Abstract
In connection with a golf ball comprising a core, an intermediate resin layer, and a cover, the invention provides a mold defining therein a spherical cavity for molding the resin layer. The mold is divided into a pair of mold halves each of which has at least three segments which are removably assembled to define the spherical cavity, each of the segments being provided on its cavity-defining surface with at least one projection. When the core is placed in the mold cavity, the projections support the core in place. The resin layer having perforations can be effectively molded and readily removed from the mold.
