Abstract:
1. A nozzle for dispensing a random pattern of liquid adhesive filaments, comprising: first and second process air shim plates, said first and second process air shim plates each having respective pairs of air slots, each air slot having a process air inlet and a process air outlet and said air slots of each pair converging toward one another such that said process air inlets are farther apart than said process air outlets in each pair; an adhesive shim plate having a plurality of liquid slots each with a liquid inlet and a liquid outlet, said adhesive shim plate positioned between and lying parallel to said first and second process air shim plates such that one of said liquid slots extends generally centrally between a pair of said air slots in said first process air shim plate and a pair of said air slots in said second process air shim plate thereby associating four process air outlets with each of said liquid outlets, said process air slots adapted to receive pressurized process air and said liquid slots adapted to receive pressurized liquid adhesive, each group of said four process air outlets capable of discharging the pressurized process air for moving the filament of liquid adhesive discharging from the associated liquid outlet in a random pattern; a first separating shim plate positioned between said first process air shim plate and said adhesive shim plate; a second separating shim plate positioned between said second process air shim plate and said adhesive shim plate; and first and second end plates secured together and sandwiching said first and second process air shim plates, said adhesive shim plate and said first and second separating shim plates together, said first end plate including a process air inlet communicating with said pairs of air slots in said first and second process air shim plates and a liquid adhesive inlet communicating with said liquid slots in said adhesive shim plate.
