Patent ID: 7070726

Claim:
A process for forming a cover layer for a golf ball, said process comprising the steps of: providing an intermediate ball including a core; providing a reaction injection molding apparatus having a generally spherical molding chamber with a molding surface defined by (i) a plurality of first raised regions for forming a plurality of dimples on said cover layer, each of said first raised regions having a first height, and (ii) a plurality of second raised regions, each of said second raised regions having a second height greater than or equal to the thickness of the cover layer, and an assembly for administering a flowable material into said molding chamber; providing to said molding apparatus a plurality of flowable reactants suitable for forming said cover layer for said golf ball; positioning said intermediate ball within said molding chamber such that said plurality of second raised regions of said molding surface contact and retain said intermediate ball within said molding chamber; and administering said flowable reactants into said molding chamber and generally between said intermediate ball and said molding surface to thereby cure said flowable reactants and form said cover layer, wherein said cover layer has said plurality of dimples and a second plurality of dimples defined by said plurality of second raised regions.
