A method for coating a continuous band of material by application of an aerosol spray has an additional alternating current electrode creating a corona discharge

摘要

The band of material (2) is transported from a supply roll (1) to a take up roll (5) passing an AC electrode (8) extending the width of the band and a roller (3) to be charged by a DC electrode (9) and roller (4) before an aerosol spray (7). The corona discharge creates a chemical efect for a short period.
