Description

Die Erfindung betrifft eine Vorrichtung zuu Verbinden und Bilden eines Stoffes aus zwei oder mehr Schichten aus textflem Faserstoff, von denen mindestens eine einen thermoplastischen Stoff enthält, mit mehreren Schwingungsübertragungsgliedern, die mit der obersten Schicht in Berührung stehen und untereinander in Längsrichtung der Schichten versetzt und in mindestens zwei parallelen Reihen angeordnet sind und sich entlang von Achsen erstrecken, welche senkrecht zu der Achse der Schichten verlaufen, und mit einer auf der anderen Seite der Schichten liegenden,
als Drehkörper ausgebildeten Gegenhalteeinrichtung, deren Breite mindestens einem Großteil der Breite des textlien Faserstoffes entspricht, und deren Gegenhalteflächen mit den entsprechenden Arbeitsflächen der Schwingungsübertragungsglieder bei zusammenwirkender Deckungsgleichheit parallel verlaufen.
Eine solche Vorrichtung ist in dem älteren Patent 2261169 angegeben. Dabei entsteht das Problem, daß während des Verschweißen in den Bereichen zwischen den Schwingungsübertragungsgliedern der ersten Reihe Falten in den zu verschweißenden Schichten auftreten können, die dann von den Schwingungsübertragungsgliedern der zweiten Reihe in das Material eingeschweißt werden.
Dieser unerwünschte Nebeneffekt wird dadurch sieher ausgeschaltet, daß in Weiterbildung der älteren Erfindung Andruckstempel im Abstand von und zwischen den Schwingungsübertragungsgliedern der ersten Reihe angeordnet sind, die auf die Schichten des textlien Faserstoffes drückbar sind. Dadurch ist es erstmals möglich, beliebige Muster faltenfrei über die volle, nur von der Maschinengrößc begrenzte Breite der Schichten in einem einzigen Arbeitsgang zusammenhängend zu verschweißen.
Weiterbildungen dieser Erfindung sind in den Unteransprüchen angegeben.
Anhand der Zeichnung wird der Gegenstand der Erfindung näher erläutert. Es zeigt
Fig. 1 eine unvollständige Draufsicht auf eine SchwingungsschweiBvorrichtung entsprechend der
so Erfindung,
Fig. 2 einen Schnitt entlang der Linie 2-2 in Fig. 1 in Richtung der Pfeile, und
Fig. 3 einen Schnitt entlang der Linie 3-3 in Fig. 1 in Richtung der Pfeile.
Eine allgemein mit 10 bezeichnete Ultraschall-Schweißvorrichtung hat ein Traggestell 12. In dem Gestell 12 sind Schwingungsübertragungsglicder 16 und Gegenhalteflächen angeordnet, die die verschiedensten Formen haben können, aber im vorliegenden Fall aus einer Walze 18 mit einer Reihe von in einem Muster angebrächten Vorsprüngen 20 bestehen. Die Walze 18 ist in dem Gestell 12 gelagert und wird von nicht dargestellten Antriebsmitteln bekannter Bauart in Drehung versetzt. Die Vorsprünge 20 haben Au-
