1. A potential neutralization arrangement for an electrostatic rotary atomizer having an bell rotatable in the region of a high-voltage field comprising, a stationary bearing unit for the shaft of the bell, with a part of said bearing unit having a fixed potential, and the shaft having an electrically conductive part connected to the shaft in an electrically conductive way being rotatable in said bearing unit, and a device for transferring electrical charge between the conductive part of the shaft and said fixed-potential part of said bearing unit, wherein said device for charge transfer is formed from at least one sharp edge projecting from at least one of the surface of the conductive part of the shaft and from a surface of said fixed potential part of said bearing unit running at least over one angular segment of said shaft part and said fixed potential part.
