<p>Method and apparatus for charging filaments moving along a path wherein the filaments are passed across the face of a target electrode in a sheet of moving air and a plurality of corona discharge electrodes arranged in a row extending in the direction of filament travel apply an electric charge to the filaments to separate them. The corona discharge electrodes are positioned along the filament path between the point where the filaments impinge the target electrode and the point where the air stream velocity has decreased to about the velocity of the filaments.</p>
