Abstract
A corona discharge treatment apparatus or system and method for treating both insulating and conductive surfaces including a ground member and a plurality of flat electrodes aligned flat side in a row and each electrode having at least one finger-like protrusion with a pointed tip having a radius in the range of about 0.010 to about 0.125 and operating in a high kilo frequency range of about 20k Hz to 30k Hz. The electrodes are individually rotatably mounted to move to and away from the ground member so that the row length of the electrodes can be adjusted to be the same dimension as the width of material to be treated or to only treat selected portions of the material.
