Abstract
A game ball comprises an inflatable rubber bladder, a layer of windings over the bladder, panels of sponge rubber over the wound bladder, rubber channels between adjacent panels of sponge rubber, and panels of cover material over the panels of sponge rubber. Before the panels of cover material are applied, the bladder, sponge rubber, and channels are cured in a heated mold to bond the rubber channels and the sponge rubber to the wound bladder. After the panels of cover material are applied, the ball is heat molded to bond the cover material to the rubber channels and the sponge rubber.
