For example, as shown schematically in the Figure 5, where D represents the surface density of the coating agent, the surface of total impact of two juxtaposed projection means can undergo not only radial variations in density, as is the case with only one means of projection, but also very significant variations in density in the area of contact between the projection cones and the impact surfaces, even if the coating may be close to the nominal value N in areas S where impact surfaces do not not overlap.
