摘要：
A dispensing apparatus including an airless ribbon nozzle having a nozzle tip formed with a nozzle bore tapering radially inwardly from an inlet end to a semispherical-shaped discharge end which intersects a rectangular-shaped discharge slot. The nozzle is mounted in position on a coating dispenser such that the inlet of the nozzle tip communicates with a coating passageway within the dispenser to receive coating material which is emitted from the discharge slot of the nozzle tip in a wide, splash-free, leaf-shaped pattern.
