Abstract

The filler is suitable for the treatment of fluids or gases, in particular for the biological treatment (aeration) of waste waters. In a certain filler (11) several bands (19) are interconnected by means of a fixing cloth (23). The connection between the bands and the fixing device in the form of afixing cloth (23) is made by pulse welding method as a result of which bands (19) and/or cloth (23) may be damaged. The new filler offers the opportunity for a simpler make of the band connection without damaging the filler. The band connection is made by at least one section (21) applied in soften state onto bends (19). 28 claims, 12 figures
