A method of manufacturing a disposable absorbent personal hygiene product, including a stretched elastic strand and a flat substrate portion, includes mixing a pressurized gas and hot melt adhesive to form a foamed adhesive and contact dispensing the foamed adhesive onto the stretched elastic strand by contacting the stretched elastic strand with the foamed adhesive. The foamed adhesive expands in volume on the stretched elastic strand and this expansion provides improved bond characteristics and/or reduced add on weight when the stretched elastic strand is secured to the flat substrate portion, thereby improving the personal hygiene product. The foamed adhesive may also be spread around on a periphery of the stretched elastic strand by wiping the foamed adhesive with a notch in a contact nozzle or by discharging air at the foamed adhesive in contact with the stretched elastic strand.
