This method allows a coating product to be applied to a component () being moved by a conveyor (), along which conveyor at least one spray () is arranged. It comprises automated steps involving determining, within a fixed frame of reference (X, Y, Z), the coordinates of the points (A, B, C, A, B, C) of one or more lines (L, L) of the exterior profile of the component which are distributed along the length of the component, in assigning to each spray the points of each exterior profile line that lie within its field of spraying, in identifying, from among the points assigned to each spray, the point (A, A; B, B) closest to the spray for each exterior profile line, in determining, for each spray, a line (L, L) to follow that passes through all the points (A, A, B, B) closest to the spray as identified in step c), and in establishing a reference path for each spray according to the points on the line (L, L) to follow so that the application distance of each spray is adjusted automatically and independently according to the exterior profile of the component.

This electrostatic sprayer of coating products with external load, comprises a bowl rotatable about an axis, a turbine for rotating the bowl around this axis, and a plurality of first electrodes distributed around the axis and each capable of emitting, when the sprayer is operating and is at least partly in the direction on an object to be coated, a first ion flux from a first point. The first points are arranged in a first circle centered on and perpendicular to the axis. The sprayer comprises second electrodes each capable of emitting, when the sprayer is operating and mainly or exclusively in the direction of an edge of the bowl, a second ion flux, of the same sign as the first ion flux, from second points arranged in a second circle centered on and perpendicular to the axis, and having a different radius than the first circle.

Rotating projector for a coating product including a spraying device having a circular spraying edge, driving means for driving the spraying device around a rotational axis, a body including primary openings arranged on a primary contour for ejecting primary air jets in a primary direction. The air jets having an axial component and an orthoradial component which are nonzero. The primary direction has a nonzero radial component, which is centrifugal relative to the rotation axis. Each primary jet extends along the rotational axis at a distance from the rotational axis than the radius of the spraying edge. The body includes secondary openings arranged on a secondary contour for ejecting the secondary air jets in a secondary direction having axial and centripetal radial components.
