Abstract
A method of dispensing multiple adhesive filaments onto a substrate in a random pattern using asymmetrical pressurized process air. The method generally comprises moving the substrate along a machine direction and discharging multiple adhesive filaments from a plurality of liquid outlets. Pressurized process air is directed toward each one of the multiple adhesive filaments respectively along a first angle relative to a plane including an associated liquid outlet. Pressurized process air is also directed toward each one of the multiple adhesive filaments respectively along a second angle relative to the plane including the associated liquid outlet and on an opposite side of the associated liquid outlet than the pressurized process air directed along the first angle. The second angle is different than the first angle so that the pressurized process air is directed asymmetrically toward the multiple adhesive filaments.
