Abstract

Procedure to de-electrify insulating materials, such as plastic material films, which consists of producing positive ions and negative ions in the vicinity of the film that passes by corona discharges, characterized in that the signal that causes the formation of these ions is constituted by an alternative wave of high power that has a strong energy gradient, prolonged by an alternative wave, of lesser amplitude, the frequency of the signal being sufficiently high so that the speed of discharge is compatible with the speed of the film.
