Another disadvantage is that between the motor and these rotors, the disadvantage of these machines is that there is always either a gear 10 or a chain 10 on the remainder of the electrode jacket Due to this simultaneous rotation of the stick, so that the wires in front of the re-rotors and thus also the swash plates 3, an additional cleaning ^{process 6o} a rotation of the electrodes 5 about their own axis must go through At the same time, the surface of the elec- trode sheath from the wire is the nac Part of the fact that troden no longer touches the detached electrode jacket in the axial as well as in the radial direction.
