METHOD FOR PAINTING GOLF BALLS
The present invention relates to a method for painting dimpled golf balls that are moving along an endless conveyor. The method employs paint guns operating at a relatively low atomizing air pressure, and make contact with the golf ball surface at an angle between about 5° to 60°. The paint guns are continually in the on position and the paint neither coagulates in the gun nozzle nor forms puddles in the dimple cavities. The number of golf ball painted per gallon of paint is dramatically increased as is the number of ball painted per time period.
1 . A method for applying a coat of paint on a golf ball, the method comprising:
providing an endless conveyor within an enclosed paint booth, the conveyor supporting a multitude of open sided spindle cups;
placing a golf ball in each spindle cup;
rotating the golf ball when in position to be painted;
providing two continuously spraying paint guns operating at a relatively low atomizing spray pressure;
directing the continuously spraying paint guns at angles to a surface of the rotating golf ball; and
spraying the paint at the rotating ball while maintaining a constant flow of paint and a constant movement of the conveyor; and
curing the ball.
2 . The method according to claim 1 , wherein the paint gun angle to the golf ball surface is about 5° to 60°.
3 . The method according to claim 2 , wherein the paint gun angle to the golf ball surface is about 28° to 40°.
4 . The method according to claim 1 , wherein the ball rotates between about 300 to 500 rpm.
5 . The method according to claim 1 , wherein one paint gun is an upper paint gun and the other is a lower paint gun.
6 . The method according to claim 1 , wherein the atomizing air spray pressure is equal to or less than 6 psi.
7 . The method according to claim 1 , wherein the paint guns do not cycle on and off.
8 . The method according to claim 1 , wherein a multitude of golf balls move on the conveyor at a rate of 200 per minute.
9 . The method according to claim 8 , wherein the golf balls on the conveyor are on a center line of 2 inches from each other.
10 . The method according to claim 9 , wherein the method provides for the application of a coating of more than 12,000 golf balls per gallon of paint.
11 . The method according to claim 9 , wherein the cover is about 0.030 inch thick.
12 . A golf ball having a coat of paint applied to a cover surface, wherein the coat of paint is spray coated on the surface at an air pressure equal to or less than 6 psi.
13 . The golf ball of claim 12 , wherein the coat of paint is applied to the cover surface at an angle between about 5° to 60°.
14 . The golf ball of claim 13 , wherein the coat of paint is applied to the cover surface at an angle between about 32° to 40°.
