ABSTRACT:
A hopper gravity feeds powder into a closeable chute. The outlet of the chute is in wiping contact with the surface of a journaled and partially enclosed roller. One or more grooves are disposed in the roller for receiving gravity discharged powder from the chute. As the exposed part of the roller is rolled across a surface, the powder is transported by the grooves from the chute to the surface and deposited thereon in a configuration commensurate with that of the depositing groove.
