Publication number: 20100151971Abstract: 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.Type: ApplicationFiled: December 17, 2008Publication date: June 17, 2010Inventors: Thomas L. Mydlack, Ajay Vora, Robert A. Wilson
