Description

Die Erfindung betrifft eine Bandwebmaschine gemäss Oberbegriff des Anspruches 1.The invention relates to a ribbon loom according to the preamble of claim 1.

Eine Bandwebmaschine der eingangs genannten Art ist aus der DE-B 24 00 101 bekannt. Bei dieser Bandwebmaschine ist die Öffnungsebene des Längsschlitzes der Eintragnadel quer zur Bewegungsebene der Eintragnadel angeordnet und der Haken liegt innerhalb des Längsschlitzes an einem Rand eines Schenkels der den Längsschlitz bildenden Schenkel. Obwohl mit der Eintragnadel bereits sehr gute Ergebnisse erzielt werden, hat sie jedoch den Nachteil, dass zur sicheren Einlegung eines oder mehrerer der Schussfäden Stecher erforderlich sind, die den oder die Schusfäden führen. Ausserdem ergibt sich der Nachteil, dass der Schussfaden von dem Haken abspringen kann. Durch die Anordnung des Hakens innerhalb des Längsschlitzes ist es überdies erforderlich, dass die Eintragnadel eine relativ grosse Breite aufweisen muss, was wiederum ein relativ grosses Webfach notwendig macht. Die zum Öffnen des Webfaches notwendigen grösseren Wege der entsprechenden Schäfte erfordern entsprechend grössere Antriebe, deren Drehzahl begrenzt ist. Damit sind der Leistung einer solchen Bandwebmaschine Grenzen gesetzt.A ribbon loom of the type mentioned is known from DE-B 24 00 101. In this ribbon loom, the opening plane of the longitudinal slot of the insertion needle is arranged transversely to the plane of movement of the insertion needle and the hook lies within the longitudinal slot on an edge of one leg of the legs forming the longitudinal slot. Although very good results have already been achieved with the insertion needle, it has the disadvantage, however, that piercers which guide the weft thread or threads are required for the safe insertion of one or more of the weft threads. In addition, there is the disadvantage that the weft thread can jump off the hook. The arrangement of the hook within the longitudinal slot also makes it necessary for the insertion needle to have a relatively large width, which in turn makes a relatively large shed necessary. The larger paths of the corresponding shafts required to open the shed require correspondingly larger drives, the speed of which is limited. This limits the performance of such a ribbon loom.

Aufgabeder Erfindung ist es, eine Bandwebmaschine der eingangs genannten Art so auszubilden, dass die erwähnten Nachteile vermieden werden.The object of the invention is to design a ribbon loom of the type mentioned in the introduction in such a way that the disadvantages mentioned are avoided.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Dadurch, dass der Haken ausserhalb des Längsschlitzes der Eintragnadel angeordnet ist und mindestens annähernd in der Bewegungsebene der Eintragnadel gegen die Fadenführer gerichtet liegt, begrenzt der Haken die Öffnung des Längsschlitzes nicht, sodass letzterer wesentlich schmäler ausgeführt werden kann, wobei allein auf die Führung des oder der Schussfäden Rücksicht zu nehmen ist. Ein schmälerer Längsschlitzführt wiederum zu einer schmäleren Eintragnadel, wodurch das Webfach nicht mehr so weit geöffnet werden muss und man deshalb mit kleineren Wegen der entsprechenden Schäfte auskommt. Dies führt wiederum zu kleineren und schnelleren Antrieben, wodurch die Leistung einer solchen Bandwebmaschine erhöht werden kann. Die Anordnung des Hakens ausserhalb des Längsschlitzes und in Richtung auf die Fadenführer sowie die exakte Führung der Schussfäden innerhalb des Längsschlitzes ermöglichen es, dass auf Stecher in einer solchen Bandwebmaschine verzichtet werden kann und dennoch eine sichere Funktion der Eintragnadel dank der besseren Fadenführung gewährleistet ist. Damit wird aber auch ein Abspringen der oder der Schussfäden von dem Haken der Eintragnadel vermieden.Because the hook is arranged outside the longitudinal slot of the insertion needle and is directed at least approximately in the plane of movement of the insertion needle against the thread guide, the hook does not limit the opening of the longitudinal slot, so that the latter can be made much narrower, solely on the guidance of the or consideration must be given to the weft threads. A narrower longitudinal slot in turn leads to a narrower insertion needle, which means that the shed no longer has to be opened so far and therefore the smaller shafts of the corresponding shafts are sufficient. This in turn leads to smaller and faster drives, which can increase the performance of such a ribbon loom. The arrangement of the hook outside of the longitudinal slot and in the direction of the thread guide as well as the exact guidance of the weft threads within the longitudinal slot make it possible to dispense with setters in such a ribbon weaving machine and yet a reliable function of the insertion needle is ensured thanks to the better thread guidance. This also prevents the weft thread (s) from jumping off the hook of the insertion needle.

Vorteilhafte Ausgestaltungen der Bandwebmaschine sind in den Ansprüchen 2 bis 5 beschrieben.Advantageous embodiments of the ribbon loom are described in claims 2 to 5.

Die Öffnungsebene des Längsschlitzes der Eintragnadel kann bei der neuen Anordnung des Hakens in der Bewegungsebene der Eintragnadel liegen. Dadurch ergibt sich eine besonders flache Ausgestaltung der Eintragnadel, was wiederum ein besonders kleines Webfach zur Folge hat und damit sehr hohe Leistungen der Bandwebmaschinen ermöglicht. Allerdings erfahren die Schussfäden im Längsschlitz eine sehr straffe Führung, sodass dem Kreuzen eines einzulegenden Schussfadens mit einem in Auswahlstellung befindlichen Schussfaden Grenzen gesetzt sind. Es sind auch Zwischenstufen der Ausbildung der Eintragnadel möglich, bei denen die Öffnungsebene des Längsschlitzes einen Winkel zwischen 0° und 90° zur Bewegungsebene der Eintragnadel bildet. Besonders vorteilhaft ist jedoch eine Ausbildung der Bandwebmaschine nach Anspruch 3, da hier die Schussfäden im Längsschlitz leichter kreuzen können. Dabei kann der Haken am unteren oder oberen Schenkel der Eintragnadel angeordnet sein, je nachdem, ob die Fadenführer beim Wandern in die Auswahlstellung nach unten oder oben bewegt werden.With the new arrangement of the hook, the opening plane of the longitudinal slot of the insertion needle can lie in the plane of movement of the insertion needle. This results in a particularly flat design of the insertion needle, which in turn results in a particularly small shed and thus enables very high performance of the ribbon looms. However, the weft threads are guided very tightly in the longitudinal slot, so that there are limits to the crossing of a weft thread to be inserted with a weft thread in the selection position. Intermediate stages of the formation of the insertion needle are also possible, in which the opening plane of the longitudinal slot forms an angle between 0 ° and 90 ° to the plane of movement of the insertion needle. However, a design of the ribbon loom according to claim 3 is particularly advantageous, since here the weft threads can cross more easily in the longitudinal slot. The hook can be arranged on the lower or upper leg of the insertion needle, depending on whether the thread guides are moved down or up when hiking into the selection position.

Eine besonders schmale und stabile Ausbildung der Eintragnadel ergibt sich durch die Ausbildung nach Anspruch 4. Dies ermöglicht es, den hakenfreien Schenkel der Eintragnadel nach Anspruch 5 weiter auszugestalten.A particularly narrow and stable design of the insertion needle results from the design according to claim 4. This makes it possible to further develop the hook-free leg of the insertion needle according to claim 5.

  • FIG. 5 shows another insertion needle in a representation similar to that in FIG. 3.

Die Webmaschine weist eine auf einem Maschinengestell 2 angeordnete Auflageplatte 4 auf, die zur Auflage und Führung der gewebten Ware 6 dient. Am vorderen Ende der Auflageplatte schliesst sich ein Brustbaum 8 an, über den die gewebte Ware zu einem nicht näher dargestellten Warenbaum geführt wird. Das rückwärtige Ende der Auflageplatte 4 dient zur Führung und Halterung der Ware an der Anschlagkante 12, von der die Kettfäden 14 über eine Fachbildevorrichtung 16 zu einer nicht näher dargestellten Kettfadenliefervorrichtung führen.The weaving machine has a support plate 4 arranged on a machine frame 2, which serves to support and guide the woven goods 6. At the front end of the support plate is a breast beam 8, via which the woven fabric is guided to a fabric tree, not shown. The rear end of the support plate 4 is used for guiding and holding the goods on the stop edge 12, from which the warp threads 14 lead via a shedding device 16 to a warp thread delivery device, not shown.

Das Maschinengestell 2 enthält eine nicht näher dargestellte Antriebsvorrichtung, die eine Welle 18 oszillierend antreibt, an der ein Arm 20 angeordnet ist, der eine Schussfaden-Eintragnadel 22 trägt. Die Eintragnadel 22 dient zur Eintragung eines oder mehrerer Schussfadenschlaufen 24 in das durch die Kettfäden 14 gebildete Webfach 26. Auf der der Eintragnadel 22 gegenüberliegenden Seite des Webfaches 26 ist eine hin- und hergehend angetriebene Wirknadel angeordnet, die zum Abbinden der eingetragenen Schussfadenschlaufen 24 dient. Dabei können aufeinanderfolgende Schussfadenschlaufen mit sich selbst und/oder mit einem Hilfsfaden verwirkt und abgebunden werden. Ein an einem Schwenkarm 30 angeordnetes Webblatt 32 dient zum Anschlagen der eingetragenen Schussfadenschlaufen an der Anschlagkante.The machine frame 2 contains a drive device, not shown, which drives an oscillating shaft 18 on which an arm 20 is arranged which carries a weft insertion needle 22. The insertion needle 22 serves to insert one or more weft loops 24 into the shed 26 formed by the warp threads 14. On the side of the shed 26 opposite the insertion needle 22 there is a back and forth driven knitting needle arranged, which serves to bind the weft loops 24 entered. Successive weft loops can be forfeited and tied with themselves and / or with an auxiliary thread. A reed 32, which is arranged on a swivel arm 30, serves to attach the inserted weft thread loops to the stop edge.

Die Eintragnadel 22 enthält einen Längsschlitz 34, dessen Öffnungsebene quer zur Bewegungsebene der Eintragnadel liegt. Dieser Längsschlitz wird durch zwei Schenkel gebildet, wobei der obere Schenkel 36 einen rechteckigen Querschnitt aufweist, dessen Hauptachse in der Bewegungsebene liegt. An dem oberen Schenkel 36 ist nahe des freien Endes der Eintragnadel 22 durch eine absatzweise Verjüngung 38 ein Haken 40 gebildet, dessen Spitze 42 gegen das freie Ende der Eintragnadel 22 weist und gegen rückwärtige Fadenführer 44a, 44b, für Schussfäden 46a, 46b, gerichtet ist.The insertion needle 22 contains a longitudinal slot 34, the opening plane of which lies transversely to the plane of movement of the insertion needle. This longitudinal slot is formed by two legs, the upper leg 36 having a rectangular cross section, the main axis of which lies in the plane of movement. On the upper leg 36, near the free end of the insertion needle 22, a hook 40 is formed by a step-by-step taper 38, the tip 42 of which points towards the free end of the insertion needle 22 and is directed against rear thread guides 44a, 44b, for weft threads 46a, 46b .

Der untere, den Längsschlitz 34 begrenzende Schenkel 48 der Eintragnadel 22 ist schwächer und vorzugsweise aus einem Draht 50 gebildet. In dem Längsschlitz 34 können mehrere Schussfäden 46a, 46b, geführt sein, im vorliegenden Falle sind nur zwei dargestellt. In Ruhestellung der Fadenführer 44a, 44b, liegen die Schussfäden 46a, 46b, am unteren Rand des Längsschlitzes 34, d. h. am unteren Schenkel 48 an, wie dies in Figur 3 und insbesondere in Figur 4 für den Schussfaden 46b dargestellt ist. Dadurch liegen die Schussfäden 46a, 46b, ausserhalb des Eingriffsbereiches des Hakens 40. Wird nun ein Fadenführer 44a und/oder 44b (Fadenführer 44a in Figur 4) in die Auswahlstellung angehoben, so wird auch der entsprechende Schussfaden 46a und/oder 46b (Schussfaden 46a in Figur 4) schräg nach oben geführt, wodurch er in den Eingriffsbereich des Hakens 40 gelangt. Der jeweils erfasste Schussfaden wird von der Eintragnadel 22 in Form einer Schlaufe in das Webfach 26 eingelegt und auf der gegenüberliegenden Seite mittels der Wirknadel 28 festgehalten und abgebunden.The lower leg 48 of the insertion needle 22 delimiting the longitudinal slot 34 is weaker and is preferably formed from a wire 50. A plurality of weft threads 46a, 46b can be guided in the longitudinal slot 34, in the present case only two are shown. In the rest position of the thread guides 44a, 44b, the weft threads 46a, 46b lie at the lower edge of the longitudinal slot 34, i.e. H. on the lower leg 48, as shown in FIG. 3 and in particular in FIG. 4 for the weft thread 46b. As a result, the weft threads 46a, 46b lie outside the engagement area of the hook 40. If a thread guide 44a and / or 44b (thread guide 44a in FIG. 4) is now raised into the selection position, the corresponding weft thread 46a and / or 46b (weft thread 46a in Figure 4) led obliquely upwards, whereby it reaches the engagement area of the hook 40. The weft thread recorded in each case is inserted into the shed 26 by the insertion needle 22 in the form of a loop and is held and tied on the opposite side by means of the knitting needle 28.

Für die Auswahl des jeweils in das Webfach 26 einzutragenden Schussfadens aus einer Mehrzahl der in dem Längsschlitz 34 geführten Schussfäden 46a, 46b können irgendwelche programmierbare Vorrichtungen vorgesehen sein, so z. B. eine Nockenvorrichtung oder dergleichen. Die Auswahl kann aber auch durch die Fachbildevorrichtung, beispielsweise eine Schaftmaschine, eine Einzellitzensteuerung oder eine Jacquardmaschine erfolgen. Letztere ist im vorliegenden Beispiel dargestellt und man erkennt deren Litzenbündel 50, welches durch eine mit Löchern versehenes Chorbrett 52 geführt ist.Any programmable devices can be provided for the selection of the weft thread to be inserted into the shed 26 from a plurality of the weft threads 46a, 46b guided in the longitudinal slot 34. B. a cam device or the like. The selection can also be made by the shedding device, for example a dobby, a single strand control or a jacquard machine. The latter is shown in the present example and its strand bundle 50 can be seen, which is led through a choir board 52 provided with holes.

Die Figur 5 zeigt ein weiteres Ausführungsbeispiel einer Schussfaden-Eintragnadel 54, die im Gegensatz zur Schussfaden-Eintragnagel 22 der Figuren 3 und 4 einen Längsschlitz 56 aufweist, dessen Öffnung in der Bewegungsebene der Eintragnadel 54 liegt. An dem rückwärtigen, den Längsschlitz 56 einseitig bestimmenden Schenkel 58 ist ein Haken 60 angeordnet, deranalog dem Haken 40 der Eintragnadel 22 angeordnet und ausgebildet ist. Der vordere, den Längsschlitz 56 begrenzende Schenkel 62 der Eintragnadel 54 ist ebenfalls schwächer ausgebildet, wie dies auch bei der Eintragnadel 22 der Fall ist. Die Funktion dieser Eintragnadel 54 bezüglich des Eintragens der Schussfäden 46a und/oder 46b entspricht dem bereits oben beschriebenen Arbeitsablauf.FIG. 5 shows a further exemplary embodiment of a weft insertion needle 54 which, in contrast to the weft insertion nail 22 of FIGS. 3 and 4, has a longitudinal slot 56, the opening of which lies in the plane of movement of the insertion needle 54. On the rear leg 58, which defines the longitudinal slot 56 on one side, there is a hook 60 which is arranged and designed analogously to the hook 40 of the insertion needle 22. The front leg 62 of the insertion needle 54 delimiting the longitudinal slot 56 is also weaker, as is also the case with the insertion needle 22. The function of this insertion needle 54 with respect to the insertion of the weft threads 46a and / or 46b corresponds to the workflow already described above.

Es sind noch weitere Ausgestaltungen der Eintragnadel möglich. So sind zum Beispiel Mischformen zwischen den Eintragnadeln 22 und 54 denkbar, d. h. die Öffnungsebene des Längsschlitzes kann gegebenenfalls in einem zwischen 0° und 90° schwankenden Winkel zur Bewegungsebene der Eintragsnadel angeordnet sein. Ausserdem ist es keinenfalls erforderlich, dass die Eintragnadel gebogen ist. Es sind auch gerade Nadeln mit gradlinig hin- und hergehenden Bewegungen möglich.

Further configurations of the entry needle are also possible. For example, mixed forms between the entry needles 22 and 54 are conceivable, ie the opening plane of the longitudinal slot can optionally be arranged at an angle which fluctuates between 0 ° and 90 ° to the plane of movement of the entry needle. In addition, it is not necessary that the stylus is bent. Straight needles with straight back and forth movements are also possible.
