Abstract
A spray nozzle is disclosed that produces a flat spray pattern for liquid coating material, the spray pattern having a generally uniform flow distribution of quantity of coating material across the spray pattern. The spray nozzle may include a rectangular cut spray orifice to produce such a spray pattern. The spray pattern may further have distinct edges so that the pattern exhibits substantially reduced tailings of coating material outside these edges. In one embodiment, the spray pattern produces a 'rectangular' drip pattern. In another embodiment, the spray pattern may include a middle region having reduced flow of coating material as compared to side regions of the spray pattern.
