Webmaschinen, die zum Herstellen von Drehergeweben eingerichtet sind, sind in der Praxis in einer Reihe unterschiedlicher Ausführungsformen bekannt. So ist bspw. in der Druckschrift WO 98/07913 eine Vorrichtung zum Steuern der Kettfäden beim Herstellen eines Drehergewebes in einer Textilmaschine beschrieben. Unter Drehergeweben sind dabei Gewebe verstanden, die zumindest teilweise in der sogenannten Schling- oder Dreherbindung gearbeitet sind, die sich von anderen Bindungen dadurch unterscheidet, dass bei ihr die Kettfäden nicht parallel nebeneinander verlaufen, sondern, dass zwei oder mehrere Kettfäden sich miteinander umschlingen. Einzelheiten dieser Webbindung sind bspw. beschrieben in „Die Weberei" Fachbuchverlag GmbH, Leipzig, 1951, Seite 311 ff. Um Drehergewebe herzustellen müssen die Steher- und Dreherfäden der Webkette quer zu der Kettfadenrichtung sowohl in der Webebene als quer zu dieser bewegt werden, wozu es bekannt ist zwei in Kettfadenrichtung hintereinander angeordnete Riete oder Schäfte zu verwenden, die mit Lamellen oder Nadeln versehen sind, durch deren Ösen die Fäden gezogen sind. Die Steherfäden passieren, vom Webblatt aus gesehen, das eine Nadelriet durch dessen Nadelaugen, während die Dreherfäden durch die Nadelaugen des zweiten Nadelriets gezogen sind, das auf der Kettfadenseite des ersten Nadelriets angeordnet ist. Durch diese Anordnung wird erreicht, dass die Steherfäden durch die Bewegung des ersten, dem Webblatt benachbarten Nadelriets mitbewegt werden, während die Dreherfäden die Bewegungen des zweiten Nadelriets mitmachen. Durch entsprechende Relativbewegungen der beiden Nadelriete zueinander erfolgt einerseits die gegenseitige Verschlingung der Steherund Dreherfäden und andererseits die Fachbildung für den Schussfadeneintrag.Weaving machines which are set up to produce leno fabrics are known in practice in a number of different embodiments. For example, WO 98/07913 describes a device for controlling the warp threads when producing a leno fabric in a textile machine. In this context, leno fabrics are understood to mean fabrics that are at least partially worked in the so-called loop or leno weave, which differs from other weaves in that the warp threads do not run parallel to one another, but rather that two or more warp threads loop around each other. Details of this weave weave are described, for example, in "Die Weberei" Fachbuchverlag GmbH, Leipzig, 1951, page 311 ff. In order to produce leno fabrics, the upright and leno threads of the warp chain must be moved transversely to the warp thread direction both in the weaving plane and transversely to it, for what purpose it is known to use two reeds or shafts arranged one behind the other in the warp thread direction and provided with lamellas or needles, through the eyes of which the threads are pulled in. The upright threads, seen from the reed, pass a needle reed through the needle eyes, while the leno threads pass through The needle eyes of the second needle reed, which is arranged on the warp thread side of the first needle reed, are drawn in. This arrangement ensures that the upright threads are moved along by the movement of the first needle reed, which is adjacent to the reed, while the leno threads join in the movements of the second needle reed. Corresponding relative movements of the two needle reeds to one another result in the interlacing of the upright and leno threads on the one hand and the formation of the shed thread insertion on the other hand.
Bei den bekannten Vorrichtungen und Webmaschinen zur Herstellung von Drehergeweben sind die Antriebseinrichtungen zur Erzeugung der Bewegungen der Führungsmittel der Steher- und der Dreherfäden durchweg kompliziert und aufwendig. Es sind häufig Antriebs- und Steuermechanismen vorgesehen, die eine verhältnismäßig große Massenträgheit der bewegten Teile aufweisen, wodurch die Arbeitsgeschwindigkeit beeinträchtigt wird.In the known devices and weaving machines for the production of leno fabrics, the drive devices for generating the movements of the guide means of the upright and leno threads are consistently complicated and expensive. Drive and control mechanisms are often provided which have a relatively high mass inertia of the moving parts, as a result of which the working speed is impaired.
Aufgabe der Erfindung ist es deshalb eine Webmaschine zu schaffen, die unabhängig von der Art des Schussfadeneintrags (d.h. durch Webschützen, Greifer, Luftdüsen, u.s.f.) sich dadurch auszeichnet, dass die Bewegungen der Führungsmittel für die Steher- und die Dreherfäden auf eine sehr einfache betriebsichere Weise mit geringem konstruktivem Aufwand erzeugt werden.The object of the invention is therefore to provide a weaving machine which, regardless of the type of weft insertion (ie by shooters, grippers, air nozzles, etc.), is characterized in that the movements of the guide means for the upright and leno threads are very simple and reliable Be generated with little design effort.
Zur Lösung dieser Aufgabe ist die eingangs genannte Webmaschine dadurch gekennzeichnet, dass der Antrieb der Führungsmittel für die Steherfäden und/oder der Führungsmittel für die Dreherfäden von den Antriebsmitteln der Weblade abgeleitet ist.To achieve this object, the weaving machine mentioned at the outset is characterized in that the drive of the guide means for the upright threads and / or of the guide means for the leno threads is derived from the drive means of the sley.
Die Webmaschine braucht damit nicht unbedingt über besondere Fachbildungsorgane oderThe weaving machine therefore does not necessarily need special training bodies or
Hilfsmittel wie Innentritt oder die sogenannte Exzenter- oder Schaftmaschine mit eigenem oder fremdem Antrieb zu verfügen. Die Bewegungen der Führungsmittel für die Herstellung von Drehergeweben werden weitgehend unmittelbar von in der Webmaschine an sich vorhandenen Antriebsquellen abgeleitet.To have tools such as an internal kick or the so-called eccentric or dobby with its own or third-party drive The movements of the guide means for the production of leno fabrics are largely derived directly from drive sources which are present in the weaving machine.
Der Einsatz des Webladenantriebs für den Antrieb der Führungsmittel der Steher- und/oder Dreherfäden erlaubt eine massearme Konstruktion und gewährleistet gleichzeitig einen präzisen Seitenwechsel der Steherfäden zu den Dreherfäden, in exakter zwangsläufiger Abstimmung auf die Schussfadenanschlagbewegung der Weblade. Bei Verwendung von Lamellen- oder Nadelrieten als Führungsmittel für die Steher- und/oder die Dreherfäden lassen sich diese Riete im Hinblick auf eine gelegentlich erforderlich werdende Kettfadenbruchbehebung sehr bedienungsfreundlich anordnen, während andererseits die Verstellung der Hubweiten der Lamellen- oder Nadelriete konstruktiv einfach und bedienungsleicht zu realisieren ist.The use of the shutter drive for driving the guide means of the upright and / or leno threads allows for a low-mass construction and at the same time guarantees a precise change of side of the upright threads to the leno threads, in exact inevitable coordination with the weft thread movement of the sley. When using lamellar or needle reeds as guiding means for the upright and / or leno threads, these reeds can be very useful with regard to an occasionally necessary removal of warp threads Arrange in a user-friendly manner, while on the other hand the adjustment of the stroke widths of the slat or needle reed can be implemented in a structurally simple and easy-to-use manner.
Die quer zu der Webebene gerichtete Bewegung der Führungsmittel für die Steher- und oder Dreherfäden kann über die zugeordneten Antriebsmittel von einer eine oszillierende Drehbewegung ausführenden Antriebswelle, der sogenannten Webblattwelle der Webladenantriebsmittel, abgeleitet sein. Auch hat es sich als vorteilhaft erwiesen, wenn die Führungsmittel für die Steher- und/oder die Dreherfäden um eine Drehachse schwenkbar gelagert sind, die durch eine drehbar gelagerte Welle gebildet ist, welche mit der Webblattwelle der Webladenantriebsmittel getrieblich gekuppelt ist.The movement of the guide means for the upright and / or leno threads directed transversely to the weaving plane can be derived via the assigned drive means from a drive shaft which carries out an oscillating rotational movement, the so-called reed shaft of the shutter drive means. It has also proven to be advantageous if the guide means for the upright and / or leno threads are pivotally mounted about an axis of rotation which is formed by a rotatably mounted shaft which is coupled to the reed shaft of the shutter drive means.
Bei der Ausbildung der Führungsmittel als Lamellen- oder Nadelriet kann dieses zwischen zwei Stellungen verschwenkbar sein, von denen es in der einen Stellung im Wesentlichen parallel zu dem Lamellen- oder Nadelriet der jeweils anderen Führungsmittel ausgerichtet ist und in der anderen Stellung quer zu der Webebene gegenüber dem erstgenannten Nadelriet um einen die Größe des Webfaches bestimmenden Betrag angehoben ist.When the guiding means are designed as lamellar or needle reeds, this can be pivoted between two positions, of which in one position it is aligned essentially parallel to the lamellar or needle reeds of the respective other guiding means and in the other position opposite to the weaving plane the first-mentioned needle reed is raised by an amount determining the size of the shed.

In Fig 1 ist im Ausschnitt ein sogenanntes Drehergewebe dargestellt, das aus Steherfäden 1, Dreherfäden 2 und Schussfäden 300 besteht. Dabei sind im oberen Teil a) der Abbildung die Steherfäden 1 im gestreckten Zustand veranschaulicht während der untere Abschnitt b) den tatsächlichen Verlauf der Steherfäden 1 und der Dreherfäden 2 wiedergibt. Ersichtlich sind die Dreherfäden 2 um die Steherfäden 1 herumgeschlungen.In Fig. 1, a so-called leno fabric is shown in the detail, which consists of upright threads 1, leno threads 2 and weft threads 300. In the upper part a) of the figure, the upright threads 1 are illustrated in the stretched state, while the lower section b) shows the actual course of the upright threads 1 and the leno threads 2. As can be seen, the leno threads 2 are wrapped around the upright threads 1.
Um das Drehergewebe nach Fig. 1 zu erzeugen, müssen die Steherfäden 1 und die Dreherfäden 2 bei der Fachbildung relativ zueinander quer zu der Kettfadenrichtung bewegt werden, so dass die Dreherfäden 2 die Steherfäden 1 in der aus Fig. 1 ersichtlichen Weise umschlingen.In order to produce the leno fabric according to FIG. 1, the upright threads 1 and the leno threads 2 have to be moved relative to one another transversely to the warp thread direction during the formation of the shed, so that the leno threads 2 loop around the upright threads 1 in the manner shown in FIG. 1.
Die dazu erforderlichen Bewegungsverhältnisse sind in dem Diagramm nach Fig. 2 veranschaulicht. Sie bilden die Grundlage der im Nachfolgenden in verschiedenen Ausführungen beschriebenen erfindungsgemäßen Webmaschine. Sie werden deshalb kurz erläutert:The movement relationships required for this are illustrated in the diagram according to FIG. 2. They form the basis of the weaving machine according to the invention described below in various versions. They are therefore briefly explained:
Die zum Erzeugen der Dreherbindung erforderliche gegenseitige Bewegung der Steherfäden 1 und der Dreherfäden 2 kann auf drei verschiedene Arten geschehen, die in Fig. 2 in den drei übereinander liegenden Diagrammen wiedergegeben sind und von denen jede Art eine besondere Ausbildung der Antriebsmittel für die Führungsmittel der Steher- und der Dreherfäden 1 bzw. 2 erfordert.The mutual movement of the upright threads 1 and the leno threads 2 required to produce the leno binding can be done in three different ways, which are shown in FIG. 2 in the three superimposed diagrams and each of which has a special design of the drive means for the guide means of the upright - And the leno threads 1 and 2 are required.
Prinzipiell gilt, dass nach jedem Schusseintrag und Webblattanschlag die das Drehergewebe bildenden Steher- und/oder Dreherfäden, bezogen auf die Webebene, in vertikaler und horizontaler Richtung bewegt werden müssen. Hierbei liegt die Webebene ungefähr in der horizontalen Richtung des jeweiligen Diagramms. Der Bewegungsablauf dieser das Drehergewebe bildenden Kettfäden kann, wie erwähnt, grundsätzlich in drei Arten geschehen.In principle, after each weft insertion and reed stop, the upright and / or leno threads forming the leno fabric must be moved in the vertical and horizontal directions, based on the weaving plane. The weaving plane lies approximately in the horizontal direction of the respective diagram. The movement sequence of these warp threads forming the leno fabric can, as mentioned, basically be done in three ways.
Erste Art:First type:
Die Steherfäden 1 befinden sich im Unterfach und führen nur horizontale Bewegungen parallel zur Webebene aus, während die Dreherfäden 2 vertikal in das Ober- und Unterfach bewegt werden. Demgemäß bewegen sich die Führungsmittel für die Steherfäden 1 lediglich parallel zur Webebene, während die Führungsmittel für die Dreherfäden 2 quer zur Webebene eine auf- und abgehende Bewegung ausführen.The upright threads 1 are located in the lower compartment and only carry out horizontal movements parallel to the weaving plane, while the leno threads 2 are moved vertically into the upper and lower compartments. Accordingly, the guide means for the upright threads 1 only move parallel to the weaving plane, while the guiding means for the leno threads 2 execute an up and down movement transversely to the weaving plane.
Der Schussfadeneintrag geschieht bei den Schritten 1 und 4, d.h. in dem Zeitintervall, in dem jeweils ein Webfach ausgebildet ist. Der Webblattanschlag in den Schritten 2 und 5 erfolgt während die Steherfäden 1 ihre Lage in horizontaler Richtung, d.h. parallel zur Webebene ändern.The weft thread entry occurs in steps 1 and 4, i.e. in the time interval in which a shed is formed. The reed stop in steps 2 and 5 takes place while the upright threads 1 are in their position in the horizontal direction, i.e. change parallel to the web level.
Zweite Art:Second type:
Die Steherfäden 1 befinden sich im Unterfach und fuliren keine horizontale, d.h. parallel zu der Webebene gerichtete Bewegung aus. Sie behalten dauernd ihre Lage bei. Die Dreherfäden 2 führen sowohl eine horizontale als auch eine vertikale Bewegung aus. Demgemäß sind die Führungsmittel für die Steherfäden 1 ortsfest, während die Führungsmittel für die Dreherfaden 2 eine Bewegung sowohl parallel zur Webebene als auch quer zu dieser ausführen.The upright threads 1 are located in the lower compartment and do not fill horizontally, i.e. movement parallel to the weaving plane. They keep their position constantly. The leno threads 2 perform both a horizontal and a vertical movement. Accordingly, the guide means for the upright threads 1 are stationary, while the guide means for the leno threads 2 execute a movement both parallel to the weaving plane and transversely to the same.
Der Schussfadeneintrag erfolgt wiederum in den Zeitintervallen, in denen ein Webfach ausgebildet ist, d.h. bei den Schritten 1 und 4. Der Webblattanschlag geschieht in den Schritten 2 und 5, während die Dreherfaden ihre Lage in horizontaler Richtung, d.h. parallel zur Webebene ändern.The weft insertion is again carried out in the time intervals in which a shed is formed, i.e. in steps 1 and 4. The reed stop takes place in steps 2 and 5, while the leno thread is positioned horizontally, i.e. change parallel to the web level.
Dritte Art: Die Steherfäden 1 und die Dreherfäden 2 führen beide eine Bewegung in vertikaler Richtung, d.h. quer zur Webebene aus, wobei die Steher- oder Dreherfäden 1 bzw. 2 ungefähr bei ■ Fachschluss zusätzlich horizontal, d.h. parallel zur Webebene bewegt werden. Demgemäß sind die Führungsmittel sowohl für die Steherfäden 1 als auch für die Dreherfäden 2 entsprechend diesem Bewegungsablauf zu bewegen.Third type: The core threads 1 and the leno threads 2 are both perform a movement in the vertical direction, ie transversely of the weaving plane, said Steher- or leno threads 1 and 2 are moved at approximately ■ shed closing addition horizontally ie parallel to the weaving plane. Accordingly, the guide means for both the upright threads 1 and for the leno threads 2 are to be moved in accordance with this movement sequence.
Der Schussfadeneintrag und der Webblattanschlag erfolgt wieder bei den Schritten 1 und 4 bzw. 2 und 5.The weft thread entry and the reed stop are again carried out in steps 1 and 4 or 2 and 5.
Die in den Figuren 3, 8 und 9 schematisch dargestellte erfindungsgemäße Webmaschine verwendet einen Bewegungsablauf der vorgenannten ersten Art der Dreherbindung. Sie weist einen Kettbaum 3 auf, von dem über einen Streichbaum 4 die Steherfäden 1 und Dreherfäden 2 enthaltende Webkette 5 abgelassen wird. Ausgehend von dem bei 6 angedeuteten Punkt verlaufen die Steherfäden 1 und die Dreherfäden 2 durch zwei Nadelriete 7, 8 die auch als Lamellenriete ausgebildet sein können und durch ein an sich bekanntes, bei 9 angedeutetesThe loom according to the invention shown schematically in FIGS. 3, 8 and 9 uses a movement sequence of the aforementioned first type of leno weave. It has a warp beam 3 from which the warp threads 1 containing the upright threads 1 and leno threads 2 are let down via a match beam 4. Starting from the point indicated at 6, the upright threads 1 and the leno threads 2 run through two needle reeds 7, 8, which can also be designed as lamella reeds, and through a known one, indicated at 9
Webblatt, das auf einer Weblade 10 befestigt ist, zu einem ortsfesten Gewebetisch 11, an dessen dem Webblatt 9 zugewandter Kante - bei 12 - der Blatt- oder Schussfadenanschlag erfolgt. Der Schussfadeneintrag erfolgt bei der dargestellten Webmaschine, die als sogenannten Luftdüsenwebmaschine ausgebildet ist, auf pneumatischem Wege in an sich bekannter Weise. Die Schussfadeneintragsmittel sind durch an der Weblade 10 im Abstand angeordnete mit Druckluf beaufschlagte Stafettendüsen 13 angedeutet.Reed, which is attached to a sley 10, to a stationary fabric table 11, on the edge of which faces the reed 9 - at 12 - the leaf or weft stop. In the weaving machine shown, which is designed as a so-called air-jet weaving machine, the weft thread is introduced pneumatically in a manner known per se. The weft insertion means are indicated by relay nozzles 13, which are spaced apart on the sley 10 and pressurized with compressed air.
Von dem Gewebetisch 11 wird das erzeugte Drehergewebe 14 über eine Umlenkwalze 15 einer Einziehwalze 16 zugeleitet von der aus es durch eine Klemmstelle zwischen der Einziehwalze 16 und einer Anpresswalze 17 über zwei Umlenkwalzen 18, 19 zu dem nicht weiter dargestellten Warenbaum gelangt, auf dem es aufgewickelt wird. Die erwähnten Walzen sind in einem bei 20 ausschnittsweise angedeuteten Maschinengestell drehbar gelagert, das auch den Gewebetisch 11 trägt. Ihre zugeordneten Antriebe sind an sich bekannt und nicht weiter dargestellt. In dem Bereich zwischen dem Punkt 6 und den Nadelrieten 7, 8 verlaufen die Steher- und Dreherfäden 1 bzw. 2 durch einen Kettfadenwächter 21 , dessen auf den Kettfäden aufreitende Lamellen mit 22 bezeichnet und, ebenso wie die Steher- und Dreherfäden 1, 2, bei einem Kettfadenbruch von oben her unbehindert leicht zugänglich sind.From the fabric table 11, the leno fabric 14 that is produced is fed via a deflection roller 15 to a drawing-in roller 16, from which it passes through a nip between the drawing-in roller 16 and a pressure roller 17 via two deflection rollers 18, 19 to the material tree (not shown) on which it is wound up becomes. The rollers mentioned are rotatably mounted in a machine frame, indicated at 20 in sections, which also carries the fabric table 11. Their assigned drives are known per se and are not shown any further. In the area between the point 6 and the needle reeds 7, 8, the upright and leno threads 1 and 2 run through a warp thread monitor 21, the slats of which spread on the warp threads, designated 22 and, like the upright and leno threads 1, 2, if the warp thread breaks easily accessible from above.
Die Weblade 10 mit dem Webblatt 9 ist über Stützen 23 mit einer in dem Maschinengestell 20 drehbar gelagerten, eine oszillierende Drehbewegung ausführenden Welle, der sogenannten Webblattwelle 24 fest verbunden, um deren Drehachse sie eine dem Schussfadenanschlag dienende, hin- und hergehende Bewegung ausführt. Der Antrieb der Webblattwelle 24 ist in Fig. 7 mit seinen wesentlichen, hier interessierenden Elementen schematisch veranschaulicht. Aus der Figur 7 ist zu entnehmen, dass die Webblattwelle 24 endseitig jeweils einen Exzenterhebel 25 trägt, von denen einer dargestellt ist, der eine zugeordnete Kurvenscheibe 26 abtastet, die über ein Zahnradgetriebe 27 von einer schnelllaufenden Antriebswelle 28 angetrieben ist, deren Antrieb durch einen nicht weiter dargestellten Antriebsmotor erfolgt. Die schnelllaufende Antriebswelle 28 führt eine einsinnige, kontinuierliche Drehbewegung aus, während der Webblattwelle 24 über das aus der Kurvenscheibe 26 und dem Kurvenhebel 25 gebildete Exzentergetriebe eine oszillierende Drehbewegung erteilt wird.The sley 10 with the reed 9 is firmly connected via supports 23 to a shaft, which is rotatably mounted in the machine frame 20 and carries out an oscillating rotary movement, the so-called reed shaft 24, about the axis of rotation of which it executes a reciprocating movement serving the weft stop. The drive of the reed shaft 24 is schematically illustrated in FIG. 7 with its essential elements that are of interest here. It can be seen from FIG. 7 that the reed shaft 24 carries an eccentric lever 25 at the end, one of which is shown, which scans an associated cam disk 26, which is driven by a high-speed drive shaft 28 via a gear transmission 27, the drive of which is not by one drive motor shown further takes place. The high-speed drive shaft 28 performs a unidirectional, continuous rotary movement, while the reed shaft 24 is given an oscillating rotary movement via the eccentric gear formed by the cam disk 26 and the cam lever 25.
Der grundsätzliche Aufbau der Nadelriete 7, 8 ist insbesondere aus den Figuren 4 bis 6 zu ersehen, in denen das Nadelriet 7 dargestellt ist. Das Nadelriet 7 weist eine Nadelbarre 29 und einen damit verbundenen Rahmen 30 auf. Es erstreckt sich über die Webbreite und kann in einzelne Abschnitte unterteilt sein, die an der Weblade 10 befestigt sind. Der Rahmen 30 umschließt in gleichmäßigen Abständen nebeneinander angeordnete Lamellen 31 zwischen denen jeweils mittig lamellenartig ausgebildete, flache Nadeln 32 angeordnet sind, die einenends in der Nadelbarre 29 verankert sind und andernends jeweils ein Fadenauge 33 aufweisen. Das Fadenauge 33 ist in einem Endbereich 34 der jeweiligen Nadel 32 ausgebildet, der gegenüber dem anschließenden Nadelschaft 35 um einen kleinen Winkel (10° - 45°) so weit verschränkt ist, dass sich in Kettfadenrichtung eine wirksame lichte Weite des Fadenauges 33 ergibt, die einen im Wesentlichen berührungslosen Durchgang eines Fadens ermöglicht. Die Abstände zwischen den flachen Nadeln 32 und den diesem benachbarten parallel zu ihnen ausgerichteten Lamellen 31 sind so gewählt, dass Steher- bzw. Dreherfäden 1, 2 unbehindert zwischen den Nadelschäften 35 und den benachbarten Lamellen 31 durchlaufen können. Die Lamellen 31 und die Nadeln 32 sind durch durchgehende Zuganker mit dazwischen gelegten Abstandsringen7a(Fig. 4) auf genauem gegenseitigem Abstand gehalten. Das Nadelriet 8 unterscheidet sich von dem beschriebenen Nadelriet 7 im Wesentlichen lediglich dadurch, dass seine Fadenaugen 33 nahe der Nadelbarre 29 angeordnet sind, während sie bei dem Nadelriet 8 sich in der Nähe des oberen Querschenkels 30a des Rahmens 30 befinden, wie dies insbesondere aus den Figuren 8, 9 zu ersehen ist.The basic structure of the needle reed 7, 8 can be seen in particular from FIGS. 4 to 6, in which the needle reed 7 is shown. The needle reed 7 has a needle bar 29 and a frame 30 connected to it. It extends over the weaving width and can be divided into individual sections which are attached to the weaving sley 10. The frame 30 encloses, at regular intervals, lamellae 31 which are arranged next to one another and between which lamellar flat needles 32 are arranged, which are anchored in the needle bar 29 at one end and each have a thread eye 33 at the other end. The thread eye 33 is formed in an end region 34 of the respective needle 32, which is interlaced by a small angle (10 ° -45 °) with respect to the subsequent needle shaft 35 to such an extent that there is an effective clear width of the thread eye 33 in the warp thread direction, which enables a substantially contactless passage of a thread. The distances between the flat needles 32 and the adjacent slats 31 aligned parallel to them are selected such that upright or leno threads 1, 2 can pass freely between the needle shafts 35 and the adjacent slats 31. The lamellae 31 and the needles 32 are kept at a precise mutual distance by continuous tie rods with spacer rings 7a (FIG. 4) interposed therebetween. The needle reed 8 differs from the needle reed 7 described essentially only in that its thread eyes 33 are arranged near the needle bar 29, while in the needle reed 8 they are located in the vicinity of the upper transverse leg 30a of the frame 30, as can be seen in particular in FIGS Figures 8, 9 can be seen.
Das Nadelriet 7 ist mit seiner Nadelbarre 29 an über die Webbreite verteilt angeordneten Nadelrietstützen 36 befestigt, die radial vorragend drehfest auf eine Nadelrietwelle 37 aufgeklemmt sind, welche in dem Maschinengestell 20 parallel zu der Webblattwelle 24 verlaufend drehbar gelagert ist. Die Nadelrietwelle 37 ist mit der Webblattwelle 24 formschlüssig getrieblich gekoppelt. Bei der in den Figuren 3, 8 und 9 dargestelltenThe needle reed 7 is fastened with its needle bar 29 to needle reed supports 36 which are distributed over the weaving width and which are clamped in a radially projecting manner on a needle reed shaft 37 which is rotatably mounted in the machine frame 20 parallel to the reed shaft 24. The needle shaft 37 is positively coupled to the reed shaft 24. The one shown in FIGS. 3, 8 and 9
Ausfuhruiigsform ist diese getriebliche Kopplung durch einen Zahnriementrieb verwirklicht, der einen Zahnriemen 38 und je einer auf die Webblattwelle 24 und die Nadelrietwelle 37 drehfest aufgesetzten Zahnriemenscheibe 39 bzw. 40 besteht. Die beiden Zahnriemenscheiben 39, 40 sind in Fig. 7 nicht sichtbar, worauf der Ordnung halber hingewiesen sei. Wegen der getrieblichen Kopplung zwischen der Webblattwelle 24 und der Nadelrietwelle 37 führt das Nadelriet 7 eine Schwenkbewegung um die Achse 41 der Nadelrietwelle 37 zwischen zwei in den Figuren 8, 9 veranschaulichten Grenzstellungen aus, wobei diese Schwenkbewegung mit der dem Schussanschlag dienenden Hin- und Herbewegung des Webblatts 9 zwangsläufig synchronisiert ist, wie dies im Einzelnen noch erläutert werden wird.In the embodiment, this gear coupling is realized by a toothed belt drive, which consists of a toothed belt 38 and one toothed belt pulley 39 or 40, which is attached to the reed shaft 24 and the needle reed shaft 37 in a rotationally fixed manner. The two toothed belt pulleys 39, 40 are not visible in FIG. 7, which is pointed out for the sake of order. Because of the gear coupling between the reed shaft 24 and the needle reed shaft 37, the needle reed 7 performs a swiveling movement about the axis 41 of the needle reed shaft 37 between two limit positions illustrated in FIGS. 8, 9, this swiveling movement with the back and forth movement of the firing stroke Webblatt 9 is necessarily synchronized, as will be explained in more detail.
Das dem Webblatt 9 kettfadenseitig unmittelbar benachbarte, andere Nadelriet 8 ist quer zu der in Fig. 3 bei 42 angedeuteten, im Wesentlichen horizontal verlaufenden Webebene ausgerichtet, in dem Maschinengestell 20 horizontal hin- und herbeweglich gelagert. Die zugehörigen Seitenfuhrungen sind in den Figuren nicht weiter dargestellt.The other needle reed 8, which is immediately adjacent to the reed 9 on the warp thread side, is oriented transversely to the essentially horizontal weaving plane indicated at 42 in FIG. 3, and is horizontally and reciprocally supported in the machine frame 20. The associated side guides are not shown in the figures.
Wie insbesondere aus den Figuren 3, 10 zu ersehen, ist an dem Nadelriet 8 im Bereiche seiner Nadelbarre 29 wenigstens ein Lagerbock 43 befestigt, an dem es über eine Koppelstange 44 an einem ortsfesten zweiten Lagerbock 45 gelenkig gelagert ist. Die zueinander parallelen Gelenkachsen der Lagerböcke 43, 45 sind mit 46, 47 bezeichnet. Die Koppelstange ist zweiteilig mit einem Teil 44a und einem darin eingesteckten Teil 44b ausgebildet, so dass die Länge der Koppelstange 44 nach Lösen und Wiederfestziehen von Stellschrauben 48 bedarfsgemäß verändert werden kann.As can be seen in particular from FIGS. 3, 10, at least one bearing block 43 is fastened to the needle reed 8 in the region of its needle bar 29, on which it is articulated via a coupling rod 44 on a stationary second bearing block 45. The mutually parallel joint axes of the bearing blocks 43, 45 are designated 46, 47. The coupling rod is formed in two parts with a part 44a and a part 44b inserted therein, so that the length of the coupling rod 44 after loosening and re-tightening the set screws 48 as required can be changed.
Auf das z.B. einen zylindrischen Querschnitt aufweisende Teil 44a der Koppelstange 44 ist eine Hülse 49 längsverschieblich aufgesetzt, die über Stellschrauben 50 in der jeweils eingestellten Lage fixierbar ist und die ein Lagerteil 51 trägt an dem eine Pleuelstange 52 eines Kurbelgetriebes 53 angelenkt ist, dessen Exzenter mit 54 bezeichnet ist. Der Exzenter 54 sitzt drehfest auf einer Antriebswelle 55, die mit einem Antriebsrad in Form eines Kronenrades 56 drehfest verbunden ist, welches über ein Ritzel 57 von der schnelllaufenden Welle 28 des in Figur 7 dargestellten Webladenantriebs angetrieben ist. Das Ritzel 57 ist in Fig. 7 nicht sichtbar.For example a part 44a of the coupling rod 44 having a cylindrical cross-section, a sleeve 49 is slid longitudinally, which can be fixed in the respectively set position by means of set screws 50 and which carries a bearing part 51 to which a connecting rod 52 of a crank mechanism 53 is articulated, the eccentric of which is designated by 54 , The eccentric 54 is non-rotatably seated on a drive shaft 55, which is non-rotatably connected to a drive wheel in the form of a crown wheel 56, which is driven via a pinion 57 by the high-speed shaft 28 of the weaving shutter drive shown in FIG. The pinion 57 is not visible in FIG. 7.
Die Pleuelstange 52 ist zweiteilig ausgebildet. Ihre beiden ineinander gesteckten Teile können nach Lösen von Feststellschrauben 58 auf die jeweils gewünschte Länge der Pleuelstange 52 eingestellt werden. Über das Kurbelgetriebe 53 wird bei umlaufender Welle 28 der Koppelstange 44 eine Schwenkbewegung um ihre ortsfeste Schwenkachse 47 erteilt, so dass das mit ihr gekoppelte Nadelriet 8 eine entsprechende horizontale hin- und hergehende Bewegung ausführt. Der Hub dieser hin- und hergehenden Linearbewegung kann dadurch verändert werden, dass der Abstand der Hülse 49 von der gestellfesten Schwenkachse 47 auf der Koppelstange 44 entsprechend verstellt wird. Diese Verstellung ist nach Lösen der Stellschrauben 48, 50 und 58 ohne Weiteres möglich. Die zweigeteilte Koppelstange 44 erlaubt es außerdem die Höhe des Nadelriets 48 über ihrer Lagerstelle bei 45 und damit bezüglich der Webebene 42 (Fig. 3) zweckentsprechend einzustellen.The connecting rod 52 is formed in two parts. Your two nested parts can be adjusted to the desired length of the connecting rod 52 after loosening the locking screws 58. When the shaft 28 rotates, the coupling rod 44 is given a pivoting movement about its fixed pivot axis 47 via the crank mechanism 53, so that the needle reed 8 coupled to it executes a corresponding horizontal reciprocating movement. The stroke of this reciprocating linear movement can be changed in that the distance of the sleeve 49 from the pivot axis 47 fixed to the frame on the coupling rod 44 is adjusted accordingly. This adjustment is easily possible after loosening the set screws 48, 50 and 58. The two-part coupling rod 44 also allows the height of the needle reed 48 above its bearing point at 45 and thus with respect to the weaving plane 42 (FIG. 3) to be set appropriately.
Während bei der beschriebenen Ausführungsform nach Fig. 10 der Anrieb des Nadelriets 8 unmittelbar von der schnelllaufenden Hauptwelle 28 des Webladenantriebs abgeleitet ist, ist in Fig. 11 eine Ausführungsform dargestellt, bei der die hin- und hergehende Bewegung des Nadelriets 8 mit einem anderen mechanischen Antriebskonzept realisiert ist. Bei dieser Ausfuhrungsform ist das Kurbelgetriebe 53 mit einer eigenen Antriebsquelle, bspw. in Gestalt eines Elektromotors 59 gekoppelt, der bei 60 ortsfest abgestützt ist. Grundsätzlich können pneumatische, hydraulische und elektrische Antriebsquellen verwendet werden. Die Antriebsquelle 59 ist mit dem Webladenantrieb und mit den Schussfadeneintragsmitteln so synchronisiert, dass eine volle Umdrehung des Kurbelantriebsexzenters 54 zwei Schüssen bzw. Webzyklen entspricht. In gleicher Weise ist auch die Getriebeübersetzung zwischen dem Antriebskronenrad 56 und dem Ritzel 57 bei der Ausführungsform nach Fig. 10 dimensioniert. Das bedeutet, dass die Pleuelstange 52 das Nadelriet 8 nach dem ersten Schuss horizontal nach rechts und nach dem zweiten Schuss horizontal nach links zieht (bezogen auf Fig. 10/11), wenn der Bindungsrapport für das Drehegewebe aus zwei Schüssen besteht. Im Übrigen sind in den Figuren 10/11 für gleiche Teile gleiche Bezugszeichen verwendet, so dass sich eine nochmalige Erläuterung insoweit erübrigt.While in the described embodiment according to FIG. 10 the drive of the needle reed 8 is derived directly from the high-speed main shaft 28 of the shutter drive, an embodiment is shown in FIG. 11 in which the reciprocating movement of the needle reed 8 with a different mechanical drive concept is realized. In this embodiment, the crank mechanism 53 is coupled to its own drive source, for example in the form of an electric motor 59, which is fixedly supported at 60. In principle, pneumatic, hydraulic and electrical drive sources can be used. The drive source 59 is synchronized with the weaving shutter drive and with the weft insertion means in such a way that a full revolution of the crank drive eccentric 54 two shots or Corresponds to web cycles. The gear ratio between the drive crown gear 56 and the pinion 57 in the embodiment according to FIG. 10 is dimensioned in the same way. This means that the connecting rod 52 pulls the needle reed 8 horizontally to the right after the first shot and horizontally to the left after the second shot (based on FIG. 10/11) if the weave weave repeat consists of two shots. For the rest, the same reference numerals are used in FIGS. 10/11 for the same parts, so that a further explanation is not necessary.
Die beschriebene Webmaschine arbeitet wie folgt, wobei insbesondere auf die die Webfachbildung veranschaulichenden Figuren 8, 9 Bezug genommen wird.The weaving machine described operates as follows, with particular reference being made to FIGS. 8, 9 illustrating the weaving shed formation.
Die Steherfaden 1 verlaufen durch die Fadenaugen 33 der Nadeln 32 des dem Webblatt 9 kettfadenseitig unmittelbar benachbarten Nadelriets 8, während die Dreherfäden 2 durch die Fadenaugen 33 der Nadeln 32 des kettseitig unmittelbar vor dem Nadelriet 8 liegenden Nadelriets 7 gezogen sind und das Nadelriet 8 in den Zwischenräumen zwischen den Nadeln 32 und den diesen benachbarten Lamellen 31 passieren. In ähnlicher Weise verlaufen die Steherfäden 1 durch die Zwischenräume zwischen den Nadeln 32 und den Lamellen 31 des Nadelriets 7. Die Steherfäden 1 werden somit durch die Bewegungen des Nadelriets 8 mitbewegt, während die Dreherfäden 2 die Bewegungen des Nadelriets 7 mitmachen. Die Hübe dieser Bewegungen müssen größer sein als die lichte Weite der Fadenaugen 33, damit eine einwändfreie Führung der Fäden gewährleistet ist. Die Nadelriete 8, 7 sind somit die Führungsmittel für die Steherfäden 1 bzw. die Dreherfäden 2.The upright thread 1 runs through the thread eyes 33 of the needles 32 of the needle reed 8 immediately adjacent to the reed 9 on the warp thread side, while the leno threads 2 are pulled through the thread eyes 33 of the needles 32 of the needle reed 7 lying immediately in front of the needle reed 8 and the needle reed 8 into the Pass gaps between the needles 32 and the slats 31 adjacent to them. In a similar manner, the upright threads 1 run through the spaces between the needles 32 and the lamellae 31 of the needle reed 7. The upright threads 1 are thus moved along by the movements of the needle reed 8, while the leno threads 2 follow the movements of the needle reed 7. The strokes of these movements must be greater than the clear width of the thread eyes 33, so that the threads can be guided without any problems. The needle reeds 8, 7 are thus the guide means for the upright threads 1 and the leno threads 2.
In Fig. 8 ist der Zustand dargestellt, bei dem sich das Webblatt 9 in der Blatt- oder Schussfadenanschlagstellung befindet. Das über die Webblattwelle 24 und die Nadelrietwelle 37 formschlüssig mit dem Webblatt 9 synchronisierte Nadelriet 7 nimmt die Stellung nach Fig. 8 ein, in der es etwa rechtwinklig zur Webebene 42 ausgerichtet in geringem Abstand parallel zu dem anderen Nadelriet 8 der Steherfäden 1 liegt. In dieser Stellung hält das Nadelriet 7 die Dreherfäden 2 in dem geeigneten Bereich des Unterfaches (vgl. Fig. 8).8 shows the state in which the reed 9 is in the leaf or weft stop position. The needle reed 7, which is positively synchronized with the reed 9 via the reed shaft 24 and the needle reed shaft 37, assumes the position according to FIG. 8, in which it is oriented approximately at right angles to the weaving plane 42 and is at a short distance parallel to the other needle reed 8 of the upright threads 1. In this position, the needle reed 7 holds the leno threads 2 in the appropriate area of the lower compartment (cf. FIG. 8).
Bewegt sich nun das Webblatt 9 in seine von dem Gewebetisch 11 entfernte hintere Stellung nach Fig. 9, so wird wegen der zwangsläufigen Kopplung mit der Webblattwelle 24 das Nadelriet 7 um die Schwenkachse 41 im Gegenuhrzeigersinn nach oben geschwenkt, wodurch die Dreherfäden 2 nach oben bewegt werden und das Webfach geöffnet wird. Tritt dabei im Bewegungsablauf der Weblade 9 ein Stillstand ein, wenn die Weblade 9 sich in ihrer hintersten Stellung (Fig. 9) befindet, so ergibt sich auch ein zeitlich gleich großer Webfachstillstand. Das Ergebnis davon ist ein optimal großer Schussfadeneintragswinkel des Webfachs.Now the reed 9 moves into its rear position removed from the fabric table 11 9, because of the inevitable coupling with the reed shaft 24, the needle reed 7 is pivoted upward about the pivot axis 41 in the counterclockwise direction, as a result of which the leno threads 2 are moved upward and the shed is opened. If there is a standstill in the movement sequence of the sley 9 when the sley 9 is in its rearmost position (FIG. 9), the shed is stopped at the same time. The result of this is an optimally large weft insertion angle of the shed.
Zwischen den beiden Grenzstellungen de Webblatts 9 und des Nadelriets 7, wie sie in den Figuren 8, 9 dargestellt sind, erfolgt die in Abbildung 2 oben unter „erste Art" erläuterte Bewegung der Steher- und Dreherfäden 1 bzw. 2:Between the two limit positions of the reed 9 and the needle reed 7, as shown in FIGS. 8, 9, there is the movement of the upright and leno threads 1 and 2, which is explained in FIG. 2 above under “first type”:
Nach dem in dem Zustand nach Fig. 9 erfolgten Schussfadeneintrag bewegt sich die Weblade 9, bezogen auf Fig. 9 nach rechts bis sie die Schussfadenanschlagstellung nach Fig. 8 erreicht. Dabei wird der eingetragene Schussfaden angeschlagen. Gleichzeitig geht das die Dreherfäden 2 führende Nadelriet 7 nach unten, wobei die Dreherfäden 2 in das Unterfach überführt werden, wie dies in Fig. 8 dargestellt ist. Gleichzeitig wird das andere Nadelriet 8 parallel zur Webebene 42 verschoben, so dass die Steherfäden 1 bezüglich der Dreherfäden 2 seitlich versetzt werden. Anschließend bewegt sich die Weblade 9 wieder aus der Anschlagstellung nach hinten, während das den Dreherfäden 2 zugeordnete Nadelriet 7 synchron nach oben geht bis der Zustand nach Fig. 9 ereeicht ist, in dem ein neuer Schussfadeneintrag erfolgt.After the weft thread has been inserted in the state according to FIG. 9, the sley 9 moves relative to FIG. 9 to the right until it reaches the weft stop position according to FIG. 8. The registered weft thread is struck. At the same time, the needle reeds 7 guiding the leno threads 2 go down, the leno threads 2 being transferred into the lower compartment, as shown in FIG. 8. At the same time, the other needle reed 8 is moved parallel to the weaving plane 42, so that the upright threads 1 are laterally offset with respect to the leno threads 2. Subsequently, the sley 9 moves back again from the stop position, while the needle reed 7 assigned to the leno threads 2 goes up synchronously until the state according to FIG. 9 is reached in which a new weft thread is inserted.
Da die Fadenaugen 33 der Nadelriete 7, 8 in der in Figur 8 veranschaulichten Geschlossen-Fach- Stellung nahe beieinander liegen, erfolgt der Seitenwechsel der Steherfäden 1 bezüglich der Dreherfäden 2 sehr präzise. In der Offen-Fach-Stellung nach Fig. 9 ist dagegen das den Dreherfäden 2 zugeordnete Nadelriet 7 nach hinten und oben geschwenkt so dass der ganze Bereich einschl. der zwischen den beiden Nadelrieten 7, 8 liegenden Kettfadenbereiche für eine Ketfadenbruchbehebung gut zugänglich ist.Since the thread eyes 33 of the needle reeds 7, 8 are close to each other in the closed shed position illustrated in FIG. 8, the change of the upright threads 1 with respect to the leno threads 2 takes place very precisely. In the open compartment position according to FIG. 9, on the other hand, the needle reeds 7 assigned to the leno threads 2 are pivoted backwards and upwards, so that the entire area including the warp thread areas lying between the two needle reeds 7, 8 is easily accessible for repairing the warp threads.
Abhängig von der Dicke, der Konstruktion und dem Material der Steher- und der Dreherfäden 1, 2 sowie der Art der zu erzeugenden Dreherbindung kann, wie bereits erläutert, der Hub des die Steherfäden 1 fuhrenden Nadelriets 8 zweckentsprechend eingestellt werden. Die mechanische Kopplung der Nadelrietwelle 37 mit der Webblattwelle 24 kann abweichend von der Ausfuhrungsform nach Fig. 3 auch auf andere Weise geschehen.Depending on the thickness, the construction and the material of the upright and leno threads 1, 2 as well as the type of leno weave to be produced, the stroke of the needle reeds 8 which guide the upright threads 1 can be set appropriately, as already explained. The mechanical coupling of the needle reed shaft 37 with the reed shaft 24 can also be done differently from the embodiment according to FIG. 3.
Eine weitere Ausführungsform ist in Fig. 12 veranschaulicht, in der mit der Webmaschine nach Fig. 3 gleiche Teile mit gleichen Bezugszeichen bezeichnet und nicht nochmals erläutert sind. Bei dieser Ausführungsfonn ist zwischen der Webblattwelle 24 und der Nadelrietwelle 37 ein Koppelgetriebe vorgesehen, das aus wenigstens einer an einer Webladenstütze 23 angelenkten Stange 61 und einem drehfest auf die Nadelrietwelle 37 aufgeklemmten Hebelarm 62 besteht, an den die Stange 61 anderenends gelenkig angeschlossen ist. Durch entsprechende Änderung der wirksamen Länge des Hebelarmes 62 - bspw. indem der Anlenkpunkt der Stange 61 radial verschoben wird - kann die Hubhöhe des Nadelriets 7 eingestellt werden. Die Antriebsmittel des den Steherfäden 1 zugeordneten anderen Nadelriets 8 sind gleich wie bei der Ausführungsform nach Fig. 3 gestaltet.A further embodiment is illustrated in FIG. 12, in which the same parts are designated by the same reference numerals with the weaving machine according to FIG. 3 and are not explained again. In this embodiment, a coupling gear is provided between the reed shaft 24 and the needle reed shaft 37, which consists of at least one rod 61 articulated on a shutter support 23 and a lever arm 62 rotatably clamped on the needle reed shaft 37, to which the rod 61 is articulated at the other end. The lifting height of the needle reed 7 can be adjusted by correspondingly changing the effective length of the lever arm 62 - for example by radially displacing the articulation point of the rod 61. The drive means of the other needle reeds 8 assigned to the upright threads 1 are designed in the same way as in the embodiment according to FIG. 3.
Die in Fig. 13 schematisch dargestellte abgewandelte erfindungsgemäße Webmaschine ist dazu eingerichtet die Dreherbindung mit einem Bewegungsablauf der Steher- und Dreherfäden 1, 2 herzustellen, der dem in Fig. 2 in der Mitte veranschaulichten Diagramm „zweite Art" entspricht. Mit der Webmaschine nach Fig. 3 gleiche Teile sind wieder mit gleichen Bezugszeichen versehen und nicht weiter erläutert.The modified loom according to the invention shown schematically in FIG. 13 is set up to produce the leno weave with a movement sequence of the upright and leno threads 1, 2, which corresponds to the diagram “second type” illustrated in the middle in FIG. 2. With the loom according to FIG 3 The same parts are again provided with the same reference symbols and are not further explained.
Bei dieser Ausführungsform ist das dem Webblatt 9 kettseitig unmittelbar benachbarte, den Steherfäden 1 zugeordnete Nadelriet 8 in dem Maschinengestell 20 ortsfest gehaltert. Die durch die Fadenaugen 33 dieses Nadelriets 8 verlaufenden Steherfäden 1 nehmen deshalb während des Webvorgangs immer die gleiche Lage ein.In this embodiment, the needle reed 8, which is immediately adjacent to the reed 9 on the warp side and is assigned to the upholstery threads 1, is held stationary in the machine frame 20. The upright threads 1 running through the thread eyes 33 of this needle reed 8 therefore always assume the same position during the weaving process.
Das die Dreherfäden 2 führende andere Nadelriet 7 ist über die Nadelrietstütze 36 wiederum auf der Nadelrietwelle 37 befestigt, die in diesem Falle in dem Maschinengestell aber nicht nur drehbar sondern auch axial verschieblich gelagert ist. Ähnlich wie bei Ausführungsform nach Fig. 12 wird die im Wesentlichen quer zu der Webebene 42 verlaufende, vertikale Schwenkbewegung des Nadelriets 7 durch die formschlüssige getriebliche Kopplung derThe other needle reeds 7 guiding the leno threads 2 are in turn fastened on the needle reed support 36 on the needle reed shaft 37, which in this case is not only rotatably but also axially displaceably mounted in the machine frame. Similar to the embodiment according to FIG. 12, the vertical pivoting movement of the needle reed 7, which runs essentially transversely to the weaving plane 42, is achieved by the form-fitting gear coupling of the
Nadelrietwelle 37 mit der Webblattwelle 24 erzeugt. Diese Kopplung erfolgt über die Stange 61 und den Hebelarm 62. Zur Erzeugung der parallel zur Webebene 42 erfolgenden, hin- und hergehenden horizontalen Bewegung des Nadelrietes 7 dient ein Kurvengetriebe 63, dessen Einzelheiten insbesondere aus Fig. 15 zu entnehmen sind. Das Kurvengetriebe 63 ist im Grundsatz gleich wie das Kurvengetriebe 53 nach Fig. 10 aufgebaut. Es weist ein Antriebskronenrad 64 auf, das mit einem Antriebsexzenter 65 drehfest verbunden ist, auf dem eine Pleuelstange 66 gelagert ist, die über eine Verbindungslasche 67 an einem die Nadelrietwelle 37 umschließenden und an dieser festgeklemmten Lagerteil 68 axial unverschieblich angelenkt ist. Das Antriebskronenrad 64 wird von einem Ritzel 69 angetrieben, das drehfest auf der Hauptantriebswelle 28 der Webmaschine sitzt. Die wirksame Länge der Pleuelstange 66 ist über Stellschrauben 70 veränderlich, um damit eine Veränderung der Hublänge des Nadelriets 7 zu ermöglichen, die dadurch zustande gebracht wird, dass das Lagerteil 68 auf der Antriebswelle 37 zweckentsprechend verschoben wird.Needle reed shaft 37 generated with the reed shaft 24. This coupling takes place via the rod 61 and the lever arm 62. A cam mechanism 63 serves to generate the reciprocating horizontal movement of the needle reed 7 parallel to the weaving plane 42, the details of which can be found in particular in FIG. 15. The cam mechanism 63 is basically constructed in the same way as the cam mechanism 53 according to FIG. 10. It has a drive crown wheel 64 which is connected in a rotationally fixed manner to a drive eccentric 65, on which a connecting rod 66 is mounted, which is articulated axially immovably via a connecting bracket 67 to a bearing part 68 which surrounds the needle shaft 37 and is clamped thereon. The drive crown gear 64 is driven by a pinion 69, which is non-rotatably seated on the main drive shaft 28 of the weaving machine. The effective length of the connecting rod 66 can be changed by means of adjusting screws 70 in order to enable a change in the stroke length of the needle reed 7, which is brought about by the bearing part 68 being displaced on the drive shaft 37 accordingly.
Die Übersetzungen des Kurvengetriebes 63 und des aus der Stange 61 und dem Hebelarm 62 bestehenden Koppelgetriebes sind so gewählt, dass die beiden Nadelriete 7, 8 den in Fig. 2, mittleres Diagramm, unter „zweite Art" dargestellten Bewegungsablauf ausführen, zu dem anhand der vorausgegangenen Erläuterungen weitere Ausführungen nicht erforderlich erscheinen.The translations of the cam mechanism 63 and the coupling mechanism consisting of the rod 61 and the lever arm 62 are selected such that the two needle reeds 7, 8 carry out the movement sequence shown in FIG. 2, middle diagram, under “second type”, based on the previous explanations further explanations do not appear to be necessary.
In Fig. 14 schließlich ist eine weitere abgewandelte Ausführungsform der erfindungsgemäßen Webmaschine dargestellt, die dazu eingerichtet ist, den Bewegungsablauf ähnlich dem unteren Diagramm nach Fig. 2, d.h. auf die „dritte Art" durchzuführen. Mit der Webmaschine nach Fig. 3 gleiche Teile sind wiederum mit gleichen Bezugszeichen versehen und nicht weiter erläutert.Finally, FIG. 14 shows a further modified embodiment of the weaving machine according to the invention, which is set up to simulate the movement sequence similar to the lower diagram according to FIG. in the “third way”. Parts that are the same with the weaving machine according to FIG. 3 are again provided with the same reference numerals and are not further explained.
Bei dieser Ausführungsform ist das die Dreherfäden 2 führende Nadelriet 7, gleich wie bei der Ausführungsform nach Fig. 13, über das aus der Stange 61 und dem Hebelarm 62 bestehende Koppelgetriebe mit wenigstens einer Webladenstütze 23 und damit mit der Webblattwelle 24 getrieblich starr gekoppelt. Das Nadelriet 7 sitzt wiederum auf den Nadelrietstützen 36, die auf der Nadelrietwelle 37 fest angeschraubt sind, so dass ihm im Takt der Hin- und Herbewegung des Webblatts 9 eine darauf abgestimmte, auf- und abgehende Bewegung erteilt wird, die eine entsprechende quer zu der Webebene 42 gerichtete Auf- und Abbewegung der Dreherfäden 2 ergibt. Außerdem ist die Nadelrietwelle 37 mit dem Kurbelgetriebe 63 nach Fig. 15 in der dort beschriebenen Weise gekuppelt. Das Kurbelgetriebe 63 erteilt der Nadelrietwelle 37 und damit dem Nadelriet 7 die parallel zur Webebene 42 erfolgende, horizontale hin- und hergehende Bewegung, die zum seitlichen Versatz der Dreherfäden 2 gegenüber den Steherfäden 1 erforderlich ist.In this embodiment, the needle reeds 7 guiding the leno threads 2, in the same way as in the embodiment according to FIG. 13, are rigidly coupled via the coupling gear consisting of the rod 61 and the lever arm 62 to at least one weaving support 23 and thus to the reed shaft 24. The needle reed 7 in turn sits on the needle reed supports 36, which are screwed tightly onto the needle reed shaft 37, so that it is given a coordinated, up and down movement in time with the reciprocating movement of the reed 9, which corresponds to a corresponding transverse to the Weaving plane 42 directed up and down movement of the leno threads 2 results. In addition, the needle shaft 37 is coupled to the crank mechanism 63 according to FIG. 15 in the manner described there. The crank mechanism 63 gives the needle reed shaft 37 and thus the needle reed 7 the horizontal reciprocating movement that takes place parallel to the weaving plane 42 and is required for the lateral displacement of the leno threads 2 with respect to the upright threads 1.
Das die Steherfäden 1 führende Nadelriet 8 ist an armartigen Nadelrietstützen 71 befestigt, die auf einer zweiten zugeordneten Nadelrietwelle 72 festgeschraubt sind, die in dem Maschinengestell 20 drehbar gelagert ist. Mit der Nadelrietwelle 72 oder einer Nadelrietstütze 71 ist ein Radialarm 73 verbunden, an dem eine Koppelstange 74 angelenkt ist, die an ihrem anderen Ende an der gleichen Gelenkstelle wie die Stange 61 gelenkig mit der Webladenstütze 23 verbunden ist.The needle reeds 8 guiding the upright threads 1 are fastened to arm-like needle reed supports 71 which are screwed onto a second associated needle reed shaft 72 which is rotatably mounted in the machine frame 20. A radial arm 73 is connected to the needle reed shaft 72 or a needle reed support 71, to which a coupling rod 74 is articulated, which at its other end is connected in an articulated manner to the weaving support 23 at the same articulation point as the rod 61.
Im Betrieb führen deshalb beide Nadelriete 7, 8 eine im Wesentlichen quer zu der Webebene 42 gerichtete, auf- und abgehende Bewegung aus, die die von ihnenjeweils geführten Steher- bzw. Dreherfäden 1, 2 mitmachen und die mit der hin- und hergehenden Bewegung des Webblatts 9 exakt synchronisiert ist, weil die Bewegung der Nadelriete 7, 8 von der Webblattwelle 24 abgeleitet ist. Die parallel zur Webebene 42 erfolgende, horizontale Versatzbewegung der Dreherfäden 2 wird, wie erwähnt, über das Kurvengetriebe 63 erzeugt, so dass sich die in dem Diagramm der Figur 2 unten dargestellten und aus dem Vorstehenden ohne Weiteres verständlichen Bewegungsabläufe der „dritten Art" ergeben, wobei im Gegensatz zu dem Diagramm hier als Alternative die Dreherfäden 2 und nicht die Steherfaden 1 seitlich versetzt werden.In operation, therefore, both needle reeds 7, 8 execute an upward and downward movement which is essentially transverse to the weaving plane 42 and which the upright or leno threads 1, 2 each guide and which move along with the reciprocating movement of the The reed 9 is precisely synchronized because the movement of the needle reeds 7, 8 is derived from the reed shaft 24. As mentioned, the horizontal offset movement of the leno threads 2 parallel to the weaving plane 42 is generated via the cam mechanism 63, so that the movement sequences of the “third type” shown in the diagram in FIG. 2 below and easily understandable from the foregoing result, in contrast to the diagram here, the leno threads 2 and not the upright thread 1 are laterally offset as an alternative.
Für alle Ausführungsfonnen gilt, dass der Antrieb der Nadelrietwelle 37 auch als Außenantrieb ein- oder beidseitig vorgesehen werden kann. Wird, wie dargestellt, die Nadelrietwelle 37 unterhalb des Hinterfaches angeordnet, so kann für sie ein Mehrfachantrieb über die Webbreite angewandt werden. Alternaiv kann aber die Nadelrietwelle 37 auch oberhalb des Hinterfaches 1 iegen.It applies to all embodiments that the drive of the needle shaft 37 can also be provided as an external drive on one or both sides. If, as shown, the needle reed shaft 37 is arranged below the rear compartment, a multiple drive over the weaving width can be used for it. Alternatively, the needle reed shaft 37 can also lie above the rear compartment 1.
Die kreisförmige Schwenkbewegung des Nadelriets 7 - und bei der Ausfuhrungsform nach Fig. 14 auch des Nadelriets 8 - ermöglicht, dass, wie bereits erwähnt, die Fadenaugen 33 der Nadelriete 7, 8 in der Geschlossen-Fach-Stellung nach Fig. 8 nahe beieinander stehen. Zusammen mit den anhand der Figuren 4 bis 6 erläuterten Ausbildung der Nadeln 32 ergibt sich dadurch eine sehr präzise Führung der Steher- und der Dreherfäden 1 bzw. 2. Der Einsatz des Webladenantriebes für den Nadelrietantrieb führt nicht nur zu einfachen konstruktivenThe circular pivoting movement of the needle reed 7 - and in the embodiment according to FIG. 14 also of the needle reed 8 - enables, as already mentioned, the thread eyes 33 of the needle reeds 7, 8 to be close to each other in the closed compartment position according to FIG. 8. Together with the design of the needles 32, which is explained with reference to FIGS. 4 to 6, this results in a very precise guidance of the upright and leno threads 1 and 2
Verhältnissen, sondern f hrt auch zu einer Konstruktion mit geringen bewegten trägen Massen. Gleichzeitig ist ein präziser Seitenwechsel der Steherfäden 1 zu den Dreherfäden 2 bei dem Web Vorgang gewährleistet. Schließlich zeichnet sich die neue Webmaschine in allen Ausführungsformen, wie erläutert, durch eine bedienungsfreundliche Anordnung der Nadelriete 7, 8 für die Kettfadenb ruchbehebung aus. Die Hubweiten für die Nadelriete 7, 8 kömien darüber hinaus mit einfachen Mitteln leicht bedarfsgerecht verstellt werden.Conditions, but also leads to a construction with low moving inertial masses. At the same time, a precise change of sides of the upright threads 1 to the leno threads 2 is ensured in the weaving process. Finally, the new weaving machine is characterized in all embodiments, as explained, by a user-friendly arrangement of the needle reeds 7, 8 for eliminating the warp threads. The stroke widths for the needle reeds 7, 8 can also be easily adjusted as required using simple means.
Der im Vorstehenden anhand mehrerer Ausführungsformen beschriebene erfindungsgemäße Gedanke kann nicht nur beim Bau neuer Webmaschinen verwirklicht werden, sondern er kann auch dazu benutzt werden, durch entsprechende Zusatzeinrichtungen oder Umbauten bestehende Webmaschinen verschiedener Systeme und unterschiedlicher Arten des Schussfadeneintrags erfindungsgemäß auszurüsten oder umzustellen. The inventive idea described above with reference to several embodiments can not only be realized in the construction of new weaving machines, but it can also be used to equip or convert existing weaving machines of different systems and different types of weft insertion according to the invention by means of corresponding additional devices or conversions.
