Definitions
- the invention relates to a jacquard strand for use in Jacquard machines.
- Jacquard strands are for example according to GB 807945 made by first soldering two adjacent wires together. The brazed wires are then separated again in one area and bent slightly apart. In the resulting opening then a Fadenaug DNS (Maillon) is soldered, which forms the thread eye.
- Fadenaug DNS Fadenaug DNS
- Remedy creates the DE 121 105 , which emanates from the production of the heald from a relatively thick wire. While a central portion of the wire initially remains undeformed, the two axially adjacent portions are axially stretched so that their diameter decreases. The remaining thick central area is then flattened to a thickness corresponding to the diameter of the stretched areas. In the resulting oval flattened area is then in turn punched an oval opening into which a Fadenaugfoli can be used.
- the EP 1 767 676 deals in a way supplementary to the aforementioned document with the improvement of the attachment option for the Fadenaugrum.
- the strand shown there is based on a round wire on which a flattened area is attached. In these an opening is punched, which is bounded by two remaining flat legs. The opening is narrower than a thread eye to be inserted. In order to achieve the required width, the remaining legs are wound in the longitudinal direction, so that they are inclined in cross section to the thread eye.
- the resulting asymmetry of the shape is disadvantageous during weaving, but in particular with regard to the passage of the threads running alongside the strand.
- the above disadvantages should be avoided as much as possible.
- the jacquard strand according to the invention has a strand body which consists of a round material. This is provided with a flattened portion having a widened bounded by two legs opening. The two legs have a common cross-sectional area, which coincides with the cross-sectional area of the round Litzen stresses. The tensile strength of the strand is in the flattened portion, in the region of the eye thus approximately as large as in the areas spaced from the eye.
- round wire can be used as the starting material for the production of the strand, which is available as a semi-finished product at low cost. Hard-to-control and thus quality defects causing manufacturing steps, such as local stretching of the wire are avoided.
- the (round wire) strand is narrow. So that it is hardly worn by the running through between the strands warp threads. The service life is correspondingly high. The jacquard strand change associated with high personnel expenditure can be reduced to a minimum.
- the narrow width of the jacquard strand according to the invention in comparison with flat strip strands or double stranded strands also allows the production of comparatively dense jacquard fabrics.
- the jacquard strand according to the invention is preferably symmetrical with respect to a median plane on which the opening direction the thread eye is vertical. Front and back of Jacquardweblitze are the same in particular on the thread eye. This protects the warp threads.
- the strands according to the invention can be optimized in terms of their weight. Because of the material cross section which is largely constant along the longitudinal direction and the resulting constant tensile strength, the heddle can be produced over its entire length with minimal use of material. This is advantageous in view of the conditions encountered in jacquard machines. As a rule, jacquard machines have a negative shedding. This means that the strands are held in the lower position with springs or weights and are brought into the upper compartment position only by the tensile force of the respective harness cord. The lighter the strands, the lower the required force. Correspondingly lower, the counterforce can also fail, i. the lighter or weaker the weights or springs that pull the strands down can fail. As a result, the energy consumption of a jacquard machine can be reduced.
- the strand of the invention causes in their production no or only a very minimal material waste, which is particularly important when using high-quality steels or stainless steels and stainless steels.
- the cross sections of the legs enclosing the opening are produced by plastic deformation without (significant) material removal from the cross section of the starting material.
- the strand according to the invention can, starting from a round wire, are produced, ie consist of metal. she can but also be made of a plastic material, such as a carbon fiber or glass fiber composite. Also in the plastic variant, the sum of the area contents of the leg cross sections coincides with the area of the round cross section. Depending on the manufacturing method, the sum of the surface areas of the leg cross sections may differ slightly from the surface area of the round cross section. Thus, it is possible that in the mechanical production of the leg cross-sections, a material flow takes place in the longitudinal direction of the strand according to the invention, which can slightly influence the cross-sectional ratios. The two legs then have a common cross-sectional area, which largely coincides with the cross-sectional area of the round litz body.
- a Fadenaugieri is preferably held. This can preferably be glued. It is also possible to fix it by means of a solder or a weld.
- the Fadenaugiller on its outer periphery on a circumferential groove. The legs of the strand bent away from each other nestle into this channel and hold the thread eye insert.
- the outer contour of the Fadenaug respondentses adapted optimally to the cross section of the legs, i. they are congruent with each other can be attached to an attachment of the Fadenaugmbies. be dispensed with by soldering or gluing because there is a positive connection between the outer contour of the FadenaugDCes and the legs.
- the wire cross-section is preferably determined by using the size Fadenaugfuges is assumed. From the thickness of the Fadenaugfuges arise the cross sections of the two wire-shaped legs, which engage in the outside of the thread eye insert gutter. The sum of these two substantially round leg cross-sections, which usually have a diameter of 0.3 to 0.4 mm, gives the wire cross-section of then, for example, 0.42 mm to 0.57 mm. Preferably, a wire diameter of 0.5 mm is used because the legs are then given a diameter of about 0.35 mm. This corresponds to the dimensions that are suitable for the most commonly used Fadenaugein engines today.
- the strand according to the invention is produced, for example, by embossing, by producing a flattened region on a round wire which has a longitudinal groove on both flat sides.
- the two longitudinal grooves have a matching shape.
- an octagonal cross-section has been formed on the round wire at the relevant point.
- two legs can be separated and pulled apart. The result is an opening in which a Fadenaug senator can be inserted.
- the two separate legs then have an at least nearly round cross-section, wherein the cross-sectional ratios according to the invention are maintained.
- the shape achieved in this way fulfills all requirements with regard to thread-friendliness with regard to the threads running past the outside of the strand.
- the attachment of the Fadenaug cities is easy, because the cross sections of the legs fit into the outer groove or gutter of Fadenaugfuges.
- the outer shape of the two legs is preferably round, they can on the mutually facing flanks have a protruding into the opening rib, which engages particularly well in the groove of the Fadenaug denses, so that it is held securely.
- Fadenaugmbies By attaching the Fadenaugmbies in bonding technology, it is possible to use as starting material for the strand a difficult or non-solderable material, such as stainless steel. In addition, adhesive as a fastening material contributes less to the strand weight than a corresponding solder.
- the transition between the flat cross section and the circular cross section is achieved by a stepless transition zone in which the individual cross sections change continuously along the axial direction of the heddle. Any abrupt or step-like cross-sectional changes are preferably avoided.
- FIG. 1 is a jacquard 1 illustrated, which is intended for use in Jacquard looms. It has an elongated Litzenköper 2, which is provided at its ends with fastening means, for example in the form of eyelets 3, 4.
- the heald body 2 consists for example of a wire, for example a stainless steel wire. But it can also consist of another suitable material, such as plastic.

- the cross section of the shank leg 10 or 11 gradually transitions over a transitional cross section 9a in a flat cross section.
- the circular cross-section of the shaft leg 10 or 11 has a cross-sectional area A1, which at the section line VII-VII in FIG. 2 is to measure and along the shaft 20 of the Jacquard, which is formed by its legs 10 or 11, preferably unchanged.

Es ist Aufgabe der vorliegenden Erfindung eine Jacquard-litze zu schaffen, die sich ohne Kompromisse hinsichtlich der Qualität kostengünstig fertigen lässt. Die oben dargestellten Nachteile sind möglichst zu vermeiden.It is an object of the present invention to provide a jacquard strand, which without compromise in terms of Produce quality cost-effectively. The above disadvantages should be avoided as much as possible.
Diese Aufgabe wird mit der Jacquardlitze nach Anspruch 1 gelöst:This object is achieved with the Jacquardlitze according to claim 1:
Die erfindungsgemäße Jacquardlitze weist einen Litzenkörper auf, der aus einem Rundmaterial besteht. Dieses ist mit einem abgeflachten Abschnitt versehen, der eine aufgeweitete von zwei Schenkeln umgrenzte Öffnung aufweist. Die beiden Schenkel haben gemeinsam eine Querschnittsfläche, die mit der Querschnittsfläche des runden Litzenkörpers übereinstimmt. Die Zugfestigkeit der Litze ist in dem abgeflachten Abschnitt, im Bereich des Öhrs somit in etwa so groß wie in den vom Öhr beabstandeten Bereichen. Zudem kann als Ausgangsmaterial zur Herstellung der Litze Runddraht verwendet werden, der als Halbfabrikat kostengünstig verfügbar ist. Schwer zu beherrschende und somit auch Qualitätsmängel verursachende Fertigungsschritte, wie zum Beispiel lokales Strecken des Drahts werden vermieden. Außerdem ist die (Runddraht-)Litze schmal. So dass sie von den zwischen den Litzen durchlaufenden Kettfäden kaum verschlissen wird. Entsprechend hoch ist die Standzeit. Der mit hohem Personalaufwand verbundene Jacquardlitzenwechsel kann auf ein Minimum reduziert werden.The jacquard strand according to the invention has a strand body which consists of a round material. This is provided with a flattened portion having a widened bounded by two legs opening. The two legs have a common cross-sectional area, which coincides with the cross-sectional area of the round Litzenkörpers. The tensile strength of the strand is in the flattened portion, in the region of the eye thus approximately as large as in the areas spaced from the eye. In addition, round wire can be used as the starting material for the production of the strand, which is available as a semi-finished product at low cost. Hard-to-control and thus quality defects causing manufacturing steps, such as local stretching of the wire are avoided. In addition, the (round wire) strand is narrow. So that it is hardly worn by the running through between the strands warp threads. The service life is correspondingly high. The jacquard strand change associated with high personnel expenditure can be reduced to a minimum.
Die im Vergleich zu Flachbandlitzen oder Doppeldrahtlitzen geringe Breite der erfindungsgemäßen Jacquardlitze gestattet außerdem die Erzeugung von vergleichsweise dichten Jacquardgeweben.The narrow width of the jacquard strand according to the invention in comparison with flat strip strands or double stranded strands also allows the production of comparatively dense jacquard fabrics.
Die erfindungsgemäße Jacquardlitze ist vorzugsweise bezüglich einer Mittelebene symmetrisch, auf der die Öffnungsrichtung des Fadenauges senkrecht steht. Vorderseite und Rückseite der Jacquardweblitze sind insbesondere an dem Fadenauge gleich. Dies schont die Kettfäden.The jacquard strand according to the invention is preferably symmetrical with respect to a median plane on which the opening direction the thread eye is vertical. Front and back of Jacquardweblitze are the same in particular on the thread eye. This protects the warp threads.
Außerdem sind die erfindungsgemäßen Litzen hinsichtlich ihres Gewichts optimierbar. Wegen des entlang der Längsrichtung weitgehend konstanten Materialquerschnitts und der sich daraus ergebenden konstanten Zugfestigkeit kann die Weblitze über ihre gesamte Länge mit minimalem Materialeinsatz hergestellt werden. Im Hinblick auf die in Jacquardmaschinen anzutreffenden Verhältnisse ist dies vorteilhaft. In der Regel liegt bei Jacquardmaschinen eine negative Fachbildung vor. Diese bedeutet, dass die Litzen mit Federn oder Gewichten in Unterfachposition gehalten und nur durch die Zugkraft der jeweiligen Harnischschnur in Oberfachposition gebracht werden. Je leichter die Litzen sind, desto geringer ist die dazu erforderliche Kraft. Entsprechend geringer kann auch die Gegenkraft ausfallen, d.h. desto leichter bzw. schwächer können die Gewichte oder Federn ausfallen, die die Litzen nach unten ziehen. Dadurch kann der Energieverbrauch einer Jacquardmaschine verringert werden.In addition, the strands according to the invention can be optimized in terms of their weight. Because of the material cross section which is largely constant along the longitudinal direction and the resulting constant tensile strength, the heddle can be produced over its entire length with minimal use of material. This is advantageous in view of the conditions encountered in jacquard machines. As a rule, jacquard machines have a negative shedding. This means that the strands are held in the lower position with springs or weights and are brought into the upper compartment position only by the tensile force of the respective harness cord. The lighter the strands, the lower the required force. Correspondingly lower, the counterforce can also fail, i. the lighter or weaker the weights or springs that pull the strands down can fail. As a result, the energy consumption of a jacquard machine can be reduced.
Die erfindungsgemäße Litze verursacht bei ihrer Fertigung keinen oder nur einen ganz minimalen Materialverschnitt, was insbesondere bei Verwendung hochwertiger Stähle oder rostfreier Stähle sowie Edelstähle von Bedeutung ist. Die Querschnitte der die Öffnung umschließenden Schenkel sind durch plastische Umformung ohne (nennenswerten) Materialabtrag aus dem Querschnitt des Ausgangsmaterials erzeugt.The strand of the invention causes in their production no or only a very minimal material waste, which is particularly important when using high-quality steels or stainless steels and stainless steels. The cross sections of the legs enclosing the opening are produced by plastic deformation without (significant) material removal from the cross section of the starting material.
Die erfindungsgemäße Litze kann, ausgehend von einem Runddraht, erzeugt werden, d.h. aus Metall bestehen. Sie kann aber auch aus einem Kunststoffmaterial gefertigt werden, beispielsweise aus einem Kohlefaser- oder Glasfaser-Verbundstoff. Auch in der Kunststoffvariante stimmt die Summe der Flächeninhalte der Schenkelquerschnitte mit dem Flächeninhalt des Rundquerschnitts überein. Abhängig von der Herstellmethode kann die Summe der Flächeninhalte der Schenkelquerschnitte geringfügig von dem Flächeninhalt des Rundquerschnitts abweichen. So ist es möglich, dass bei der mechanischen Herstellung der Schenkelquerschnitte ein Materialfluss in Längsrichtung der erfindungsgemäßen Litze erfolgt, der die Querschnittsverhältnisse geringfügig beeinflussen kann. Die beiden Schenkel haben dann gemeinsam eine Querschnittsfläche, die mit der Querschnittsfläche des runden Litzenkörpers weitgehend übereinstimmt.The strand according to the invention can, starting from a round wire, are produced, ie consist of metal. she can but also be made of a plastic material, such as a carbon fiber or glass fiber composite. Also in the plastic variant, the sum of the area contents of the leg cross sections coincides with the area of the round cross section. Depending on the manufacturing method, the sum of the surface areas of the leg cross sections may differ slightly from the surface area of the round cross section. Thus, it is possible that in the mechanical production of the leg cross-sections, a material flow takes place in the longitudinal direction of the strand according to the invention, which can slightly influence the cross-sectional ratios. The two legs then have a common cross-sectional area, which largely coincides with the cross-sectional area of the round litz body.
In der von den beiden Schenkeln begrenzten Öffnung ist vorzugsweise ein Fadenaugeinsatz gehalten. Dieser kann vorzugsweise eingeklebt sein. Es ist auch möglich ihn mittels eines Lots oder durch eine Schweißung zu fixieren. Vorzugsweise weist der Fadenaugeinsatz an seinem Außenumfang eine umlaufende Rinne auf. Die voneinander weg gebogenen Schenkel der Litze schmiegen sich in diese Rinne und halten den Fadenaugeinsatz. Ist die Außenkontur des Fadenaugeinsatzes optimal auf den Querschnitt der Schenkel angepasst d.h. sie sind kongruent zueinander ausgebildet kann auf eine Befestigung des Fadenaugeinsatzes z.B. durch Löten bzw. Kleben verzichtet werden da zwischen der Außenkontur des Fadenaugeinsatzes und den Schenkeln ein Formschluss entsteht.In the limited by the two legs opening a Fadenaugeinsatz is preferably held. This can preferably be glued. It is also possible to fix it by means of a solder or a weld. Preferably, the Fadenaugeinsatz on its outer periphery on a circumferential groove. The legs of the strand bent away from each other nestle into this channel and hold the thread eye insert. Is the outer contour of the Fadenaugeinsatzes adapted optimally to the cross section of the legs, i. they are congruent with each other can be attached to an attachment of the Fadenaugeinsatzes. be dispensed with by soldering or gluing because there is a positive connection between the outer contour of the Fadenaugeinsatzes and the legs.
Bei der Verwendung eines dünnen runden Drahts mit Rundquerschnitt zur Herstellung der Litze wird der Drahtquerschnitt vorzugsweise festgelegt, indem von der Größe zu verwendenden Fadenaugeinsatzes ausgegangen wird. Aus der Dicke des Fadenaugeinsatzes ergeben sich die Querschnitte der beiden drahtförmigen Schenkel, die in die an dem Fadenaugeinsatz außen verlaufende Rinne eingreifen. Die Summe dieser beiden im Wesentlichen runden Schenkelquerschnitte, die üblicherweise einen Durchmesser von 0,3 bis 0,4 mm haben, ergibt den Drahtquerschnitt von dann zum Beispiel 0,42 mm bis 0,57 mm. Vorzugsweise wird mit einem Drahtdurchmesser von 0,5 mm gearbeitet, weil die Schenkel dann einen Durchmesser von ca. 0,35 mm erhalten. Dies entspricht den Maßen, die für die heutzutage meist verwendeten Fadenaugeinsätze passen.When using a thin round-sectioned round wire to make the strand, the wire cross-section is preferably determined by using the size Fadenaugeinsatzes is assumed. From the thickness of the Fadenaugeinsatzes arise the cross sections of the two wire-shaped legs, which engage in the outside of the thread eye insert gutter. The sum of these two substantially round leg cross-sections, which usually have a diameter of 0.3 to 0.4 mm, gives the wire cross-section of then, for example, 0.42 mm to 0.57 mm. Preferably, a wire diameter of 0.5 mm is used because the legs are then given a diameter of about 0.35 mm. This corresponds to the dimensions that are suitable for the most commonly used Fadenaugeinsätze today.
Die erfindungsgemäße Litze wird zum Beispiel durch Prägeformen hergestellt, indem an einem Runddraht ein abgeflachter Bereich erzeugt wird, der an beiden Flachseiten jeweils eine Längsnut aufweist. Vorzugsweise haben die beiden Längsnuten eine miteinander übereinstimmende Form. An dem Runddraht ist dadurch an der betreffenden Stelle ein achtförmiger Querschnitt entstanden. Hier können zwei Schenkel voneinander getrennt und auseinander gezogen werden. Es entsteht eine Öffnung in der ein Fadenaugeinsatz eingefügt werden kann. Die zwei voneinander getrennten Schenkel weisen dann einen zumindest nahezu runden Querschnitt auf, wobei die erfindungsgemäßen Querschnittsverhältnisse eingehalten werden. Die so erreichte Form erfüllt alle Ansprüche hinsichtlich der Fadenfreundlichkeit bezüglich der außen an der Litze vorbeilaufenden Fäden. Zugleich ist die Befestigung des Fadenaugeinsatzes einfach, weil die Querschnitte der Schenkel in die äußere Rille bzw. Rinne des Fadenaugeinsatzes passen.The strand according to the invention is produced, for example, by embossing, by producing a flattened region on a round wire which has a longitudinal groove on both flat sides. Preferably, the two longitudinal grooves have a matching shape. As a result, an octagonal cross-section has been formed on the round wire at the relevant point. Here, two legs can be separated and pulled apart. The result is an opening in which a Fadenaugeinsatz can be inserted. The two separate legs then have an at least nearly round cross-section, wherein the cross-sectional ratios according to the invention are maintained. The shape achieved in this way fulfills all requirements with regard to thread-friendliness with regard to the threads running past the outside of the strand. At the same time, the attachment of the Fadenaugeinsatzes is easy, because the cross sections of the legs fit into the outer groove or gutter of Fadenaugeinsatzes.
Während die Außenform der beiden Schenkel vorzugsweise rund ist, können sie an den aufeinander zuweisenden Flanken eine in die Öffnung vorstehende Rippe aufweisen, die besonders gut in die Rille des Fadenaugeinsatzes eingreift, so dass dieser gut sicher gehalten wird.While the outer shape of the two legs is preferably round, they can on the mutually facing flanks have a protruding into the opening rib, which engages particularly well in the groove of the Fadenaugeinsatzes, so that it is held securely.
Beim Trennen der Schenkel reißt ein dünner zwischen den Schenkeln vorhandener Steg, wobei der Riss in Litzenlängsrichtung verläuft. An den Enden der Rillen oder in der Nähe der Enden können Querbohrungen angebracht werden, die beim Trennen der Schenkel als Rissstopper dienen.When separating the legs tears a thin existing between the legs web, wherein the crack runs in the longitudinal direction of the strand. At the ends of the grooves or near the ends transverse bores can be attached, which serve as a crack stopper when separating the legs.
Durch das Befestigen des Fadenaugeinsatzes in Klebetechnik wird es möglich, als Ausgangsmaterial für die Litze ein schwer oder nicht lötbares Material, wie beispielsweise rostfreien Stahl zu verwenden. Außerdem trägt Klebstoff als Befestigungsmaterial weniger zum Litzengewicht bei als ein entsprechendes Lot.By attaching the Fadenaugeinsatzes in bonding technology, it is possible to use as starting material for the strand a difficult or non-solderable material, such as stainless steel. In addition, adhesive as a fastening material contributes less to the strand weight than a corresponding solder.
Vorzugsweise wird der Übergang zwischen dem Flachquerschnitt und dem Rundquerschnitt durch eine stufenlose Übergangszone erreicht, in der sich die einzelnen Querschnitte entlang der Axialrichtung der Weblitze stetig verändern. Irgendwelche abrupten oder stufenartigen Querschnittsänderungen werden vorzugsweise vermieden.Preferably, the transition between the flat cross section and the circular cross section is achieved by a stepless transition zone in which the individual cross sections change continuously along the axial direction of the heddle. Any abrupt or step-like cross-sectional changes are preferably avoided.
