Abstract

Apparatus and method for spraying or scattering solid particulate powders onto a substrate includes powder spraying or scattering means, conveyor for supporting and conveying the substrate and rotatable disc member disposed between the spraying or scattering means and the conveyor which is spaced therefrom. The disc member is formed with at least an opening through which powders sprayed or scattered from the spraying or scattering means pass to reach the substrate on the conveyor. In operation, the disc member is rotated and the substrate is moved by the conveyor in the same direction.
