<p>A liquid dispensing module (10) and nozzle or die tip (28) for discharging at least one liquid filament (74). The nozzle (28) includes a strand guide or notch (42) for guiding a substrate past the nozzle (28) and a frustoconical protrusion (56) disposed on a surface of the nozzle adjacent the notch (42). A liquid discharge passage (48) extends along an axis (48a) through the frustoconical protrusion (56) and forms an acute angle with a machine direction corresponding to movement of the strand (44) past the nozzle (28). Four air discharge passages (60, 62, 64, 66) are positioned at the base of the frustoconical protrusion (56). Each of the air discharge passages (60, 62, 64, 66) is angled in a compound manner generally toward the liquid discharge passage (48) and offset from the axis (48a) of the liquid discharge passage (48) to create the controlled pattern of liquid material (74) on the strand (44).</p> |
