Apparatus for manufacturing a golf ball |
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.
