ABSTRACT:
An inflatable sports ball has a body with a multiplicity of discrete panels joined together at seams along respective adjacent edges by stitching, preferably machine stitching, to define a volume, and an inflatable bladder disposed within the volume, with a valve extending through an aperture defined in the body outer surface. Each ball panel is formed of a multi-layer laminate consisting of an outer layer of synthetic polymeric material, an intermediate layer of expanded synthetic polymeric material and a woven fabric, and an inner layer of woven fabric. A method for manufacturing an inflatable sports ball using a stitching machine to join pairs of panels at a seam along respective adjacent edges is also described.
