Golf ball and method for manufacturing the same

摘要

A method for manufacturing a golf ball includes the steps of forming the golf ball by using a mold, which mold includes at least two body parts, and is configured so that a cavity is formed within the mold by the joining of the at least two body parts, and in at least one of the body parts, a groove for forming a projecting land part which is ground after the formation of the golf ball is provided in a cavity wall surface near the entire circumference of a parting line formed by the joining; and performing treatment in which the golf ball formed by using the mold is treated so that the color of the entire land part of the golf ball is different from the color of dimples.

1. A method for manufacturing a golf ball, comprising the steps of:
forming the golf ball by using a mold, which mold includes at least two body parts, and is configured so that a cavity is formed within the mold by the joining of the at least two body parts, and in at least one of the body parts comprising: a plurality of protrusions for forming a plurality of dimples; a cavity wall surface for forming a land part of the golf ball; and a single groove for forming a projecting land part which is ground after the formation of the golf ball, wherein the single groove extends along the entire circumference of a parting line formed by the joining and has a bottom surface having a width between 0.2 and 10 mm and an opening having a width between 0.2 and 10 mm, and wherein the single groove has a cliff portion projected from an edge of the groove, the single groove being adjacent to one of the dimple-forming protrusion through the cliff portion which has a height to be ground; and performing treatment in which the golf ball formed by using the mold is treated so that the color of the entire land part of the golf ball is different from the color of the dimples.
