Abstract

The machine (1) has a frame which actuated by the water tubes (4) corresponding to the associated nozzle (40). A guide slot (6) is provided in the flow connection (2,9) along the speed-shifting direction of the valves (3,8). The impact bars (19,21) are spaced from the water tube associated with non-positive or positive fit. The monolithic tubular element (30) is provided with the thread passages (22) that are provided with corresponding to the tube rows (23-25).

Description

Die Erfindung betrifft eine Anordnung für eine Webfachbildung von Webmaschinen nach der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to an arrangement for a shedding of weaving machines according to the type specified in the preamble of claim 1.

Im Stand der Technik sind viele Ausführungsformen von Webfachbildungen bekannt und im Einsatz.In the prior art many embodiments of sheds are known and in use.

Dabei sind Webschäfte mit Oberfach und Unterfach Bildung allein durch schnelles pneumatisches Heben und Senken der Kettfäden bisher nicht beschrieben.In this case, healds with upper compartment and lower compartment formation are not yet described solely by rapid pneumatic lifting and lowering of the warp threads.

Erfindungsgemäß wird deshalb vorgeschlagen Kettfäden durch in einer Ebene angeordnete teilweise axial geschlitzte Röhrchen laufen zu lassen, wobei die Schlitzlänge der jeweiligen maximalen Fachhubhöhe entspricht und die Ober- und Unterfachbildung durch abwechselnde Drucklufteinblasung in das obere und untere Ende der Röhrchen realisiert wird.Therefore, it is proposed according to the invention to run warp threads arranged in a plane partially axially slotted tube, wherein the slot length of the respective maximum Fachhubhöhe corresponds and the upper and Unterfachbildung is realized by alternating compressed air injection into the upper and lower end of the tube.

Damit sind Jacquard Muster ohne aufwendige webfachbildende träge Mechanik realisierbar.This jacquard pattern can be realized without complex webfachbildende sluggish mechanics.

In folgendem wird die Erfindung anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit fünf Zeichnungen beschrieben. Dabei zeigt:In the following the invention will be described with reference to a preferred embodiment in conjunction with five drawings. Showing:

1 eine vereinfachte Seitenansicht des Röhrchens (4) mit dem Führungsschlitz (6) durch den der Kettfaden (5) durch die über die Richtungsventile (3, 8) alternierend nach der Vorgabe des Webprogramms der Webmaschine (1) Druckluft einbläst, die den Kettfaden (5) gegen die Prallleiste (21) oder gegen die Prallleiste (19) drückt. Die Prallleisten sind vorgesehen, damit durch die große Auftreffgeschwindigkeit des Kettfadens (5) dieser nicht auf Kanten der Endanschläge (7, 10) auftrifft. Wegen der hohen Energie würde der Kettfaden (5) beschädigt und der Webstoff damit unbrauchbar. Als Richtungsventil können schnellschaltende elektromagnetische oder auch piezoelektrische Ventile eingesetzt werden. Diese Technik kann sehr gut mit Webmaschinen kombiniert werden, bei denen der Schussfaden mittels Druckluft in das Webfach eingebracht wird, da es hierdurch zu einer lange gewünschten Leistungsanpassung der Webfachbildung an die sehr schnellen Druckluft betriebenen Webmaschinen kommt. Als Ventile können alternativ auch Wechselventile eingesetzt werden die auf der einen Seite des Röhrchens (4) einen positiven Druck erzeugen und auf dessen gegenüberliegenden Seite einen negativen Druck erzeugen. Hierdurch wird ein besserer Kettfaden Transport sichergestellt. 1 a simplified side view of the tube ( 4 ) with the guide slot ( 6 ) through the warp thread ( 5 ) by the over the directional valves ( three . 8th ) alternately according to the specification of the weaving machine weaving program ( 1 ) Blowing in the compressed air that 5 ) against the impact bar ( 21 ) or against the impact bar ( 19 ) presses. The impact strips are provided so that the large impact speed of the warp thread ( 5 ) this not on edges of the end stops ( 7 . 10 ). Because of the high energy the warp thread ( 5 ) and the woven fabric thus unusable. As a directional valve fast switching electromagnetic or piezoelectric valves can be used. This technique can be very well combined with weaving machines, in which the weft thread is introduced by means of compressed air in the shed, since this leads to a long desired performance adjustment of the shed forming on the very fast compressed air operated looms. Alternatively, shuttle valves can be used as valves on one side of the tube ( 4 ) generate a positive pressure and generate a negative pressure on its opposite side. This ensures a better warp transport.

2 eine vereinfachter Längsschnitt des Röhrchens (4) mit der Kettfadenzuführungsleiste (16), der Garnrolle (17) und der Nulllage der Kettenfadenebene (11). 2 a simplified longitudinal section of the tube ( 4 ) with the warp thread supply strip ( 16 ), the spool ( 17 ) and the zero position of the warp thread level ( 11 ).

3 eine vereinfachte Schnittansicht einer Draufsicht der monolithischen Ausführung eines einreihigen Röhrchenelementes (30) mit den Fadendurchgänge (22 ... n) und den Prallleisten (15, 21). three 5 is a simplified sectional view of a top view of the monolithic embodiment of a single-row tube element (FIG. 30 ) with the thread passages ( 22 ... n) and the impact bars ( 15 . 21 ).

4 eine Ansicht bei dem zur größeren Einbringung von Kettfäden in das Webfach das Röhrchenelement (31) zweireihig mit Röhrchen versehen ist. 4 a view in which the larger contribution of warp threads in the shed the tube element ( 31 ) is double rowed with tubes.

5 eine Ansicht des Röhrchens (4) mit einem Düsenkörper (40). 5 a view of the tube ( 4 ) with a nozzle body ( 40 ).
