Method of manufacturing a golf ball

Abstract

A golf ball is made by a process comprising: grinding a core of another golf ball into powder rubber in which more than 30% of particle is 0.8 mm or more in an average particle diameter, the another golf ball covered with one or more layers, in which 40 mass parts or less of metal salt of α,β unsaturated fatty acids is compounded to 100 mass parts diene rubber; preparing a core of the golf ball by kneading 0.1 to 30 mass parts of the powder rubber with a core material in which 40% mass parts or less of metal salt of α,β unsaturated fatty acids is compounded to 100 mass parts diene rubber; and covering the core of the golf ball with one or more layers.

What is claimed is:  
     
         1 . A golf ball made by a process comprising: 
 grinding a core of another golf ball into powder rubber in which more than 30% of particle is 0.8 mm or more in an average particle diameter, the another golf ball covered with one or more layers, in which 40 mass parts or less of metal salt of α,β unsaturated fatty acids is compounded to 100 mass parts diene rubber;    preparing a core of the golf ball by kneading 0.1 to 30 mass parts of the powder rubber with a core material in which 40% mass parts or less of metal salt of α,β unsaturated fatty acids is compounded to 100 mass parts diene rubber; and    covering the core of the golf ball with one or more layers.    
     
     
         2 . The golf ball according to  claim 1 , wherein an amount of the powder rubber compounded to the core material is 5 to 25 mass parts.
