A bead applicator for embedding particulates in wet paint, includes a blower directing air into an attached series of connected pipes; a particulate hopper, and a tubular particulate supply line connecting an outlet opening from the hopper to a venturi inlet opening at a low pressure point of a venturi tube. The series of connected pipes includes, in order, the venturi tube, a rigid tubular wand, and a dispensing nozzle. The wand, an inlet of the nozzle, and an outlet of the nozzle all have approximately the same, or greater, inside cross-sectional area relative to that of an outlet of the venturi tube; and the nozzle fans out to a long and narrow shaped outlet. Preferably a flexible hose is included in the series of connected pipes; the hose having approximately the same, or greater, inside cross-sectional area relative to that of the venturi tube outlet, and the nozzle outlet is bent over. |
