CORONA DISCHARGE PROCESSING METHOD AND CORONA DISCHARGE PROCESSING APPARATUS FOR RESIN MOLDED PRODUCTS

摘要

Arrangement for applying a cerona discharge to a three dimensional plastic moulding (1) which has holes and corners (5,8,9,13) includes a discharge electrode (51) and a counter electrode (23), between which the moulding is held in a tensioning unit. The discharge electrode can be moved along the surface of the moulding, and its discharge section is spherical. A buffer plate made of a dielectric material is arranged over the holes in the counter electrode.
