ABSTRACT A stitchless fabric covered ball having a uniform surface free of adhesive seams or other irregu- larities is disclosed. The ball has a hollow spherical core made from an elastomeric material, and a plurality of fabric panels 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 to form a substantially continuous fabric covering uninterrupted by adhesive seams. The ball has uniform radial symmetry which provides for more predictable and uniform aerody- namic and bounce characteristics. The fabric covering preferably consists of a pair of felt fabric panels having a generally dumbbell-like or dogbone-like shape. The invention is particularly well suited for, though not limited to, tennis balls. The invention also relates to a process for making a stitchless fabric covered ball having a uniform structure which is free of adhesive seams.
