  • Publication number: 20170080291
    Abstract: A golf ball comprises two generally hemispherical portions joined together at a parting line and comprising dimples on respective outer surfaces thereof. The parting line comprises a repeating pattern of curved segments alternating with straight segments. The parting line crosses a geometric equator of the golf ball, and wherein the parting line intersects at least one dimple bordering the equator. A mold for producing a golf ball is also described.
