Golf ball having balance rotation line and manufacturing method therefor

Abstract

A golf ball having a balance rotation line, wherein a balance rotation line is formed on an arbitrary line in which a point for marking the center of gravity of the ball is vertical to a joining line on the ball, thereby enabling accurate putting; and a manufacturing method therefor.

1 . A golf ball having a plurality of dimples and a joining line formed on an outer circumferential surface thereof, comprising:
 a marking point of the center of gravity formed and marked at a point on a surface of the golf ball to which a straight line passing through the center of the golf ball from the center of gravity thereof reaches; and   a balance rotation line formed on a perpendicular line which perpendicularly connects the marking point of the center of gravity and the joining line,   wherein when the marking point of the center of gravity is positioned at the joining line of the golf ball, the balance rotation line is formed perpendicular to the joining line, and when the marking point of the center of gravity is positioned at a pole of the golf ball, an arbitrary line among countless lines perpendicular to the joining line is selected to form the balance rotation line thereon.   
     
     
         2 . A method of manufacturing a golf ball on which a balance rotation line is formed, comprising:
 forming a marking point of the center of gravity to mark the marking point of the center of gravity at a point on a surface of the golf ball to which a straight line passing through the center of the golf ball from the center of gravity thereof reaches;   identifying a joining line to identify the joining line of the golf ball on which the marking point of the center of gravity is formed; and   forming a rotation line to form a balance rotation line on a perpendicular line which perpendicularly connects the marking point of the center of gravity and the joining line,   wherein when the marking point of the center of gravity is positioned at the joining line of the golf ball, the balance rotation line is formed perpendicular to the joining line, and when the marking point of the center of gravity is positioned at a pole of the golf ball, an arbitrary line among countless lines perpendicular to the joining line is selected to form the balance rotation line thereon.
