| 摘要 |
The invention relates to a carcass (1000) for a ball, in particular a ball for ball games. The carcass (1000) comprises several panels (100) which are connected to each other, wherein each panel (100) comprises at least one preferred strain direction (200, 300), wherein the elasticity modulus of a panel (100) is greater in the preferred strain direction (200, 300) than in other directions. The panels (100) of the carcass (1000) are arranged relative to each other so as to exclude an orientation of a pair of adjacent panels (100) where each panel (100) of this pair has a preferred strain direction (200, 300) which is perpendicular to the connection line (400) between the two adjacent panels (100). |
