Abstract
The invention concerns an active discharge electrode (5) for minimizing positive and/or negative charges on moving material webs. The active discharge electrode (5) comprises a plurality of needle-shaped individual electrodes (8) which are disposed mutually parallel and can be connected to a high-voltage source, preferably a high-voltage transformer. The active discharge electrode (5) further comprises at least one earthing conductor (11) extending at right angles to and along the plurality of individual electrodes (8).
