Description

Die Erfindung betrifft eine Vorrichtung zum Speichern von von einer Vorratsspule abziehbarem fadenförmigem Material, z. B. Schussgarn, Draht, Band usw., insbesondere an einer Webmaschine, mit einem Wickelkörper, der einen um eine Drehachse angeordneten Tragteil und eine auf diesem angebrachte, eine zentrale Achse aufweisende, im wesentlichen zylinderförmige Wickeltrommel sowie eine Anzahl zur Wickeltrommel radial einstellbare Umfangselemente zur Führung des auf dem Umfang des Wickelkörpers in einer einlagigen Wicklung speicherbaren und vom Wickelkörper in axialer Richtung über Kopf abziehbaren fadenförmigen Materials enthält.The invention relates to a device for storing removable from a supply spool thread-like material, for. B. weft, wire, ribbon, etc., in particular on a weaving machine, with a winding body, which has a support part arranged around an axis of rotation and an attached to it, having a central axis, substantially cylindrical winding drum and a number of radially adjustable circumferential elements to the winding drum Contains the thread-like material that can be stored in a single-layer winding on the circumference of the winding body and can be pulled off the winding body in the axial direction.

Bei einer durch die FR-A-2 428 603 bekannten Vorrichtung der genannten Art ist die Wickeltrommel bezüglich der Drehachse exzentrisch im Randbereich einer gegen Drehung gesicherten Tragscheibe feststehend angebracht. Entsprechend der jeweiligen Radialposition der Umfangselemente, welche mit einer Umfangspartie der Wickeltrommel jeweils eine vieleckige bis annähernd kreisförmige Führungsbahn für das zu speichernde fadenförmigen Materialbestimmen, können unterschiedliche Wickeldurchmesser eingestellt werden. Dabei verläuft lediglich die dem grössten Wickeldurchmesser entsprechende Führungsbahn im wesentlichen konzentrisch zur Drehachse, während die den kleineren Wickeldurchmessern entsprechenden Führungsbahnen je zur Drehachse exzentrisch verlaufen. Die dem abnehmenden Wickeldurchmesser entsprechend zunehmende Exzentrizität der Fadenwicklung kann insbesondere bei den kleinen Wickeldurchmessern zu diskontinuierlichen Beanspruchungen und damit zu Spannungsschwankungen in dem von der Vorratsspule zum Wickelkörper verlaufenden Abschnitt des fadenförmigen Materials führen.In a device of the type mentioned which is known from FR-A-2 428 603, the winding drum is fixedly mounted eccentrically with respect to the axis of rotation in the edge region of a carrier disk secured against rotation. Different winding diameters can be set in accordance with the respective radial position of the peripheral elements, which each determine a polygonal to approximately circular guideway for the thread-like material to be stored with a peripheral portion of the winding drum. In this case, only the guideway corresponding to the largest winding diameter runs essentially concentrically to the axis of rotation, while the guideways corresponding to the smaller winding diameters each run eccentrically to the axis of rotation. The increasing eccentricity of the thread winding in accordance with the decreasing winding diameter can lead to discontinuous stresses, particularly in the case of the small winding diameters, and thus to voltage fluctuations in the section of the thread-like material running from the supply reel to the winding body.

Der Erfindung liegt die Aufgabe zugrunde, eine in dieser Hinsicht verbesserte, weiterentwickelte Vorrichtung der eingangs genannten Art zu schaffen, die einen kontinuierlichen, schonenden Abzug des fadenförmigen Materials von der Vorratsspule gestattet.The invention has for its object to provide an improved in this respect, further developed device of the type mentioned, which allows a continuous, gentle removal of the thread-like material from the supply spool.

Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass die Wickeltrommel am Tragteil quer zur Drehachse verstellbar befestigt ist.This object is achieved according to the invention in that the winding drum is fastened to the support part so as to be adjustable transversely to the axis of rotation.

Bei der erfindungsgemäss ausgebildeten Speichervorrichtung sind in jeder bezüglich der Drehachse exzentrischen Stellung der Wickeltrommel die Umfangselemente je in eine Radialstellung zur Wickeltrommel einstellbar, in der ihre bezüglich der zentralen Achse der Wickeltrommel peripheren Partien, welche in einer zur zentralen Achse senkrecht verlaufenden Ebene liegen, und die in der gleichen Ebene liegende, von der Drehachse am weitesten entfernte Umfangspartie der Wickeltrommel einen zur Drehachse konzentrischen umschriebenen Kreis bestimmen, dessen Durchmesser zwischen den durch die entsprechenden Abmessungen des Tragteils und der Wickeltrommel gegebenen Grenzen frei einstellbar ist. Diese Anordnung gewährleistet bei allen Wickeldurchmessern eine im wesentlichen konstante, besonders geringe Beanspruchung des Fadenmaterials und ist damit insbesondere für die Verarbeitung von empfindlichem Fadenmaterial geeignet.In the storage device designed according to the invention, in each position of the winding drum that is eccentric with respect to the axis of rotation, the peripheral elements can each be set in a radial position to the winding drum in which their peripheral parts with respect to the central axis of the winding drum, which lie in a plane perpendicular to the central axis, and the In the same plane, the most distant circumferential part of the winding drum from the axis of rotation, determine a circumscribed circle concentric to the axis of rotation, the diameter of which can be freely adjusted between the limits given by the corresponding dimensions of the supporting part and the winding drum. This arrangement ensures an essentially constant, particularly low stress on the thread material for all winding diameters and is therefore particularly suitable for processing sensitive thread material.

Nach einer Ausführungsform der Erfindung, welche auf besonders einfache und betriebssichere Weise, unter Beibehaltung einer genau definierten Verbindungsstelle zwischen den relativ zueinander verstellbaren Teilen, eine genaue Einstellung des jeweils gewünschten Wickeldurchmessers gestattet, kann die Wickeltrommel am Tragteil um eine gegenüber der Drehachse und gegenüber der zentralen Achse der Wickeltrommel versetzt angeordnete Schwenkachse verschwenkbar angelenkt und um diese Schwenkachse verstellbar befestigbar sein.According to one embodiment of the invention, which allows a precise setting of the desired winding diameter in a particularly simple and reliable manner, while maintaining a precisely defined connection point between the parts that can be adjusted relative to one another, the winding drum on the support part can be turned relative to the axis of rotation and the central one The axis of the winding drum is pivotally articulated and can be pivotally articulated and can be fastened adjustably about this pivot axis.

Dabei ist es besonders zweckmässig, wenn die Schwenkachse der Wickeltrommel gegenüber deren zentraler Achse und gegenüber der Drehachse je um den gleichen Betrag versetzt ist. Entsprechend kann auch die Wickeltrommel allein - ohne Verwendung von Umfangselementen - konzentrisch zur Drehachse des Wickelkörpers eingestellt werden, so dass auch bei dem durch den Durchmesser der Wickeltrommel gegebenen kleinsten Wickeldurchmesser des Wickelkörpers das Aufwickeln des zu speichernden fadenförmigen Materials mit im wesentlichen konstanter Spannung gewährleistet wird.It is particularly expedient if the pivot axis of the winding drum is offset by the same amount with respect to its central axis and with respect to the axis of rotation. Correspondingly, the winding drum alone can also be adjusted concentrically to the axis of rotation of the winding body without using circumferential elements, so that even with the smallest winding diameter of the winding body given by the diameter of the winding drum, the winding of the filamentary material to be stored is ensured with essentially constant tension.

Eine Vorrichtung in einer besonders kompakten, betriebssicheren Bauweise kann in weiterer Ausgestaltung der Erfindung dadurch erzielt werden, dass mindestens zwei an der Stirnseite der Wickeltrommel um deren zentrale Achse gegeneinander versetzt angreifende, gegen den Tragteil verspannbare Halteteile vorgesehen sind.A device in a particularly compact, reliable construction can be achieved in a further embodiment of the invention by providing at least two holding parts which are offset against one another on the end face of the winding drum and act against one another around the central axis thereof and can be braced against the supporting part.

Nach einer Ausführungsform der Erfindung kann auf besonders einfache Weise eine präzise und zudem über den ganzen Verstellbereich stufenlose Einstellung der Wickeldurchmesser des Wickelkkörpers dadurch erzielt werden, dass der Tragteil mindestens zwei an seiner der Wickeltrommel zugekehrten Stirnseite ausgebildete Führungsschlitze zum Führen je eines der Halteteile enthält.According to one embodiment of the invention, the winding diameter of the winding body can be adjusted in a particularly simple manner and also continuously over the entire adjustment range in that the support part contains at least two guide slots formed on its end face facing the winding drum for guiding each of the holding parts.

Im Zusammenhang mit einer an den Tragteil angelenkten Wickeltrommel kann die Einstellung des Wickeldurchmessers dadurch erleichtert werden, dass die Führungsschlitze kreisbogenförmig ausgebildet und konzentrisch zur Schwenkachse der Wickeltrommel angeordnet sind.In connection with a winding drum hinged to the supporting part, the setting of the winding diameter can be facilitated by the fact that the guide slots are formed in a circular arc and are arranged concentrically to the pivot axis of the winding drum.

An einer Vorrichtung mit in der Wickeltrommel angeordneten Führungselementen, die je durch eine am Umfang der Wickeltrommel vorgesehenen Öffnung von innen her zwischen zwei Windungen des fadenförmigen Materials und zurück führbar sind, können in weiterer Ausgestaltung der Erfindung die Führungselemente über eine in der Wickeltrommel gelagerte, gegenüber der Drehachse des Wickelkörpers versetzte Welle antreibbar sein, welche mit einer die Drehachse des Wickelkorpers bestimmenden Antriebswelle relativ zu dieser verstellbar getrieblich verbunden ist. Durch diese Anordnung kann in jeder Stellung der Wickeltrommel der vom Maschinenantrieb abgeleitete Antrieb der Führungselemente gewährleistet werden, welche jeweils ein auf dem Wickelkörper gespeichertes, für einen folgenden Schusseintrag bereitgestelltes Wicklungspaket von dem für einen weiteren Schusseintrag zu bildenden Wicklungspaket trennen.On a device with guide elements arranged in the winding drum, each between the inside through an opening provided on the circumference of the winding drum two turns of the thread-like material and can be guided back, in a further embodiment of the invention the guide elements can be driven via a shaft which is mounted in the winding drum and is offset relative to the axis of rotation of the winding body and which is connected to a drive shaft which determines the axis of rotation of the winding body in an adjustable manner relative to the latter is. With this arrangement, in each position of the winding drum, the drive of the guide elements derived from the machine drive can be ensured, each of which separates a winding package stored on the winding body and made available for a subsequent weft insertion from the winding package to be formed for a further weft insertion.

Bei einer Vorrichtung mit Führungselementen, welche an einem Drehkörper ausgebildet sind, der um eine bezüglich der Drehachse des Wickelkörpers quer gestellte Achse drehbar angeordnet ist, kann nach einer Ausführungsform der Erfindung eine besonders kompakte Bauweise mit einer relativ geringen Abmessung der Vorrichtung in axialer Richtung dadurch erzielt werden, dass der Tragteil an seiner der Wickeltrommel zugekehrten Stirnseite eine dem Bewegungsbereich des jeweils mit der Wickeltrommel verstellbaren Drehkörpers entsprechende Ausnehmung enthält, welche zur Aufnahme eines in den Bereich des Tragteils einfübaren Abschnitts der Umfangspartie des Drehkörpers geeignet ist.In a device with guide elements which are formed on a rotating body which is arranged rotatably about an axis which is transverse to the axis of rotation of the winding body, a particularly compact design with a relatively small dimension of the device in the axial direction can thereby be achieved according to one embodiment of the invention be that the support part on its end facing the winding drum contains a recess corresponding to the range of motion of the rotating body adjustable with the winding drum, which is suitable for receiving a portion of the peripheral part of the rotating body that can be inserted into the area of the supporting part.

Corresponding peripheral elements, the design and attachment thereof to the winding drum 15 and to the base plate 14 are not the subject of the present invention, for. B. from FR-A-2 428 603 known. In the operating position of the winding drum 15, which is shown in FIGS. 1 and 2 and is coaxial with the axis of rotation 8, the peripheral elements 18 are omitted, one of which is indicated by dash-dotted lines in FIG. 1. The base plate 14 is supported by ball bearings 21, of which only one is shown in FIG. 1, on a drive shaft 22 which is fixedly connected to the drive body 6 and on which a gearwheel 23 is wedged. The base plate 14 and the winding drum 15 connected to it are secured against rotation in a manner to be described by a fork-shaped guide bracket 20 adjustably fastened to the housing 2.

Die Wickeltrommel 15 ist an der Grundscheibe 14 um eine zur Drehachse 8 und zur zentralen Achse 16 parallele, gegenüber diesen Achsen je um einen gleichen Betrag exzentrisch versetzte Achse 24 einer Welle 25 verschwenkbar angelenkt und durch Schrauben 26 um diese Achse 24 verstellbar befestigt. Die Welle 25 ist mit einer Antriebsschnecke 25a versehen und über Kugellager 27 und 28 in der Grundscheibe 14 sowie in einem in der Wickeltrommel 15 angeordneten Getriebegehäuse 30 gelagert. An dem der Grundscheibe 14 zugekehrten Ende der Welle 25 ist ein Zahnrad 31 befestigt, welches mit dem Zahnrad 23 der Antriebswelle 22 kämmt. Die Antriebsschnecke 25a ist mit einem Schneckenrad 32 in Eingriff, welches mit einem Sternrad 33 auf einer quer zur axialen Erstreckung der Wickeltrommel 15 angeordneten Welle 34 befestigt ist. Die Welle 34 ist über Kugellager 35 im Getriebegehäuse 30 gelagert.The winding drum 15 is pivotally articulated on the base plate 14 about an axis 24 of a shaft 25 which is parallel to the axis of rotation 8 and the central axis 16 and is eccentrically offset by an equal amount relative to these axes and is adjustably fastened by screws 26 about this axis 24. The shaft 25 is provided with a drive worm 25a and is supported by ball bearings 27 and 28 in the base plate 14 and in a gear housing 30 arranged in the winding drum 15. A gear 31 is attached to the end of the shaft 25 facing the base plate 14, which meshes with the gear 23 of the drive shaft 22. The drive worm 25a is in engagement with a worm wheel 32, which is fastened with a star wheel 33 on a shaft 34 arranged transversely to the axial extension of the winding drum 15. The shaft 34 is supported in the gear housing 30 via ball bearings 35.

Am Sternrad 33 sind Zähne 36 ausgebildet, welche durch einen am Umfang der Wickeltrommel 15 ausgebildeten, im wesentlichen parallel zur Achse 16 verlaufenden Schlitz 37 zwischen zwei Arme 20a 20b des Führungsbügels 20 einführbar sind.On the star wheel 33 teeth 36 are formed, which by a on the circumference of the Winding drum 15 formed slot 37 extending substantially parallel to the axis 16 between two arms 20a 20b of the guide bracket 20 can be inserted.

Während des Betriebs rotiert der Antriebskörper 6 mit dem Zahnrad 23 und dem Führungsrohr 9 gemäss Pfeil 38 um die Drehachse 8, wobei das Eintrittsende des Führungsrohrs 9 immer im Bereich der Drehachse 8 verbleibt. Der vom Austrittsende des Führungsrohrs 9 ablaufende Schussfaden 12 wird auf eine relativ stark konische Umfangspartie 15b der Wickeltrommel 15 in Fadenwindungen aufgelegt. Diese werden anschliessend durch die Zähne 36 des über die Welle 25 angetriebenen Sternrades 33 über die im wesentlichen zylindrische oder, wie dargestellt, schwach konische Umfangspartie 15c der Wickeltrommel 15 in Fig. 1 nach rechts geschoben und während des Schusseintrags jeweils absatzweise über das Kopfende 15a der Wickeltrommel 15 abgezogen.During operation, the drive body 6 rotates with the gear 23 and the guide tube 9 according to arrow 38 about the axis of rotation 8, the entry end of the guide tube 9 always remaining in the region of the axis of rotation 8. The weft thread 12 running from the outlet end of the guide tube 9 is placed on a relatively strongly conical peripheral portion 15b of the winding drum 15 in thread turns. These are then pushed through the teeth 36 of the star wheel 33 driven by the shaft 25 over the substantially cylindrical or, as shown, weakly conical peripheral portion 15c of the winding drum 15 in FIG Pulled winding drum 15.

Wie insbesondere aus der Fig. 3 hervorgeht, können in der Grundscheibe 14 drei kreisbogenförmige Schlitze 41, 42 und 43 ausgebildet sein, die zur Achse 24 konzentrisch gegeneinander in Umfangsrichtung versetzt angeordnet sind. In den Schlitzen 41, 42 und 43 sind die an der Wickeltrommel 15 angreifenden, je in einer Führungshülse 44 angeordneten Schrauben 26 geführt, welche entsprechende Verschwenkungen derWickeitromme) 15 um die Achse 24 und damit unterschiedliche Einstellungen der Wickeltrommel 15 quer zur Drehachse 8 auf der Grundscheibe 14 zulassen. Die Grundscheibe 14 ist an ihrer Stirnseite ferner mit einer Ausnehmung 45 versehen, welche einen in den Bereich der Grundscheibe 14 ragenden Abschnitt der Umfangspartie des Sternrades 33 aufnimmt, wobei die Form der Ausnehmung 45 dem Schwenkbereich des mit der Wickeltrommel 15 um die Achse 24 verschwenkbaren Sternrades 33 angepasst ist.As can be seen in particular from FIG. 3, three circular arc-shaped slots 41, 42 and 43 can be formed in the base plate 14, which are arranged offset to one another in the circumferential direction concentrically to the axis 24. In the slots 41, 42 and 43, the screws 26 engaging on the winding drum 15, each arranged in a guide sleeve 44, are guided, which corresponding pivotings of the winding drum) 15 about the axis 24 and thus different settings of the winding drum 15 transversely to the axis of rotation 8 on the base plate Allow 14. The base plate 14 is also provided on its end face with a recess 45 which receives a portion of the peripheral part of the star wheel 33 which projects into the region of the base plate 14, the shape of the recess 45 being the pivoting range of the star wheel which can be pivoted about the axis 24 with the winding drum 15 33 is adjusted.

An der Stirnseite der Grundscheibe 14 können zur Drehachse konzentrische Ringnuten ausgebildet oder, wie in den Fig. 2, 3,4 und 5 strichpunktiert angedeutet, entsprechende konzentrische Markierungskreise 46,46a, 46b, 46c angebracht sein, welche zum Führen bzw. zum erleichterten Einstellen der Umfangselemente 18 bezüglich der Grundscheibe 14 dienen.On the end face of the base plate 14 concentric annular grooves can be formed or, as indicated in FIGS. 2, 3, 4 and 5 by dash-dotted lines, corresponding concentric marking circles 46, 46a, 46b, 46c can be attached, which are for guiding or for easier adjustment the peripheral elements 18 serve with respect to the base plate 14.

Die Wickeltrommel 15 ist - bei gelösten Schrauben 26 - durch Verschwenken um die Achse 24 der Welle 25 gegenüber der feststehenden Grundscheibe 14 zwischen der in der Fig. 2 dargestellten, bezüglich der Drehachse 8 zentrischen Betriebsstellung und einer in der Fig. 5 dargestellten, bezüglich der Drehachse 8 exzentrischen Betriebsstellung 15" verstellbar, in welcher der an der Grundscheibe 14 anliegende Rand der Wickeltrommel 15 den entlang dem Rand der Grundscheibe 14 verlaufenden grössten Markierungskreis 46 berührt. Entsprechend sind die in den Schlitzen 41, 42, 43 geführten Schrauben 26 je zwischen der in der Fig. 3 dargestellten Stellung und einer Stellung 26" nach Fig. 5 verstellbar, so dass die Befestigung der Wickeltrommel 15 auch in jeder beliebigen, innerhalb des Schwenkbereichs liegenden exzentrischen Betriebsstellung gewährleistet ist. In der Fig. 4 ist eine mittlere Betriebsstellung 15' dargestellt, in welcher der Rand der Wickeltrommel 15 auf den kleineren Markierungskreis 46b eingestellt ist und die Schrauben 26 je eine entsprechende Stellung 26' einnehmen.The winding drum 15 is - with loosened screws 26 - by pivoting about the axis 24 of the shaft 25 relative to the fixed base plate 14 between the operating position shown in FIG. 2, central with respect to the axis of rotation 8, and one shown in FIG. 5, with respect to the Rotation axis 8 eccentric operating position 15 "is adjustable, in which the edge of the winding drum 15 resting on the base plate 14 touches the largest marking circle 46 running along the edge of the base plate 14. Accordingly, the screws 26 guided in the slots 41, 42, 43 are each between the in the position shown in FIG. 3 and a position 26 "according to FIG. 5 so that the fastening of the winding drum 15 is also ensured in any eccentric operating position lying within the swivel range. 4 shows a middle operating position 15 ', in which the edge of the winding drum 15 is set to the smaller marking circle 46b and the screws 26 each assume a corresponding position 26'.

Der Führungsbügel 20 ist am Gehäuse 2 mittels Schrauben 51 befestigt. Entsprechend der Darstellung in den Fig. 2,4 und 5 können die Schrauben 51 am Führungsbügel 20 in quer zum Umfang des Gehäuses 2 verlaufenden Schlitzen 52 angeordnet und am Gehäuse 2 in einem kreisbogenförmigen, zur Drehachse 8 konzentrischen Führungsschlitz 53 in Umfangsrichtung verstellbar und feststellbar geführt sein. Der Führungsbügel 20 kann somit in jeder Betriebsstellung 15' bzw. 15" der Wickeltrommel 15 in einer entsprechenden Betriebsstellung 20' bzw. 20" eingestellt werden, wodurch das Sternrad 33 in der jeweiligen Betriebsstellung 33' bzw. 33" seitlich geführt und die Wickeltrommel 15 gegen Drehung gesichert wird.The guide bracket 20 is attached to the housing 2 by means of screws 51. As shown in FIGS. 2, 4 and 5, the screws 51 can be arranged on the guide bracket 20 in slots 52 extending transversely to the circumference of the housing 2 and guided in the circumferential direction on the housing 2 in a circular arc-shaped guide slot 53 concentric with the axis of rotation 8 and can be locked be. The guide bracket 20 can thus be set in a corresponding operating position 20 'or 20 "in each operating position 15' or 15" of the winding drum 15, whereby the star wheel 33 is laterally guided in the respective operating position 33 'or 33 "and the winding drum 15 is secured against rotation.

In der Betriebsstellung nach den Fig. 1 und 2 weist der Wickelkörper 13 den durch den Durchmesser der zur Drehachse 8 konzentrisch eingestellten Wickeltrommel 15 gegebenen kleinsten Wickeldurchmesser auf.

Entsprechend sind die Enden der Umfangselemente 18 in der Betriebsstellung nach Fig. 4 auf den Markierungskreis 46b, und in der Betriebsstellung nach Fig. 5 auf den grössten Markierungskreis 46 eingestellt. Auf diese Weise lässt sich der Wickeldurchmesser des Wickelkörpers 13 und damit die jeweils zu speichernde Fadenlänge sehr genau an unterschiediiche, z. B. durch die Beschaffenheit des zu verarbeitenden Fadenmaterials und - bei Webmaschinen - durch die Breite des herzustellenden Gewebes gegebene Betriebserfordernisse anpassen.In the operating position according to FIGS. 1 and 2, the winding body 13 has the smallest winding diameter given by the diameter of the winding drum 15 set concentrically with the axis of rotation 8. By pivoting the winding drum 15 about the axis 24 and corresponding radial adjustments of the carrier parts 18a of the circumferential elements 18 to a large circle concentric with the axis of rotation 8, which touches the circumferential part of the winding drum 15 that is the most distant from the axis of rotation 8, larger, corresponding to the respective large circle can The winding diameter can be set, the thread windings being essentially concentric to the axis of rotation 8 in each pivoting position of the winding drum 15. Correspondingly, the ends of the peripheral elements 18 are set to the marking circle 46b in the operating position according to FIG. 4 and to the largest marking circle 46 in the operating position according to FIG. 5. In this way, the winding diameter of the winding body 13 and thus the thread length to be stored in each case can be very precisely matched to different, e.g. B. by the nature of the thread material to be processed and - given weaving machines - by the width of the fabric to be manufactured given operational requirements.

Entsprechend der Darstellung nach Fig. 6 kann die Wickeltrommel 15 auch auf einer mit dem Maschinenantrieb gekoppelten drehbaren Grundscheibe 14a quer zur Drehachse 8 verstellbar befestigt sein. Die Grundscheibe 14a, die Wickeltrommel 15 und die Umfangselemente 18 bilden somit einen um die Drehachse 8 drehbaren Wickelkörper 13a. dem der Schussfaden 12 tangential zugeführt wird. Entsprechend kann die die Drehachse 8 bildende Welle 22 gegen Drehung gesichert sein. Der Wickelkörper 13a kann von einem konzentrisch zur Drehachse 8 angeordneten Ballonbrecher 55 umgeben sein, der einen beim Abziehen des Schussfadens 12 von der rotierenden Fadenwicklung entstehenden Fadenballon 56 begrenzt.6, the winding drum 15 can also be fixed adjustably transversely to the axis of rotation 8 on a rotatable base plate 14a coupled to the machine drive. The base plate 14a, the winding drum 15 and the peripheral elements 18 thus form a winding body 13a which can be rotated about the axis of rotation 8. that of Weft thread 12 is fed tangentially. Accordingly, the shaft 22 forming the axis of rotation 8 can be secured against rotation. The winding body 13a can be surrounded by a balloon breaker 55 which is arranged concentrically with the axis of rotation 8 and which delimits a thread balloon 56 which is formed when the weft thread 12 is pulled off the rotating thread winding.
