Balls comprised of (1) a generally spherically shaped center portion or core prepared from a piece(s) of material, such as a rag or sheet rubber, (2) cohesive tape at least partially covering this center portion, (3) yarn covering the cohesive tape-covered center portion, (4) additional tape (preferably cohesive) substantially completely covering this yarn layer, and (5) a synthetic cloth cover (preferably a double knit polyester). The cover is preferably formed of two figure eight-shaped cloth pieces which have short lines imprinted thereon extending inwardly from the perimeter of each cloth piece such that when the two cloth pieces are joined, corresponding short lines on each cloth piece are aligned such that they either intersect or would intersect if extended thereby simulating the stitching utilized in the construction of conventional baseballs and the like. The balls of this invention have substantially the same size, shape and performance characteristics (particularly the aerodynamic characteristics) of the balls they are meant to replace, i.e., baseballs or softballs, when thrown or hit, but are softer and lighter, allowing for their use in congested areas-they do not travel as far when hit-and by or with young children who are more susceptible to injury with hard balls or handicapped persons who are similarly susceptible to injury and who may have special difficulty with hand-eye coordination. |
