<p>A stitchless fabric covered ball e.g. a tennis ball, having a uniform surface free of adhesive seams or other irregularities is disclosed. The ball has a hollow spherical core made from an elastomeric material, and a plurality of fabric panels (14) secured to the core by means of an adhesive. The panels secured to the core substantially cover the entire core so that the edges of the panels are substantially in continuous abutment (20) to form a substantially continuous fabric covering uninterrupted by adhesive seams. The ball has uniform radial symmetry which provides for more predictable and uniform aerodynamic and bounce characteristics. The fabric covering preferably consists of a pair of felt fabric panels (14) having a generally dumbbell-like or dogbone-like shape. <IMAGE></p> |
