Description

Die Erfindung betrifft ein textiles Flächengebilde gemäss Oberbegriff des Anspruches 1, sowie ein Verfahren zu dessen Herstellung gemäss Oberbegriff des Anspruches 14 und eine Kettenwirkmaschine zur Durchführung des Verfahrens gemäss Oberbegriff des Anspruches 18.The invention relates to a textile fabric according to the preamble of claim 1, a method for its production according to the preamble of claim 14 and a warp knitting machine for carrying out the method according to the preamble of claim 18.

Textile Flächengebilde, die ein Grundgewirk aufweisen mit dem Musterfäden verbunden sind, Verfahren zu deren Herstellung und entsprechende Kettenwirkmaschinen sind in zahlreichen Ausführungsformen bekannt und es wird hier lediglich beispielsweise auf die DE-OSen 27 21 024,27 58 421 und 29 33 841 verwiesen.Textile fabrics which have a basic knitted fabric to which pattern threads are connected, processes for their production and corresponding warp knitting machines are known in numerous embodiments and reference is only made here, for example, to DE-OSen 27 21 024, 27 58 421 and 29 33 841.

Aufgabe der Erfindung ist es, ein neuartiges textiles Flächengebilde mit einer neuartigen Mustermöglichkeit zu schaffen, sowie ein Verfahren und eine Kettenwirkmaschine zu dessen Herstellung anzugeben.The object of the invention is to create a new type of textile fabric with a new type of pattern, and to specify a method and a warp knitting machine for its production.

Die Aufgabe wird erfindungsgemäss gelöst durch:

  • a) ein textiles Flächengebilde gemäss Anspruch 1;
  • b) ein Verfahren zur Herstellung des textilen Flächengebildes gemäss Anspruch 14 und
  • c) eine Kettenwirkmaschine zur Durchführung des Verfahrens gemäss Anspruch 18.
According to the invention, the object is achieved by:
  • a) a textile fabric according to claim 1;
  • b) a method for producing the fabric according to claim 14 and
  • c) a warp knitting machine for performing the method according to claim 18.

Das neuartige textile Flächengebilde zeichnet sich durch eine besonders ausgeprägte aufgesetzte Musterung aus, wobei Musterung hier im allgemeinsten Sinne verstanden werden soll und auch technische Aspekte beinhalten soll. So kann beispielsweise der Musterfaden relativ dick ausgeführt werden und Oesen bilden, die beispielsweise zur Befestigung dienen können, wie dies bei Gardinenbändern zur Befestigung von Gleitern und Rollen der Fall ist. Im übrigen kann der Musterfaden die verschiedensten Farben aufweisen, und in den verschiedensten Formen gelegt sein wie z.B. zu Figuren, Picots, Fransen usw. Auch die Anordnung mehrer verschiedener farbiger Musterfäden ist möglich. Ein solches textiles Flächengebilde weist auf der der Musterung abgewandten Seite eine glatte Fläche auf, sodass eine Verbindung mit einem anderen Gebilde, z.B. einem Kleidungsstück einfacher und für dieses schonender ist. Auch das Tragen eines solchen Flächgebildes am Körper einer Person ist angenehmer. Das Flächengebilde kann porös gemacht werden und trotzdem eine Quersteifigkeit aufweisen, indem zusätzliche Schussfäden eingelegt werden. Beim in die Längeziehen behält das Flächengebilde seine Breite bei.The innovative textile fabric is characterized by a particularly pronounced pattern, whereby patterning should be understood in the most general sense and should also include technical aspects. For example, the pattern thread can be made relatively thick and form eyelets that can be used, for example, for fastening, as is the case with curtain tapes for fastening gliders and rollers. Otherwise, the pattern thread can have a wide variety of colors and be laid out in a wide variety of shapes, e.g. to figures, picots, fringes etc. The arrangement of several different colored pattern threads is also possible. Such a textile fabric has a smooth surface on the side facing away from the pattern, so that a connection with another structure, e.g. a garment is easier and gentler for it. Wearing such a flat image on a person's body is also more pleasant. The fabric can be made porous and still have transverse rigidity by inserting additional weft threads. When stretching, the fabric retains its width.

Vorteilhafte Ausgestaltungen des textilen Flächengebildes sind in den Ansprüchen 2 bis 13 beschrieben, vorteilhafte Ausgestaltungen des Verfahrens in den Ansprüchen 15 bis 17 und vorteilhafte Ausgestaltungen der Kettenwirkmaschine in den Ansprüchen 19 und 20.Advantageous configurations of the textile fabric are described in claims 2 to 13, advantageous configurations of the method in claims 15 to 17 and advantageous configurations of the warp knitting machine in claims 19 and 20.

Es ist grundsätzlich möglich, den Hilfskettfaden nach Art eines Nähwirkverfahrens mit dem Grundgewirk zu verbinden. Wesentlich einfacher und festigkeitsmässig günstiger ist eine Ausbildung nach Anspruch 2. Es ist möglich, mindestens einen Hilfskettfaden gemäss Anspruch 3 anzuordnen, wobei sowohl eine Ausgestaltung nach Anspruch 4 als auch nach Anspruch 5 möglich ist. In der Regel werden Hilfskettfäden jedoch innerhalb des Grundgewebes angeordnet. Die Maschenstäbchen der Hilfskettfäden können gemäss Anspruch 6 benachbart sein oder gemäss Anspruch 7 Abstand voneinander aufweisen. Im letzteren Falle ergibt sich eine grössere Stabilität der Befestigung des Musterfadens am Grundgewirk. Falls ein freies Aufliegen des Musterfadens auf dem Grundgewirk unerwünscht ist, können soviele Hilfskettfäden angeordnet werden, dass die ganze Breite der Musterung erfasst wird. Von Vorteil ist es jedoch, wenn der Musterfaden teilweise frei am Grundgewirk anliegt, wobei insbesondere eine Ausbildung nach Anspruch 8 von Vorteil ist, die auch eine Ausgestaltung nach Anspruch 9 ermöglicht. Der Musterfaden kann an jeder Maschenreihe angebunden werden, vorteilhaft ist jedoch eine Ausgestaltung nach Anspruch 10, wobei dann der Musterfaden zwischen benachbarten Anbindungen über ein oder mehrere Maschenreihen frei liegt.It is fundamentally possible to connect the auxiliary warp thread to the basic knitted fabric in the manner of a sewing process. An embodiment according to claim 2 is considerably simpler and less expensive in terms of strength. It is possible to arrange at least one auxiliary warp thread according to claim 3, both an embodiment according to claim 4 and according to claim 5 being possible. As a rule, however, auxiliary warp threads are arranged within the base fabric. According to claim 6, the wales of the auxiliary warp threads can be adjacent or be spaced apart according to claim 7. In the latter case, there is greater stability in the attachment of the pattern thread to the basic knitted fabric. If a free resting of the pattern thread on the base fabric is undesirable, so many auxiliary warp threads can be arranged that the entire width of the pattern is covered. However, it is advantageous if the pattern thread lies partially freely against the basic knitted fabric, an embodiment according to claim 8, which also enables an embodiment according to claim 9, to be particularly advantageous. The pattern thread can be tied to each row of stitches, but an embodiment according to claim 10 is advantageous, in which case the pattern thread is exposed between adjacent connections over one or more rows of stitches.

Der Musterfaden kann ein nicht dehnbarer Faden oder ein elastischer Faden gemäss Anspruch 11 sein. Die Stärke des Musterfadens kann jener der Fäden des Grundgewirks oder der Hilfskettfäden entsprechen. Vorteilhaft ist jedoch eine Ausgestaltung nach Anspruch 12. Ein dickerer Musterfaden begünstigt dabei nicht nur die Musterbildung, sondern gestattet es auch, dem Muster eine technische Bedeutung zu geben. So kann der Musterfaden beispielsweise in Fransen bzw. Schlaufen gelegt werden, die seitlich des Grundgewirks vorstehen und zur Befestigung von Haken und Oesen dienen, so wie dies beispielsweise für Gardinenbänder der Fall ist.The pattern thread can be a non-stretchable thread or an elastic thread according to claim 11. The thickness of the pattern thread can correspond to that of the threads of the basic knitted fabric or the auxiliary warp threads. However, an embodiment according to claim 12 is advantageous. A thicker pattern thread not only favors the pattern formation, but also allows the pattern to be given a technical meaning. For example, the pattern thread can be placed in fringes or loops that protrude laterally from the basic knitted fabric and are used to fasten hooks and eyes, as is the case for curtain tapes, for example.

Der Anspruch 14 beinhaltet ein besonders einfaches Verfahren und der Anspruch 18 eine besonders einfache Kettenwirkmaschine zur Herstellung des textilen Flächengebildes.Claim 14 contains a particularly simple method and claim 18 a particularly simple warp knitting machine for producing the textile fabric.

Die Kettenwirkmaschine kann zweckmässigerweise nach Anspruch 19 weitergebildet sein, wenn freiliegende Schlaufen bzw. Fransen gebildet werden sollen. Zweckmässig ist auch eine Ausgestaltung nach Anspruch 20.The warp knitting machine can expediently be developed according to claim 19 if exposed loops or fringes are to be formed. An embodiment according to claim 20 is also appropriate.

  • Figur 6 die Kettenwirkmaschine der Figur 5 in der Phase des Einlegens der Kettfäden und der Hilfskettfäden.
Exemplary embodiments of the subject matter of the invention are described in more detail below with reference to the drawings, in which:
  • Figure 1 shows a first textile fabric in the cutout;
  • Figure 2 shows a second textile fabric in the cutout;
  • Figure 3 shows a third textile fabric in the cutout;
  • Figure 4 shows a fourth textile fabric in the detail;
  • Figure 5 shows the knitting area of a warp knitting machine in the phase after knitting off the stitches, in side view and in a schematic representation;

Die Figur 1 zeigt ein textiles Flächengebilde, welches ein Grundgewirk 2 aufweist, das aus einzelnen Maschenstäbchen 4 gebildet ist, die aus Kettfäden 6 bestehen. Die Maschenstäbchen 4 sind durch Schüsse 8 eines Schussfadens 10 miteinander verbunden. Auf der dargestellten Seite des Grundgewirkes 2 liegt ein Musterfaden 12, der mittels zweier Hilfskettfäden 14 mit dem Grundgewirk 2 verbunden ist. Hierzu sind die Hilfskettfäden 14 jeweils zusammen mit einem Kettfaden 6 zu den Maschenstäbchen 4 verwirkt, wobei der Musterfaden 12 jeweils zwischen dem Kettfaden 6 und dem Hilfskettfaden 14 verläuft. Die Maschenstäbchen der Hilfskettfäden 14 sind mit Abstand voneinander angeordnet, der im gezeigten Beispiel 3 Maschenstäbchen 4 beträgt. Der Musterfaden 12 ist nicht an jeder Maschenreihe 16 eingebunden, sondern im gezeigten Beispiel nur an den Maschenreihen 161, 162, dann 164,165 und 167, Dazwischen verläuft der Musterfaden 12 freiliegend. Der Musterfaden verläuft zick-zack-förmig am Grundgewirk.FIG. 1 shows a textile fabric which has a basic knitted fabric 2, which is formed from individual wales 4, which consist of warp threads 6. The wales 4 are connected to one another by wefts 8 of a weft thread 10. On the side of the base fabric 2 shown there is a pattern thread 12 which is connected to the base fabric 2 by means of two auxiliary warp threads 14. For this purpose, the auxiliary warp threads 14 are each knitted together with a warp thread 6 to the wales 4, the pattern thread 12 each running between the warp thread 6 and the auxiliary warp thread 14. The wales of the auxiliary warp threads 14 are arranged at a distance from one another, which in the example shown is 3 wales 4. The pattern thread 12 is not integrated on each stitch row 16, but in the example shown only on the stitch rows 16 1 , 16 2 , then 16 4 , 16 5 and 16 7 , in between the pattern thread 12 is exposed. The pattern f threads extending zig-zag manner on the ground construction.

Die Figur 2 zeigt ein weiteres Ausführungsbeispiel eines Flächengebildes, welches im wesentlichen jenem der Figur 1 entspricht, sodass gleiche Teile mit gleichen Bezugszeichen versehen sind. Im Gegensatz zum Beispiel der Figur 1 sind die Hilfskettfäden bzw. deren Maschenstäbchen 14a nebeneinanderliegend angeordnet. Der Musterfaden 12a ist so gelegt, dass er seitlich über das Grundgewirk 2 hinausragende Fransen 18 bildet. Zur Herstellung der Fransen sind die in Figur 2 angedeuteten Stecher 20 erforderlich, die beim seitlichen Auslenken des Musterfadens 12a in dessen Bewegungsbereich eingefahren werden und ein Zurückziehen des Musterfadens beim weiteren Legen desselben verhindern. Mit dem seitlich vorstehenden Musterfaden kann auch ein weiteres Grundgewirk analog angeschlossen werden (nicht dargestellt).FIG. 2 shows a further exemplary embodiment of a flat structure which essentially corresponds to that of FIG. 1, so that the same parts are provided with the same reference symbols. In contrast to the example in FIG. 1, the auxiliary warp threads or their wales 14a are arranged side by side. The pattern thread 12a is laid in such a way that it forms fringes 18 projecting laterally beyond the basic knitted fabric 2. For the production of the fringes, the piercers 20 indicated in FIG. 2 are required, which are moved into the movement area of the pattern thread 12a when the pattern thread 12a is laterally deflected and prevent the pattern thread from being retracted when it is further laid. Another basic knitted fabric can also be connected analogously (not shown) with the pattern thread protruding to the side.

Gegenbenenfalls ist es auch möglich, einen zusätzlichen Hilfskettfaden 14b ausserhalb des Grundgewirkes anzuordnen, wie dies auf der linken Seite der Figur 3 gestrichelt angedeutet ist. Dadurch lassen sich der Mustereffekt bzw. die Stabilität der angeordneten Fransen erhöhen.In the same way, it is also possible to arrange an additional auxiliary warp thread 14b outside the basic knitted fabric, as is indicated by dashed lines on the left side of FIG. 3. This allows the pattern effect or the stability of the fringes to be increased.

Die Figur 3 zeigt ein weiteres textiles Flächengebilde, mit einem Grundgewirk, welches zu Maschenstäbchen 4 gewirkte Kettfäden 6 aufweist, die durch Schüsse 8 eines Schussfadens verbunden sind. Dieses Flächengebilde enthält drei in Bahnen 21a, 21b, 21c schussartig angeordnete Musterfäden 12b, 12c, 12d, die jeweils über drei Maschenstäbchen der Kettfäden 6 verlaufen. Die Kopfenden der zick-zack-förmig gelegten Musterfäden sind jeweils mittels eines Hilfskettfadens 14c, 14d am Grundgewirk angebunden, wobei die Hilfskettfäden jeweils zusammen mit einem Kettfaden 6 zu Maschenstäbchen 4a, 4b verwirkt sind. An den mittleren Maschenstäbchen 4b sind jeweils die Kopfenden der Schlaufen der Musterfäden 12b, 12c, 12d benachbarter Bahnen 21a, 21b bzw. 21b, 21c mittels eines Hilfskettfadens 14d gemeinsam am Grundgewirk befestigt. Die Musterfäden 12b, 12c, 12d können verschiedene Farben aufweisen, wodurch beispielsweise ein Flächengebilde mit drei verschiedenen Farbbahnen gebildet ist.FIG. 3 shows a further flat textile structure, with a basic knitted fabric which has warp threads 6 knitted into wales 4, which are connected by wefts 8 of a weft thread. This flat structure contains three pattern threads 12b, 12c, 12d arranged in tracks 21a, 21b, 21c, each of which runs over three wales of the warp threads 6. The head ends of the zigzag pattern threads are each connected to the basic knitted fabric by means of an auxiliary warp thread 14c, 14d, the auxiliary warp threads being knitted together with a warp thread 6 to form wales 4a, 4b. The head ends of the loops of the pattern threads 12b, 12c, 12d of adjacent webs 21a, 21b and 21b, 21c are fastened together to the basic knitted fabric by means of an auxiliary warp thread 14d on the middle wales 4b. The pattern threads 12b, 12c, 12d can have different colors, as a result of which, for example, a flat structure is formed with three different color paths.

Die Figur 4 zeigt ein textiles Flächengebilde, welches jenem der Figur 2 entspricht, wobei jedoch der in Fransen gelegte Musterfaden 12a mittels Hilfskettfäden 14e am Grundgewirk befe.- stigt sind, die zu Maschenstäbchen 4c verwirkt sind, welche unabhängig von den Maschenstäbchen der Kettfäden 6 sind und lediglich den Musterfaden 12a und den Schussfaden 10 des Grundgewirkes einschliessen.FIG. 4 shows a textile fabric which corresponds to that of FIG. 2, but the pattern thread 12a laid in fringes is attached to the basic knitted fabric by means of auxiliary warp threads 14e, which are knitted into wales 4c, which are independent of the wales of the warp threads 6 and only include the pattern thread 12a and the weft thread 10 of the basic knitted fabric.

Die Figuren 5 und 6 zeigen den Wirkbereich einer Kettenwirkmaschine zur Herstellung des oben erwähnten textilen Flächengebildes. Der übrige Aufbau einer solchen Kettenwirkmaschine ist hinlänglich bekannt und beispielsweise in den eingangs genannten Druckschriften beschrieben. Die Kettenwirkmaschine enthält eine Abschlagplatine 22, in der hin- und hergehende Wirknadeln 24, beispielsweise Häkelnadeln, geführt sind. Die Figur 5 zeigt die Ausgangsstellung, in der die Wirknadeln 24 in der zurückgezogenen Stellung nach dem Abschlagen der Maschen gezeigt sind. Das fertige Flächengebilde 26 wird nach unten mittels einer Abzugsvorrichtung 27 abgezogen. Den Wirknadeln ist ein Schussfadenführer 28 zugeordnet, der an einer Schusslegestange 30 angeordnet ist und zum Zuführen des Schussfadens 10 dient. Weiter sind Kettfadenführer 32 vorhanden, die an einer Kettenlegeschiene 34 angeordnet sind und die Kettfäden 6 den Wirknadeln 24 zuführen. Mit diesen Einrichtungen kann das Grundgewirk hergestellt werden.FIGS. 5 and 6 show the knitting area of a warp knitting machine for producing the above-mentioned textile fabric. The rest of the structure of such a warp knitting machine is well known and is described, for example, in the publications mentioned at the beginning. The warp knitting machine contains a knock-off board 22 in which reciprocating knitting needles 24, for example crochet hooks, are guided. FIG. 5 shows the starting position, in which the knitting needles 24 are shown in the retracted position after the stitches have been cast off. The finished fabric 26 is pulled down by means of a pull-off device 27. A weft thread guide 28 is assigned to the knitting needles, which is arranged on a weft laying rod 30 and serves to feed the weft thread 10. There are also warp thread guides 32, which are arranged on a warp guide rail 34 and feed the warp threads 6 to the knitting needles 24. The basic fabric can be produced with these devices.

Zur Musterung des Grundgewirkes dienen Hilfskettfadenführer 36, die an einer Hilfskettenlegestange 38 angeordnet sind. Die Hilfskettfadenführer 36 sind vorne, d.h. auf der Seite der Kettfadenführer 32 angeordnet, die dem Schussfadenführer 28 abgewandt ist. Zwischen dem Hilfskettfadenführer 36 und dem Kettfadenführer 32 ist der Musterfadenführer 40 angeordnet, der an einer Musterfadenlegestange 42 befestigt ist. Zur Schlaufenbildung des Musterfadens ist schliesslich ein Stecher 20 vorhanden, der an einer entsprechenden Führungstange 44 befestigt ist und in die Laufbahn des seitlich ausgelenkten Musterfadens 12a eingeschwenkt werden kann. Zur Bildung von seitlich des Grundgewirkes anzuordnenden Fransen 18 kann der Stecher 20 ausserhalb des Endes der Wirknadelreihe zwischen dem Schussfadenführer 28 und dem Kettfadenführer 32 angeordnet sein.Auxiliary warp thread guides 36, which are arranged on an auxiliary chain laying bar 38, serve to pattern the basic knitted fabric. The auxiliary warp thread guides 36 are at the front, i.e. arranged on the side of the warp thread guide 32 which faces away from the weft thread guide 28. Between the auxiliary warp thread guide 36 and the warp thread guide 32, the pattern thread guide 40 is arranged, which is fastened to a pattern thread laying rod 42. Finally, to form the loop of the pattern thread there is a piercer 20 which is fastened to a corresponding guide rod 44 and can be pivoted into the track of the pattern thread 12a which is deflected laterally. To form fringes 18 to be arranged on the side of the basic knitted fabric, the piercer 20 can be arranged outside the end of the knitting needle row between the weft thread guide 28 and the warp thread guide 32.

Die Herstellung des Flächegebildes erfolgt in der Weise, dass nach dem Abschlagen der Maschen, wie dies in Figur 5 dargestellt ist, mittels des Schussfadenführers 28 und des Musterfadenführers 40 der Schussfaden 10 und der Musterfaden 12a in der gewünschten Weise gelegt werden. Der Stecher 20 sorgt dabei dafür, dass der Musterfaden 12a nicht glattgezogen wird sondern eine Franse bzw. Schlaufe bildet. Sobald der Schussfaden 10 und der Musterfaden 12a gelegt sind, werden die Wirknadeln 24 in die in Figur 6 gezeigte Stellung ausgefahren und der Kettfaden 6 mittels des Kettfadenführers 32 und der Hilfskettfaden 14 mittels des Hilfskettfadenführers 36 über die Wirknadeln 24 gelegt. Beim Zurückziehen der Wirknadeln 24 in die in Figur 5 gezeigte Stellung werden dann die von der Wirknadel aufgenommenen Kettfäden 6 und Hilfskettfäden 14 durch die am Nadelschaft befindlichen Maschenschleifen 46 gezogen und letztere abgeschlagen.The flat image is produced in such a way that after the stitches have been knocked off, as shown in FIG. 5, the weft thread 10 and the pattern thread guide 40 are used to lay the weft thread 10 and the pattern thread 12a in the desired manner. The piercer 20 ensures that the pattern thread 12a is not pulled smooth but forms a fringe or loop. As soon as the weft thread 10 and the pattern thread 12a have been laid, the knitting needles 24 are extended into the position shown in FIG. 6 and the Warp thread 6 by means of the warp thread guide 32 and the auxiliary warp thread 14 by means of the auxiliary warp thread guide 36 are placed over the knitting needles 24. When the knitting needles 24 are pulled back into the position shown in FIG. 5, the warp threads 6 and auxiliary warp threads 14 picked up by the knitting needle are then pulled through the stitch loops 46 located on the needle shaft and the latter knocked off.
