Description

Die Erfindung betrifft eine Luftwebmaschine mit den Merkmalen des Oberbegriffs von Patentanspruch 1.The invention relates to an air weaving machine with the features of the preamble of claim 1.

Eine ähnliche Luftwebmaschine beschreibt die US-A 3,621, 886. Auch hier greift ein Vorsprung des Breithaltertisches in den Schußeintragskanal, ist in diesem aber nicht mittig angeordnet. Beim Anschlagen des Schußfadens an das Gewebe hält dieses einen nur geringen Abstand von der oberen Begrenzung des Schußeintragskanals ein, so daß die Gefahr besteht, daß das Gewebe an die Begrenzung anstößt und dabei beschädigt wird.A similar air weaving machine is described in US Pat. No. 3,621,886. Here, too, a projection of the spreader table engages in the weft insertion channel, but is not arranged in the center thereof. When the weft thread hits the fabric, it maintains only a small distance from the upper boundary of the weft insertion channel, so that there is a risk that the fabric will abut the boundary and be damaged in the process.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Luftwebmaschine mit Webblatt und Breithaltertisch so weiterzubilden, daß unabhängig von der Art des Gewebes der Bindepunkt immer relativ in der Mitte des Schußeintragskanals gebildet wird.The invention is therefore based on the object of developing an air weaving machine with a reed and a spreader table so that the binding point is always formed relatively in the middle of the weft insertion channel, regardless of the type of fabric.

Die Lösung dieser Aufgabe erfolgt bei einer Luftwebmaschine mit den Merkmalen des Oberbegriffs von Patentanspruch 1 durch dessen Kennzeichen.This object is achieved in an air-jet weaving machine with the features of the preamble of claim 1 by its characteristics.

Der Bindepunkt des Gewebes im Schußeintragskanal wird also zentriert und es besteht somit nicht mehr die Gefahr, daß der Bindepunkt beispielsweise nach vorne oder unten in den Schußeintragskanal gerät.The binding point of the fabric in the weft insertion channel is thus centered and there is therefore no longer any danger that the binding point gets into the weft insertion channel, for example, forwards or downwards.

Erfindungsgemäß liegen also beim Anschlagen des Schußfadens an das Gewebe die Gewebeauflagefläche des Breithaltertisches und das Zentrum des Schußfadeneintragskanals in einer Ebene, womit der Idealfall für die Lage des Bindepunktes geschaffen wird.According to the invention, when the weft strikes the fabric, the fabric contact surface of the spreader table and the center of the weft insertion channel lie in one plane, thus creating the ideal case for the position of the binding point.

Weiterhin liegt damit das Gewebe außerhalb der Staffettendüsen und kann leicht über den Vorsprung des Breithaltertisches abgezogen werden.Furthermore, the fabric lies outside the relay nozzles and can easily be pulled off over the projection of the spreader table.

Der Vorsprung erlaubt also die Einstellung einer besonderen Fachgeometrie. Das Oberfach und das Unterfach können tiefer eingestellt werden (im Sack weben); dadurch besteht der Vorteil, daß die Staffettendüsen nicht am Gewebe abzeichnen und daß das Gewebe nicht an der unteren Nase des Webblattes aufläuft. Damit werden Gewebeschädigungen, die insbesondere auf Kettfadenbrüche zurückzuführen sind, vermieden.The lead therefore allows the setting of a special compartment geometry. The upper and lower compartments can be adjusted lower (weave in the sack); this has the advantage that the relay nozzles do not show on the tissue and that the tissue does not run onto the lower nose of the reed. This prevents tissue damage, which can be attributed in particular to warp thread breaks.

Im folgenden wird die Erfindung anhand einer lediglich einen Ausführungsweg darstellenden Zeichnung näher erläutert. Hierbei gehen aus der Zeichnung und aus ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile hervor.The invention is explained in more detail below with reference to a drawing which shows only one possible embodiment. Further features and advantages essential to the invention emerge from the drawing and from its description.

Die Figur zeigt einen erfindungsgemäßen Stabbreithalter.The figure shows a rod spreader according to the invention.

Ein nicht näher dargestelltes Webblatt besteht aus parallelen, einen gegenseitigen Abstand voneinander aufweisenden Webblattzähnen, von denen ein Webblattzahn in der Figur in einer Seitenansicht dargestellt ist. Der Webblattzahn 1 bildet einen Schußeintragskanal 2 mit einem Zentrum 2a aus, in den in nicht näher dargestellter Weise in senkrechter Richtung zur Zeichenebene der Schußfaden eingetragen wird und wobei die Kette in Pfeilrichtung 13 abgezogen wird.A reed, not shown, consists of parallel reed teeth, which are at a mutual distance from one another, of which one reed tooth is shown in the figure in a side view. The reed tooth 1 forms a weft insertion channel 2 with a center 2a, in which the weft thread is inserted in a manner not shown in the direction perpendicular to the plane of the drawing and the chain is pulled off in the direction of arrow 13.

Der Idealfall zur Bildung eines Bindepunktes 3 wird erreicht, wenn Kettfäden 5' und 6' im Zentrum 2a zusammenlaufen.The ideal case for forming a binding point 3 is achieved when warp threads 5 'and 6' converge in the center 2a.

Erfindungsgemäß ist nun der Stabbreithalter 15 mit einem Vorsprung 8 versehen, wobei der Vorsprung 8 in den Schußeintragskanal 2 hineingreift und die Vorderkante des Vorsprungs 8 etwa in der Mitte des Schußeintragskanals 2 liegt, d. h. die Mitte ist hierbei durch die vertikale Linie 11 und durch die horizontale Linie 7 der Auflagefläche des Vorsprungs 8 gegeben.According to the invention, the rod spreader 15 is now provided with a projection 8, the projection 8 engaging in the weft insertion channel 2 and the front edge of the projection 8 lying approximately in the middle of the weft insertion channel 2, i. H. the middle is given by the vertical line 11 and the horizontal line 7 of the contact surface of the projection 8.

Es ist erkennbar, daß durch die Auflage des Gewebes 9 auf dem Vorsprung 8 des Stabbreithalters 15 der Bindepunkt 3 stets etwa in der Mitte des Schußeintragskanals 2 zentriert wird.It can be seen that by placing the fabric 9 on the projection 8 of the rod spreader 15, the binding point 3 is always centered approximately in the middle of the weft insertion channel 2.

Der Stabbreithalter 15 mit dem Vorsprung 8 sorgt also dafür, daß der Bindepunkt 4 am Grund des Schußeintragskanals 2 (hinten) verbleibt und damit nicht die Gefahr besteht, daß das Gewebe mit der Kante des Webblattzahnes oder den Staffettendüsen kollidiert.The rod spreader 15 with the projection 8 thus ensures that the binding point 4 remains at the bottom of the weft insertion channel 2 (rear) and there is therefore no risk that the tissue collides with the edge of the reed tooth or the relay nozzles.

Der Stabbreithalter 15 besteht in an sich bekannter Weise aus einem Deckel 16 und aus einem Unterteil 17, wobei beide Teile über eine Befestigung 18 zusammengehalten sind.The rod spreader 15 consists in a manner known per se of a cover 16 and a lower part 17, both parts being held together by a fastening 18.

Das sich am Bindepunkt 3 bildende Gewebe 9 wird in den Gewebedurchlauf 19 hineingezogen, wobei der Stab 14 die Klemmung des Gewebes 9 nach jedem Anschlag durchführt.The tissue 9 forming at the binding point 3 is drawn into the tissue pass 19, the rod 14 clamping the tissue 9 after each stop.

Diese Ausführungsform des Stabbreithalters mit dem erfindungsgemäßen Vorsprung 8, der in den Schußeintragskanal 2 hineinragt, ist vor allem für dichte ggf. feine Gewebe geeignet, insbesondere für Einschütte, Percal und Segeltuche und dgl.This embodiment of the rod spreader with the projection 8 according to the invention, which protrudes into the weft insertion channel 2, is particularly suitable for dense, possibly fine, fabrics, in particular for drains, percal and canvas and the like.
