ABSTRACT:
A golf ball has one great circle and four one-half great circles which all intersect no dimples. Eight end points which include two end points of each one-half great circle are formed at the one great circle. These end points do not coincide with each other on the great circle. One of the one-half great circles intersects the other one-half great circle at a right angle at the middle point thereof on each of the great circle. In other words, an upper semispherical mold for an octahedral dimple golf ball arrangement is rotated a certain angle relative to the lower mold such that two of the three great circles are divided into four one-half great circles. The parting line of the mold becomes the one remaining great circle. In this manner, a more uniform flight of the golf ball canbe obtained regardless of whether the ball is hit on a seam, semi-seam of non-seam area.
