METHOD AND DEVICE FOR ELECTROSTATIC CHARGING

摘要

The invention relates to a method for electrostatically charging the two surfaces of at least one web with a charge of opposite polarity, before this at least one web is processed further. According to the invention, the web is fed through the gap between a pair of rollers, said rollers being positioned parallel with each other and a short distance apart from each other. The invention is characterised in that the two surfaces of the at least one web are electrostatically charged by means of rollers in the gap between said rollers.
