Abstract
A geometric-shaped core (12) for a golf ball (10) has a plurality of outwardly extending projections (14) formed on a spherical central portion thereof. A layer (22) of a relatively less resilient material is applied in the interstitial space between the projections (14) on the surface of the core (12), and a cover (24) is applied over the core (12) and interstitial layer (22). The geometric-shaped core (12) is manufactured by first providing flexible, resilient, honeycombed inserts (42) to be used in a conventional compression mold (30). The inserts (42) are placed into the upper and lower mold cavities (30), the core material (40) is added, and the geometric-shaped golf ball core (12) is compression molded.
