Abstract

The invention relates to a device for minimising positive and/or negative charge formation on the surface of a plastic component. Said invention comprises a number of electrodes of differing polarity, which are formed from wire ends arranged in pairs a set distance from each other and/or as a single conductor in electrodes arranged with bipotential polarity and which act upon various surface segments or parts thereof. The inventive method permits a reliable, space saving and economic neutralisation of the electrostatic charge on the plastic component, which guarantees the highest possible degree of purity.
