Abstract
The present invention is directed to a golf ball having a non-planar parting line on its spherical surface.
Claims8
A golf ball having a non-planar parting line and comprising a plurality of dimples located adjacent to the parting line, wherein:
- the parting line comprises a plurality of main arcs, each main arc being selected from concentric arcs and non-concentric arcs,
- for each concentric arc, the radius, rARC, of the arc relates to an adjacent dimple having a diameter, DDIMPLE, such that

- and
- for each non-concentric arc, the radius, rARC, of the arc relates to an adjacent dimple having a diameter, DDIMPLE, such that

- and
- the plurality of dimples located adjacent to the parting line consists of a first portion of dimples and a second portion of dimples, each dimple of the first portion having a wave relief distance of from 0.001 inches and 0.005 inches, and each dimple of the second portion having a wave relief distance of 0.008 inches or greater, where wave relief distance is measured as the shortest distance from the average dimple diameter of the dimple to the parting line.
