Abstract
In a golf ball of the icosahedral dimple arrangement pattern having twenty identical phantom regular triangles projected on its spherical surface, all dimples are arranged within the triangles such that no dimples may intersect the sides of each triangle and a great circle which does not intersect the dimples at all may not be depicted. Some dimples may be arranged at the apexes of each triangle. The golf ball travels a longer distance and provides consistent flight independent of impact points. Also provided is a mold consisting of upper and lower mold cups whose cavity surface is provided with dimple-forming protrusions such that the inventive dimple arrangement may be accomplished. The mold is easy to design and fabricate.
