Definitions

  • the invention relates to a winding carrier, which can be partially inserted in the axial direction into a winding carrier of the same design, with supporting elements running parallel to its axis and connected to one another via essentially dimensionally stable coupling pieces, which project radially outward into a common cylindrical surface and form a winding surface, whereby the distance between two adjacent support elements is greater than the dimension of a support element in the circumferential direction, the maximum outer diameter of the coupling pieces in one end region of the winding support being equal to or smaller than the diameter of the cylinder surface on which the inner surfaces of the support elements in the other end region of the winding support lie, while at the other end a radially outwardly projecting flange is provided over the support elements, to which the support elements are connected and which has openings which are open radially inwards and which accommodate the support elements of a slidable winding carrier serve.

Description

Die Erfindung betrifft einen Wickelträger, der in axialer Richtung teilweise in einen gleich ausgebildeten Wickelträger einschiebbar ist, mit parallel zu seiner Achse verlaufenden, miteinander über im wesentlichen formstabile Koppelstücke verbundenen Tragelementen, die radial nach außen in eine gemeinsame Zylinderfläche hineinragen und eine Wickelfläche bilden, wobei der Abstand zwischen zwei benachbarten Tragelementen größer ist als es der Abmessung eines Tragelements in Umfangsrichtung entspricht, wobei in einem Endbereich des Wickelträgers der maximale Außendurchmesser der Koppelstücke gleich oder kleiner ist als der Durchmesser der Zylinderfläche, auf der die Innenflächen der Tragelemente im anderen Endbereich des Wickelträgers liegen, während am anderen Endbereich ein radial nach außen über die Tragelemente vorstehender Flansch vorgesehen ist, an den die Tragelemente angeschlossen sind und der radial nach innen offene Durchbrüche aufweist, die zur Aufnahme der Tragelemente des einzuschiebenden Wickelträgers dienen.The invention relates to a winding carrier, which can be partially inserted in the axial direction into a winding carrier of the same design, with supporting elements running parallel to its axis and connected to one another via essentially dimensionally stable coupling pieces, which project radially outward into a common cylindrical surface and form a winding surface, whereby the distance between two adjacent support elements is greater than the dimension of a support element in the circumferential direction, the maximum outer diameter of the coupling pieces in one end region of the winding support being equal to or smaller than the diameter of the cylinder surface on which the inner surfaces of the support elements in the other end region of the winding support lie, while at the other end a radially outwardly projecting flange is provided over the support elements, to which the support elements are connected and which has openings which are open radially inwards and which accommodate the support elements of a slidable winding carrier serve.

Bei einem bekannten Wickelträger dieser Art für Faden- und Garnwickel (FR-A 2 289 423) sind die Tragelemente stabförmig ausgebildet und an ihrem einem Ende durch einen formstabilen ringförmigen Flansch gekoppelt.In a known winding support of this type for thread and yarn winding (FR-A 2 289 423), the support elements are rod-shaped and are coupled at one end by a dimensionally stable annular flange.

Dieser Wickelträger macht es möglich, zum Teil in einen gleich ausgebildeten Wickelträger in axialer Richtung eingeschoben zu werden. Es ist damit also möglich, die axiale Ausgangslänge mehrerer übereinandergesetzter Wickelträger durch Zusammendrücken und Ineinandergreifen zu verkürzen. Der Durchmesser dieses Wickelträgers ist im wesentlichen starr. Er kann also einem Schrumpfen der Garnwickel durch Nachgeben in radialer Richtung nicht folgen.This winding carrier makes it possible to be partially inserted into an identical winding carrier in the axial direction. It is thus possible to shorten the axial starting length of several winding carriers placed one above the other by compressing and intermeshing. The diameter of this winding carrier is essentially rigid. He can not follow a shrinkage of the yarn package by giving in the radial direction.

Ferner sind Wickelträger bekannt, die in radialer Richtung zusammendrückbar sind, aber ein axiales Zusammenschieben eines Wickelträgers in axialer Richtung in einen anderen nicht gestatten.Furthermore, winding carriers are known, which can be compressed in the radial direction, but do not allow an axial compression of one winding carrier in the axial direction into another.

Wickelträger dieser Gattung sind in den FR-A 2 168 682 und 2 290 381 offenbart. Sie haben formstabile Endringe an ihren beiden Enden, zwischen denen parallel zur Wickelträgerachse Tragelemente verlaufen, die im Querschnitt U-förmig sind, wobei die Schenkel ihres Profils radial nach innen weisen. Die in Umfangsrichtung benachbarten Schenkel von jeweils zwei solchen Tragelementen sind durch formstabile Koppelstücke miteinander verbunden. Die Tragelemente haben in den Bereichen ihrer Verbindung mit den Endringen ihren schwächsten Querschnitt. Das hat zur Folge, daß sich dann die Tragelemente mit Ausnahme ihrer Endringbereiche radial nach innen verlagern, wenn ein auf dem Wickelträger befindlicher Wickel eine entsprechende radial nach innen gerichtete Kraft ausübt. Bei dieser Verlagerung der Tragelemente werden die Schenkel jedes dieser Elemente aufeinanderzu gedrückt.Winding carriers of this type are disclosed in FR-A 2 168 682 and 2 290 381. They have dimensionally stable end rings at their two ends, between which support elements run parallel to the winding carrier axis and are U-shaped in cross section, the legs of their profile pointing radially inwards. The adjacent legs in the circumferential direction of two such support elements are connected to one another by dimensionally stable coupling pieces. The supporting elements have their weakest cross section in the areas of their connection to the end rings. The result of this is that the supporting elements, with the exception of their end ring regions, then move radially inward when a winding located on the winding support exerts a corresponding radially inward force. During this displacement of the support elements, the legs of each of these elements are pressed towards one another.

Weiter ist ein Wickelträger bekannt (US-A 3 563 490), bei dem die Tragelemente über in radialer Richtung nachgiebige Zwischenelemente auf einem Innenkörper abgestützt sind. Auch dieser Wickelträger gibt nicht die Möglichkeit, in einen gleich ausgebildeten Wickelträger teilweise axial eingesteckt zu werden. Ein axiales Zusammenpressen der darauf angeordneten Wickel ist folglich nicht möglich.Furthermore, a winding carrier is known (US-A 3 563 490), in which the support elements are supported on an inner body via intermediate elements which are flexible in the radial direction. This winding carrier also does not offer the possibility of being partially inserted axially into a winding carrier of the same design. Axial compression of the coils arranged thereon is consequently not possible.

Schließlich ist ein Wickelträger bekannt (FR-A 1 085 398), dessen Wickelfläche aus parallel zu seiner Achse verlaufenden Stäben gebildet ist, die an seinem einen Ende durch einen äußeren geschlitzten Ring verbunden sind. Nahe seinem anderen Ende verlaufen die Stäbe radial nach innen geneigt. Hier ist ein weiterer Ring vorgesehen, der ebenfalls einen Schlitz aufweist und auf dessen Außenrand die Stäbe aufliegen.Finally, a winding carrier is known (FR-A 1 085 398), the winding surface of which is formed from rods running parallel to its axis, which are connected at one end by an outer slotted ring. Near its other end, the bars are inclined radially inward. Here is another ring is provided, which also has a slot and the rods rest on the outer edge.

Bei diesem Wickelträger ist es möglich, das Ende mit den nach innen geneigten Stäben Jn das andere Ende eines benachbarten Wickelträgers eingreifen zu lassen. Das Ineinandergreifen erstreckt sich daher allein auf die Endbereiche der Wickelträger. Bei einem weiteren Zusammendrücken solcher Wickelträger ergeben sich aber aufgrund der Abstützung auf den nicht starren Endringen komplexe Schrägstellungen der Stäbe, die zu Verklemmungen führen können.With this winding support, it is possible to let the end with the inwardly inclined rods Jn engage the other end of an adjacent winding support. The intermeshing therefore extends only to the end regions of the winding carriers. When such winding carriers are further compressed, however, the support on the non-rigid end rings results in complex inclined positions of the rods, which can lead to jamming.

Die Aufgabe der vorliegenden Erfindung besteht demgegenüber darin, einen Wickelträger zu schaffen, der in Verbindung mit gleichartigen Wickelträgern ein störungsfreies Zusammendrücken der darauf befindlichen Faden- und Garnwickel in Achsrichtung sowie auch deren Schrumpfen in radialer Richtung gestattet, wobei beide Effekte nicht zwangsläufig gekoppelt sind. Dies soll bei einem einfachen Aufbau und damit bei problemloser Herstellbarkeit des Wickelträgers erreicht werden.In contrast, the object of the present invention is to provide a winding carrier which, in conjunction with similar winding carriers, permits trouble-free compression of the thread and yarn packages located thereon in the axial direction and also their shrinkage in the radial direction, the two effects not necessarily being coupled. This should be achieved with a simple structure and thus with ease of manufacture of the winding carrier.

Diese Aufgabe wird erfindungsgemäß bei einem Wickelträger der eingangs erwähnten Art dadurch gelöst, daß jedes Tragelement aus zwei in Umfangsrichtung aufeinanderzu zusammendrückbaren verbundenen Schenkeln gebildet ist, daß die Koppelstücke jeweils mit ihrem einen Ende mit dem freien Ende eines Schenkels eines Tragelements und mit ihrem anderen Ende mit dem freien Ende des demselben Koppelstück zugewandten Schenkels des in Umfangsrichtung benachbarten Tragelements verbunden sind, und daß der Flansch in im wesentlichen formstabile Flanschsegmente aufgeteilt ist, wobei jeweils ein Flanschsegment zwischen zwei benachbarte Tragelemente geschaltet ist und jeweils an seinen radial innen liegenden Enden mit einem Tragelement scharnierartig verbunden ist, wobei die Flanschsegmente so ausgebildet sind, daß sie ein Zusammendrücken des Flansches in Umfangsrichtung zulassen.This object is achieved in a winding carrier of the type mentioned above in that each support element is formed from two circumferentially compressible connected legs that the coupling pieces each with one end with the free end of a leg of a support element and with its other end with the free end of the leg facing the same coupling piece of the adjacent support element in the circumferential direction, and that the flange is divided into substantially dimensionally stable flange segments, one flange segment being connected between two adjacent support elements and each lying on its radially inner side Ends with a support element is connected in a hinge-like manner, the flange segments being designed such that they allow the flange to be compressed in the circumferential direction.

Mehrere Wickelträger dieser Art können bis zu dem jeweils gewünschten Maß ineinandergeschoben werden, um damit die axiale Länge der darauf befindlichen Faden- und Garnwickel zu reduzieren. Das axiale Zusammenschieben und das radiale Zusammendrücken stören sich gegenseitig in keiner Weise.Several bobbins of this type can be pushed into each other to the desired extent in order to reduce the axial length of the thread and yarn packages located thereon. The axial compression and the radial compression do not interfere with each other in any way.

Der erfindungsgemäße Wickelträger kann ferner so ausgebildet sein, daß benachbarte Flanschsegmente sich in Umfangsrichtung relativ zueinander verschiebbar überlappen.The winding carrier according to the invention can also be designed such that adjacent flange segments overlap relative to one another so as to be displaceable in the circumferential direction.

Daraus folgt, daß jeder Wickelträger unabhängig davon, ob bzw. wie weit er in radialer Richtung zusammengedrückt ist, eine kontinuierliche über die Wickelfläche radial nach außen vorstehende Abrollfläche ergibt, die mit einer Spultrommel ohne Schwierigkeiten zusammenarbeiten kann.It follows that, regardless of whether or how far it is compressed in the radial direction, each winding support results in a continuous rolling surface which projects radially outward beyond the winding surface and which can work together with a winding drum without difficulty.

Der erfindungsgemäße Wickelträger kann ferner so ausgebildet sein, daß die Koppelstücke als Ringsegmente ausgebildet sind. Daraus resultiert ein einfacher, stabiler Aufbau des Wickelträgers.The winding support according to the invention can also be designed so that the coupling pieces are designed as ring segments. This results in a simple, stable construction of the winding carrier.

Der erfindungsgemäße Wickelträger kann ferner so ausgebildet sein, daß die Koppelstücke mit nachgiebigen Knickelementen verbunden sind, die sich auf mindestens einem radial nach innen versetzt angeordneten starren Führungsring abstützen. Auf diese Weise wird einerseits eine sichere Führung des Wickelträgers auf dem jeweiligen Tragorgan und andererseits eine zuverlässige Abstützung der Tragelemente bewirkt.The winding support according to the invention can also be designed so that the coupling pieces are connected with flexible buckling elements which are supported on at least one rigid guide ring arranged radially inwards. In this way, secure guidance of the winding support on the respective support member is achieved, on the one hand, and reliable support of the support elements, on the other hand.

Im folgenden Teil der Beschreibung werden einige Ausführungsformen des erfindungsgemäßen Wickelträgers anhand von Zeichnungen beschrieben Es zeigt:

  • Fig. 4 eine Schnittansicht nach der Linie 4-4 in Fig. 3.
In the following part of the description, some embodiments of the winding support according to the invention are described with reference to drawings.
  • 1 is a partially sectioned view of a first embodiment of the winding support according to the invention along the line 1-1 in Fig. 2,
  • 2 is a sectional view taken along the line 2-2 in Fig. 1,
  • Fig. 3 is a partially sectioned view of a second embodiment of the winding support according to the invention along the line 3-3 in Fig. 4 and
  • 4 shows a sectional view along the line 4-4 in FIG. 3.

Die Ausführungsform des erfindungsgemäßen Wickelträgers nach den Fig. 1 und 2 weist parallel zur Achse des Wickelträgers verlaufende Tragelemente 1 auf. Jedes Tragelement 1 hat einen V-förmig ausgebildeten Querschnitt, der radial nach innen hin offen ist. Es ist somit von zwei Schenkeln 2 gebildet, die in Richtung aufeinanderzu zusammengedrückt werden können. Die Tragelemente 1 haben radial außenliegende Scheitelflächen 3, die auf einer gemeinsamen zylin- drischen 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 crest surfaces 3, on a common cylinder dri e n sch envelope surface.

Alle Tragelemente 1 des Wickelträgers sind an seinem einen Ende durch Flanschsegmente 4 gekoppelt, von denen jeweils eines zwischen zwei Tragelementen 1 angeordnet ist. Diese Flanschsegmente 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 sicht, daß die Durchbrüche 5 vorteilhaft ebenfalls eine V-förmige Ausbildung haben. Die Flanschsegmente 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 Flanschsegment 4 ohne weiteres durch Zusammendrücken des Tragelements 1 verändern läßt.All support elements 1 of the winding support are coupled at one end by flange segments 4, one of which is arranged between two support elements 1. These flange segments 4 are essentially dimensionally stable. They each have a radially inward opening 5 which is slightly larger than the dimensions of a support element 1 in the non-compressed position. This shows that the openings 5 advantageously also have a V-shaped design. The flange segments 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 flange segment 4 can be easily changed by compressing the support element 1.

Wie insbesondere aus Fig. 1 ersichtlich ist, sind die Tragelemente 1 neben den Flanschsegmenten 4 noch durch zwei ringartige Koppelstücke 7 verbunden. Diese Elemente setzen sich aus Ringsegmenten zusammen, die sich jeweils zwischen den einander zugewandten Schenkeln 2 benachbarter Tragelemente 1 erstrecken. Sie liegen mit ihrer Innenfläche 8 im wesentlichen auf der gleichen Zylinderfläche wie die Innenflächen der Tragelemente 1, so daß ein ringartiges Koppelstück 7 als maximale Begrenzung für das Ineinanderschieben zweier gleichartiger Wickelträger Verwendung finden kann.As can be seen in particular from FIG. 1, the support elements 1 are connected in addition to the flange segments 4 by two ring-like coupling pieces 7. These elements are composed of ring segments, each of which extends between the mutually facing legs 2 of adjacent support elements 1. They 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 piece 7 can be used as a maximum limitation for the insertion of two identical winding carriers.

Die Ausführungsform nach Fig. 1 sieht darüber hinaus noch ein weiteres ringartiges Koppelstück 9 vor, das im Bereich des von den Flanschsegmenten 4 entfernt liegenden Endes des Wickelträgers angeordnet ist und eine zusätzliche Aussteifung bewirkt. Auch dieses Koppelstück 9 setzt sich aus Ringsegmenten zusammen, wobei diese aber so angeordnet sind, daß der Außendurchmesser dieses Koppelstücks 9 gleich oder kleiner ist als der Durchmesser der Zylinderfläche, auf der die Innenflächen der Tragelemente 1 liegen. Im Bereich des Koppelstücks 9 haben die radial außenliegenden Enden der Tragelemente eine Abschrägung 10'.The embodiment according to FIG. 1 also provides a further ring-like coupling piece 9, which is arranged in the region of the end of the winding carrier that is remote from the flange segments 4 and causes additional stiffening. This coupling piece 9 is also composed of ring segments, but these are arranged such that the outer diameter of this coupling piece 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 piece 9, the radially outer ends of the support elements 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 Flanschsegmente 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 Koppelstück 7, stoßen.Two axially aligned winding carriers according to the embodiment according to FIGS. 1 and 2 can be partially pushed into each other, namely by inserting the support elements 1 of the winding carrier into the openings 5 of the flange segments 4 of another winding carrier. One winding support can then be pushed into the other until the front ends of the support elements 1 meet a boundary, in particular a coupling piece 7.

Wird nun ein radial wirksamer Druck auf den Wickelträger ausgeübt, so werden die Schenkel 2 jedes Tragelements 1 in Richtung aufeinanderzu gedrückt. Die Flanschsegmente sowie die Koppelstücke 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 flange segments as well as the Coupling pieces 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 nahe seinem einen Ende durch im wesentlichen formstabile Flanschsegmente 10 gekoppelt, von denen jeweils eines zwischen zwei Tragelementen 1 angeordnet ist. Diese Flanschsegmente 10 haben ebenso wie die Flanschsegmente 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 the support elements of the winding support are coupled near its one end by essentially dimensionally stable flange segments 10, one of which is arranged between two support elements 1. These flange segments 10, like the flange segments 4 of the embodiment according to FIGS. 1 and 2, have an opening 5 which is slightly larger than the dimensions of a support element 1 in the non-compressed position.

Die Flanschsegmente 10 weichen von denen der zuvor beschriebenen Ausführungsform lediglich dadurch ab, daß sie jeweils einen radial außen liegenden Abschnitt 11 aufweisen, der eine kreisbogenförmig ausgebildete Außenfläche 12 hat. Diese Außenflächen 12 der Flanschsegmente 10 liegen auf einer gemeinsamen Zylinderfläche, deren Achse derjenigen des Wickelträgers entspricht. Wie insbesondere Fig. 3 und 4, rechte Seite, zeigen, bildet jedes Flanschsegment 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 Flanschsegments 10 arbeiten mit entsprechend ausgebildeten Vorsprüngen 13, 14 des benachbarten Flanschsegments 10 zusammen, wobei sich dann die Vorsprünge 13, 14 benachbarter Flanschsegmente 10 übergreifen. Auf diese Weise bilden die Flanschsegmente 10 in ihrer Gesamtheit eine kontinuierliche Zylinderfläche, über die der Antrieb des Wickelträgers erfolgen kann. Durch das Übergreifen der Vorsprünge 13, 14 benachbarter Flanschsegmente 10 wird eine kontinuierliche Anlauffläche auch beim radialen Zusammendrücken des Wickelträgers aufrechterhalten.The flange segments 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 flange segments 10 lie on a common cylinder surface, the axis of which corresponds to that of the winding support. 3 and 4, right side, in particular, each flange segment 10 forms in the region 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 form one Flange segments 10 work together with correspondingly formed projections 13, 14 of the adjacent flange segment 10, the projections 13, 14 of adjacent flange segments 10 then overlapping. In this way, the flange segments 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 flange segments 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 Koppelstück 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 piece 15, which is composed of ring segments, each of which extends between the legs 2 of adjacent support elements 1.

Schließlich ist im Bereich des von den Flanschsegmenten 10 entfernt liegenden Endes des Wickelträgers eine weiteres Koppelstück 16 vorgesehen, das, wie in Verbindung mit den Fig. 1 und 2 bereits beschrieben, aus Ringsegmenten zusammengesetzt ist. An jedem Ringsegment des Koppelstücks 16 is 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 Koppelstück 16 verläuft. Der Führungsring 20 dient einer exakten Führung des gesamten Wickelträgers und auch einer Abstützung der Segmente des Koppelstücks 16.Finally, in the region of the end of the winding carrier which is remote from the flange segments 10, a further coupling piece 16 is provided which, as already described in connection with FIGS. 1 and 2, is composed of ring segments. On each ring segment of the coupling piece 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 piece 16. The guide ring 20 serves for exact guidance of the entire winding support and also for supporting the segments of the coupling piece 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 Flanschsegmente 10 verlagern sich relativ zueinander, wobei die Vorsprünge 13, 14 dieser Flanschsegmente 10 sich gegeneinander verschieben und dabei eine kontinuierliche Abrollfläche aufrechterhalten. Gleichzeitig werden die Knickelemente 18 in radialer Richtung zusammengedrückt. Die Koppelstücke 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 mutually adjacent flange segments 10 are displaced relative to one another, the projections 13, 14 of these flange segments 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 pieces 15 and 16 do not change their shape during this deformation of the entire winding support.

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 übersteigern 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 precludes any jamming.

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