Abstract
The present invention relates to golf balls and in particular to an improvement in wound golf balls, especially those which have a liquid center. By using a two-storage winding process, breakage of threads about the center is reduced. The two-stage process uses a first step of winding at low tension followed by a second step of winding at high tension. The low tension winding is done at a tension which is at least 20% less than the tension used in the high tension winding step. The low tension winding step is employed for a period of time between 11/2 to 18 seconds.
