DE2000344 betrifft die Herstellung eines dicken Gewebes, wobei die einzelnen Gewebelagen miteinander verbunden sind. DE2000344 relates to the production of a thick fabric, whereby the individual fabric layers are connected to one another.

Nach dem Stand der Technik ist es nicht möglich, ein in Teilbereichen des Querschnittes mehrlagiges Rundgewebe in einem Rundwebevorgang herzustellen. Es ist allerdings aus PCT eine Vorrichtung bekannt, welche das Heben und Senken des Kettfadens beziehungsweise - unter Verwendung der im Folgenden gebrauchten Bezeichnungen - das Bringen des Kettfadens in eine erste Stellung und in eine zweite Stellung unabhängig von der Position und der Bewegung des Schussfadens oder des den Schussfaden führenden Webschiffes oder Webschützen erlaubt.According to the state of the art, it is not possible to produce a circular woven fabric with multiple layers in partial areas of the cross section in a circular weaving process. However, a device is known from PCT, which raises and lowers the warp thread or - using the terms used in the following - the bringing of the warp thread into a first position and into a second position is permitted regardless of the position and movement of the weft thread or the loom or shuttle guiding the weft thread.

Die hier offenbarte Erfindung stellt sich die Aufgabe, ein solches Verfahren zu offenbaren.The invention disclosed here has the object of disclosing such a method.

Erfindungsgemäß wird dies durch den Anspruch 1 erreicht.According to the invention, this is achieved by claim 1.

Zwei Fäden gelten als in einen Eingriff zueinander gebracht, wenn die Fäden im gespannten Zustand zueinander verkreuzt sind. Ein Schussfaden und zwei Kettfäden stehen in einem Eingriff, wenn der Schussfaden im gewobenen Zustand bei einen Kettfaden auf der einen Seite und beim anderen Kettfaden auf der anderen Seite geführt ist.Two threads are considered to be brought into engagement with one another if the threads are crossed with one another in the tensioned state. A weft thread and two warp threads are in engagement when the weft thread in the woven state is guided on one side of one warp thread and on the other side of the other warp thread.

Ein Faden wird an einem weiteren Faden vorbeigeführt, wenn der Faden und der weitere Faden nicht in Eingriff zueinander gebracht werden. Die Fäden werden nicht zueinander verkreuzt.A thread is fed past another thread when the thread and the further thread are not brought into engagement with one another. The threads are not crossed with each other.

Die Kettfäden des Rundgewebes können unterschiedliche Abstände zueinander aufweisen. Weiters kann die Oberfläche des Rundgewebes durch das Verweben der Kettfäden und des Schussfadens strukturiert sein.The warp threads of the circular fabric can have different distances from one another. Furthermore, the surface of the circular fabric can be structured by weaving the warp threads and the weft thread.

Das Verfahren kann auch in der Weise angewendet werden, dass ein mehrlagiges Rundgewebe hergestellt wird. Die Herstellung eines mehrlagigen Rundgewebes ist nicht Teil des erfindungsgemäßen Verfahrens. Der gesamte Querschnitt eines solchen Rundgewebes umfasst mehrere Gewebelagen. Dies wird dadurch erreicht, dass ein erster Schussfaden mit ersten Kettfäden in einer ersten Stellung in Eingriff gebracht wird und an zweiten Kettfäden in einer zweiten Stellung vorbeigeführt wird und ein zweiter Schussfaden an ersten Kettfäden in einer zweiten Stellung vorbeigebracht wird und an zweiten Kettfäden in einer ersten Stellung in Eingriff gebracht wird.The method can also be used in such a way that a multi-layer circular fabric is produced. The production of a multi-layer circular fabric is not part of the method according to the invention. The entire cross section of such a round fabric comprises several fabric layers. This is achieved in that a first weft thread is brought into engagement with first warp threads in a first position and on second warp threads is guided past in a second position and a second weft thread is brought past first warp threads in a second position and is brought into engagement with second warp threads in a first position.

Der Fachmann ist in der Lage das oben beschriebene Verfahren zur Herstellung eines in einem Teilbereich des Querschnittes mehrlagiges Rundgewebe mit dem erwähnten Verfahren zur Herstellung eines mehrlagigen Rundgewebes zu kombinieren.The person skilled in the art is able to combine the above-described method for producing a multi-layer circular fabric in a partial area of the cross-section with the mentioned method for producing a multi-layer circular fabric.

Zum besseren Verständnis der Erfindung wird diese anhand der nachfolgenden Figuren näher erläutert. Der Fachmann wählt die Führung der Schussfäden nach seiner Erfahrung.

  • Figur 1 zeigt in stark vereinfachter Darstellung ein Schnittbild eines Querschnittes eines Rundgewebes mit einem in Teilbereichen des Querschnittes mehrlagigen Aufbau.
  • Figur 2 zeigt in ebenso stark vereinfachter Darstellung ein Schnittbild eines Querschnittes eines Rundgewebes mit einem über den gesamten Querschnitt sich erstreckenden mehrlagigen Aufbau.
For a better understanding of the invention, it is explained in more detail with reference to the following figures. The expert selects the guidance of the weft threads according to his experience.
  • Figure 1 shows in a greatly simplified representation a sectional view of a cross section of a circular fabric with a multi-layer structure in partial areas of the cross section.
  • Figure 2 shows, in an equally simplified representation, a sectional view of a cross section of a circular fabric with a multilayer structure extending over the entire cross section.

Der Fachmann ist zweifelsfrei in der Lage, die im Folgenden diskutierten Ausführungsformen des erfindungsgemäßen Verfahrens miteinander zu kombinieren, sodass ein Schlauch Teillängen mit einem in Teilbereichen mehrlagig ausgeführten Querschnitt und weitere Teillängen mit einem mehrlagig ausgebildeten gesamten Querschnitt umfasst.The person skilled in the art is undoubtedly in a position to combine the embodiments of the method according to the invention discussed below so that a hose comprises partial lengths with a multi-layered cross section in partial areas and further partial lengths with a multi-layered overall cross section.

In den Figuren 1, 2 und in der dazugehörenden Figurenbeschreibung wird die Herstellung eines Rundgewebes mit zumindest in Teilbereichen des Querschnittes zwei Gewebelagen diskutiert. Der Fachmann ist zweifelsfrei in der Lage auch dreilagige oder mehrlagige Querschnitte herzustellen und diese beliebig miteinander zu kombinieren.In the Figures 1, 2 and in the associated description of the figures, the production of a round fabric with two fabric layers at least in partial areas of the cross-section is discussed. The person skilled in the art is undoubtedly able to produce three-layer or multi-layer cross-sections and combine these with one another as desired.

Figur 1 veranschaulicht die Herstellung eines in Teilbereichen des Querschnittes zweilagigen Rundgewebes 1 anhand eines Schnittbildes des Querschnittes. Die Schnittebene verläuft rechtwinkelig zu der Längsachse 7 des Rundgewebes 1. Das in Figur 1 durch eine gestrichelte Linie vereinfacht dargestellte Rundgewebe 1 umfasst einen einlagigen Teilbereich 19 und einen zweilagigen Teilbereich 20, wobei der einlagige Teilbereich 19 an den zweilagigen Teilbereich 20 und umgekehrt direkt anschließt. In Figur 1 sind nur im zweilagigen Teilbereich 20 der Schussfaden 2 und die Kettfäden 11-18 dargestellt. Figure 1 illustrates the production of a two-ply circular fabric 1 in partial areas of the cross-section on the basis of a sectional image of the cross-section. The cutting plane runs at right angles to the longitudinal axis 7 of the circular fabric 1. The in Figure 1 Round fabric 1, shown simplified by a dashed line, comprises a single-layer partial area 19 and a two-layer sub-area 20, the single-layer sub-area 19 directly adjoining the two-layer sub-area 20 and vice versa. In Figure 1 the weft thread 2 and the warp threads 11-18 are shown only in the two-layer sub-area 20.

Das in Figur 1 dargestellte Rundgewebe 1 wird in einem Arbeitsschritt mittels Rundwebeverfahren hergestellt. Das Rundgewebe 1 umfasst einen Schussfaden 2 und acht Kettfäden 11, 12, 13, 14, 15, 16, 17, 18. Der Schussfaden 2 wird in vier Rundgängen 3, 4, 5, 6 um eine Längsachse 7 des Rundgewebes 1 geführt und mit den Kettfäden 11-18 verwoben.This in Figure 1 Round fabric 1 shown is produced in one work step by means of a circular weaving process. The circular fabric 1 comprises a weft thread 2 and eight warp threads 11, 12, 13, 14, 15, 16, 17, 18. The weft thread 2 is guided in four rounds 3, 4, 5, 6 around a longitudinal axis 7 of the circular fabric 1 and with woven into warp threads 11-18.

Die Kettfäden 11-18 sind unter Verweis auf PCT/EP2016/069685 entkoppelt von einer Bewegung des Schussfadens 1 zwischen einer ersten Stellung und einer zweiten Stellung bewegbar. In der ersten Stellung eines Kettfadens 11-18 ist der Schussfaden 1 mit dem einen Kettfaden in Eingriff bringbar. In der zweiten Stellung wird der Schussfaden 1 an dem einem Kettfaden vorbeigeführt, sodass der Schussfaden mit dem einen Kettfaden nicht in Eingriff gebracht wird.The warp threads 11-18 are referencing PCT / EP2016 / 069685 decoupled from a movement of the weft thread 1 between a first position and a second position. In the first position of a warp thread 11-18, the weft thread 1 can be brought into engagement with the one warp thread. In the second position, the weft thread 1 is guided past the one warp thread so that the weft thread is not brought into engagement with the one warp thread.

Bei dem in Figur 1 dargestellten Ausführungsbeispiel wird die erste Stellung eines Kettfadens und die zweite Stellung eines Kettfadens durch ein System von Heben A und Senken B des jeweiligen Kettfadens erreicht.The in Figure 1 illustrated embodiment, the first position of a warp thread and the second position of a warp thread is achieved by a system of raising A and lowering B of the respective warp thread.

Zur Herstellung des in einem Teilbereich des Querschnittes zweilagigen Rundgewebes 1 werden die Kettfäden 11, 13, 15, 17 der ersten Gewebelage 8 zugewiesen. Die Kettfäden 12, 14, 16, 18 werden der zweiten Gewebelage 9 zugewiesen. In der nachstehenden Tabelle ist für die einzelnen Kettfäden 11-18 in Abhängigkeit des Rundganges 3-6 des Schussfadens 2 eingetragen, ob der jeweilige Kettfaden aus der Gruppe der Kettfäden 11-18 in eine gehobene Stellung oder in eine gesenkte Stellung zu bringen ist.In order to produce the two-ply circular fabric 1 in a partial area of the cross-section, the warp threads 11, 13, 15, 17 are assigned to the first fabric ply 8. The warp threads 12, 14, 16, 18 are assigned to the second fabric layer 9. In the table below it is entered for the individual warp threads 11-18, depending on the tour 3-6 of the weft thread 2, whether the respective warp thread from the group of warp threads 11-18 is to be brought into a raised position or into a lowered position.

Nach der in der nachstehenden Tabelle ersichtlichen Webmuster werden der Schussfaden 1 im ersten Rundgang 3 mit den Kettfäden 13, 17 im Eingriff verwoben. Beim Führen des Schussfadens 2 im ersten Rundgang 3 sind die Kettfäden 11, 12, 14, 15, 16, 18 in einer gehobenen Stellung A. Die Kettfäden 13, 17 sind in einer gesenkten Stellung B. Die Stellungen der Kettfäden 11-18 beim zweiten Durchgang 4, dritten Durchgang 5 und vierten Durchgang 6 des Schussfadens 2 sind der unten-stehenden Tabelle 1 zu entnehmen.According to the weaving pattern shown in the table below, the weft thread 1 is interwoven with the warp threads 13, 17 in the first round 3. When guiding the weft thread 2 in the first tour 3, the warp threads 11, 12, 14, 15, 16, 18 are in a raised position A. The warp threads 13, 17 are in a lowered position B. The positions of the warp threads 11-18 in the second Passage 4, third passage 5 and fourth passage 6 of the weft thread 2 can be found in Table 1 below.

Der einlagige Teilbereich 19 des Querschnittes wird durch Verweben des Schussfadens mit den Kettfaden nach dem Stand der Technik hergestellt.

Das in Figur 2 gezeigte Verfahren ist nicht Teil der Erfindung. Figur 2 zeigt ein Rundgewebe 1 und ein weiteres Rundgewebe 1', wobei das weitere Rundgewebe 1' im Inneren des Rundgewebes 1 angeordnet ist. Figure 2 illustrates the use of the method for producing a circular fabric in one process step, which circular fabric comprises a two-layer structure over the entire cross section. This in Figure 2 The method shown does not form part of the invention. Figure 2 shows a circular fabric 1 and a further circular fabric 1 ′, the further circular fabric 1 ′ being arranged in the interior of the circular fabric 1.

Das Verfahren zur Herstellung eines mehrlagigen Rundgewebes 1, 1' läuft im Wesentlichen ähnlich zu dem zu Figur 1 diskutierten Verfahren ab.The method for producing a multi-layer round fabric 1, 1 'is essentially similar to that Figure 1 discussed procedures.

Das Rundgewebe 1, 1' umfasst zwei Schussfaden 2, 2', wobei durch den ersten Schussfaden 2 die erste Gewebelage 8 und durch den zweiten Schussfaden 2' die zweite Gewebelage 9 ausgebildet wird. Es ist die Verwendung von zumindest zwei Schussfäden notwendig, um einen Verbund zwischen den Rundgeweben 1, 1' zu vermeiden.The circular fabric 1, 1 'comprises two weft threads 2, 2', the first fabric layer 8 being formed by the first weft thread 2 and the second fabric layer 9 being formed by the second weft thread 2 '. It is necessary to use at least two weft threads in order to avoid a bond between the circular fabrics 1, 1 '.

Es werden die Kettfäden 11, 13, 15, 17 der ersten Gewebelage 8 zugeordnet. Die Kettfäden 12, 14, 16, 18 werden der zweiten Gewebelage 9 zugeordnet. Beim Verwenden der Schussfäden 2, 2' werden die Kettfäden 11-18 gemäß der folgenden Tabelle in eine gehobene Stellung A oder in eine gesenkte Stellung B gebracht, um einen Eingriff zwischen dem jeweiligen Schussfaden und dem jeweiligen Kettfaden herzustellen.The warp threads 11, 13, 15, 17 are assigned to the first fabric layer 8.

  • Weft thread 2 first round 3, weft thread 2 'third round 5, weft thread 2 second round 4, weft thread 2' fourth round 6.

Figur 3 veranschaulicht den Übergang von einem zweilagigen Teilbereich 20 des Querschnittes zu einem einlagigen Teilbereich 19 des Querschnittes. Ähnlich wie das in Figur 1 diskutierte Rundgewebe umfasst das Rundgewebe einen Schussfaden 2 und Kettfäden 11-14 und 21-22, wobei der zweilagige Teilbereich 20 des Rundgewebes 1 durch die Kettfäden 11-14 erreicht wird. Der einlagige Teilbereich 19 wird durch die Kettfäden 21, 22 erreicht. Figure 3 illustrates the transition from a two-layer partial area 20 of the cross section to a single-layer partial area 19 of the cross section. Similar to the one in Figure 1 The circular fabric discussed here comprises a weft thread 2 and warp threads 11-14 and 21-22, the two-layer sub-area 20 of the circular fabric 1 being reached by the warp threads 11-14. The single-layer sub-area 19 is reached by the warp threads 21, 22.

Die Kettfäden 11, 13 sind der ersten Gewebelage 8 und die Kettfäden 12, 14 sind der zweiten Gewebelage 9 zugewiesen. Der Schussfaden 1 wird in einer ersten Rundung 3 und in einer zweiten Rundung 4 durch die Kettfäden 11-14, 21-22 geführt, wobei die Kettfäden gemäß der untenstehenden Tabelle in eine gehobene Lage A oder eine gesenkte Lage B gebracht werden.

  1. A method for preparing a circular woven fabric (1, 1') comprising a plurality of fabric layers (8, 9) in a subregion of its cross-section that comprises at least one weft (2) and a plurality of warps (10-18),
    which weft (2) is guided around a longitudinal axis (7) of the circular woven fabric (1, 1') in circuits (3, 4),
    which warps (11-18), decoupled from a movement of the weft (2, 2'), are moved between a first position and a second position,
    in which first position the warp (11-18) is engaged with the weft (2, 2'), and
    in which second position the weft (2, 2') is guided past the warp (11-18),
    wherein a number of first warps (11, 13, 15, 17) are assigned to a first fabric layer (8) and a number of second warps (12, 14, 16, 18) are assigned to a second fabric layer (9), wherein,
    at the first circulation (3), the weft (2) is engaged with the first warps (11, 13, 15, 17) in the first position and guided past the second warps (12, 14, 16, 18) in the second position, and
    at the second circulation (4), the weft (2) is guided past the first warps (11, 13, 15, 17) in the second position and engaged with the second warps (12, 14, 16, 18) in the first position.
