Sports ball with floating cover |
摘要 |
A game ball includes an inflatable bladder and a floating cover which can move relative to the bladder. The bladder is surrounded by a cloth liner which serves to retain the shape of the bladder. A second bladder or layer of elastomeric material surrounds the cloth liner and is movable relative to the cloth liner. A second cloth liner surrounds the second bladder, and the cover is adhesively attached to the second cloth liner.
