Abstract:
1. A sports ball, comprising: a spherical hollow rubber bladder inflated with air injected into it, and about each of three axes of the spherical rubber bladder, a narrow adhesive-impregnated fabric tape wound around a central spherical portion of the rubber bladder, with the exception of opposite end portions of the rubber bladder to form a fabric tape reinforcement layer, wherein: the fabric tape reinforcement layer consists of three mutually orthogonal lap windings of the fabric tape to provide a fabric tape wound ball core, in each one of the three fabric tape lap windings, each of the adjacent lap portions of the wound fabric tape has its edge positioned to be parallel to an edge of its adjacent lap portion, and in each one of the three fabric tape lap windings, each of the adjacent lap portions of the wound fabric tape has its edge positioned to overlap its adjacent lap portion at all points by one-half of a width of the fabric tape, such that the mutually orthogonal lap windings around the central spherical portion of the rubber bladder with the exception of opposite end portions of the rubber bladder form four layers of fabric tape over substantially all of the spherical surface of the rubber bladder.
