  • Game ball and method of making same
    Patent number: 4191375
    Abstract: A game ball having an inner bladder and a layer of yarn wound thereabout. The yarn layer is formed by a first strand of synthetic material and a second strand of natural material. As these strands are being simultaneously wound on the inner bladder, an adhesive is applied to the strand of synthetic material. Since the strands contact each other on the bladder, the strands of natural material absorb adhesive from that applied previously to the strands of synthetic material.
