Description

Die Erfindung betrifft eine Rundwebmaschine.The invention relates to a circular loom.

Es sind allgemein Rundwebmaschinen bekannt, bei welchen Kettbändchen-Führungselemente, z.B. in Form von Längenausgleichskompensatoren, um das Rundriet der Rundwebmaschine herum angeordnet sind. Über diese Kettbändchen-Führungselemente oder durch sie hindurch wird der Rundwebmaschine eine große Zahl von Kettbändchen ringsum verteilt zugeführt. Von den Kettbändchen-Führungselementen laufen die Kettbändchen zu Fachbildungseinrichtungen, die beispielsweise mit Ösen zum Hindurchführen je eines Kettbändchens versehene Litzen oder Bänder aufweisen; anschließend laufen die Kettbändchen zwischen Stäben des Rundriets hindurch. Die Kettbändchen werden an den Fachbildungseinrichtungen - zumeist in abwechselnder Anordnung - in zwei Kettbändchenscharen aufgeteilt, denen durch entgegengesetzte Bewegung der Litzen oder Ösenbänder einander entgegengesetzte Wechselbewegungen verliehen werden, wodurch das Webfach (auch Wanderfach genannt) geöffnet und geschlossen wird. Das Webfach bildet im geöffneten Zustand einen von den beiden Kettbändchenscharen definierten Raum, in dem sich ein Webschützen, der eine Schussbändchenspule trägt, auf einer Kreisbahn entlang des Rundriets bewegt und dabei das Schussbändchen von der von ihm getragenen Schussbändchenspule abzieht und in das Webfach einträgt. Die Größe des von den beiden Kettbändchenscharen definierten Raumes des Webfachs ändert sich ständig mit der Bewegung der beiden Kettbändchenscharen, ausgehend von Null bei geschlossenem Webfach in einer Stellung, in der beide Kettbändchenscharen in derselben Fläche liegen, bis zu einem Maximum, bei dem sich die beiden Kettbändchenscharen an entgegengesetzten Umkehrpunkten ihrer Wechselbewegung befinden. An diesen Umkehrpunkten beginnt der so genannte Fachwechsel durch Umkehr der den gegenläufigen Kettbändchenscharen verliehenen Bewegung, wodurch das zuletzt eingetragene Schussbändchen im Gewebe fixiert wird und vom nächsten Schützen das nächste Schussbändchen in das Webfach eingetragen werden kann. Es laufen üblicherweise mehrere Webschützen in gleichen Abständen voneinander im Rundriet um. Das erzeugte schlauchförmige Gewebe wird nach innen zu einem zentral angeordneten Webring geführt, an dem es zu Abzugsrollen hin umgelenkt wird.There are generally known circular looms in which warp guide elements, e.g. in the form of length compensation compensators, around the Rundriet the loom around are arranged. About this Kettbändchen guide elements or through them the circular loom a large number of warp is distributed around distributed. Of the Kettbändchen guide elements, the warp tapes run to shedding facilities, for example, have provided with eyelets for passing through each of a warp strip provided with strands or bands; then the warp-ribbons run between bars of the Rundriets. The warp tapes are divided at the shedding devices - usually in an alternating arrangement - in two Kettbändchenscharen, which are given by opposite movement of the strands or Ösenbänder opposite alternating movements, whereby the shed (also called moving compartment) is opened and closed. The shed forms in the open state defined by the two Kettbändchenscharen space in which a weaver who wears a Schussbändchenspule moves on a circular path along the Rundriets while the Schussbändchen deducted from the shot ribbon coil carried by him and enters into the shed. The size of the space defined by the two Kettbändchenscharen space of the shed constantly changes with the movement of the two Kettbändchenscharen, starting from zero with a closed shed in a position in which both Kettbändchenscharen lie in the same area, up to a maximum, in which the two Kettbändchenscharen are located at opposite reversal points of their alternating movement. At these reversal points, the so-called change of subject begins by reversing the movement imparted to the opposing warp bands, whereby the last-entered weft ribbon is fixed in the fabric and the next weft ribbon can be inserted into the shed by the next shooter. There are usually several weavers at the same distance from each other in Rundriet around. The generated tubular fabric is guided inwardly to a centrally located Webring, where it is deflected to take-off rolls out.

Eine solche Rundwebmaschine ist beispielsweise aus der EP 0 786 026 B1 bekannt. Aus dem Dokument US 1947976 A ist eine Schussbändchenspule bekannt, bei der der Spulendurchmesser größer ist als die Spulenlänge, siehe Fig. 2.Such a circular loom is for example from the EP 0 786 026 B1 known. From the document US 1947976 A is known a Schussbändchenspule, wherein the coil diameter is greater than the coil length, see Fig. 2 ,

Es bestand seit jeher das Bedürfnis, die Leistung von Rundwebmaschinen zu erhöhen. Die Gesamtleistung der Rundwebmaschine wird maßgeblich von der sogenannten Schusszahl beeinflusst, das ist die Anzahl an Schussbändchen, die pro Zeiteinheit in das Webfach eingetragen werden können. Die Schusszahl wird üblicherweise in "picks per minute" angegeben. Die Schusszahl wurde in der Vergangenheit durch die Erhöhung der Umlaufgeschwindigkeit der Schützen im Rundriet und/oder die Erhöhung der Schützenanzahl gesteigert. In der EP0167831A1 wurde zum Beispiel eine Erhöhung der Umlaufgeschwindigkeit durch die spezielle Ausgestaltung der Laufbahnen, auf denen die Stützrollenpaare der Webschützen im Riet laufen, erreicht. Diese speziell ausgestalteten Laufbahnen erhöhten die Laufruhe der Webschützen, was eine geringere Abnutzung des Riets zur Folge hatte und dadurch eine höhere Umlaufgeschwindigkeit erlaubte.There has always been a need to increase the performance of looms. The overall performance of the circular loom is significantly influenced by the so-called number of shots, which is the number of weft tapes that can be entered per unit time in the shed. The number of shots is usually given in "picks per minute". The number of shots has been increased in the past by increasing the speed of rotation of the shooters in Rundriet and / or increasing the number of shooters. In the EP0167831A1 For example, an increase in orbital speed has been achieved by the special design of the raceways on which the shuttle pairs of the shuttle members are running. These specially designed raceways increased the smoothness of the weavers, resulting in less wear of the reed and thereby allowing a higher speed of rotation.

Mittlerweile ist man jedoch an die Leistungsgrenzen von Rundwebmaschinen gestoßen, wobei der limitierende Faktor vor allem die Belastbarkeit der Bauelemente ist, auf welche die Fliehkraft der Webschützen wirkt. Insbesondere die Führungselemente, auf denen die Webschützen entlang des Rietes laufen, werden durch die Fliehkraft der rotierenden Webschützen belastet und abgenutzt. Die Fliehkraft hängt in erster Linie von der Masse der Webschützen, der Umlaufgeschwindigkeit (bzw. Drehzahl) und dem Rietradius ab. Mit jeder Erhöhung der einzelnen Parameter wird die Fliehkraft und somit die Belastung und Abnutzung der Bauelemente erhöht.Meanwhile, however, one has encountered the performance limits of looms, the limiting factor is mainly the resilience of the components on which the centrifugal force of the weavers acts. In particular, the guide elements on which the weavers run along the reed are loaded and worn by the centrifugal force of the rotating shuttle. The centrifugal force depends primarily on the mass of the weavers, the rotational speed (or speed) and the Rietradius. With each increase in the individual parameters, the centrifugal force and thus the load and wear of the components is increased.

Obwohl die Belastungsfähigkeit der Bauelemente, auf welche die Fliehkraft wirkt, durch Erhöhung der Schützenanzahl und der Drehzahl der Hauptwelle, die die Schützen antreibt, sowie der Verringerung der Webschützenmasse scheinbar ausgereizt ist, strebt die Industrie weiterhin nach einer Erhöhung der Schusszahl von Rundwebmaschinen.Although the load capacity of the components on which the centrifugal force acts seem to be exhausted by increasing the number of shooters and the speed of the main shaft which drives the shooters, as well as the reduction of the shuttleman mass, the industry continues to seek an increase in the number of round looms.

Es ist daher die Aufgabe der Erfindung die Schusszahl an Rundwebmaschinen zu steigern, ohne die Belastung und Abnutzung der Bauelemente durch die von den rotierenden Webschützen ausgeübte Fliehkraft zu erhöhen, sondern im Gegenteil sogar zu vermindern.It is therefore an object of the invention to increase the number of round looms, without increasing the load and wear of the components by the force exerted by the rotating shuttle centrifugal force, but on the contrary even to reduce.

Die vorliegende Erfindung löst diese Aufgabe durch Bereitstellen einer Rundwebmaschine mit den Merkmalen des Anspruchs 1. Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargelegt.The present invention solves this problem by providing a circular loom with the features of claim 1. Preferred embodiments of the invention are set forth in the subclaims.

Die erfindungsgemäße Rundwebmaschine umfasst:

  • Kettbändchen-Führungselemente, die um ein Rundriet der Rundwebmaschine herum zur Zuführung einer Vielzahl von Kettbändchen zur Rundwebmaschine angeordnet sind;
  • Webfachbildungseinrichtungen, die die zugeführten Kettbändchen in zwei Kettbändchenscharen aufteilen und den beiden Kettbändchenscharen einander entgegengesetzte Wechselbewegungen verleihen, wodurch zwischen den beiden Kettbändchenscharen ein Webfach geöffnet und geschlossen wird;
  • einen Webschützen, der sich auf einer Umlaufbahn im geöffneten Webfach bewegt und während seines Umlaufs ein Schussbändchen von einer von ihm getragenen Schussbändchenspule abzieht und in das Webfach einträgt, wodurch ein Gewebe gebildet wird; und
  • einen Webring, durch den hindurch das Gewebe abgezogen wird;
  • wobei der Webschützen die Spulenachse der Schussbändchenspule in einer Winkelstellung hält, die maximal +/- 15°, bevorzugt maximal +/- 10°, von einer Normalen auf eine Fläche abweicht, die die geometrischen Verbindungslinien zwischen den Kettbändchen-Führungselementen und dem Webring enthält.
The circular loom according to the invention comprises:
  • Warp-tape guide elements arranged around a round pile of the circular loom for feeding a plurality of warp ribbons to the loom;
  • Shed forming means which divide the supplied warp tapes into two warp sheet coulters and impart opposite alternating movements to the two warp sheet coats, whereby a shed is opened and closed between the two warp sheet sheets;
  • a shuttle that moves in an orbit in the open shed and during its revolution draws a weft ribbon from a weft ribbon spool carried by it and enters the shed, thereby forming a web; and
  • a Webring, through which the fabric is pulled off;
  • wherein the weaver keeps the spool axis of the weft ribbon spool in an angular position which deviates at most +/- 15 °, preferably at most +/- 10 °, from a normal to a surface containing the geometric connecting lines between the warp-tie guiding elements and the weaving ring.

Die Fläche, die die geometrischen Verbindungslinien zwischen den Kettbändchen-Führungselementen und dem Webring enthält, entspricht im Betrieb des Webstuhls der Fläche, die bei geschlossenem Webfach von den beiden Kettbändchenscharen gemeinsam gebildet wird. Weiters sind bei einer bevorzugten Anordnung der Kettbändchen-Führungselemente die geometrischen Verbindungslinien radial zwischen den Kettbändchen-Führungselementen und dem Webring angeordnet.In the operation of the loom, the surface containing the geometrical connecting lines between the warp guide elements and the weaving ring corresponds to the surface which is formed jointly by the two warp bands when the shed is closed. Furthermore, in a preferred arrangement of the warp-tape guide elements, the geometric connecting lines are arranged radially between the warp-tape guiding elements and the weaving ring.

Verglichen mit herkömmlichen Rundwebmaschinen, bei denen die Spulenachse der Schussbändchenspule vom Webschützen im Wesentlichen waagrecht gehalten wird, kann durch die erfindungsgemäße Anordnung der Spulenachse der Schussbändchenspule in einer Winkelstellung, die maximal +/- 15°, bevorzugt maximal +/- 10°, von einer Normalen auf die Fläche des geschlossenen Webfaches abweicht, die Baulänge des Webschützen und somit seine Masse reduziert werden, was wiederum das Vorsehen einer höheren Anzahl von Webschützen bei gleichem Rietradius erlaubt. Die höhere Anzahl an Webschützen erlaubt die Reduzierung der Umlaufgeschwindigkeit der Schützen, wobei in Summe die Schusszahl der Rundwebmaschine gegenüber dem Stand der Technik gesteigert wird, ohne dass sich die auf die fliehkraftbelasteten Bauelemente, wie Schützenrollen, Rundriet, etc. wirkenden (Flieh)kräfte erhöhen.Compared with conventional looms, in which the spool axis of the weft ribbon spool is held substantially horizontally by the weaver, can by the inventive arrangement of the coil axis of the weft ribbon spool in an angular position, the maximum +/- 15 °, preferably a maximum of +/- 10 °, from a Normal deviates to the surface of the closed shed, the length of the weaver and thus its mass are reduced, which in turn allows the provision of a higher number of weavers with the same Rietradius. The higher number of weavers allows the reduction of the speed of rotation of the shooter, in sum, the number of rounds of the circular loom over the prior art is increased without the centrifugal force loaded components, such as shooters, Rundriet, etc. acting (centrifugal) forces increase ,

Eine Optimierung der erwähnten Vorteile der erfindungsgemäßen Rundwebmaschine gegenüber herkömmlichen Rundwebmaschinen ergibt sich, wenn der Webschützen die Spulenachse der Schussbändchenspule im Wesentlichen im rechten Winkel auf die die geometrischen Verbindungslinien zwischen den Kettbändchen-Führungselementen und dem Webring enthaltende Fläche hält.An optimization of the mentioned advantages of the circular loom according to the invention over conventional looms results when the weaver the coil axis of the weft ribbon spool substantially at right angles to the holds geometric connecting lines between the warp tape guide elements and the web ring containing surface.

Bei einer Ausführungsform der erfindungsgemäßen Rundwebmaschine bildet die genannte Fläche im Wesentlichen eine Kreisringfläche.In one embodiment of the circular loom according to the invention, said surface essentially forms a circular ring surface.

Bei einer alternativen Ausführungsform der erfindungsgemäßen Rundwebmaschine bildet die genannte Fläche im Wesentlichen eine Kegelstumpffläche, deren Achse die Maschinenachse ist.In an alternative embodiment of the circular loom according to the invention, said surface substantially forms a frustoconical surface whose axis is the machine axis.

Um eine Schussbändchenspule so durch das Webfach führen zu können, dass ihre Spulenachse in einer Winkelstellung, die maximal +/- 15°, bevorzugt maximal +/- 10°, von einer Normalen auf die die geometrischen Verbindungslinien zwischen den Kettbändchen-Führungselementen und dem Webring enthaltende Fläche abweicht, am bevorzugtesten im Wesentlichen orthogonal auf diese Fläche steht, ist eine geeignete Spulenform zu wählen. Verglichen mit bei herkömmlichen Rundwebmaschinen verwendeten Schussbändchenspulen gleicher Bändchengesamtlänge wird vorgeschlagen, bei den zur Verwendung in der erfindungsgemäßen Rundwebmaschine vorgesehenen Schussbändchenspulen die Spulenlänge (häufig auch als Wickelbreite bezeichnet) zu reduzieren und den Spulendurchmesser zu erhöhen. Es wird eine Schussbändchenspule vorgeschlagen, bei der im vollen Zustand der Spulendurchmesser größer ist als die Spulenlänge, wodurch der verfügbare Raum im Webfach optimal ausgenützt werden kann. Durch diese erfindungsgemäße Spulenform wird die Masse der Spule verringert und eine zusätzliche Reduktion der Webschützenmasse (Eigengewicht, Leergewicht) erreicht. Die jeweilige Gewichtsreduktion der Spule und des Webschützen führt zu einer maßgeblichen Reduktion der Fliehkraft, die bei der Rotation der Webschützen auf die Bauelemente wirkt.In order to be able to guide a weft ribbon spool through the shed so that its coil axis in an angular position, the maximum +/- 15 °, preferably a maximum of +/- 10 °, from a normal to the geometric connecting lines between the Kettbändchen guide elements and the Webring deviating surface, most preferably is substantially orthogonal to this surface, a suitable coil shape is to be selected. Compared with weft ribbon spools of the same overall ribbon length used in conventional circular looms, it is proposed to reduce the spool length (often also referred to as spool width) in the weft ribbon spools intended for use in the circular loom according to the invention and to increase the spool diameter. It is a Schussbändchenspule proposed in the full state of the bobbin diameter is greater than the coil length, whereby the available space in the shed can be optimally utilized. By this coil shape according to the invention, the mass of the coil is reduced and achieved an additional reduction of the weaver mass (dead weight, dead weight). The respective weight reduction of the coil and the shuttle leads to a significant reduction of the centrifugal force, which acts on the components during rotation of the shuttle.

Durch die vorgeschlagene Spulenform ist es möglich, den erforderlichen Fachhub (Abstand der Umkehrpunkte der beiden Kettbändchenscharen voneinander) zu verkleinern und die Querbeschleunigung der Kettbändchen beim Fachwechsel zu verringern, was zu einer reduzierten Belastung der Webfachbildungseinrichtungen führt.By the proposed coil shape, it is possible to reduce the required shedding stroke (distance between the reversal points of the two Kettbändchenscharen each other) and to reduce the lateral acceleration of Kettbändchen when changing subjects, resulting in a reduced burden of shingles.

Weiters wird durch den kleineren Fachhub der Ausgleichsweg von Kettbändchen-Längenausgleichskompensatoren zwischen offenem und geschlossenem Webfach verringert, wodurch die Unterschiede der auf die Kettbändchen wirkenden Bändchenspannungen zwischen offenem und geschlossenem Webfach der Kettbändchen verkleinert und somit auch die Belastung der Kettbändchen und der Kompensatoren reduziert wird.Furthermore, the compensating path of warp length compensation compensators between the open and closed shed is reduced by the smaller shed, whereby the differences in the tape tension between the open and closed shed of the warp tapes acting on the warp tape and thus reduces the burden of Kettbändchen and compensators is reduced.

Die Erfindung wird nun anhand von Ausführungsbeispielen unter Bezugnahme auf die Zeichnungen näher erläutert. In den Zeichnungen zeigen:

The invention will now be explained in more detail by means of embodiments with reference to the drawings. In the drawings show:
  • Fig. 1 a schematic sectional view of a first embodiment of a circular loom according to the invention;
  • Fig. 2 a schematic perspective view of Rundriets and circulating in Rundriet Webschützen the circular loom of Fig. 1 ; and
  • Fig. 3 a schematic sectional view of a second embodiment of a circular loom according to the invention.

Fig. 1 und Fig. 2 zeigen schematisch und zur besseren Übersicht nicht maßstabsgetreu die für die Erfindung wesentlichen Elemente einer ersten Ausführungsform einer erfindungsgemäßen Rundwebmaschine 1. Die Rundwebmaschine 1 weist eine Vielzahl von Kettbändchen-Führungselementen 2 auf, die als Längenausgleichskompensatoren ausgebildet sind, die jeweils einen Federstab und eine Öse am oberen Ende des Federstabs zum Hindurchführen und Umlenken eines Kettbändchens 3 umfassen. Die Kettbändchen-Führungselemente 2 sind verteilt um das Rundriet 4 der Rundwebmaschine 1 herum angeordnet. Das Rundriet 4 umfasst einen oberen Reifen 4a und einen unteren Reifen 4b, zwischen denen gleichmäßig verteilt eine Vielzahl von Rietstäben 4c mit Zwischenräumen 4d zwischen benachbarten Rietstäben 4c angeordnet sind. Die Kettbändchen 3 werden von nicht dargestellten Kettbändchenspulen durch die Kettbändchen-Führungselemente 2 hindurch und weiter durch die Zwischenräume 4d zwischen den Rietstäben 4c hindurch geführt. Fig. 1 and Fig. 2 show schematically and for clarity not to scale essential to the invention elements of a first embodiment of a circular loom according to the invention 1. The circular loom 1 has a plurality of warp-tape guide elements 2, which are designed as length compensation compensators, each having a spring rod and an eyelet at the top End of the spring rod for passing and deflecting a Kettbändchens 3 include. The warp-tape guide elements 2 are arranged distributed around the round pile 4 of the circular loom 1 around. The round reed 4 comprises an upper hoop 4a and a lower hoop 4b, between which a plurality of reed bars 4c are uniformly distributed with spaces 4d between adjacent reed bars 4c. The warp strips 3 are guided by warp spools (not shown) through the warp-tape guiding elements 2 and further through the interspaces 4d between the reeding rods 4c.

Zwischen den Kettbändchen-Führungselementen 2 und dem Rundriet 4 sind um das Rundriet 4 herum verteilt Fachbildungseinrichtungen 5 angeordnet. Die Fachbildungseinrichtungen 5 umfassen eine Vielzahl erster Litzen 6 und eine Vielzahl zweiter Litzen 7, die an ihren Enden miteinander verbunden sind und eine obere Rolle 8a sowie eine untere Rolle 8b umschlingen. Jede der ersten Litzen 6 weist eine Öse 6a auf, durch die ein Kettbändchen 3 hindurchgeführt ist. Diese durch die Ösen 6a der ersten Litzen 6 hindurchgeführten Kettbändchen bilden eine erste Kettbändchenschar 10. Jede der zweiten Litzen 7 weist eine Öse 7a auf, durch die ein Kettbändchen 3 hindurchgeführt ist. Diese durch die Ösen 7a der zweiten Litzen 7 hindurchgeführten Kettbändchen bilden eine zweite Kettbändchenschar 11. Zumindest eine der oberen Rolle 8a und/oder der unteren Rolle 8b wird abwechselnd in eine erste und eine entgegengesetzte zweite Drehrichtung gedreht, wodurch die sie umschlingenden Litzen 6, 7 wechselweise nach oben und unten bewegt werden. Dadurch wird den beiden Kettbändchenscharen 10, 11 eine zueinander entgegengesetzte Wechselbewegung nach oben bzw. unten verliehen, wodurch das Webfach 9 (auch Wanderfach genannt) geöffnet und geschlossen wird. Das Webfach 9 bildet im geöffneten Zustand einen von den beiden Kettbändchenscharen 10, 11 definierten Raum, in dem sich ein Webschützen 12, der eine Schussbändchenspule 13 trägt, auf einer Kreisbahn entlang des Rundriets 4 bewegt und dabei ein nicht dargestelltes Schussbändchen von der von ihm getragenen Schussbändchenspule 13 abzieht und in das Webfach 9 einträgt. Das Webfach 9 ist geschlossen, wenn sich die Litzen 6, 7 in einer Mittelstellung befinden, in der die Ösen 6a, 7a der ersten Litzen 6 und der zweiten Litzen 7 auf gleicher Höhe sind, wodurch beide Kettbändchenscharen 10, 11 in derselben Fläche 9a liegen bzw. gemeinsam diese Fläche 9a aufspannen. In anderen Worten ist die Fläche 9a des geschlossenen Webfachs 9 die Winkelhalbierende zwischen der ersten Kettfadenschar 10, die in Fig. 1 die obere Kettfadenschar ist, und der zweiten Kettfadenschar 11, die in Fig. 2 die untere Kettfadenschar ist. Es gilt somit dass der Winkel α1 zwischen erster Kettfadenschar 10 und der Fläche 9a gleich dem Winkel α2 zwischen zweiter Kettfadenschar 10 und der Fläche 9a ist. Die Fläche 9a ist gleichzeitig als jene Fläche definiert, die die geometrischen Verbindungslinien zwischen den Kettbändchen-Führungselementen 2 und dem Webring 15 enthält.Between the warp-tape guiding elements 2 and the round pile 4, shedding devices 5 are arranged around the round pile 4. The shedding means 5 comprise a plurality of first strands 6 and a plurality of second strands 7 connected together at their ends and looped around an upper roller 8a and a lower roller 8b. Each of the first strands 6 has an eyelet 6a, through which a warp tape 3 is passed. These warp tapes passed through the eyelets 6a of the first strands 6 form a first warp thread 10. Each of the second strands 7 has an eyelet 7a through which a warp tape 3 is passed. These warp tapes passed through the eyelets 7a of the second strands 7 form a second warp sheet pile 11. At least one of the upper roll 8a and / or the lower roll 8b is rotated alternately in a first and an opposite second direction of rotation, whereby the stranding wires 6, 7 are alternately moved up and down. As a result, the two Kettbändchenscharen 10, 11 is given a mutually opposite reciprocal movement up or down, whereby the shed 9 (also called moving compartment) is opened and closed. The shed 9 forms in the open state one of the two Kettbändchenscharen 10, 11 defined space in which a shuttle 12, which carries a Schussbändchenspule 13, moves on a circular path along the Rundriets 4 while a not shown Schussbändchen of the worn by him Draws off ribbon weft coil 13 and enters into the shed 9. The shed 9 is closed when the strands 6, 7 are in a middle position in which the eyelets 6a, 7a of the first strands 6 and the second strands 7 are at the same height, whereby both Kettbändchenscharen 10, 11 lie in the same surface 9a or together span this surface 9a. In other words, the surface 9 a of the closed shed 9 is the bisecting line between the first warp thread 10, which in Fig. 1 the upper warp sheet is, and the second Kettfadenschar 11, the in Fig. 2 the lower warp sheet is. It is therefore the case that the angle α1 between the first warp thread 10 and the surface 9a is equal to the angle α2 between the second warp thread 10 and the surface 9a. The surface 9a is defined at the same time as the surface containing the geometric connecting lines between the warp-knitting guide members 2 and the weaving ring 15.

Die Größe des von den beiden Kettbändchenscharen 10, 11 definierten Raumes des Webfachs 9 ändert sich ständig mit der gegenläufigen Bewegung der beiden Kettbändchenscharen 10, 11, beginnend bei Null bei geschlossenem Webfach. Der Raum des Webfachs 9 erreicht ein Maximum, wenn sich die beiden Kettbändchenscharen 10, 11 an den entgegengesetzten Umkehrpunkten ihrer gegenläufigen Wechselbewegung befinden, wie in Fig. 1 dargestellt. An diesen Umkehrpunkten beginnt der so genannte Fachwechsel durch Umkehr der den gegenläufigen Kettbändchenscharen 10, 11 verliehenen Bewegung. Durch den Fachwechsel wird das zuletzt in das Webfach 9 eingetragene Schussbändchen im Gewebe fixiert, und es kann vom nächsten Schützen 12 das nächste Schussbändchen in das Webfach eingetragen werden. Wie in Fig. 2 zu sehen, laufen mehrere Webschützen 12 in gleichen Abständen voneinander im Rundriet 4 um. Das erzeugte schlauchförmige Gewebe 14 wird nach innen zu einem zentral angeordneten Webring 15 geführt, an dem es zu Abzugsrollen 16 hin umgelenkt wird.The size of the space defined by the two Kettbändchenscharen 10, 11 space of the shed 9 changes constantly with the opposite movement of the two Kettbändchenscharen 10, 11, starting at zero with a closed shed. The space of the shed 9 reaches a maximum when the two Kettbändchenscharen 10, 11 are at the opposite reversal points of their reciprocal change movement, as in Fig. 1 shown. At these points of reversal, the so-called change of subject begins by reversing the movement imparted to the opposing warp bands 10, 11. By changing the tray the last entered in the shed 9 Schussbändchen is fixed in the tissue, and it can be entered by the next shooter 12, the next weft ribbon in the shed. As in Fig. 2 To see several weavers walk 12 at equal intervals from each other in Rundriet 4. The generated tubular fabric 14 is guided inwardly to a centrally located Webring 15, where it is deflected to take-off rollers 16 out.

Gemäß der Erfindung hält der Webschützen 12 mittels einer Spulenhalterung 12b die Spulenachse 13a der Schussbändchenspule 13 in einer Winkelstellung β, die maximal +/-15°, bevorzugt maximal +/- 10°, von einer Normalen auf die Fläche 9a des geschlossenen Webfaches 9 abweicht. In der Ausführungsform der Rundwebmaschine gemäß Fig. 1 hält der Webschützen 12 die Spulenachse 13a der Schussbändchenspule 13 im rechten Winkel auf die Fläche 9a des geschlossenen Webfaches 9. Die Fläche 9a des geschlossenen Webfaches 9 bildet eine Kreisringfläche.According to the invention, the shuttle 12 holds by means of a coil holder 12b the coil axis 13a of the weft ribbon spool 13 in an angular position β which is at most +/- 15 °, preferably a maximum of +/- 10 °, deviates from a normal to the surface 9a of the closed shed 9. In the embodiment of the circular loom according to Fig. 1 holds the shuttle 12, the spool axis 13a of the weft ribbon spool 13 at right angles to the surface 9a of the closed shed 9. The surface 9a of the closed shed 9 forms a circular ring surface.

Die Rundwebmaschine 1 ist für die Verwendung von Kunststoffbändchen als Kettbändchen und Schussbändchen konzipiert, wobei die Kunststoffbändchen zur Erreichung höherer Festigkeit gereckt sind. Damit die Vorzüge der erfindungsgemäßen Rundwebmaschine voll zur Geltung kommen, wird ein Schussbändchenspulen-Typ verwendet, der im Vergleich zu bei herkömmlichen Schussbändchenspulen modifiziert ist, indem die Spulenlänge L reduziert ist und der Spulendurchmesser D erhöht ist. Im vollen Zustand der Schussbändchenspule 13 ist ihr Spulendurchmesser D größer ist als die Spulenlänge L, wodurch der verfügbare Raum im Webfach 9 optimal ausgenützt werden kann. Durch diese Spulenform kann der Webschützen 12 kürzer gebaut werden, was zu einer Reduktion seiner Masse führt. Da bei der vorgeschlagenen Spulenform der Spulenkern 13b kürzer und somit leichter sein kann, ist auch die Schussbändchenspule 13 leichter. Die jeweilige Gewichtsreduktion der Spule 13 und des Webschützen 12 führt zu einer maßgeblichen Reduktion der Fliehkraft, die bei der Rotation der Webschützen 12 auf die Stützrollen 12a, das Rundriet 4 und andere Bauelemente wirkt.The circular loom 1 is designed for the use of plastic tapes as Kettbändchen and Schussbändchen, wherein the plastic tapes are stretched to achieve higher strength. So that the advantages of the circular loom according to the invention come to full advantage, a Schussbändchenspulen-type is used, which is modified compared to conventional weft ribbon coils by the coil length L is reduced and the coil diameter D is increased. In the full state of the weft ribbon spool 13, its spool diameter D is larger than the spool length L, whereby the available space in the shed 9 can be optimally utilized. By this coil shape of the shuttle 12 can be built shorter, resulting in a reduction of its mass. Since in the proposed coil form of the spool core 13b can be shorter and thus lighter, and the weft ribbon spool 13 is lighter. The respective weight reduction of the spool 13 and the shuttle 12 leads to a significant reduction of the centrifugal force, which acts on the rotation of the shuttle 12 on the support rollers 12a, the Rundriet 4 and other components.

Durch die vorgeschlagene Spulenform ist es möglich, den benötigten Fachhub zu verkleinern, was eine Verkürzung der Rietstäbe 4c zur Folge hat. Kürzere Rietstäbe 4c verursachen im Gegensatz zu längeren Rietstäben weniger durch Schwingungen der Stäbe verursachten Lärm. Eine weitere Lärmreduktion kann durch die Reduktion der Drehzahl und die geringere Umlaufgeschwindigkeit der Webschützen 12 erzielt werden. Ein weiterer Vorteil der neuen Spulenform, im Vergleich zu langen Spulen mit geringem Durchmesser, ist der geringere Volumenverlust durch den Spulenkern im Verhältnis zum Gesamtvolumen der Spule.Due to the proposed coil shape, it is possible to reduce the required shed stroke, which has a shortening of the reed rods 4c result. Shorter reed rods 4c, unlike longer reed rods, cause less noise due to rod vibration. A further reduction in noise can be achieved by reducing the speed and the lower rotational speed of the shuttle 12. Another advantage of the new coil design, compared to long, small diameter coils, is the lower volume loss through the coil core relative to the overall volume of the coil.

Durch die höhere Schusszahl der beschriebenen Rundwebmaschine 1 werden weniger Webstühle für die gleiche Produktionsmenge an Gewebe benötigt, was den Platzbedarf in den Produktionsstätten verringert.Due to the higher number of shots of the circular loom 1 described less looms are needed for the same production amount of tissue, which reduces the space required in the production facilities.

Fig. 3 zeigt eine zweite Ausführungsform einer erfindungsgemäßen Rundwebmaschine 1' schematisch in Seitenansicht. Diese zweite Ausführungsform der Rundwebmaschine 1' unterscheidet sich von der in den Figuren 1 und 2 gezeigten ersten Ausführungsform nur insofern, als der Webring 15 höher positioniert ist als die Kettbändchen-Führungselemente 2, wodurch der Verlauf der ersten Kettbändchenschar 10 und der zweiten Kettbändchenschar 11 zur zentralen Maschinenachse 17 hin schräg nach oben geneigt ist. Deshalb ist auch das Webfach 9 entsprechend geneigt. Daraus ergibt sich, dass die Fläche 9a' des geschlossenen Webfaches 9 eine Kegelstumpffläche mit der Maschinenachse 17 als Kegelstumpfachse bildet. Auch das Rundriet 4' ist in diesem Ausführungsbeispiel als sich nach oben erweiternder Kegelstumpf ausgebildet. Die übrigen Bauteile der Rundwebmaschine 1' in ihrer zweiten Ausführungsform entsprechen jenen der ersten Ausführungsform und sind durch die gleichen Bezugszeichen bezeichnet. Zur Beschreibung dieser Bauteile sei auf die obigen Ausführungen verwiesen. Fig. 3 shows a second embodiment of a circular loom 1 'according to the invention schematically in side view. This second embodiment of the circular loom 1 'differs from that in the FIGS. 1 and 2 shown first embodiment only insofar as the Webring 15 is positioned higher than the Kettbändchen guide elements 2, whereby the course of the first Kettbändchenschar 10 and the second Kettbändchenschar 11 is inclined to the central machine axis 17 obliquely upwards. Therefore, the shed 9 is inclined accordingly. It follows that the surface 9a 'of the closed shed 9 forms a frustoconical surface with the machine axis 17 as a truncated cone axis. Also, the Rundriet 4 'is formed in this embodiment as upwardly widening truncated cone. The other components of the circular loom 1 'in its second embodiment correspond to those of the first embodiment and are designated by the same reference numerals. For a description of these components, reference is made to the above statements.
