Definitions
- the invention relates to a flat band heddle with end eyelet, shaft and thread eye, made of a metal band section.
- Healds for example, made of flat steel strip in a punching process. It will be removed from a metal band blanks games to obtain the desired outer shape of the heald. The removed parts are waste, but this contributes significantly to the material consumption.
- adjacent healds on a heald are often cranked away in opposite directions from each other. This creates an offset between the thread eyes of adjacent healds with respect to the warp thread longitudinal direction to facilitate the passage of warp threads between the healds.
- Paired healds with different staggered shafts are from the US Pat. No. 7,204,274 B2 and the CH 468 489 and the DE 10 2005 033 175 B3 known. These heddles each have a straight edge extending along the shaft and the end eyelet. The achievable gap between the shafts of adjacent healds is limited.
- healds on flat material each forming a relatively narrow sheet metal strip.
- the end loops are symmetrically connected to the shank, which may be provided with a bend to define an enlarged yarn passage between adjacent healds.
- the healds are made of a metallic sheet.
- the shafts of the healds are designed so that there is an enlarged thread passage space between adjacent healds.
- a heddle which is made of a narrow sheet metal strip, have been prepared in the thread eye and end eyelet in slotted sections by widening.
- the shaft of such a heddle can be formed cranked.
- the shank On both sides of the thread eye, the shank has been flattened in an embossing process in order to bring about increased elasticity in warp thread longitudinal direction.
- Such a heald can be made of a metal strip whose width is not greater than the width of the end eyelets. Nevertheless, in KettfadenlCodescardi a large offset between the thread eye and Endulate can be achieved.
- the shaft is subsequently arranged offset relative to the end eyelets.
- This after cutting or punching the heald not yet available but subsequently generated offset the shaft against the end loops is achieved by a plastic deformation of the transition region or a part of the shaft within said plane. This is done by means of a corresponding embossing process. But it is also possible to integrate the punching and embossing into one step and to perform in a common tool. Again, there is a plastic deformation of the shaft or transition region to form the crank or the offset.
- FIG. 1 For example, a ribbon hank blank 1 is illustrated that has been stamped from a width B metal strip. This width B is lower than usual for punched flat band healds.
- the flat-heddle web blank 1 has two end loops 2, 3, between which a shaft 4 is provided. This connects via transition areas 5, 6 to the end eyelets.
- openings 7, 8 have been introduced into the end regions of the sheet-metal strip section in order to form the end eyelets 2, 3. These openings may have a closed edge or, as shown, also a broken edge.
- O-end eyelets such as for example FIG. 8
- C-end eyelets (as in Figure 1 to 6 )
- J-end eyelets as in FIG. 7 ).
- the flat-band heddle blank 1 has a straight edge 9 which extends from the upper end of the upper end eyelet 7 to the lower end of the lower end eyelet 8.
- This straight edge 9 corresponds to a side edge of the original metal band section. From the opposite straight edge, however, only two sections 10, 11 are left at the end eyes 2, 3.
- material was removed from the metal band portion (e.g., in a punching or cutting operation), thereby forming inward edge portions 12, 13 and an inwardly offset edge portion 14.
- the shaft 4 has also been provided with a thread eye 15, in which a corresponding opening has been introduced at the desired location. Further openings 16, 17 can be provided on the end eyes 2, 3 or in the transitional areas 5, 6.
- FIG. 12 illustrates another ribbon heald bladder 18. While in the flat ribbon heald frame 1, the straight continuous edge 9 is located on the side of the edge interruption of the openings 7, 8, this continuous edge 9 in the flat-heddle wire blank 18 after FIG. 2 arranged on the other side of the blank and thus extends over the closed edges of the end loops 2, 3 continuously away.
- the sections 10, 11 are arranged on the sides of the end loops 2, 3, at which the edge thereof is interrupted. The same applies to the edge portions 12, 13, 14. Otherwise, the description of the flat-heddle wire blank 1 applies correspondingly to the heald wire 18 based on the same reference numerals.
- the heddle blanks 1, 18 therefore undergo a further processing step, for example an embossing step, in the course of which they undergo, for example, an offset away from one another in the transitional areas 5, 6. They are deformed within the plane defined by the end eyelets 2, 3 and the shaft 4 so that the thread eye 15 is located on an imaginary line 19, as the former position of the edge 9 marked.
- This imaginary line 19 connects remaining portions 9a, 9b of the edge 9, which are still present at the end eyelets 2, 3.
- the thread eye 15 lies with its center on the line 19 or is beyond this outwards, ie in FIG. 4 bent to the left. It is arranged in the middle section 9c of the former edge 9. This section 9c is at a distance X to the Line 19.
- the distance X is preferably at least as large as half the width B1 of the shaft 4 in the region of the thread eye 15.
- the edge 9 is divided in the forming process into sections, namely the sections 9a, 9b, which lie on the line 19 and pass with an outwardly directed bend or arc into sections 9d, 9e which lead the edge away from the line 19 and merge into the central section 9c, which in turn is straight.
- the ribbon heald 20 produced in this way requires a smaller amount of material for its production than healds punched out of a correspondingly wider metal band section. Compared to healds with flared end loops, there are fewer local material deformations. The choice of material can be optimized.
- a complementary flat ribbon heald 21 can be produced from the ribbon heald 18. Again, a forming process is carried out, during which the center of the shaft 4 is brought to the line 19, which marks the former course of the edge 9. The edge 9 is thereby divided into the sections 9a, 9b, 9c, 9d, 9e.
- the previous description of the ribbon heald wire blank 18 and the flatweave heald 20 applies correspondingly on the basis of the same reference numerals.
- FIG. 6 Be the flat-band heddles 20, 21, such FIG. 6 illustrates, suitably superimposed, as they are lined up on mounting rails, it turns out that the shanks 4 are bent away from each other. It therefore arises in the field of thread eyes 15 between the edge portions 14 of the shafts 4, a distance R, which is substantially greater than the distance D according to FIG. 3 ,
- the distance R is preferably as large as half the width B1 of the shaft 4, ideally as large as the width B1 of the shaft 4.
- FIG. 7 illustrates a modified heald pair 22 with J-shaped end eyelets 2, 3. Incidentally, the above statements apply accordingly on the basis of the same reference numerals.
- the offset of the portion 9c of the edge 9 in all previous embodiments is arranged on the transitional sections 5, 6, it is also possible to lay this offset in the region of the shaft 4.
- the transition region 5 reduces the width of the heald from the greater width B in the region of the end eyelet 2 to the smaller width A of the shaft 4
- the straight portion 9a of the edge 9 extends both over the end eyelet 2 and over the transition region 5
- the adjoining shank 4 is bent, so that the section 9d of the edge 9 lies in the region of the shank 4. Again, immediately adjoins the straight portion 9a via a bow or a bend of the outwardly facing portion 9d.
- the healds according to the invention consist of a metal strip section of width B which is narrower than the total width B + X required for the flat stranded strand 20.
- the flat stranded strand 20 has a substantially unprocessed, in any case uncircumferential, originating from the metal strip portion edge 9 and an edge 10, 11, 12, 13, 14 which has been generated in the region of the shaft 4 and the transition sections 5, 6 by trimming the metal strip portion ,
- An outward turn of the shaft 4 creates an increased distance R between two associated oppositely cranked flat-band healds of a heald pair 23, to which two oppositely cranked flat-band healds 20, 21 belong.

Description
Die Erfindung betrifft eine Flachband-Weblitze mit Endöse, Schaft und Fadenauge, hergestellt aus einem Metallbandabschnitt.The invention relates to a flat band heddle with end eyelet, shaft and thread eye, made of a metal band section.
Weblitzen werden beispielsweise aus flachem Stahlband in einem Stanzvorgang hergestellt. Dabei werden von einem Metallbandzuschnitt Partien entfernt, um die gewünschte Außenform der Weblitze zu erhalten. Die entfernten Teile sind Abfall, der aber zum Materialverbrauch erheblich beiträgt.Healds, for example, made of flat steel strip in a punching process. It will be removed from a metal band blanks games to obtain the desired outer shape of the heald. The removed parts are waste, but this contributes significantly to the material consumption.
Es ist manchmal erforderlich, Weblitzen mit einer Kröpfung zu versehen, wobei insbesondere benachbarte Weblitzen auf einen Webschaft häufig in entgegen gesetzten Richtungen voneinander weg gekröpft sind. Dadurch entsteht bezüglich der Kettfadenlängsrichtung ein Versatz zwischen den Fadenaugen benachbarter Weblitzen, um den Durchgang von Kettfäden zwischen den Weblitzen zu erleichtern.

Zwar ist das Herstellen von länglichen Öffnungen durch Schlitzen und Aufweiten ein materialsparendes Verfahren, jedoch setzt es eine relativ starke Materialverformung voraus, was die Materialwahl und die Möglichkeiten der Materialoptimierung einschränkt.Although the production of elongated openings by slitting and widening is a material-saving process, but it requires a relatively strong material deformation, which limits the choice of materials and the possibilities of material optimization.
Es ist Aufgabe der Erfindung, eine Weblitze und ein zu ihrer Herstellung dienendes rationelles Herstellungsverfahren anzugeben, womit eine materialsparende Herstellung hochleistungsfähiger Weblitzen ermöglicht werden soll.It is an object of the invention to provide a heald and serving for their production rational production method, which should be a material-saving production of high-performance healds to be made possible.
Diese Aufgabe wird mit der Flachband-Weblitze nach Anspruch 1, wie auch mit dem Verfahren nach Anspruch 8 gelöst:
- Die erfindungsgemäße Flachbandweblitze besteht aus einem Metallbandabschnitt, dessen ursprüngliche Breite der Breite an der Endöse entspricht. Entlang des Schafts ist Material entfernt worden, beispielsweise in einem Stanzvorgang oder dergleichen. Zwischen der Endöse und dem Schaft ist ein Übergangsabschnitt ausgebildet, in dem sich die Breite von der Endösenbreite auf die Schaftbreite reduziert. Die Weblitze weist an der Endöse eine gerade Kante auf, die in einigem Abstand zu der Endöse entweder an dem Übergangsabschnitt oder an dem Schaft einen von einer Längsmittellinie der Weblitze in einem Knick oder Bogen weg führenden Abschnitt aufweist. Dadurch ist die Außenkante des Schafts um einen Betrag X versetzt. Die Mitte des Fadenauges liegt vorzugsweise ungefähr auf einer Linie, die die Außenkanten der Endösen miteinander verbindet.
- The Flachbandweblitze invention consists of a metal strip portion whose original width corresponds to the width at the Endöse. Material has been removed along the shaft, for example in a punching process or the like. Between the end eyelet and the shaft, a transition section is formed, in which the width is reduced from the end eyelet width to the shaft width. The heald has a straight edge on the end eyelet which, at some distance from the end eyelet, has either a portion leading away from a longitudinal centerline of the heald, at either the transitional portion or on the shaft, in a kink or bow. As a result, the outer edge of the shaft is offset by an amount X. The center of the thread eye is preferably approximately on a line connecting the outer edges of the end eyelets.
Eine solche Weblitze lässt sich aus einem Metallstreifen herstellen, dessen Breite nicht größer ist als die Breite der Endösen. Dennoch kann in Kettfadenlängsrichtung ein großer Versatz zwischen Fadenauge und Endöse erreicht werden.Such a heald can be made of a metal strip whose width is not greater than the width of the end eyelets. Nevertheless, in Kettfadenlängsrichtung a large offset between the thread eye and Endöse can be achieved.
Ausgehend von einer zunächst flach ausgebildeten Flachbandweblitze, die vorzugsweise eben, d.h. unverwunden ausgebildet ist und somit deren Endöse, Übergangsabschnitt und Schaft in einer gemeinsamen Ebene, vorzugsweise gegeneinander nicht verdreht angeordnet sind, wird der Schaft nachträglich gegenüber den Endösen versetzt angeordnet. Dieser nach dem Ausschneiden bzw. Ausstanzen der Weblitze noch nicht vorhandene sondern nachträglich erzeugte Versatz des Schafts gegen die Endösen wird durch eine plastische Verformung des Übergangsbereichs oder eines Teils des Schafts innerhalb der genannten Ebene erreicht. Dazu dient ein entsprechendes Prägeverfahren. Es ist aber auch möglich, das Stanzen und Prägen zu einem Schritt zu integrieren und in einem gemeinsamen Werkzeug durchzuführen. Auch hier kommt es zu einer plastischen Verformung an Schaft oder Übergangsbereich zur Ausbildung der Kröpfung bzw. des Versatzes.Starting from a flat initially trained Flachbandweblitze, which is preferably flat, ie unbound formed and thus their Endöse, transition portion and shaft in a common plane, preferably not rotated against each other, the shaft is subsequently arranged offset relative to the end eyelets. This after cutting or punching the heald not yet available but subsequently generated offset the shaft against the end loops is achieved by a plastic deformation of the transition region or a part of the shaft within said plane. This is done by means of a corresponding embossing process. But it is also possible to integrate the punching and embossing into one step and to perform in a common tool. Again, there is a plastic deformation of the shaft or transition region to form the crank or the offset.

In
Der Flachband-Weblitzenrohling 1 weist eine gerade Kante 9 auf, die sich von dem oberen Ende der oberen Endöse 7 bis zu dem unteren Ende der unteren Endöse 8 erstreckt. Diese gerade Kante 9 entspricht einer Seitenkante des ursprünglichen Metallbandabschnitts. Von der gegenüber liegenden geraden Kante sind jedoch lediglich noch zwei Abschnitte 10, 11 jeweils an den Endösen 2, 3 übrig. In einem dazwischen liegenden Abschnitt, der die Übergangsbereiche 5, 6 und den Schaft 4 beinhaltet, wurde Material von dem Metallbandabschnitt entfernt (z.B. in einem Stanz- oder Schneidevorgang), wodurch einwärts laufende Kantenabschnitte 12, 13 und ein nach innen versetzter Kantenabschnitt 14 entsteht. Der Schaft 4 ist außerdem mit einem Fadenauge 15 versehen worden, in dem eine entsprechende Öffnung an gewünschter Stelle eingebracht worden ist. Weitere Öffnungen 16, 17 können an den Endösen 2, 3 oder in den Übergangsbereichen 5, 6 vorgesehen werden.The flat-band heddle blank 1 has a
Werden die beiden Weblitzenrohlinge 1, 18 übereinander gelegt, ergibt sich das Bild nach
Die Weblitzenrohlinge 1, 18 durchlaufen deshalb einen weiteren Bearbeitungsschritt, z.B. einen Prägeschritt, im Verlaufe dessen sie z.B. in den Übergangsbereichen 5, 6 eine auswärts voneinander weg gerichtete Kröpfung erfahren. Dabei werden sie innerhalb der von den Endösen 2, 3 und dem Schaft 4 festgelegten Ebene so deformiert, dass das Fadenauge 15 auf einer gedachten Linie 19 liegt, wie die ehemalige Position der Kante 9 markiert. Diese gedachte Linie 19 verbindet verbleibende Abschnitte 9a, 9b der Kante 9, die an den Endösen 2, 3 noch vorhanden sind. Das Fadenauge 15 liegt mit seiner Mitte auf der Linie 19 oder ist über diese hinaus nach außen, d.h. in
Die so erzeugte Flachband-Weblitze 20 bedarf zu ihrer Herstellung im Vergleich zu herkömmlich aus einem entsprechend breiteren Metallbandabschnitt ausgestanzten Weblitzen eines geringeren Materialaufwands. Im Vergleich zu Weblitzen mit aufgeweiteten Endösen ergeben sich geringere lokale Materialverformungen. Die Materialwahl kann optimiert werden.The
Eine komplementäre Flachband-Weblitze 21 lässt sich aus dem Flachband-Weblitzenrohling 18 erzeugen. Wiederum wird ein Umformvorgang vorgenommen, in dessen Verlauf die Mitte des Schafts 4 auf die Linie 19 gebracht wird, die den ehemaligen Verlauf der Kante 9 markiert. Die Kante 9 wird dadurch in die Abschnitte 9a, 9b, 9c, 9d, 9e unterteilt. Die vorige Beschreibung des Flachband-Weblitzenrohlings 18 und der Flachband-Weblitze 20 gilt unter Zugrundelegung gleicher Bezugszeichen entsprechend.A complementary

Während der Versatz des Abschnitts 9c der Kante 9 bei allen vorigen Ausführungsbeispielen an den Übergangsabschnitten 5, 6 angeordnet ist, ist es auch möglich, diesen Versatz in den Bereich des Schafts 4 zu verlegen. Ein solches Beispiel zeigt
Die erfindungsgemäßen Weblitzen bestehen aus einem Metallbandabschnitt der Breite B, der schmaler ist als die insgesamt für die Flachbandlitze 20 benötigte Breite B+X. Die Flachbandlitze 20 weist eine im Wesentlichen unbearbeitete, jedenfalls unbeschnittene, von dem Metallbandabschnitt stammende Kante 9 und eine Kante 10, 11, 12, 13, 14 auf die im Bereich des Schafts 4 und der Übergangsabschnitte 5, 6 durch Beschneiden des Metallbandabschnitts erzeugt worden ist. Eine auswärts gerichtete Kröpfung des Schafts 4 schafft einen vergrößerten Abstand R zwischen zwei zusammengehörigen gegensinnig gekröpften Flachband-Weblitzen eines Weblitzenpaars 23, zu dem zwei gegensinnig gekröpfte Flachband-Weblitzen 20, 21 gehören.The healds according to the invention consist of a metal strip section of width B which is narrower than the total width B + X required for the flat stranded
