ABSTRACT:
A ball is disclosed formed with a spherical core of polyurethane foam covered with a thin winding of cotton yarn and with a hand stitched outer cover; the ball is formed in a mold by providing a polymeric isocyanate with a mixture of water and a polyol crosslinking catalyst with the ratio between the isocyanate and the mixture of the catalyst and the water being variable to provide a ball of desired resilience and density so that the ball formed by the method can duplicate such characteristics as found in conventional baseballs and softballs.
