Description

Die Erfindung betrifft ein endloses Garntraversierband für eine Garntraversiervorrichtung an einer Kreuzspulen herstellenden Maschine, das in Abständen mit Garnmitnehmern versehen ist, die an der Schmalseite des Garntraversierbandes angeordnet sind und die Form eines Sägezahns haben, und Verfahren zu seiner Herstellung.The invention relates to an endless yarn traversing belt for a yarn traversing device on a machine producing cross-wound bobbins, which is provided at intervals with yarn carriers, which are arranged on the narrow side of the yarn traversing belt and have the shape of a sawtooth, and a method for producing the same.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Garntraversierband so zu verbessern, daß es besonders gut zum Garntraversieren geeignet wird, sich leicht herstellen läßt, einem geringen Verschleiß unterliegt und mit einer einfachen, preiswerten Antriebsvorrichtung betrieben werden kann.The invention has for its object to improve a generic yarn traversing belt so that it is particularly well suited for yarn traversing, can be easily manufactured, is subject to low wear and can be operated with a simple, inexpensive drive device.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß das Garntraversierband aus in gummielastisches Material eingebettetem Gewebe aus Textil- und/oder Metallfäden besteht und daß die Vorderflanken der Garnmitnehmer eine hülsenartige Armierung aus verschleißfestem Werkstoff aufweisen.According to the invention, this object is achieved in that the yarn traversing belt consists of fabric embedded in rubber-elastic material made of textile and / or metal threads and that the front flanks of the yarn drivers have a sleeve-like reinforcement made of wear-resistant material.

Vorteilhafte Weiterbildungen der Erfindung sind in den Ansprüchen 2 bis 9 beschrieben.Advantageous developments of the invention are described in claims 2 to 9.

Ein neues und erfinderisches Verfahren zum Herstellen eines im Oberbegriff des Anspruchs 1 beschriebenen Garntraversierbandes ist dadurch gekennzeichnet, daß aus Textil- und/oder Metallfäden ein Gewebe hergestellt, das Gewebe, gegebenenfalls mehrlagig, in gummielastisches Material eingebettet und aus einem bandförmigen Streifen des so erhaltenen Gebildes Teile ausgestanzt werden, so daß die Garnmitnehmer stehenbleiben, und anschließend die Vorderflanken der Garnmitnehmer mit hülsenartigen Armierungen versehen werden.A new and inventive method for producing a yarn traversing belt described in the preamble of claim 1 is characterized in that a fabric is made from textile and / or metal threads, the fabric, optionally multi-layered, in rubber-elastic Embedded material and parts are punched out of a band-shaped strip of the structure thus obtained, so that the yarn carriers remain, and then the front flanks of the yarn carriers are provided with sleeve-like reinforcements.

Ein alternatives Verfahren zum Herstellen eines endlosen Garntraversierbandes nach dem Oberbegriff des Patentanspruchs 1 ist dadurch gekennzeichnet, daß aus Textil- und/oder Metallfäden ein Gewebe hergestellt, mehrere Lagen des Gewebes aufeinandergelegt und dazwischen biegsame Garnmitnehmer eingelegt werden, das Ganze dann in gummielastisches Material eingebettet wird und anschließend die Vorderflanken der Garnmitnehmer mit hülsenartigen Armierungen versehen werden.An alternative method for producing an endless yarn traversing belt according to the preamble of claim 1 is characterized in that a fabric is made from textile and / or metal threads, several layers of the fabric are placed on top of one another and flexible yarn carriers are inserted in between, and the whole is then embedded in rubber-elastic material and then the front flanks of the yarn carriers are provided with sleeve-like reinforcements.

In Weiterbildung der Erfindung ist vorgesehen, daß das Garntraversierband an beiden Enden angeschäftet wird und daß dann die beiden Enden überlappt miteinander verklebt, verschweißt oder aneinandervulkanisiert werden.In a further development of the invention it is provided that the yarn traversing belt is bought at both ends and that the two ends are then overlapped, glued, welded or vulcanized to one another.

In Weiterbildung der Erfindung ist vorgesehen, daß die Mehrlagigkeit der Gewebekarkasse durch Aufwickeln des Gewebes über einen Kern zustandegebracht wird.In a further development of the invention it is provided that the multilayer of the tissue carcass is brought about by winding the tissue over a core.

Die verhältnismäßig steile, maximal etwa 10 Grad entgegen der Bandlaufrichtung aus der Senkrechten geneigte Vorderflanke der Garnmitnehmer gewährleistet eine gute Mitnahme des Garns beim Traversieren und behindert zugleich noch nicht die Abgabe des Garns an den Umkehrstellen der Traversierung.The relatively steep front flank of the yarn drivers, which is inclined from the vertical from the vertical at a maximum of about 10 degrees, ensures good yarn entrainment when traversing and at the same time does not hinder the delivery of the yarn at the reversal points of the traversing.

Ein konvexer oder konvex gebrochener Verlauf der Rückflanke des Garnmitnehmers gewährleistet die erforderliche Stabilität und verhindert das Hängenbleiben des Garns an der Rückseite des Garnmitnehmers.A convex or convex broken course of the back flank of the yarn carrier ensures that required stability and prevents the yarn from getting caught on the back of the yarn carrier.

Das Ausrunden der Übergänge zwischen Garntraversierband und Garnmitnehmern gewährleistet eine lange Haltbarkeit und verhindert Ermüdungsbrüche, indem das Eintreten einer Kerbwirkung so gut wie ausgeschlossen ist.The rounding of the transitions between the yarn traversing belt and the yarn drivers ensures long durability and prevents fatigue breaks by virtually eliminating the occurrence of a notch effect.

Eine hülsenartige Armierung der Vorderflanke des Garnmitnehmers ist besonders einfach, wirtschaftlich und haltbar. Eine solche Ausbildung der Armierung beeinträchtigt auch nicht nennenswert die Flexibilität des Garntraversierbandes, dies insbesondere dann nicht, wenn die Armierung aus einer einen Längsschlitz aufweisenden, federnden Hülse besteht, die durch ihre Federkraft, die Vorderflanke übergreifend, kraftschlüssig mit dem Garnmitnehmer verbunden ist. Es besteht dann lediglich ein Linienkontakt mit dem Garnmitnehmer. Derartige Hülsen sind auf anderen Gebieten der Technik bereits als sogenannte Spannhülsen oder Spannstifte in Gebrauch, so daß diese Normteil e hier mit Vorteil verwendet werden können.A sleeve-like reinforcement of the front flank of the yarn driver is particularly simple, economical and durable. Such a design of the reinforcement also does not significantly impair the flexibility of the yarn traversing belt, particularly if the reinforcement consists of a resilient sleeve having a longitudinal slot, which is connected to the yarn driver in a force-locking manner by its spring force, spanning the front flank. Then there is only a line contact with the yarn driver. Such sleeves are already in use in other fields of technology as so-called adapter sleeves or dowel pins, so that these standard parts e can be used here with advantage.

Beim Herstellen des Garntraversierbandes kann man von einer plattenförmigen oder von einer bandförmigen Karkasse ausgehen. Fertig vulkanisierte Platten können beispielsweise erst zu Bändern zerschnitten werden, und danach können die Garnmitnehmer durch Ausstanzen hergestellt werden. Bandförmige Karkassen sind beispielsweise durch Aufwickeln herstellbar, so daß ein nachträgliches Anschäften und Kleben, Schweißen oder Vulkanisieren entfällt. Dafür ist aber das Einbetten der Karkasse in gummielastisches Material nur mit Sondervorrichtungen möglich. Somit haben beide Zweige der Herstellung ihre Vor- und Nachteile.When manufacturing the yarn traversing belt, one can start from a plate-shaped or from a belt-shaped carcass. Fully vulcanized plates can first be cut into strips, for example, and then the yarn carriers can be produced by punching out. Band-shaped carcasses can be produced, for example, by winding them up, so that subsequent roughening and gluing, welding or vulcanizing is not necessary. However, embedding the carcass in rubber-elastic material is only possible with special devices. So both branches of production have their advantages and disadvantages.

In den Fig. 1 und 2 ist die Garntraversiervorrichtung einer Kreuzspulen herstellenden Maschine insgesamt mit (1) bezeichnet. Das Garn (2) wird mit Hilfe der Garntraversiervorrichtung (1) in Richtung des Pfeils (3) einer rotierenden Kreuzspule (4) zugeführt und dort in Kreuzlagen aufgewickelt. Hierzu traversiert die Garntraversiervorrichtung (1) das Garn (2) ständig in Richtung des Doppelpfeils (5). Zum Traversieren wird ein endloses Garntraversierband (6) verwendet. Das Garntraversierband (6) umschlingt die Rollen (7 bis 12), von denen die Rolle (8) einen Antriebsmotor (13) besitzt. Alle sechs Rollen sind an einem Tragkörper (15) gelagert. Der Tragkörper (15) trägt auch eine Garnleitplatine (14). Die Garnleitplatine (14) besitzt eine Garnleitkontur (16), die zu den Enden des Traversierbereichs hin einen ansteigenden Verlauf nimmt, wie es Fig. 2 zeigt.1 and 2, the yarn traversing device of a machine producing cross-wound bobbins is designated as a whole by (1). The yarn (2) is fed with the help of the yarn traversing device (1) in the direction of the arrow (3) to a rotating cheese (4) and wound up there in layers. For this purpose, the yarn traversing device (1) constantly traverses the yarn (2) in the direction of the double arrow (5). An endless yarn traversing belt (6) is used for traversing. The yarn traversing belt (6) wraps around the rollers (7 to 12), of which the roller (8) has a drive motor (13). All six rollers are mounted on a support body (15). The support body (15) also carries a yarn guide plate (14). The yarn guide plate (14) has a yarn guide contour (16) which increases towards the ends of the traversing area, as shown in FIG. 2.

Das Garntraversierband (6) ist in Abständen mit drei Garnmitnehmern (17, 18, 19) versehen. Alle drei Garnmitnehmer sind an der Schmalseite des Garntraversierbandes angeordnet und haben die Form eines Sägezahns.The yarn traversing belt (6) is provided with three yarn carriers (17, 18, 19) at intervals. All three yarn drivers are arranged on the narrow side of the yarn traversing belt and have the shape of a sawtooth.

Die Vorderflanken der Garnmitnehmer (17 bis 19) weisen in Laufrichtung (20) des Garntraversierbandes (6) und sind mit je einer hülsenartigen Armierung (21) aus verschleißfestem Werkstoff versehen.The front flanks of the yarn carriers (17 to 19) point in the running direction (20) of the yarn traversing belt (6) and are each provided with a sleeve-like reinforcement (21) made of wear-resistant material.

Gemäß Fig. 2 wandert der Garnmitnehmer (17) gerade nach links. Er nimmt dabei das Garn (2) mit, das an der Garnleitkontur (16) der Garnleitplatine (14) entlangrutscht, bis der Garnmitnehmer (17) hinter der ansteigenden Garnleitkontur (16) wegtaucht und das Garn (2) freigibt, das dann durch den von links nach rechts wandernden Garnmitnehmer (18) erfaßt und anschließend von links nach rechts traversiert wird, bis das Garn dann anschließend durch den dritten Mitnehmer (19) erfaßt wird, der es dann wieder von rechts nach links traversiert und so fort.2, the yarn driver (17) moves straight to the left. He takes the yarn (2) with him, which slips along the yarn guide contour (16) of the yarn guide plate (14) until the yarn driver (17) dips behind the rising yarn guide contour (16) and releases the yarn (2), which is then released by the yarn driver (18) traveling from left to right and then traversed from left to right until the yarn is then captured by the third driver (19), which then traverses it again from right to left and so on.

In Fig. 1 sind die Garnmitnehmer (17 bis 19) der einfacheren Darstellung wegen lediglich durch Punkte dargestellt.
Das Garntraversierband (6) besteht aus in gummielastisches Material eingebettetem Gewebe aus Textilfäden. Alternativ können in dieses Textilgewebe auch Metallfäden eingewebt sein, vorzugsweise in Bandlaufrichtung.In Fig. 1, the yarn carriers (17 to 19) are shown for the sake of simplicity only by dots.
The yarn traversing belt (6) consists of fabric made of textile threads embedded in rubber-elastic material. Alternatively, metal threads can also be woven into this textile fabric, preferably in the direction of tape travel.

Fig. 2 zeigt, daß die steile Flanke der Garnmitnehmer (17 und 18) senkrechtstehend zum Garntraversierband (6) angeordnet ist. Dasselbe gilt für den Garnmitnehmer (19).Fig. 2 shows that the steep flank of the yarn carriers (17 and 18) is arranged perpendicular to the yarn traversing belt (6). The same applies to the thread driver (19).

Bei der Alternativausbildung des Garntraversierbandes (6ʹ) nach den Fig. 3 und 4 hat die Rückenflanke (22, 22ʹ) des Garnmitnehmers (18ʹ) einen konvex gebrochenen Verlauf. Die Rückenflanke (22) verläuft vom Ende (23ʹ) der Vorderflanke (23) aus unter einem Winkel Beta von etwa 10 Grad gegen das Garntraversierband (6ʹ) geneigt. Nach Richtungsänderung verläuft die Rückenflanke (22) dann stärker geneigt.In the alternative embodiment of the yarn traversing belt (6ʹ) according to FIGS. 3 and 4, the back flank (22, 22ʹ) of the yarn driver (18ʹ) has a convex broken course. The back flank (22) extends from the end (23ʹ) of the front flank (23) at an angle Beta of approximately 10 degrees towards the yarn traversing belt (6ʹ). To The back flank (22) then changes its direction more inclined.

Insbesondere Fig. 3 läßt erkennen, daß die Übergänge zwischen Garntraversierband (6ʹ) und Garnmitnehmer (18ʹ) ausgerundet sind.3 shows in particular that the transitions between the yarn traversing belt (6ʹ) and the yarn driver (18mit) are rounded.

Bei diesem Ausführungsbeispiel besteht die Armierung (24) aus einer einen Längsschlitz aufweisenden, federnden Hülse, die durch ihre Federkraft, die Vorderflanke (23) übergreifend, kraftschlüssig mit dem Garnmitnehmer (18ʹ) verbunden ist. Diese Hülse (24) besteht aus rostgeschütztem Stahl.In this exemplary embodiment, the reinforcement (24) consists of a resilient sleeve having a longitudinal slot, which is connected to the yarn driver (18,) by means of its spring force, spanning the front flank (23). This sleeve (24) is made of rustproof steel.

Während die Vorderflanke (23) des Garnmitnehmers (18ʹ) nach dem Ausführungsbeispiel gemäß Fig. 3 und 4 senkrecht stehend zum Garntraversierband (6ʹ) angeordnet ist, liegt die durch eine Hülse (24ʹ) armierte Vorderflanke (23ʹ) des Garnmitnehmers (18ʺ) des Garntraversierbandes (6ʺ) bei dem Ausführungsbeispiel nach Fig. 5 unter einem Winkel Alpha von etwa 10 Grad entgegen der Bandlaufrichtung aus der Senkrechten geneigt. Bei dem Garnmitnehmer (18ʺ) hat die Rückenflanke (22ʹ) einen konvexen Verlauf.3 and 4 is arranged vertically to the yarn traversing belt (6ʹ), the front flank (23ʹ) of the yarn driver (18ʺ) of the yarn traversing belt is reinforced by a sleeve (24ʹ) (6ʺ) in the embodiment of FIG. 5 inclined at an angle alpha of about 10 degrees against the tape running direction from the vertical. The back flank (22ʹ) of the yarn driver (18ʺ) has a convex shape.

Die Garntraversierbänder (6 und 6ʺ) wurden folgendermaßen angefertigt:The yarn traversing tapes (6 and 6ʺ) were made as follows:

Zuerst wurde aus Textilfäden ein Gewebe hergestellt, das mehrlagig zunächst provisorisch aufgewickelt wurde. Die aufeinanderliegenden Lagen wurden dann wieder vom Wickelkörper abgezogen, durch ein Gummierungsbad geleitet und anschließend automatisch vulkanisiert, so daß ein zugfestes, in Zugrichtung dehnungsarmes, elastisches Band entstand. Dieses Band wurde dann in mehrere Bänder aufgeteilt, und aus jedem dieser Bänder wurden zunächst Traversierbandrohlinge dadurch hergestellt, daß man durch Ausstanzen die Garnmitnehmer bildete. Der Traversierbandrohling wurde an beiden Enden angeschäftet, und die Enden wurden dann überlappt zusammenvulkanisiert. Anschließend erhielten die drei Garnmitnehmer ihre Armierungen.First, a fabric was made from textile threads, which was initially provisionally wound up in several layers. The layers lying one on top of the other were then pulled off the winding former, passed through a rubber coating bath and then automatically vulcanized, so that a tensile, elastic, low-stretching band was produced. This band was then divided into several bands, and each of these bands initially became Traversierbandrohlinge manufactured in that the yarn carriers were formed by punching out. The traversing tape blank was piled up at both ends, and the ends were then vulcanized together overlapping. Then the three yarn carriers received their reinforcements.

Hiervon abweichend, wurde das Garntraversierband (6ʹ) folgendermaßen hergestellt:Deviating from this, the yarn traversing belt (6ʹ) was produced as follows:

Zunächst wurde aus Textilfäden ein Gewebeband hergestellt und provisorisch aufgewickelt. Dann wurde das Band auf eine Trommel gewickelt, die die Umfangslänge des späteren Garntraversierbandes hatte. Auf diese Trommel wurden vier Lagen des Gewebebandes aufgewickelt und dann wurden zwischen die Lagen die in Fig. 3 angedeuteten Füße (25) des Garnmitnehmers (18ʹ) und der übrigen Garnmitnehmer eingeschoben. Die Garnmitnehmer bestehen hier aus biegsamem Material. Das Ganze wurde dann auf der Trommel gummiert und vulkanisiert und nach dem Vulkanisieren von der Trommel abgezogen. Anschließend wurden die Armierungen (24ʹ) aufgesteckt. First, a fabric tape was made from textile threads and provisionally wound up. Then the tape was wound on a drum, which had the circumferential length of the later yarn traversing tape. Four layers of the fabric tape were wound onto this drum and then the feet (25) of the thread catcher (18ʹ) and the other thread catchers indicated in FIG. 3 were inserted between the layers. The thread carriers are made of flexible material. The whole was then gummed and vulcanized on the drum and peeled off the drum after vulcanization. The reinforcements (24ʹ) were then attached.
