Golf balls with low spin rates.

摘要

A golf ball (10) with a low spin rate is made by covering the center (11) with a layer of uncured rubber (18), curing the rubber layer to make a rubber shell (18) about the center, and then winding elastic threads (20) about the cured rubber shell (18) to form a golf ball core. A golf ball cover (16) is then applied to the core (13) to form a golf ball (10). The center (11) is a liquid-filled hollow envelope. The thickness of the rubber shell (18) is between 0.16 cm and 0.64 cm.
