Die Erfindung betrifft eine Anordnung zum Halten von kammartig angeordneten Schussfadeneintragselementen umfassend erste und zweite Elemente sowie Luftdüsen, die den zweiten Elementen zugeordnet sind, welche Anordnung einen Tragkörper aufweist, in welchem die Eintragselemente in einer vorbestimmten Zuordnung angeordnet sind mit mindestens ein Halteorgan für die ersten und zweiten Elemente, das im Tragkorper angeordnet ist, und eine Webmaschine mit einer solchen Anordnung.The invention relates to an arrangement for holding comb-like weft insertion elements comprising first and second elements as well as air vents that which arrangement are assigned to the second elements has a support body in which the Entry elements in a predetermined assignment are arranged with at least one holding member for the first and second elements, which is arranged in the supporting body, and a weaving machine with such an arrangement.
Zur pneumatischen Schussfadeneintragung werden bekanntlich Führungselemente und Stafettendüsen verwendet. Die Elemente und Düsen sind in einer vorbestimmten Zuordnung angeordnet und in dieser Zuordnung an einem Tragorgan montiert.For pneumatic weft insertion as is known, guide elements and relay nozzles used. The elements and nozzles are in one predetermined assignment arranged and in this Assignment mounted on a support element.
In der EP-A-0 196 349 ist ein Webrotor mit Schusseintragkämme beschrieben. Die Kämme umfassen einen Halter und Schussfadeneintragelemente in Form von Lamellen. Der Halter weist eine Nut auf, in welcher die Lamellen mittels einer Silikonmasse gehalten sind.In EP-A-0 196 349 a weaving rotor is included Weft insertion combs described. The combs encompass one Holders and weft insertion elements in the form of Slats. The holder has a groove in which the Slats are held by means of a silicone compound.
Die Nachteile einer derartigen Anordnung sind im wesentlichen darin zu sehen, dass das Ersetzen von beschädigten Teilen sehr aufwendig ist und dass bei einer Musteränderung und der daraus folgenden Kettrapportänderung ein kompletter Austausch der Eintragselemente erforderlich ist, was einen bedeutenden Aufwand zur Folge hat.The disadvantages of such an arrangement are in essential to see that replacing damaged parts is very complex and that with a Pattern change and the consequent Chain repeat change a complete exchange of the Entry elements are required, which is a significant Effort.
Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung zum Halten von Schussfadeneintragselementen zu schaffen, bei der die Elemente austauschbar und die Luftdüsen auf die zugeordneten Elemente ausrichtbar sind.The invention has for its object an arrangement to create weft insertion elements, where the elements are interchangeable and the air vents on the assigned elements can be aligned.
Diese Aufgabe wird erfindungsgemäss gelöst, durch mindestens einen Halter für die Luftdüsen, der im Tragkörper angeordnet ist und aus einem elastisch verformbaren Material besteht, um den Abstand zwischen den Luftdüsen zu verändern und die Luftdüsen auf die zweiten Elemente auszurichten.According to the invention, this object is achieved by at least one holder for the air nozzles, which in the Support body is arranged and made of an elastic deformable material is made up of the distance between to change the air nozzles and the air nozzles on the align second elements.
Bei dieser Anordnung sind lediglich die ersten und zweiten Elemente zu entfernen, das Halteorgan auszutauschen, die Elemente wieder einzusetzen und die Luftdüsen auf die zweiten Elemente auszurichten, um die Eintragselemente an den neuen Kettrapport anzupassen.In this arrangement, only the first and second elements to remove the holding member replace, replace the elements and the Align air vents to the second elements to make the Adjust entry elements to the new warp repeat.
Durch die kraftschlüssige Verbindung der ersten und zweiten Elemente und des Halters mit dem Tragkörper, kann in vorteilhafter Weise nach dem Wechsel bzw. der Aenderung der Eintragselemente deren Zuordnung und Abstände gewährleistet werden.Through the frictional connection of the first and second elements and the holder with the support body, can advantageously after the change or Change the entry elements their assignment and Distances are guaranteed.
