Abstract
A one-piece nozzle adapted for use within an adhesive dispenser includes a nozzle body formed with a throughbore having a discharge outlet within a nozzle tip portion which emits a bead of adhesive. A nozzle cap mounts the nozzle body to the adhesive dispenser such that an adhesive passageway within the dispenser communicates with the throughbore in the nozzle body and a plunger valve associated with the adhesive dispenser extends into the nozzle body in position to engage a seat formed at the nozzle tip. A number of air jet bores are drilled in the nozzle body, each communicating with an air passage formed between an outer surface of the nozzle body and an inner surface of the nozzle cap, which discharge jets of air into contact with the adhesive bead producing an elongated adhesive fiber deposited in a spiral pattern onto a substrate.
