Patent ID: 8435600

Claim:
A method of dispensing a plurality of adhesive filaments onto a substrate in a random pattern, comprising: moving the substrate along a machine direction; discharging the plurality of adhesive filaments from a plurality of liquid outlets, each liquid outlet being located in a liquid discharge plane; directing at least one of a plurality of first pressurized process air streams toward a respective one of the plurality of adhesive filaments, each of the first pressurized process air streams flowing along a first plane oriented along a first angle relative to the liquid discharge plane; directing at least one of a plurality of second pressurized process air streams toward a respective one of the plurality of adhesive filaments, each of the second pressurized process air streams flowing along a second plane oriented along a second angle relative to the liquid discharge plane, wherein only the plurality of first pressurized process air streams is directed along one side of the liquid discharge plane and only the plurality of second pressurized process air streams is directed along an opposite side of the liquid discharge plane, and the second angle being different than the first angle so that the first and second pressurized process air streams are directed asymmetrically toward the plurality of adhesive filaments; and depositing the plurality of adhesive filaments on the substrate in a random pattern.
