Abstract
A substantially improved table soccer/fussball game playing ball is fabricated by molding an oversized spherical blank entirely from a single thermoplastic material, preferably a urethane material having a hardness within the approximate range of from about 50 Shore D to about 60 Shore D. The oversized molded blank is then subjected to a precision surface machining process, preferably using a centerless grinding machine, to reduce its diameter to a desired finished magnitude and to provide the resulting finished playing ball with a very precisely spherical shape. Compared to conventionally fabricated table soccer playing balls, the machined, single thermoplastic material playing ball provides a variety of advantages including a truer playing roll, considerably more durability and resistance to surface wear, and the desirable ability to retain its 'like-new' playing characteristics for a much longer period of time.
