Abstract

A device for electrostatically charging or discharging material surfaces in the form of continuous strips or individual formats, in particular for electrostatically charging photoelectrically conductive insulating layers, with pointed electrodes and a rotating cylinder, characterized in that the suction electrode, surrounded by an insulating body, consists in a rotating cylinder, the surface of which is sprayed, and is located between effluvium-emitting electrodes in the form of rows of needles in which the needles are a short distance from each other, which are protected outwards by insulating bodies, the line being upper generatrix of the aspirating electrode at approximately the same height as the tips of the needles, a line parallel to the material to be treated, and because there is preferably a counter electrode with the same electrical potential as the aspirating electrode.
