Description

Die Erfindung betrifft eine Vorrichtung zum Bilden einer Dreherkante nach dem Oberbegriff des Patentanspruchs 1 sowie eine Webmaschine mit derartigen Vorrichtungen.The invention relates to a device for forming a leno selvedge after Preamble of claim 1 and a loom with such Devices.

Vorrichtungen zum Bilden einer Dreherkante sind aus der DE 25 38 135 C2 und aus der DE 28 11 275 A1 bekannt.
Die Vorrichtungen besitzen zwei Dreherfadenspulen, von denen die Dreherfäden zur Kantenbildung am Gewebe abgezogen werden.
Außer daß die Vorrichtungen synchron mit der Webmaschine drehbar angetrieben sind, bzw. vorzugsweise mit dem Webmaschinenantrieb kombiniert sind, sind konkrete Merkmale über deren Antrieb und Steuerung nicht offenbart.
Zur Aufrechterhaltung der Fadenspannung bei Fachwechsel sind die Vorrichtungen mit Spannmittel ausgerüstet, z.B. mit Spannfedern.
Devices for forming a leno selvedge are known from DE 25 38 135 C2 and from DE 28 11 275 A1.
The devices have two leno reel spools, from which the leno threads are pulled off to form the edge on the fabric.
Except that the devices are rotatably driven synchronously with the weaving machine, or preferably combined with the loom drive, concrete features about their drive and control are not disclosed.
In order to maintain the thread tension at a change of subject, the devices are equipped with clamping means, eg with tension springs.

Aus der EP 0 020 796 A1 ist eine Dreherfaden-Liefervorrichtung für Webmaschinen bekannt, von der aus die Dreherfäden unter der Wirkung eines Fadenspanners einer Kantenbildeeinrichtung zugeführt werden. Die Art des Antriebes der Kantenbildeeinrichtung ist, wenn die Einrichtung eine Dreherscheibe oder ein zur Dreherscheibe äquivalentes Mittel ist, nicht offenbart.EP 0 020 796 A1 discloses a leno thread delivery device for weaving machines known from which the leno threads under the action of a thread tensioner an edge forming device are supplied. The type of drive the Edge forming device is when the device is a leno or a for Turner disc equivalent means is not disclosed.

Schließlich ist aus der US-PS 2,399, 880 eine Vorrichtung zum Bilden einer Dreherkante an auf Webmaschinen herzustellendem Gewebe bekannt. Die Vorrichtung besteht aus einer drehangetriebenen Dreherscheibe, deren Antrieb vom Webmaschinenantrieb abgeleitet ist.
Wie die Dreherfäden bei Wechsel des Dreherfaches gespannt gehalten werden, wird nicht offenbart. Die Dreherfadenspulen sind lediglich mit einem Bremsmittel ausgerüstet, das die Spannung des Dreherfadens auf dem Wege von der Dreherspule zur Dreherscheibe aufrechterhalten soll.
Finally, US Pat. No. 2,399,880 discloses an apparatus for forming a leno selvage on tissue to be produced on weaving machines. The device consists of a rotationally driven leno disk whose drive is derived from the weaving machine drive.
How the leno threads are kept curious when changing the leno compartment is not disclosed. The leno reel spools are equipped only with a braking means to maintain the tension of the leno thread on the way from the leno spool to the leno wheel.

Allen vorstehend genannten Vorrichtungen zum Bilden einer Gewebekante ist gemeinsam, daß die Gewebekante nicht durch Dreherfäden führende Mittel gebildet wird, die in ihrer Drehrichtung umkehrbar angetrieben sind.All the aforementioned devices for forming a fabric edge is in common that the fabric edge is not formed by leno threads leading means is reversibly driven in their direction of rotation.

Eine Dreherkantenvorrichtung der im Oberbegriff des Patentanspruchs 1 genannten Art ist aus der DE 195 48 955 C1 bekannt.
In einer ersten Anordnungsversion der Dreherkantenvorrichtung ist die Drehachse des Rotors parallel zu den Kettfäden und außerhalb der Webschäfte angeordnet. Aufgrund des von dem Führungselement beanspruchten Freiraumes zur Rotation neben dem äußeren Kettfaden wird eine Dreherkante erzeugt, die in einem Abstand vom eigentlichen Geweberand entfernt liegt.
Eine solche Dreherkante macht anwendungstechnisch keinen Sinn.
A leno device referred to in the preamble of claim 1 is known from DE 195 48 955 C1.
In a first arrangement version of the leno selvedge device, the axis of rotation of the rotor is arranged parallel to the warp threads and outside the heddle shafts. Due to the space occupied by the guide element for rotation in addition to the outer warp a leno edge is generated, which is located at a distance from the actual fabric edge.
Such a leno selvedge makes no sense in terms of application technology.

Um die Dreherkante anwendungstechnisch sinnvoll unmittelbar neben dem äußeren Kettfaden eines Gewebes zu erzeugen, ist in einer zweiten Anordnungsversion der Drehervorrichtung die Drehachse des Rotors in einem Winkel von vorzugsweise 45° zu den Kettfäden angeordnet und im Zusammenhang damit eine Umlenkrolle für die Dreherfäden erforderlich.Around the leno selvedge, in terms of application, makes sense directly next to the outer one Warp thread of a fabric is in a second arrangement version of the Turning device, the axis of rotation of the rotor at an angle of preferably 45 ° arranged to the warp threads and in connection therewith a deflection roller for the Leno threads required.

Die Patentschrift offenbart nicht, ob es sich hierbei um eine drehend gelagerte oder um eine drehfest angeordnete oder um eine drehangetriebene Umlenkrolle handelt. Insofern wird auch nicht offenbart, wie ein durch die Rotation des Führungselementes der Dreherkantenvorrichtung sich aufbauender Stau verkordelter Dreherfäden an der Umlenkrolle vermieden wird, wie ferner in diesem Zusammenhang vermieden wird, daß die Dreherfaden-Fachbildung gestört und wie des weiteren Dreherfadenbrüche, die auf der Fadenverkordelung beruhen, vermieden werden.The patent does not disclose whether this is a rotationally mounted or is a rotatably mounted or a rotationally driven pulley. In this respect, it is also not revealed how a by the rotation of the Guide element of the leno selector device accumulating congestion trimmed leno threads is avoided on the pulley, as further in this Context is avoided that disrupted the leno thread shedding and how further leno thread breaks based on threading be avoided.

Bei der Anmelderin durchgeführte Erprobungen von Dreherkantenvorrichtungen mit rotierendem Fadenführungselement und mit einer umlenkenden Führung der Dreherfäden haben gezeigt, daß bei einer drehfest angeordneten Umlenkrolle und bei der Verwendung eines dehnungsarmen, reißfesten Dreherfadenmaterials der Qualität Nm200/1 sich ein Dreherfaden-Fach wegen der Verkordelung an der Umlenkwelle nicht synchron zum Webfach und zum Schußfadeneintrag aufbaut und folglich der Schußfaden entweder fehlerhaft oder gar nicht am Geweberand abgebunden wird.
Ist die Umlenkrolle als solche z.B. drehend gelagert, kann ein ungewolltes Rückwärtsdrehen der Rolle, hervorgerufen durch Maschinenschwingungen, nicht ausgeschlossen werden.
Auch in einem solchen Fall ist die Dreherfaden-Fachöffnung blockiert und daher der Schußfadeneintrag als auch das Bilden der Dreherkante gestört.
Experiments conducted by the applicant of Dreherkantenvorrichtungen with rotating thread guide element and with a deflecting leadership of the leno threads have shown that in a rotatably mounted pulley and using a low-stretch, tear-resistant leno thread of quality Nm200 / 1, a leno thread tray because of the cabling on the Deflection shaft is not synchronous to the shed and the weft insertion builds up and consequently the weft thread is tied either incorrectly or not at the fabric edge.
If the deflection roller as such, for example, mounted rotatably, unintentional reverse rotation of the role, caused by machine vibrations, can not be excluded.
Even in such a case, the leno thread tray opening is blocked and therefore the weft insertion as well as the formation of the leno selvedge are disturbed.

In einer weiteren in der oben genannten DE 195 48 955 C1 offenbarten Dreherkantenvorrichtung ist die Drehachse des Rotationskörpers, welche als Hohlwelle ausgebildet ist, rechtwinklig zu den Kettfäden ausgerichtet. Hierbei sind auf der Hohlwelle wenigstens zwei Führungselemente beabstandet voneinander angeordnet.
Nachteil ist hier, daß aufgrund der häufigen Dreherfaden-Umlenkungen auf dem Weg von den Spulen bis zum Gewebe ein Zugspannungsausgleich in den Dreherfäden bei jedem Fachwechsel nicht erfolgt und daher keine korrekte Fachausbildung gegeben ist.
Dieser Nachteil führt dazu, daß der Schußfadeneintrag z.B. auf einer Luftdüsenwebmaschine nicht korrekt erfolgen kann, weil der Schußfaden mit dem betreffenden zugspannungslosen Dreherfaden kollidiert.
In another disclosed in the above-mentioned DE 195 48 955 C1 leno device is the axis of rotation of the rotating body, which is designed as a hollow shaft, aligned at right angles to the warp threads. Here, at least two guide elements are spaced from each other on the hollow shaft.
Disadvantage here is that due to the frequent leno thread deflections on the way from the coils to the fabric a tension compensation in the leno threads at each subject change does not occur and therefore no correct technical training is given.
This disadvantage means that the weft insertion can not be done correctly, for example on an air jet loom, because the weft thread collides with the respective tensionless leno thread.

Eine funktionsfähige Lösung kann hier darin bestehen, daß, wenn sich z.B. die Dreherfäden im Fachwechsel befinden, eine Spannkraft auf die Dreherfäden aufgebracht wird.
Die vorgenannten nachteiligen Wirkungen, die der zuletzt erwähnten Vorrichtung anhaften, treten gleichermaßen bei der genannten Dreherkantenvorrichtung auf, deren Drehachse in einem Winkel von etwa 45° zu den Kettfäden gelegen ist.
A functional solution can be that if, for example, the leno threads are in the tray change, a clamping force is applied to the leno threads.
The aforesaid adverse effects inherent in the last-mentioned device equally occur in the aforesaid leno device, the axis of rotation of which is at an angle of approximately 45 ° to the warp yarns.

Ausgehend von den Unzulänglichkeiten aus dem bekannten Stand der Technik ist es Aufgabe der Erfindung,

  • a) sicherzustellen, daß eine notwendige Dreherfaden-Umlenkung auf dem Wege zwischen der vorbekannten Dreherkantenvorrichtung und den abzubindenden Schußfäden nicht zur Störung der Dreherfaden-Fachbildung führt und
  • b) sicherzustellen, daß bei Fachwechsel der Dreherfäden diese über eine ausreichende Zugspannung verfügen, um eine korrekte Ausbildung des Dreherfadenfaches zu erhalten.
  • Based on the deficiencies of the known prior art, it is an object of the invention
  • a) ensure that a necessary leno thread deflection on the way between the previously known leno selvedge device and the weft threads to be tied does not lead to the disturbance of the leno thread shedding and
  • b) to ensure that when changing the leno threads they have sufficient tension to obtain a correct formation of the leno thread tray.
  • Erfindungsgemäß werden die Aufgaben durch die technischen Merkmale der Ansprüche 1 und 9 gelöst.According to the invention, the objects are characterized by the technical features of Claims 1 and 9 solved.

    Danach ist gemäß Anspruch 1 erfindungswesentlich, daß der rotationssymmetrische Körper, wie dieser zum Umlenken der Dreherfäden erforderlich ist, in wenigstens einer Richtung um seine geometrische Längsachse drehbar ist und mit einem elektromotorischen Antrieb in Wirkverbindung steht.Thereafter, according to claim 1 is essential to the invention that the rotationally symmetrical Body, as this is required for deflecting the leno threads, in at least a direction about its geometric longitudinal axis is rotatable and with an electric motor drive is in active connection.

    Ist der Körper durch einen elektromotorischen Antrieb, der synchron zur Webfachbildung von der Maschinensteuerung angesteuert wird, zwangsläufig angetrieben, ist in vorteilhafter Weise eine Verkordelung der Dreherfäden am Umlenkkörper ausgeschlossen.
    Damit wird eine Dreherfaden-Fachbildung synchron zur Webfachbildung erreicht, ein korrekter Eintrag des Schußfadens gewährleistet und eine Randabbindung der Schußfäden durch die Dreherfäden gesichert.
    If the body is forcibly driven by an electric motor drive, which is controlled by the machine control system in synchronism with the shed formation, it is advantageous to preclude a cabling of the leno threads on the deflection body.
    Thus, a leno thread shed formation is achieved synchronous to the shed formation, ensures a correct entry of the weft and secured a Randabbindung the weft threads through the leno threads.

    Anstelle eines elektromotorischen Antriebs könnte z.B. ein pneumatischer Antrieb in Betracht gezogen werden.Instead of an electromotive drive, e.g. a pneumatic drive in Be considered.

    Im Hinblick auf die Oberflächengestaltung des Umlenkkörpers hat sich als vorteilhaft erwiesen, wenn diese profiliert ausgebildet ist. Es ist von Vorteil, wenn der Körper im Querschnitt als Vielkant ausgebildet ist und eine Oberfläche aufweist, die z.B. einen hohen Reibungswiderstand besitzt.
    Die Oberfläche kann z.B. gummiert sein. Aber auch eine glatte Oberfläche in Verbindung mit dem Vielkantquerschnitt hat sich als vorteilhaft im Zusammenwirken mit den Dreherfäden erwiesen.
    With regard to the surface design of the deflection body has proved to be advantageous if this is formed profiled. It is advantageous if the body is designed as a polygonal cross-section and has a surface which, for example, has a high frictional resistance.
    The surface can be gummed, for example. But even a smooth surface in conjunction with the polygonal cross-section has proven to be advantageous in cooperation with the leno threads.

    Gemäß Anspruch 9 ist den Dreherkantenvorrichtungen eine Dreherfaden-Spanneinrichtung vorgeordnet und zwar zwischen den Dreherfadenspulen und der Dreherkantenvorrichtung selbst.
    Mit einer Spanneinrichtung, die z.B. pneumatischer oder aber mechanischer Wirkungsweise sein kann, wird in vorteilhafter Weise beim Wechsel des Dreherfadenfachs eine Zugspannung auf die Dreherfäden aufgebracht, die die auf einen Fachwechsel folgende Dreherfadenfachbildung korrekt gewährleistet.
    According to claim 9, the leno selvedge devices are preceded by a leno thread tensioning device between the leno thread spools and the leno selvedge device itself.
    With a tensioning device, which may be pneumatic or mechanical action, for example, a tension is applied to the leno threads in an advantageous manner when changing the leno thread tray, which ensures the correct following on a tray change leno thread formation.

    Anhand der Zeichnungen wird die Erfindung beispielhaft erläutert:The invention is explained by way of example with reference to the drawings:

    Bei der in Figur 1 und 2 dargestellten Vorrichtung 1 ist ein insgesamt mit 5 bezeichneter Motor vorgesehen, der eine als Hohlwelle ausgebildete Drehachse 6 besitzt. Die Hohlwelle dient dem Hindurchführen der Dreherfäden 9,10.
    Bei der in Figur 1 dargestellten Ausführungsform, in der die Drehachse 6 quer zu den Kettfäden 11 des zu bildenden Gewebes 12 verläuft, sind zwei Führungselemente 13,14 vorgesehen.
    Jedes Führungselement 13,14 besteht aus zwei Armen 15,16 bzw. 17,18. Die beiden Führungselemente 13,14 verlaufen parallel zueinander und sind am jeweils stirnseitigen Ende der Drehachse eines im Motor 5 integrierten Rotors befestigt, wie sich dies aus Figur 1 deutlich erkennen läßt. Die Arme 15,16 bzw. 17,18 sind endseitig hakenförmig gebogen ausgebildet und weisen im Bereich der hakenförmigen Biegungen die Ösen 19,20 bzw. 21,22 auf. Diese Ösen dienen der Durchführung der Dreherfäden 9,10, die von den Garnspulen 7,8 abgezogen werden. Bei Rotation der Führungselemente 13,14 entsteht im Bereich des Gewebes 12 eine Volldreherkante 2.
    Im Bereich der Zuführung der Dreherfäden 9,10 von den Garnspulen 7,8 erfolgt zwangsläufig eine Verdrillung bzw. Verkordelung der Dreherfäden. Diese Verdrillung wird dadurch wieder aufgehoben, daß die Drehrichtung der Führungselemente 13,14 nach einer bestimmten Anzahl Umdrehungen in der einen Richtung nachfolgend umgekehrt wird.
    Eine Entdrillung der Dreherkante 2 wird hierbei dadurch vermieden, daß zwischen den Dreherfäden 9,10 die Schußfäden 39 einliegen. Das bedeutet, daß auch bei der Entdrillung der Verdrillungen vor dem Führungselement 13 die Bildung der Dreherkante durch Verdrillung mit den betreffenden Schußfäden fortgesetzt wird.
    In the device 1 shown in Figures 1 and 2, a generally designated 5 engine is provided which has a formed as a hollow shaft axis of rotation 6. The hollow shaft serves to pass the leno threads 9, 10.
    In the embodiment shown in Figure 1, in which the axis of rotation 6 extends transversely to the warp threads 11 of the fabric to be formed 12, two guide elements 13,14 are provided.
    Each guide element 13,14 consists of two arms 15,16 and 17,18. The two guide elements 13,14 parallel to each other and are attached to the respective end face of the axis of rotation of a rotor 5 integrated in the motor, as can be clearly seen from Figure 1. The arms 15, 16 and 17, 18 are hook-shaped at the ends and, in the region of the hook-shaped bends, have the eyelets 19, 20 and 21, 22, respectively. These eyelets are used to carry out the leno threads 9,10, which are deducted from the yarn packages 7,8. Upon rotation of the guide elements 13, 14, a full-turn edge 2 is created in the area of the fabric 12.
    In the field of feeding the leno threads 9,10 of the bobbins 7,8 inevitably a twisting or cabling of the leno threads. This twist is canceled by the fact that the direction of rotation of the guide elements 13,14 is subsequently reversed after a certain number of revolutions in one direction.
    A untwisting of the leno selvedge 2 is avoided by inserting the weft threads 39 between the leno threads 9, 10. This means that even with the untwisting of the twists in front of the guide element 13, the formation of the leno selvedge is continued by twisting with the respective weft threads.

    Die Arbeitsweise der Vorrichtung 1 ist nun derart, daß bei beispielsweise einem Motor 5, dessen Rotor eine als Hohlwelle ausgebildete Drehachse 6 besitzt, der Rotor so angetrieben wird, daß seine Drehung mit der Bewegung der in Figur 2 angedeuteten Webschäfte 38 synchronisiert ist, so daß für den Schußfadeneintrag die erforderliche Webfachöffnung und die erforderliche Dreherfachöffnung zur Bildung einer Volldreher-Gewebekante synchron entstehen kann.
    Wahlweise kann durch einen entsprechenden Phasenversatz in der Synchronisation zwischen der Drehbewegung des Rotors und der Webschaftbewegung auch eine zeitlich versetzte Abbindung der Schußfäden erreicht werden. D.h., eine derartige Vorrichtung arbeitet schaftunabhängig im Gegensatz zu Dreherkantenvorrichtungen, die in die Webschäfte eingeordnet sind und mit diesen bewegt werden.
    The operation of the device 1 is now such that, for example, a motor 5, the rotor has a trained as a hollow shaft axis 6, the rotor is driven so that its rotation is synchronized with the movement of the indicated in Figure 2 healds 38, so that for the weft insertion the required shed opening and the required Dreherfachöffnung to form a Volldreher fabric edge can arise synchronously.
    Optionally, by a corresponding phase offset in the synchronization between the rotational movement of the rotor and the heald movement and a staggered setting of the weft threads can be achieved. That is, such a device operates independently of the shaft as opposed to leno edging devices which are arranged in the heald frames and moved with them.

    In Figur 2 ist eine Dreherkantenvorrichtung 1 dargestellt, die einen motorischen Antrieb 5 besitzt und die die gleiche Funktionsweise aufweist, wie die in Figur 1 beschriebene Dreherkantenvorrichtung.
    Die Drehachse 6 des Motors 5 hat hier eine Stellung von etwa 45° zu den Kettfäden 11. Allerdings muß hier eine Dreherfadenführung zwangsläufig über eine Fadenumlenkung erfolgen, um die Dreherfäden 9,10 derart zum Gewebe 12 führen zu können, daß eine Dreherfachbildung ermöglicht wird.
    Zur Fadenumlenkung ist ein nahe des äußeren Kettfadens 11 angeordneter rotationssymmetrischer Körper 23 vorgesehen.
    FIG. 2 shows a leno selvedge device 1 which has a motor drive 5 and which has the same mode of operation as the leno selvedge device described in FIG.
    The axis of rotation 6 of the motor 5 here has a position of about 45 ° to the warp threads 11. However, here a leno thread guide must necessarily take place via a thread deflection in order to lead the leno threads 9,10 to the fabric 12 so that a Dreherfachbildung is made possible.
    For thread deflection, a rotationally symmetrical body 23 arranged close to the outer warp thread 11 is provided.

    In dem Ausführungsbeispiel Figur 1 und 2 ist zwischen den Garnspulen 7,8 und der betreffenden Dreherkantenvorrichtung 1 eine Dreherfaden-Spanneinrichtung platziert, die insbesondere bei Dreherfachwechsel eine der Abzugsrichtung 28 der Dreherfäden 9,10 entgegenwirkende Zugspannung in den Dreherfäden erzeugt.
    Damit wird sichergestellt, daß die Dreherfäden bei Fachwechsel gestrafft sind und nachfolgend eine korrekte Dreherfachbildung erzielt wird.
    Dadurch werden fehlerhafte Schußeinträge, fehlerhafte Schußfaden-Abbindungen und gegebenenfalls Dreherfaden- und Schußfadenbrüche vermieden.
    Dies führt zur Reduzierung von Maschinenabstellungen, zur Reduzierung von Maschinenstillständen und folglich zur Produktivitätssteigerung der Webmaschine.
    In the embodiment of FIGS. 1 and 2, a leno thread tensioning device is placed between the yarn packages 7, 8 and the relevant leno selvedge device 1, which generates a tensile stress in the leno threads counteracting the withdrawal direction 28 of the leno threads 9, in particular in leno sheds.
    This ensures that the leno threads are streamlined when changing subjects and subsequently a correct Dreherfachbildung is achieved.
    As a result, erroneous weft entries, faulty weft thread bindings and possibly leno thread and weft yarn breaks are avoided.
    This leads to the reduction of machine shutdowns, the reduction of machine downtime and consequently the productivity of the loom.

    Bei der Dreherfaden-Spanneinrichtung 26 gemäß der Figur 1 und 2 handelt es sich um eine pneumatisch wirkende Einrichtung. Die Einrichtung ist vorzugsweise in der Ebene der Dreherkantenbildung gelegen, um weitere Dreherfadenumlenkungen auf dem Wege von den Spulen 7,8 zur Dreherkantenbildung am Gewebe 2 zu vermeiden.
    Die Einrichtung 26 selbst besteht aus einem zylindrischen Fadenführungskanal 27 in den, entgegen des Dreherfadenabzugs, die Austrittsöffnung einer Injektordüse 29 mündet.
    Die Injektordüse 29 ist über eine mit einem nicht dargestellten Druckspeicher verbundene Druckleitung 30a mit einer pneumatischen Steuerung 30, umfassend ein elektromagnetisches Stellventil 30b, verbunden.
    Das Stellventil 30b ist über die Steuerleitung 30c mit der speicherprogrammierbaren Steuerung 3 der Webmaschine signalübertragend verbunden.
    Auch der Motor 5 ist über eine Steuerleitung 5a signalübertragend mit der Steuerung 3 verbunden. Damit ist erreichbar, daß wenigstens zeitgleich mit dem Dreherfachwechsel die Dreherfäden 9,10 pneumatisch beaufschlagt werden können und eine entsprechende Zugspannung auf die Dreherfäden erzeugt werden kann.
    The leno thread tensioning device 26 according to FIGS. 1 and 2 is a pneumatically acting device. The device is preferably located in the plane of the leno edging to avoid further leno thread deflections on the way from the spools 7,8 to leno edging on the fabric 2.
    The device 26 itself consists of a cylindrical thread guide channel 27 into which, opposite to the leno thread take-off, the outlet opening of an injector nozzle 29 opens.
    The injector nozzle 29 is connected via a connected to a pressure accumulator, not shown pressure line 30 a with a pneumatic control 30, comprising an electromagnetic control valve 30 b.
    The control valve 30b is signal-transmitting connected via the control line 30c to the programmable logic controller 3 of the loom.
    Also, the motor 5 is connected via a control line 5a signal transmitting to the controller 3. This is achievable that at least simultaneously with the leno change the leno threads 9,10 can be pneumatically acted upon and a corresponding tension can be generated on the leno threads.

    Zum Umlenken der von der Dreherkantenvorrichtung 1 gemäß Figur 2 weggeführten und zum Gewebe 12 hingeführten Dreherfäden 9,10 ist ein rotationssymmetrischer Körper 23 vor den Webschäften 38 und nahe des äußeren Kettfadens 11 angeordnet.
    Figur 3 zeigt den rotationssymmetrischen Körper 23 vergrößert und in Verbindung mit einem Antrieb 25, der z.B. ein elektrisch ansteuerbarer Stellmotor sein kann. Der rotationssymmetrische Körper 23 besitzt einen Vielkantquerschnitt, wie in Figur 4 zu erkennen ist.
    Die von der Dreherkantenvorrichtung 1 gemäß Figur 2 in Richtung Gewebe 12 geführten Dreherfäden 9,10 verdrillen sich gemäß Stand der Technik, wenn sie am Körper 23 nicht den notwendigen Widerstand gegen eine vorzeitige Verdrillung erfahren.
    Aufgrund eines vorhandenen Transportwiderstandes am fadenumlenkenden Körper 23, der gemäß Stand der Technik z.B. eine Rolle oder eine Walze ist, wird also ein Dreherfach nicht ausgebildet und eine Dreherkante nicht erzielt.
    Die vorzeitige Verdrillung der Dreherfäden 9',10' ist hier schematisch durch die unterbrochene Linie 9',10', nach der Umlenkung der Dreherfäden 9',10' am Körper 23 verdeutlicht.
    Durch die erfindungsgemäße Querschnittsgestaltung und/oder einer entsprechenden Oberflächenausbildung im Zusammenhang mit einer drehenden Lagerung oder einem Drehantrieb für den Körper 23 ist eine Dreherfachbildung durch die Dreherkantenvorrichtung gemäß Figur 2 sichergestellt.
    For deflecting the leno threads 9,10 guided away from the leno selvedge device 1 according to FIG. 2 and guided to the fabric 12, a rotationally symmetrical body 23 is arranged in front of the heddle shafts 38 and close to the outer warp thread 11.
    FIG. 3 shows the rotationally symmetrical body 23 enlarged and in connection with a drive 25, which may be, for example, an electrically controllable servomotor. The rotationally symmetrical body 23 has a polygonal cross section, as can be seen in FIG.
    The leno threads 9, 10 guided in the direction of the fabric 12 by the leno selvedge device 1 according to FIG. 2 twist according to the prior art if they do not experience the necessary resistance against premature twisting on the body 23.
    Due to an existing transport resistance on the thread-deflecting body 23, which according to the prior art, for example, a roller or a roller, so a leno compartment is not formed and a leno edge is not achieved.
    The premature twisting of the leno threads 9 ', 10' is here schematically illustrated by the broken line 9 ', 10', after the deflection of the leno threads 9 ', 10' on the body 23.
    Due to the cross-sectional configuration according to the invention and / or a corresponding surface formation in connection with a rotating mounting or a rotary drive for the body 23, a leno formation is ensured by the leno selvedge device according to FIG.
