ABSTRACT:
A spherical ball, for projection through the air to deviate from an expected trajectory, has a first hemisphere (12) and a second hemisphere (14). The surfaces (52, 54) of the first hemisphere (12) and the second hemisphere (14) are generally smooth, except for the provision of a simulated seam (53) which gives the ball the appearance of a baseball. An insert (40) of felt-like material is provided in the second hemisphere (14) with the surface of the insert (40) flush with the surface (54) of the hemisphere (14). When the ball is projected along the plane of the line (16) between the hemispheres (12, 14), it will deviate from that plane in the direction of the first hemisphere (12). The ball is manufactured by locating the insert (40) in a mould (60) and injecting polyurethane foam (64) into the mould (60) with the insert (40) bonding with the foam, (64).
