Description

Verfahren zum Verbinden thermoplastischer Folien mit artfremden Werkstoffen nicht thermoplastischer Eigenschaft Die Erfindung befaßt sich mit einem Verfahren, das dem Zweck dient, folienförmige thermoplastische Körper mit artfremden Werkstoffen nichtthermoplastischer Eigenschaft, wie Textilien, Holz.Process for joining thermoplastic foils with alien materials not thermoplastic property The invention relates to a method which serves the purpose of film-shaped thermoplastic bodies with alien materials non-thermoplastic properties, such as textiles, wood.

Metall, Leder od. dgl., zu verbinden.Metal, leather or the like. To connect.

Es wurde bereits ein Verfahren angegeben, mit dessen Hilfe es gelingt, eine mechanische Verbindung zwischen einem thermoplastischen Stoff und einem nichtthermoplastischen herzustellen. Dieses setzt jedoch voraus, daß der artfremde Stoff eine rauhe Oberfläche hat oder porös ist, so daß der Thermoplast unter Einwirkung von Wärme und Druck in das Gefüge des anderen Stoffes einzudringen vermag. Eine derart vorgenommene Verbindung ist mechanisch nicht sehr haltbar. Das Verfahren eignet sich deswegen zwar sehr gut für flächenhafte Verbindungen zum Zweck des Beziehens oder der Stützung von Folien, es ist dabei aber weniger an Stoßverbindungen gedacht, welche einem Zug zwischen den beiden Materialien standhalten sollen. A method has already been specified with the help of which it is possible to a mechanical connection between a thermoplastic material and a non-thermoplastic material to manufacture. However, this assumes that the foreign substance has a rough surface has or is porous, so that the thermoplastic under the action of heat and pressure able to penetrate into the structure of the other substance. One made like this Connection is not very durable mechanically. The procedure is therefore suitable very good for two-dimensional connections for the purpose of relationship or support of foils, but the focus is less on butt joints, which one The aim is to withstand the tension between the two materials.

1 )as erfindungsgemäße Verfahren dagegen ist sehr gut geeignet, derartig beanspruchte mechanische Verbindungen zwischen einem thermoplastischen Stoff einerseits und einem nichtthermoplastischen Stoff andererseits herzustellen, wobei man sich nicht. die in dem bereits erwähnten Verfahren, @uf solche nichtthermoplastischen Stoffe zu beschränken <raucht, die porös sind oder eine rauhe Oberfläche aufweisen. 1) The method according to the invention, on the other hand, is very well suited to such stressed mechanical connections between a thermoplastic material on the one hand and a nonthermoplastic fabric on the other hand, being not. those in the process already mentioned, @uf such non-thermoplastic Restricting substances <smokes that are porous or have a rough surface.

I )as erfindungsgemäße Verfahren zur Herstellung solcher Verbindungen ist dadurch gekennzeichnet, daß an den Stellen, an denen die Verbindung der Werkstoffe miteinander unter Druck stattfindet, die thermoplastische Folie möglichst gleichzeitig auf dielektrischem Wege mittels eines hochfrequenten elektrischen Wechselfelds weitgehend erwärmt wird, so daß sie teilweise in die Uneben- heiten des an den genannten Stellen mechanisch aufgerauhten oder perforierten artfremden Werkstoffs eindringt. Eine Aufrauhung der Oberfläche ist hinreichend, wenn man beispielsweise zwischen glatten artfremden Stoffen und thermoplastischen Folien eine Verbindung herstellen will, deren mechanische Beanspruchung innerhalb kleiner Grenzen bleibt. I) as the process according to the invention for the preparation of such compounds is characterized in that at the points where the connection of the materials takes place with each other under pressure, the thermoplastic film as possible simultaneously largely by dielectric means by means of a high-frequency alternating electric field is heated so that it partially penetrates the uneven units of the mechanically roughened or perforated foreign material in the named places penetrates. A roughening of the surface is sufficient if, for example a connection between smooth alien materials and thermoplastic foils wants to produce whose mechanical stress remains within small limits.

Sehr weste Verbindungen dagegen erhält man, wenn der artfremde Stoff, etwa eine Metallfolie, an der mit dem thermoplastischen Material zu verhindenken Stelle perforiert ist bzw. Aussparungen I aufweist, wie es etwa in Fig. I dargestellt ist. Der filienf(irmige thermoplastische Stoff 2 wird dabei entsl)recllen(l Fig. 2 beiderseitig auf das artfremde Nfaterial 3 aufgehracht und sodann derart mittels dielektrischer Erwärmung verschweißt, daß ersterer innerhalb der Aussparungen i des zweiten zusammenfließt. Very strong connections, on the other hand, are obtained when the foreign substance, about a metal foil to prevent with the thermoplastic material Point is perforated or has recesses I, as shown for example in FIG is. The filament-like thermoplastic material 2 is then removed (l Fig. 2 on both sides on the foreign material 3 and then by means of dielectric heating welded that the former within the recesses i of the second flows together.

Hat der artfremde Werkstoff eine relativ große l)icke oder sind die thermoplastischen Folien Sehr diinll so daß sie nur einen geringen Materialabfluß iii die Aussparungen I zulassen, so erscheint es als zweckmäßig, in die Aussparungen des nichtthermoplastischen Materials zusätzlich thermoplastisches Material einzubringen. Man kann dabei etwa so vorgehen, wie es in Fig. 3 dargestellt ist, in welscher durch die Aussparungen I des artfremden Stoffs 2 ein aus thermoplastischem Material bestehender(s) Faden oder Band 4 hindurchgezogen und sodann die Schweißung vorgenommen wird. Does the foreign material have a relatively large thickness or are they thermoplastic films very diinll so that they only have a low material drain iii allow the recesses I, it appears to be useful in the recesses of the non-thermoplastic material to introduce additional thermoplastic material. You can proceed as shown in Fig. 3, in welscher by the recesses I of the foreign substance 2 made of thermoplastic material (s) Thread or tape 4 pulled through and then the weld is made.

Entsprechend Fig. 4 kann der Faden 4 aus thermoplastischem Stoff natürlich auch doppellagig durch die Aussparungen 1 des artfremden Materials 2 durchgezogen werden.According to FIG. 4, the thread 4 can of course be made of thermoplastic material also pulled through the recesses 1 of the foreign material 2 in two layers will.

Weiterhin besteht in ähnlicher Weise entsprechend Fig. 5 die Möglichkeit, den thermoplastischen Stoff 2 mit dem artfremden Stoff 3 vor der Verschweißung mittels eines aus thermoplastischem Material bestehenden Fadens oder Bands zusammenzunähen. Furthermore, in a similar manner according to FIG. 5, there is the possibility of the thermoplastic material 2 with the foreign material 3 prior to welding by means of sewing together a thread or tape made of thermoplastic material.

Die in den artfremden Stoffen vorzunehmenden Aussparungen weisen aus Festigkeitsgründen vorteilhafterweise einen trapezförmigen Querschnitt auf. The recesses to be made in the foreign fabrics show for reasons of strength advantageously a trapezoidal cross-section.

Statt der vorher beschriebenen Aussparungen kann der artfremde Körper auch mit einer entlang der Verbindungsstelle verlaufenden Nut 5 (Fig. 6) vorzugsweise trapezförmigen Querschnitts versehen werden, in welche der thermoplastische Stoff 2 I>eim Vorgang des Erwärmens hineingepreßt wird. Instead of the previously described recesses, the alien body also preferably with a groove 5 (FIG. 6) running along the connection point trapezoidal cross-section in which the thermoplastic material 2 I> is pressed in during the heating process.

Entsprechend dem Vorangegangenen ist es auch hierbei zweckmäßig, vor der Erwärmung einen Streifen thermoplastischen Materials in die Nut einzulegen.In accordance with the foregoing, it is also useful here to proceed insert a strip of thermoplastic material into the groove after heating.

Hei der Verbindung einer thermoplastischen Folie mit einem porösen Stoff, wie Textilstoff, Leder, Filz od. dgl., wird letzterer gemäß der weitergehenden Erfindung mit einer Polyvinylchloridlösung getränkt oder aber, sofern es sich um einen Textilstoff handelt, zweckmäßig bereits während des Webevorgangs des Stoffs mit mindestens einem eingewebten thermoplastischen Faden versehen. He is the connection of a thermoplastic film with a porous one Fabric, such as textile fabric, leather, felt or the like. The latter according to the further Invention soaked with a polyvinyl chloride solution or if it is is a textile fabric, expediently already during the weaving process of the fabric provided with at least one woven-in thermoplastic thread.
