Die Erfindung betrifft eine Vorrichtung zum Strecken und Spannen eines Schussfadens für eine Düsenwebmaschine gemäss dem Oberbegriff des Anspruches 1 und eine Webmaschine mit einer solchen Vorrichtung.The invention relates to a device for stretching and Tensioning a weft thread for a jet loom according to the preamble of claim 1 and one Loom with such a device.

In der DE-A-32 00 637 ist eine Düsenwebmaschine mit einem Schussfadenwächter und mit einer Spannvorrichtung zum Strecken und Gespannthalten eines Schussfadens bis zum Anschlag beschrieben. Diese Vorrichtung weist einen Körper mit einer halboffenen Ausnehmung auf, deren eine Begrenzungsfläche eine Lufteintrittsöffnung und deren andere Begrenzungsfläche eine Luftaustrittsöffnung aufweist. Die beiden Öffnungen liegen einander gegenüber und sind an einer Luftzufühleitung bzw. an einer Luftabsaugleitung angeschlossen, so dass in der Ausnehmung quer zur Schussrichtung ein Luftstrom erzeugt werden kann. Durch diesen Luftstrom wird der Endabschnitt eines einzutragenen Schussfadens nach dem Durchflug des Fadenwächters erfasst und in die Luftabsaugleitung ausgelenkt.DE-A-32 00 637 describes a jet loom with a Weft monitor and with a tensioning device for Stretching and holding a weft thread up to Described. This device has one Body with a half-open recess, one of which Boundary surface an air inlet opening and their other boundary surface an air outlet opening having. The two openings face each other and are on an air supply line or on a Air suction line connected so that in the Air flow generated recess perpendicular to the direction of fire can be. This air flow becomes the end section of a weft thread to be entered after the flight of the Thread monitor detected and in the air extraction line deflected.

Als nachteilig erweist sich bei diesen Vorrichtungen, dass lediglich ein gerichteter Luftstrahl zur Fadenablenkung vorgesehen ist. A disadvantage of these devices is that that only a directed air jet for Thread deflection is provided.

Der Erfindung liegt die Aufgabe eine Vorrichtung zum Strecken und Spannen eines Schussfadens zu verbessern.The invention has for its object a device To improve stretching and tensioning of a weft thread.

Diese Aufgabe wird Erfindungsgemäss durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1 solved.

Die Erfindung hat die Vorteile, dass die Düse einerseits zwei Luftstrahlen erzeugt, welche einen Luftvorhang bilden und dass die Düse andererseits bezüglich dem Kanal einstellbar ist. Dadurch wird unabhängig von der Fadenart eine Fadenablenkung gewährleistet und der Schussfaden sicher gespannt gehalten.The invention has the advantages that the nozzle on the one hand creates two air jets which create an air curtain form and that the nozzle on the other hand with respect to the channel is adjustable. This makes it independent of the type of thread a thread deflection ensures and the weft kept safely excited.

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.On the start page of a weaving machine are in Weft direction of a reed 1 with a guide channel 2 for one weft, one weft monitor 3 and one Device 4 of the type in question here downstream.

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 gerundeten 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. Reference is made to FIGS. 2 to 4. As the 4 shows, 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 is a channel for receiving a weft thread 9 and an approach 10, which has a slotted bore for receiving the nozzle 6 having. The nozzle 6 consists of a body 11 which a rectangular cross section with parallel Long sides and rounded narrow sides (Fig.2) and one has cylindrical approach 12. There are one in the nozzle Blind bore 13 and two nozzle holes 14 formed, the arranged parallel to each other and in the rounded 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.

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).2 shows the nozzle 6 in one position, in which is analogous to the prior art with the nozzle holes cursed the canal. Because of the intersecting Air jets encounter the known problems. Is the Conveying air flow for the weft thread stronger than air flow from the nozzle 6, the weft 9 is not correct distracted and excited. Is the airflow from the nozzle 6 the conveying air flow for the weft becomes stronger distracted before reaching the device. Consequently are the intersecting air currents on each other to coordinate, which is very complex. In the first Embodiment of the device is more advantageous Way this tuning the air flows by swiveling the Nozzle 6 and thus the generated air curtain easier (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. Figures 5 to 7 show a second embodiment the device. As Fig. 7 shows this Device a nozzle holder 21 in a base body 22nd with the channel 8 and a plate-shaped holding element 23 divided for the nozzle 6. The holding element 23 is with the slotted bore in which the nozzle 6 is arranged and by means of a screw 26 on Attach the base body. As Fig. 7 shows, that is Holding element 23 arranged so that the one hand semi-open recess 15 is formed and on the other hand the nozzle mouths of the nozzle 6 with the mouth of the channel 8 is aligned. 5 occur in the position problems explained above, but which are caused by Swiveling the nozzle 6 according to FIG. 6 can be eliminated. In 6 is the second embodiment of the device arranged so that on the one hand the semi-open recess is formed and on the other hand the nozzle orifices of the Nozzle 6 to the mouth of the channel 8 against Shot direction are offset.

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 diesen 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.As already mentioned, the nozzle holes 14 are parallel arranged to each other. If the nozzle 6 is supplied with air, so an air curtain is generated by means of the nozzle holes 14. This air curtain extends across the Conveying air flow for a weft. Through this Air curtain is primarily the conveying air flow for the weft and thus also the weft Channel mouth pushed and channeled into channel 8. This advantageously makes the weft thread both through the air flow from the nozzle and through the conveying air flow for the weft stretched held and excited. The device has one Nozzle holder (5) with a channel (8) for receiving a Weft and a nozzle (6) with nozzle holes (14) for Stretching and tensioning the weft. The nozzle (6) is mounted on the nozzle holder so that the nozzle adjustable with respect to the weft direction, in particular is pivotable or displaceable. With this device the optimal setting of the Crossing air jets relieved and and a distraction of the Weft thread (9) guaranteed and the weft thread safe kept excited.
