Abstract

The edge of the first material layer (1) to be connected which is coated on one side with a thermosetting plastics is folded round 180 deg. by a mechanism (4) onto its uncoated surface. A strip (3) of thermosetting plastics coated on one side with a heat-reactive adhesive is folded lengthwise and brought with the adhesive-coated side to adjoin the uncoated sides of the turned-over edge of the first material layer (1). - The edge of the second material layer (2) is supplied with the coated side towards the coated side of the turned over edge of the first layer (1). The adhesive-coated strip (3) is then heated from the centre and the edges of the two material layers are heated between the coated sides wherein the edges and strip (3) are pressed together by a pair of pressure rollers (24, 25) ensuring continuous sticking and welding.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method according to the preamble of claim 1 and a device for Implementation of the procedure.

Wasserdichte Wetter-, Arbeitsschutz- und Sportbekleidung wird aus Gründen der Hautfreundlichkeit zur Vermeidung von Kondenswasserbildung beim Tragen vorwiegend aus einseitig mit thermoplastischem Kunststoff beschichteten Trägergeweben hergestellt. Bei der Zelt- und Schutzplanenherstellung sind Kostengründe für die Verwendung solcher Schichtgewebe maßgebend. Waterproof weather, work protection and sportswear are used for reasons of skin friendliness Avoidance of condensation when wearing, mainly made of one-sided thermoplastic material coated carrier fabrics. In the manufacture of tents and tarpaulins, there are cost reasons decisive for the use of such layered fabrics.

Zum Verbinden einseitig beschichteter Gewebelagen bei der Konfektionierung sind mehrere Verfahren bekannt. Several methods are known for joining fabric layers coated on one side during assembly.

Zunächst das Verbinden durch Nähen. Es wird durch die Naht zwar eine feste und dauerhafte Verbindung erzielt, jedoch geht dadurch der größte Vorteil beschichteter Gewebe, die absolute Waserdichtigkeit, verloren, so daß die Naht in einem zusätzlichen zeitaufwendigen und in der Wirkung unbefriedigenden Arbeitsgang nachträglich, beispielsweise durch Aufschweißen eines Abdeckbandes, abgedichtet werden muß.First the connection by sewing. The seam creates a firm and permanent connection achieved, but the greatest benefit is coated Fabric, the absolute watertightness, lost, so that the seam in an additional time-consuming and a subsequent operation with unsatisfactory effect, for example by welding a masking tape, must be sealed.

Die Verbindung kann auch durch Heizkeil-, Hochfrequenz- oder Heißgasschweißen hergestellt werden, indem die beschichteten Materialseiten miteinander verbunden werden.The connection can also be made by hot wedge, radio frequency or hot gas welding the coated sides of the material are connected to one another.

Obwohl diese an sich materialgerechte Verbindung in einem kontinuierlichen Arbeitsgang herstellbar ist, wird sie relativ selten verwendet, weil ihre Festigkeit durch die Haftung der Beschichtung auf dem Trägergewebe begrenzt ist und die Anforderungen in den verschiedenen Anwendungsgebieten meistens höher liegen. Darüber hinaus sind die Schnittkanten der Gewebelagen bei dieser Verbindung gegen Ausfransen nicht gesichert.Although this material-appropriate connection can be produced in a continuous operation, is they are used relatively seldom because their strength is due to the adhesion of the coating to the carrier fabric is limited and the requirements in the various areas of application are usually higher. About that In addition, the cut edges of the fabric layers are not secured against fraying in this connection.

Nach einem durch die US-PS 31 72 798 bekannten weiteren Verfahren werden zum Herstellen einer Verbindung die beiden Gewebelagen und ein Thermoplaststreifen in dieser Reihenfolge übereinanderliegend zunächst zusammengenäht, die obere Gewebelage wird um den Thermoplaststreifen um 180° umgefaltet, so daß der Streifen in der gebildeten Umschlagfalte innen liegt. Sodann werden die übereinanderliegenden Lagen im Hochfrequenz-Schweißverfahren miteinander verschweißt. Dabei muß das Werkstück abschnittsweise positioniert und geschweißt werden. Die Arbeitsweise erfolgt also taktweise und ist daher recht zeitraubend. Das Schweißen bestimmter Rundungen macht darüber hinaus entweder den Wechsel von Schweißwerkzeugen erforderlich oder es können nur relativ kurze Werkzeuge eingesetzt werden. Da der Faden bei hoher Beanspruchung in den Nadeldurchstichlöchem arbeitet, können trotz Hochfrequenzschweißung Undichtigkeiten auftreten.
Schließlich ist durch die DE-AS 20 33 830 ein Verfahren bekannt, nach dem zwischen die zu verbindenden überlappt liegenden Ränder der beschichteten Materiallagen ein über die beiden Randkanten hinausragender Streifen aus thermoplastischem Kunststoff eingelegt und durch eine oder mehrere Nähte die Materiallagen und der Streifen zu einem Verbund zusammengenäht werden. Der eine Rand oder beide herausragenden Ränder des Streifens werden dann umgebogen, über die vernähten, doppellen Lagen des Verbundes gelegt und dort mit dem oder den beschichteten MateriallagenAccording to a further method known from US Pat. No. 3,172,798, the two fabric layers and a thermoplastic strip are first sewn together in this order one above the other, the upper fabric layer is folded around the thermoplastic strip by 180 ° so that the strip is in the formed Inside fold. The superimposed layers are then welded together using a high-frequency welding process. The workpiece must be positioned and welded in sections. The way of working is therefore cyclical and is therefore quite time-consuming. The welding of certain roundings also makes it necessary to either change welding tools or only relatively short tools can be used. Since the thread works in the needle puncture holes under high stress, leaks can occur despite high-frequency welding.
Finally, from DE-AS 20 33 830 a method is known, according to which a strip of thermoplastic material protruding beyond the two edge edges is inserted between the overlapping edges of the coated material layers to be connected and the material layers and the strip become one through one or more seams Composite are sewn together. One edge or both protruding edges of the strip are then bent over, placed over the sewn, double layers of the composite and there with the coated material layer or layers

so durch Hochfrequenzschweißung verschweißt.so welded by high frequency welding.

Die nach diesem Verfahren hergestellte Verbindung ist zwar von guter Qualität und läßt Dauerfestigkeit erwarten, jedoch ist diese Verbindung insbesondere für Bekleidung nicht geeignet, weil sie eine sehr starke Verdickung in den Materialbahnen bildet, die nicht biegeelastisch und geschmeidig genug ist.The connection produced by this process is of good quality and has fatigue strength expect, however, this connection is not particularly suitable for clothing because it has a very strong thickening forms in the material webs that are not flexible enough and flexible enough.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Verbinden von einseitig kunststoffbeschichteten Materiallagen zu entwickeln, nach dem besonders haltbare, flache, wasserdichte Verbindungen mit relativ hoher Vorschubgeschwindigkeit kontinuierlich hergestellt werden können, sowie eine Vorrichtung zur Durchführung des Verfahrens zu schaffen, mit der das zu verbindende Material exakt geführt und ausgerichtet wird.The invention is based on the object of a method for connecting one-sided plastic-coated To develop material layers, after which particularly durable, flat, waterproof connections with relatively high feed rate can be produced continuously, as well as a device for Implementation of the process to create with which the material to be connected is precisely guided and aligned will.

Beim Vorgehen nach dem erfindungsgemäßen Verfahren kann eine Perforation der Matcriallagen durch Nähen entfallen. Die mit dem Nähen verbundenenWhen proceeding according to the method according to the invention, a perforation of the matric layers can occur through No need for sewing. Those associated with sewing

Nachteile werden vermieden, weil durch die innige Verbindung aller sich gegenüberliegenden Schichten die Verbindung eine gleich gute Festigkeit wie eine durch Nähen und Schweißen hergestellte Verbindung hat. Sie ist auch reinigungsbeständig, womit eine wichtige Forderung für Bekleidung aus beschichtetem Material erfüllt wird. Ein weiterer Vorteil besteht darin, daß die Verbindung keiner Schälwirkung unterworfen ist und daher eine wesentlich höhere Zugfestigkeit als die bisher üblichen sogenannten Schälnähte hat Das sind Nähte, bei denen die beiden Materiallagen mit der beschichteten Seite aufeinanderliegend verschweißt wurden.Disadvantages are avoided because the intimate connection of all opposing layers Connection has the same strength as a connection made by sewing and welding. she is also resistant to cleaning, which fulfills an important requirement for clothing made of coated material will.
