Abstract:
1. A nozzle for dispensing a plurality of liquid adhesive filaments in a random pattern, comprising: a plurality of liquid outlets positioned in a liquid discharge plane and configured to respectively discharge the plurality of liquid adhesive filaments along the liquid discharge plane; a first plurality of air passages positioned in a first plane oriented at a first angle relative to the liquid discharge plane, each air passage of said first plurality of air passages being associated with one of said liquid outlets and configured to direct a first pressurized process air stream along the first plane; and a second plurality of air passages positioned in a second plane oriented at a second angle relative to the liquid discharge plane, each air passage of said second plurality of air passages being associated with one of said liquid outlets and configured to direct a second pressurized process air stream along the second plane, wherein said second plurality of air passages is located on an opposite side of the liquid discharge plane from said first plurality of air passages so that only the first pressurized process air streams are directed along one side of the liquid discharge plane and only the second pressurized process air streams are directed along an opposite side of the liquid discharge plane, said first angle being different than said second angle so that the first and second pressurized process air streams are asymmetrically directed from said first and second pluralities of air passages toward each of the plurality of liquid adhesive filaments to produce the random pattern.
