ABSTRACT:
Paint applied to a wheel electrostatically in the dry state is removed subsequently from the hub by a method of which the first step is to block the hub from one side with a plate, offered to a first face of the wheel and of shape such that it combines with the substantially cylindrical bore of the hub to create a chamber which remains accessible from the opposite face of the wheel. A jet of air is then generated close to the hub and introduced into the chamber, investing the cylindrical surface directly or indirectly or obliquely and creating a turbulence sufficient to remove the unwanted layer of paint; at the same time, suction is generated at least in the part of the chamber flooded with air, in such a way as to aspirate and recover the particles of paint removed from the hub and held in suspension by the resulting swirl.
