Description

Die Erfindung bezieht sich auf eine Vorrichtung zur reversierenden Verseilung von Verseilelementen, bestehend aus einer feststehenden Führungsscheibe und aus einer mit Abstand zu derselben angeordneten, um ihre Achse drehbaren Verseilscheibe, die beide axial verlaufende Durchgangslöcher zur Durchführung der Verseilelemente aufweisen, sowie aus einem Festpunkt zur Fixierung der verseilten Verseilelemente im Verseilpunkt (DE-AS 22 62 705).The invention relates to a device for reversing stranding of stranding elements, consisting of a fixed guide washer and a spacer arranged around it, rotatable about its axis stranding disk, both of which have axially extending through holes for the passage of the stranding elements, and a fixed point for fixation the stranded stranding elements at the stranding point (DE-AS 22 62 705).

"Verseilelemente" im Sinne der Erfindung sind beispielsweise Adern von elektrischen und optischen Kabeln bzw. Leitungen aller Art. Verseilelemente können aber auch Bauteile höherer Ordnung sein, in denen schon mehrere Teile zusammengefaßt sind. Das sind beispielsweise Paare, Vierer oder Bündel. Bei den Verseilelementen kann es sich auch um Fäden aus Kunststoff oder um blanke metallische Drähte handeln, die beispielsweise für den konzentrischen Schutzleiter bei Starkstromkabeln eingesetzt werden."Stranding elements" in the sense of the invention are, for example, cores of electrical and optical cables or lines of all kinds. However, stranding elements can also be higher-order components in which several parts are already combined. These are, for example, pairs, quads or bundles. The stranding elements can also be threads made of plastic or bare metallic wires, which are used, for example, for the concentric protective conductor in power cables.

Die reversierende Verseilung, bei welcher die Schlagrichtung der Verseilelemente in Abständen wechselt, hat gegenüber dem Verseilverfahren mit gleichbleibender Schlagrichtung den Vorteil, daß keine rotierenden Spulenabläufe (Körbe) benötigt werden, die eine nur begrenzte Länge für das herzustellende Verseilgut zulassen. Die reversierende Verseilung bietet die Möglichkeit einer kontinuierlichen Fertigung mit hohen Abzugsgeschwindigkeiten.The reversing stranding, in which the direction of lay of the stranding elements changes at intervals, has the advantage over the stranding method with the same lay direction that no rotating spools (baskets) are required which allow only a limited length for the stranded material to be produced. The reversing stranding offers the possibility of continuous production with high take-off speeds.

Bei der bekannten Vorrichtung nach der eingangs beschriebenen DE-OS 22 62 705 werden die Verseilelemente zwischen der Führungsscheibe und der Verseilscheibe in Schläuchen geführt. Diese Schläuche bestehen aus einem Kunststoff mit niedrigem Reibungskoeffizienten. Sie sollen ein Verheddern der einzelnen Verseilelemente zwischen den beiden Scheiben verhindern. Vor Inbetriebnahme der Vorrichtung müssen die einzelnen Verseilelemente mit einigem Aufwand in die Schläuche eingefädelt werden. Die Schläuche können leicht verschmutzen, so daß sich gegenüber den Verseilelementen schlechtere Reibwerte ergeben. Sie haben außerdem eine relativ große Masse, die bei der Dimensionierung der Vorrichtung und insbesondere für den Antrieb der Verseilscheibe zu berücksichtigen ist. Weiterhin kann nicht ausgeschlossen werden, daß die Schläuche selbst miteinander verheddern, insbesondere dann, wenn der Abstand zwischen Führungsscheibe und Verseilscheibe groß ist.In the known device according to DE-OS 22 62 705 described at the outset, the stranding elements are guided in tubes between the guide washer and the stranding washer. These hoses are made of a plastic with a low coefficient of friction. They are intended to prevent the individual stranding elements from getting tangled between the two disks. Before the device is put into operation, the individual stranding elements have to be threaded into the hoses with some effort. The hoses can easily become dirty, so that there are poorer coefficients of friction compared to the stranding elements. They also have a relatively large mass, which must be taken into account when dimensioning the device and in particular for driving the stranding disk. Furthermore, it cannot be ruled out that the hoses themselves may become entangled, especially if the distance between the guide disk and the stranding disk is large.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Vorrichtung so weiterzubilden, daß bei einfachem Aufbau und einfacher Einrichtung derselben ein Verheddern der Verseilelemente mit Sicherheit vermieden ist.The invention has for its object to develop the device described above so that tangling of the stranding elements is avoided with a simple structure and simple setup of the same with certainty.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß zwischen Führungsscheibe und Verseilscheibe mindestens ein fadenförmiges, zugfestes Tragelement angeordnet ist, an dem mit Abstand zur Führungsscheibe einerseits und zur Verseilscheibe andererseits mindestens ein Halteelement angebracht ist, das in axialer Richtung verlaufende Durchgangslöcher zur Durchführung der Verseilelemente aufweist.This object is achieved according to the invention in that at least one thread-like, tensile support element is arranged between the guide disk and stranding disk, on which at least one holding element is attached at a distance from the guide disk on the one hand and to the stranding disk on the other hand, the through holes running in the axial direction for carrying out the stranding elements having.

Diese Vorrichtung ist sehr einfach aufgebaut. Sie besteht aus der Führungsscheibe und der Verseilscheibe und aus einer Anzahl von Halteelementen, die von der Länge des Abstands zwischen Führungs- und Verseilscheibe bestimmt wird. Beim Einrichten der Vorrichtung brauchen die Verseilelemente nur durch die Durchgangslöcher aller axial relativ kurzen Halteelemente gezogen zu werden. Die Halteelemente können aus einem Werkstoff mit niedrigem Reibungskoeffizienten hergestellt werden, so daß die Verseilelemente während der Fertigung einer verhältnismäßig geringen Reibung ausgesetzt sind. Die Halteelemente sind massearm, so daß selbst bei einer größeren Anzahl derselben keine wesentlichen Zusatzmassen während der Verseilung der Verseilelemente zu bewegen sind. Sie haben insgesamt ein geringes Rotationsträgheitsmoment, so daß die Umkehrzeiten bei der Verseilung sehr klein gehalten werden können. Bei ausreichend hoher Anzahl von Halteelementen sind die Verseilelemente während der Verseilung einwandfrei geführt. Ein Verheddern derselben ist ausgeschlossen.This device is very simple. It consists of the guide disc and the stranding disc and a number of holding elements, which is determined by the length of the distance between the guide and stranding disc. When setting up the device, the stranding elements only need to be pulled through the through holes of all axially relatively short holding elements. The holding elements can be made of a material with a low coefficient of friction, so that the stranding elements are exposed to a relatively low friction during manufacture. The holding elements are low in mass, so that even with a larger number of them no significant additional masses are to be moved during the stranding of the stranding elements. Overall, they have a low rotational moment of inertia, so that the reversal times during stranding can be kept very short. With a sufficiently high number of holding elements, the stranding elements are guided properly during the stranding. Tangling is impossible.

Gemäß einem weiteren Gedanken der Erfindung ist das Tragelement als entlang einer gemeinsamen Achse von Führungsscheibe und Verseilscheibe verlaufendes, unter Zugspannung stehendes Torsionselement ausgebildet, das verdrehsicher an der Verseilscheibe angebracht ist und an dem mit Abstand zur Führungsscheibe einerseits und zur Verseilscheibe andererseits mindestens ein Halteelement verdrehsicher befestigt ist. Das Torsionselement besteht aus mindestens zwei möglichst eng benachbarten, fadenförmigen Strängen und zwischen je zwei Halteelementen sowie zwischen Führungsscheibe bzw. Verseilscheibe und dem nächstliegenden Halteelement ist jeweils eine das Torsionselement lose umgebende Abdeckung um dasselbe herumgelegt.According to a further idea of the invention, the support element is designed as a torsion element which runs along a common axis of the guide disk and the stranding disk and is under tensile stress, which is attached to the stranding disk in a manner preventing rotation and to which at least one holding element is secured against rotation on the one hand at a distance from the guide disk and on the other hand to the stranding disk is. The torsion element consists of at least two thread-like strands that are as closely adjacent as possible and a cover loosely surrounding the torsion element is placed around the same between two holding elements and between the guide disk or stranding disk and the closest holding element.

Die Führung der Verseilelemente wird dadurch verbessert, daß die Halteelemente verdrehsicher am Torsionselement angebracht sind. Sie machen dadurch die von der Verseilscheibe bewirkte Drehung des Torsionselements mit. Das ist insbesondere durch die Aufteilung des Torsionselements in mindestens zwei Stränge sichergestellt, die unter Berücksichtigung des Aufbaus eines herzustellenden Verseilverbundes möglichst eng benachbart sind. Die zwischen den einzelnen Halteelementen sowie je einem Halteelement und Führungs- bzw. Verseilscheibe angebrachten Abdeckungen schützen die Verseilelemente während des Verseilvorgangs gegen Beschädigungen, die sonst durch das Torsionselement hervorgerufen werden könnten, ohne die Bewegung der einzelnen Stränge des Torsionselements zu behindern.The guidance of the stranding elements is improved in that the holding elements are attached to the torsion element so that they cannot rotate. As a result, they participate in the rotation of the torsion element caused by the stranding disk. This is ensured in particular by dividing the torsion element into at least two strands which are as closely adjacent as possible, taking into account the structure of a stranded composite to be produced. The between the individual holding elements and one each Covers attached to the retaining element and the guide or stranding disk protect the stranding elements during the stranding process against damage which could otherwise be caused by the torsion element without impeding the movement of the individual strands of the torsion element.

Die Erfindung wird im folgenden für eine Vorrichtung erläutert, mit der drei Verseilelemente verseilt werden können. Bei entsprechender Gestaltung von Führungs- und Verseilscheibe sowie Halteelementen können auch zwei oder mehr als drei Verseilelemente verarbeitet werden. Fig. 1 gibt dabei nur eine Prinzipdarstellung wieder, in der die eigentliche Verseilstrecke bzw. der Verseilspeicher nur angedeutet ist.The invention is explained below for a device with which three stranding elements can be stranded. With a corresponding design of the guide and stranding disk as well as holding elements, two or more than three stranding elements can also be processed. Fig. 1 gives only a schematic diagram again, in which the actual stranding path or the stranding memory is only indicated.

Gemäß Fig. 1 werden drei Verseilelemente 1 - im folgenden stellvertretend für alle anderen Möglichkeiten als "Adern 1" bezeichnet - von Spulen 2 abgezogen und einer Führungsscheibe 3 zugeführt. Nach Durchlaufen einer Verseilstrecke 4, deren genauerer Aufbau aus den Fig. 2, 7 und 8 hervorgeht, gelangen die Adern 1 zu einer Verseilscheibe 5. Sie werden in einem Verseilpunkt 6 reversierend zu einer Seele 7 miteinander verseilt, die in Richtung des Pfeiles 8 abgezogen wird.1, three stranding elements 1 - hereinafter referred to as "cores 1" as representative of all other possibilities - are drawn off from coils 2 and fed to a guide disk 3. After passing through a stranding section 4, the more precise structure of which is shown in FIGS. 2, 7 and 8, the cores 1 reach a stranding disk 5. They are reversed stranded together in a stranding point 6 to form a core 7, which is drawn off in the direction of arrow 8 becomes.

Die Verseilscheibe 5 ist drehbar gelagert, was durch eine Lagerstelle 9 angedeutet ist. Sie kann reversierend um ihre Achse gedreht werden. Dazu wird in bekannter Technik ein Elektromotor 10 verwendet. Im Betrieb der Vorrichtung führt die Verseilscheibe 5 beispielsweise jeweils acht Umdrehungen in beiden Drehrichtungen aus. Von der Nullage ausgesehen, sind das in jeder Drehrichtung vier Umdrehungen.The stranding disk 5 is rotatably supported, which is indicated by a bearing 9. It can be rotated around its axis in a reversing manner. For this purpose, an electric motor 10 is used in known technology. During operation of the device, the stranding disk 5, for example, makes eight revolutions in both directions of rotation. From the zero position, this is four revolutions in each direction of rotation.

Der Verseilpunkt 6 ist ein Fixpunkt, in dem die Adern 1 so fest gehalten werden, daß ihr wegen der reversierenden Verseilung an sich lockerer Verbund nicht wieder aufgehen kann. Hier können beispielsweise ein Rollenpaar, eine Öse oder ein Nippel eingesetzt werden. Hinter dem Verseilpunkt 6 wird eine Halterung auf die Seele 7 aufgebracht. Dazu können ein Band aufgewickelt oder ein Mantel aufgespritzt werden. Die Seele 7 kann auf eine Spule aufgewickelt oder weiteren Bearbeitungsstationen zugeführt werden.The stranding point 6 is a fixed point in which the cores 1 are held so firmly that, due to the reversing stranding, the loosely bonded connection cannot open again. For example, a pair of rollers, an eyelet or a nipple can be used here. After the stranding point 6, a holder is applied to the core 7. This can be done by winding a tape or spraying on a coat. The core 7 can be wound onto a spool or fed to further processing stations.

In der Verseilstrecke 4 sind gemäß Fig. 2 zwei als Scheiben dargestellte Halteelemente 11 angebracht, und zwar mit Abstand zueinander sowie zu der Führungsscheibe 3 und der Verseilscheibe 5. Die Halteelemente 11 sind an einem fadenförmigen, zugfesten Tragelement 12 befestigt, das zwischen Führungsscheibe 3 und Verseilscheibe 5 entlang deren gemeinsamer Achse angeordnet ist.According to FIG. 2, two holding elements 11, shown as disks, are attached in the stranding section 4, at a distance from one another and to the guide disk 3 and the stranding disk 5. The retaining elements 11 are fastened to a thread-like, tensile support element 12, which is located between the guide disk 3 and Stranding disc 5 is arranged along the common axis.

Führungsscheibe 3, Verseilscheibe 5 und Halteelemente 11 haben im dargestellten Ausführungsbeispiel jeweils drei in axialer Richtung verlaufende Durchgangslöcher 13, durch welche die Adern 1 hindurchgezogen werden. Das Tragelement 12 kann aus Stahl oder Kunststoff bestehen, beispielsweise aus Aramid. Es ist fest in Führungsscheibe 3 und Verseilscheibe 5 angebracht, kann sich aber in einer Ausführungsform der Vorrichtung in beiden Scheiben frei drehen. Das kann auch für die Halteelemente 11 gelten. Das Tragelement 12 ist in bevorzugter Ausführungsform zwischen Führungsscheibe 3 und Verseilscheibe 5 gespannt. Dazu kann ein Spannelement eingesetzt werden, das auf der Seite der Führungsscheibe 3 oder der Verseilscheibe 5 angebracht wird. Als Spannelement können beispielsweise eine Feder, ein Gewicht oder ein Pneumatikzylinder eingesetzt werden.Guide disk 3, stranding disk 5 and holding elements 11 each have three through holes 13 running in the axial direction, through which the wires 1 are pulled. The support element 12 can consist of steel or plastic, for example of aramid. It is firmly attached in the guide disc 3 and stranding disc 5, but can rotate freely in both discs in one embodiment of the device. This can also apply to the holding elements 11. In a preferred embodiment, the support element 12 is stretched between the guide disk 3 and the stranding disk 5. For this purpose, a tensioning element can be used, which is attached to the side of the guide disk 3 or the stranding disk 5. For example, a spring, a weight or a pneumatic cylinder can be used as the clamping element.

Während die Führungsscheibe 3 und die Verseilscheibe 5 vorzugsweise aus Metall bestehen, wird für die Halteelemente 11 leichteres Material, insbesondere Kunststoff, bevorzugt. Sie bestehen beispielsweise aus Polyamid oder Polytetrafluorethylen. Diese Materialien haben besonders gute Gleiteigenschaften. Die Durchgangslöcher 13 der Haltescheiben 11 können zum leichteren Durchziehen der Adern 1 entgegen der Abzugsrichtung (Pfeil 8) vorzugsweise konisch aufgeweitet sein, so wie es in Fig. 5 dargestellt ist.While the guide disk 3 and the stranding disk 5 preferably consist of metal, lighter material, in particular plastic, is preferred for the holding elements 11. They consist for example of polyamide or polytetrafluoroethylene. These materials have particularly good sliding properties. The through holes 13 of the holding disks 11 can preferably be flared in order to make it easier to pull the wires 1 against the pull-off direction (arrow 8), as shown in FIG. 5.

Führungsscheibe 3, Verseilscheibe 5 und Halteelemte 11 können gemäß Fig. 4 jeweils auch ein zentrales Durchgangsloch 14 haben. Durch die zentralen Durchgangslöcher 14 kann ein Kern oder Grundelement beliebigen Aufbaus gezogen werden, um den bzw. das die Adern 1 reversierend herumverseilt werden. Es ist auch möglich, in den zentralen Durchgangslöchern 14 ein Rohr anzuordnen, durch das Kern oder Grundelement hindurchgezogen werden. Das zentrale Tragelement 12 wird bei dieser Ausführungsform der Scheiben 3 und 5 und der Halteelemente 11 durch mindestens zwei Tragelemente 15 ersetzt, so wie es aus den Fig. 4 und 8 hervorgeht. Die Tragelemente 15 sind in bevorzugter Ausführungsform symmetrisch in Umfangsrichtung aller Scheiben und Halteelemente 11 verteilt. Auch auf den Tragelementen 15 können die Halteelemente 11 lose und an sich axial beweglich angebracht sein. Die axiale Position der Halteelemente 11 auf den Tragelementen 12 bzw. 15 wird dann entsprechend Fig. 6 durch Klemmen 16 fixiert, die auf beiden Seiten der Halteelemente 11 fest auf dem jeweiligen Tragelement 12 bzw. 15 angebracht sind. Wenn zwei oder mehr Tragelemente 15 vorhanden sind, reicht es aus, wenn die Klemmen 16 nur auf einem dieser Tragelemente angebracht werden.Guide disk 3, stranding disk 5 and holding elements 11 can each also have a central through hole 14 according to FIG. 4. A core or basic element of any structure can be drawn through the central through holes 14, around which the wires 1 are reversibly stranded. It is also possible to arrange a tube in the central through holes 14 through which the core or base element is drawn. In this embodiment of the disks 3 and 5 and the holding elements 11, the central support element 12 is replaced by at least two support elements 15, as can be seen from FIGS. 4 and 8. The In a preferred embodiment, support elements 15 are distributed symmetrically in the circumferential direction of all disks and holding elements 11. The holding elements 11 can also be attached to the support elements 15 in a loose and axially movable manner. The axial position of the holding elements 11 on the supporting elements 12 or 15 is then fixed according to FIG. 6 by clamps 16 which are fixedly attached to the respective supporting element 12 or 15 on both sides of the holding elements 11. If two or more support elements 15 are present, it is sufficient if the clamps 16 are only attached to one of these support elements.

Zwischen Führungsscheibe 3 und Verseilscheibe 5 ist mindestens ein Halteelement 11 angeordnet. Die Anzahl der Halteelemente 11 richtet sich nach den Eigenschaften der zu verarbeitenden Adern 1 und nach der Entfernung zwischen Führungsscheibe 3 und Verseilscheibe 5. Je größer diese Entfernung ist, desto mehr Haltescheiben 11 werden eingesetzt. Ihr jeweiliger Abstand voneinander kann gleichbleibend aber auch beliebig sein. In bevorzugter Ausführungsform wird der Abstand der Halteelemente 11 voneinander mit zunehmender Entfernung von der Führungsscheibe 3 kleiner, so wie es aus den Fig. 7 und 8 hervorgeht. Im Bereich der Verseilscheibe 5 sind also zur Führung der Adern 1 mehr Halteelemente 11 vorhanden als im Bereich der Führungsscheibe 3. Die Adern 1 sind dadurch in dem Bereich mit den größeren Drehwinkeln enger geführt.At least one holding element 11 is arranged between the guide disk 3 and the stranding disk 5. The number of holding elements 11 depends on the properties of the wires 1 to be processed and on the distance between the guide disk 3 and the stranding disk 5. The greater this distance, the more retaining disks 11 are used. Their respective distance from one another can be constant but also arbitrary. In a preferred embodiment, the distance of the holding elements 11 from one another becomes smaller with increasing distance from the guide disk 3, as can be seen from FIGS. 7 and 8. In the area of the stranding disk 5 there are therefore more holding elements 11 for guiding the wires 1 than in the area of the guide disk 3. The wires 1 are thus guided more closely in the area with the larger angles of rotation.

In einer weiteren Ausführungsform der Vorrichtung ist das Tragelement 12 als Torsionselement ausgeführt. Es wird daher im folgenden als "Torsionselement 12" bezeichnet. Führungsscheibe 3, Verseilscheibe 5 und Halteelemente 11 sind verdrehsicher am Torsionselement 12 befestigt. Während des Verseilvorgangs wird die Verseilscheibe 5 durch den Motor 10 mit wechselnder Drehrichtung angetrieben. Das ist in Fig. 2 durch den Pfeil 17 angedeutet. Da die Verseilscheibe 5 verdrehsicher mit dem Torsionselement 12 verbunden ist, wird dasselbe bei der Drehung der Verseilscheibe 5 tordiert. Es nimmt dadurch die ebenfalls verdrehsicher mit demselben verbundenen Halteelemente 11 mit, die dementsprechend ebenfalls mit wechselnder Drehrichtung gedreht werden. Das ist in Fig. 2 durch die Pfeile 18 und 19 angedeutet.In a further embodiment of the device, the support element 12 is designed as a torsion element. It is therefore referred to below as "torsion element 12". Guide disc 3, stranding disc 5 and holding elements 11 are secured against rotation on the torsion element 12. During the stranding process, the stranding disk 5 is driven by the motor 10 with an alternating direction of rotation. This is indicated in Fig. 2 by the arrow 17. Since the stranding disk 5 is connected to the torsion element 12 so that it cannot rotate, the same is twisted when the stranding disk 5 rotates. It thereby takes the holding elements 11, which are likewise connected to the same in a rotationally secure manner, and which accordingly are also rotated with an alternating direction of rotation. This is indicated in Fig. 2 by the arrows 18 and 19.

Das Torsionselement 12 besteht gemäß Fig. 9 aus drei möglichst eng benachbarten fadenförmigen Strängen 20. Die Stränge 20 liegen in bevorzugter Ausführungsform so dicht zusammen, daß sich ein zentrales Torsionselement 12 mit möglichst geringen radialen Abmessungen ergibt. Es sollen mindestens zwei Stränge 20 eingesetzt werden. Es können aber auch mehr als drei Stränge 20 sein. Ihre Anzahl kann sich nach der Anzahl der zu verarbeitenden Adern 1 richten. Durch die Aufteilung des Torsionselements 12 in mindestens zwei Stränge 20 ist ein stabiles Torsionselement gegeben, an dem die Halteelemente 11 auf einfache Weise verdrehsicher angebracht werden können.According to FIG. 9, the torsion element 12 consists of three thread-like strands 20 which are as closely adjacent as possible. In a preferred embodiment, the strands 20 lie so close together that a central torsion element 12 results with the smallest possible radial dimensions. At least two strands 20 are to be used. However, there can also be more than three strands 20. Their number can depend on the number of wires 1 to be processed. By dividing the torsion element 12 into at least two strands 20, a stable torsion element is provided, on which the holding elements 11 can be attached in a simple manner to prevent rotation.

Die Adern 1 legen sich während der Verseilung an das Torsionselement 12 an. Um eine Beschädigung derselben durch das Torsionselement 12 zu vermeiden, ist um dasselbe eine schützende Abdeckung lose herumgelegt. Diese Abdeckung besteht in bevorzugter Ausführungsform aus Schläuchen 21 aus Kunststoff, die lose über dem Torsionselement 12 bzw. über den Strängen 20 liegen. Die Schläuche 21 reichen jeweils von einem Halteelement 11 bis zum nächsten. Sie liegen auch zwischen Führungsscheibe 3 bzw. Verseilscheibe 5 und dem jeweils nächsten Halteelement 11. Die Verdrehung der Stränge 20 des Torsionselements 12 wird durch die Schläuche 21 nicht behindert. Die Schläuche 21 bestehen vorzugsweise aus einem möglichst glatten Material mit guten Gleiteigenschaften, wie beispielsweise Polytetrafluorethylen oder Polyamid.The wires 1 lay against the torsion element 12 during the stranding. In order to avoid damage to the torsion element 12, a protective cover is loosely wrapped around it. In a preferred embodiment, this cover consists of hoses 21 made of plastic, which lie loosely over the torsion element 12 or over the strands 20. The tubes 21 each extend from one holding element 11 to the next. They are also between the guide disk 3 or stranding disk 5 and the next holding element 11 in each case. The hoses 21 do not obstruct the rotation of the strands 20 of the torsion element 12. The tubes 21 are preferably made of the smoothest possible material with good sliding properties, such as polytetrafluoroethylene or polyamide.

Die Halteelemente 11 sind in Fig. 2 als Scheiben dargestellt. In bevorzugter Ausführungsform bestehen sie gemäß Fig. 10 aus Ringen 22, die durch die Stränge 20 zu einem Halteelement 11 zusammengefaßt sind. Jedem Ring 22 ist dabei ein Strang 20 zugeordnet, so daß die Ringe 22 durch die Stränge 20 gegeneinander gedrückt werden. Die axiale Position eines solchen Halteelements 11 ist durch die beiden angrenzenden Schläuche 21 fixiert. Diese Ausführungsform ist besonders massearm. Die Ringe 22 und damit die Adern 1 werden bei einer Verdrehung der Stränge 20 von diesen mitgenommen und dadurch in Umfangsrichtung gedreht. Das gilt auch für die Ausführungsform der Halteelemente 11 nach Fig. 11, bei welcher statt der Ringe 22 Scheiben 23 eingesetzt sind, in denen die Durchgangslöcher 13 angebracht sind. Auch hier ist jeder Scheibe 23 ein Strang 20 des Torsionselements 12 zugeordnet.The holding elements 11 are shown in FIG. 2 as disks. In a preferred embodiment, they consist of rings 22 according to FIG. 10, which are combined by the strands 20 to form a holding element 11. Each ring 22 is assigned a strand 20 so that the rings 22 through the strands 20th pressed against each other. The axial position of such a holding element 11 is fixed by the two adjacent hoses 21. This embodiment is particularly low in mass. When the strands 20 are twisted, the rings 22 and thus the wires 1 are carried along by them and thereby rotated in the circumferential direction. This also applies to the embodiment of the holding elements 11 according to FIG. 11, in which 22 disks 23 are used instead of the rings, in which the through holes 13 are made. Here, too, a strand 20 of the torsion element 12 is assigned to each disk 23.

Ein Torsionselement 12 aus möglichst eng benachbarten Strängen 20 kann auch dann eingesetzt werden, wenn eine Seele 7 mit einem zentral durchgeführten Kern 24 hergestellt werden soll. Ein dafür verwendbares Halteelement 11 geht aus Fig. 12 hervor. Der Kern 24 wird in der Vorrichtung nicht mit verseilt. Er dient nur als Unterlage für die reversierend verseilten Adern 1. Als Kern 24 kann beispielsweise ein vorgefertigtes Bündel aus Adern verwendet werden. Der Kern 24 wird durch ein Rohr 25 hindurchgeführt, um das die Stränge 20 des Torsionselements 12 herum angeordnet sind. Sie liegen damit wieder so eng wie möglich zusammen. Auch hier sind über den Strängen 20 die Schläuche 21 angeordnet. In Fig. 12 sind sechs Stränge 20 dargestellt, die sechs Ringe 22 zu einem Halteelement 11 verbinden. Ein ähnlicher Aufbau ergibt sich, wenn statt der Ringe 22 wieder Scheiben 23 verwendet werden. Auch hier ist die Anzahl der Ringe 22 bzw. Scheiben 23 und damit die Anzahl der Stränge 20 wieder beliebig. Es müssen nur jeweils mindestens zwei sein.A torsion element 12 consisting of strands 20 which are as closely adjacent as possible can also be used if a core 7 is to be produced with a core 24 which is carried out centrally. A holding element 11 that can be used for this purpose is shown in FIG. 12. The core 24 is not stranded in the device. It only serves as a base for the reversely stranded cores 1. For example, a prefabricated bundle of cores can be used as the core 24. The core 24 is passed through a tube 25 around which the strands 20 of the torsion element 12 are arranged. They are as close together as possible. Here, too, the hoses 21 are arranged above the strands 20. FIG. 12 shows six strands 20 which connect six rings 22 to form a holding element 11. A similar structure results if disks 23 are used again instead of the rings 22. Here, too, the number of rings 22 or disks 23 and thus the number of strands 20 is again arbitrary. It only has to be at least two at a time.
