发明名称 Reduced spin golf ball
摘要 A golf ball having a reduced spin rate is provided for minimizing the tendency of the golf ball to hook or slice in response to a sliding blow from a golf club. The golf ball may have a cover that is constructed to have a slippery surface such that when the club strikes the ball the club slides on the surface rather than imparting spin to the ball. In addition, the cover may be isolated from the inner core of the golf ball by an intervening lubricating layer which allows the cover to slip on the core so that any spin imparted to the cover is only minimally transferred to the core thereby minimizing spin of the golf ball. The golf ball may also be constructed with a fluid core either of a liquid or gelatinous substance which will not respond to any initial spin imparted to the outer cover of the golf ball and will thereby retard the spin rate of the ball.
