Title: Omega spray pattern and method therefor

Abstract: A method for producing visco-elastic fluidic material flows by drawing a visco-elastic fluidic material with corresponding separate second fluid flows associated therewith to form a visco-elastic fiber vacillating in a repeating, generally omega-shaped pattern having a bowed portion with first and second side portions that first converge toward each other and then diverge outwardly in generally opposing directions. In one operation, the visco-elastic fiber vacillating in the repeating, generally omega-shaped pattern is an adhesive material deposited onto woven and non-woven fabric substrates and stretched elongated elastic strands in the manufacture of a variety of bodily fluid absorbing hygienic articles.
