Corona discharge processing apparatus

A corona discharge processing apparatus for treating a work having a surface of varying height by creeping corona discharge, comprising:

• a first electrode of at least one of a bar electrode and a rotary shaft-shaped electrode resiliently held against said work surface;
• a second electrode of at least one of a bar electrode and a rotary shaft-shaped electrode resiliently held against said work surface;
• and
• means for applying an electric charge of high frequency and high voltage between said first electrode and said second electrode to cause generation of a corona discharge between said electrodes along said work surface.

A corona discharge processing apparatus for treating a work by creeping corona discharge comprising:

• a first electrode resiliently held against a surface of said work;
• a second electrode resiliently held against said surface of said work spaced from said first electrode;
• and
• means for generating a corona discharge along said work surface between said first and second electrodes;
• wherein said first electrode is a bar electrode disposed upright to said work surface and supported as a fulcrum at an end remote from the work so as to incline upon contact with a work surface irregularity moving laterally against said electrode.
