Description

Spule zum Aufwickeln von länglichem Gut Spool for winding elongated goods

Die Erfindung betrifft eine Spule zum Aufwickeln von länglichem Gut wie beispielsweise Kabel, Bandmaterial, Schnur o.dgl. aufwickel barem Gut.The invention relates to a spool for winding elongated material such as cables, tape material, cord or the like. wind up good.

In vielen industriellen Bereichen ist es erforderlich, zur Verarbeitung von läng- lichem Gut dieses auf Spulen aufzuwickeln. Derartige Spulen werden beispielsweise zum Transport und bei der Verlegung von Kabel, Bandmaterial o.dgl. aufwickelbarem Gut eingesetzt. Die Spulenkörper bestehen aus zwei Flanschen, die in Form von Scheiben ausgebildet sind. Zwischen diesen beiden Scheiben ist eine zylindrische Nabe angeordnet, deren zylindrische Außen- fläche die Wickelfläche bildet, auf der das längliche Gut aufwickelbar ist. Mittels einer Verbindungsvorrichtung (beispielsweise Verschraubung) sind die beiden Scheiben entweder untereinander oder aber jeweils mit der Nabe verbunden.In many industrial areas it is necessary to wind up elongated goods on spools. Such coils are used, for example, for transporting and laying cables, tape material or the like. windable good used. The coil formers consist of two flanges that are designed in the form of disks. A cylindrical hub is arranged between these two disks, the cylindrical outer surface of which forms the winding surface on which the elongated material can be wound. The two disks are connected either to one another or to the hub by means of a connecting device (for example screw connection).

Insbesondere zum Aufwickeln von Gut beträchtlicher Länge ist es erforderlich, dass die Spulenkörper recht großvolumig sind. Damit ist für den Transport vom Spulenhersteller zum Anwender der Spule und für die Vorhaltung sowie Lagerung der Spule beim Anwender ein nicht unerheblicher Platzbedarf erforderlich. Zur Reduktion des Platzbedarfs bietet es sich an, die Spule im auseinandergebauten Zustand zu transportieren und zu lagern. Während die beiden Scheiben als flache Körper bequem und platzsparend aufeinandergelegt werden können, benötigt man für die starre Nabe wiederum mehr Transport- und Lagervolumen.In particular for winding material of considerable length, it is necessary that the bobbins are of quite large volume. This means that a not inconsiderable amount of space is required for the transport from the coil manufacturer to the user of the coil and for the storage and storage of the coil by the user. To reduce the space requirement, it is advisable to transport and store the coil in the disassembled state. While the two disks can be conveniently placed on top of each other as flat bodies, they require more transport and storage volume for the rigid hub.

Der Erfindung liegt die Aufgabe zu Grunde, eine Spule zum Aufwickeln von länglichem Gut zu schaffen, die derart konstruiert ist, dass sie im zerlegten Zustand ein Minimum an Platzbedarf benötigt. Zur Lösung dieser Aufgabe wird mit der Erfindung eine Spule zum Aufwickeln von länglichem Gut, wie z.B. Kabel, Bandmaterial o.dgl. aufwickelbarem Gut vorgeschlagen, die versehen ist mit einem Spulenkörper, der eine erste Scheibe, eine zweite Scheibe, eine zwischen den beiden Scheiben angeordnete Nabe mit einer zylindrischen Außenfläche, auf die das längliche Gut aufwickelbar ist, und eine Verbindungsvorrichtung zum Verbinden der beiden Scheiben untereinander bei dazwischenliegender Nabe und/oder zum Verbinden jeder Scheibe mit der Nabe aufweist.The invention is based on the object of providing a spool for winding elongated material which is constructed in such a way that it requires a minimum of space in the disassembled state. To achieve this object, the invention uses a spool for winding elongated material, such as cables, tape material or the like. Windable good proposed, which is provided with a bobbin, the first disc, a second disc, a hub arranged between the two discs with a cylindrical outer surface on which the elongated material can be wound, and a connecting device for connecting the two discs together has intermediate hub and / or for connecting each disc to the hub.

Bei dieser Spule ist erfindungsgemäß vorgesehen, dass die Nabe aus einem elastisch verformbaren Materialstreifen gebildet ist, der in einem entspannten Zustand im wesentlichen flach und lang gestreckt ist und in eine im wesentlichen zylindrische Form bringbar ist, - wobei der Nabenmaterialstreifen an seinem einen in Längserstreckung angeordneten Ende mindestens ein erstes Verbindungselement (Hakenvorsprung) und an dem diesem Ende gegenüberliegenden Ende mindestens ein zweites Verbindungselement (Aussparung) aufweist, die zur Einnahme einer Zylinderform des Nabenmaterialstreifens miteinander verbindbar sind, und dass die Verbindungsvorrichtung lösbar ist.In this coil it is provided according to the invention that the hub is formed from an elastically deformable material strip, which in a relaxed state is essentially flat and elongated and can be brought into an essentially cylindrical shape, the hub material strip being arranged on its one in the longitudinal direction End has at least a first connecting element (hook projection) and at the end opposite this end at least a second connecting element (recess) which can be connected to each other to take a cylindrical shape of the hub material strip, and that the connecting device is detachable.

Die erfϊndungsgemäße Spule ist mit einer Nabe versehen, die durch Formung eines elastisch verformbaren flachen Materialstreifens zu einer Zylinderwand gebildet ist. Im entspannten Zustand (Abwicklung) ist der Materialstreifen flach und lang gestreckt. Mit Hilfe der Verbindungselement an den einander entgegengesetzten Enden in Längserstreckung des Materialstreifens lassen sich die Enden des Nabenmaterialstreifens nach dessen Verformung zu einem Zylinder miteinander verbinden. Die Verbindungselemente können vielfältig ausgebildet und sowohl integraler Bestandteil des Nabenmaterialstreifens als auch als separate Teile ausgebildet sein, die an den Enden des Nabenmaterialstreifens befestigt sind. Die Verbindungselemente sind insbesondere als Hakenvorsprünge und Aussparungen ausgebildet, wobei sich die Hakenvorsprünge zur Verbindung beider Enden des Nabenmaterialstreifens durch die ihnen zugeordneten Aussparungen erstrecken.The coil according to the invention is provided with a hub, which is formed by forming an elastically deformable flat material strip into a cylinder wall. In the relaxed state (processing), the material strip is flat and elongated. With the aid of the connecting element at the opposite ends in the longitudinal extension of the material strip, the ends of the hub material strip can be connected to one another after their deformation to form a cylinder. The connecting elements can be designed in a variety of ways, both as an integral part of the hub material strip and as separate parts which are fastened to the ends of the hub material strip. The connecting elements are in particular as Hook projections and recesses are formed, the hook projections for connecting both ends of the hub material strip extending through the recesses assigned to them.

Die in Längserstreckung angeordneten Enden des Materialstreifens überlappen einander im zur Zylinderwand geformten Zustand des Materialstreifens und über- bzw. untergreifen einander, wodurch die erforderlich Insichabstützung der Materialstreifenenden erzielbar ist, die verhindert, dass der elastische Materialstreifen bei Verbindung seiner Enden die Zylinderform beibehält. Dies ist wiederum vorteilhaft, was den Zusammenbau des Spulenkörpers betrifft. Würden die Enden des Materialstreifens über z.B. als Hakenvorsprünge und Aussparungen ausgebildete Verbindungselemente lediglich miteinander verbunden bleiben, ohne dass die Zylinderform selbsttätig aufrechterhalten bleibt,, so ist der Zusammenbau des Spulenkörpers etwas aufwendiger; denn manuell oder mittels Werkzeugen müsste dann die Nabe kurz vor der Montage des Spulenkörpers in eine zylindrische Form gebracht werden.The ends of the material strip arranged in the longitudinal extent overlap one another in the state of the material strip shaped to the cylinder wall and overlap or underlap one another, whereby the necessary internal support of the material strip ends can be achieved, which prevents the elastic material strip from maintaining the cylindrical shape when its ends are connected. This is again advantageous when it comes to assembling the bobbin. Would the ends of the strip of material be e.g. connecting elements designed as hook projections and recesses merely remain connected to one another without the cylinder shape being automatically maintained, so the assembly of the coil former is somewhat more complex; because the hub would then have to be brought into a cylindrical shape shortly before assembly of the coil former, either manually or by means of tools.

Im Falle von Hakenvorsprüngen und Aussparungen als Verbindungselemente erstrecken sich die Hakenvorsprünge durch die Aussparungen hindurch und übergreifen deren Begrenzungsrand. Beim Verbinden der Enden des Nabenmaterialstreifens werden zweckmäßigerweise die Hakenvorsprünge von (radial) außen in die Aussparungen eingeführt. Das die Hakenvorsprünge aufweisende Ende des Nabenmaterialstreifens liegt also außen an dem Naben- materialstreifenende mit den Aussparungen an. Der zwischen den Aussparun- gen und dem Querrand des Nabenmaterialstreifens gelegene Bereich dieses Endes liegt dann von innen an dem anderen Ende an und übt auf dieses andere Ende auf Grund der Rückstellfähigkeit des gebogenen Nabenmaterialstreifens eine radial nach außen gerichtete Kraft aus. Durch die Umgreifung der Aussparungsränder durch die Hakenvorsprünge ist eine dieser Kraft wider- stehende Anlageverbindung beider Enden gegeben, so dass die Zylinderform selbsttätig aufrechterhalten bleibt. Der Vorteil der erfindungsgemäßen Spule besteht darin, dass im zerlegten Zustand ausschließlich flache Teile existieren. Hierbei handelt es sich zum einen um die beiden Scheiben und zum anderen um den flachen Materialstreifen, der sich als Abwicklung der Zylinderwand der Nabe ergibt. Dieser elastische Materialstreifen ist in seinem entspannten Zustand flach bzw. allenfalls geringfügig gewölbt und kann problemlos in den flachen lang gestreckten Zustand überführt werden. Damit ist das Transport- und Lagervolumen ganz entscheidend reduziert, da nun auch die Nabe selbst im zerlegten Zustand wenig Platz benötigt.In the case of hook projections and recesses as connecting elements, the hook projections extend through the recesses and overlap their boundary edge. When connecting the ends of the hub material strip, the hook projections are expediently inserted into the recesses from (radially) outside. The end of the hub material strip which has the hook projections therefore lies on the outside against the end of the hub material strip with the cutouts. The area of this end located between the recesses and the transverse edge of the hub material strip then lies from the inside at the other end and exerts a radially outward force on this other end due to the resilience of the bent hub material strip. The grip of the recessed edges by the hook projections results in an abutment connection of both ends that resists this force, so that the cylinder shape is automatically maintained. The advantage of the coil according to the invention is that only flat parts exist in the disassembled state. These are the two disks on the one hand and the flat strip of material on the other, which results from the development of the cylinder wall of the hub. In its relaxed state, this elastic strip of material is flat or at most slightly arched and can easily be converted into the flat, elongated state. This significantly reduces the transport and storage volume, as the hub now takes up little space even when disassembled.

Es ist möglich, an dem einen in Längserstreckung des Materialstreifens angeordneten Ende ausschließlich Hakenvorsprünge und an dem anderen Ende ausschließlich Aussparungen vorzusehen. Alternativ dazu ist aber auch denk-, bar, Haken und Aufnahmevorsprünge an beiden Enden vorzusehen, wobei einem Hakenvorsprung des einen Endes eine Aussparung am anderen Ende und umgekehrt zugeordnet ist.It is possible to provide only hook projections on one end arranged in the longitudinal extent of the material strip and only recesses at the other end. As an alternative, however, it is also conceivable to provide hooks and receiving projections at both ends, a recess on the other end being assigned to a hook projection on one end and vice versa.

Die lösbare Verbindungsvorrichtung der erfindungsgemäßen Spule ist zweckmäßigerweise als eine Vielzahl von Spannbolzen ausgebildet, die sich von der einen Scheibe zur anderen Scheibe erstrecken und diese miteinander verspannen. Durch Anordnung der Nabe zwischen den beiden Scheiben wird die Nabe damit eingespannt gehalten.The releasable connecting device of the coil according to the invention is expediently designed as a multiplicity of tensioning bolts which extend from one disk to the other disk and brace them together. By arranging the hub between the two disks, the hub is thus held in place.

Eine Alternative zu Spannbolzen, die axial durch die Nabe und insbesondere gleichförmig verteilt innerhalb der Nabe angeordnet sind, kann auch eine die Drehachse des Spulenkörpers definierende Welle zwischen den beiden Scheiben vorgesehen werden, an deren Enden die Scheiben befestigt werden. Schließlich kann jede Scheibe auch für sich mit der Nabe verbunden sein.As an alternative to clamping bolts which are arranged axially through the hub and in particular uniformly distributed within the hub, a shaft defining the axis of rotation of the coil body can also be provided between the two disks, at the ends of which the disks are attached. Finally, each disc can also be connected to the hub by itself.

Zweckmäßigerweise sind die beiden Scheiben auf ihren im zusammengebauten Zustand einander zugewandten Innenseite mit Einrichtungen zur Aufnahme der Längsränder bzw. zur Anlage an den Längsrändern des Nabenmaterial- Streifens versehen. Diese Einrichtungen können beispielsweise als einzelne Vorsprünge oder als Ringvorsprünge oder aber auch als Ringnuten an den Innenseiten der Scheibe ausgebildet sein.The two disks are expediently provided on their inner side facing one another in the assembled state with devices for receiving the longitudinal edges or for contacting the longitudinal edges of the hub material. Stripe. These devices can be designed, for example, as individual projections or as ring projections or else as ring grooves on the inside of the disk.

In vorteilhafter Weiterbildung der Erfindung ist ferner vorgesehen, dass die beiden Scheiben jeweils zentral angeordnete Vorrichtung zur drehbaren Lagerung des Spulenkörpers aufweisen. Bei diesen Vorrichtungen handelt es sich im einfachsten Fall um zentrale Löcher, durch die sich hindurch eine Achse für die drehbare Lagerung des Spulenkörpers hindurchführen lässt, oder aber um nach außen abstehende Zapfen, Stutzen o.dgl. handeln, die von einem Drehlager einer separaten Vorrichtung aufgenommen werden, an der der Spulenkörper anbringbar ist.In an advantageous development of the invention, it is further provided that the two disks each have a centrally arranged device for rotatably supporting the coil former. In the simplest case, these devices are central holes through which an axis for the rotatable mounting of the coil former can be guided, or pins or stubs or the like projecting outwards. act, which are received by a rotary bearing of a separate device to which the bobbin can be attached.

Die Hakenvorsprünge und Aussparungen können unterschiedlich ausgestaltet sein und weisen vorzugsweise einander über- bzw. untergreifende Bereiche bzw. Randbereiche auf, die im zusammengebauten Zustand des Nabenmaterialstreifens aneinander liegen und damit verhindern, dass der Nabenmaterial- streifen infolge seiner Rückstellkraft von der Zylinderform, die er im zusammengebauten Zustand im wesentlichen aufweist, abweicht. Hierzu ist es erfor- derlich, dass die Querrandbereiche an beiden in Längserstreckung des Nabenmaterialstreifens angeordneten Enden zumindest bereichsweise jeweils radial innen an dem jeweils anderen Ende des Nabenmaterialstreifens anliegen, wenn dieser seine Zylinderform einnimmt. Mit anderen Worten müssen sich die beiden Enden des Nabenmaterialstreifens durchdringen können, so dass das bei der Formung des Nabenmaterialstreifens zur Zylinderwand radial außenliegende der beiden einander überlappenden Enden durch das radial innenliegende Ende hindurchgesteckt werden kann. Hier sind letztendlich eine Vielzahl von Ausgestaltungen für die Hakenvorsprünge und die Aussparungen denkbar.The hook projections and recesses can be configured differently and preferably have overlapping or underlapping areas or edge areas which lie against one another in the assembled state of the hub material strip and thus prevent the hub material strip from the cylinder shape which it is in as a result of its restoring force essentially assembled, deviates. For this purpose, it is necessary that the transverse edge areas at both ends arranged in the longitudinal extent of the hub material strip rest at least in regions radially on the inside at the other end of the hub material strip when the latter takes on its cylindrical shape. In other words, the two ends of the hub material strip must be able to penetrate one another, so that the two ends of the two overlapping ends which are radially outward when the hub material strip is formed into the cylinder wall can be pushed through the radially inner end. Ultimately, a large number of configurations for the hook projections and the cutouts are conceivable here.

Zusätzlich kann es zur Vermeidung von vorspringenden Teilen an den Enden des Nabenmaterialstreifens bei Einnahme von dessen Zylinderform zweckmäßig sein, wenn die Bereiche um die Aussparungen herum vertieft oder er- heben und/oder die Hakenvorsprünge gekröpft, abgewinkelt o.dgl. verlaufen. Auf diese Weise ist es möglich, der Nabe im Bereich der sich überlappenden Enden ihres Nabenmaterialstreifens eine Wandstärke zu verleihen, die im wesentlichen gleich der doppelten Dicke des Nabenmaterialstreifens ist.In addition, in order to avoid protruding parts at the ends of the hub material strip when taking its cylindrical shape, it can be expedient if the areas around the recesses are deepened or lift and / or the hook projections cranked, angled or the like. run. In this way it is possible to give the hub a wall thickness in the region of the overlapping ends of its hub material strip which is essentially equal to twice the thickness of the hub material strip.

Als Materialien für die erfindungsgemäße Spule eigenen sich insbesondere Kunststoffe und Metall. Dabei bestehen die beiden Scheiben zweckmäßigerweise aus Kunststoff, wobei sie vorzugsweise als Spritzgussteile hergestellt sind. Der Nabenmaterialstreifen besteht demgegenüber vorzugsweise aus Metall und liegt insbesondere als Blechstreifen vor. Dieser Blechstreifen besteht insbesondere aus Federstahl.Plastics and metal are particularly suitable as materials for the coil according to the invention. The two disks are expediently made of plastic, wherein they are preferably produced as injection molded parts. In contrast, the hub material strip is preferably made of metal and is present in particular as a sheet metal strip. This sheet metal strip consists in particular of spring steel.

In den Fign. 1 bis 5 ist ein erstes Ausführungsbeispiel einer Spule dargestellt. Gemäß den Fign. 1 und 2 weist der Spulenkörper 10 eine erste und eine zweite Scheibe 12,14 auf, die jeweils als Kunststoff-Spritzgussteile hergestellt sind und miteinander fluchtende zentrale Löcher 15 zur Aufnahme einer Drehachse zur drehbaren Lagerung des Spulenkörpers aufweisen. Zwischen den beiden die Flansche des Spulenkörpers 10 bildenden Scheiben 12 und 14 befindet sich als Spulenkern eine zylindrische Nabe 16 aus Federstahlblech. Die axialen Enden der Zylinderwand 18 der Nabe 16 sind in ringförmigen Nuten 20,22 aufgenommen, die in den einander zugewandten Innenseiten 24,26 der Scheiben 12,14 ausgebildet sind und konzentrisch um die Drehachse 28 des Spulenkörpers 10 verlaufen. Die Außenseite 30 der Nabe 16 bildet die Wickel- fläche, auf die längliches Gut wie beispielsweise Kabel oder Schlauchmaterial aufgewickelt werden kann. Insofern kann die Nabe 16 auch als Wickelkern oder Spulenkern aufgefasst werden. Der Spulenkörper 10 wird von mehreren Spannbolzen 31 zusammengehalten, die sich parallel zur Drehachse 28 innerhalb der Nabe 16 von der einen Scheibe 12 zur anderen Scheibe 14 er- strecken. Auf diese Weise werden die beiden Scheiben 12,14 mit der zwischen ihnen angeordneten Nabe 16 zusammengehalten. Durch Lösen der Spannbolzen 31 lässt sich der Spulenkörper 10 zerlegen.In Figs. 1 to 5, a first embodiment of a coil is shown. According to FIGS. 1 and 2, the coil former 10 has a first and a second disk 12, 14, which are each produced as plastic injection-molded parts and have central holes 15 aligned with one another for receiving an axis of rotation for rotatably mounting the coil former. Between the two disks 12 and 14 forming the flanges of the coil former 10, there is a cylindrical hub 16 made of spring steel sheet as the coil core. The axial ends of the cylinder wall 18 of the hub 16 are received in annular grooves 20, 22 which are formed in the mutually facing inner sides 24, 26 of the disks 12, 14 and run concentrically around the axis of rotation 28 of the coil former 10. The outside 30 of the hub 16 forms the winding surface onto which elongated material such as cables or hose material can be wound. In this respect, the hub 16 can also be understood as a winding core or coil core. The bobbin 10 is held together by a plurality of clamping bolts 31, which extend parallel to the axis of rotation 28 within the hub 16 from one disk 12 to the other disk 14. In this way, the two disks 12, 14 are held together with the hub 16 arranged between them. The bobbin 10 can be disassembled by loosening the clamping bolts 31.

Der Vorzug des hier beschriebenen Spulenkörpers 10 besteht darin, dass die Nabe 16 aus einem elastischen Materialstreifen, beispielsweise Blechstreifen aus Federstahl besteht, der an seinen Enden zur Formung einer die Nabe 16 bildenden Zylinderwand lösbar miteinander verbindbar ist. Ein erstes Ausfüh- rungsbeispiel eines solchen Materialstreifens 32 ist als Abwicklung in Draufsicht in Fig. 3 gezeigt.The advantage of the coil former 10 described here is that the hub 16 consists of an elastic strip of material, for example sheet metal strips made of spring steel, which can be detachably connected at its ends to form a cylinder wall forming the hub 16. A first execution Example of such a strip of material 32 is shown as a plan view development in Fig. 3.

Der Materialstreifen 32 weist zwei Längsränder 34 und zwei quer dazu verlau- fende Querränder 36,38 auf. Die Querränder 36 und 38 begrenzen die in Längserstreckung liegenden Enden 40,42 des Materialstreifens 32. Zum Verbinden der beiden Enden 40,42 weist das eine Ende 40 eine Vielzahl von von der einen Seite 44 aufragenden Hakenvorsprüngen 46 auf, die in Erstreckung des Querrandes 36 nebeneinanderliegend angeordnet sind. Diese Hakenvor- sprünge 46 übergreifen Aussparungen 48, die am Ende 40 des Materialstreifens 32 in diesen eingebracht sind. Die Ausbildung der Hakenvorsprünge 46 und der Aussparungen 48 erfolgt beispielsweise mittels eines Stanz- und Tiefziehwerkzeuges.The material strip 32 has two longitudinal edges 34 and two transverse edges 36, 38 running transversely thereto. The transverse edges 36 and 38 delimit the ends 40, 42 of the material strip 32 lying in the longitudinal extent. To connect the two ends 40, 42, the one end 40 has a multiplicity of hook projections 46 which protrude from one side 44 and which extend into the transverse edge 36 are arranged side by side. These hook projections 46 overlap recesses 48 which are introduced into the end of the material strip 32. The hook projections 46 and the recesses 48 are formed, for example, by means of a stamping and deep-drawing tool.

Am anderen Ende 42 des Materialstreifens 32 sind identische Hakenvorsprünge 50 ausgebildet, die Aussparungen 52 übergreifen, welche insbesondere zum Querrand 38 offen sind. Auch die Hakenvorsprünge 50 sind durch ein Stanz- und Tiefziehwerkzeug hergestellt, sind jedoch im Unterschied zu den Hakenvorsprüngen 46 des Endes 40 des Materialstreifens 32 auf der der Seite 44 gegenüberliegenden Seite 54 angeordnet. Die in den Fign. 3 und 4 gezeigte Konstruktion der Enden 40 und 42 des Materialstreifens 32 erlaubt ein Verbinden dieser beiden Enden, indem die Hakenvorsprünge 46 am Materialstreifenende 40 die Aussparungen 52 am Materialstreifenende 42 und die Hakenvorsprünge 50 am Ende 42 die Aussparungen 48 am Ende 40 durchdringen. Hierdurch kann der Materialstreifen 32 gemäß Fig. 5 als Zylinderwand geformt werden, die die Nabe 16 des Spulenkörpers 10 bildet.At the other end 42 of the material strip 32, identical hook projections 50 are formed which overlap recesses 52 which are open in particular to the transverse edge 38. The hook projections 50 are also produced by a stamping and deep-drawing tool, but, in contrast to the hook projections 46 of the end 40 of the material strip 32, are arranged on the side 54 opposite the side 44. The in Figs. The construction of the ends 40 and 42 of the material strip 32 shown in FIGS. 3 and 4 allows these two ends to be connected by the hook projections 46 at the material strip end 40 penetrating the cutouts 52 at the material strip end 42 and the hook projections 50 at the end 42 penetrating the cutouts 48 at the end 40. As a result, the material strip 32 according to FIG. 5 can be shaped as a cylinder wall which forms the hub 16 of the coil former 10.

In den Fign. 6 bis 8 ist ein zweites Ausführungsbeispiel eines Materialstreifens 32' gezeigt. So weit die einzelnen Bestandteile dieses Materialstreifens 32' denjenigen gemäß den Fign. 3 bis 5 entsprechen, sind sie mit den gleichen Bezugszeichen versehen. Der Unterschied der beiden Materialstreifen 32 und 32' besteht in der Ausbildung der Aussparungen 52 am Materialstreifenende 42 und der Hakenvorsprünge 46 am Materialstreifenende 40. Diese Hakenvorsprünge 46 sind nämlich bei dem Materialstreifen 32" derart angeordnet, dass sie in dessen Längs- erstreckung von dem Querrand 36 abstehen. Wie man anhand von Fig. 7 erkennen kann, stehen die Hakenvorsprünge 46 nach unten über die Seite 54 über. Jeder Hakenvorsprung 46 weist einen in der Ebene des Materialstreifens 32' angeordneten Längssteg 56 und einen dazu querverlaufenden Quersteg 58 auf, was den Hakenvorsprüngen 46 insgesamt die Form eines T verleiht. Die Querstege 58 sind im wesentlichen um die Dicke des Materialstreifens 32' zu dessen Seite 44 versetzt angeordnet. Auch die Aussparungen 52 sind T-förmig und weisen einen Längserstreckungsabschnitt 60 sowie einen quer dazu verlaufenden Quererstreckungsabschnitt 62 auf. Die Bereiche des Endes 42 des Materialstreifens 32', die an die Längs- und Quererstreckungsabschnitte 60,62 angrenzen, sind im wesentlichen um die Dicke des Materialstreifens 32' gegenüber der Seite 54 des Materialstreifens 32' versetzt, also erhaben angeordnet.In Figs. 6 to 8, a second exemplary embodiment of a material strip 32 'is shown. As far as the individual components of this material strip 32 'correspond to those according to FIGS. 3 to 5 correspond, they are provided with the same reference numerals. The difference between the two material strips 32 and 32 'consists in the formation of the cutouts 52 at the material strip end 42 and the hook projections 46 at the material strip end 40. These hook projections 46 are namely arranged in the material strip 32 "in such a way that they extend longitudinally from the transverse edge 7, the hook projections 46 protrude downward beyond the side 54. Each hook projection 46 has a longitudinal web 56 arranged in the plane of the material strip 32 'and a transverse web 58 running transversely thereto, which means that Overall, hook projections 46 give the shape of a T. The transverse webs 58 are essentially offset by the thickness of the material strip 32 'on its side 44. The recesses 52 are also T-shaped and have a longitudinal extension section 60 and a transverse extension section 62 running transversely thereto The areas of the end 42 of the strip of material 32 'that the longitudinal and transverse extension sections 60, 62 adjoin are essentially offset by the thickness of the material strip 32 'relative to the side 54 of the material strip 32', that is to say they are arranged in a raised manner.

Zum Zusammenbauen des Materialstreifens 32' als Zylinderwand werden nun die Querstege 58 der Hakenvorsprünge 46 von der Seite 54 des Materia Istreifens 32' aus in die Quererstreckungsabschnitte 62 der Aussparungen 52 eingeführt, so dass sie anschließend von der Seite 44 aus, die nunmehr die Innenseite der Zylinderwand bildet, am Ende 42 des Materialstreifens 32' anliegen. Die Längsstege 56 erstrecken sich dabei von der Seite 44 zur Seite 54 des Materialstreifens 32' durch die Längserstreckungsabschnitte 60 der Aussparungen 52 hindurch. Auf diese Weise findet eine Durchdringung beider Enden 40 und 42 des Materialstreifens 32' mit Überlappung und gegenseitiger Abstützung der Enden 40,42 statt, was wie im Ausführungsbeispiel gemäß den Fign. 3 bis 5 dafür sorgt, dass die bei umgebogenem Materialstreifen 32 bzw. 32' erzeugte Rückstell kraft zur Aufrechterhaltung der zylindrischen Form gemäß den Fign. 5 und 8 ausgenutzt wird. Die Fign. 9 bis 12 verdeutlichen die unterschiedlichen Phasen des Zusammenbaus der Nabe 16 aus dem Nabenmaterialstreifen 32' und insbesondere die Art und Weise des Einführens der Hakenvorsprünge 46 in die Aussparungen 52 und deren gegenseitige Verhakung.To assemble the material strip 32 'as a cylinder wall, the transverse webs 58 of the hook projections 46 are now inserted from the side 54 of the material tire 32' into the transverse extension sections 62 of the recesses 52, so that they then from the side 44, which is now the inside of the Cylinder wall forms, rest against the end 42 of the material strip 32 '. The longitudinal webs 56 extend from the side 44 to the side 54 of the material strip 32 ′ through the longitudinal extension sections 60 of the cutouts 52. In this way, a penetration of both ends 40 and 42 of the material strip 32 'takes place with overlap and mutual support of the ends 40, 42, which, as in the exemplary embodiment according to FIGS. 3 to 5 ensures that the restoring force generated when the material strip 32 or 32 'is bent over to maintain the cylindrical shape according to FIGS. 5 and 8 is used. The figures 9 to 12 illustrate the different phases of the assembly of the hub 16 from the hub material strip 32 'and in particular the manner in which the hook projections 46 are inserted into the recesses 52 and their mutual interlocking.

Es versteht sich von selbst, dass die Hakenvorsprünge 46 auch geradlinig, d.h. ohne Kröpfung von dem Nabenmaterialstreifen 32' abstehen können und dieser an seinem anderen Ende in Höhe der Aussparungen 52 eine Stufung (Sickenausbildung) aufweist, so dass sich insgesamt eine zur Ausgestaltung gemäß den Fign. 5 bis 12 komplementäre Formgebung der Enden des Nabenmaterialstreifens 32' ergibt.It goes without saying that the hook projections 46 are also straight, i.e. can protrude from the hub material strip 32 'without cranking and the latter has a step (bead formation) at its other end at the level of the recesses 52, so that overall one configuration for the configuration according to FIGS. 5 to 12 gives complementary shaping of the ends of the hub material strip 32 '.

Durch die spezielle Ausgestaltung der Nabe 16 als ein zu einer Zylinderwand, geformter Materialstreifen lässt sich der gesamte Spulenkörper 10 vollständig zerlegen, wobei jeder Teil und insbesondere die Nabe 16 lediglich den durch das Materialvolumen des Materialstreifens definierten Platzbedarf benötigt. Damit lässt sich der Spulenkörper 10 platzsparend zusammenlegen, was im Hinblick auf sowohl den Transport als auch die Lagerung des Spulenkörpers 10 von Vorteil ist. Due to the special design of the hub 16 as a material strip shaped into a cylinder wall, the entire coil body 10 can be completely disassembled, with each part and in particular the hub 16 only requiring the space required defined by the material volume of the material strip. The bobbin 10 can thus be folded together to save space, which is advantageous with regard to both the transport and the storage of the bobbin 10.
