Abstract

Each reed (10, 20) includes a magnet (18, 28) near the upper end. Polarity of the magnets is such that they attract. The reeds have upper and lower limbs (11, 21, 12, 22) and attachments (13, 23, 14, 24), with the magnets located in the upper transitions between them. A stop (19) is located in the transition between the upper limb (11) and the attachment (13), the magnet being located in the stop. The other reed has an offset (29) in the same location, with the magnet (28) arranged in the offset. Each lifter has a slot (12a, 22a) receiving a limb (31, 32) of the half-reed (30). At the slots, further magnets are arranged, in either attracting- or repelling orientations. Below the lower magnets, a rest (17, 27) is provided for the foot of the half-reed, matching its shape. The lower magnets are smaller than the upper magnets.

Description

Die Erfindung betrifft eine Vorrichtung zum Bilden einer Dreherkante, umfassend zwei Hebelitzen und eine Halblitze, wobei die Hebelitzen am oberen und unteren Ende jeweils ein Befestigungselement aufweisen, wobei die Hebelitzen im Bereich des unteren Endes für den Fuß der Halblitze mindestens einen Magnet aufweisen.The invention relates to a device for forming a leno selvedge, comprising two lifting healds and a half heald, wherein the haul hitches on upper and lower end each having a fastener, wherein the lifting healds in the area of the lower end for the foot of the half heald have at least one magnet.

Eine in der DE 297 03 896 U1 beschriebene Dreherkantenvorrichtung der eingangs genannten Art besteht, wie bereits ausgeführt, aus zwei Hebelitzen und einer jeweils wechselweise von der einen Hebelitze mitgenommenen Halblitze. Die Hebelitzen selbst sind an Litzentragschienen der Webschäfte oder an den Webschäften selbst angebracht. Eine Halblitze zeichnet sich durch eine im Prinzip U-förmige Gestalt auf, wobei die beiden Schenkel am oberen Ende in eine Öse zur Führung des Steherfadens übergehen. Die Schenkel der Halblitze besitzen am unteren Ende einen Halblitzenfuß. Die Hebelitzen selbst zeichnen sich durch zwei Schenkel aus, nämlich einen unteren und einen oberen Schenkel, wobei endseitig eine jede Hebelitze ein Befestigungselement zur Aufnahme durch die Litzentragschiene bzw. den Webschaft zeigt. Der untere Schenkel ist hierbei mit einem Schlitz zur Führung des Schenkels der Halblitze versehen. Im unteren Bereich des unteren Schenkels sind zu beiden Seiten des Schlitzes übereinander angeordnete Magnete vorgesehen, die zum einen der Abbremsung der Halblitze beim Übergang der Halblitze von der einen Hebelitze zur anderen Hebelitze dienen, und darüber hinaus den Zweck haben, die Halblitze jeweils zu steuern. Unter Steuern wird hierbei verstanden, dass die Halblitze sicher von der sie jeweils mitnehmenden Hebelitze erfasst wird. Der Dreherfaden läuft wechselweise rechts oder links zwischen dem Schenkel der Halblitze und dem Schenkel der entsprechenden Hebelitze entlang. Bei dieser aus dem Stand der Technik bekannten Dreher-kantenvorrichtung, bei der jeweils am unteren Ende der Hebelitzen Magnete vorgesehen sind, war die Polung der Magnete derart, dass die beiden Hebelitzen sich abstoßen. Die Folge hiervon ist, dass die beiden Hebelitzen einer Dreherkantenvorrichtung x-beinig zueinander stehen. Infolge dieser x-beinigen Stellung steht auch die Halblitze unter Spannung. Die Halblitze hat in diesem Fall das Bestreben, nach oben zu wandern. Das bedeutet, dass insbesondere dann, wenn der Steherfaden reißt, die Gefahr besteht, dass innerhalb kürzester Zeit bei schnelllaufenden Webmaschinen, d. h. bei Maschinen mit sehr hoher Schusszahl, die Halblitze nicht mehr von den Magneten gehalten wird, sondern aufsteigt und schlussendlich von der Hebelitze nicht mehr erfasst werden kann und schlussendlich in die Maschine fällt. Wenn die Maschine nicht unmittelbar gestoppt werden kann, weil z. B. der Fadenbruch nicht sofort bemerkt wird, kann dies zu erheblichen Schäden an der Maschine führen. Die oben beschriebenen Gefahren bestehen insbesondere, wie bereits ausgeführt, bei schnelllaufenden Maschinen. Allerdings sind derartige Phänomene auch schon bei Maschinen festgestellt worden, die nur mit mäßigen Schusszahlungen arbeiten. A leno selvedge device described in DE 297 03 896 U1 The aforementioned type consists, as already stated, of two lifting healds and one each alternately taken from the one lifting heald Half heald. The lifting healds themselves are on heald bars of the heald frames or attached to the healds themselves. A half-light is emerging by a basically U-shaped shape, wherein the two legs on pass the upper end into an eyelet to guide the stance thread. The Legs of the half-heald have at the lower end a Halblitzenfuß. The Healdles themselves are characterized by two legs, namely one lower and an upper leg, with each end a lever heald one Fastening element for receiving through the Litzentragschiene or the Weaving shaft shows. The lower leg is in this case with a slot for Guide the thigh of half-heald provided. At the bottom of the lower leg are on either side of the slot on top of each other arranged magnets provided, on the one hand, the deceleration of Half flashes at the transition of the half heald from one heald to the other Heald serve, and beyond the purpose of having the half heald each to control. Under control is understood here that the half-heald safely is detected by the respective lifting heald. The leno thread runs alternately right or left between the thigh of the half-heald and the leg of the corresponding lifting heald along. At this off known in the art leno-edge device, in each case At the lower end of the hoist magnets are provided, was the polarity the magnets in such a way that the two lifting seats repel each other. The episode of this is that the two lifting seats of a leno device are x-legged to stand by each other. As a result of this x-legged position is also the Half flash under tension. The half flash has in this case the effort to hike up. This means that especially if the Ground thread breaks, there is a risk that within a short time high-speed weaving machines, d. H. in machines with very high Number of shots, the half-lightning is no longer held by the magnets, but rises and finally no longer detected by the huckle and finally falls into the machine. When the machine can not be stopped immediately because z. B. the thread breakage not Immediately noticed, this can cause significant damage to the machine to lead. The above-described risks exist in particular, such as already executed, in high-speed machines. However, such are Phenomena have already been detected in machines that only with moderate shot payments work.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Dreherkantenvorrichtung der eingangs genannten Art bereitzustellen, bei der eine x-förmige Stellung der Hebelitzen einer Dreherkantenvorrichtung vermieden wird.The invention is therefore based on the object, a leno selvedge device of the type mentioned above, in which an x-shaped Position of the heald of a leno device avoided becomes.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass jede Hebelitze im Bereich des oberen Endes mindestens einen Magneten aufweist, wobei die Polung der Magnete der beiden Hebelitzen einer Dreherkantenvorrichtung derart ist, dass diese sich anziehen. Ist sichergestellt, dass die beiden Hebelitzen einer Dreherkantenvorrichtung bereits im Bereich des oberen Endes mit ihren Stirnseiten aneinander anliegen, dann besteht auch im unteren Bereich nur eine geringe Gefahr, dass diese in die bereits zuvor genannte x-förmige Stellung übergehen. Insbesondere wenn dann auch die Magnete im unteren Bereich der Hebelitze, also im Übergangsbereich vom unteren Schenkel zum Befestigungselement eine Polung derart aufweisen, dass sich auch hier die Hebelitzen einer Dreherkantenvorrichtung anziehen, ist eine derartige x-förmige Ausrichtung der Hebelitzen in der zuvor beschriebenen Weise nicht zu befürchten. Das bedeutet, dass selbst bei hoher Schusszahl die Schenkel der Hebelitzen einer Dreherkantenvorrichtung immer parallel zueinander verlaufen, mithin die Gefahr des Aufsteigens der Halblitze selbst bei gebrochenem Steherfaden vermieden wird, und auch die Belastung der Halblitze aufgrund der parallelen Ausrichtung der Hebelitzen wesentlich geringer ist.The object is achieved in that each lifting heald in Has the region of the upper end at least one magnet, wherein the Polarity of the magnets of the two lifting seats of a leno device such is that they dress. Is ensured that the two Lifting a leno device already in the area of the upper End with their front sides abut each other, then there is also in the lower range only a small risk that this in the previously pass over the x-shaped position mentioned above. Especially if then the Magnets in the lower area of the lifting heald, ie in the transition area from lower leg to fastener have a polarity such that also attract the heald of a leno device here, is such an x-shaped orientation of the lifting healds in the above not to be feared. That means that even at high number of shots the legs of the lifting heald one Dreherkantenvorrichtung always parallel to each other, thus the Risk of rising of the half-heald even with broken ground thread avoided, and also the burden of half heal due to the parallel Alignment of the lifting seats is much lower.

Es hat sich weiterhin herausgestellt, dass insbesondere die Folgeschäden von aus der Dreherkantenvorrichtung herausgefallener Halblitzen wesentlich vermindert werden konnten.It has also been found that in particular the consequential damages of fallen out of the leno device halflitzen essential could be reduced.

Weitere vorteilhafte Merkmale sind den Unteransprüchen zu entnehmen.Further advantageous features can be found in the dependent claims.

So ist insbesondere vorgesehen, dass eine Hebelitze im Bereich des Übergangs von dem oberen Schenkel zu dem Befestigungselement einen Anschlag aufweist, wobei der mindestens eine Magnet in dem Anschlag angeordnet ist. Dieser Anschlag dient als Begrenzung für die Litzentragschiene bzw. den Webschaft, um eine stabile Befestigung der Hebelitze an dem Webschaft bzw. der Litzentragschiene zu gewährleisten. Die andere Hebelitze besitzt im Bereich des Übergangs von dem oberen Schenkel zum Befestigungselement eine Abkröpfung, wobei der mindestens eine Magnet in der Abkröpfung angeordnet ist. Daraus wird deutlich, dass die im oberen Bereich der jeweiligen Hebelitze angeordneten Magnete durchaus nur einen geringen Abstand aufweisen, so dass diese schlussendlich dafür sorgen können, dass die Hebelitzen aufgrund der Anziehungskraft der Magnete immer aneinander anliegen.Thus, it is provided in particular that a lifting heald in the region of Transition from the upper leg to the fastener a Stop, wherein the at least one magnet in the stop is arranged. This stop serves as a limitation for the Litzentragschiene or the heald to a stable attachment of To ensure heald on the heald or the heddle support rail. The other lifting heald has in the area of the transition from the upper one Leg to the fastener a bend, the at least a magnet is arranged in the bend. It is clear that the in the upper region of the respective lifting heald magnets arranged quite have only a small distance, so that this ultimately can make sure that the lifting healds due to the attraction of the Magnets always abut each other.

Weiterhin ist nach einem weiteren Merkmal der Erfindung vorgesehen, dass jede Hebelitze im unteren Schenkel einen Schlitz zur Aufnahme eines Schenkels der Halblitze aufweist, wobei die Hebelitze zu beiden Seiten des Schlitzes im Bereich des Übergangs vom unteren Schenkel zu dem Befestigungselement übereinander jeweils zwei Magnete aufweist, wobei die Polung der Magnete einer jeden Hebelitze einer Dreherkantenvorrichtung derart ist, dass sich die Magnete der beiden Hebelitzen anziehen. Das heißt, dass nicht nur im oberen Bereich der Hebelitzen die Hebelitzen einander anziehen, sondern auch im unteren Bereich, mithin in jedem Fall eine parallele Ausrichtung der Hebelitzen gewährleistet ist.Furthermore, it is provided according to a further feature of the invention that each heald in the lower leg has a slot for receiving a Has thighs of the half heald, the heald heald on both sides of the Slot in the region of the transition from the lower leg to the Fastener has one above the other two magnets each, wherein the Polarity of the magnets of each lifting heald of a leno device such is that attract the magnets of the two lifting heald. This means, that not only in the upper region of the lifting heald healds each other but also in the lower part, therefore in any case one parallel alignment of the lifting heald is ensured.

Durch die oben beschriebene Art der Anordnung der Magnete, insbesondere im Hinblick auf deren Polung, wird weiterhin erreicht, dass sich zwei benachbarte Dreherkantenvorrichtungen mit zwei Hebelitzen abstoßen. Das heißt, entsprechend der Magnetkraft besteht zwischen zwei benachbarten Hebelitzen immer ein Abstand, der verhindert, dass die Hebelitzen einer Dreher-kantenvorrichtung an den Hebelitzen einer benachbarten Dreherkantenvorrichtung reiben. Diese Reibung und ein damit einhergehender Verschleiß wird weitgehend vermieden.By the type of arrangement of the magnets described above, in particular in terms of their polarity, it is further achieved that two repel neighboring leno edging devices with two lifting healds. The means, according to the magnetic force exists between two adjacent Hooes always have a distance that prevents the hawkers from a Turner-edge device on the lifting seats of an adjacent leno selvedge device rub. This friction and a concomitant Wear is largely avoided.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, dass die Ausrichtung der Polung der beiden unteren Magnetpaare unterschiedlich ist, so dass sich in Verbindung mit dem Fuß der Halblitze, der, wie die gesamte Halblitze, aus magnetisierbarem Material besteht, ein geschlossener Magnetkreis ergibt. Die unteren Magnete können hierbei kleiner sein, als die darüber angeordneten Magnete, da diese lediglich die Aufgabe der zusätzlichen Sicherung der Halblitze gegen Durchschlagen auf die Hebelitzen besitzen. Das heißt, die beiden im unteren Bereich, d. h. im unteren Schenkel der Hebelitze angeordneten Magnete dienen zum einen der Abbremsung der Halblitze derart, dass sie den Fuß der Halblitze erfassen, und die Halblitze in ihrer Bewegung hierdurch abbremsen bzw. des Weiteren den Fuß der Halblitze auch festhalten, um auf die Halblitze steuernd einzuwirken beim der Übergang von der einen Hebelitze auf die andere Hebelitze.According to a further feature of the invention it is provided that the Orientation of the polarity of the two lower magnet pairs is different, so in conjunction with the foot of the half-heald, like the whole Halfleaf, made of magnetisable material, a closed one Magnetic circuit yields. The lower magnets can be smaller than the above arranged magnets, since these only the task of additional securing of the half heald against penetration on the Own heald. That is, the two at the bottom, d. H. in the lower legs of the heald arranged magnets serve for a the braking of the half heald so that they the foot of the half heald capture, and the half-heald in this way slow down or the Continue to hold the foot of the half-healer to the half-heald acting on the transition from the one hone to the steering other lifting healds.

Des Weiteren ist unter den im unteren Schenkel angeordneten Magneten ein Bett für den Fuß der Halblitze vorgesehen, das in seiner Form dem unteren Ende des Fußes der Halblitze entspricht. Dieses Bett dient schlussendlich der Aufnahme und Abbremsung der Halblitze dann, wenn die Magnetkraft, aus welchen Gründen auch immer nicht ausreichend sein sollte, um die Halblitze beim Übergang von der einen Hebelitze zur anderen Hebelitze abzubremsen.Furthermore, one of the magnets arranged in the lower leg is a Bed provided for the foot of the half-heald, which in its form the lower End of the foot corresponds to the half flashes. This bed finally serves the absorption and deceleration of the half heald when the magnetic force, for whatever reason should not be sufficient to the Half-lightning at the transition from one lifting heald to the other lifting heald decelerate.

Die Dreherkantenvorrichtung 1 umfasst die beiden Hebelitzen 10 und 20, sowie die Halblitze 30. Jede Hebelitze 10, 20 zeigt einen oberen Schenkel 11, 21 sowie einen unteren Schenkel 12, 22, wobei sich an jeden Schenkel ein Befestigungselement 13, 23 bzw. 14, 24 anschließt, mit dessen Hilfe die Hebelitzen an den Litzentragschienen der Webmaschine befestigt sind. Die Hebelitzen 10, 20 nehmen die mit 30 bezeichnete Halblitze auf. Das Prinzip der Herstellung einer Dreherkante mit einer Dreherkantenvorrichtung, umfassend Hebe- und Halblitzen, ist hinreichend bekannt. In diesem Zusammenhang wird auf die DE 38 18 680 C1 oder das DE 297 038 96 U1 verwiesen, die beide die Art der Herstellung einer Dreherkantenvorrichtung beschreiben. Die Halblitze 30 besitzt die beiden Schenkel 31, 32 mit den endseitigen Füßen 31 a, 32a. Die Hebelitze 10, 20 zeigt jeweils im Bereich des Schlitzes 12a bzw. 22a einen Sitz 12b bzw. 22b, auf dem die Halblitze mit dem U-förmigen Ende (Pfeil 34) im Bereich der Öse 35 für den Steherfaden aufsitzt. Die Länge des Schenkels 31 bzw. 32 korreliert hierbei mit dem Abstand von dem Sitz 12b bzw. 22b zu den beiden Magneten 15, 16 bzw. 25, 26 insofern, als diese den Fuß 31 a bzw. 32a der Halblitze 30 erfassen müssen. Die Anordnung der Magnete 15, 16 bzw. 25, 26 ergibt sich anschaulich aus der Fig. 2; hierbei ist erkennbar, dass die oberen beiden Magnete 15, 25 größer sind als die unteren beiden Magnete 16, 26; was noch wesenlicher ist: es sind die beiden Magnetpaare jeweils gegensinnig gepolt. Dies bewirkt in Verbindung mit dem Fuß 31 a bzw. 32a der Halblitze einen geschlossenen Magnetkreis, was sich insbesondere in Bezug auf die Abbremsung der Halblitze beim Eintauchen in die sie jeweils mitnehmende Hebelitze als sehr vorteilhaft insofern herausgestellt hat, als hierdurch die Halblitze nachhaltig abgebremst wird. Für den Fall, dass die Magnetkraft nicht für die Abbremsung der Halblitze vollständig ausreichend sein sollte, ist unter dem Magneten 16, 26 jeweils ein Bett 17, 27 vorgesehen, das dreieckförmig ausgebildet ist, korrespondierend zu der Ausbildung des unteren Endes der Füße 31a, 32a der Halblitze 30. Die Funktion dieses Bettes 17, 27 besteht ausschließlich darin, die Halblitze abzufangen, so dass diese nicht mit ihrem oberen Ende im Bereich des Pfeiles 34 auf den Sitz 12b bzw. 22b aufschlägt.The leno edge device 1 comprises the two lifting healds 10 and 20, and the half heald 30. Each heald 10, 20 shows an upper leg 11, 21 and a lower leg 12, 22, wherein each leg a fastener 13, 23 and 14, 24 connects, with the help of the Heald hitches are attached to the heald carrier rails of the loom. The Lifting healds 10, 20 receive the half-healds designated 30. The principle the production of a leno selvedge with a leno selvedge device, comprising lifting and half-strands, is well known. In this Relation is to DE 38 18 680 C1 or DE 297 038 96 U1 both refer to the manner of making a leno selvedge device describe. The half heald 30 has the two legs 31, 32 with the end feet 31 a, 32 a. The lifting heald 10, 20 respectively in the area of the slot 12a and 22a, a seat 12b and 22b, on which the half heald with the U-shaped end (arrow 34) in the eyelet 35 for the Steherfaden seated. The length of the leg 31 and 32 correlates in this case with the distance from the seat 12b or 22b to the two magnets 15, 16 or 25, 26 in so far as this the foot 31 a and 32 a of the half heald 30th need to capture. The arrangement of the magnets 15, 16 and 25, 26 results clearly from the Fig. 2; Here it can be seen that the upper two Magnets 15, 25 are larger than the lower two magnets 16, 26; What even more important is: there are two pairs of magnets in each case in opposite directions poled. This causes in conjunction with the foot 31 a and 32 a of the half heald a closed magnetic circuit, which is particularly in relation to the Deceleration of the half heald when immersed in the each entraining Heald has proved to be very advantageous insofar as this Halflitze sustained braked. In the event that the magnetic force is not completely sufficient for the deceleration of the half heald is under the magnet 16, 26 each have a bed 17, 27 is provided, the is formed triangular, corresponding to the formation of the lower end of the feet 31a, 32a of the half heald 30. The function of this Bed 17, 27 consists solely in intercepting the half heald so that this not with its upper end in the region of the arrow 34 on the seat 12b or 22b hits.

Wesentlich ist nun, dass durch die Ausrichtung der Magnete 15, 16 der einen Hebelitze und korrespondierend hierzu die Ausrichtung der Magnete 25, 26 der anderen Hebelitze 20 die beiden Hebelitzen 10, 20 durch diese Magnete 15, 25 bzw. 16, 26 angezogen werden. Betrachtet man in diesem Zusammenhang das obere Ende der Hebelitzen 10, 20, so ist erkennbar, dass auch dort Magnete 18, 28 vorgesehen sind; so ist der Magnet 18 im Bereich des Anschlages 19, und der Magnet 28 im Bereich der Abkröpfung 29 angeordnet. Auch hier ist die Polung der Magnete 18 und 28 derart gewählt, dass diese sich anziehen. Als Ergebnis der Ausrichtung der Magnete ist festzuhalten, dass die Hebelitzen durch die Anziehung am oberen und am unteren Ende in jedem Fall parallel zueinander stehen und nicht wie beim Stand der Technik eine gegebenenfalls x-förmige Stellung aufweisen, wie dies der Fall ist, wenn sich die Magnete im unteren Bereich abstoßen.It is essential that by the orientation of the magnets 15, 16 of the one Lifting heald and corresponding to the orientation of the magnets 25, 26th the other lifting heald 20, the two lifting healds 10, 20 by these magnets 15, 25 and 16, 26 are attracted. Looking at this If the upper end of the lifting healds 10, 20 is connected, it can be seen that that magnets 18, 28 are also provided there; so is the magnet 18 in Area of the stop 19, and the magnet 28 in the region of the bend 29 arranged. Again, the polarity of the magnets 18 and 28 is such chosen that they dress. As a result of the orientation of the Magnets is to be noted that the lifting healds by the attraction at upper and lower ends in each case are parallel to each other and not an optionally x-shaped position as in the prior art as is the case when the magnets are in the lower region repel.

Im Einzelnen ergibt sich die Polung der Magnete aus den Fig. 4a, 4b und 5a, 5b. Insbesondere ist hieraus auch erkennbar, dass sich bei zwei benachbarten Dreherkantenvorrichtungen, umfassend jeweils zwei Hebelitzen und eine Halblitze, die Hebelitzen der jeweils einen Dreherkantenvorrichtung von denen der benachbarten Dreherkantenvorrichtung aufgrund der Polung der Magnete abstoßen. Das heißt, es ist sichergestellt, dass die Hebelitzen zweier benachbarter Dreherkantenvorrichtungen in keinem Fall aneinander reiben, was den Verschleiß wesentlich vermindert.In detail, the polarity of the magnets results from FIGS. 4a, 4b and 5a, 5b. In particular, it can also be seen that at two adjacent leno edging devices, each comprising two Healdles and a half-heald, the hawks each one Dreherkantenvorrichtung of those of the adjacent Repel leno device due to the polarity of the magnets. The means, it is ensured that the heald of two adjacent In no case rubbing leno devices together, which the Wear significantly reduced.
