Ball cover structure of baseball or softball

Abstract

In a structure of a ball cover of a baseball or softball, the ball cover is manufactured from PU material, and the ball cover is one unit from the ball core to the outside of the ball, and a raised sewn section is formed thereon, and the raised sewn section is situated along the mold line on the surface of the ball cover. The PU material is used to replace leather in the manufacture of the ball cover, thereby reducing material costs. Utilizing a mold to directly form the ball cover, and a mechanized production process effectively increases the production rate and reduces worker costs; moreover mechanized production ensures uniformity of the ball, thereby producing balls with precise standards of pressure resistance and bounce values and so on; a ball cover directly formed as one unit and with good overall surface qualities makes it hard for the ball core to be soaked and the sewn section to break, therefore it's extremely waterproof and the outside environment has little effect on the ball, moreover PU material overall displays better durability and resistance qualities than leather, thereby effectively increasing the lifespan of the ball.
