Abstract
A nozzle for dispensing a random pattern of liquid adhesive filaments generally includes a plurality of liquid outlets positioned in a liquid discharge plane and first and second pluralities of air passages. The first plurality of air passages is positioned in a first plane oriented at a first angle relative to the liquid discharge plane, while the second plurality of air passages is positioned in a second plane oriented at a second angle relative to the liquid discharge plane. The first angle is different than the second angle so that pressurized process air streams from the first and second pluralities of air passages are directed asymmetrically toward adhesive filaments discharged from the liquid outlets to produce the random pattern.
