Abstract
The present invention relates to a method of manufacturing a painted golf ball with reduced static electricity on the surface of the golf ball prior to painting to allow even painting to produce a ball without asperity on the surface, characterized by irradiating the surface of the golf ball, which is positively charged before painting, with negative ions directly before painting. Preferably, the surface of the golf ball after the irradiation with negative ions and prior to the painting is negatively charged, and particularly, the surface of the golf ball after the irradiation with negative ions prior to the painting is preferably charged at −0.1 to −40 kV.
Claims11
A method of manufacturing a golf ball including the steps of:
- providing a golf ball having a positively charged surface;
- irradiating the surface of the golf ball, with negative ions;
- and
- applying at least one layer of paint to the surface of the ball immediately after the step of irradiating;
- and wherein
- the surface of the golf ball after the irradiation with negative ions and prior to applying at least one layer of paint is charged at −0.1 to −40 kV.
A method of manufacturing a golf ball including the steps of:
- providing a golf ball having a positively charged surface;
- irradiating the surface of the golf ball, with negative ions;
- applying at least one layer of paint to the surface of the ball immediately after the step of irradiating;
- and
- using a blower to generate a flow of air to carry the negative ions to the surface of the golf ball.
