ABSTRACT:
A pair of semispherical molds, each having dimple-forming projections on a connecting portion is used to shape a resinous material into a golf ball having dimples on a seam corresponding to the connecting portion. A ball fixing means is utilized to hold the golf ball thereto with the seam uncovered. A cutting member disposed at an end of a rotary shaft, and having a radius of curvature smaller than a sectional radius of curvature of the dimple is utilized to remove a burr from the seam of the golf ball. The rotary shaft rotates on its axis and moves forward when the cutting member is brought into contact with the dimple on the seam and backward when the cutting member is brought into contact with a convex land portion. The cutting member is then pressed against the seam successively in alternate contact with the dimples and the land portions.
