    Abstract: Ein bahnförmiges Kunststoffmaterial in Form von Folien oder Schaumstoffen wird kontinuierlich und freitragend durch eine mit einer verdünnten Fluor atmosphäre gefüllte Reaktionskammer (2) geleitet. Man fluoriert so lange, bis die Oberflächenenergie des Kunststoffmaterials (1) mindestens 45 mN/m beträqt. Ferner wird ein Austausch der verdünnten Fluor atmosphäre in der Reaktionskammer (2) mit der äußeren Atmosphäre weitgehend verhindert.

    Abstract: An extruder (22) for delivering foamed glue from a foamer selectively to a plurality of spaced apart outlet orifices (104) for extrusion onto a substrate surface and to bypass passageways (62) for diverting the foamed glue to a defoamer for subsequent return to the foamer, is formed of three elongated flat blocks (42, 44, 46) secured together releasably in face-abutting relationship. The surface of the outer, inlet (42) and bypass (44) blocks facing the center coupling block (46) are recessed to provide a plurality of passageways all of which extend substantially equal dis. tances from inlet (52. 54, 56) and bypass ports (68. 66, 64) in the inlet and bypass blocks, respectively, to a plurality of coupling ports (26) in the coupling block. An air pressure operated selector valve (80, 82) in the bypass block (44) is operable to communicate the coupling ports selectively with the bypass passageways for bypassing foamed glue to the defoamer and with the outlet orifices for extruding foamed onto a substrate surface.
