Abstract: The present invention relates to a golf ball cover composition comprising: a) from about 45 to 55 weight percent of a first high acid ionomer having an acid content of about 19 weight percent and, b) from 55 to 45 weight percent of an ionomer selected from the group consisting of i) a second high acid ionomer having acid groups neutralized with a different metal ion than said first high acid ionomer, and ii) an ionomer containing about 15 weight percent acid groups.

Abstract: The present invention is directed to golf balls which have a lift to weight ratio greater than 1 when the ball is hit at a speed of 150 ft/sec and a spin rate of 3,000 rpm to enhance the lofting time of the ball and thereby provide the golfer with a slow swing speed increased distance and improved trajectory. The golf ball has a core and a cover. The cover has dimples ranging in number from 100 to 1,000 and having a total volume of less than 1.5% of the ball volume on its exterior surface. The dimples have diameters between 0.04 and 0.3 inch and depths between 2/1,000 and 20/1,000 of an inch. The golf ball weight ranges from 1.35 ounces (38.3 grams) 1.55 ounces (43.97 grams). The cover material has a flexural modulus of less than 65,000 p.s.i.

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 or zinc ionomer resin having a softening termonomer and a flexural modulus of less than about 10,000 psi and less than about 50% of a lithium ionomer resin. The ball has very good performance and has excellent shear resistance.

Abstract: A method and apparatus for making a golf ball of selected instruction having an encapsulated core or a non-treated core and a polyurethane cover of selected composition in which equipment is employed for aligning, centering and locating the core in relationship with the molding of the cover thereon.
