Abstract
The stain preventing cover is formed from a composite sheethaving a three layer structure as a raw material which is produced by laminating a first sheet materialhaving a low dielectric constant and having insulation performance, a second sheet materialhaving a dielectric constant higher than that of the first sheet materialor having semiconductivity and a third sheet materialhaving a dielectric constant lower than that of the second sheet materialand having insulation performance, in which an end of the second sheet materialis positioned together with an end of the first and third sheet materialsandadjacent to a electrostatic high voltage partof a coating machine and another end thereof is positioned distant from an earth partof the coating machine to be electrically insulated. The influence of the disturbance of the electric potential distribution on the surface of a coating machine main bodyis alleviated by the first and second sheet materialsandto cause the electric potential distribution on the surface of the third sheet materialto be homogeneous to thereby preventing the attaching of atomized coating particles to the surface.
