An inflatable sports ball is provided. The inflatable sports ball having a bladder defining an exterior bladder surface and a bladder circumference. The inflatable sports ball may further comprise a cover disposed about the bladder, the cover comprising an outer cover layer and an intermediate structure. The intermediate structure is disposed between the outer cover layer and the bladder. The intermediate structure comprises a restriction structure. The restriction structure may comprise a plurality of overlapping strips. Each of the overlapping strips is interwoven with each of the other strips and wrapped about the bladder circumference. In this way, the restriction structure comprises a uniform number of radially-stacked layers of the overlapping strips over a substantial entirety of the exterior bladder surface between the exterior bladder surface and the outer cover layer.

The present disclosure is relates to a TPU ball structure and a manufacturing method thereof. The TPU ball structure includes a ball bladder layer, a yarn layer and a surface layer. The ball bladder layer is made of TPU material. The yarn layer is made of TPU material, and the yarn layer is disposed to cover the ball bladder layer. The surface layer is made of TPU material, and the surface layer is disposed to cover the yarn layer. The above layers of the TPU ball structure are made of TPU material to satisfy a requirement for environmental protection, and are recyclable. There is no need to use adhesive to adhere the above layers of the TPU ball structure. Therefore, the peeling strength between the layers of the TPU ball structure can be increased so that the whole peeling strength of the TPU ball structure can be increased.

An American-style football may include a prolate spheroidal shaped bladder having a longitudinal axis, an outermost layer about the bladder, a lacing surface featuring a series of parallel projections from an exterior of the outermost layer and an intermediate sandwiched between the bladder and the outermost layer, wherein the intermediate layer is configured to decrease a MOI of the football.

An inflatable sports ball having a bladder and a cover disposed about the bladder in provided. The cover may have an exterior surface that defines a plurality of plateau sections, a first plurality of indentations, and a second plurality of indentations that cooperate to define a topographical arrangement across the exterior surface. Each of the first plurality of indentations has a first indentation depth, a first indentation width, and a first maximum aspect ratio. The first maximum aspect ratio is defined as the ratio of the first indentation width to the first indentation depth. The second plurality of indentations has a second indentation depth, a second indentation width, and a second maximum aspect ratio. The second maximum aspect ratio is defined as the ratio of the second indentation width to the second indentation depth. The second maximum aspect ratio is greater than the first maximum aspect ratio.

A sports ball is provided and may include an interior bladder and a cover disposed about the interior bladder. The cover may comprise a plurality of adjoining panels. The cover may further define an exterior surface comprising a plurality of plateau sections and a plurality of indentations extending radially inward from the exterior surface. The plurality of indentations may include a plurality of peripheral channels or seams and a plurality of interior channels. Each seam has a seam length and the plurality of seams has a first aggregate deboss length. Each interior channel has a channel length and the plurality of interior channels has a second aggregate deboss length. Collectively, the seams and interior channels have an aggregate feature length, which is defined as a sum of the first aggregate deboss length and the second aggregate deboss length. The aggregate feature length is greater than 800 centimeters.
