ABSTRACT:
A method and apparatus for providing uniform corona bonding between and across the width of a plurality of layers of material each having a generally uniform thickness and width whereby, if desired, the plurality of layers may be easily and uniformly separated. Uniformity of bond is achieved by configuring the outer ends of an otherwise straight electrode, placed at an optimum effective bonding position, in proportion to the higher corona energy levels found to occur at the ends of the corona electrode bar.
