Abstract

A deposition cavity apparatus for forming an airlaid article is in communication with a duct carrying a stream of air-entrained fibrous material to an airlaying location. The cavity apparatus has a frame portion in sealing engagement with the duct. A foraminous portion is also provided and is of a size sufficient to retain the air-entrained fibrous materials, whereby an airlaid article is formed in the region of the foraminous surface.
