摘要： 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.

摘要： In a golf ball having at least a set of large and small diameter dimples, the large and small diameter dimples are of the same cross-sectional shape in their lower portion. A master model is prepared by feeding a cutter into a hemispherical surface of a master block to different depths while rotating the cutter, thereby forming a set of large and small recesses, respectively, wherein the large and small recesses have the same cross-sectional shape. The master model having plural types of dimples can be briefly fabricated and has increased freedom of design. Using the master model, a golf ball featuring uniform and densely distributed dimples can be manufactured.

摘要： Using a mold having typically two split mold segments which are mated in a separable manner to define a spherical mold cavity therein, a golf ball having a multiplicity of dimples in its surface is molded by feeding a molding material into the mold cavity. The mold is split along a line off a horizontal great circle of the golf ball into two split mold segments having different areas of contact with the ball. The golf ball as molded is always caught and left in the larger mold segment and thus can be easily removed from the mold by a routine operation.

摘要： The present invention provides a golf ball of improved symmetry by regulating volume, area, edge length and array symmetry indexes Vi, Si, Li, and Ni obtained from coordinates (.theta.j, .phi.j) of a dimple center as represented by the latitude (in radian) and longitude of the ball and a radius rj and a volume vj of a dimple, for correcting a difference in dimple effect caused by a distortion of roundness of the ball. The golf ball does not have dimples which intersect the mold parting line, and the dimples occupy at least 65% of the ball surface.
