Abstract
A three-piece thread wound golf ball including a central solid core portion composed mainly of polybutadiene having a Shore D hardness of 55-75 and increased diameter (34.3-38.1 mm) and reduced specific gravity (1.20-1.25) compared to traditional three-piece wound golf balls. The solid core portion is wound with an elastomeric thread material to achieve a core and winding layer diameter of 39.1-40.6 mm. A dimpled cover portion formed of a thermoplastic material overlies the winding layer. The three-piece thread wound golf ball construction provides desirable increased moment of inertia and spin characteristics for the ball. The resulting golf ball characteristics are such that when hit with a driver, other woods or the longer iron clubs it performs like a distance two-piece golf ball; when hit with mid-iron clubs it performs like a two-piece Hi-spin or a soft covered multi layered golf ball; and when hit with short iron clubs it performs much like a Balata wound golf ball.
