Abstract
A geometric-shaped core ( ) for a golf ball ( ) has a plurality of outwardly extending projections ( ) formed on a spherical central portion thereof. A layer ( ) of a relatively less resilient material is applied in the interstitial space between the projections ( ) on the surface of the core ( ), and a cover ( ) is applied over the core ( ) and interstitial layer ( ). The geometric-shaped core ( ) is manufactured by first providing flexible, resilient, honeycombed inserts ( ) to be used in a conventional compression mold ( ). The inserts ( ) are placed into the upper and lower mold cavities ( ), the core material ( ) is added, and the geometric-shaped golf ball core ( ) is compression molded.
