发明名称 Toss ball construction
摘要 A ball adapted to cling to a textile surface as an incident of being tossed thereagainst. The ball includes a lightweight spherical body having affixed to the external surface thereof a sheet of flexible Velcro fabric. The sheet is provided with a plurality of slits defining therebetween longitudinal strips. Prior to affixation to the spherical body surface, the sheet may have a generally rectangular configuration, with the slits extending parallel to each other and terminating in spaced adjacency to the opposite ends of the sheet. When formed about the spherical body, the slits are spread to have a maximum width about a circumferential portion of the spherical body. The strips are joined at one end by a first end wall extending polygonally about one portion of the spherical body and at the opposite end by a second end wall extending similarly polygonally about a diametrically opposite portion of the spherical body. The end walls may be turned from the strips to extend outwardly from the surface of the spherical body.
