Abstract
A spray die for applying a substantially uniform, continuous coating of fluid onto a substrate is disclosed. The spray die includes a plurality of fluid nozzles which are disposed linearly to eject a two-dimensional spray fan of fluid onto the substrate. The diameter of each fluid nozzle is selected in combination with the flow rate and viscosity of the ejected fluid. A pair of air nozzles is disposed on opposite sides of each fluid nozzle to provide a pair of opposing air streams which impinge on the fluid nozzle behind the orifice of the nozzle.
