少ない。A solution is known from German Patent Application No. 27 21 370, which uses an electron-emitting device with a capacitor equipped with a discharge needle. There, an insulated conductor extends the entire length of the capacitor. The device is surrounded by an insulating jacket configured as a grounding part. An opening for a discharge needle is provided in the jacket. Experiments have shown that the device must be attached to both ends of the packaging sheet to be fully effective. There are very few cases where this can be achieved under the special conditions of the packaging machine.

シートの方向に加速するために、その近傍に補助電極が
配設される。German Patent No. 959,495 proposes a device having thin metal wires as electrodes. This metal wire is surrounded by a slitted metal tube. The slits are oriented towards the wrapping material sheet. An auxiliary electrode is disposed in the vicinity to accelerate the flow of ions in the direction of the packaging sheet.
補助電極は包装材シートと等しい電位を有する。The auxiliary electrode has the same potential as the wrapping material sheet.
包装材シート表面の電荷の極性と値は著しく変動するか
ら、この解決策は技術的に極めて実現困難である。補助
電極は不変の電位を有するから、連続的な確実な放電は
得られない。This solution is technically extremely difficult to implement, since the polarity and value of the charges on the surface of the packaging material sheet vary significantly. Since the auxiliary electrode has an unchanging potential, a continuous reliable discharge cannot be obtained.

Due to this unavoidable locational constraint of unavoidable proximity to metal parts, effective air ionization is not achieved.

Additionally, the device can be installed near metal members. This is either impossible or extremely ineffective with conventional ionization devices. According to the invention, sufficient air ionization is achieved to reliably neutralize even strongly electrostatically charged packaging materials of different polarities. A further advantage is that the construction of the present solution is compact and that it can be integrated particularly well directly into the area of the cumbersome working parts of the packaging machine. The structure of the present invention also eliminates the risk of electric shock.
