Mold for a golf ball

摘要

A golf ball mold having a non-planar parting surface formed by superimposing a base waveform with a least one shorter secondary waveform. The base waveform is defined by a series of concentric arcs wherein adjacent arcs are connected with a straight line segment that is tangent to the arcs and creates an acute angle. The length of the straight line segment being critical to the accuracy and predictability of the parting line.
