Die Neuerung betrifft einen Sack und dergleichen Verpakkiangsmittel. Bei diesen Säcken können vorzugsweise Gewebe von äusserst geringer Dicke sowie Elemente aus Erzeugnissen verwendet und mit einer Nab.t verbunden werden, wobei diese Erzeugnisse unter Anwendung anderer Verfahrenstechniken hergestellt werden, wie z. B. ungewebte, geleimte odergepresste Fa.3erwaren, Virkwaren und nach dem "Malimo"-Verfahren hergestellte Erzeugnisse.The innovation relates to a sack and the like packaging means. In these sacks, fabrics of extremely small thickness and elements made from products can preferably be used used and connected to a Nab.t, this Products are manufactured using other process technologies, such as B. unwoven, glued or pressed Fa.3erwaren, Virkwaren and according to the "Malimo" process manufactured products.

Bas Verbinden von Textilerzeugnissen während ihrer Herstellu erfolgt meist mit Hilfe einer Naht. Je nach dem Bestimmungszweck des Erzeugnisses werdet an die Naht verschiedene Anforderungen gestellt. In Gewebeerzeugnissen, z.B. Säcken, Schonern, Beuteln usw. muss die Naht vor- allem hohe Kräfte t tragen,die um 50% und mehr die Festigkeit des Gewebes, aus r die Ware erzeugt ist,überschreiten,d.h.,die Kraft,die erforc lieh ist,um einen Streifen zu zerreissen,der aus zwei in dej Mitte mittels einer Naht verbundenen Teilen besteht,muss z\ The joining of textile products during their manufacture is usually done with the help of a seam. Depending on the intended purpose of the product, different requirements are placed on the seam. In fabric products such as sacks, protectors, pouches, etc., the seam must bear high forces t which exceed the strength of the fabric from which the goods are made by 50% or more, ie the force required is to tear a strip, which consists of two parts connected in the middle by means of a seam, z \

gleich sein der Kraft, die notig ist, um einen analogen Streifen zu zerreißen, der aus einem einheitlichen Gewebe herausgeschnitten wurde. Bei anderen Erzeugnissen als Säcken, z.B. bei Zelten oder Planen wird von der Bäht äußer der Festigkeit, eine vollständige Dichtigkeit gefordert.equal to the force required to tear an analogous strip cut from a uniform tissue. For products other than sacks, e.g. for Camping or tarpaulin is made of the baht outside of the strength, one complete tightness required.

Bisher wiesen die Nähte bei den oben erwähnten Erzeugnissen seist Überlappungen der Enden beider zu verbindender Erzeugaisteile für den Nähvorgang auf.So far, the seams in the above-mentioned products have been overlapping the ends of the two product parts to be connected for the sewing process.

Der größte Nachteil der bisherigen Textilerzeugnisse und Nähte bestand darin, daß sie den gestellten Anforderungen nicht in -»ollem Maße genügten. In aus Gewehen von geringer Dichte (z.B. für Säcke) erzeugten Waren konnte die unentbehrliche Festigkeit der Naht und damit der Textilerzeugnisse nur mit größter Schwierigkeit erhalten werden. Falls die Erzeugnisse durch parallel snr Naht "Linie verlaufende Kräfte beansprucht werden, fransen die Kettfaden aus der Naht bzw. der Schußfaden aus dem Hand eines der verbundenen Gewebeteile aus. Erfolglos blieben Nähte, die entweder auf einem mehrmaligen Falzen (TTmrollen) der Kanten beider zu verbindender Teilstücke vor dem Nähen, oder auf der Herstellung der Naht unter Anwendung von zwischen die beiden zu verbindenden Gewebeteile eingelegten Textilborten beruhen. Beim Verbinden von Geweben größerer Dichte wurde zwar kein Ausfraneen der Kett- oder Schußfäden beobachtet, die Festigkeit der Naht blieb aber weiterhin gering. Als Folgeerscheinung wurden die Gewebe fäden durch die Maschinennadel während des Nähvorgangs verschoben oder zerschnitten. Da die Festigkeit eines je- -den Erzeugnisses durch die Festigkeit seines schwächsten Teiles bestimmt wird, hatten fertige Säcke aufgrund der Mangel aller bekannten Nähte immer eine geringere Festigkeit als das Gewebe, aus dem sie hergestellt waren. Zwar ist bei der Fertigung von Erzeugnissen aus Geweben von größerer Dichte leichter eine Naht von größerer Festigkeit zu erhalten, aber auch bei diesen Er-The main disadvantage of previous textile products and seams consisted in the fact that they did not fully meet the requirements. In from low density contractions (e.g. for sacks), the indispensable strength of the seam and thus of the textile products could only be maintained with great difficulty. If the products go through in parallel snr seam "line running forces are stressed, fray the warp thread from the seam or the weft thread from the hand of one of the connected fabric parts. Seams remained unsuccessful, either on a multiple folding (TTmrolling) of the edges of both parts to be connected before sewing, or on the Production of the seam based on the use of textile braids inserted between the two pieces of fabric to be connected. At the When joining fabrics of greater density, no fraying of the warp or weft threads was observed, the strength of the But seam remained small. As a consequence, the fabric threads were shifted or cut by the machine needle during the sewing process. Since the strength of each -the product is determined by the strength of its weakest part, had finished sacks due to the lack of all Known seams always have a lower strength than the fabric from which they were made. Although it is in the production of It is easier for products made from fabrics of greater density to obtain a seam of greater strength, but even with these

«eugnissen konnte nicht immer die geforderte Nahtfestigkeit •rsielt werden.The required seam strength could not always be rsielt eugnissen ".

Bekannt ist allgemein die Tatsache, daß bei Konfektionserzeugnissen aus Geweben von hoher Dichte, um die Festigkeit der Verbindung der einzelnen Erzeugnisteile zu erhöhen, wie s.B. das Auflegen der Taschen auf Hosen, nicht durch Nähen, sondern durch Nieten erfolgt, was letztlich sogar zu einer Modeerscheinung geworden ist.It is generally known that in ready-made products made of high-density fabrics, in order to increase the strength of the connection between the individual product parts, such as placing the pockets on trousers, not by sewing but by riveting, which ultimately even became a fad has become.

In Erzeugnissen wie Zelten bildet außer den durch die geringe Hahtfestigkeit der bekannten Nahte hervorgerufenen Unbequemlichkeiten den größten Nachteil die Tatsache, daß durch die nach bekannter Art erzeugten Nähte bei der Benutzung der Zelte Undichtigkeiten auftreten. Um diesen Nachteil auszuschalten bsw. zu umgehen, sind die Nähte der Zelte mit speziellen Appreturen versehen. Da derartige Appreturen aber während der Benutzung des Zeltes schnell abbröckeln, sind Vasserlecke bei allen Zeltnähten und Zeltverbindungsstellen eine allgemein bekannte Tatsache.In products such as tents, the main drawback is other than caused by the low Hahtfestigkeit seams of the known inconveniences to the fact that leaks occur due to the generated in a known manner seams during use of the tent. To avoid this disadvantage bsw. To avoid this, the seams of the tents are provided with special finishes. However, since such finishes crumble off quickly during the use of the tent, water leaks are a well-known fact in all tent seams and tent connection points.

Eine noch geringere Festigkeit weisen die bis jetzt bekannten übernähten Nähte bei Textilerzeugnissen aus ungewebten, geleimten oder gepreßten Faserwaren, aus Wirkwaren, oder nach dem •Malimo"- oder auch "Hasche!"-Verfahren hergestellte auf. Insbesondere ist die Festigkeit der bisherigen übernähten Nähte bei den letzten zwei Verfahrenstechniken infolge der besonderen Lage des Fadens im Erzeugnis äußerst gering. Dieser Nachteil ist umso schwerwiegender, als aufgrund der höheren Festigkeit der ■it diesen Verfahrenstechniken hergestellten Textilerzeugnissen eine immer größere Menge an "Geweben" für die Fertigung von Sacken nach diesen Verfahrenstechniken verwendet werden. Unter der Bezeichnung "Gewebe" wird ein Halbprodukt verstanden, aus dem verschiedene Textilerzeugnisse, z.B. Säcke oder andere Verpackungsmittel gefertigt werden. Zur Vereinfachung wird im fol-The hitherto known over-sewn seams in textile products made of non-woven, glued fabric have an even lower strength or pressed fiber goods, from knitted goods, or manufactured according to the • Malimo "or" Hasche! "process. In particular is the strength of the previously over-sewn seams in the last two process technologies due to the special The position of the thread in the product is extremely small. This disadvantage is all the more serious than due to the higher strength of the ■ Textile products manufactured using these process technologies an increasing amount of "fabrics" for the manufacture of Sacks can be used according to these processing techniques. The term "fabric" is understood to mean a semi-finished product various textile products, e.g. bags or other packaging are manufactured. To simplify matters, the following

genden das Wort "Gewebe11 für flache Erzeugnisse in Form von Tafeln oder Bändern angewendet, und zwar unabhängig davon, ob •s eich um Gewebe, Wirkwaren, ungewebte geleimte oder gepreßte faserwaren, oder auch um nach dem "Malimo"- oder "fiascnei"-Yerfehren hergestellte Erzeugnisse handelt.The word "fabric 11 is used for flat products in the form of panels or ribbons, regardless of whether • it relates to fabrics, knitwear, non-woven glued or pressed fiber goods, or according to the" Malimo "or" fiascnei " -Yerfehren manufactured products.

Außer dem Nähen sind auch noch andere Möglichkeiten zum Verbinden von Textilien bekannt. Bekannt ist zum Beispiel eine Verbindung, die auf dem Verleimen der Ränder der zu verbindenden Teilstucke, entweder durch das Auftragen von Leim, oder eines Klebebandes beruht. Dies ermöglicht ziemlich hohe Nahtfestigkeiten, doch unterliegt diese Festigkeit unter Einwirkung von Feuchtigkeit einer beträchtlichen Verringerung, weswegen alle auf diese Art und Weise erzeugten Verpackungen (Säcke) weder im Straßen- und Seeverkehr noch unter tropischen Verhältnissen, ■lLbü praktisch nirgends, verwendet werden können, überdies eig-Mf sich dies nicht zur Herstsiltu?1? von Verpackungen sus Gegeben von geringer Dichte bzw. für ^rE?i?ugnisse nach der "Raschel"-Verfahrenstechnik, oder aus wabenartigen Wirkwaren, da in diesen Fällen auch ohne Einwirkung der Witterungsverhältnisse die Nahtfestigkeit äußerst gering ist.In addition to sewing, other ways of joining textiles are also known. For example, a connection is known which is based on gluing the edges of the parts to be connected, either by applying glue or an adhesive tape. This enables fairly high seam strengths, but this strength is subject to a considerable reduction under the influence of moisture, which is why all packaging (sacks) produced in this way cannot be used either in road or sea transport or under tropical conditions, practically nowhere, moreover, is this not a matter of manufacture? 1 ? of packaging sus given of low density or for ^ rE? i? ug according to the "Raschel" process technology, or of honeycomb-like knitted goods, since in these cases the seam strength is extremely low even without the influence of weather conditions.

Bekannt ist auch eine Naht oder Verbindung für Textilerzeugnisse, die darauf beruht, daß die zu verbindenden Teile zunächst «inen Überzug aus Gummi oder Kunststoff bzw. aus synthetischen Mitteln erhalten. In diesen Fällen binden lediglich die Belag-Substanzen, das Gewebe selbst bleibt nicht gebunden, wodurch die Festigkeit der Naht nur auf der Haftfestigkeit des Überzuges beruht. Diese Methode findet keine Anwendung bei Verpackungen, fur die wabenartige Gewebe oder Gewirke bzw. Gewebe nach anderen Verfahrenstechniken gefordert werden, da die Herstellung der Überzüge bei derartigen Strukturen beinahe unmöglich ist and überdies die Ausführung von Verpackungen sinnlos wäre, weil die äußerst geringe Dichte durch den Erhalt einer hohen Luftdsrculässigkeit bediagt ist und jeder überzug eine VerringerungA seam or connection for textile products is also known, which is based on the fact that the parts to be connected initially “A coating made of rubber or plastic or made of synthetic materials. In these cases, only the coating substances bind, the tissue itself does not remain bound, which means the strength of the seam is based only on the adhesive strength of the coating. This method is not used for packaging, for the honeycomb-like fabric or knitted fabric or fabric according to other process technologies are required, since the production the coating is almost impossible with such structures and, moreover, the implementation of packaging would be pointless, because the extremely low density is due to the maintenance of a high air permeability and each coating a reduction

Alle oben erwähnten Nachteile der Säcke mit den bekannten Nähten oder Verbindungen von Erzeugnissen geringer Dichte können durch die neuerunssgemässen Sack« und dgl. Textil erzeugnisse, behoben werden. Die Aufgabenstellung zur Vermeidung der Nachteile der bisher erzeugten Säcke und dgl. besteht in der Schaffung derartiger Säcke, bei deren Nähten weder ein Ausfransen der Kett- und Schussfäden aus den Rändern der" zu verbindenden Teile noch ein Zerschneiden durch die Maschinennadel der zum Verbinden bestimmten Teile erfolgt.All of the above mentioned disadvantages of the bags with the known seams or joints of low density products can through the new bags and similar textile products, be resolved.

Band 3 des zweiten Gewebe element es aufgesetzt. Auf den Hand 3 let ein oberer Streifen 4 aus Thermoplast gelegt. Nach dem Aufeinanderlegen aller Nahtelemente wird von unten eine untere Elektrode 8 und von oben eine obere Elektrode 2 aufgesetzt. Die Elektroden werden bei gleichzeitiger Einwirkung der zur Plastifizierung der Thermoplaststreifen erforderlichen, mittels Generatoren 1 und 9 erzeugten Wärme, aufeinander gedrückt. Durch die Wärmeeinwirkung bei gleichzeitigem Druck werden alle Streifen zu einem Band 10 verschmolzen.Band 3 of the second fabric element put it on. On hand 3 let put an upper strip 4 made of thermoplastic. After Placing all of the seam elements on top of one another, a lower electrode 8 is placed from below and an upper electrode 2 is placed from above. With the simultaneous action of the necessary for plasticizing the thermoplastic strips, the electrodes are by means of Generators 1 and 9 generated heat, pressed together. Due to the effect of heat with simultaneous pressure, all Strips fused to form a band 10.

Hie Naht besitzt die Gestalt eines Bandes aus Thermoplaste, in das alle Rand elemente beider zu verbindender Gewebeteile eingeschmolzen sind. Durchgeführte Versuche zeigten, daß eine neuerungsgemäße Naht eine Festigkeit aufweist, die gleich und oft sogar hoher ist als die Festigkeit des Gewebes, aus dem das mit einer derartigen Naht verbundene Erzeugnis hergestellt wurde. Die Wasserdurehiässigkeit einer derartigen Naht ist immer niedriger als die Wasserdurchlässigkeit des mit dieser Naht verbundenen Gewebes, sogar dann, wenn das Gewebe vor der Verarbeitung appretiert wurde. Die hohe Wasserfestigkeit "ändert sich wahrend der Benutzung des Erzeugnisses nicht.This seam is in the form of a thermoplastic ribbon, in that all edge elements of both tissue parts to be connected are melted down. Tests carried out showed that an innovation according to Seam has a strength that is the same and often even higher than the strength of the fabric from which it is such a seam connected product was made. The water permeability of such a seam is always lower than the water permeability of the fabric connected to this seam, even if the fabric is prior to processing was finished. The high water resistance "does not change during the use of the product.

Um die hohe Festigkeit der erfindungsgemäßen Naht nachzuweisen, wurden Laborprüfungen über die Zerreißfestigkeit von mit solchen Nähten verbundene Streifen vorgenommen* Zum Vergleich gleichartiger Gewebe, wurde ein einheitlicher, aus dem gleichen Gewebe ausgeschnittener, nichtverbundender Streifen sowie ein aus zwei Hälften auf bekannte Weise zusammengenähter Streifen und schließlich ein aus zwei Teilen bestehender, neuerungsge- »äß verbündender Streifen Zerreißfestigkeitsproben unterzogen.To prove the high strength of the seam according to the invention, Laboratory tests were carried out on the tensile strength of strips connected to such seams * For comparison similar tissue, became a unitary, non-connecting strip cut from the same tissue as well as a of two halves sewn together in the known way and finally a two-part, innovative »Subjected to tensile strength tests according to the connecting strip.

DLe Neuerung kanu nickt nur bei der Ausführung von Nahten, sondern auch bei der Verstärkung von Geweberändern bei solchen Erzeugnissen wie Säcken und Zelten angewendet werden. TTm einem Ausfransen der Fäden aus den Geweberändern, insbesondere bei geschnittenen Geweben vorzubeugen, wurde nach bekannten Verfahren der Sand einige Male gerollt (gefalzt) und dann eist auf einer Nähmaschine genäht. Bei den neuerungsgemäßen Textilerzeugnissea bzw. der neuerungsgemäßen Naht ist der Geweberand Tsrstarkt, indes auf den unteren Streifen 6 der Eand des Gewebes aufgelegt und auf den Oberteil des Geweberandes der obere Streifen 4 aus Thermoplast aufgesetzt ist, wonach durch den Druck der Elektroden 8 und 2 von oben nach unten unter gleichseitiger Wärmeeinwirkung die Thermoplaste verschmolzen wurden.The innovation Kanu nods only when sewing seams, They can also be used to reinforce the edges of fabrics in such products as sacks and tents. TTm To prevent the threads from fraying out of the fabric edges, in particular in the case of cut fabrics, was known according to the prior art Process the sand rolled (folded) a few times and then sewn on a sewing machine. In the case of textile products according to the innovation a or the seam according to the innovation is the fabric edge Tsrstarkt, while on the lower strip 6 the edge of the fabric placed and on the upper part of the fabric edge of the upper strip 4 made of thermoplastic is placed, after which through the Pressure of the electrodes 8 and 2 from top to bottom under the same effect of heat, the thermoplastics were fused.
