Abstract
The invention provides a golf ball manufactured using a mold having a top half and a bottom half, which ball has formed on a surface thereof, near a seam line corresponding to a parting line between the top and bottom halves of the mold, a recessed and/or raised mark serving as an indicator for detecting the direction or position of the seam line. The invention also provides a golf ball mold composed of a top half and a bottom half that detachably join together so as to form therein a spherical cavity into which a material is injected to mold a golf ball, which mold bears, near a parting line between the top and bottom halves on a wall of the cavity, a raised or recessed feature for forming a mark as an indicator for detecting the direction or position of the parting line. The invention enables the direction and position of the seam line on the surface of the ball to be easily identified and enables the subsequent steps of visually inspecting the ball and applying indicia to the surface of the ball to be carried out more smoothly and advantageously, making it possible in particular to greatly shorten the time devoted to these operations.
