Method of fabricating a table soccer of fussball playing game ball

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 without 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 having a sphericity which does not vary by more than about 0.001 inch on any external surface portion thereof. 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.
