Abstract

The invention relates to a textile web made of woven or knitted fabric which includes essentially longitudinally processed continuous mixed fiber or bi-component threads in relation to the course of the web, with a first type of fiber which forms the substantial portion of the threads or loops running in the direction of the web and which can be thermoplastically formed or separated at a first raised temperature, and with a second type of fiber which forms a smaller part of the threads or loops running in the direction of the web and is essentially structurally unchangeable during the first raised temperature. The invention also relates to a process including a first process step (preseparation) after the weaving or knitting process wherein the fibers of the first type of fibers are thermoplastically separated by heating a section of the web lying crosswise to the course of the web, and in a second process step (final separation) preceding further processing and/or final use, the fibers of the second type of fiber are separated in that section previously subjected to thermoplastic separation. The process of the final separation can be manually accomplished in a simple manner, whereby the cost for separation of the web into individual pieces is considerably reduced.

Description

Die Erfindung betrifft textiles Bahnmaterial aus Gewebe oder Gewirk, das in Bezug zum Bahnverlauf im wesentlichen längs verarbeitete durchgehende Fäden umfaßt und das zur Weiterverarbeitung und/oder zum Endverbrauch im wesentlichen quer zum Bahnverlauf in Einzelstücke trennbar ist und ein Verfahren zur Darstellung von vorkonfektionierten oder fertigkonfektionierten Einzelstücken aus Gewebe oder Gewirk, insbesondere von Bekleidungsstücken oder Teilen von Bekleidungsstücken sowie vorkonfektionierte oder fertigkonfektionierte Einzelstücke aus Gewebe oder Gewirk, die aus erfindungsgemäßem Bahnmaterial oder nach dem erfindungsgemäßen Verfahren dargestellt sind.The invention relates to textile web material made of woven or knitted fabric which, in relation to the web course, comprises continuous threads processed longitudinally and which can be separated into individual pieces for further processing and / or end use, essentially transversely to the web course, and to a method for producing pre-assembled or ready-made individual pieces made of woven or knitted fabric, in particular of clothing or parts of clothing and pre-assembled or ready-made individual pieces made of woven or knitted fabric, which are made from web material according to the invention or by the method according to the invention.

Das Anwendungsgebiet der Erfindung bezieht sich auf sämtliche Gebiete der Textilerzeugung, bei denen aus fortlaufendem Bahnmaterial vorkonfektionierte oder fertigkonfektionierte Einzelstücke, insbesondere Bekleidungsstücke hergestellt werden. Hauptsächlich erscheint dabei eine Anwendung im Bereich der Wirk- oder Raschelware, bei der der Konfektionierungsvorgang bei der Herstellung bereits weit fortgeschritten ist, als besonders vorteilhaft. Eine Anwendung im Bereich der Weberzeugnisse ist jedoch ebenso zu verwirklichen.The field of application of the invention relates to all areas of textile production in which pre-assembled or finished individual items, in particular clothing items, are produced from continuous web material. Mainly, an application in the area of knitted or Raschel goods, in which the manufacturing process in the manufacture is already well advanced, appears to be particularly advantageous. However, an application in the field of woven products can also be realized.

Nach einem bisher bekannten Verfahren wird fertiggewirktes Bahnmaterial endlos auf Rollen gewickelt oder in Kartons eingefüllt und später andernorts, ggfls. nach einer Zwischenbehandlung des Bahnmaterials zu Einzelstücken abgetrennt. Ursprünglich wurde dieser Trennvorgang rein manuell durch Zerschneiden quer zur Bahnrichtung durchgeführt, wobei ein erheblicher Lohnkostenanteil anfiel. Es sind inzwischen automatische Vorrichtungen bekannt, die das aufgewikkelte oder gefaltete Material einziehen und selbsttätig gesteuert die vorgesehenen Einzelstücke abtrennen. Auch dieses Verfahren ist noch zu aufwendig, da kalkulatorisch der Schneidelohn in der gleichen Größenordnung wie der Wirklohn liegt, wobei beide zusammengenommen in der Größenordnung der Materialkosten liegen.According to a previously known method, finished web material is wound endlessly on rolls or filled into boxes and later elsewhere, if necessary. separated into individual pieces after an intermediate treatment of the web material. Originally, this separation process was carried out purely manually by cutting transversely to the web direction, with a considerable proportion of labor costs. In the meantime, automatic devices are known which draw in the wound or folded material and automatically separate the intended individual pieces. This method is also still too complex, since the cutting wage is calculated in the same order of magnitude as the real wage, both taken together in the order of the material costs.

Der Erfindung liegt die Aufgabe zugrunde, ein neuartiges Erzeugnis und ein an dieses angepaßtes Verfahren vorzuschlagen, mittels derer das Trennen von textilem Bahnmaterial in vorkonfektionierte oder fertigkonfektionierte Einzelstücke vereinfacht und verbilligt werden kann, ohne daß Nachteile in der Handhabung der Erzeugnisse bei der Weiterverarbeitung oder beim Transport in Kauf zu nehmen sind.The invention has for its object to propose a novel product and a method adapted to this, by means of which the separation of textile web material into pre-assembled or ready-made individual pieces can be simplified and cheaper, without disadvantages in the handling of the products during further processing or transport to be accepted.

Die Lösung besteht in einem Bahnmaterial, das durch eine erste Faserart, die den wesentlichen Anteil der in Bahnrichtung verlaufenden Fäden oder Maschen bildet und bei einer ersten erhöhten Temperatur thermoplastisch umformbar und trennbar ist, und durch eine zweite Faserart, die einen geringen Anteil der in Bahnrichtung verlaufenden Fäden oder Maschen bildet und bei der ersten erhöhten Temperatur im wesentlichen strukturell unveränderlich ist, gekennzeichnet ist, sowie in einem Verfahren, das sich dadurch auszeichnet, daß in einem ersten, dem Web- oder Wirkvorgang nachgeschalteten Verfahrensschritt die Fasern der ersten, thermoplastisch umformbaren Faserart durch Erhitzung in einer quer zum Bahnverlauf liegenden Patie getrennt werden und daß in einem zweiten, einer Weiterver- . arbeitung und/oder dem Endverbrauch vorgeschalteten Verfahrensschritt die thermisch widerstandsfähigeren Fasern der zweiten Faserart in der zuvor der thermoplastischen Trennung unterzogenen, quer zum Bahnverlauf liegenden Patie getrennt werden.The solution consists of a web material which is formed by a first type of fiber, which forms the major part of the threads or stitches running in the web direction, and can be thermoformed and separated at a first elevated temperature, and by a second type of fiber, which forms a small proportion of the web direction running threads or stitches and is essentially structurally unchangeable at the first elevated temperature, is characterized, and in a process that characterized in that in a first process step following the weaving or knitting process, the fibers of the first, thermoplastically deformable type of fiber are separated by heating in a patient lying transversely to the path of the web, and in a second, further processing. work and / or the process step upstream of the end use, the more thermally resistant fibers of the second type of fiber are separated in the patient previously subjected to the thermoplastic separation and lying transversely to the path of the web.

Hiermit ergibt sich die Möglichkeit, in einem dem Herstellungsprozeß des Bahnmaterials unmittelbar nachgeschalteten und mit diesem zusammen gesteuerten Vortrennungsverfahrenschritt die thermoplastisch umformbaren Faseranteile des Bahnmaterials zu durchtrennen, während die thermisch widerstandsfähigeren Faseranteile unzerstört bleiben und den Zusammenhalt des Bahnmaterials bewerkstelligen. Der Anteil und die Dimensionierung der verbindenden Faserteile soll dabei imstande sein, sämtliche beim Weitertransport oder der Weiterverarbeitung auftretenden Längskräfte im Bahnmaterial zerstörungsfrei aufzunehmen. Hiermit ist gewährleistet, daß sämtliche nachgeschalteten Verfahrensschritte und Förderschritte in unveränderter Art durchgeführt werden können, während der endgültige Fertigtrennungsvorgang, der beispielsweise beim Verbraucher unmittelbar vor der Benutzung erfolgen kann, erheblich erleichtert ist und etwa durch Aufbringen einer kurzzeitig erhöhten Zugkraft, insbesondere durch manuelles Abreißen erfolgen können soll. Hierbei sind jedoch auch derartige Abwandlungen eingeschlossen, bei denen das Abtrennen beispielsweise unter Inanspruchnahme einer Schneidkante oder eines anderen Schneidwerkzeuges vollzogen wird, da in jedem Fall die Trennstelle vorgezeichnet ist und nur wenige, leicht durchtrennbare Tragfäden umfaßt, während die Schmelzfäden bereits vorher an der Schnittstelle thermoplastisch getrennt worden sind. Selbstverständlich besteht auch die Möglichkeit, auch die Tragfäden je nach Material durch thermoplastisches Umformen oder durch thermisches Durchbrennen mit einem manuell handhabbaren Werkzeug oder einer fest installierten Vorrichtung zu teilen, wofür durch die Durchtrennung der Schmelzfäden im ersten Verfahrensschritt ebenffalls eine Erleichterung geschaffen ist, so daß der Fertigtrennvorgang schneller erfolgen kann.This results in the possibility, in a pre-separation process step directly downstream of the production process of the web material and controlled together with it, to cut through the thermoplastically deformable fiber parts of the web material, while the thermally more resistant fiber parts remain undestroyed and bring about the cohesion of the web material. The proportion and the dimensioning of the connecting fiber parts should be able to absorb all the longitudinal forces occurring in the web material during further transport or further processing without destruction. This ensures that all subsequent process steps and conveying steps can be carried out in an unchanged manner, while the final separation process, which can be carried out immediately before use, for example, by the consumer, is considerably easier and can be done, for example, by applying a briefly increased tensile force, in particular by manual tearing should be able to. However, modifications are also included here in which the cutting is carried out, for example, using a cutting edge or another cutting tool, since in each case the separation point is pre-drawn and includes only a few, easily severable supporting threads, while the melt threads have already been thermoplastic separated at the interface. Of course, there is also the possibility, depending on the material, of dividing the supporting threads by thermoplastic forming or by thermal burning with a manually manageable tool or a permanently installed device, for which a relief is also created by cutting through the melt threads in the first process step, so that the Finished separation process can be done faster.

Grundsätzlich ist daran gedacht, die im wesentlichen längs verarbeiteten Fäden zum Teil als Schmelzfäden aus einem thermoplastisch umformbaren Material, wie beispielsweise Polyester darzustellen und einen bestimmten Anteil oder eine bestimmte Anzahl von Tragfäden aus einem thermisch widerstandsfähigeren Material wie beispielsweise einer Naturfaser vorzusehen. Die Erfindung erstreckt sich jedoch auch auf die Möglichkeit, alle verarbeiteten Fäden oder einen Teil davon aus einem Anteil thermoplastisch umformbarer Fasern und einem Anteil thermisch widerstandsfähigerer Fasern zu spinnen oder zu ziehen, so daß nach dem ersten Schritt der thermischen Vortrennung nur ein Anteil der so aufgebauten Fäden, insbesondere z.B. ein Kernbeich als tragender Bestandteil bestehen bleibt, der später erleichtert durchtrennbar ist. Für die thermisch widerstandsfähige Faserart bzw. den damit hergestellten Fadenkern kommen beispielsweise auch Glas- oder Kohlefasern in Frage. Als geeignetes Material für den hitzebeständigen Anteil der Fasern hat sich das Erzeugnis Nomex (Markenname Dupont) herausgestellt, dessen Schmelzpunkt bei ca. 420 Grad Celsius liegt. Bei Einwirkung eines rotglühenden Hitzedrahtes von ca. 1.300 Grad Celsius für eine Zeitdauer von 10 sec. erweisen sich die Polyamidfasern als beständig. Für die weitere Handhabung des Bahnmaterials erscheint es sinnvoll, zumindest zwei Tragfäden vorzusehen, die bevorzugt im Kantenbereich der Bahn angeordnet sein sollten. Abwandlungen in der Zahl und der Anordnung der Tragfäden richten sich im wesentlichen nach den Materialstärken und sind stets unter den bereits genannten Gesichtspunkten zu sehen, daß eine gute Handhabung des Bahnmaterials und eine leichte Durchtrennbarkeit zu Einzelstücken in gleicher Weise gegeben sein soll.Basically, it is contemplated to present the essentially longitudinally processed threads in part as melt threads made of a thermoplastic material such as polyester and to provide a certain proportion or a certain number of supporting threads made of a more thermally resistant material such as a natural fiber. However, the invention also extends to the possibility of spinning or drawing all processed threads or a part thereof from a portion of thermoplastically deformable fibers and a portion of thermally more resistant fibers, so that after the first step of the thermal pre-separation, only a portion of the fibers thus constructed Threads, in particular, for example, a core area remains as a load-bearing component, which can later be severed more easily. Glass or carbon fibers, for example, are also suitable for the thermally resistant fiber type or the thread core produced therewith. The product Nomex (brand name Dupont) has proven to be a suitable material for the heat-resistant portion of the fibers, whose melting point is around 420 degrees Celsius. When exposed to a red-hot wire of approx. 1,300 degrees Celsius for a period of 10 seconds, the polyamide fibers prove to be resistant. For the further handling of the web material, it seems sensible to provide at least two supporting threads, which should preferably be arranged in the edge region of the web. Variations in the number and arrangement of the carrying threads depend essentially on the material thicknesses and can always be seen from the points already mentioned that good handling of the web material and easy separability to individual pieces should be given in the same way.

Die Anwendung der Erfindung ist nicht auf einlagiges Bahnmaterial beschränkt, sondern erstreckt sich auch auf doppellagiges Gewirk, das entsprechend dem Verwendungszweck der abzutrennenden Einzelstücke z.B. als vorkonfektionierte Bekleidungsstücke in Form von Hosen, Strumpfhosen, Trikots oder dergleichen längs der Kanten und/oder in Querrichtung miteinander verwirkt sein kann oder längs verlaufende Auftrennungen aufweisen kann. In bevorzugter Weise sind dabei die vorgesehenen Trennstellen optisch und/oder mechanisch erfaßbar und bei doppellagiger Wirkweise bevorzugt in einlagigen Partien angeordnet.The application of the invention is not limited to single-ply web material, but also extends to double-ply knitted fabric which, e.g., according to the intended use of the individual pieces to be separated, as pre-assembled items of clothing in the form of trousers, tights, jerseys or the like can be knitted together along the edges and / or in the transverse direction or can have longitudinal separations. The separation points provided can preferably be detected optically and / or mechanically and, in the case of a double-layer mode of operation, are preferably arranged in single-layer parts.

Ein bevorzugter Anwendungsfall bezieht sich auf Bahnmaterial, aus dem elastische Höschen gemäß dem deutschen Patent Nr. P 30 04 469 darstellbar sind. Bei diesen liegen die Beinöffnungen in einem Kantenbereich und die Körperöffnung im anderen Kantenbereich des Bahnmaterials und seitliche Nähte werden durch quer zur Bahnrichtung verlaufende ineinander gewirkte Partien dargestellt, die zugleich als optisch und mechanisch erfaßbare Bereiche zur Fertigtrennung bzw. zur Vortrennung vorgesehen sind. Durch periodisches Ineinanderwirken einer Kante auf kurzen Abschnitten wird dabei der Zwickel des Höschens gebildet. Der genannte Anwendungsfall stellt ein Beispiel dar, bei dem durch den Vorgang der Fertigtrennung in Einzelstücke ein fertigkonfektioniertes Erzeugnis entsteht, das seiner Verwendung beispielsweise im medizinischen Bereich zugeführt werden kann. Mit der erfindungsgemäßen Vortrennung kann das Bahnmaterial in geeigneter Weise verpackt, beispielsweise auf Spulen aufgewickelt werden oder in gefältelter Form in Kartons verpackt werden, ohne daß Handhabungs- oder Transportprobleme entstehen, und beim Endverbraucher je nach Bedarf einzeln mit kurzem Ruck vom Bahnmaterial abgerissen werden. Mit dem Aufwickeln auf Spulen kann eine wesentlich vergrößerte Packungsdichte erzielt werden, wodurch sich der Tranportraum verringert und damit Transportkosten reduzieren lassen.A preferred application relates to sheet material from which elastic panties can be produced according to German Patent No. P 30 04 469. In these, the leg openings are located in one edge area and the body opening in the other edge area of the web material and side seams are represented by interwoven parts running transversely to the web direction, which are at the same time provided as optically and mechanically detectable areas for pre-separation or pre-separation. The gusset of the panties is formed by periodically interacting an edge on short sections. The use case mentioned represents an example in which the finished separation into individual pieces results in a finished product which can be used, for example, in the medical field. With the pre-separation according to the invention, the web material can be packaged in a suitable manner, for example wound up on spools or packed in cardboard boxes in crumpled form without handling or transport problems, and can be torn off from the web material individually by the end user with a short jerk as required. With the winding on spools, a significantly increased packing density can be achieved, whereby the transport space is reduced and thus transportation costs can be reduced.

Nach einem anderen Anwendungsbeispiel werden aus zweilagigem Bahnmaterial vorkonfektionierte Strumpfhosen gebildet, bei denen der Beinverlauf sich jedoch in Bahnlängsrichtung erstreckt. Die Beine entstehen hierbei durch längsgerichtete periodische Auftrennung des doppellagigen Materials, wobei zugleich die entsprechenden Längskanten miteinander verwirkt werden. Da derartig vorkonfektionierte Strumpfhosen im Fußbereich und gegebenenfalls auch im Bundbereich noch weiter bearbeitet werden müssen, ist durch das anwendhngsgemäße Verfahren insbesondere der Weitertransport und die Weiterverarbeitung erleichtert, da das erfindungsgemäße Bahnmaterial automatisch verpackt und transportiert und in weiteren Bearbeitungsstationen endlos eingezogen werden kann. Die Trennung wird jedoch auch hier erfindungsgemäß vorbereitet und kann auch hier automatisch oder manuell in einem letzten erleichterten Verfahrensschritt erfolgen.According to another application example, prefabricated tights are formed from two-ply web material, but the legs run in the longitudinal direction of the web. The legs are created by lengthwise periodic separation of the double-layer material, whereby the corresponding longitudinal edges are also interlocked. Since such prefabricated tights have to be processed further in the foot area and possibly also in the waist area, the application-specific method in particular facilitates further transport and further processing, since the web material according to the invention can be automatically packaged and transported and endlessly drawn in further processing stations. However, the separation is also prepared according to the invention here and can also take place automatically or manually in a last, simplified process step.

Das erfindungsgemäße Verfahren läuft in der Weise ab, daß unmittelbar nach dem Web- oder Wirkvorgang in einem der Vortrennung dienenden Schritt mittels einer geeigneten Vorrichtung sämtliche thermoplastischen Faseranteile einer bei relativ niedrigen Temperatur umformbaren Art in periodischer Abfolge quer zur Bahnrichtung durch Erhitzen und damit bewirktes Durchschmelzen getrennt werden und in einem zweiten Verfahrensschritt, der bevorzugt mechanisch durch Zugbelastung ausgeführt wird, die endgültige Durchtrennung in vorkonfektionierte oder fertigkonfektionierte Einzelstücke durch Trennen der restlichen, unbeeinflußt gebliebenen Faseranteile einer zweiten Art erfolgt. Unter besonderen Umständen kann auch die Fertigtrennung z.B. bei einer höheren Temperatur auf der Grundlage thermoplastischer Umformung erfolgen. Dies kann beispielsweise sinnvoll sein, um jeweils nach einer größeren Anzahl von Einzelstücken eine bestimmte Länge von Bahnmaterial abzutrennen, um sie transportfähig oder verpackungs- oder vertriebsfähig zu machen. In sinnvoller und bevorzugter Weise ist die Vorrichtung zur Vortrennung mit der Wirkvorrichtung zusammen oder in Abhängigkeit von dieser gesteuert. Dies gilt selbstverständlich auch für die mögliche Vorrichtung zur Fertigtrennung.The process according to the invention proceeds in such a way that, immediately after the weaving or knitting process, in a pre-separation step by means of a suitable device, all of the thermoplastic fiber components contribute to one relatively low temperature formable in a periodic sequence transversely to the web direction by heating and thus causing melting and in a second process step, which is preferably carried out mechanically by tensile stress, the final separation into pre-assembled or ready-made individual pieces by separating the remaining, unaffected fiber portions of a second type. In special circumstances, the final separation can take place, for example, at a higher temperature on the basis of thermoplastic forming. This can be useful, for example, in order to cut off a certain length of web material after a large number of individual pieces, in order to make them transportable or packable or distributable. In a sensible and preferred manner, the device for pre-separation is controlled together with or dependent on the knitting device. Of course, this also applies to the possible device for finished separation.

Geeignete Vorrichtungen, mit denen der Vortrennvorgang durchgeführt werden kann, sind bekannt und können beispielsweise einen einfachen Heizdraht, ein durch eine eingebaute Spule erhitztes Schneidwerkzeug oder dergleichen umfassen, wobei das Trennwerkzeug und das Bahnmaterial relativ zueinander annäherbar sein müssen. Die Art der Weiterbearbeitung sowie der Transportschritte richtet sich ganz nach der Art des herzustellenden Erzeugnisses. Die Vorteile der Erfindung werden dabei stets in höchsten Maße ausgeschöpft, wenn der endgültige Trennvorgang durch rein manuelle Zugbelastung erfolgen kann und zum fertigkonfektionierten Produkt führt.Suitable devices with which the pre-separation process can be carried out are known and can comprise, for example, a simple heating wire, a cutting tool heated by a built-in coil or the like, the separating tool and the web material having to be approachable relative to one another. The type of further processing and the transport steps depend entirely on the type of product to be manufactured. The advantages of the invention are always exploited to the greatest extent if the final separation process can be carried out by purely manual tensile stress and leads to the finished product.

In Fig. 1 ist eine doppellagige Bahn 1 aus gewirktem Material dargestellt, die aus einzelnen vorkonfektionierten elastischen Höschen 2a bis 2c gebildet wird. Die einzelnen Höschen werden durch optisch oder mechanisch erfaßbare Trennpartien 3a bis 3d voneinander geteilt, in. denen das doppellagige Material zu einer Lage verwirkt ist und aus denen nach dem Trennen Seitennähte der Höschen entstehen. Die seitlichen Kanten der doppellagigen Bahn sind ausschließlich in den Kantenabschnitten 4a bis 4e miteinander verbunden, wodurch jeweils der Zwickel bzw. die Beinlöcher gebildet werden. Der gegenüberliegende Kantenbereich 5 ist unter Verwendung von gummielastischen Fäden gewirkt und bildet damit nach dem Trennen der Einzelstücke jeweils einen elastischen Bund.In Fig. 1, a double-layered web 1 made of knitted material is shown, which is formed from individual pre-assembled elastic panties 2a to 2c. The individual panties are divided from one another by optically or mechanically detectable separating parts 3a to 3d, in which the double-layer material is forged into one layer and from which side seams of the panties arise after the separation. The lateral edges of the double-layered web are connected to one another exclusively in the edge sections 4a to 4e, as a result of which the gusset or the leg holes are formed in each case. The opposite edge region 5 is knitted using rubber-elastic threads and thus forms an elastic waistband after the individual pieces have been separated.

In Fig. 2 ist ebenfalls eine doppellagige Bahn 6 aus textilem Material dargestellt, die aus einzelnen Vorprodukten für elastische Strumpfhosen gebildet ist, die im wesentlichen in Bahnlängsrichtung liegen. Die aufeinanderliegenden Lagen sind längs ihrer gesamten Kantenbereiche 7, 8 miteinander verbunden, insbesondere miteinander verwirkt. Jeweils periodisch sind längs verlaufende Auftrennungen 9 vorgesehen, längs deren Begrenzung die beiden Lagen ebenfalls vollständig miteinander verbunden sind. In dieser Weise bilden die Kanten 7 und 8 Außennähte und die Kanten längs der Auftrennung 9 Innennähte der herzustellenden Strumpfhosen. In dieser Weise bildet sich ein Rumpfabschnitt 10 und Beinabschnitte 11, 12 von vorkonfektionierten Strumpfhosen 15. Beispielhaft sind periodisch unregelmäßig angeordnete Trennpartien dargestellt, wobei die Trennpartien 13a, 13b im Bereich der Beinabschnitte und die Trennpartien 14a, 14b im Bereich der Rumpfabschnitte liegen. Hierdurch kann je nach der Art des weiteren Fertigungsablaufes und der Fertigkonfektionierung die Fertigtrennung in zwei Phasen vorgesehen sein, wobei ein Verschnittanteil entsteht.2 also shows a double-layered web 6 made of textile material, which is formed from individual preliminary products for elastic tights, which essentially lie in the longitudinal direction of the web. The layers lying one on top of the other are connected to one another along their entire edge regions 7, 8, in particular interlocked with one another. Periodic separations 9 are provided periodically, along the boundary of which the two layers are also completely connected to one another. In this way, the edges 7 and 8 form outer seams and the edges along the separation 9 form inner seams of the tights to be produced. In this way, a torso section 10 and leg sections 11, 12 of pre-assembled tights 15 are formed. For example, periodically irregularly arranged separating parts are shown, the separating parts 13a, 13b lying in the area of the leg sections and the separating parts 14a, 14b in the area of the trunk sections. In this way, depending on the type of the further production process and the finished assembly, the finished separation can be provided in two phases, with a waste portion being produced.

In Fig. 3 ist ein Ausschnitt aus einem Gewirk im Bereich einer Trennpartie dargestellt, wobei mit 16 ein thermisch widerstandsfähiger Tragfaden und mit 17 a bis e thermoplastisch umformbare Schmelzfäden dargestellt sind. Insgesamt ist das intakte Gewebe nach dem Wirken gezeigt, während an der durch einen Pfeil gekennzeichneten Stelle das Ergebnis der Vortrennung erkennbar ist, bei dem die Schmelzfäden zerstört sind und der Tragfaden unverändert ist.3 shows a detail from a knitted fabric in the region of a separating section, 16 being a thermally resistant supporting thread and 17 a to e being thermoplastic deformable melt threads. Overall, the intact tissue is shown after it has been knitted, while the result of the preliminary separation, in which the enamel threads are destroyed and the carrying thread is unchanged, can be seen at the point indicated by an arrow.

In Fig 4 ist wiederum ein Gewirkausschnitt nach dem Wirkvorgang mit einer durch einen Pfeil gekennzeichneten Stelle nach dem ersten Verfahrensschritt dargestellt. Sämtliche Fäden 18 a bis d sind von gleichartiger Struktur und haben sowohl thermisch umformbare Faseranteile als auch thermisch widerstandsfähige Faseranteile, insbesondere in ihrem Kernbereich. Nach dem ersten Verfahrensschritt der Vortrennung sind längs einer Trennlinie in jedem Faden der Anteil der ersten Faserart weggeschmolzen, während der Anteil der thermisch widerstandsfähigeren Faseranteile weiterhin trägt und insgesamt die Bahn zusammenhält, der die üblichen beim Weitertransport und der Weiterverarbeitung auftretenden Zugbelastungen zerstörungsfrei aufnehmen kann.4 again shows a knitted section after the knitting process with a point indicated by an arrow after the first method step. All threads 18 a to d are of the same structure and have both thermally deformable fiber components and thermal resistant fiber components, especially in their core area. After the first process step of pre-separation, the portion of the first fiber type has melted away along a dividing line in each thread, while the portion of the thermally more resistant fiber portions continues to hold and holds together the web, which can absorb the usual tensile loads occurring during further transport and further processing without destruction.

In Fig. 5 ist ein Gewirk mit im Detail gezeigter Struktur dargestellt, bei dem ein Tragfaden 16 und Schmelzfäden 17 erkennbar sind.5 shows a knitted fabric with a structure shown in detail, in which a supporting thread 16 and melt threads 17 can be seen.
