Beschreibung
Zusammenfassung:	A nonwoven web contains an even distribution of its composite materials by the separate application of particulate material such as superabsorbent particles into a forming head outside the air stream for deposition of thermoplastic fibers in the forming head. The thermoplastic fibers are distributed by air entertainment through tubular forming screens having rotary distribution members therein. The particulate absorbents are generally placed in the forming box by distribution units which may have metering devices and outlet chutes extending into the forming head.
