摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a multi-piece golf ball capable of forming an outer layer that can be easily aligned with a core while having a practically sufficient strength, and capable of accurately forming the core and the outer layer into respective desired shapes.;SOLUTION: The method for manufacturing the multi-piece golf ball includes the process of forming the outer layer 3b made from a rubber composition on the surface of the core 4 by forming a pair of semi-vulcanized, hemispherical outer layer pieces 3a and 3a' at the same time, then inserting the separately formed core 4 between the pair of outer layer pieces 3a and 3a', causing the open edges of the outer layer pieces 3a and 3a' to abut against each other, and vulcanizing the outer layer pieces 3a and 3a' by press molding.;COPYRIGHT: (C)2003,JPO
