CORONA GENERATOR FOR ELECTROSTATIC PRINTING

摘要

A corona generating device having a corona electrode supported between a pair of endblock assemblies, each endblock assembly defining a space for the passage of the electrode, and non-conductive inserts seated in the spaces in the endblock assemblies and surrounding the electrode. The non-conductive inserts are made of a material with high dielectric strength and resistent to corrosive atmosphere. The inserts can be easily and inexpensively replaced and they protect the endblock assemblies from effects of applying high voltages to the corona electrode.
