Method and apparatus for coating moving substrates

The invention relates to a process for coating substrates with a powder layer by powder deposited electrostatically on the surface of a transfer device, the transfer device and the substrate relative to each other in a transfer region in the same or opposite direction or is guided transversely to each other, wherein in the transfer region with of the powder layer coated surface of the transfer device and the forming a gap are located opposite one another to be coated surface of the substrate, and the powder in the transfer region is transferred from the transfer device onto the substrate. DOLLAR A in the transfer region is generated by at least one with respect to the gap behind the transfer device and / or arranged behind the substrate electrode, a substrate, the powder particles to the moving electric field.
