Abstract
A method and system are provided for dispersing a plurality of closely associated filaments so that the dispersed filaments are capable of being deposited, in a random, convoluted pattern, on a moving web-forming surface to form a high machine-direction strength nonwoven product. The filaments are preferably dispersed by impinging same against a fluid-dynamically-assisted, contoured deflection means, preferably comprising a curved, downwardly inclined deflection element which is continuously traversed, generally codirectional with the filament flow, by a stream of air.
