摘要: An apparatus for corona treating film includes a source of material and at least one transport roller that is rotatably mounted in frame. The has longitudinal axis width greater than the film. First second treater heads have first leading edges, trailing edges are parallel to axis. edge spaced from by predetermined distance. transported over high voltage electric arc provided heads. grounded provides return path current heads, thereby front side or back if third fourth used.
