Abstract: The present invention is directed to a method of forming plurality of golf balls comprising steps of: providing plurality of inner cores; forming sheet of uncured rubber; forming plurality of preps in the sheet of uncured rubber such that each prep contains a concave top surface and is detachably connected to coupling material; loading the preps and coupling material into a core mold; loading plurality of inner cores into mold such that the inner cores are aligned with the concave surface of each prep; molding the preps about the inner cores to form outer core layers; and forming covers about outer core layers.

Abstract: Method of making an inventive golf ball incorporating a novel compression molded outer layer comprised of inventive first and second half-shells that are molded from preforms of extrudate, each preform created using a novel flying knife such that a cross-sectioned face of the preform has a curved depth which may be up to 20% greater than the depth of a preform created using a conventional straight edge and/or straight-faced flying knife. In one embodiment, the subassembly of the golf ball is a rubber spherical inner core, and the inventive compression molded outer layer is a rubber outer core layer. In a specific such embodiment, the rubber of the inner core and the rubber of the outer core layer differ.

Abstract: The present invention is directed to a method for forming golf balls, wherein an extruder forms a continuous tubing of cover material and a continuous stream of golf ball cores are fed into the tubing and translated to an encasement station wherein the tubing/cover material is wrapped around each core and the encased core sealed off by a twisting or crimping procedure. The resulting product is placed into a compression mold and a two piece golf ball can be created without the need for the costly process of injection molding.
