Description
Die Erfindung betrifft eine Webmaschine zur Herstellung von Drehergeweben gemäss Oberbegriff von Anspruch 1 und ein Verfahren zum Reinigen einer Webmaschine gemäss Oberbegriff von Anspruch 7.The invention relates to a loom for producing leno fabrics according to the preamble of
Neuere Generationen von Webmaschinen für die Herstellung von Drehergeweben, insbesondere von Drehergeweben, welche als Grundgewebe für die Teppichherstellung dienen, werden mit zunehmend höheren Drehzahlen betrieben. Die Erhöhung der Drehzahlen wurde vor allem durch die Verwendung von Luftdüsen-Schusseintragssystemen möglich, womit eine beachtliche Leistungssteigerung erzielt werden konnte. Mit dieser Leistungssteigerung nahm auch die Verunreinigung durch Faserflug zu. Je nach Art des Kettfadenmaterials bilden sich im Bereich der Drehervorrichtung, genauer gesagt an den Elementen der Drehervorrichtung, z.B. an Nadelbarren, Umlenkelementen oder Legeschienen, Ansammlungen von Faserflug. Besonders extrem ist die Faserflugbildung bei Verwendung von Fasergarnen, wie z.B. Baumwolle.More recent generations of weaving machines for the production of leno fabrics, particularly leno fabrics, which serve as the base fabric for carpet manufacture, are operating at increasingly higher speeds. The increase in rotational speeds was made possible above all by the use of air jet weft insertion systems, with which a considerable increase in performance could be achieved. With this increase in performance, the contamination by fiber fly also increased. Depending on the type of warp thread material, in the area of the leno device, more precisely on the elements of the leno device, e.g. on needle bars, deflection elements or guide rails, accumulations of fiber fly. Fibrous formation is particularly extreme when using fiber yarns, e.g. Cotton.
In einer Webmaschine zur Herstellung von Geweben mit einfachen Kettfadensystemen, wie beispielsweise Gewebe mit Leinwandbindung und deren Ableitungen, kreuzen sich die Kettfäden bei jeder neuen Fachbildung, d.h. die unteren Kettfäden kommen nach oben zu liegen und die oberen nach unten. Durch dieses Kreuzen der Kettfäden bei der Fachbildung werden grössere Ansammlungen von Faserflug im Webfach weitgehend vermieden.In a weaving machine for the production of fabrics with simple warp yarn systems, such as plain weave fabrics and their derivatives, the warp yarns intersect at each new shed formation, ie the lower warp yarns come up and the upper ones down. By this crossing of the warp threads in the shedding larger accumulations of fiber fly in the shed are largely avoided.
Bei der Herstellung von Drehergeweben, insbesondere von Halbdrehergeweben, welche als Grundgewebe für die Teppichherstellung dienen, liegen im Webfach immer die selben Kettfäden oben beziehungsweise unten. Die Steher- und die Dreherfäden werden nach einem Schusseintrag nur soweit gegeneinander angehoben, als es für den Seitenwechsel der Dreherfäden notwendig ist. Der Faserflug kann sich so an den Elementen der Drehervorrichtung ungehindert ansammeln. Dies trifft insbesondere für den hinteren Bereich des Webfaches zu. Grössere Ansammlungen, welche sich von den Elementen der Drehervorrichtung lösen, sind zusätzlich im Bereich des Webfaches zwischen den Steher- und Dreherfäden eingeschlossen und lassen sich von dort nur mit Mühe entfernen.In the production of leno fabrics, in particular of Halbdrehergeweben, which serve as a base fabric for the carpet production, lie in the shed always the same warp threads above or below. The uprights and the leno threads are raised as far as one another after a weft insertion, as it is necessary for the side change of the leno threads. The fiber fly can thus accumulate unhindered on the elements of the leno device. This is especially true for the back of the shed. Larger accumulations, which detach themselves from the elements of the leno device, are additionally enclosed in the area of the shed between the staple and leno threads and can be removed from there only with difficulty.
Zur Vermeidung von Verstopfungen in den Fadenpassagen der Drehervorrichtung, sowie von hieraus resultierenden Fadenbrüchen und entsprechenden längeren Stillstandszeiten der Webmaschinen, müssen die neueren Webmaschinen für die Herstellung von Drehergeweben vorsorglich zwecks Entfernung von Faserflugansammlungen angehalten werden. Dies ist zeitaufwendig und vermindert die Webleistung. Sogenannte Wanderreiniger (Overheadcleaners), wie sie aus dem Stand der Technik bekannt sind, ergeben in den kritischen Bereichen der Drehervorrichtung einen nur ungenügenden Reinigungseffekt.To avoid clogging in the yarn passages of the leno device, as well as resulting yarn breaks and corresponding longer downtime of the looms, the newer looms for the production of leno fabrics must be stopped as a precaution to remove fiber fly accumulations. This is time consuming and reduces web performance. So-called "overhead cleaners", as known from the prior art, produce an insufficient cleaning effect in the critical areas of the leno device.

Vorzugsweise werden die Düsen periodisch und/oder zyklisch und/oder nacheinander und/oder bedarfsweise mit Druckluft beaufschlagt werden. Vorzugsweise wirken die genannten Düsen mit wenigstens einer im Wesentlichen senkrecht ausgerichteten Düse und/oder mit wenigstens einer im Wesentlichen horizontal entgegen der Laufrichtung der Steher- und den Dreherfäden ausgerichteten Düse zusammen.In a further preferred embodiment of the method, the shed is formed in a known manner from core threads and leno threads. In addition, the integrated cleaning device comprises a plurality of nozzles, by means of which in the region between the uprights and the leno threads, in particular in the rear part of the shed, a substantially horizontal compressed air flow is generated transversely to the running direction of the stayer and leno threads. Preferably, the nozzles will be applied periodically and / or cyclically and / or sequentially and / or as required with compressed air. Preferably, said nozzles cooperate with at least one substantially vertically aligned nozzle and / or with at least one substantially horizontally aligned opposite to the direction of travel of the stayer and the leno threads nozzle together.
Mittels der in die erfindungsgemässe Webmaschine integrierten Reinigungsvorrichtung und insbesondere mittels der beschriebenen Düsenanordnungen können Verunreinigungen im Bereich der Drehervorrichtung und des Webfaches wirkungsvoll entfernt werden. Eine vorteilhafte Reinigungswirkung ergibt sich, wenn Düsen mit unterschiedlicher Anordnung und/oder mit unterschiedlicher Orientierung der Druckluft- und/oder Saugluftströme kombiniert werden, beispielsweise eine oder mehrere Düsen mit im Wesentlichen vertikal gerichteten Druckluft- und/oder Saugluftströmen mit einer oder mehreren Düsen mit im Wesentlichen horizontal gerichteten Druckluft- und/oder Saugluftströmen. Besonders vorteilhaft ist eine Düsenanordnung, mittels welcher zwischen den Steher- und den Dreherfäden ein im Wesentlichen horizontaler Druckluftstrom quer zur Laufrichtung der Steher- und Dreherfäden erzeugbar ist und mittels welchen Verunreinigungen, insbesondere auch Faserflugansammlungen, die im Bereich des Webfaches zwischen den Steher- und Dreherfäden eingeschlossen sind, entfernt werden können.By means of the cleaning device integrated in the weaving machine according to the invention and in particular by means of the nozzle arrangements described, it is possible to effectively remove impurities in the area of the leno device and the shed. An advantageous cleaning effect results when nozzles are combined with different arrangement and / or with different orientation of the compressed air and / or Saugluftströme, for example, one or more nozzles with substantially vertically directed compressed air and / or Saugluftströmen with one or more nozzles with Essentially horizontally directed compressed air and / or suction air streams. Particularly advantageous is a nozzle arrangement, by means of which between the upright and the leno threads a substantially horizontal compressed air flow transversely to the running direction of the stayer and leno threads is generated and by means of which impurities, in particular fiber fly accumulations, in the region of the shed between the stayer and leno threads are included can be removed.
