Abstract:
There is provided a sports ball capable of relieving the pain of the hands suffered from impact on the ball and having a soft feel and high flexibility. The sports ball comprises a spherical hollow rubber bladder (2) inflated with air injected into it, a fabric tape reinforcement layer (3) formed by winding a narrow adhesive-impregnated fabric tape (7) around a central spherical portion (6) of the rubber bladder about each of three axes of the rubber bladder with the exception of opposite spherical end portions (5) of the rubber bladder, whereby the fabric tape 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 core, and surface panels (4) adhered with adhesive to the fabric tape reinforcement layer on the rubber bladder, after vulcanization and forming of the fabric tape wound ball core.
