Definitions
- the invention relates to a loom according to the preamble of Claim 1.
- the weft insertion means feature is broadest here Understood form and includes e.g. such as projectiles, Grippers, contactors, air jets, or other media for Inserting a weft thread into a warp thread Shed.
- Such weft insertion means are also in large number known.
- FR-A-2 547 602 is a defenseless weaving machine known in order to avoid the above disadvantages on everyone
- Leaf tooth guide elements for forming an entry channel are molded onto a weft by means of air jets bring in.
- this can increase the risk of getting caught of warp threads from untwisted yarns on the blow nozzles not be prevented because these are wider than that Distance between the leaf teeth and thus the warp threads and the latter are from the blow nozzles when pivoting the reed pushed apart.
- the thickness of the guide elements only the guide elements correspond to the thickness of the leaf tooth very thin and have insufficient stability and can bend and thus the danger of getting sympatheticed out of warp thread parts enlarge.
- the guide elements are definitely not suitable. Should one the leaf teeth would have to achieve sufficient stability and thus the guide elements are made thicker, so that only a coarser division of the reed teeth is possible would be, whereby only correspondingly coarser tissue is produced let.
- a weaving machine according to the preamble of claim 1 is known as the closest prior art, in which the reed is provided with a shooter guide, the Store tracks has sliding elements that extend in the direction of Stretch warp threads and engage between the warp threads.
- the sliding elements are wider than the warp thread spacing.
- a displacement element arranged, which is at least the same width as the sliding element however, has a greater height than this and forms an alley between the warp threads.
- the displacement elements form a tip.
- the displacement elements the warp threads have to be formed for every change of subject pushing apart an alley.
- This shooter guide can do not correct the problems described at the beginning because they is only suitable for high quality twisted yarns however for parallel yarns that are on the pointed displacement elements would be damaged or destroyed.
- the object of the invention is a weaving machine of the beginning mentioned type so that parallel threads can be processed and this even if they are not with are provided with a size.
- the deflection member preferably extends according to claim 2 preferably below the top of the guide element but to below the shed if the reed in the position furthest away from the stop edge of the fabric located.
- the deflection of the warp threads is improved when the weaving machine is designed according to claim 5.
- a reed tooth with the integrated guide element can be directly connected to the reed according to claim 9 be. In some cases, however, an embodiment can also be used be advantageous according to claim 10. But it is also conceivable if the guide element according to claim 11 formed in two parts is and a guide element part on the reed tooth and the other is arranged on a separate carrier.
- FIG. 1 shows the weaving area of a first weaving machine, the one device 2 for forming a shed 4 Warp threads 6 has. From the device 2 to form the In the shed, only strands 8 are shown which open the warp threads 6. and move and thus open, close and the shed change.
- the warp threads 6 are e.g. from parallel yarns, which are produced in the air swirling process and swirling points included as node 10.
- the warp threads 6 are brought together on the stop edge 12, on the means of a reed 14 an entered in the shed 4, but not shown weft thread is struck and thus serves to manufacture the fabric 16.
- the reed 14 consists of individual arranged in a reed T division Reed teeth 18 arranged in a lower carrier 20 and with each other at the upper end by a binding rod 22 are connected.

Abstract
Description
Die Erfindung betrifft eine Webmaschine gemäss Oberbegriff des
Anspruches 1.The invention relates to a loom according to the preamble of
Das Merkmal Schussfadeneintragsmittel wird hier in breitester Form verstanden und beinhaltet z.B. solche Mittel wie Projektile, Greifer, Schütze, Luftstrahl, oder andere Medien zum Eintragen eines Schussfadens in ein aus Kettfäden gebildetes Webfach. Solche Schussfadeneintragsmittel sind ebenfalls in grosser Zahl bekannt.The weft insertion means feature is broadest here Understood form and includes e.g. such as projectiles, Grippers, contactors, air jets, or other media for Inserting a weft thread into a warp thread Shed. Such weft insertion means are also in large number known.
Webmaschinen der eingangs genannten Art sind häufig Hochleistungswebmaschinen, bei denen die Schussfadeneintragsmittel in das Webfach ein- und austauchen. Hierzu sind Führungselemente erforderlich, bei denen sich Schwierigkeiten mit der Verarbeitung von Kettfäden aus Parallelgarnen ergeben. Parallelgarne bestehen aus einer Vielzahl (mindestens zwei) einzelner synthetischer Fibrillen oder Fasern, welche praktisch ohne Drehung parallel nebeneinander liegen. Damit die Fibrillen dieser Fäden nicht auseinander gehen, werden sie durch Schlichten zusammengeklebt oder durch ein Luftverwirbelungsverfahren abschnittweise untereinander verbunden. Garne, die durch Luftverwirbelung hergestellt worden sind, heissen luftverwirbeltes oder airentangledes Garn. Es besteht nun die Tendenz, dass die Kettfäden aus solchen Parallelgarnen an den Führungselementen aufgespaltet werden, so dass es zu Fibrillen- und/oder Fadenbrüchen kommt. Dadurch sinkt der Nutzeffekt solcher Hochleistungswebmaschinen drastisch, so dass letztlich solche Parallelgarne bei diesen Maschinen nicht verwendet werden können sondern nur teure gedrehte Garne, sogenannte Zwirngarne. Um eine gewisse Abhilfe zu schaffen, sind solche Parallelgarne zusätzlich mit einer Schlichte versehen. Abgesehen davon, dass solche Schlichtverfahren teuer sind, verschmutzt die Schlichte die Webmaschinen sehr stark. Ausserdem muss die Schlichte bei der Weiterverarbeitung der Gewebe ausgewaschen werden. Die ausgewaschene Schlichte muss durch ein sehr kostenintensives Verfahren umweltfreundlich entsorgt werden.Weaving machines of the type mentioned at the beginning are often high-performance weaving machines, where the weft insertion means dive in and out of the shed. There are guide elements for this required where there are difficulties with the Processing of warp threads from parallel yarns result. Parallel yarns consist of a large number (at least two) individual synthetic fibrils or fibers which are practical lie parallel next to each other without rotation. So that Fibrils of these threads don't go apart, they will glued together by finishing or by an air swirling process connected to each other in sections. Yarn, which are produced by air swirling are called air entangled or air entangled yarn. There is now the Tendency that the warp threads from such parallel yarns on the Guide elements are split up so that it leads to fibril and / or thread breaks. This reduces the efficiency such high performance looms drastically so that ultimately, such parallel yarns are not with these machines only expensive twisted yarns can be used, so-called thread yarns. To remedy this, are such parallel threads with an additional size Mistake. Apart from that, such arbitration are expensive, the size very dirty the looms strong. In addition, the size must be used for further processing the tissues are washed out. The washed out Sizing has to be done by a very cost-intensive process be disposed of in an environmentally friendly manner.
Aus der FR-A-2 547 602 ist eine schützenlose Webmaschine bekannt, bei der zur Vermeidung der obigen Nachteile an jedem Blattzahn Führungselemente zur Bildung eines Eintragskanals angeformt sind, um einen Schussfaden mittels Luftstrahlen einzubringen. Allerdings kann damit die Gefahr des Hängenbleibens von Kettfäden aus ungedrehten Garnen an den Blasdüsen nicht verhindert werden, denn diese sind breiter als der Abstand der Blattzähne und damit der Kettfäden und letztere werden von den Blasdüsen beim Verschwenken des Webblattes auseinandergedrängt. Da die Dicke der Führungselemente nur der Dicke des Blattzahnes entspricht sind die Führungselemente sehr dünn und haben keine ausreichende Stabilität und können sich verbiegen und dadurch die Gefahr des Bängenbleibens von Kettfadenteilen vergrössern. Zur Führung von Schusseintragsorganen sind sie schon gar nicht geeignet. Soll eine ausreichende Stabilität erreicht werden, müssten die Blattzähne und damit die Führungselemente dicker ausgebildet sein, so dass nur eine gröbere Teilung der Webblattzähne möglich wäre, wodurch sich nur entsprechend gröbere Gewebe herstellen liessen.FR-A-2 547 602 is a defenseless weaving machine known in order to avoid the above disadvantages on everyone Leaf tooth guide elements for forming an entry channel are molded onto a weft by means of air jets bring in. However, this can increase the risk of getting caught of warp threads from untwisted yarns on the blow nozzles not be prevented because these are wider than that Distance between the leaf teeth and thus the warp threads and the latter are from the blow nozzles when pivoting the reed pushed apart. Because the thickness of the guide elements only the guide elements correspond to the thickness of the leaf tooth very thin and have insufficient stability and can bend and thus the danger of getting freaked out of warp thread parts enlarge. For guiding weft insertion organs they are definitely not suitable. Should one the leaf teeth would have to achieve sufficient stability and thus the guide elements are made thicker, so that only a coarser division of the reed teeth is possible would be, whereby only correspondingly coarser tissue is produced let.
Aus der DE-U-91 00 753 ist als nächstliegender Stand der Technik eine Webmaschine gemäss Oberbegriff des Anspruches 1 bekannt, bei der
das Webblatt mit einer Schützenführung versehen ist, deren
Ladenbahnen Gleitelemente aufweist, die sich in Richtung der
Kettfäden erstrecken und zwischen die Kettfäden eingreifen.
Die Gleitelemente sind breiter als der Kettfadenabstand. Vor
oder hinter jedem Gleitelement ist ein Verdrängerelement
angeordnet, das mindestens die gleiche Breite wie das Gleitelement
jedoch eine grössere Höhe als dieses aufweist und
zwischen dem Kettfaden eine Gasse bildet. Am freien Ende
bilden die Verdrängerelemente eine Spitze. Die Verdrängerelemente
müssen bei jedem Fachwechsel die Kettfäden zur Bildung
einer Gasse auseinanderdrängen. Diese Schützenführung kann
die eingangs geschilderten Probleme nichtbeheben, denn sie
ist nur für hochwertige gezwirnte Garne geeignet nicht
jedoch für Parallelgarne, die an den spitzen Verdrängerelementen
beschädigt oder zerstört würden. From DE-U-91 00 753 a weaving machine according to the preamble of
Aufgabe der Erfindung ist es, eine Webmaschine der eingangs genannten Art so auszugestalten, dass auch Parallelgarne verarbeitet werden können und dies, selbst wenn sie nicht mit einer Schlichte versehen sind.The object of the invention is a weaving machine of the beginning mentioned type so that parallel threads can be processed and this even if they are not with are provided with a size.
Die gestellte Aufgabe wird gelöst durch die kennzeichnenden
Merkmale des Anspruches 1.The task is solved by the characteristic
Features of
Dadurch, dass das Ablenkorgan am Webblattzahn einstückig angeformt ist, wird es möglich, auch bei modernen Hochleistungswebmaschinen Parallelgarne zu verarbeiten, auch wenn sie nicht mit einer Schlichte versehen sind. Das bedeutet, dass kostengünstig herstellbare Parallelgarne verarbeitet werden können und dies auf schnell laufenden Hochleistungswebmaschinen. Überdies ist ein nachträgliches Auswaschen der nun nicht mehr vorhandenen Schlichte nicht mehr notwendig. Die sich daraus ergebenden Kostenvorteile sind offensichtlich.The fact that the deflector on the reed tooth in one piece is molded, it becomes possible even with modern high-performance weaving machines Process parallel threads, even if they are not provided with a size. That means, that processed parallel yarns at low cost on high-speed, high-performance weaving machines. In addition, a subsequent washing out of the no longer required sizing. The resulting cost advantages are obvious.

In den nachfolgenden Ausführungsbeispielen und Figuren sind identische Bauteile mit gleichen Bezugszeichen versehen.In the following examples and figures Identical components with the same reference numerals.
Die Figur 1 zeigt den Webbereich einer ersten Webmaschine,
die eine Vorrichtung 2 zur Bildung eines Webfaches 4 aus
Kettfäden 6 aufweist. Von der Vorrichtung 2 zur Bildung des
Webfaches sind nur Litzen 8 gezeigt, die die Kettfäden 6 auf-
und abbewegen und somit das Webfach öffnen, schliessen und
verändern. Die Kettfäden 6 bestehen z.B. aus Parallelgarnen,
die im Luftverwirbelungsverfahren hergestellt sind und Verwirbelungspunkte
als Knoten 10 enthalten. Die Kettfäden 6
sind an der Anschlagkante 12 zusammengeführt, an der mittels
eines Webblattes 14 ein in das Webfach 4 eingetragener,
jedoch nicht dargestellter Schussfaden angeschlagen wird und
so zur Herstellung des Gewebes 16 dient. Das Webblatt 14
besteht aus einzelnen in einer Webblatteilung T angeordneten
Webblattzähnen 18, die in einem unteren Träger 20 angeordnet
und am oberen Ende durch einen Bindestab 22 miteinander
verbunden sind. Das Webblatt ist am Blatthebel 23 fest eingespannt.
Am Blatthebel 23 sind überdies Führungselemente 24
angeordnet, die zur Führung von Schussfadeneintragsmitteln 26
dienen, welche im vorliegenden Fall ein Eintragsband 28
aufweisen, das zwischen zwei nutenartigen Ausnehmungen 30 in
Zähnen 32,34 des Führungselementes 24 geführt sind. Das
Führungselement 24 ist koplanar zu der in Bewegungsrichtung
liegenden Mittelebene M eines zugehörigen Webblattzahnes 18a
angeordnet, wie sich insbesondere aus Figur 3 ergibt. Zwischen
dem Webblattzahn 18a und dem Führungselement 24 ist ein
Ablenkorgan 36 vorhanden, das einstückig mit dem Webblattzahn
18a ausgebildet ist. Das Ablenkorgan für die Kettfäden 6
erweitert sich beidseits der Mittelebene M in Richtung 38 des
Schussfadenverlaufes, so dass es vom Webblattzahn 18a ausgehend
eine keilförmige Führung für die Kettfäden bildet und
diese seitlich an den Führungselementen 24 vorbei bewegt,
ohne dass die Gefahr besteht, dass die Kettfäden an den
Führungselementen 24 hängen bleiben.FIG. 1 shows the weaving area of a first weaving machine,

wie in Figur 1 gezeigt ist. Nach oben und nach unten
ist das Ablenkorgan 36 mit sich verjüngenden Abschnitten
42,44 versehen, um das Ablenken der Kettfäden beim Ein- und
Ausfahren in das Webfach zu erleichtern. In der in Figur 1
strichpunktiert dargestellten Anschlagstellung des Webblattes
liegt das Ablenkorgan unterhalb der Anschlagkante.The
Das Ablenkorgan ist vorzugsweise so ausgebildet, dass die
grösste Breite B des Ablenkorganes höchstens dem Zehnfachen
der Teilung T des Webblattzahnes entspricht. Die Länge L des
Ablenkorganes in Bewegungsrichtung des Webblattes 14 beträgt
mindestens die halbe Dicke d des Webblattzahnes 18a. Im
gezeigten Beispiel entspricht der Abstand A benachbarter
Ablenkorgane 36 der doppelten Teilung T der Webblattzähne 18.The deflector is preferably designed so that the
maximum width B of the deflector at most ten times
corresponds to the pitch T of the reed tooth. The length L of the
