摘要 The surface of a basketball is provided with rows of pebbles or projections, each of which has a flat triangular outer surface and three pointed apexes. The triangles in each row are arranged in alternating directions so that the fingers of a player will engage the pointed apexes of some triangles regardless of the direction in which the fingers extend.
