- the different electrode groups 39a, 39b are supplied with antiphase AC high-voltage signals 13a, 13b in such a way that the first electrode group 39a becomes with the first AC high-voltage signal 13a and the second electrode group 39b with the one for the first AC high-voltage signal 13a is applied to the opposite-phase second AC high-voltage signal 13b.
- FIG. 12a shows a perspective view of components of an eighth embodiment of a plasma treatment device 1 according to the invention with two electrode groups 39a, 39b, which are acted upon by alternating high-voltage signals 13a, 13b.
- Figure 12b) shows a longitudinal section of the components shown in Figure 12a).
- the electrode arrangement 5 in this eighth embodiment of the plasma treatment device 1 has two distributor disks 41 a, 41 b, to which antiphase alternating high-voltage signals 13a, 13b are supplied.
- the first distributor disk 41a is with the electrodes 3 of the first electrode group 39a connected and the second distributor plate 41b is connected to the electrodes of the second electrode group 39b.
- the different electrode groups 39a, 39b can be supplied with different high-voltage signals, namely with the antiphase alternating high-voltage signals 13a, 13b.
- the distributor disks 41 a, 41 b in this eighth embodiment are not arranged in the same plane, but in different planes.
- the distributor disks 41 a, 41 b are arranged one behind the other as seen from the contact surface 27.
- the second distributor plate 41 b is an inner distributor plate and the first distributor plate 41 a is an outer distributor plate.
- the second distributor plate 41 b is arranged between the first distributor plate 41 a and the bristle field 17.
- the inner second distributor plate has a plurality of through holes 81 through which the electrodes connected to the outer first electrode 41 a extend.
