Method of manufacturing a sport ball |
摘要 |
A sport ball may include a casing and a bladder. The casing may form at least a portion of an exterior surface of the ball. The bladder may be located within the casing and formed from a plurality of polymer bladder elements joined along abutting edges to form a sealed and valveless structure that encloses a pressurized gas. In some configurations, the bladder may be at least partially formed from an ether-based thermoplastic polyurethane material. |
