Abstract
Embodiments relate to a fine particle applicator including a loading vessel, a metering roller positioned adjacent the loading vessel, a first stippling roller in contact with the metering roller, a high speed roller, positioned adjacent the metering roller such that bristles of the metering roller and bristles of the high speed roller overlap sufficient to form an interference zone, a second stippling roller, in contact with the high speed roller, a stippling shoe positioned adjacent at least the metering roller and high speed roller and a housing. At least a portion of a surface of the stippling shoe closest to at least the metering roller and high speed roller includes substantially the same curvature as the roller nearest the surface.
