Abstract

Device for forming a gauze edge, consisting of alternately moved sheds, a yarn-guide device being attached to one shed, and there being arranged on the other shed a needle holder which has two parallel essentially U-shaped frame rails and which holds a yarn-guide element, the frame rail (3, 4) having an insert on its side facing the yarn-guide element (5). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Bilden einer Dreherkante, bestehend aus wechselseitig bewegten Webschäften, wobei an einem Webschaft eine Fadenführungseinrichtung angebracht ist und wobei an dem anderen Webschaft ein zwei parallele im wesentlichen U-förmig ausgebildete Gestell­schienen aufweisender Nadelhalter angeordnet ist, der ein Fadenführungselement hält.The invention relates to a device for forming a leno selvedge consisting of mutually moving heald frames, a thread guide device being attached to one heald frame and a needle holder having two parallel, essentially U-shaped frame rails, which holding a thread guide element, is arranged on the other heald frame.

Eine Vorrichtung der eingangs genannten Art ist beispielsweise aus dem deutschen Gebrauchsmuster 79 31 872 bekannt. Es hat sich gezeigt, daß diese Gestellschienen einem hohen Verschleiß unterworfen sind, und zwar insbesondere dann, wenn die im dem Fadenführungselement angeordneten Magnete unmittelbar mit der Gestellschiene in Berührung kommen. Sind die Gestellschienen eines Nadelhalters soweit verschlissen, daß das Fadenführungselement nicht mehr ordnungsgemäß geführt wird, so daß die Gefahr von Bindefehlern entsteht, muß der komplette Nadelhalter ausgetauscht werden, was teuer ist.A device of the type mentioned is known for example from German utility model 79 31 872. It has been shown that these frame rails are subject to high wear, in particular when the magnets arranged in the thread guide element come into direct contact with the frame rail. If the frame rails of a needle holder are worn out to such an extent that the thread guide element is no longer properly guided, so that there is a risk of binding errors, the entire needle holder must be replaced, which is expensive.

Der Erfindung liegt daher die Aufgabe zugrunde einen Nadelhalter zu schaffen, der einem geringeren Verschleiß unterliegt. Dies wird erfindungsgemäß dadurch erreicht, daß die Gestellschiene auf ihrer dem Fadenführungselement zugewandten Seite eine Einlage, z.B. eine Metallschiene aufweist.The object of the invention is therefore to create a needle holder which is subject to less wear. This is achieved according to the invention in that the frame rail has an insert, for example a metal rail, on its side facing the thread guide element.

Durch diese Maßnahme wird ein Verschleiß an den Gestell­schienen selbst vermieden; ist die Metallschiene verschlissen, so kann diese problemlos ausgetauscht werden. Zur Fixierung der Metallschiene in den Gestellschienen, ist jeweils in Schenkelgrund eines Schenkels der U-förmig ausgebildeten Gestellschiene eine Nut angeordnet, die der Aufnahme und Führung der Metallschiene dient.This measure prevents wear on the rack rails themselves; if the metal rail is worn, it can be replaced without any problems. To fix the metal rail in the frame rails, a groove is arranged in each leg base of one leg of the U-shaped frame rail, which is used to receive and guide the metal rail.

Da zur magnetischen Abbremsung des Fadenführungselementes die Gestellschiene immer metallisch ausgebildet sein muß, konnten Gestellschienen aus Kunststoff nicht zum Einsatz kommen. Durch den Einsatz der Metallschiene in die Gestellschiene kann nunmehr auch eine Gestellschiene aus Kunststoff zum Einsatz kommen; die magnetische Abbremsung des Fadenführungselementes erfolgt nunmenr in Zusammenarbeit mit der Metallschiene. Gestellschienen aus Kunststoff haben den Vorteil des geringeren Gewichts, wodurch sich die Möglichkeit eröffnet, die Hubzahl einer Webmaschine zu erhöhen.Since the frame rail must always be made of metal for magnetic braking of the thread guide element, frame rails made of plastic could not be used. By using the metal rail in the frame rail, a frame rail made of plastic can now also be used; the magnetic braking of the thread guide element is now carried out in cooperation with the metal rail. Frame rails made of plastic have the advantage of lower weight, which opens up the possibility of increasing the number of strokes of a weaving machine.

Metallschienen, die nach dem Stand der Technik zum Schutz gegen Rost lediglich vernickelt sind, haben darüber hinaus den Nachteil, daß sie beim Einsatz in der Naßweberei schnell Rost ansetzen. Das ist bei Gestellschienen aus Kunststoff ausgeschlossen. Die Metallschiene selbst besteht aus rostfreiem aber magnetischem Stahl.Metal rails, which according to the prior art are only nickel-plated for protection against rust, also have the disadvantage that they quickly become rusty when used in wet weaving. This is impossible with plastic frame rails. The metal rail itself is made of rustproof but magnetic steel.

In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt.

  • Fig. 1 zeigt die Vorrichtung zum Bilden einer Dreherkante in einer Seitenansicht;
  • Fig. 2 zeigt die zwei parallelen Gestellschienen eines Nadelhalters im Schnitt, wobei die Nadeln weggelassen sind.
An example embodiment is shown in the drawing.
  • Fig. 1 shows the device for forming a leno edge in a side view;
  • Fig. 2 shows the two parallel frame rails of a needle holder in section, the needles being omitted.

Gemäß Fig. 1 besteht eine Vorrichtung zum Bilden einer Dreher­kante aus wechselseitig bewegten Webschäften, wobei an dem einen Webschaft ein Nadelhalter angeordnet ist, und der andere Webschaft eine Fadenführungseinrichtung aufweist. Zur besseren Übersicht ist in Fig. 1 der zweite Webschaft mit der daran angeordneten Fadenführungseinrichtung weggelassen worden.1, a device for forming a leno selvedge consists of reciprocating heald frames, a needle holder being arranged on one heald frame and the other heald frame having a thread guiding device. For a better overview, the second heald frame with the thread guide device arranged thereon has been omitted in FIG. 1.

Gemäß Fig. 1 ist der insgesamt mit 1 bezeichnete Nadelhalter an den Webschaft 2 angeordnet. Der Nadelhalter 1 besteht aus den zwei parallelen Gestellschienen 3 und 4, die der Führung des Fadenführungselementes 5 dienen (Fig. 2). Die im wesentlichen U-förmig ausgebildete Gestellschiene 3, 4 weist im Schenkelgrund eines jeden Schenkels eine Nut 6 bzw. 7 auf. In den Nuten 6 bzw. 7 befindet sich die Metallschiene 8 bzw. 9. Das in den beiden Gestellschienen 3, 4 geführte Fadenführungselement 5 steht somit nicht unmittelbar mit den Gestellschienen in Berührung, sondern liegt beidseitig an den Metallschienen 8, 9 an. Sind die Metallschienen verschlissen, so können diese in einfacher Weise durch neue ersetzt werden.1, the needle holder, designated overall by 1, is arranged on the heald frame 2. The needle holder 1 consists of the two parallel frame rails 3 and 4, which serve to guide the thread guide element 5 (FIG. 2). The substantially U-shaped frame rail 3, 4 has a groove 6 and 7 in the leg base of each leg. The metal rails 8 and 9 are located in the grooves 6 and 7 respectively. The thread guide element 5 guided in the two frame rails 3, 4 is therefore not in direct contact with the frame rails, but is in contact with the metal rails 8, 9 on both sides. If the metal rails are worn, they can easily be replaced with new ones.
