Mold and method of molding golf ball having dimples on the equator
First Claim
1. A golf ball mold for applying a dimple arrangement to a pre-molded sphere, the mold comprising:
- at least three inserts in contiguous engagement with each other and removably mated along multiple parting lines;
each insert having a spherical cavity surface to define a spherical cavity for receiving the pre-molded sphere;
a plurality of dimple forming projections defined in the spherical cavity surfaces of the inserts; and
the pre-molded sphere of a net size and weight similar to the finished golf ball.

Abstract
A method and mold for making a multi-parting line golf ball by compressing a dimple arrangement about a pre-formed sphere. The mold comprises at least three mold inserts having dimple producing projections on their inner spherical surfaces. Upon the dimples being molded to the pre-formed sphere, the resulting parting lines which are offset to the equator of the sphere, are visually inconspicuous, due to the pre-formed sphere being of a net size and weight very similar to the finished golf ball. The method of the invention allows for dimples to be located at and on the equator of the ball.

14. A method of molding a golf ball having multiple parting lines, the method comprising the steps of:
-
(a) providing a plurality of mold inserts, each insert having a spherical cavity surface for defining a spherical cavity having a plurality of dimple forming projections therein;
(b) providing pre-molded spheres of a net size and weight of the golf ball;
(c) loading the pre-molded spheres into the spherical cavity;
(d) forming a cover with a plurality of dimples; and
(e) imparting multiple parting lines. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
