Abstract
An electrically non-insulative, typically metal, atomizer bell is housed in a shroud-like housing. A prime mover, such as an air turbine motor, typically also housed in the housing, rotates the bell to atomize coating material delivered to the bell. A second shroud movable relative to the bell has a first, retracted orientation in which the second shroud does not shield the charging portion from the approach of articles to the bell and a second, projected orientation in which the second shroud does shield the bell from the approach of articles to reduce the likelihood of disruptive electrical discharges from the bell.
