Abstract (en)

The charging electrode (1) has casing and a number of parallel needle points (7) arranged on the casing which are made up of electrically conducting material. A conductor (12), connected to needles (4), is led out for supply of electric current. A flow channel (8) is aligned with holes present laterally on casing and needle. The flow channel is connectable, through an opening (11), to a source of compressed air. Independent claims are also included for the following: (A) Electrode for a rotary printing machine; and (B) Electrostatic pressure assistance.
