Description

Verfahren und Einrichtung zur Herstellung textiler netzartiger Flächen¬ gebildeProcess and device for the production of textile net-like flat structures
Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Herstel¬ lung textiler netzartiger Flächengebilde nach verschiedenen Verfesti¬ gungsverfahren, beispielsweise dem Ketten- oder Nähwirkverfahren.The invention relates to a method and a device for the manufacture of textile net-like fabrics by various consolidation methods, for example the warp or sewing method.
In der Textilindustrie werden Netze üblicherweise mit bekannten Netz- knüft- bzw. -knotmaschinen mittels Knüpfhaken oder mit bekannten Ket¬ ten- bzw. Nähwirkmaschinen mittels Zungen- bzw. Schiebernadeln gefer¬ tigt. Nachteilig ist dabei, daß die Produktbreite durch die Arbeits¬ breite und die Netzöffnungsstruktur determiniert, die Strukturvariabi¬ lität stark durch die Verfahren eingegrenzt oder nur mit hohem Aufwand, wie bei dem kettengewirkten Netz mit im Randbereich variierter Netzma¬ schengröße, die den Einsatz mehrerer Legeschienen und die Variation der Legung erfordert (JP 51-57041), zu verwirklichen ist. Die Produkte sind infolge der Fadenanhäufungen im Knotenbereich und der daraus resultie¬ renden Scheuerempfindlichkeit sowie ihrer geringen Strukturvariabilität nur begrenzt einsetzbar.In the textile industry, nets are usually manufactured with known net knotting or knotting machines by means of knot hooks or with known warp or sewing machines by means of latch or slide needles. It is disadvantageous here that the product width is determined by the working width and the network opening structure, the structure variability is greatly limited by the method or only with great effort, as in the case of the warp-knitted network with a mesh size that varies in the edge region, which necessitates the use of several laying rails and the variation of the laying requires (JP 51-57041) to be realized. The products can only be used to a limited extent as a result of the thread accumulations in the knot area and the resulting abrasion sensitivity and their low structure variability.
Bekannt ist eine modifizierte Kettenwirkmaschine zur Verarbeitung von Kunststoffgarnen (DE 2706930) mit Parallelschußeintrag, wobei die Ver¬ bindung der Fäden mittels Schweißschwertern realisiert wird. Dabei ent- spricht die erzeugbare Produktbreite nur der Arbeitsbreite der Maschi¬ ne. Die Netzmaschengeometrie ist durch die festgelegte Arbeitsbreite und die Anordnung der verbindenden Elemente, der Schweißschwerter, de¬ terminiert. Desweiteren ist durch das gewählte Verfestigungsverfahren nur die Verarbeitung thermoplastischen Materials möglich, so daß das Produkt in seinen Anwendungsmöglichkeiten eingeschränkt ist.A modified warp knitting machine for processing plastic yarns (DE 2706930) with parallel weft insertion is known, the threads being connected by means of welding swords. The product width that can be generated corresponds only to the working width of the machine. The net mesh geometry is determined by the defined working width and the arrangement of the connecting elements, the welding swords. Furthermore, only the processing of thermoplastic material is possible due to the selected solidification process, so that the product is limited in its possible applications.
Es sind auch Nähwirkmaschinen bekannt, auf denen Quadratmaschennetze gefertigt werden können (DD 269298). Dabei werden quer zur Verarbei- tungsrichtung parallelliegende Schußfäden zugeführt und in der Ar- beitsstelle in bestimmten Abständen quer zur Verarbeitungsrichtung von Maschenstäbchenabschnitte bildenden Arbeitsorganen durchstochen und mittels kettfadenumschlingender Nähfäden angebunden bzw. eingebunden. Nachteilig ist dabei, daß nur Quadratmaschennetze mit durchgehenden Schuß- und Kettfäden realisierbar sind und die auch den Abstand zwi¬ schen den zugeführten Schußfäden bzw. den Abstand der maschenstäbchen- bildenden Arbeitsorgane untereinander bestimmte Größe der Netzöffnungen nur begrenzt und mit hohem Aufwand änderbar ist. Desweiteren ist die maximale Produktbreite gleich der Arbeitsbreite und die Festigkeit der Produkte ist bedingt durch die Tatsache, daß auch nicht an der Maschen¬ bildung beteiligte Spitzennadeln die Schußfadenvorlage anstechen, ge¬ ring.Sewing machines are also known on which square mesh networks can be produced (DD 269298). In this case, parallel weft threads are fed in transversely to the direction of processing and pierced at certain intervals in the work station transversely to the processing direction of work organs forming wale sticks and tied or bound in by means of sewing threads looping around the warp thread. The disadvantage here is that only square mesh networks with continuous weft and warp threads can be realized and that the size of the mesh openings, which is determined by the spacing between the supplied weft threads and the spacing of the wales forming work organs, is only limited and can be changed with great effort. Furthermore, the maximum product width is equal to the working width and the firmness of the products is due to the fact that tip needles not involved in the stitch formation pierce the weft thread template.
Aufgabe der Erfindung ist die Schaffung eines Verfahrens und einer Ein¬ richtung zur Durchführung des Verfahrens nach verschiedenen Verfesti¬ gungsverfahren, beispielsweise dem Ketten- oder Nähwirkverfahren, zur Herstellung textiler, netzartiger Flächengebilde mit großer Netzöff- nungsweite, hoher Strukturvariabilität und über die Arbeitsbreite hin¬ ausgehenden Produktbreiten.The object of the invention is to provide a method and a device for carrying out the method according to various consolidation methods, for example the warp or sewing method, for the production of textile, net-like flat structures with a large net opening width, high structural variability and across the working width outgoing product widths.

In den Figuren 1 bis 3 sind die erfindungsgemäßen Verfahrensschritte an Hand einer Nähwirkarbeitsstelle schematisch dargestellt. Der Nähwirk¬ arbeitsstelle werden die Netzschenkelfadengruppen 1, bestehend aus ei¬ nem Nähfaden 2, einem Stehschußfaden 3 und Funktionsfäden 4 in bekann¬ ter Weise zugeführt. Dabei entsteht durch Fransenlegung der Nähfäden 2 ein stabiler, aus einem Maschenstäbchen bestehender Netzöffnungsschen- kel in Verarbeitungsrichtung, wobei im Prozeß der Maschenbildung die bandförmigen Stehschußfäden 3 und die Funktionsfäden 4 durchstochen werden und der Funktionsfaden mit der Netzschenkelfadengruppe 1 verbun¬ den wird. Diese Bildung der Netzöffnungsschenkel in Verarbeitungsrich¬ tung kann in bekannter Weise durch das Weglassen der Stehschußfäden 3, durch die verbundene Anzahl der Maschenstäbchen im Netzmaschenschenkel und bei mehr als einem Maschenstäbchen im Netzmaschenschenkel durch eine andere Bindung der Nähfäden 2 variiert werden.In Figures 1 to 3, the method steps according to the invention are shown schematically using a sewing work station. The knitted net thread groups 1, consisting of a sewing thread 2, a standing weft thread 3 and functional threads 4, are fed to the sewing knitting unit in a known manner. The fraying of the sewing threads 2 results in a stable mesh opening leg consisting of a wale in the direction of processing, the band-shaped standing weft threads 3 and the functional threads 4 being pierced in the process of stitch formation and the functional thread being connected to the mesh leg thread group 1. This formation of the net opening legs in the processing direction can be done in a known manner by omitting the standing weft threads 3, by the connected number of wales in the net stitch leg and in the case of more than one wale in the mesh stitch leg can be varied by a different binding of the sewing threads 2.
Fig. 1 zeigt den Zeitpunkt, an dem während der Maschenbildung durch eine seitliche Versatzbewegung die Funktionsfäden 4 nach links aus dem Bereich der Netzschenkelfadengruppe 1 herausgeführt werden.1 shows the point in time at which the functional threads 4 are led out of the area of the net leg thread group 1 to the left during the stitch formation by a lateral offset movement.
In Fig. 2 ist gezeigt, daß die Unterlegung des Funktionsfadens 4 unter die benachbarte Schiebernadel und die Ausbildung der Funktionsfadenre- serven durch Auslenken der Funktionsfäden 4 in oder entgegen der Ver¬ arbeitungsrichtung und Bildung einer Schlaufe abgeschlossen ist. Die gebildeten Funktionsfadenreserven werden freigegeben und gleichzeitig an- bzw. eingebunden und so in der benachbarten Netzschenkelfadengruppe 1 fixiert. Als Funktionsfadenreserve wird dabei eine während der Ent- stehung eines textilen Netzes im Prozeß der Maschenbildung aufgebaute und durch die Überführung des textilen Produktes aus seiner Herstel¬ lungslage in die Gebrauchslage (Spreizen) aufhebbare, schlaufenförmige Fadenreserve im Funktionsfadensystem verstanden.2 shows that the placement of the functional thread 4 under the adjacent slide needle and the formation of the functional thread reserves is completed by deflecting the functional threads 4 in or against the direction of processing and forming a loop. The functional thread reserves formed are released and connected or integrated at the same time and thus fixed in the adjacent net thigh thread group 1. A functional thread reserve is understood to mean a loop-shaped thread reserve in the functional thread system which is built up during the formation of a textile network in the stitch formation process and which can be eliminated by transferring the textile product from its production position into the position of use (spreading).
Fig. 3 stellt die Bewegung in die Ausgangsstellung dar. Entsprechend der Netzmaschengeometrie erfolgt zu einem geeigneten Zeitpunkt wieder das Herausführen der Funktionsfäden 4 aus der Netzschenkelfadengruppe 1 und ein erneutes Bilden der Funktionsfadenreserve.3 shows the movement into the starting position. In accordance with the net mesh geometry, the functional threads 4 are again guided out of the net thigh thread group 1 at a suitable time and the functional thread reserve is formed again.
Der Funktionsfaden kann nach dem erfindungsgemäßen Verfahren in einer der nebenliegenden Netzschenkelfadengruppen oder in derselben Netz¬ schenkelfadengruppe an- bzw. eingebunden werden. Aus den Funktionsfäden können dabei quer und in Verarbeitungsrichtung keine und/oder gleiche und/oder unterschiedliche Funktionsfadenreserven gebildet werden. Die Einbringung der mit Funktionsfadenreserven versehenen Funktionsfäden in Verarbeitungsrichtung kann dabei rechtwinklig oder schräg zur Verarbei¬ tungsrichtung erfolgen, wobei unter rechtwinklig eine Einbindung im gleichen Arbeitszyklus und unter schräg eine Einbindung in einem der nächsten Arbeitszyklen verstanden wird. In Fig. 4 ist das nach dem Nähwirkverfahren hergestellte erfindungsge¬ mäße Produkt in Herstellungslage und in Fig. 5 in Gebrauchslage darge¬ stellt.According to the method according to the invention, the functional thread can be connected or bound in one of the adjacent network leg thread groups or in the same network leg thread group. In this case, no and / or the same and / or different functional thread reserves can be formed transversely and in the processing direction from the functional threads. The functional threads provided with functional thread reserves can be introduced in the processing direction at right angles or obliquely to the processing direction, with rectangular being understood to be an integration in the same work cycle and oblique an integration in one of the next work cycles. 4 shows the product according to the invention produced by the sewing process in the production position and in FIG. 5 in the position of use.
Fig. 4 zeigt, daß Stehschußfäden 3, Näh- und Funktionsfäden 2; 4 die Netzschenkelfadengruppen bilden und damit in der bereits beschriebenen Weise die Netzmaschenschenkel in Verarbeitungsrichtung. Die wechselwei¬ se in zwei benachbarten Netzschenkelfadengruppen an- oder eingebundenen Funktionsfäden bilden die Funktionsfadenreserven. Fig. 5 stellt das textile Netz in Gebrauchslage dar. Die Funktionsfadenreserven sind auf¬ gehoben, die Funktionsfäden sind ausgestreckt und bilden somit vorzugs¬ weise quer zur Verarbeitungsrichtung liegende Netzmaschenschenkel. Es ist erkennbar, daß zwischen der ersten und zweiten Netzschenkelfaden- gruppe 1.1; 1.2 der Funktionsfaden 4 in Verarbeitungsrichtung um einen abnehmenden Betrag ausgelenkt bzw. nicht ausgelenkt, d.h. unterschied¬ liche Funktionsfadenreserven gebildet, zwischen der zweiten und dritten Netzschenkelfadengruppe 1.2; 1.3 der Funktionsfaden um gleiche Beträge ausgelenkt, d.h. gleiche Funktionsfadenreserven gebildet und zwischen der dritten und vierten Netzschenkelfadengruppe 1.3; 1.4 nicht ausge¬ lenkt, d.h. keine Funktionsfadenreserven gebildet werden. Aus dieser Konstellation ergibt sich ein Produkt in Gebrauchslage wie es Fig. 5 zeigt.Fig. 4 shows that weft threads 3, sewing and functional threads 2; 4 form the net leg thread groups and thus the net stitch legs in the processing direction in the manner already described. The functional threads alternately connected or integrated in two adjacent network leg thread groups form the functional thread reserves. 5 shows the textile net in the position of use. The functional thread reserves are removed, the functional threads are stretched out and thus preferably form net mesh legs lying transversely to the processing direction. It can be seen that between the first and second network leg thread group 1.1; 1.2 the functional thread 4 is deflected or not deflected in the processing direction by a decreasing amount, i.e. different functional thread reserves formed, between the second and third reticulated thread group 1.2; 1.3 the functional thread is deflected by equal amounts, i.e. the same functional thread reserves formed and between the third and fourth reticulated thread group 1.3; 1.4 not deflected, i.e. no functional thread reserves are formed. This constellation results in a product in the position of use as shown in FIG. 5.

Rigid or jointly and / or group-wise and / or individually displaceable displacement elements, such as sinkers, latch or slide needles, grippers, etc., can also be used as functional thread reserve formation systems.
Nachfolgend wird die Wirkungsweise der erfindungsgemäßen Einrichtungen beschrieben. In den Figuren 1 bis 3 ist die Wirkungsweise der in den Figuren 8 und 9 gezeigten Ausführungsform eines Funktionsfadenreservebildungssystems 11 schematisch dargestellt. Der Nähwirkarbeitsstelle werden die Netzschen- kelfadengruppen 1, bestehend aus den Näh- 2, Stehschuß- 3 und Funk¬ tionsfäden 4 in bekannter Weise zugeführt. Dabei entsteht durch Fran¬ senlegung der Nähfäden 2 ein stabiler, aus einem Maschenstäbchen beste¬ hender Netzöffnungsschenkel in Verarbeitungsrichtung, wobei im Prozeß der Maschenbildung die bandförmigen Stehschußfäden 3 und die Funktions- fäden 4 von den Schiebernadeln 5 durchstochen werden können. Fig. 1 zeigt den Zeitpunkt, an dem während der Maschenbildung durch eine seit¬ liche Versatzbewegung der Funktionsfadenführer 8 die Funktionsfäden 4 nach links aus dem Bereich der Netzschenkelfadengruppe 1 herausgeführt werden. Die als nach unten geöffnete Hakennadeln 12 ausgebildeten Ele- mente zur Funktionsfadenreservebildung erfassen die Funktionsfäden 4, indem sie in Richtung der Lochnadeln 16 bewegt und ihre Hakenenden gleichzeitig durch eine Schwenkbewegung der gesamten Barre nach unten geklappt werden. Die Ausbildung der Funktionsfadenreserven muß dabei mit der Unterlegung des Funktionsfadens 4 unter die Schiebernadel 5 bzw. mit dem Anstechen des Funktionsfadens durch die Schiebernadel ab¬ geschlossen sein. In Fig. 2 ist die Unterlegung der Schiebernadeln 5 und die Ausbildung der Funktionsfadenreserven durch die Rückbewegung der Hakennadeln 12 abgeschlossen. Durch eine Schwenkbewegung der Barre nach oben werden die Funktionsfadenreserven freigegeben und gleichzei- tig durch die Schiebernadeln 5 an- bzw. eingebunden und so in der be¬ nachbarten Netzschenkelfadengruppe 1 fixiert. Fig. 3 stellt die Bewe¬ gung des Funktionsfadenreservebildungssystems 11 in Richtung der Schie¬ bernadelspitzen in die Ausgangsstellung dar. Entsprechend der Netzma¬ schengeometrie erfolgt zu einem geeigneten Zeitpunkt das Herausführen der Funktionsfäden 4 aus der Netzschenkelfadengruppe 1 nach rechts und ein erneutes Bilden der Funktionsfadenreserve durch das Funktionsfaden- reservebildungssystem 11.The mode of operation of the devices according to the invention is described below. The mode of operation of the embodiment of a functional thread reserve formation system 11 shown in FIGS. 8 and 9 is shown schematically in FIGS. 1 to 3. The net thigh thread groups 1, consisting of the sewing threads 2, standing weft threads 3 and functional threads 4 are fed to the sewing work station in a known manner. The laying of the sewing threads 2 results in a stable mesh opening leg consisting of a wale in the direction of processing, the band-shaped standing weft threads 3 and the functional threads 4 being able to be pierced by the pusher needles 5 in the process of stitch formation. 1 shows the point in time at which the functional threads 4 are led out of the area of the net leg thread group 1 to the left during the stitch formation by a lateral offset movement of the functional thread guides 8. The elements for the formation of the functional thread reserve, which are designed as hook needles 12 opened downward, capture the functional threads 4 by moving in the direction of the perforated needles 16 and their hook ends are simultaneously folded down by a pivoting movement of the entire bar. The formation of the functional thread reserves must be completed by placing the functional thread 4 under the slide needle 5 or by piercing the functional thread with the slide needle. In Fig. 2 the underlaying of the pusher needles 5 and the formation of the functional thread reserves are completed by the return movement of the hook needles 12. By pivoting the bar upwards, the functional thread reserves are released and at the same time connected or bound by the pusher needles 5 and thus fixed in the adjacent net leg thread group 1. 3 shows the movement of the functional thread reserve formation system 11 in the direction of the pusher needle tips into the starting position. According to the mesh stitch geometry, the functional threads 4 are led out to the right at a suitable time and the functional thread reserve is formed again the functional thread reserve formation system 11.
In Fig. 10 ist eine Kettenwirkarbeitsstelle mit erfindungsgemäßem Funk- tionsfadenreservebildungssystem 11 abgebildet. Die nebeneinander auf der Nadelbarre 6 in einer Reihe angeordneten Schiebernadeln 5 mit den ihnen zugeordneten Schließdrähten 7 bilden aus der mittels der Lochna- dein 16 zugeführten Netzschenkelfadengruppe 1 - bestehend aus den Kett¬ fäden 18 und den Funktionsfäden 4 - unter Mitwirkung der kombinierten Einschließ- und Abschlagplatinen 17 in bekannter Weise die Netzmaschen- schenke! in Verarbeitungsrichtung.10 shows a warp knitting work station with a functional thread reserve formation system 11 according to the invention. The slide needles 5 arranged side by side on the needle bar 6 in a row with the closing wires 7 assigned to them form from the Your 16 supplied net leg thread group 1 - consisting of the warp threads 18 and the functional threads 4 - with the cooperation of the combined inclusion and knock-off sinkers 17 in a known manner, the net mesh legs! in the processing direction.
Der Funktionsfaden 4 wird dabei im Netzmaschenschenkel angebunden. Er¬ findungsgemäß ist in der Kettenwirkarbeitsstelle ein mindestens zwi¬ schen zwei quer zur Verarbeitungsrichtung benachbarten Schiebernadeln 5 einwirkendes Funktionsfadenreservebildungssystem 11 angeordnet. Das Funktionsfadenreservebildungssystem 11 besteht aus den Hakennadeln 12 welche in einer Reihe nebeneinander auf der über die gesamte Breite der Maschine reichenden, horizontal verschiebbaren und um ihre Längsachse schwenkbaren Barre befestigt sind, die durch den Antrieb 13 bewegt wird, welchem eine Veränderungssteuerung 14 zugeordnet ist. Entspre¬ chend der Netzgeometrie wird der Funktionsfaden 4 durch die Lochnadel 16 aus der Netzschenkelfadengruppe 1 herausgeführt, durch die horizon¬ tale Bewegung der Barre mit den Haken adeln 12 in Richtung der Schie¬ bernadeln 5 und eine gleichzeitige Schwenkbewegung von oben nach unten von den Hakennadeln 12 erfaßt und durch die folgende Rückbewegung der Barre zur Funktionsfadenreserve kuliert. Anschließend wird der Funk¬ tionsfaden 4 in der nebenliegenden Netzschenkelfadengruppe 1 durch die Schiebernadel 5 an- bzw. eingebunden und die Funktionsfadenreserve durch eine Schwenkbewegung der Hakennadeln 12 von unten nach oben und eine horizontale Bewegung derselben in die Ausgangsposition abgeworfen.The functional thread 4 is tied in the mesh leg. According to the invention, a functional thread reserve formation system 11 is arranged in the warp knitting station at least between two pushpins 5 adjacent to the processing direction. The functional thread reserve formation system 11 consists of the hook needles 12 which are fastened in a row next to one another on the bar which extends over the entire width of the machine, is horizontally displaceable and can be pivoted about its longitudinal axis and is moved by the drive 13, to which a change control 14 is assigned. Corresponding to the network geometry, the functional thread 4 is led out of the network leg thread group 1 through the perforated needle 16, through the horizontal movement of the bar with the hook needles 12 in the direction of the slide needles 5 and a simultaneous swiveling movement from top to bottom of the hook needles 12 detected and cumulated by the subsequent return movement of the bar to the functional thread reserve. Subsequently, the functional thread 4 in the adjacent net thigh thread group 1 is tied or bound by the slide needle 5 and the functional thread reserve is thrown off into the starting position by a swiveling movement of the hook needles 12 from below and a horizontal movement thereof.
An Kettenwirk- oder Nähwirkarbeitsstellen mit zwei Nadelsystemen bzw. mit als Zungen- oder Spitzennadeln ausgebildeten Wirknadeln oder an Ketten- oder Nähwirkarbeitsstellen mit runder Arbeitsstelle ist die Erfindung gleichermaßen anwendbar.The invention is equally applicable to warp or sewing work stations with two needle systems or with knitting needles designed as tongue or point needles or at warp or sewing work stations with a round work station.
