DYNlMTD NOBEL AKTIENGESELLSCHAFT Troisdorf, Bez. Köln
Verfahren zum HF-Veischweißen von PYC-Schaum mit siebartig durchbrochenen
Materialien
Die Erfindung bezieht sich auf ein Verfahren zum HF-Verschweißen von PVC-Schaum mit siebartig durchbrochenen Materialien
wie Trikot, Nessel, perforierte Folie od.dgl..
Beim HF-Schweißen von PVG-Schaum mit siebartig durchbrochenen
Materialien ist es bekannt, wenigstens die auf die Seite des siebartig durchbrochenen Materials befindliche Elektrode mit einer
Isolierschicht zu versehen, die im wesentlichen die Funktion der Verhinderung von Durchschlägen und/oder Randüberschlägen,
der thermischen Isolation, der Schweißgut-, Zusatz- oder Sekundärerwärmung sowie der Verhinderung des Anhaftens des
Schvreißgutes an der Elektrode hat. Seinen Aufgaben entsprechend werden an den Isolierstoff hohe Anforderungen in bezug auf die
Durchschlagfestigkeit, Temperaturbeständigkeit, Dielektrizität und mechanische Beschaffenheit gestellt. In der Praxis finden
zur Zeit unter anderem Phenolharz-Cellulose-Hartpapier, Silikon-Glasgewebe,
Gummigewebe-Verbindungen, Folien aus diversen Gummiarten, Polytetrafluoräthylen-Glasgewebe, Polytherephthalsäureester
und Celluloseacetate, Öl- und Lackleinen, Silikonfolie, Polyäthylen-und Polypropylenfolie, öl- und Pergamin-Papiere, Epoxydharz
und andere Duroplaste, Glas-, Abest- und Glimmverbindungen Bowie streichfähige Isolierfilme Verwendung. Alle diese Isolierstoffe
haben eine glatte bzw. verhältnismäßig glatte Oberfläche,
Wie eich in der Praxis gezeigt hat, ergeben HF-Verschweißungen
von PVC-Schaura mit einem Gewebe aus Trikot, Nessel od. dgl.
009850/178 9
" Z " BAD ORIGINAL
bei Verwendung von Isolierschichten aus den vorstehend genannten Isolierstoffen mit glatter bzw. verhältnismäßig glatter
Oberfläche keine gute Sehweißnahtfestigkeit.
Um die Schweißnahtfestigkeit zu verbessern, wurde daher schon vielfach als Gewebe ein beidseitig mit Weich-PVC beschichtetes
■Gittergewebe verwendet, wobei sich dann beim Schweißen die PVO-Beschichtung mit dem PVC-Schaum verbindet. Abgesehen von
den hohen Kosten hat diese Methode vor allem den Nachteil einer großen Steifheit des Gewebes, was in den meisten Fällen
jedoch unerwünscht ist.
Die Erfindung beschreitet einen anderen Weg und sieht vor, die dem Schweißgut augekehrte Seite der Isolierschicht mit zahlreichen
verhältnismäßig kleinen Erhebungen und/oder Vertiefungen zu versehen, so daß der durch den HP-Strom erwärmte und
plastisch gemachte PVG-Schaum durch das Gewebe hindurch zwischen die Erhebungen bzw. in die Vertiefungen eindringen und
sich nach Abkühlen des PVC-Schaums mit dem Gewebe mechanisch verankern kann. Aufgrund dieser Maßnahme ist es nunmehr ohne
weiteres möglich, die obenerwähnten glatten Isolierstoffe mit gutem Erfolg zu verwenden und eine feste und dauerhafte Verbindung
selbst dann zu erzielen, wenn das Gewebe aus einem Material hergestellt ist, das sich mit dem PVG-Schaum nicht
hochfrequent verschweißen läßt. Versuche haben gezeigt, daß sich etwa dreimal so hohe Schweißnahtfestigkeiten erzielen
lassen wie bisher.
Das vor allem für die Auto-, Polstermöbel- und Matratzenindustrie
geeignete erfindungsgeraäße Verfahren wird anhand der in der Zeichnung gezeigten Ausfiihrungsbeispiele im folgenden noch
erläutert. Es zeigen
009850/17 89
Pig. 1 eine Schwelßanordnung mit einer Isolierschicht
mit gewellter Oberfläche,
Pig. 2 eine als grobes Gittergewebe ausgebildete Isolierschicht und
Pig. 3 eine Isolierschicht aus Hartpapier.
Auf der an ihrer dem Schweißgut 2, 3 und 4 zugekehrten Seite ist die Isolierschicht 1 wellenförmig ausgebildet, so daß das
Untergewebe 2 nur stellenweise auf der Isolierschicht aufliegt, im übrigen aber zwischen Untergewebe 2 und Isolierschicht 1 die
Hohlräume 6 gebildet sind. Der mit der Deckschicht 4 .aus Gewebe, Leder, Kunstleder, Polie od.dgl. abgedeckte PVC-Schaum 3
hat sich im Bereich der Elektrode 5 erwärmt und ist in plastischem Zustand- durch das Untergewebe 2 hindurch in die Vertiefungen
bzw. Hohlräume 6 eingedrungen, wodurch nach dem Abkühlen des PVC-Schaums eine gute mechanische Verankerung zwischen
ihm und dem Untergewebe 2 hergestellt ist. Gleichzeitig hat sich der PVC-Schaum in dem genannten Bereich auch mit der .
Deckschicht 4 verbunden.
Die in Pigur 2 gezeigte gitterartig ausgebildete Isolierschicht
bev/irkt ebenso wie die in Pigur 3 gezeigte, auf ihrer dem Schweißgut zugekehrten Seite genutete Hartpapier-Isolierschicht,
daß das Untergewebe nur stellenweise aufliegt, und daß der im Bereich der Elektrode erwärmte und in den plastischen Zustand
übergegangene PVC-Schaum durch das Untergewebe hindurch in die dahinter ausgebildeten Hohlräume eindringen und sich
00 9 8 50/1789
nach Erkalten des PVC-Schaums mit dem üntergewebe mechanisch
verankern kann.
