ABSTRACT:
Disclosed is a method for coating a golf ball, wherein the coating efficiency of the paint is high and a uniform coating can be formed. According to the method, the paint is sprayed on a golf ball moving with rotation on the circumference of a circle having a diameter of 0.5 to 1.5 m from a disc charged with 60,000 to 130,000 V, which is rotating at 20,000 to 40,000 rpm and is inclined or moving in the vertical direction, or a paint is sprayed in a direction at an angle of 45.degree. or less to the horizontal direction from a disc charged with the above voltage, which is rotating at the above number of revolutions, to coat the golf ball so that a ratio of the maximum film thickness to the minimum film thickness may be 1.5 or less after one round of coating.
