Claim:
A ball, comprising: a ball core having a substantially spherical outer surface; and at least two carcass panels, each of which is cut into a predetermined shape, having a main portion, and an edge portion formed along a peripheral edge of said main portion, wherein each of said carcass panels is attached on said outer surface of said ball core without stitching with other said carcass panels at a position that said carcass panels are attached in an edge-to-edge manner, such that said carcass panels form an outer shell at said ball core in a thread-less manner, wherein said side edge portion of each of said carcass panels is slanted with respect to said main portion so that a top surface of said side edge portion downwardly and inclinedly extends from said main portion to said outermost edge of said corresponding carcass panel, such that when said carcass panels are attached edge-to-edge, said side edge portions of said adjacent carcass panels form an indented channel on said outer shell, wherein each of said carcass panels further comprises a friction arrangement formed along said side edge portion thereof to provide a zone of frictional surface for a player gripping and throwing said ball with a particular trajectory, wherein said friction arrangement comprises a plurality of elongated indentions spacedly formed along said side edge portion of said corresponding carcass panel for providing a non-smooth outer surface of said corresponding carcass panel.
