Patent ID: 7278932

Claim:
A method for arranging dimples on a golf ball, the golf ball geometrically defining a ball center and a spherical surface having a pair of poles and an equator, by which the ball is divided into a pair of hemispheres, and an axis passing the poles and the ball center, the method comprising the steps of: drawing a plurality of imaginary lines connecting one pole and the equator and extending perpendicular to the equator on one hemisphere to divide the hemispherical surface into a plurality of spherical isosceles triangle regions, arranging a plurality of dimples within spherical isosceles triangle regions adjoining along one imaginary line of the imaginary lines such that the dimples in the triangle regions are in axial symmetry with respect to said one imaginary line, rotating the dimples about the axis such that the dimples arranged close to the pole are rotated about a smaller angle than are the dimples arranged closer to the equator; wherein some of the dimples arranged adjacent to the equator lie across the equator.
