Procedure electrostatic application of a powder on a support with particularly irregular surface state.

摘要

Method for coating electrostatically a support (1) comprising a surface (2) to be coated, comprising the following steps: - a body projection (6) emits a jet (8) of dust particles electrically charged toward the support, - a generator (16) establishes an electric potential level of the surface to be covered so that dust particles are attracted to this surface, - a deflector (17) is disposed against the surface so that at least part of the dust particles to deflect and form a cloud (18) between this deflector and the surface, being attracted this cloud uniformly to the surface under the effect of the electrostatic attraction generated by said surface, characterized in that the deflector is independent of the body projection.
