Description
Die Erfindung betrifft einen Fadenführerarm mit Fadenleitorganen, die ohne Spaltbildung auf einem Fadenabhalteschild angeordnet sind. Ein solcher Fadenführerarm ist aus der DE-PS 37 32 879 der Anmelderin bekannt. Der Fadenabhalteschild verhindert, daß sich eine Fadenschlaufe um ein Fadenleitorgan herumlegen kann.The invention relates to a thread guide arm with thread guide elements, the one with no gap formation on a thread holding plate are arranged. Such a thread guide arm is from the DE-PS 37 32 879 of the applicant known. The thread stop sign prevents a thread loop around a thread guide can lay around.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den bekannten Fadenführerarm derart weiterzubilden, daß die Fertigung der Fadenleitorgane vereinfacht wird und die Fadenleitorgane rasch auf unterschiedliche Fadenarten und -stärken anpaßbar sind.The present invention has for its object the known Thread guide arm in such a way that the production the thread guide is simplified and the thread guide quickly on different thread types and strengths are customizable.
Die Aufgabe wird mit einem Fadenführerarm der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß die Fadenleitorgane als Ösen ausgebildet und austauschbar in mindestens einem auf dem Fadenabhalteschild angeordneten Aufnahmekörper eingesetzt sind. Bei einer derartigen Ausgestaltung können der oder die Aufnahmekörper und der Fadenabhalteschild aus einem einstückigen Gußteil gefertigt werden, wobei das arbeitsaufwendige Entgraten der Öffnungen des Aufnahmekörpers entfallen kann, da als Gleitflächen für die Fäden nicht der Aufnahmekörper sondern die in diesen einsetzbaren Ösen dienen. Diese Einzelösen können sehr viel einfacher gratfrei hergestellt werden. Die austauschbare Anordnung der Ösen hat zudem den Vorteil, daß diese gegen andere, aus unterschiedlichem Material bestehende und mit einem unterschiedlichen Durchmesser versehene Ösen ersetzt werden können, sofern dies die Fadenart und -stärke erfordert. Eine rasche Verbindung zwischen Ösen und Aufnahmekörper kann dadurch erzielt werden, daß die Ösen in den Aufnahmekörper einrastbar sein können. Die Ösen können hierzu auch durch Öffnungen im Fadenabhalteschild in den Aufnahmekörper einsetzbar sein, wobei die Öffnungen nach Befestigung des Fadenabhalteschildes auf den Fadenführerarm durch diesen mindestens teilweise abgedeckt sind. Ein Einführen der Ösen von der Rückseite des Fadenabhalteschildes in den Aufnahmekörper bietet die Möglichkeit einer automatischen Bestückung des Bauelements mit den Ösen. Anschließend kann der Fadenabhalteschild mit dem Fadenführerarm beispielsweise verschraubt werden. Durch die teilweise Abdeckung der Öffnungen durch den Fadenführerarm ist sichergestellt, daß die Ösen sich nicht selbsttätig aus dem Aufnahmekörper lösen können. Die Ösen können dabei aus einem anderen Material gefertigt sein als der Aufnahmekörper und/oder der Fadenabhalteschild. Für eine Anpassung der Fadenführerarme an unterschiedliche Garnarten und -stärken ist also nur das Zur-Verfügung-Stellen von Ösen aus unterschiedlichen Materialien erforderlich, während alle anderen Elemente des Fadenführerarms unverändert bleiben können. Als Materialien für die Ösen kommen Keramik, Kunststoff oder Metall infrage.The task is carried out with a thread guide arm of the type mentioned Art solved according to the invention in that the thread guide designed as eyelets and interchangeable in at least a receiving body arranged on the thread holding plate are used. With such a configuration, the or the receiving body and the thread-holding shield from one one-piece casting are made, the laborious Deburring the openings of the receiving body is not necessary can, since the sliding body for the threads is not the receiving body but the serve in these eyelets. This Single eyelets can be manufactured much more easily without burrs become. The interchangeable arrangement of the eyelets also has the Advantage that these against others, made of different materials existing and with a different diameter provided eyelets can be replaced, provided that this is the thread type and strength required. A quick connection between eyelets and receiving body can be achieved in that the eyelets can be snapped into the receiving body. The eyelets can also through openings in the thread holding plate in the Receiving body can be used, the openings after Attachment of the thread holding plate to the thread guide arm are at least partially covered by this. An introduction of the eyelets from the back of the thread holding plate in the receiving body offers the possibility of automatic Equipping the component with the eyelets. Then the Thread holding plate with the thread guide arm, for example be screwed. By partially covering the openings the thread guide arm ensures that the Eyes do not come loose from the holder body automatically can. The eyelets can be made of a different material be made as the receiving body and / or the thread holding plate. For adapting the thread guide arms to different ones Yarn types and strengths are therefore only made available of eyelets made of different materials required while all other elements of the thread guide arm can remain unchanged. As materials for the eyelets ceramic, plastic or metal are possible.

Fig. 1 zeigt einen Fadenabhalteschild 10 mit einer nahezu
kreisförmigen Umrandung. Auf diesem Fadenabhalteschild sind
drei Fadenleitorgane 11, 12 und 13 angeordnet, die von einem
sternförmigen Aufnahmekörper 14 gebildet werden, der jeweils
an seinen Armen mit Aussparungen 15 (Fig. 3) zur Aufnahme von
Ösen 16 versehen ist. Der Aufnahmekörper 14 weist außerdem
eine zentrale Bohrung 17 zur Aufnahme einer Schraube zu seiner
Verbindung mit einem Fadenführerarm auf.Fig. 1 shows a
Aus der Ansicht nach Fig. 2 ist zu erkennen, daß der Fadenabhalteschild
10 jeweils unter den Armen des Aufnahmekörpers
14 Öffnungen 18 zum Einführen der Ösen 16 in die Aussparungen
15 im Aufnahmekörper 14 aufweist. Die Form der
Öffnungen 18 ist dabei der Form der Ösen 16 angepaßt. In
Fig. 3 ist ein Schnitt durch eines der Fadenleitorgane 11
dargestellt. Hieraus ist ersichtlich, daß die Öse 16 formschlüssig
in die Aussparung 15 des Aufnahmekörpers 14 paßt.
Die Öse 16 weist eine zentrale Öffnung 19 zum Durchführen
eines Fadens auf. Sie wird in der Aussparung 15 durch zwei
dort angeordnete Rastnasen 20 festgehalten. Diese Rastnasen 20
greifen in entsprechend geformte Vertiefungen 21 (Fig. 4)
senkrecht zur Umfangsrichtung der Öse 16 ein und bilden eine
Rastverbindung, die jedoch auf einfache Weise wieder lösbar
ist, wodurch die Ösen 16 leicht austauschbar im Aufnahmekörper
14 angeordnet sind. Die Öffnung 19 der Öse 16 weist einen
sich von innen beidseitig nach außen erweiternden Querschnitt
auf. Hierdurch werden scharfe Kanten vermieden, die einen zu
großen Fadenabrieb erzeugen würden. Auch der Außendurchmesser
weitet sich beidseitig nach außen hin und endet in Wulsten 22
und 23. Dazwischen ist ein Bereich 24 geringeren Durchmessers
angeordnet, in den ein vorspringender Bereich in der Aussparung
15 des Aufnahmekörpers 14 eingreift und so ein Lösen der
Öse 16 in axialer Richtung aus der Aussparung 15 verhindert.
Nach dem Festschrauben des Fadenabhalteschildes 10 auf einem
Fadenführerarm, der die Öffnungen 18 des Schildes 10 von der
Unterseite her mindestens teilweise abdeckt, ist dadurch ein
unbeabsichtigtes selbsttätiges Herauslösen der Ösen 16 aus dem
Aufnahmekörper 14 unmöglich. Sollen die Ösen 16 gegen andere,
aus einem anderen Material bestehende oder mit einem anderen
Durchmesser versehene Ösen ausgetauscht werden, so werden
einfach der Fadenabhalteschild 10 wieder vom Fadenführerarm
abgeschraubt, die Ösen mit Hilfe eines in die Durchgangsöffnungen
19 eingreifenden Werkzeugs aus der Rastverbindung
gelöst, durch die Öffnungen 18 aus dem Aufnahmekörper 14
herausgenommen und anschließend die neuen Ösen 16 in die Aussparung
15 des Aufnahmekörpers 14 eingerastet.From the view according to FIG. 2 it can be seen that the
