Definitions

Active discharge electrode to minimize positive and / or negative charges on moving material webs
the invention relates to an active discharge electrode according to the preamble of the main claim.
Discharge electrodes are known as passive discharge electrodes in the form of grounded tips or tongues in a variety of embodiments. There are also so-called active discharge electrodes that can be connected to a high-voltage alternating current source. They are used for unloading or removing the positive and / or negative charge on the surface of preferably rapidly moving material webs, such as are present for example in gravure printing.
Most of these known active discharge electrodes have at least several rows of needle-shaped individual electrodes arranged parallel to one another, which are arranged within a row parallel to one another with a tip at their free end and can be connected to a high-voltage source. At least one earth conductor is arranged along a row of electrodes, preferably parallel to it.
the invention is based on the object of designing an active discharge electrode in accordance with the preamble of the main claim in such a way that the greatest possible charge is possible with high-speed material webs and with the abovementioned plastics, in which a charge double layer can form.
the electrode according to the invention there is also the advantage in the event of a network failure that the row of individual electrodes act as passive discharge electrodes, so that at least a minimum of functionality remains Power failure persists.
This effect does not occur if the connections between the earth conductor and individual electrodes are interchanged, i.e. the earth conductor is attached to the high-voltage alternating current source and the needle-shaped individual electrodes are connected to earth.
the individual electrodes are applied to a voltage of the high-voltage alternating current source that is symmetrical with respect to the earth.
each individual electrode is connected to the high-voltage source via an ohmic resistor, this also results in an effective contactor which shows a schematic cross section through an active discharge electrode according to the invention.
the discharge electrode designated as a whole by 5
each individual electrode 8 is connected to the via an ohmic resistor 10 - Not shown - High-voltage source can be connected, which is an AC voltage source.
ground conductors 11 are provided, which are circular in cross section and can be formed, for example, as a wire. These two earth conductors run at right angles to the extent of each individual electrode 8 and parallel to the plane 9, in which the individual electrodes of a row are arranged. Each conductor is surrounded by an electrical insulator 12.
