Patent ID: 7387504

Claim:
A mold for forming a cover for a golf ball, the mold comprising: a spherical cavity formed therein; hemispherical upper and lower mold cups being removably mated along a parting line that is distinct from the position corresponding to an equator line of the spherical cavity, each mold cup having a interior cavity detail, each mold cup having a mating surface forming the parting line; the mold creating a pattern of dimples on the cover of the golf ball, wherein at least one dimple lies across an equator of the ball; the mating surface of each mold cup comprising multiple radii forming a plurality of peaks and valleys: and the mating surface of each mold cup is a result of a superposition of a base waveform with a secondary waveform, whereby wavelength of the secondary waveforms are substantially shorter than that of the base waveform, wherein when the mold cups are assembled the parting line follows the dimple outline pattern and allows the dimples of one mold cup to interdigitate with the mating mold cup to form a golf ball with substantially seamless appearance.
