Abstract
A method of making golf balls wherein an elastomeric spherical core is formed with a series of narrow shallow surface channels each lying on great circles passing through opposite pole areas, and similar hemispherical cover shells are compression molded upon the core and joined along a transverse seam lying in a plane that intersects all of the great circles, preferably at about 90.degree..
Claims5
A method of making a golf ball comprising the steps of providing a preformed homogeneous spherical core of elastomeric material having a multiplicity of relatively shallow surface channels all lying on the paths of great circles passing through opposite poles on said core surface and compression molding preformed hemispherical cover shells of thermoplastic or thermoformable material upon and about said core under heat and pressure, said shells being substantially centered with said poles as they are brought together to integrally weld around a generally transverse equatorial seam.
