Ein Gewebe aus PoIytetrafluoräthylenfasern wird in der nachstehend beschrie- ! benen Weise in diese' Folie eingebettet. Die zum Einbetten ι verwendete Vorrichtung besteht aus zwei Aluminiumblechen, j die beide an der Oberseite durch mechanische Bearbeitung ' mit einer Reihe von Rillen versehen sind, um eine Druckdifferenz zwischen den beiden Seiten des Bleches zu erzeugen. Die Druckdifferenz wird durch ein durch die Seiten— ! fläche des Bleches gebohrtes Loch, das die Rillen auf der Oberseite des Bleches verbindet, angelegt. Auf dieses Blech wird ein Drahtnetz mit einer Maschenweite von 0,25 mm so gelegt, daß die Druckdifferenz an jeder Stelle auf der Oberfläche herrscht. Ein-Blatt Asbestpapier wird auf die Oberseite des Drahtnetzes gelegt, und auf dieses. j
