimensions of a support element 1 in the non-compressed position. It follows that the openings 5 advantageously also have a V-shaped design. The connecting elements 4 project radially outward beyond the envelope surface common to the supporting elements 1. They are connected at their radially inner circumferential edges 6 in a hinge-like manner to a respective support element 1, so that the position of the leg 2 of such a support element 1 relative to the associated connecting element 4 can be changed easily by compressing the support element 1.

Wie insbesondere aus Fig. 1 ersichtlich ist, sind die Tragelemente 1 neben den Verbindungselementen 4 noch-durch zwei ringartige Koppelelemente 7 verbunden. Diese Elemente setzen sich aus Ringsegmenten zusammen, die sich jeweils zwischen den einander zugewandten Schenkeln 2 benachbarter Tragelemente 1 erstrecken. Diese ringartigen Koppelelemente 7 liegen mit ihrer Innenfläche 8 im wesentlichen auf der gleichen Zylinderfläche wie die Innenflächen der Tragelemente 1, so daß ein ringartiges Koppelelement 7 als maximale Begrenzung für das Ineinanderschieben zweier gleichartiger Wickelträger Verwendung finden kann.As can be seen in particular from FIG. 1, in addition to the connecting elements 4, the support elements 1 are also connected by two ring-like coupling elements 7. These elements are composed of ring segments, each of which extends between the mutually facing legs 2 of adjacent support elements 1. These ring-like coupling elements 7 lie with their inner surface 8 essentially on the same cylindrical surface as the inner surfaces of the support elements 1, so that a ring-like coupling element 7 can be used as the maximum limit for the insertion of two identical winding carriers into one another.

Die Ausführungsform nach Fig. 1 sieht darüber hinaus noch ein weiteres ringartiges Koppelelement 9 vor, das im Bereich des von den Verbindungselementen 4 entfernt liegenden Endes des Wickelträgers angeordnet ist und eine zusätzliche Aussteifung bewirkt. Auch dieses Koppelelement 9 setzt. sich aus Ringsegmenten zusammen, wobei diese aber so angeordnet sind, daß der Außendurchmesser dieses Koppelelements 9 gleich oder kleiner ist als der Durchmesser der Zylinderfläche, auf der die Innenflächen der Tragelemente 1 liegen. Im Bereich oes Koppelelements 9 haben die radial außenliegenden Enden eine Abschrägung 10'.The embodiment according to FIG. 1 also provides a further ring-like coupling element 9, which is arranged in the region of the end of the winding carrier that is remote from the connecting elements 4 and causes additional stiffening. This coupling element 9 also sets. are composed of ring segments, but these are arranged such that the outer diameter of this coupling element 9 is equal to or smaller than the diameter of the cylinder surface on which the inner surfaces of the support elements 1 lie. In the area of the coupling element 9, the radially outer ends have a bevel 10 '.

Zwei axial fluchtende Wickelträger gemäß der Ausführungsform nach den Fig. 1 und 2 können zum Teil ineinandergeschoben werden, indem nämlich die Tragelemente 1 des Wickelträgers in die Durchbrüche 5 der Verbindungselemente 4 eines anderen Wickelträgers eingeführt werden. Der eine Wickelträger kann dann soweit in den anderen eingeschoben werden, bis die vorderen Enden der Tragelemente 1 auf eine Begrenzung, insbesondere ein Koppelelement 7 stoßen.Two axially aligned winding carriers according to the embodiment according to FIGS. 1 and 2 can be partially pushed into one another, namely by inserting the support elements 1 of the winding carrier into the openings 5 of the connecting elements 4 of another winding carrier. One winding carrier can then be inserted into the other until the meet the front ends of the support elements 1 on a boundary, in particular a coupling element 7.

Wird nun ein radial wirksamer Druck auf den Wickelträger ausgeübt, so werden die Schenkel 2 jedes Tragelements 1 in Richtung aufeinanderzu gedrückt. Die verschiedenen Verbindungs- und Koppelelemente nehmen an dieser Verformung nicht teil. Diese Verformung beeinträchtigt im übrigen auch nicht die relative axiale Verschiebbarkeit zwischen zwei Wickelträgern.If a radially effective pressure is now exerted on the winding support, the legs 2 of each support element 1 are pressed towards one another. The various connecting and coupling elements do not take part in this deformation. This deformation also does not affect the relative axial displaceability between two winding carriers.

Auch die Ausführungsform des erfindungsgemäßen Wickelträgers nach den Fig. 3 und 4 weist Tragelemente 1 mit jeweils zwei Schenkeln 2 auf, wie dies in Verbindung mit der Ausführungsform nach Fig. 1 und 2 beschrieben wurde. Dabei sind aber alle Tragelemente des Wickelträgers nach seinem einen Ende durch im wesentlichen formstabile Verbindungselemente 10 gekoppelt, von denen jeweils eines zwischen zwei Tragelementen 1 eingeordnet ist. Diese Verbindungselemente 10 haben ebenso wie die Verbindungselemente 4 der Ausführungsform nach den Fig. 1 und 2 einen Durchbruch 5, der geringfügig größer ist, als es den Abmessungen eines Tragelementes 1 in nicht zusammengedrückter Stellung entspricht.The embodiment of the winding carrier according to the invention according to FIGS. 3 and 4 also has support elements 1 with two legs 2 each, as was described in connection with the embodiment according to FIGS. 1 and 2. In this case, however, all of the support elements of the winding support are coupled after its one end by substantially dimensionally stable connecting elements 10, one of which is arranged between two support elements 1. These connecting elements 10, like the connecting elements 4 of the embodiment according to FIGS. 1 and 2, have an opening 5 which is slightly larger than the dimensions of a supporting element 1 in the non-compressed position.

Die Verbindungselemente 10 weichen von denen der zuvor beschriebenen Ausführungsform lediglich dadurch ab, daß sie jeweils einen radial außenliegenden Abschnitt 11 aufweisen, der eine kreisbogenförmig ausgebildete Außenfläche 12 hat. Diese Außenflächen 12 der Verbindungselemente 10 liegen auf einer gemeinsamen Zylinderfläche, deren Achse derjenigen des Wickelträgers entspricht. Wie insbesondere Fig. 3, rechte Seite, zeigt, bildet jedes Verbindungselement 10 im Bereich seines Abschnitts 11 in Umfangsrichtung an seinem einen Ende einen Vorsprung 13 und an seinem anderen Ende einen zum Vorsprung 13 versetzten Vorsprung 14. Diese Vorsprünge 13, 14 eines Verbindungselementes 10 arbeiten mit entsprechend ausgebildeten Vorsprüngen 13, 14 der benachbarten Verbindungselemente zusammen, wobei sich dann die Vorsprünge 13, 14 benachbarter Verbindungselemente 10 übergreifen. Auf diese Weise bilden die Verbindungselemente 10 in ihrer Gesamtheit eine kontinuierliche Zylinderfläche, über die der Antrieb des Wickelträgers erfolgen kann. Durch das Übergreifen der Vorsprünge 13, 14 benachbarter Verbindungselemente 10 wird eine kontunierliche Anlauffläche auch beim radialen Zusammendrücken des Wickelträgers aufrechterhalten.The connecting elements 10 differ from those of the previously described embodiment only in that they each have a radially outer section 11 which has an arcuate outer surface 12. These outer surfaces 12 of the connecting elements 10 lie on a common cylindrical surface, the axis of which corresponds to that of the winding support. As shown in FIG. 3, right side, in particular, each connecting element 10 forms in the area of its section 11 in the circumferential direction at its one end a projection 13 and at its other end a projection 14 offset from the projection 13. These projections 13, 14 of a connecting element 10 work together with appropriately designed projections 13, 14 of the adjacent connecting elements, in which case the projections 13, 14 of adjacent connecting elements 10 overlap. In this way, the connecting elements 10 in their entirety form a continuous cylindrical surface over which the winding support can be driven. By overlapping the projections 13, 14 of adjacent connecting elements 10 a continuous contact surface is maintained even when the winding carrier is compressed radially.

Der Wickelträger nach den Fig. 3 und 4 weist ein ringartiges Koppelelement 15 auf, das aus Ringsegmenten zusammengesetzt ist, die sich jeweils zwischen den Schenkeln 2 benachbarter Tragelemente 1 erstrecken.3 and 4 has a ring-like coupling element 15 which is composed of ring segments which each extend between the legs 2 of adjacent support elements 1.

Schließlich ist im Bereich des von den Verbindungselementen 10 entfernt liegenden Endes des Wickelträgers ein weiteres Koppelelement 16 vorgesehen, das, wie in Verbindung mit den Fig. 1 und 2 bereits beschrieben, aus Ringsegmenten zusammengesetzt ist. An jedem Ringsegment des Koppelelements 16 ist ein Rand 17 eines V-förmig profilierten Knickelements 18 befestigt, dessen anderer Rand 19 an einem zentralen Führungsring 20 befestigt ist, der konzentrisch zur Achse des Wickelträgers sowie zu dem Koppelelement 16 verläuft. Der Führungsring 20 dient einer exakten Führung des gesamten Wickelträgers und auch einer Abstützung der Segmente des Koppelelements 16.Finally, a further coupling element 16 is provided in the region of the end of the winding carrier which is remote from the connecting elements 10 and, as already described in connection with FIGS. 1 and 2, is composed of ring segments. On each ring segment of the coupling element 16, an edge 17 of a V-shaped kink element 18 is fastened, the other edge 19 of which is fastened to a central guide ring 20 which runs concentrically to the axis of the winding carrier and to the coupling element 16. The guide ring 20 serves for exact guidance of the entire winding support and also for supporting the segments of the coupling element 16.

Wird nun ein radial wirksamer Druck auf diesen Wickelträger ausgeübt, so werden die Schenkel 2 jedes Tragelements 1 in Richtung aufeinanderzu gedrückt. Die einander benachbarten Verbindungselemente 10 verlagern sich relativ zueinander, wobei die Vorsprünge 13, 14 dieser Verbindungselemente 10 sich gegeneinander verschieben und dabei eine kontinuierliche Abrollfläche aufrechterhalten. Gleichzeitig werden die Knickelemente 18 in radialer Richtung zusammengedrückt. Die Koppelelemente 15 und 16 verändern bei dieser Verformung des gesamten Wickelträgers ihre Form nicht.If a radially effective pressure is now exerted on this winding support, the legs 2 of each support element 1 are pressed towards one another. The connecting elements 10 which are adjacent to one another are displaced relative to one another, the projections 13, 14 of these connecting elements 10 shifting relative to one another and thereby maintaining a continuous rolling surface. At the same time, the buckling elements 18 are compressed in the radial direction. The coupling elements 15 and 16 do not change their shape during this deformation of the entire winding support.

Die Ausführungsform nach den Fig. 5 und 6 weist eine Reihe von parallel zu der Achse des Wickelträgers verlaufenden Tragelementen 25 auf, die jeweils aus zwei parallel zueinander verlaufenden stegartigen Schenkeln 26 gebildet sind. An den beiden Enden des Wickelträgers sind die beiden Schenkel 26 eines Tragelementes 25 miteinander fest verbunden.The embodiment according to FIGS. 5 and 6 has a series of supporting elements 25 running parallel to the axis of the winding support, which are each formed from two web-like legs 26 running parallel to one another. At the two ends of the winding support, the two legs 26 of a support element 25 are firmly connected to one another.

Wie insbesondere aus Fig. 5 ersichtlich ist, sind die Tragelemente 25 an ihren beiden Enden sowohl radial innen als auch radial außen mit Abschrägungen 27, 28 versehen.As can be seen in particular from FIG. 5, the support elements 25 are provided with bevels 27, 28 at their two ends both radially on the inside and radially on the outside.

Bei dieser Ausführungsform ist vorzugsweise im Bereich der Längsmitte des Wickelträgers ein ringartiges Stützelement 29 vorgesehen, welches sich aus einer Reihe von Ringsegmenten zusammensetzt, die jeweils zwei Schenkel 26 von benachbarten Tragelementen 25 verbinden. Die radiale Erstrekkung der Ringsegmente entspricht im wesentlichen derjenigen der Schenkel 26. Der Wickelträger nach dieser Ausführungsform weist ferner einige ringartige Koppelelemente 30, 31, 32 und 33 auf.In this embodiment, a ring-like support element 29 is preferably provided in the region of the longitudinal center of the winding carrier, which is composed of a series of ring segments, each of which connects two legs 26 of adjacent support elements 25. The radial extent of the ring segments essentially corresponds to that of the legs 26. The winding support according to this embodiment also has some ring-like coupling elements 30, 31, 32 and 33.

Diese Elemente setzen sich ebenfalls aus Segmenten zusammen, die je zwei einander zugekehrte Schenkel 26 benachbarter Tragelemente 25 verbinden. Stützelement 29 und die Koppelelemente 30 bis 33 sorgen für die erforderliche Aussteifung des Wickelträgers.These elements are also composed of segments that connect two mutually facing legs 26 of adjacent support elements 25. Support element 29 and the coupling elements 30 to 33 ensure the required stiffening of the winding support.

Die Tragelemente 25 weisen in beiden Endbereichen des Wickelträgers, die über das dem jeweiligen Ende benachbarten Koppelelement 32, 33 hinausreichen, Innenflächen 35 auf, die auf einer Zylinderfläche liegen, deren Durchmesser gleich oder größer ist als der Außendurchmesser der Koppelelemente 30 bis 33 bezogen auf die Achse des Wickelträgers. Zwei Wickelträger gemäß dieser Ausführungsform der Erfindung können daher nach axialer Ausrichtung ebenfalls teilweise ineinandergeschoben werden, wobei die Tragelemente 25 des einen Wickelträgers zwischen den Tragelementen eines anderen Wickelträgers zu liegen kommen. Dabei übergreifen dann die freien Enden der Wickelträger jeweils die diesen Enden am engsten benachbarten Koppelelemente 32, 33.The support elements 25 have in both end regions of the winding support, which extend beyond the coupling element 32, 33 adjacent to the respective end, on inner surfaces 35 which lie on a cylindrical surface whose diameter is equal to or larger than the outer diameter of the coupling elements 30 to 33 in relation to the Axis of the winding carrier. Two winding carriers according to this embodiment of the invention can therefore also be partially pushed into one another after axial alignment, the supporting elements 25 of one winding carrier coming to lie between the supporting elements of another winding carrier. The free ends of the winding carriers then overlap the coupling elements 32, 33 that are closest to these ends.

Die dem jeweiligen Ende des Wickelträgers benachbarten Koppelelemente 32, 33 weisen an der dem Ende des Wickelträgers zugewandten Fläche Distanznocken 36 auf. Diese Distanznocken 36 bewirken, daß beim Ineinanderführen zweier Wickelträger zwischen den dann benachbarten Koppelelementen zweier Wickelträger ein Raum für den Durchtritt von Färbeflotte verbleibt und daß nicht zwei ebene Flächen aufeinander zu liegen kommen, die ein Trennen dieser Wickelträger erschweren könnten.The coupling elements 32, 33 adjacent to the respective end of the winding support have spacing cams 36 on the surface facing the end of the winding support. These spacer cams 36 have the effect that when two winding carriers are brought into one another, a space for the passage of dye liquor remains between the then adjacent coupling elements of two winding carriers and that two flat surfaces do not come to lie on one another, which could make it difficult to separate these winding carriers.

Wenn auf diesen Wickelträger ein radial wirksamer Druck ausgeübt wird, dann werden die Schenkel 26 jedes Tragelementes 25 aufeinanderzu verlagert, wodurch sich eine Verkürzung des Umfangs und damit eine Durchmesserreduzierung ergibt. Auch bei dieser Ausführungsform ist die relative Verschiebbarkeit zweier ineinandergreifender Wickelträger unabhängig von einer etwaigen radialen Zusammendrückung.If a radially effective pressure is exerted on this winding support, then the legs 26 of each support element 25 are displaced towards one another, which results in a shortening of the circumference and thus a diameter reduction results. In this embodiment, too, the relative displaceability of two intermeshing winding carriers is independent of any radial compression.

Es wird nun anhand der Fig. 7 und 8 eine weitere Ausführungsform des erfindungsgemäßen Wickelträgers beschrieben, welche eine Reihe von parallel zu der Achse des Wickelträgers verlaufenden Tragelementen 40 aufweist, die jeweils aus zwei parallel zueinander verlaufenden stegartigen Schenkeln 41 gebildet sind. An den beiden Enden des Wickelträgers sind die beiden Schenkel 41 eines Tragelements 40 V-förmig miteinander fest verbunden, wobei die Endbereiche jedes Tragelements 40 sich verjüngen. Zwischen den Schenkeln 41 jedes Tragelements 40 ist eine Reihe von Knickelementen 42 angeordnet, welche V-förmig ausgebildet sind und die beiden Schenkel 41 gegeneinander abstützen. In der dargestellten Ausführungsform sind vier derartige Knickelemente 42 vorgesehen, die in die allen Außenflächen der Tragelemente 40 gemeinsame Zylinderfläche hineinragen. Die Zahl sowie auch die Ausbildung dieser Knickelemente kann aber den jeweiligen Anforderungen angepaßt werden.A further embodiment of the winding support according to the invention will now be described with reference to FIGS. 7 and 8, which has a series of supporting elements 40 running parallel to the axis of the winding support, each of which is formed from two web-like legs 41 running parallel to one another. At the two ends of the winding support, the two legs 41 of a support element 40 are firmly connected to one another in a V-shape, the end regions of each support element 40 tapering. Between the legs 41 of each support element 40, a series of kink elements 42 is arranged, which are V-shaped and support the two legs 41 against each other. In the illustrated embodiment, four such folding elements 42 are provided, which protrude into the cylinder surface common to all outer surfaces of the support elements 40. The number and also the formation of these articulated elements can, however, be adapted to the respective requirements.

Auch diese Ausführungsform weist vorzugsweise im Bereich der Längsmitte des Wickelträgers ein ringartiges Stützelement 43 auf, das eine im Querschnitt im wesentlichen rechteckige Basis 44 sowie einen mittig davon ausgehenden, radial nach außen vorstehenden Steg 45 hat, der in die allen Außenflächen der Tragelemente 40 gemeinsame Zylinderfläche hineinragt. Auch dieses Stützelement 43 erstreckt sich jeweils nur zwischen den einander zugewandten Schenkeln 41 benachbarter Tragelemente 40.This embodiment also preferably has, in the region of the longitudinal center of the winding support, a ring-like support element 43 which has a base 44 which is essentially rectangular in cross section and a web 45 which projects radially outwards from the center and which has a cylinder surface common to all the outer surfaces of the support elements 40 protrudes. This support element 43 also extends only between the mutually facing legs 41 of adjacent support elements 40.

Bei dieser Ausführungsform wird durch die Stege 45 des Stützelements 43, die Schenkel 41 und die Knickelemente 42 eine kontinuierliche zylindrische Abrollfläche für ein walzenförmiges Antriebselement gebildet.In this embodiment, the webs 45 of the support element 43, the legs 41 and the buckling elements 42 form a continuous cylindrical rolling surface for a roller-shaped drive element.

Konzentrisch zu dem ringartigen Stützelement 43 ist radial innerhalb desselben ein Führungsring 46 angeordnet, dessen axiale Erstreckung größer ist als diejenige der Basis 44 des Stützelementes 43. Wie Fig. 7 zeigt, sind sowohl das Stützelement 43 als auch der Führungsring 46 zu einer gemeinsamen, normal zur Achse des Wickelträgers verlaufenden Ebene symmetrisch ausgebildet.A guide ring 46, whose axial extent is greater than that of the base 44 of the support element 43, is arranged radially inside the latter, concentrically with the ring-like support element 43. Both the support element 43 and the guide ring 46 are formed symmetrically to a common plane running normal to the axis of the winding support.

Zwischen der Basis eines Segments des Stützelements 43 und der Außenfläche des Führungsrings 46 ist jeweils ein Knicksteg 47 angeordnet, der sich, in Richtung der Achse des Wickelträgers betrachtet (Fig. 8), V-förmig darstellt. Die Scheitelfläche dieses V-förmigen Knicksteges 47 verläuft im wesentlichen parallel zur Achse des Wickelträgers. Die axiale Erstreckung des Knickstegs 47 vergrößert sich radial nach innen hin, ausgehend von der Basis 44 bis zur Außenfläche des Führungsrings 46.Between the base of a segment of the support element 43 and the outer surface of the guide ring 46 there is in each case a kink web 47 which, viewed in the direction of the axis of the winding carrier (FIG. 8), is V-shaped. The apex surface of this V-shaped buckling web 47 runs essentially parallel to the axis of the winding carrier. The axial extension of the buckling web 47 increases radially inwards, starting from the base 44 to the outer surface of the guide ring 46.

Beiderseits des Stützelements 43 sind mit Abstand dazu im Querschnitt T-förmig ausgebildete, ringförmige Koppelelemente 48, 49 vorgesehen, deren Innenflächen gemeinsam mit der Innenfläche der Basis 44 des Stützelements 43 auf einer gemeinsamen zylindrischen Fläche liegen.On both sides of the support element 43, annular coupling elements 48, 49 with a T-shaped cross section are provided at a distance therefrom, the inner surfaces of which lie together with the inner surface of the base 44 of the support element 43 on a common cylindrical surface.

Schließlich weist der Wickelträger nahe seinen Enden jeweils noch ein Koppelelement 50, 51 auf, welches einen rechteckigen Querschnitt hat. Auch diese beiden Koppelelemente 50, 51 liegen auf der gleichen Zylinderfläche wie die Innenflächen der Koppelelemente 48 und 49 sowie des Stützelementes 43. Dabei weisen die Koppelelemente 50, 51 an der dem Ende des Wickelträgers zugewandten Fläche Distanznocken 52 auf, die in Verbindung mit der Ausführungsform nach den Fig. 5 und 6 bereits beschrieben wurden. Die Tragelemente 40 zeigen in beiden Endbereichen des Wickelträgers, die über das dem jeweiligen Ende benachbarte Koppelelement 50, 51 hinausreichen, Innenflächen 53, die auf einer Zylinderfläche liegen, deren Durchmesser gleich oder größer als der Außendurchmesser der Koppelelemente 50, 51, bezogen auf die Achse des Wickelträgers ist. Somit können auch zwei Wickelträger dieser Ausführungsform der Erfindung nach axialer Ausrichtung teilweise ineinandergeschoben werden, wobei die Tragelemente 40 des einen Wickelträgers zwischen den Tragelementen eines anderen Wickelträgers zu liegen kommen. Dabei übergreifen dann die freien Enden der Wickelträger jeweils das diesem Ende am engsten benachbarte Koppelelement 50, 51. Wird auf diesen Wickelträger ein radial wirksamer Druck ausgeübt, dann werden die Schenkel 41 jedes Tragelements 40 aufeinanderzu verlagert, wodurch sich eine Verkürzung des Umfangs und damit eine Durchmesserreduzierung ergibt, so daß auf diese Weise der Durchmesser des Wickelträgers verkürzt wird. Bei diesem Zusammendrücken in radialer Richtung sind auch die zwischen Stützelement 43 und Führungsring 46 angeordneten Knickstege 47 zusammenzudrücken.Finally, the winding carrier has a coupling element 50, 51 near its ends, which has a rectangular cross section. These two coupling elements 50, 51 also lie on the same cylindrical surface as the inner surfaces of the coupling elements 48 and 49 and of the support element 43. The coupling elements 50, 51 have spacing cams 52 on the surface facing the end of the winding carrier, which are in connection with the embodiment 5 and 6 have already been described. The support elements 40 show in both end regions of the winding support, which extend beyond the coupling element 50, 51 adjacent to the respective end, inner surfaces 53, which lie on a cylindrical surface, the diameter of which is equal to or larger than the outer diameter of the coupling elements 50, 51, based on the axis of the winding carrier. Thus, two winding carriers of this embodiment of the invention can also be partially pushed into one another after axial alignment, the supporting elements 40 of one winding carrier coming to lie between the supporting elements of another winding carrier. The free ends of the winding carriers then overlap the coupling element 50, 51 which is closest to this end. If a radially effective pressure is exerted on this winding support, then the legs 41 of each support element 40 are displaced towards one another, which results in a shortening of the circumference and thus a reduction in diameter, so that the diameter of the winding support is shortened in this way. During this compression in the radial direction, the buckling webs 47 arranged between the support element 43 and the guide ring 46 are also to be compressed.

Bei allen beschriebenen Ausführungsformen kann ein nicht dargestellter Anlaufring auf den Wickelträger aufgesetzt werden, der aufgrund von radial nach innen offenen Nuten eine radial nach innen gerichtete Verlagerung der Tragelemente zuläßt und dabei eine kontinuierliche Abrollfläche beibehält. Ein solcher Anlaufring, der den größten Durchmesser des Wickelträgers übersteigen muß, ermöglicht den Antrieb des Wickelträgers durch einen walzenförmigen Rotationskörper, ergibt eine erhebliche Stabilisierung und fördert beträchtlich ein störungsfreies Abspulen, da dieser Ring jegliches Verhaken ausschließt.In all of the described embodiments, a thrust ring (not shown) can be placed on the winding support, which, due to the radially inwardly open grooves, permits a radially inward displacement of the support elements and thereby maintains a continuous rolling surface. Such a thrust ring, which must exceed the largest diameter of the winding carrier, enables the winding carrier to be driven by a roller-shaped rotating body, results in considerable stabilization and promotes trouble-free unwinding, since this ring prevents any jamming.

Die Wickelträger nach den beschriebenen Ausführungsformen werden zweckmäßigerweise aus Kunststoff gefertigt, können aber auch aus jedem anderen geeigneten Material hergestellt werden.The winding carriers according to the described embodiments are expediently made of plastic, but can also be made of any other suitable material.
