Patent ID: 6866802

Claim:
A method of forming a golf ball comprising: forming a non-coated mold cavity; providing within the mold cavity a vent pin and a vent surrounding the vent pin; roughening the surface of the mold cavity to an average roughness of about 10 to about 200 microinches to form peaks and valleys wherein the valleys form a pattern of interconnected passageways in fluid communications with the vent pin wherein the roughness is sufficiently large enough to create adequate passageways to accommodate an air flow, yet small enough and shaped appropriately so that a cover material cannot enter the passageways sufficiently to prevent gases from traveling on a short path from a flow terminus to the vent surrounding the vent pin; and removing any abrasive agent or removed mold material from the roughened surface of the mold cavity; forming a golf ball component in the roughened non-coated cavity.
