  • Patent number: 7645203
    Abstract: A carcass of a soccer ball or other inflatable game ball has a bladder with a valve for introducing air into said bladder; a fabric pocket layer located outside said bladder composed of a plurality of fabric pieces sewn to form a spherical shape, with a hole for the valve, the sewing thread for sewing said fabric pieces and the sewn margin being located in the inner side of said fabric pocket, and an opening being cut for reversing and placing the bladder being located on one of the fabric pieces; and an opening-cover adhered solidly on said opening for enclosing said opening. The surface of the manufactured ball is soft, with good tactility and the performance of ball-controlling is good. At the same time because there is no sewn margin left on the out side of the fabric pocket layer, no slight unevenness will exist on the surface of the fabric pocket layer, the ball will have a substantially perfect spherical shape, and can be easily controlled by athletes during a game.
