ABSTRACT:
A multi-orifice T-bar nozzle includes a nozzle body having a mounting plate adapted to connect to the body of a hot melt thermoplastic adhesive dispenser, and an internal adhesive flow path formed by an inlet at the top wall of the nozzle body adapted to receive adhesive from the adhesive dispenser, a number of outlets at the bottom wall thereof which extrude adhesive beads and a distribution passageway interconnecting the inlet and outlets. The nozzle body progressively tapers from the top, center portion thereof to its extremities, i.e., to the end portions and bottom of the nozzle body, so that the temperature differential between the adhesive entering the inlet of the nozzle body, and the adhesive discharged from the outlets, is minimized.
