Abstract

Verfahren zur Herstellung von luftgefüllten Verpackungspolstern aus einer Bahn von vorkonfiguriertem Folienmaterial, welches einen sich in Längsrichtung erstreckenden Aufblaskanal und eine Vielzahl von aufblasbaren Kammern aufweist, die mit dem Aufblaskanal durch sich seitlich erstreckende Einlassöffnungen in Verbindung stehen, wobei es die Schritte umfasst: das kontinuierliche und ununterbrochene Vorrücken einer Bahn des vorkonfigurierten Folienmaterials entlang eines Pfads, das Aufblasen der Kammern im Material durch den Aufblaskanal, während das Material entlang des Pfads vorrückt, und das Herumführen des Folienmaterials um den Umfang einer Abdichtwalze und in direktem Gleitkontakt mit einem erwärmten Abdichtelement, um die Einlassöffnungen im vorrückenden Folienmaterial abzudichten.
