    摘要: A sport ball includes a first casing layer having a plurality of outermost panels. Adjacent ones of the outermost panels abut and are joined directly to one another at a plurality of seams. The first one of the outermost panels has a first internal surface, a first edge adjoining the first internal surface, and a projection extending inward from the first internal surface. A second one of the outermost panels has a second internal surface and a second edge adjoining the second internal surface. The second internal surface abuts and is welded to the projection at an interface. A second reinforcing strip layer is affixed to the first and second internal surfaces with a thermal bond. The second reinforcing strip layer extends across the projection at the interface and joins the first one of the outermost panels to the second one of the outermost panels.
