Abstract
Apparatus for producing a spray of particles includes a shroud for restricting the spray produced by an atomizer, leaving a restricted arc or arcs over which particles can be ejected from the apparatus. The shroud includes at least one shielding element comprising an array of bristles. Each array of bristles can be carried by a flexible elongate element so that the form and extent of the array can be adjusted. The atomizer can be a rotary atomizer.
Claims11
An apparatus for producing a spray of particles comprising means for generating a spray of particles and shrouding means arranged about the spray-producing means leaving a restricted arc or arcs over which particles can be ejected from the apparatus, characterised in that the shrouding means includes a shielding element or elements (84 to 87) comprising, or each comprising, an array of bristles and arranged about the spray-producing means so that the spray of particles produced thereby impinges directly on the array or arrays of bristles and is thereby intercepted except in the arc or arcs over which particles are to be ejected from the apparatus.
