Abstract

See full text

A multi-layer golf ball includes a core, an intermediate layer surrounding the core, and a cover layer surrounding the intermediate layer. The core defines an outer surface that includes a plurality of polygonal land portions substantially aligned on a common sphere, which has a diameter of between 22 mm and 32 mm. The intermediate layer has a radially inward-facing surface that is flush with the outer surface of the core, and has a radial thickness of between 4 mm and 9 mm. The outer surface of the core defines a first set of annular grooves disposed about a first axis, and a second set of annular grooves disposed about a second axis. Each of the first and second set of annular grooves extend radially inward from the common sphere, and the first axis and the second axis are orthogonal.
