System and method for dispersing filaments

摘要

A system and method are provided for dispersing a plurality of filaments, moving at high velocity, without substantial fiber aggregation, for subsequent uniform deposition on a web-forming surface, by the use of opposed Coanda nozzles. The Coanda nozzles are operated under nonsteady-state conditions whereby a substantially nonsymmetrical filament pattern is created between the opposed Coanda surfaces.
