ABSTRACT:
A molded game ball, particularly for volley-ball, hand ball and soccer is made by winding a layer of fibrous material on an inflated rubber bladder, applying a sheet of a rubber mixture with a vulcanizing agent on this layer, imprinting in a cold mold a network of fields on this layer indicating places where cover segments have to be bonded thereon so that do not get in touch one with another on their periphery and by finally pressing this semiproduct with bonded cover segments in a smooth mold at temperatures for vulcanizing.
