<P>PROBLEM TO BE SOLVED: To provide a sports ball capable of relieving the pain of the hands suffered from impact of the ball and having a soft feel and high flexibility. <P>SOLUTION: The sports ball comprises a rubber bladder (2) inflated with air injected into it, and a reinforcement layer (3) formed by winding a narrow adhesive-impregnated fabric tape (7) around a central spherical portion (6) of the bladder about each of the three axes of the bladder with the exception of opposite spherical end portions (5) of the bladder. The reinforcement layer is formed as orthogonal lap windings of the fabric tape over substantially all of the spherical surface of the rubber bladder, to provide a fabric tape wound ball, and the sports ball has surface panels (4) adhered with adhesive onto the reinforcement layer of the ball, after vulcanization and forming of the fabric tape wound ball. <P>COPYRIGHT: (C)2012,JPO&INPIT |
