Abstract:
A polyurethane golf ball cover containing an epoxy curing agent such as the diglycidyl ether of bisphenol A provides improved shear resistance over that containing a polyol curing agent.
Abstract:
This invention relates to methods of using cationic ionomers in golf ball cover compositions. Further, this invention relates to golf balls which have covers and cores and which incorporate urethane ionomers. The polyurethane golf ball cover has improved resiliency and initial velocity through the addition of an alkylating agent such as t-butyl chloride to introduce ionic interactions in the polyurethane and thereby produce cationic type ionomers.
Abstract:
The golf ball composition is comprised of a core with a compression of less than about 90 and a cover made from more than about 50 % of a sodium ionomer resin having a low flexural modulus and less than about 50 % of a lithium ionomer resin. The ball has very good performance and has excellent shear resistance.

Abstract:
A method of applying a coating material to an outer surface of a golf ball, the method comprising molding a golf ball having an outer dimpled surface under a pressure greater than ambient pressure within a mold cavity; formulating a golf ball coating composition; introducing a sufficient amount of the coating composition into the mold cavity between the golf ball outer surface and an inner surface of the mold cavity to substantially surround and coat the entire outer surface of the golf ball; curing the coating composition upon the ball's outer surface and removing the coated ball from the mold cavity.
Abstract:
An apparatus for the laser measurement of the shape of an object or foot (F) includes a base (16), a turntable (15), a linear slide (13), and a laser camera (40) which slides on the linear slide (13). The turntable (15) is attached to the base (16). The linear slide (13) is attached to the turntable (15) and extends from the turntable (15). The linear slide (13) moves with the rotation of the turntable. The laser camera (40) moves along and measures a first side and a second side of the object (F) in order to create a three-dimensional profile of the object (F) or foot shape. The apparatus further includes a robotic control and a computer. Apparatus provides a profile of the object or foot (F). The method also provides for the selection of a shoe size based upon the profile generated by the inventive apparatus.
Abstract:
A golf ball employing a cover composition comprising an oxa acid compound having Formula (I) wherein R is an organic moiety selected from the group consisting of alkyl, carbocyclic, and heterocyclic groups. Additionally, the present invention is directed towards a golf ball cover composition comprising a copolymer of at least two comonomers, the first comonomer comprising an oxa acid composition of Formula (I), and the second comonomer is selected from the group consisting of polyurethanes, epoxy resins, polyethyelens, polyamides, polyesters, and a monomers having a carboxylic acid moiety or its corresponding ionomer. Golf balls employing the present cover compositions exhibit excellent spin characteristics as well as good shear resistance.
Abstract:
The invention includes a method of manufacturing a golf ball by placing a golf ball core (42) into a preform mold cavity, injection molding a cover around the core (42), placing the resultant preform (56) into dimpled compression mold cavities (76, 78) and compression molding the cover to define a golf ball. The invention also includes injection molding a golf ball preform (56) into an outer non-dimpled elongated spherical shape having an elongate axis, and compression molding a spherical golf ball from the preform (56) in substantially spherical dimpled compression mold cavities (76, 78).
