Auf der Fangseite einer Webmaschine sind in Schussrichtung einem Webblatt 1 mit einem Führungskanal 2 für einen Schussfaden, ein Schussfadenwächter 3 und eine Vorrichtung 4 der hier in Rede stehenden Art nachgeordnet.A weaving reed 1 with a guide channel 2 for a weft thread, a weft thread monitor 3 and a device 4 of the type in question are arranged downstream of the weaving direction on the catch side of a weaving machine.
Es wird auf die Figuren 2 bis 4 Bezug genommen. Wie die Fig. 4 zeigt, enthält die Vorrichtung 4 einen Düsenhalter 5 und eine Düse 6, die am Düsenhalter montiert ist. Der Düsenhalter 5 hat eine Durchbohrung 8, die einen Kanal zur Aufnahme eines Schussfadens 9 bildet und einen Ansatz 10, der eine geschlitzte Bohrung zur Aufnahme der Düse 6 aufweist. Die Düse 6 besteht aus einen Körper 11, der einen rechteckähnlichen Querschnitt mit parallelen Längsseiten und gerundeten Schmalseiten (Fig.2) und einen zylindrischen Ansatz 12 aufweist. In der Düse sind eine Blindbohrung 13 und zwei Düsenlöcher 14 ausgebildet, die parallel zueinander angeordnet und in der gerundetenReference is made to FIGS. 2 to 4. As shown in FIG. 4, the device 4 contains a nozzle holder 5 and a nozzle 6 which is mounted on the nozzle holder. The nozzle holder 5 has a through hole 8, which forms a channel for receiving a weft thread 9 and an extension 10, which has a slotted hole for receiving the nozzle 6. The nozzle 6 consists of a body 11, which has a rectangular cross section with parallel long sides and rounded narrow sides (FIG. 2) and a cylindrical extension 12. A blind bore 13 and two nozzle holes 14 are formed in the nozzle, which are arranged parallel to one another and in the rounded one
Seite ausmünden. Die Düse ist im Halter drehbar montiert und durch eine nicht dargestellte Schraube gesichert. Dadurch wird eine halboffene Ausnehmung 15 gebildet, welche mit dem Führungskanal 2 fluchtet. Die Düse 6 ist mit einer Leitung 16 zum Zuführen von Luft verbunden. In der Fig.2 ist die Düse 6 in einer Stellung gezeigt, in welcher analog zum Stand der Technik die Düsenlöcher mit dem Kanal fluchten. Aufgrund der sich schneidenden Luftstrahlen treten die bekannten Probleme auf. Ist der Förderluftstrom für den Schussfaden stärker als Luftstrom aus der Düse 6, so wird der Schussfaden 9 nicht korrekt abgelenkt und gespannt. Ist der Luftstrom aus der Düse 6 stärker, so wird der Förderluftstrom für den Schussfaden bereits vor Erreichen der Vorrichtung abgelenkt. Somit sind die sich schneidenden Luftstöme aufeinander abzustimmen, was sehr aufwendig ist. Bei der ersten Ausführungsform der Vorrichtung wird in vorteilhafter Weise diese Abstimmung der Luftströme durch Schwenken der Düse 6 und damit des erzeugten Luftvorhanges erleichtert ( Fig.3 ) .Open out side. The nozzle is rotatably mounted in the holder and secured by a screw, not shown. This forms a semi-open recess 15 which is aligned with the guide channel 2. The nozzle 6 is connected to a line 16 for supplying air. 2 shows the nozzle 6 in a position in which, analogously to the prior art, the nozzle holes are aligned with the channel. The known problems arise due to the intersecting air jets. If the conveying air flow for the weft thread is stronger than air flow from the nozzle 6, the weft thread 9 is not deflected and tensioned correctly. If the air flow from the nozzle 6 is stronger, the conveying air flow for the weft thread is deflected before reaching the device. This means that the intersecting air currents have to be coordinated, which is very complex. In the first embodiment of the device, this coordination of the air flows is advantageously facilitated by pivoting the nozzle 6 and thus the air curtain generated (FIG. 3).
Die Figuren 5 bis 7 zeigen eine zweite Ausführungsform der Vorrichtung. Wie Fig.7 zeigt ist bei dieser Vorrichtung ein Düsenhalter 21 in einen Grundkörper 22 mit dem Kanal 8 und ein plattenförmiges Halteelement 23 für die Düse 6 unterteilt. Das Halteelement 23 ist mit der geschlitzten Bohrung versehen, in welcher die Düse 6 angeordnet ist und mittels einer Schraube 26 am Grundkörper zu befestigen. Wie die Fig. 7 zeigt, ist das Halteelement 23 so angeordnet, dass einerseits die halboffene Ausnehmung 15 gebildet wird und andererseits die Düsenmündungen der Düse 6 mit der Mündung des Kanals 8 fluchtet. In der Stellung gemäss Fig. 5 treten die vorstehend erläuterten Probleme auf, welche jedoch durch Verschwenken der Düse 6 gemäss Fig. 6 behoben werden. In der Fig. 6 ist die zweiten Ausführungform der Vorrichtung so angeordnet, dass einerseits die halboffene Ausnehmung gebildet wird und andererseits die Düsenmündungen der Düse 6 zur Mündung des Kanals 8 entgegen der Schussrichtung versetzt sind. Wie bereits erwähnt sind, die Düsenlöcher 14 parallel zueinander angeordnet. Wird der Düse 6 Luft zugeführt, so wird mittels der Düsenlöcher 14 ein Luftvorhang erzeugt. Dieser Luftvorhang erstreckt sich quer zum Förderluftstrom für einen Schussfaden. Durch diesenFigures 5 to 7 show a second embodiment of the device. As shown in FIG. 7, in this device a nozzle holder 21 is divided into a base body 22 with the channel 8 and a plate-shaped holding element 23 for the nozzle 6. The holding element 23 is provided with the slotted bore in which the nozzle 6 is arranged and to be fastened to the base body by means of a screw 26. As shown in FIG. 7, the holding element 23 is arranged in such a way that on the one hand the semi-open recess 15 is formed and on the other hand the nozzle mouths of the nozzle 6 are aligned with the mouth of the channel 8. In the position according to FIG. 5, the problems explained above occur, which, however, are remedied by pivoting the nozzle 6 according to FIG. 6. 6, the second embodiment of the device is arranged in such a way that on the one hand the semi-open recess is formed and on the other hand the nozzle openings of the nozzle 6 are offset to the opening of the channel 8 against the direction of the shot. As already mentioned, the nozzle holes 14 are arranged parallel to one another. If air is supplied to the nozzle 6, an air curtain is generated by means of the nozzle holes 14. This air curtain extends across the conveying air flow for a weft thread. Through this
Luftvorhang wird in erster Linie der Förderluftstrom für den Schussfaden und somit auch der Schussfaden zur Kanalmündung abgedrängt und in den Kanal 8 geleitet. Dadurch wird in vorteilhafter Weise der Schussfaden sowohl durch den Luftstrom aus der Düse als auch durch die Förderluftstrom für den Schussfaden gestreckt gehalten und gespannt. Die Vorrichtung weist einen Düsenhalter (5) mit einem Kanal (8) zur Aufnahme eines Schussfadens und eine Düse (6) mit Düsenlöchern (14) zum Strecken und Spannen des Schussfadens auf. Die Düse (6) ist am Düsenhalter montiert, derart, dass die Düse bezüglich der Schussrichtung einstellbar, insbesondere schwenkbar oder versetzbar ist. Mit dieser Vorrichtung wird in vorteilhafter Weise die optimale Einstellung der Sich kreuzenden Luftstrahlen erleichtert und und unabhängig von der Fadenart eine Ablenkung des Schussfadens (9) gewährleistet und der Schussfaden sicher gespannt gehalten. Air curtain is primarily the conveyed air flow for the weft and thus also the weft to the mouth of the channel and pushed into the channel 8. As a result, the weft thread is advantageously stretched and tensioned both by the air flow from the nozzle and by the conveying air flow for the weft thread. The device has a nozzle holder (5) with a channel (8) for receiving a weft thread and a nozzle (6) with nozzle holes (14) for stretching and tensioning the weft thread. The nozzle (6) is mounted on the nozzle holder in such a way that the nozzle can be adjusted, in particular pivoted or displaced, with respect to the weft direction. With this device, the optimal setting of the intersecting air jets is advantageously facilitated and, regardless of the type of thread, deflection of the weft thread (9) is ensured and the weft thread is held securely under tension.
