Patent ID: 6863225

Claim:
A nozzle for dispensing a liquid adhesive to strand materials used in the manufacture of nonwoven products, comprising: a nozzle body having a liquid supply passage and a first liquid discharge orifice in fluid communication with said liquid supply passage, said first liquid discharge orifice extending along a first axis and configured to discharge a first bead of the adhesive, first and second pattern air discharge orifices in said nozzle body and associated with said first liquid discharge orifice, said first and second pattern air discharge orifices arranged 180° apart on opposite sides of said first liquid discharge orifice and configured to direct pressurized pattern air at the first bead of adhesive discharged through said first liquid discharge orifice thereby vacillating the first bead of adhesive back and forth in a vacillation plane containing said first and second pattern air discharge orifices, and first and second cleaning and stabilizing air discharge orifices in said nozzle body and associated with said first liquid discharge orifice, said first and second cleaning and stabilizing air discharge orifices arranged 180° apart on opposite sides of said first liquid discharge orifice and positioned 90° from said first and second pattern air discharge orifices, said first and second cleaning and stabilizing air discharge orifices configured to direct pressurized cleaning and stabilizing air in a direction parallel to said first axis to clear airborne contaminants away from said first liquid discharge orifice and to stabilize the first bead of adhesive in said vacillation plane.
