A method of manufacturing a disposable absorbent personal hygiene product including a stretched elastic strand and a flat nonwoven substrate includes mixing a pressurized gas and hot melt adhesive to form a foamed adhesive. A filament of foamed adhesive is discharged toward the stretched elastic strand and deposited onto the stretched elastic strand so that the foamed adhesive expands in volume on the stretched elastic strand. The stretched elastic strand is secured to the flat nonwoven substrate with the foamed adhesive. Alternatively, the foamed adhesive secures two flat nonwoven substrate portions of the disposable absorbent personal hygiene product together.
