Abstract

Description

Die Erfindung betrifft eine Vorrichtung zum Bilden einer Dreherkante, wobei wechselseitig bewegte Webschäfte vorgesehen sind, mit mindestens zwei Hebelitzen und eine durch die Hebelitzen geführte und von jeweils der einen Hebelitze mitgenommenen Halblitze.The invention relates to a device for forming a leno selvedge, wherein mutually moving heald frames are provided, with at least two lifting healds and a half heald that is guided through the lifting healds and carried along by one lifting heald.

Eine bekannte Vorrichtung zum Bilden einer Dreherkante besteht aus zwei Hebelitzen und einer Halblitze und einer Steuerungsvorrichtung für die Halblitze (FR-OS 2273893). Hierbei sind die Hebelitzen unmittelbar an den wechselseitig bewegten Webschäften angeordnet. Die Steuerungsvorrichtung für die Halblitze besteht aus einer Litzentragschiene, die durch eine Feder gehalten wird, die an der Webmaschine befestigt ist.A known device for forming a leno edge consists of two lifting healds and a half heald and a control device for the half heald (FR-OS 2273893). The lifting healds are arranged directly on the reciprocating heald frames. The control device for the half heald consists of a heald support rail which is held by a spring which is attached to the weaving machine.

Nachteilig bei dieser Vorrichtung zum Bilden einer Dreherkante ist zum einen das hohe Gewicht der Steuerungsvorrichtung für die Halblitze, bestehend aus Litzentragschiene und Feder. Denn das hohe Gewicht der gesamten Vorrichtung stellt eine natürliche Grenze für eine Erhöhung der Hubzahl dar, weil die kinetische Energie bei der Beschleunigung und Abbremsung der Massen zu groß wird.A disadvantage of this device for forming a leno edge is, on the one hand, the high weight of the control device for the half strands, consisting of a strand support rail and spring. Because the high weight of the entire device represents a natural limit for an increase in the number of strokes, because the kinetic energy during acceleration and deceleration of the masses is too large.

Es hat sich weiterhin als nachteilig herausgestellt, daß während der gesamten Hubbewegung einer Hebelitze, die von dieser Hebelitze mitgenommene Halblitze ständig unter der Einwirkung der Kraft der Feder der Litzentragschiene steht. Hierdurch verschleißen die Hebelitzen im Bereich der Führungsöffnungen für die Halblitzen extrem schnell.It has also been found to be disadvantageous that during the entire lifting movement of a lifting heald, the half-heald carried along by this lifting heald is constantly under the action of the force of the spring of the heald support rail. This causes the lifting strands to wear out extremely quickly in the area of the guide openings for the half strands.

Der Erfindung lag daher die Aufgabe zugrunde, eine Vorrichtung zum Bilden einer Dreherkante zu schaffen, die leichter ist, als die bekannte Vorrichtung und bei der darüber hinaus ein geringerer Verschleiß an den Hebelitzen auftritt.The invention was therefore based on the object of providing a device for forming a leno edge which is lighter than the known device and in which less wear on the lifting strands also occurs.

Dies wird erfindungsgemäß dadurch erreicht, daß zur Steuerung der Halblitze durch die Hebelitzen Steuerungsmittel vorgesehen sind. Die Halblitze besteht im wesentlichen aus zwei Schenkeln, die an ihrem einen Ende eine geschlossene Öse zur Führung des Dreherfadens bilden. Jeder Schenkel der Halblitze wird durch eine in der Hebelitze angeordneten Führungsöffnung geführt, die durch zwei seitlich übereinander versetzt angeordnete Stege gebildet wird. Die bekannten Mittel zur Steuerung der Halblitze, nämlich Litzentragschiene mit Feder sind hierbei also nicht mehr erforderlich; mithin fallen auch die mit diesen Mitteln einhergehenden Nachteile weg.This is achieved according to the invention in that control means are provided for controlling the half strands through the lifting strands. The half-strand consists essentially of two legs, which form a closed eyelet at one end for guiding the leno thread. Each leg of the half-strand is guided through a guide opening arranged in the lifting strand, which is formed by two webs which are laterally offset one above the other. The known means for controlling the semi-heddles, namely braid support rail with spring are no longer required here; consequently, the disadvantages associated with these means also disappear.

So ist insbesondere bedingt durch das überaus geringe Gewicht der gesamten Vorrichtung eine Steigerung der Hubzahl möglich.An increase in the number of strokes is possible in particular due to the extremely low weight of the entire device.

Ein welterer Vorteil besteht darin, daß eine Vielzahl von Hebelitzen nebeneinander an den Webschäften befestigt werden kann. Nach dem vorbekannten Stand der Technik konnten maximal vier Litzen nebeneinander an den Webschäften befestigt werden. Andernfalls mußte die Federkraft erhöht werden. Darüber hinäus steht einer Erhöhung der Anzahl der Litzen nach dem vorbekannten Stand der Technik das vorhandene Platzangebot auf der Litzentragschiene für die Halblitze entgegen.A further advantage is that a large number of lifting healds can be attached to the heald frames side by side. According to the prior art, a maximum of four strands could be attached to the heald frames side by side. Otherwise the spring force had to be increased. In addition, an increase in the number of strands according to the known state of the art prevents the available space on the strand support rail for the half strands.

Nach einer besonders vorteilhaften Ausführungsform sind die Mittel zur Steuerung der Halblitze in den Hebelitzen angeordneten Magnete.According to a particularly advantageous embodiment, the means for controlling the half strands are magnets arranged in the lifting strands.

Hierbei entspricht der Abstand der in der Hebelitzen angeordneten Magnete von dem innenliegenden Steg der Führungsöffnung in etwa der Schenkellänge der Halblitze. Um die Magnetkraft zur Steuerung aufbauen zu können, muß die Halblitze aus einem magnetischen Metall bestehen, oder eine entsprechende Einlage aufwelsen. Selbst bei hoher Hubzahl gewährleistet diese Vorrichtung immer eine exakte Steuerung der Halblitze.Here, the distance of the magnets arranged in the lifting healds from the inner web of the guide opening corresponds approximately to the leg length of the half heald. In order to be able to build up the magnetic force for control, the half strands must consist of a magnetic metal, or a corresponding insert must be rubbed on. Even with a high number of strokes, this device always ensures precise control of the half strands.

Vorteilhaft ist weiterhin, daß hierbei der Verschleiß an dem innenliegenden Steg der Führungsöffnung einer Hebelitze durch die während der Mitnahme auf den Steg der Halblitze wirkende Kraft nur gering ist, da im Gegensatz zu der bekannten Ausführungsform einer Steuerung mit Litzentragschiene und Feder, dieser Steg der Führungsöffnung der Hebelitze nur zum Zeitpunkt der Einleitung der Umkehrbewegung unter der Einwirkung der durch die Magnete hervorgerufenen Kraft steht. Die Einwirkung der Gewichtskraft der Halblitze auf den Verschließ des Steges ist hierbei vernachlässigbar gering.It is also advantageous that the wear on the inner web of the guide opening of a lifting wire is only slight due to the force acting on the web of the half-wire during driving, since in contrast to the known embodiment of a control with a heddle support rail and spring, this web of the guide opening the leverage is only under the influence of the force caused by the magnets at the time the reversal movement is initiated. The effect of the weight of the half strands on the closure of the web is negligible.

Nach einer weiteren Unterform zu der zweiten Ausführungsform ist die Halblitze mit den Hebelitzen bzw. den Webschäften selbst zur Steuerung durch elastische Mittel, z.B. Gummizüge verbunden. Gegenüber der vorbekannten Vorrichtung zum Bilden einer Dreherkante weist auch diese Vorrichtung ein um ein Vielfaches vermindertes Gewicht auf. Der innenliegende Steg der Führungsöffnung der Hebelitze steht zwar während der gesamten Bewegung der Hebelitze unter der Last dieser elastischen Mittel, doch ist die dadurch hervorgerufene Kraft um ein Vielfaches geringer, als die auf den Steg einwirkende Kraft bei der bekannten Steuerungsvorrichtung, bestehend aus Litzentragschiene und Feder, da die Gummizüge, eben bedingt durch das geringe Gewicht, auch geringer dimensioniert sein können.According to a further sub-form to the second embodiment, the half heald with the lifting healds or the heald frames is itself to be controlled by elastic means, e.g. Elastic bands connected. Compared to the previously known device for forming a leno edge, this device also has a weight that is many times lower. The inner web of the guide opening of the lifting heald is under the load of these elastic means during the entire movement of the lifting heald, but the force caused thereby is many times smaller than the force acting on the web in the known control device, consisting of a heddle support rail and spring , because the elastic bands, due to the low weight, can also be dimensioned smaller.

Fig. 2
shows an embodiment in which the control of the half heald is carried out by elastic cables arranged on the lifting healds;
Fig. 3

Fig. 4
shows an embodiment in which the control of the half heald is carried out by elastic bands arranged on the heald frames.

Gemäß den Figuren 1 bis 4 sind die Hebelitzen jeweils mit 1 und 2 bezeichnet, die von den Hebelitzen geführte Halblitze jeweils mit 3. Die Hebelitzen 1 und 2 weisen endseitig Mittel 4a bis 4d zur Befestigung an den wechselseitig bewegten Webschäften 5a bis 5d auf. Jede Hebelitze 1 bzw. 2 besitzt eine Führungsöffnung 6, 7 auf, die durch die Stege 6a, 6b bzw. 7a, 7b gebildet wird. Die Halblitze 3 besteht im wesentlichen aus zwei Schenkeln 3a und 3b, die an ihrem oberen Ende eine geschlossene öse 8 zur Führung des Dreherfadens 19 bilden.According to FIGS. 1 to 4, the lifting healds are each designated 1 and 2, the half healds guided by the lifting healds are each designated 3. The lifting healds 1 and 2 have end means 4a to 4d for attachment to the mutually moving heald frames 5a to 5d. Each lifting heald 1 or 2 has a guide opening 6, 7 which is formed by the webs 6a, 6b or 7a, 7b. The half-strand 3 consists essentially of two legs 3a and 3b, which form a closed eyelet 8 for guiding the leno thread 19 at their upper end.

Nach der in Fig. 1 dargestellten ersten Ausführungsform erfolgt die Steuerung durch in dem Mantel 20, 21 der Hebelitzen 1, 2 angeordnete Magnete 9, 10. Die Mitnahme der Halblitze 3 selbst erfolgt durch jeweils den die Halblitze 3 im Bereich der öse 8 erfassenden innenliegenden Steg 6b bzw. 7b der Führungsöffnung 6 bzw. 7. Um eine einwandfreie Steuerung und Mitnahme der Halblitze durch die Hebelitzen zu gewährleisten, beträgt der Abstand zwischen dem Magneten 9 bzw. 10 und dem innenliegenden Steg 6b bzw. 7b einer jeden Führungsöffnung 6 bzw. 7 etwa der Länge eines Schenkels 3a, 3b der Halblitze 3.According to the first embodiment shown in FIG. 1, the control is carried out by magnets 9, 10 arranged in the jacket 20, 21 of the lifting healds 1, 2 Web 6b or 7b of the guide opening 6 or 7. In order to ensure proper control and entrainment of the half strands by the lifting strands, the distance between the magnets is 9 or 10 and the inner web 6b or 7b of each guide opening 6 or 7 approximately the length of a leg 3a, 3b of the half-strand 3.

Anstelle der Magnete sind nach einer zweiten Ausführungsform zur Steuerung Gummizüge 11, 12 vorgesehen, durch die die Schenkel 3a, 3b der Halblitze mit den Hebelitzen verbunden sind. Der Steuerungsvorgang selbst entspricht hierbei dem der ersten Ausführungsform.Instead of the magnets, according to a second embodiment, for control purposes, elastic bands 11, 12 are provided, by means of which the legs 3a, 3b of the half strand are connected to the lifting strands. The control process itself corresponds to that of the first embodiment.

Bei der Ausführungsform gemäß Fig. 3 erfolgt die Steuerung lediglich durch die auf der Halblitze 3 einwirkende Schwerkraft und die entsprechende Vorspannung des durch die öse 8 der Halblitze 3 geführten Dreherfadens. Die Führung und Mitnahme der Halblitze erfolgt hierbei wiederum durch die Stege 6b bzw. 7b der Führungsöffnungen 6 bzw. 7.In the embodiment according to FIG. 3, the control takes place only through the force of gravity acting on the half-strand 3 and the corresponding pretensioning of the leno thread guided through the eyelet 8 of the half-strand 3. The guiding and entrainment of the half strands takes place in turn through the webs 6b and 7b of the guide openings 6 and 7, respectively.

Die Ausführungsform gemäß 4 unterscheidet sich von der gemäß Fig. 2 lediglich dadurch, daß hierbei die Gummizüge 13, 14 durch Klemmittel 15, 16 unmittelbar mit den Webschäften 5c, 5d verbunden sind.The embodiment according to FIG. 4 differs from that according to FIG. 2 only in that the elastic bands 13, 14 are directly connected to the heald frames 5c, 5d by clamping means 15, 16.

Um den schon geringen Verschleiß an den innenliegenden Stegen 6b bzw. 7b noch weiter zu vermindern, weisen diese Stege Verstärkungseinlagen 17, 18, z.B. aus Metall auf.In order to further reduce the already slight wear on the inner webs 6b and 7b, these webs have reinforcing inserts 17, 18, e.g. made of metal.
