13. The sports ball of claim 12 wherein four radiating arms extending from each pentagon outline are generally linear and equidistant in length.
14. The sports ball of claim 1 wherein said first and second paneled sheets are molded in a molding apparatus.
15. The sports ball of claim 14 wherein said first and second cover panels blanks are cut from said first and second paneled sheets, respectively.
16. The sports ball of claim 1 wherein said first hemispherical cover portion is bonded to said second hemispherical cover portion along overlapping sections between said cover portions.
17. The sports ball of claim 16 wherein said first hemispherical cover portion is heat bonded to said second hemispherical cover portion along said overlapping sections.
18. A sports ball comprising:
a first cover portion comprising a first cover panel blank bonded to a first reinforcement material blank, wherein said first cover panel blank is formed from a first continuous sheet of cover material comprising a plurality of panels, wherein said first continuous sheet of cover material is seamless such that each of said panels is integrally connected to adjacent panels of said sheet, and wherein said first reinforcement material blank comprises a plurality of linked polygon outlines;
a second cover portion comprising a second cover panel blank bonded to a second reinforcement material blank, wherein said second cover panel blank is formed from a second continuous sheet of cover material comprising a plurality of panels, wherein said second continuous sheet of cover material is seamless such that each of said panels is integrally connected to adjacent panels of said sheet, and wherein said second reinforcement material blank comprises a plurality of linked polygon outlines; and
wherein said first cover portion is bonded to said second cover portion to form said sports ball.
