Damit wird erreicht, dass sowohl die Nadeln als auch das die Vielzahl von Führungsaugen aufweisende Mittel weder in Längsrichtung noch in Querrichtung Schwingungen ausführen, die den Webvorgang beeinträchtigen könnten.This ensures that both the needles and the plurality of guide eyes having means perform neither longitudinally nor transversely vibrations that could affect the weaving process.
Vorteilhaft wird vorgesehen, dass die Nadeln von oben nach unten gerichtet sind und zur Aufnahme der Kettfäden einer die Unterseite eines Webfachs bildenden Kettfadenschar dienen. Dadurch lassen sich die Antriebe, insbesondere für die Auf- und Abbewegung des bewegbaren Elementes unten anordnen, d.h. in einer Position, in der üblicherweise die Antriebe von Webschäften angeordnet sind. Damit ist es möglich, das Element mittels eines einem Antrieb für Webschäfte ähnelnden Antriebs anzutreiben.It is advantageously provided that the needles are directed from top to bottom and serve to receive the warp threads of a warp thread forming the underside of a shed. As a result, the drives, in particular for the up and down movement of the movable element can be arranged below, i. in a position in which usually the drives of Webschäften are arranged. This makes it possible to drive the element by means of a drive similar to a drive for heddle shafts drive.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, dass ein Antrieb mit eigenem Antriebsmotor zum Ausführen der Querbewegungen vorgesehen ist. Dadurch wird die Möglichkeit gegeben, ohne großen Aufwand an Einstellungen einer Maschine die Dreherbindungen zu ändern. Darüber hinaus ist es möglich, mittels eines derartigen Antriebsmotors die Bewegungen des mit der Vielzahl von Führungsaugen versehenen Elementes zu Zeiten durchzuführen, in welchen die darin geführten Kettfäden nicht an den stationär angeordneten Nadeln anliegen. Damit wird die Gefahr der Anregung der Nadeln zu Schwingungen reduziert. Außerdem wird die Gefahr eines Verschleisses der Nadeln vermindert.In a further embodiment of the invention, it is provided that a drive is provided with its own drive motor for carrying out the transverse movements. This gives the possibility to change the leno bindings without great effort on settings of a machine. Moreover, it is possible to perform by means of such a drive motor, the movements of the provided with the plurality of guide eyes element at times in which the guided therein warp threads do not abut the stationary arranged needles. This will reduce the risk of Stimulation of the needles reduced to vibrations. In addition, the risk of wear of the needles is reduced.

Die Webmaschine ist mit einem weiteren Querbalken 8 versehen, der sich ebenfalls über die gesamte Breite der Webmaschine erstreckt und der an den Seitenrahmen der Webmaschine befestigt ist. Zwischen der Trägerplatte 3 und dem zweiten Querbalken 8 sind in regelmäßigen Abständen voneinander Stützen 9 angebracht, um Verformungen der Trägerplatte 3, sowie der Querbalken 5 und 8 zu begrenzen.The loom is provided with a further
In regelmäßigen Abständen sind an der Trägerplatte 3 Halter 10 befestigt, beispielsweise mit nicht dargestellten Schrauben, die durch die Halter 2 hindurch in die Trägerplatte 3 eingeschraubt werden. Auf diesen Haltern 10 liegt eine Umlenkstange 11, die die Kettfäden umlenkt, die von den Führungsaugen der Nadeln geführt werden. Die Umlenkstange 11 wird mittels eines Klemmhalters 12 in einer definierten Axialposition an der Trägerplatte 3 befestigt.At
Zusätzlich zu den mit Führungsaugen für Kettfäden versehenen Nadeln 1 ist entsprechend
Das Element 13 wird mittels eines Antriebes, bei dem Ausführungsbeispiel mittels eines Exzenterantriebes, parallel zu der Reihe der Nadeln 1 hin- und herbewegt. Bei dem dargestellten Ausführungsbeispiel ist an die Querstrebe 17 des Rahmens 15 eine Verbindungsstange 24 angelenkt, die über einen Exzenter 25 von der Antriebswelle 27 eines regelbaren Antriebsmotors 28 angetrieben wird, um das Element 13 in Richtung des Pfeiles L hin- und herzubewegen. Der Antriebsmotor 28 ist bei dem Ausführungsbeispiel an dem Querbalken 8 befestigt. Er ist beispielsweise ein regelbarer, schaltbarer Reluktanzmotor. Der Exzenter 25 ist mittels Schrauben 26 auf einer Scheibe 33 befestigt, die drehfest auf der Antriebswelle 27 angeordnet ist. Der Exzenter 25 kann bei gelockerten Schrauben in Schlitzen 29 der Scheibe 33 verschoben und durch Festziehen der Schrauben 26 in einer vorgegeben radialen Stellung auf der Scheibe 33 befestigt werden. Dadurch ist es möglich, die Amplitude der Bewegung einzustellen, beispielsweise in Abhängigkeit von dem Abstand zwischen den Führungsaugen 14 des Elements 13. Wie aus

Beim Weben wird beispielsweise, ausgehend von der Position nach
Es ist selbstverständlich möglich, den Antriebsmotor 28 so zu steuern, dass das Element 13 nicht bei jedem Eintrag seitlich bewegt wird, sondern nur nach definierten Einträgen. In diesem Fall wird ein Drehergewebe erzeugt, bei dem die Kettfäden der Kettfadenscharen 37 und 38 nicht um jeden Schussfaden 43 eine Dreherbindung bilden, sondern nur nach einer Gruppe von mehreren Schussfäden. Selbstverständlich muss auch das Element 13 nicht für jeden Schusseintrag von der obersten in die unterste und wieder in die oberste Höhenposition gebracht werden. Es kann vorgesehen werden, dass diese Bewegung nur nach einer vorgegebenen Anzahl von Schusseinträgen erfolgt. Selbstverständlich sind auch Kombinationen der vorstehend beschriebenen Bewegungen möglich. Durch entsprechende Steuerung des Antriebsmotors 28 zu einer seitlichen Bewegung in beiden Richtungen mit dem Element 13 relativ zur Auf- und Abwärtsbewegung können Kettfäden der Kettfadenschar 37 in der untersten Position des Elementes 13 auf die gewünschte Seite der Nadeln 1 gebracht werden, um die entsprechende Dreherbindung zu erhalten.It is of course possible to control the
Bevorzugt wird die Herstellung eines Drehergewebes 42, bei welchem das Element 13 während jedes Eintrags seitlich in die eine oder die andere Richtung bewegt wird und bei welchem das Element 13 zwischen jedem Eintrag eine Auf- und Abwärtsbewegung ausführt, da in diesem Fall ein gut gebundenes Drehergewebe 42 erhalten wird. Ein derartiges Drehergewebe 42 ist insbesondere für die Verwendung als Teppichrücken geeignet. Damit wird auch der Vorteil erhalten, dass der Antriebsmotor 28 in eine Richtung mit nahezu konstanter Geschwindigkeit rotieren kann. Die Geschwindigkeit verläuft synchron zur Webmaschinengeschwindigkeit mit der halben Durchschnittsgeschwindigkeit. Die Geschwindigkeit des Antriebsmotors 28 muss nicht absolut synchron zur kontinuierlich veränderlichen Geschwindigkeit der Webmaschine sein. Sie muss nur im Mittel synchron zur Webmaschinengeschwindigkeit verlaufen. Dies bedeutet auch, dass der Antriebsmotor 28 so angetrieben werden muss, dass die von dem Element 13 geführten Kettfäden der Kettfadenschar 37 zu dem Zeitpunkt auf der gewünschten Seite der Nadeln positioniert werden, zu welchem die Kettfäden bei ihrer Aufwärtsbewegung gerade die Nadeln 1 passieren. Das Element kann sich zwischen den zwei oben genannten Zeitpunkten praktisch in einer beliebigen seitlichen Position befinden. Bevorzugt wird allerdings, dass sich das Element 13 zwischen den zwei vorstehend genannten Zeitpunkten in einer Position befindet, in welcher die Kettfäden möglichst nicht an den Nadeln 1 anliegen, um einen Verschleiß der Kettfäden und der Nadeln 1 aufgrund der Reibung der Kettfäden an den Nadeln 1 zu begrenzen. Im dargestellten Beispiel bedeutet das, dass der Exzenter 25 vom Antriebsmotor 28 beispielsweise pro Eintrag eines Schussfadens 43 um 180° verdreht wird, wobei der Antriebsmotor 28 mit veränderlicher Geschwindigkeit angetrieben wird. Diese veränderliche Geschwindigkeit kann so eingestellt werden, dass das Element 13 sich im wesentlichen in seitlicher Richtung zu einer Zeit bewegt, zu welcher sich dieses Element 13 im wesentlichen in der untersten Höhenposition unterhalb der Nadeln 1 befindet.Preference is given to the production of a

Ein derartiger Antrieb besteht beispielsweise aus einem von einer Welle der Webmaschine angetriebenen Nocken, der über Verbindungsstangen mit dem Element 13 oder 47 verbunden ist.

Obwohl die vorliegende Erfindung am Beispiel einer Luftdüsenwebmaschine dargestellt worden ist, ist ihre Anwendung nicht darauf beschränkt. Sie ist ohne weiteres auch in Verbindung mit anderen Webmaschinen, beispielsweise Greiferwebmaschinen, Greiferschützenwebmaschinen, Wasserstrahlwebmaschinen, Projektilwebmaschinen oder anderen Webmaschinen einsetzbar. Dabei besteht der Vorteil, dass die erfindungsgemäße Vorrichtung praktisch an jeder Webmaschine problemlos nachträglich angebaut werden kann.Although the present invention has been illustrated by the example of an air jet loom, its application is not limited thereto. It is also readily usable in conjunction with other weaving machines, such as rapier looms, Greiferschützenwebmaschinen, water jet looms, projectile or other weaving machines. There is the advantage that the device according to the invention can be easily retrofitted to virtually any weaving machine.
