Abstract
A corona treatment system (10d) has a corona treatment generator (11d), a first stationary electrode (12d) having a dielectric layer (18d) disposed thereon and a second roller electrode (13d) spaced from the first stationary electrode (12d) by a gap (15d). The second roller electrode (13d) has a layer of dielectric material (19d) disposed around a core (23d) and has a conductive layer (24d) disposed over a substantial portion of a length of the second roller (13d). A switch (20) is electrically connected between the conductive layer (24d) and an electrical ground, and the switch (20) is operable to switch the system between a grounded web mode and a dual dielectric mode.
