Abstract:
A nozzle for dispensing a random pattern of liquid adhesive filaments. The nozzle may include first and second air shim plates, an adhesive shim plate and first and second separating shim plates. The first and second air shim plates each have respective pairs of air slots. Each air slot has a process air inlet and a process air outlet and the air slots of each pair converge toward one another such that the process air inlets are farther apart than the process air outlets in each pair. The adhesive shim plate includes a plurality of liquid slots each with a liquid outlet. Four process air outlets are associated with each of the liquid outlets. The process air slots are adapted to receive pressurized process air and the liquid slots are adapted to receive pressurized liquid adhesive. The pressurized process air discharges from each group of the four process air outlets and forms a zone of turbulence for moving the filament of liquid adhesive discharging from the associated liquid outlet in a random pattern.
