ABSTRACT:
A ball casing in particular for soccer balls is composed of flat cutouts stitched together at their edges, the surface of the ball casing evincing a pattern of one group of equilateral polygonal surfaces and one group of equilateral hexagonal surfaces or three-arm star surfaces, each polygonal surface being enclosed by five hexagonal surfaces or by five three-arm star surfaces.
Several equilateral polygonal surfaces or three-arm star surfaces when seen in planar geometric development form at least one integral planar and preferably stamped cutout.
Each pentagonal surface is formed as a separate and preferably stamped cutout. The individual polygonal surfaces each are stitched at all five edges to the associated edges of the common planar cutout(s) containing the hexagonal surfaces or the star surfaces.
