Abstract
A game ball and method for making the ball. The game ball is for use as a conventional, standard baseball or softball having the desired size, rebound and sound when hit. The ball includes a conventional preformed core of cork or the like, and a plastic shell covering the preformed core in lieu of the conventional windings. The conventional leather cover is received over the shell to complete the ball. The shell may be molded of 100% ionomer resin, or ethylene vinyl acetate may be added up to 25% to reduce the rebound, the ionomer resin and EVA being mixed together before molding the shell. The thickness of the shell is at least one-sixteenth inch to provide the desired rebound, and the shell is spherical with a diameter such that the covered ball will have the standard diameter. A liquid anti-bonding agent may cover the preformed core between the core and the shell, the anti-bonding agent being sodium oleate, silicone or urethane.
