Description

Die Erfindung betrifft ein Verfahren zum Herstellen von als Doppelstück gewebten Teppichen, bei dem die Figuren von sog. Polkettfäden gebildet werden, welche von dem Obergewebe zu dem Untergewebe und umgekehrt laufen und in dem Augenblick, in dem die Polfäden von dem einen Gewebe zu dem anderen laufen, als arbeitender oder figurenbildender Pol (musterbildender Pol) unterschieden werden, während die nicht arbeitenden Polfäden als toter Pol (tote Chore) bezeichnet werden.The invention relates to a method for producing carpets woven as a double piece, in which the figures are formed by so-called pile warp threads which run from the upper fabric to the lower fabric and vice versa and at the moment when the pile threads move from one fabric to the other run as a working or figure-forming pole (pattern-forming pole), while the non-working pile threads are called dead pole (dead chore).

Ferner betrifft die Erfindung insbesondere ein Verfahren zum Weben auf einem Einzel- oder Doppelgreiferwebstuhl unter Ausschaltung des Einschusses eines Doppelstückgewebes (abwechselnd je ein Schuß ins Ober- und Unterfach) infolge der einspuligen Bindung (bzw. mit Einzelfach-Schußeintrag).Furthermore, the invention relates in particular to a method for weaving on a single or double rapier loom with the exclusion of the weft of a double piece fabric (alternately one weft in the upper and lower compartment) as a result of the single-spool binding (or with single-compartment weft insertion).

Der Stand der Technik wird an Hand der hier beigefügten Figur 1 veranschaulicht, die schematisch eine einspulige Bindung (bzw. Einschuß-Bindung) eines Doppelstückgewebes darstellt. Zum Weben eines Doppelstück-Teppichgewebes nach dem einspuligen Webprinzip wird ein Schußfaden (1) abwechselnd in das Untergewebe (OW) und das Obergewebe (BW) eingebracht. Bei dem ersten Schuß befindet sich der Schußfaden (1) unter dem Spannkettfaden (SO) des Untergewebes (OW). Bei dem nächsten Schuß befindet sich der Schußfaden (1) oberhalb des Spannkettfadens (SB) des Obergewebes. Bei dem nachfolgenden Schuß befindet sich der Schußfaden (1) oberhalb des Spannkettfadens (SO) des Untergewebes (OW). Bei dem darauffolgenden Schuß befindet sich der Schußfaden (1) unter dem Spannkettfaden (SB) des Obergewebes (BW).The state of the art is illustrated by the attached Figure 1 illustrates, which schematically represents a single-coil weave (or weft weave) of a double piece fabric. To weave a double-piece carpet fabric according to the single-spool weaving principle, a weft thread (1) is inserted alternately into the lower fabric (OW) and the upper fabric (BW). In the first weft, the weft thread (1) is located under the tension warp thread (SO) of the lower fabric (OW). On the next weft, the weft thread (1) is located above the tension warp thread (SB) of the upper fabric. In the following weft, the weft thread (1) is located above the tension warp thread (SO) of the lower fabric (OW). In the subsequent weft, the weft thread (1) is located under the tension warp thread (SB) of the upper fabric (BW).

Um den Schußfaden (1) an die Spannkettfäden SO und SB zu binden, werden ein oder mehrere Bindkettfäden BO und BB hinzugesetzt.To bind the weft thread (1) to the tension warp threads SO and SB, one or more binding warp threads BO and BB are added.

Es gibt verschiedene bekannte Arbeitsweisen, um diese Bindkettfäden anzubinden. Die Grundbindung wiederholt sich je 4 Schuß, wie es im Beispiel der Figur 1 der Fall ist - wenn sich die Grundbindung bei dem Schuß 1-2-3-4, 5-6-7-8, 9-10-11-12 usw. wiederholt. Zum Numerieren jedes Schusses geht man von dem am weitesten links liegenden Schuß aus - der aus einem in das Unter gewebe OW eingebrachten Schußfaden (I) besteht - der als Schuß 1 bezeichnet wird, während man beim Durchgang durch das Gewebe von links nach rechts die aufeinanderfolgenden Schußfäden in der Reihenfolge: Schuß 2, Schuß 3 usw. benennt. In der Figur ist die Numerierung vertikal unterhalb jedes Schusses angezeigt. Die Polkettfäden sind mit P1, P2, P3, P4 und P5 angegeben.There are various known ways of tying these binding warp threads. The basic binding repeats 4 shots each, as is the case in the example in FIG. 1 - if the basic binding changes in the weft 1-2-3-4, 5-6-7-8, 9-10-11-12, etc . repeated. To number each shot one starts from the left-most weft - which consists of a weft thread (I) inserted into the lower fabric OW - which is referred to as weft 1, while one passes through the fabric from left to right the successive Weft threads in the order: weft 2, weft 3, etc. In the figure, the numbering is shown vertically below each shot. The pile warp threads are indicated with P1, P2, P3, P4 and P5.

Hinsichtlich des Greifers oder des Einschusses können diese Polkettfäden zwei Stellungen einnehmen.With regard to the gripper or the weft, these pile warp threads can take two positions.

Wenn der Polkettfaden zwischen dem Untergewebe (OW) und dem Obergewebe (BW) keine Verbindung herstellt, das heißt, als toter Pol erscheint, beteiligt sich dieser Polkettfaden an der Bindung des Untergewebes OW bzw. des Obergewebes BW, so daß man von einem eingebundenen Polkettfaden oder kurz von einem eingebundenen, toten Pol spricht.If the pile warp thread does not make a connection between the lower fabric (OW) and the upper fabric (BW), i.e. it appears as a dead pile, this pile warp thread participates in the binding of the lower fabric OW or the Upper fabric BW, so that one speaks of an integrated pile warp thread or briefly of an integrated, dead pile.

Gemäß dem Stand der Technik erfolgt die Wahl zwischen dem Verbleib als eingebundener Polkettfaden oder als arbeitender oder Figuren formender Polkettfaden für eine Verbindung z.B. der beiden Gewebe OW und BW bzw. BW und OW nach dem Schuß 2. Wenn ein Polkettfaden - beispielsweise P1 - als arbeitender Pol beim Schuß 1 wirksam ist, wird dieser Faden P1 unter den Schußfaden gebracht, während die anderen Polkettfäden über den Schußfaden geführt werden. Bei dem Schuß 2 wird der Polkettfaden P1 über den Schußfaden gelegt werden, während die anderen Polkettfäden unter den Schußfaden gebracht werden. Nach dem Schuß 2 soll ein Farbenwechsel geschehen mit dem Polkettfaden P2, der im Unterteil (Untergewebe) eingebunden ist. Bei dem Schuß 3 wird dann der arbeitende Polkettfaden P2 zusammen mit den eingebundenen Polkettfäden des Unterteppichs (zu denen auch der Polkettfaden P1 gehört) erst unter den Schußfaden geführt. Beim Schuß 3 sind die im Oberteppich eingebundenen Polkettfäden oben. Beim Schuß 4 ist nun der Polkettfaden P2 zusammen mit den im Oberteil eingebundenen Polkettfäden (Farben) über dem Schuß I. Im Unterteil eingebundene Farben sind unten. Nach dieser Technik erhält man die einspulige Bindung.According to the prior art, the choice is between remaining as an integrated pile warp thread or as a working or figure-forming pile warp thread for a connection e.g. of the two fabrics OW and BW or BW and OW after the weft 2. If a pile warp thread - for example P1 - is effective as a working pile in weft 1, this thread P1 is brought under the weft thread, while the other pile warp threads are passed over the weft thread . In the weft 2, the pile warp thread P1 will be placed over the weft thread, while the other pile warp threads are brought under the weft thread. After the weft 2, a change of color should take place with the pile warp thread P2, which is integrated in the lower part (lower fabric). In the weft 3, the working pile warp thread P2 is then only guided under the weft thread together with the integrated pile warp threads of the sub-carpet (which also includes the pile warp thread P1). At weft 3, the pile warp threads integrated in the top carpet are at the top. In weft 4, the pile warp thread P2 is now together with the pile warp threads (colors) integrated in the upper part above the weft I. The colors integrated in the lower part are below. The single-coil binding is obtained using this technique.

Diese einspulige Bindung hat den Nachteil, daß sie sog. Doppeltverarbeitungen ("Doppelarbeiter") zeigt. Bei dem Übergang von einer bestimmten Farbe, die von einem Figuren bildenden Polkettfaden gebildet wird, der nach jenem Übergang z.B. in dem Obergewebe eingebunden wird, zu einer anderen Farbe, die von einem figurenbildenden Polkettfaden gebildet wird, der vor jenem Übergang im gegenüberliegenden Gewebe (Untergewebe) eingebunden war, läuft ein Stückchen der endenden Farbe mit der beginnenden Farbe zusammen (siehe Schüsse 15 und 16 der Figur 1). Diese beiden Polfadenstückchen unterschiedlicher Farbe werden sich (in Schußrichtung) beieinanderlegen und werden Doppelarbeiter genannt. Die Trennlinie zwischen diesen beiden Farbfeldern ist undeutlich und zeigt eine gewisse Verzahnung.This single-coil binding has the disadvantage that it shows so-called double processing ("double workers"). In the transition from a certain color, which is formed by a figure-forming pile warp thread, which is incorporated after the transition, e.g. in the upper fabric, to another color, which is formed by a figure-forming pile warp thread, which occurs before that transition in the opposite fabric (lower fabric ) was involved, a piece of the ending color runs together with the beginning color (see shots 15 and 16 of FIG. 1). These two pieces of pile thread of different colors will lay together (in the weft direction) and will Called double workers. The dividing line between these two color fields is indistinct and shows some interlocking.

In Fig. 2 der europäischen Patentschrift Nr. 175.963 ist eine Doppelplüschgewebebindung ohne Doppelarbeiter dargestellt. Eine der beiden Polschleifen, die ansonsten den Doppelarbeiter bilden, ist weggelassen. Herkömmlicherweise sieht man auf der Kartenzeichnung für 4 Schuß (2 Schuß je Teppich) einen Farbpunkt vor, entsprechend dem Rapport der Grundbindung von 4 Schuß.In Fig. 2 of European Patent No. 175,963 a double plush weave is shown without a double worker. One of the two pole loops, which otherwise form the double worker, has been left out. Conventionally, a color point is provided on the card drawing for 4 shots (2 shots per carpet), corresponding to the repeat of the basic weave of 4 shots.

Für eine Musterungsfeinheit von z.B. 4 Löchern/cm in der Kartenzeichnung muß man 8 Schuß/cm in dem Teppich vorsehen.For a pattern fineness of e.g. 4 holes / cm in the map drawing you have to provide 8 shots / cm in the carpet.

Der Gegenstand der Erfindung ist eine Arbeitsweise zum Weben eines Doppelstück-Polgewebes, ferner insbesondere einer Einschußbindung gemäß einem einzel oder doppelspuligen Webverfahren unter Ausschaltung eines Einschusses mit dem Ziel, Doppelarbeiter auszuschließen, kombiniert mit einer Musterungsfeinheit von 1,5 Schuß je Teppich und Farbpunkt in der Kartenzeichnung.The object of the invention is a method of weaving a double-piece pile fabric, furthermore in particular a weft weave according to a single or double-spool weaving process with elimination of a weft with the aim of excluding double workers, combined with a pattern fineness of 1.5 weft per carpet and color point in the Map drawing.

Die Arbeitsweise zum Herstellen eines Doppelstück-Teppichgewebes, insbesondere in einer einspuligen Bindung, besteht ferner darin, den Arbeitsrapport für die Polkettfäden auf 3 Schuß (1,5 Schuß je Teppich) zu legen, während der Arbeitsrapport der Grundbindung sich über 4 Schuß (2 Schuß je Teppich) erstreckt.The procedure for producing a double-piece carpet fabric, in particular in a single-coil weave, is further to place the working repeat for the pile warp threads on 3 wefts (1.5 wefts per carpet), while the working repeat of the basic weave is over 4 wefts (2 wefts extends per carpet).

Bei dem Schuß 2, 6, 10, 14,... befindet sich der Einschuß (102, 106, I010,...)oberhalb des Spannkettfadens (S0), während sich bei dem Schuß (4, 8, 12,...) der Einschuß (104, 108, I012,...) unter dem Spannkettfaden befindet.With each even-numbered weft (2, 4, 6, ...) the weft (102, 104, ...) is in the lower fabric. With weft 2, 6, 10, 14, ... the weft (102, 106, I010, ...) is above the tension warp thread (S0), while with the weft (4, 8, 12, .. .) the weft (104, 108, I012, ...) is located under the tension warp thread.

Die Art und Weise, in der diese Einschüsse mit Hilfe der Bindkettfäden angebunden werden, ist bekannt und erfolgt bei einem Rapport von 4 Schuß.The way in which these wefts are tied with the help of the binding warp threads is known and takes place with a repeat of 4 wefts.

Andererseits wird bei der Arbeitsweise gemäß der Erfindung für die Polkettfäden ein Arbeitsrapport von 3 Schuß (1,5 Schuß je Teppich) aufgestellt: dieser Arbeitsrapport wird im einzelnen für die Figuren bildenden Polkettfäden (PF), für die in dem Obergewebe eingebundenen Polkettfäden (PIBW) und für die in dem Untergewebe eingebundenen Polkettfäden (PIOW) aufgeführt.On the other hand, when working in accordance with the invention, a working repeat of 3 wefts (1.5 wefts per carpet) is set up for the pile warp threads: this work repeat is described in detail for the pile warp threads (PF) forming the figures, for the pile warp threads (PIBW) incorporated in the upper fabric. and for the pile warp threads (PIOW) embedded in the lower fabric.

Im Falle eines solchen,drei Chore enthaltenden Gewebes, wie es in Figur 3a dargestellt ist, bildet der Polkettfaden (P1) bei dem Schuß (1, 2, 3) die Figuren und ist bei dem Schuß (4, 5, 6), (7, 8, 9),... in dem Obergewebe eingebunden; der Polkettfaden (P2) ist bei dem Schuß (1, 2, 3) in dem Untergewebe eingebunden, bildet beim Schuß (4, 5, 6) Figuren und ist beim Schuß (7, 8, 9, 10, 11, 12,...) wieder in dem Untergewebe eingebunden; der Polkettfaden (P3) ist bei dem Schuß (1, 2, 3) und (4, 5, 6) in dem Untergewebe eingebunden, bildet bei dem Schuß (7, 8, 9) Figuren und ist bei dem Schuß (10, 11, 12) wieder in dem Untergewebe eingebunden. Auf der Kartenzeichnung erhält man einen Farbpunkt je 3 Schuß insgesamt oder je 1,5 Schuß in dem Teppich, während sich der Arbeitsrapport für die Polkettfäden über 3 Schuß erstreckt, wobei Rapporte A, B, C und D für eine Anbindung in der Grundbindung hintereinanderliegen und diese Rapporte sich voneinander in der Reihenfolge der Schüsse dadurch unterscheiden, daß die Schußfäden oberhalb (B) oder unterhalb (O)der Spannkettfäden des Obergewebes (BW) oder des Untergewebes (OW) in der folgenden Art und Weise verlaufen.

  • Bei dem Rapport A hat man B/BW - B/OW - O/BW,
  • bei dem Rapport B hat man O/OW - B/BW - B/OW,
  • bei dem Rapport C hat man O/BW - O/OW - B/BW und
  • bei dem Rapport D hat man B/OW - O/BW - O/OW.
In the case of such a fabric containing three choirs, as shown in FIG. 3a, the pile warp thread (P1) forms the figures in the weft (1, 2, 3) and is in the weft (4, 5, 6), ( 7, 8, 9), ... embedded in the upper fabric; the pile warp thread (P2) is in the weft (1, 2, 3) in the lower fabric incorporated, forms figures when weft (4, 5, 6) and is again integrated into the lower fabric when weft (7, 8, 9, 10, 11, 12, ...); the pile warp thread (P3) is bound in the weft (1, 2, 3) and (4, 5, 6) in the lower fabric, forms figures in the weft (7, 8, 9) and is in the weft (10, 11 , 12) again integrated in the lower fabric. On the map drawing you get a color point for 3 wefts in total or 1.5 wefts in the carpet, while the working repeat for the pile warp threads extends over 3 wefts, with repeats A, B, C and D for a connection in the basic weave and these reports differ from one another in the order of the wefts in that the weft threads above (B) or below (O) the tension warp threads of the upper fabric (BW) or the lower fabric (OW) run in the following manner.
  • Repeat A has B / BW - B / OW - O / BW,
  • Repeat B has O / OW - B / BW - B / OW,
  • Repeat C has O / BW - O / OW - B / BW and
  • Repeat D has B / OW - O / BW - O / OW.

Die von den Polkettfäden in einem bestimmten Arbeitsrapport einzunehmende Position ist von der Stellung der Polkettfäden während des vorherigen Rapportes entweder in einem Figuren bildenden Pol oder in einer eingebundenen Lage oder in dem Arbeitsrapport A, B, C oder D abhängig.The position to be occupied by the pile warp threads in a specific work report depends on the position of the pile warp threads during the previous repeat either in a figure-forming pole or in an integrated position or in the work report A, B, C or D.

Die verschiedenen Möglichkeiten sind in Figur 4 zusammengestellt. Diese Tabelle, in der die folgenden Abkürzungen benutzt werden, kann für die Auswahl des passenden Manchons verwendet werden:

Entsprechend der erwünschten Arbeitsweise werden in Figur 5 die anzuwendenden Bindungsmanchons gemeinsam mit den jeweiligen Positionen der Kettfäden angegeben.In accordance with the desired mode of operation, the binding manchons to be used are indicated in FIG. 5 together with the respective positions of the warp threads.

Bei allen zwei Schuß der Grundbindung (ein Schuß je Teppich) wird eine Polschleife mit mindestens einem Bein auf dem Unteraewebe (OW) gleichwohl wie auf dem Obergewebe (BW) gebildet. Nur fehlt eine Polschleife eines Figuren bildenden Polkettfadens (siehe Schuß 3, 4 und Schuß 10, 11 in Figur 3a) in dem Übergang eines Figuren bildenden Pols, der in dem Oberteil eingebunden wird, während der neue,Figuren bildende Pol hierfür in dem Unterteil eingebunden war, und auch im Übergang eines Figuren bildenden Pols, der im Unterteil eingebunden wird, während der neue, Figuren bildende Pol dafür in dem Oberteil eingebunden war, und dies gilt für alle Arbeitsrapporte A, B, C und D.With all two wefts of the basic weave (one weft per carpet), a pile loop with at least one leg is formed on the lower fabric (OW) as well as on the upper fabric (BW). Only one pole loop of a figure-forming pile warp thread (see weft 3, 4 and weft 10, 11 in FIG. 3a) is missing in the transition of a figure-forming pole, which is integrated in the upper part, while the new figure-forming pole is integrated in the lower part was, and also in the transition of a figure-forming pole, which is integrated in the lower part, while the new figure-forming pole for it was incorporated in the top, and this applies to all work reports A, B, C and D.

Wie in Figur 3a dargestellt ist, hat man bei dem Verfahren gemäß der Erfindung innerhalb der Bindung folgende Verhältnisse:As shown in FIG. 3a, the following relationships are present within the binding in the method according to the invention:

Bei dem Schuß (1, 2, 3) ist der figurenbildende Polkettfaden (P1) zur Einbindung in dem Obergewebe (BW) vorgesehen , wobei der vorherige Arbeitsrapport keine Figuren bildete (also Leinwand war) und nun der Arbeitsrapport A und somit der Manchon (21) angewendet werden sollen (siehe die Tabelle der Figur 4).In the weft (1, 2, 3) the figure-forming pile warp thread (P1) is provided for integration in the upper fabric (BW), the previous work report not forming any figures (i.e. it was a canvas) and now the work report A and thus the manchon (21 ) are to be used (see the table in FIG. 4).

Bai dem Schuß (4, 5, 6) ist der Figuren bildende Polkettfaden (P2) zum Einbinden in dem Untergewebe (OW) vorgesehen. Der vorherige Rapport bildete einen Pol aber eines anderen Polkettfadens, der zu seiner Einbindung in dem Oberteil vorgesehen war, und das geschieht an dem Arbeitsrapport B. Dann muß der Manchon (18) benutzt werden (siehe Figur 4). Es gibt keinen Doppelarbeiter zwischen dem Schuß 2 und 3.Bai the weft (4, 5, 6) of the figure-forming pile warp thread (P2) is provided for binding in the lower fabric (OW). The previous repeat formed a pile but a different pile warp thread, which was intended for its integration in the upper part, and this is done on the work repeat B. Then the manchon (18) must be used (see FIG. 4). There is no double worker between shot 2 and 3.

Bei dem Schuß (7, 8, 9) ist der Figuren bildende Polkettfaden (P3) zum Einbinden in dem Unterteil vorgesehen, während der vorherige Rapport einen Pol aber eines anderen Polkettfadens bildete, der zum Einbinden in dem Unterteil nunmehr in dem Arbeitsrapport C vorgesehen war, für den dann der Manchon (15) angewendet werden soll (siehe Figur 4).In the weft (7, 8, 9) the figure-forming pile warp thread (P3) is provided for binding in the lower part, while the previous repeat formed a pile but a different pile warp thread, which was now intended for binding in the lower part in the work repeat C. , for which the manchon (15) is then to be used (see FIG. 4).

Bei dem Schuß (10, 11, 12) ist der Figuren bildende Polkettfaden (P1) zum Einbinden in dem Obergewebe vorgesehen, während der vorherige Arbeitsrapport ebenfalls Figuren mit einem anderen Polfaden bildete, der zum Einbinden in dem Untergewebe nunmehr auch in dem Arbeitsrapport D vorgesehen ist, für den der Manchon (32) benutzt werden soll (siehe Figur 4).In the weft (10, 11, 12), the figure-forming pile warp thread (P1) is provided for binding in the upper fabric, while the previous work repeat also formed figures with another pile thread, which is now also provided in the work repeat D for binding in the lower fabric for which the manchon (32) is to be used (see FIG. 4).

Bei dem Schuß (13, 14, 15) ist der Figuren bildende Polfaden (P1) zum Einbinden in dem Obergewebe vorgesehen, während der vorherige Arbeitsrapport auch Figuren mit demselben Polfaden nunmehr wieder in dem Arbeitsrapport A bildete, so daß der Manchon 25 gebraucht werden soll (siehe Figur 4).In the weft (13, 14, 15), the figure-forming pile thread (P1) is provided for binding in the upper fabric, while the previous work report now also formed figures with the same pile thread in the work report A, so that the sleeve 25 is to be used (see Figure 4).

In der hier beigefügten Figur 5 werden die verschiedenen Stellungen für die unterschiedlichen Kettfäden für jeden Manchon in Form von Tabellen aufgeführt.In FIG. 5 attached here, the different positions for the different warp threads for each manchon are listed in the form of tables.

Für die Bindung der Figur 3a benötigt man also nacheinander die Manchons 21, 18, 15, 32 und 25. Beim Ablesen der Tabelle nach Figur 5 ergeben sich z. B. für den Figuren bildenden Polkettfaden nacheinander die Stellungen: oben - unten - oben/unten - oben - unten/oben - unten - oben/oben - oben - unten/oben - unten - oben. Dies stimmt in der Tat mit den aufeinanderfolgenden Stellungen des Polkettfadens (P1) (für den Schuß 1, 2, 3), des Polkettfadens (P2) (für den Schuß 4, 5, 6), des Polkettfadens (P3) (für den Schuß 7, 8, 9) und des Polkettfadens (P1) (für den Schuß 10, 11, 12, 13, 14, 15) überein, wie die schematische Wiedergabe der gewünschten Bindung in Figur 3a zeigt.For the binding of FIG. 3a, the manchons 21, 18, 15, 32 and 25 are required one after the other. B. for the figure-forming pile warp thread one after the other the positions: top - bottom - top / bottom - top - bottom / top - bottom - top / top - top - bottom / top - bottom - top. This is indeed true of the successive positions of the pile warp thread (P1) (for weft 1, 2, 3), the pile warp thread (P2) (for the weft 4, 5, 6), the pile warp thread (P3) (for the weft 7, 8, 9) and the pile warp thread (P1) (for the weft 10, 11, 12, 13, 14, 15 ), as the schematic representation of the desired binding in Figure 3a shows.

Aus Figur 5 lassen sich auf dieselbe Art ebenfalls die Stellungen der anderen Polkettfäden ablesen, die mit den verschiedenen Manchons übereinstimmen. Die anderen möglichen Polkettfäden sind (siehe Tabelle der Figur 5): der vorherige, Figuren bildende Pol, der Polkettfaden (PIOW), der in dem Untergewebe eingebunden wird, wenn dieser nicht der jetzige oder vorherige, Figuren bildende Polkettfaden ist, der Polkettfaden (PIBW), der in dem Obergewebe eingebunden wird, wenn dieser nicht der jetzige oder vorherige, Figuren bildende Polkettfaden ist.The positions of the other pile warp threads which correspond to the different manchons can likewise be read from FIG. 5 in the same way. The other possible pile warp threads are (see table in FIG. 5): the previous figure-forming pole, the pile warp thread (PIOW), which is integrated in the lower fabric, if this is not the current or previous figure-forming pile warp thread, the pile warp thread (PIBW ), which is integrated in the upper fabric if this is not the current or previous, figure-forming pile warp thread.

Wenn ein Polkettfaden, der zum Einbinden in dem Oberteil vorgesehen ist, im Rapport D Figuren bildet (siehe Figur 6a) und dieser selbe Polkettfaden in dem nachfolgenden Bindungsrapport B wieder Figuren bildet, wobei dazwischen ein zum Einbinden in dem Unterteil vorgesehener Polkettfaden im Rapport A Figuren bildet, dann hat die zuvor erläuterte Technik, bei der der passende Manchon in Abhängigkeit von dem jetzigen, dann schon keine Figuren bildenden, zur Einbindung in dem Unter- oder Obergewebe vorgesehenen Polfaden, von dem vorherigen, dann schon keine Figuren bildenden, zur Einbindung in dem Unter- oder Obergewebe vorgesehenen Polkettfaden und vom Bindungsrapport A, B, C oder D angewendet wird, zur Folge, daß der Polkettfaden, der in dem Bindungsrapport D und B Figuren bildet, bei dem Schuß 1, 2 und 3 des dazwischen liegenden Bindungsrapportes A nicht eingebunden wird, sondern oberhalb des Obergewebes liegen wird.If a pile warp thread, which is intended for binding in the upper part, forms figures in repeat D (see FIG. 6a) and this same pile warp thread forms figures again in the subsequent binding repeat B, in between a pile warp thread intended for binding in the lower part in pattern repeat A then has the previously explained technique, in which the suitable manchon, depending on the current pile thread, which is then already forming no figures, is intended for incorporation in the lower or upper fabric, from the previous one, which is then already forming no figures, for incorporation in The pile warp thread provided for the lower or upper fabric and from the weave repeat A, B, C or D is used, as a result of which the pile warp thread, which forms figures in the weave repeat D and B, in the weft 1, 2 and 3 of the weave repeat A lying therebetween is not integrated, but will lie above the upper fabric.

Die Behebung dieses Fehlers wird in der Figur 6b für den eingebundenen Pol anschaulich gemacht, der oberhalb des Obergewebes in dem Bindungsrapport A liegt. Der eingebundene Pol wird dadurch eingebunden, daß er unter den Schuß 3 des Bindungsrapportes A gebracht wird. Diese Lösung wird systematisch, wie folgt, erreicht: Nach der Anwendung der verschiedenen, in Figur 5 erläuterten Manchons wird die erhaltene Bindung auf das Vorhandensein von Polkettfäden kontrolliert, die sich bei fünf aufeinanderfolgenden Schüssen oberhalb des Einschusses befinden. Bei diesen fünf aufeinanderfolgenden Schüssen wird dann jeweils der dritte Schuß von diesen fünf abgeändert, wobei der betreffende Polkettfaden somit unter den dritten Einschuß gebracht und auf diese Weise gut eingebunden wird.The elimination of this error is illustrated in FIG. 6b for the integrated pole, which lies above the upper fabric in the weave repeat A. The integrated pole is integrated in that it is placed under the weft 3 of the binding repeat A. This solution is achieved systematically as follows: After using the various cuffs explained in FIG. 5, the binding obtained is checked for the presence of pile warp threads which are located above the weft in five successive wefts. In these five successive wefts, the third weft is then modified from these five, the pile warp thread in question thus being brought under the third weft and thus being well integrated.

Wenn ein Polkettfaden, der zum Einbinden in dem Unterteil vorgesehen ist, in dem Rapport A Figuren bildet und dieser selbe Polkettfaden beim darauffolgenden Bindungsrapport C wieder Figuren bildet, wobei dazwischen ein zum Einbinden in dem Oberteil vorgesehener Polkettfaden in dem Rapport B Figuren bildet, dann hat dies bei der Anwendung der zuvor erläuterten Technik zur Folge, daß der Polkettfaden, der in den Rapporten A und C Figuren bildet, bei dem Schuß 1, 2 und 3 des zwischenliegenden Bindungsrapportes B nicht eingebunden wird, sondern unter dem Untergewebe liegen wird (siehe Figur 6c).If a pile warp thread, which is intended for binding in the lower part, forms figures in the repeat A and this same pile warp thread at the subsequent weave repeat C forms figures again, with a pile warp thread provided for binding in the upper part forming patterns in repeat B between them, when using the technique explained above this has the consequence that the pile warp thread forming figures in repeat A and C forms , in which weft 1, 2 and 3 of the intermediate weave repeat B is not integrated, but will lie under the lower fabric (see FIG. 6c).

Die Behebung dieses Fehlers wird in der Figur 6d für den eingebundenen Pol anschaulich gemacht, der unterhalb des Untergewebes in dem Bindungsrapport B liegt. Der eingebundene Pol wird dadurch eingebunden, daß er über den Schuß 3 des Bindungsrapportes B gebracht wird. Diese Lösung wird systematisch, wie folgt, erreicht: Nach der Anwendung der verschiedenen, in Figur 5 erläuterten Manchons wird die erhaltene Bindung auf das Vorhandensein von Polkettfäden kontrolliert, die sich fünf aufeinanderfolgende Schüsse unterhalb des Einschusses befinden. Bei diesen fünf aufeinanderfolgenden Schüssen wird dann jeweils der dritte Schuß von diesen fünf abgeändert, wobei der betreffende Polkettfaden über den dritten Einschuß gebracht und auf diese Weise gut eingebunden wird.The elimination of this error is illustrated in FIG. 6d for the integrated pole, which lies below the lower fabric in the weave repeat B. The integrated pole is integrated in that it is brought over the weft 3 of the binding repeat B. This solution is achieved systematically as follows: After using the various cuffs explained in FIG. 5, the binding obtained is checked for the presence of pile warp threads which are five consecutive wefts below the weft. In these five successive shots, the third weft is then modified from these five, the pile warp thread in question being brought over the third weft and thus being well integrated.

Schließlich kommt es, wie in Figur 7 gezeigt, auf eine Reihe von Fragen über die Stellung des Polkettfadens und den damit in Beziehung stehenden Bindungsrapport heraus, was zur Wahl des Manchons führt.Finally, as shown in Figure 7, a number of questions arise about the position of the pile warp thread and the related weave repeat, which leads to the choice of the manchon.

Der Vorteil der Arbeitsweise gemäß der Erfindung besteht im allgemeinen aus der Tatsache, daß in den beiden hergestellten Doppelstückgeweben Doppelarbeiter fehlen, während die Musterungsfeinheit vergrößert wird, wobei dieselbe Webgeschwindigkeit wie bisher beibehalten werden kann.The advantage of working according to the invention generally consists in the fact that there are no duplicators in the two double-piece fabrics produced, while the pattern fineness is increased, while the same weaving speed can be maintained as before.

Ein willkürlicher Rapport aus 6 Schuß (also 3 Schuß je Gewebe),bei dem ein Übergang von einem Figuren bildenden Polkettfaden des Untergewebes zu einem Figuren bildenden Polkettfaden des Untergewebes stattfindet, ist sowohl in dem Untergewebe als auch in dem Obergewebe mit Hilfe von 3 Polschleifen je 6 Schuß erkennbar.An arbitrary repeat of 6 wefts (i.e. 3 wefts per fabric), in which there is a transition from a figure-forming pile warp thread of the lower fabric to a figure-forming pile warp thread of the lower fabric, is in the lower fabric as well as in the upper fabric with the help of 3 pile loops each 6 shot recognizable.

Ein willkürlicher Rapport aus 6 Schuß (also 3 Schuß je Gewebe),bei dem ein Übergang von einem Figuren bildenden Polfaden des Untergewebes zu einem Figuren bildenden Polfaden des Obergewebes stattfindet, ist sowohl in dem Untergewebe als auch in dem Obergewebe mit Hilfe von 2 Polschleifen je 6 Schuß erkennbar.An arbitrary repeat of 6 wefts (i.e. 3 wefts per fabric), in which there is a transition from a figure-forming pile thread of the lower fabric to a figure-forming pile thread of the upper fabric, is in the lower fabric as well as in the upper fabric with the help of 2 pile loops each 6 shot recognizable.

Ein willkürlicher Rapport aus 6 Schuß (also 3 Schuß je Gewebe), bei dem ein Übergang von einem Figuren bildenden Polfaden des Obergewebes zu einem Figuren bildenden Polfaden des Obergewebes stattfindet, ist sowohl in dem Untergewebe als auch in dem Obergewebe mit Hilfe von 3 Polschleifen je 6 Schuß erkennbar.An arbitrary repeat of 6 wefts (ie 3 wefts per fabric), in which a transition from a figure-forming pile thread of the upper fabric to a figure-forming pile thread of the upper fabric takes place, is both in the Lower fabric as well as in the upper fabric can be recognized with the help of 3 pile loops, 6 wefts each.

Ein willkürlicher Rapport aus 6 Schuß mit einem Übergang eines figurenbildenden Polkettfadens des Obergewebes zu einem figurenbildenden Polkettfaden des Untergewebes ist sowohl in dem Untergewebe als auch in dem Obergewebe mit Hilfe von 2 Polschleifen erkennbar.An arbitrary repeat of 6 wefts with a transition from a figure-forming pile warp thread of the upper fabric to a figure-forming pile warp thread of the lower fabric can be seen in the lower fabric as well as in the upper fabric with the help of 2 pile loops.

Die Anzahl Farbpunkte in der Kartenzeichnung des Teppichs entspricht einem Drittel der Gesamtzahl Schüsse und somit der durch 1,5 geteilten Zahl der Schüsse je Teppich.The number of color dots in the map drawing of the carpet corresponds to one third of the total number of shots and thus the number of shots divided by 1.5 per carpet.

Mit Hilfe des Ablaufdiagramms gemäß Fig. 7, welches unmittelbar aus Fig. 4 abgeleitet ist, so daß auf die vorstehende ausführliche Erläuterung von Fig. 4 Bezug genommen wird, kann eine vorgegebene Kartenzeichnung ohne weiteres in eine Befehlsfolge (Schlagpatrone) für die Fachbewegung der Polfäden umgesetzt werden unter Vermeidung von Doppelarbeitern. Diese Umsetzung kann ggf. auch selbsttätig erfolgen, z.B. unter Zuhilfenahme elektronischer Datenverarbeitungsgeräte.With the aid of the flow diagram according to FIG. 7, which is derived directly from FIG. 4, so that reference is made to the above detailed explanation of FIG. 4, a predetermined map drawing can easily be converted into a command sequence (impact cartridge) for the specialist movement of the pile threads are implemented while avoiding duplication of work. This implementation can also be done automatically, e.g. with the help of electronic data processing equipment.

    Pattern repeat A: B/BW - B/OW - O/BW
    Pattern repeat B: O/OW - B/BW - B/OW
    Pattern repeat C: O/BW - O/OW - B/BW
    Pattern repeat D: B/OW - O/BW - O/OW.
  6. Method for weaving a face-to-face pile fabric according to Claim 4 or 5, characterized in that in the case of apron 17 the positions of pile warp thread 2 are changed to B - B - O (above - above - below) if apron 30 immediately follows apron 17, pile warp thread 2 in the case of apron 17 corresponding physically to pile warp thread 1 in the case of apron 30, in that in the case of apron 20 the positions of the pile warp thread 2 are changed to B - O - B (above - below - above), if apron 29 immediately follows apron 20, pile warp thread 2 in the case of apron 20 corresponding physically to pile warp thread 1 in the case of apron 29, and in that in the case of apron 29 the positions of pile warp thread 2 are changed to O - B - O (below - above - below), if apron 18 immediately follows apron 29, pile warp thread 2 in the case of apron 29 corresponding physically to pile warp thread 1 in the case of apron 18, and in that in the case of apron 30 the positions of pile warp thread 2 are changed to O - O - B (below - below - above), if apron 19 immediately follows apron 30, pile warp thread 2 in the case of apron 30 corresponding physically to pile warp thread 1 in the case of apron 19.
  7. Method according to one of Claims 3 - 6, characterized in that, on the basis of a card design indicating a patterning of the face-to-face pile fabric to be woven, the aprons are determined by the following steps:
    (a) starting from a specific initial pick, the successive picks are divided into groups of three (working pattern repeats) and, starting from an initial index A, are provided with rising index (B, C, D) until the first working pattern repeat recurs, following which one begins again with the initial index A, the working pattern repeats being distinguished from one another by the position of the three weft threads (IB1,...) above or below at least several tension warp threads (SB, SO) and tied-in pile warp threads (P1,...) of the top and bottom fabric (BW, OW);
    b) for each working pattern repeat of the various working pattern repeats occurring-, a number of possible aprons are set up for the positions of the pile warp threads (P1,...) in each working pattern repeat; and
    c) in the conversion of the card design to aprons, for each row each point of the card design is allocated an apron each time over three picks through a derivation of the relevant working pattern repeat and through a selection of the suitable apron for this point from among a number of aprons which could be used for this working pattern repeat.
  8. Method according to Claim 8, characterized in that in step b) for each possible pile warp thread configuration in a working pattern repeat several aprons are set up according to the possible combinations of each pile warp thread configuration with pile warp thread configurations from an immediately preceding working pattern repeat, following which in step c) the apron which is suitable for the combination of the present pile warp thread configuration with the immediately preceding pile warp thread configuration is selected.
  9. Method according to Claim 7 or 8, characterized in that, if over three successive picks of the particular backing fabric a non-pattern-forming pile warp thread (P1,...) of the top or bottom fabric (BW, OW) always lies on the outside with respect to the fabrics of these three picks which lie opposite each other and are viewed as common fabrics, the apron is corrected in such a way for the middle pick of the three picks that the non-pattern-forming pile warp thread (P1,...) is tied in at the inside of the middle pick of the backing fabric in question.
  10. Face-to-face pile fabric manufactured by the method according to one of the preceding claims.
