Abstract

The method of making a family of golf balls, each ball having substantially identical carry characteristics in both the pole and seam hitting modes and having between 300 and 600 dimples arranged on the spherical surfaces thereof, comprising the steps:

projecting a cubic octahedron (2) on the spherical surface of a said golf ball to provide four great circle paths (6) thereon defining six spherical squares (5) and eight spherical triangles (4) on the said surface;

placing a plurality of dimples in each said square and triangle without intersecting said dimples and said great circle paths; and

selecting the number of dimples in each said square and triangle such that the total number of dimples on said ball is a natural number satisfying one of the following formulae:

(4m×6)+(3n×8)

((4m+1)×6)+(3n×8)

(4m×6)+((3n+1)×8

((4m+1)×6)+((3n+1)×8)

where m is a natural number representative of the number of dimples within one spherical square and n is a natural number representative of the number of dimples within one spherical triangle.
