Abstract:
Methods and apparatuses for forming a nonwoven web are described herein. The apparatus includes a mixing partition defining one or more openings therein that permit fluid communication between two fluid flow streams, at least one of which includes a fiber. The apparatus also includes an enclosed region surrounding at least a portion of the mixing partition. The enclosed region is adapted to provide an applied pressure to a fluid flow stream to urge the stream through one or more of the openings in the mixing partition. The apparatus also includes a receiving region designed to receive at least a combined flow stream and form a nonwoven web by collecting fiber from the combined flow stream.
