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).
A ball adapted to be projected to deviate from an expected trajectory, said ball having a spherical shape and comprising a first hemisphere and a second hemisphere, said second hemisphere having a hemispherical surface, wherein a first portion of said hemispherical surface has a generally smooth texture, and a second portion of said hemispherical surface has a generally rough texture, and wherein said ball is a simulated baseball, the surface of which is constituted by a first dumbbell shaped surface area and a second matching dumbbell shaped surface area, with a raised simulated seam connecting said surface areas, wherein said second portion is located within a bulbous end of one of said first or second dumbbell shaped surface areas and is one insert located symmetrically within said bulbous end.
A ball adapted to be projected to deviate from an expected trajectory, said ball having a spherical shape and comprising a first hemisphere and a second hemisphere, said second hemisphere having a hemispherical surface, wherein a first portion of said hemispherical surface has a generally smooth texture, and a second portion of said hemispherical surface has a generally rough texture and wherein said second portion is in the form of an insert flush with the hemispherical surface.
