Abstract:
A module for dispensing multiple liquid filaments onto a moving substrate with a swirled pattern, comprising:a module body having a liquid supply passage and an air supply passage for respectively receiving liquid and air; a nozzle body having a first side and a second side, said first side coupled with said module body and including a liquid supply port and an air supply port coupled with respective liquid and air supply passages of said module body; a wedge-shaped member on said second side of said nozzle body and including a base, an apex and a pair of side surfaces converging toward said apex; a plurality of liquid discharge passages extending along respective axes through said apex of said wedge-shaped member, said liquid discharge passages communicating with said liquid supply port, and said wedge-shaped member extending in a radially asymmetrical manner around said liquid discharge passages; and a plurality of sets of air discharge passages in said nozzle body and positioned adjacent said base of said wedge-shaped member, each set having at least two of said air discharge passages positioned adjacent each of said side surfaces, and said air discharge passages of each respective set angled in a direction generally toward an associated one of said liquid discharge passages and said air discharge passages of each set offset from the axis of said associated one of said liquid discharge passages to produce a swirled liquid filament pattern on the substrate upon impact of the liquid filament discharged from said liquid discharge passage of said respective set.
