Abstract
A golf ball having a plurality of dimples arranged on its surface is provided wherein the ball surface is free of a great circle that does not intersect with dimples, at least 7% of the total number of dimples are non-circular dimples, and some non-circular dimples lie across the equator of the ball corresponding to a parting plane of a mold. The ball is improved in flight distance and aerodynamic uniformity.
Claims6
A golf ball having a plurality of dimples arranged on the surface thereof and an equator which is in substantial alignment with a parting plane between a pair of mold sections in which the ball has been molded, wherein
- the ball surface is free of a great circle that does not intersect with dimples, and at least 7% of the total number of dimples are non-circular dimples, at least one of which lies across the equator.
A golf ball prepared by molding in a mold comprising a pair of mold sections which are removably mated along a parting plane in alignment with an equator of a spherical cavity to define the spherical cavity, the ball comprising a core, an optional intermediate layer, and a cover having a plurality of dimples on the outer surface thereof, wherein
- the plurality of dimples include at least one non-circular dimple and generally circular dimples which are shaped by the tip of support pins of circular cross-section disposed near a pole of the cavity for retraction in a direction perpendicular to the paring plane.
