ABSTRACT:
A transparent game ball particularly useful as a billiard or pool ball is disclosed, along with manufacturing processes and apparatus for producing the ball. The ball includes a weighted opaque object centered within the transparent spherical outer covering of the ball for providing the required weight for the ball as well as a desirable appearance. The transparent portion of the ball is produced bubble free of polyester resin through the use of a special, two-piece mold for forming the entire ball at one time. Into this two-piece mold a centering spider or disk of the same rigid polyester resin is inserted. The spider or disk may be either transparent or opaque, and is used to precisely center the opaque weighted object at the ball's geometric center.
