<p>The invention disclosed and claimed here is a padded inflatable game ball (10). The ball (10) is a seamed ball consisting of a spherical rubber bladder (12), a layer of winding (14) surrounding the bladder (12), a cellular sponge layer (16) surrounding the winding (14), and seams (20) and external skin panel sections (28, 30) surrounding the cellular sponge layer (16). The sponge layer (16) provides padding under the skin panel sections (28, 30). The seams (20) are made of narrow strips of high density rubber which cover a relatively small section of the overall surface area of the sponge layer (16). This allows outgassing of the sponge layer (16) as it is foamed during the ball manufacturing process.</p> |
