ABSTRACT:
An improved method of making a fabric covered tennis ball is disclosed wherein a pair of molded semi-hemispheric elastomeric material core halves are joined together by a thermosetting adhesive means, the joining of the core halves taking place in the presence of atmospheric pressure. Heat and pressure are applied externally to the core halves to cure and set the adhesive, and in a preferred embodiment to localize areas, particularly where the adhesive resides between the core halves. An integrally molded air valve is provided in a side wall of one of the core halves to facilitate the introduction of additional air pressure into the core after its having been bonded in assembled condition. A tennis ball fabric covering is provided about and adhesively secured to the core covering the air valve, the fabric being air permeable to allow introduction of additional amounts of air into the completed tennis ball to facilitate production of a desired ball bounce characteristic for the tennis ball.
