摘要： An apparatus for removing the burr from the seam of a golf ball made using a pair of semispherical molds each having dimple-forming projections on a connecting portion to shape resin into a golf ball having dimples on a seam corresponding to the connecting portion. A ball fixing mechanism holds the golf ball thereto with the seam uncovered. A cutting member having a cutting member, disposed at an end of a rotary shaft, having a radius of curvature smaller than a sectional radius of curvature of each of the dimples. The rotary shaft rotates on its axis and moves forward when the cutting member is brought into contact with each of the dimples on the seam and backward when the cutting member is brought into contact with a convex land thereon. Thereafter, the cutting member is pressed against the seam successively removing the burr while maintaining the integrity of each of the dimples.

摘要： A golf ball has dimples arranged in eight spherical equilateral triangles obtained by projecting, on the imaginary spherical surface of the golf ball, the ridge lines of a regular octahedron inscribing the imaginary spherical surface. Three great circles corresponding to the ridge lines being projected on the spherical surface. One great circle coinciding with a mold seam is formed as the sole great circle unintersecting dimples and the other two great circles intersect dimples. Between 300 to 550 dimples are formed in the golf ball with the dimples being equivalently arranged in each of the eight spherical equilateral triangles.
