Abstract: An object, such as a soccer ball, is provided with perforated, interior panels disposed between an interior inflatable bladder and an outer covering which is stitched together from a plurality of individual panels. The stitching process produces raised portions surrounding the interior sides of the outer covering. These raised portions define recesses into which the perforated interior panels are disposed. The recess-filling panels overlie the ridges which are hard and whose hardness is counteracted by these preferably perforated panels. This provides a smooth surface against which the inflatable bladder rests. Additional flexure is also provided by perforating one or more of the layers in the outer covering.

Abstract: A ball includes a core and a surface cover that is formed by sewing together two shape-mated covering pieces. Each covering piece has a close-to-edge area defining inboards an inward circumferential zone in which spaced through apertures are defined.

Abstract: In a method of manufacturing wear-resistant panel of ball, a TPU film having a pattern printed on a reverse side thereof is positioned in a mold for suction molding and trimming to form a panel of ball, which is then positioned in another mold for bonding to an injection molded TPU foam, and the bonded TPU film and TPU foam are allowed to cool to complete a three-dimensional panel of ball. Panels of ball so manufactured are then sewed together to form a ball. The TPU film protects the pattern behind it against abrasion and wear, so that the pattern is always fresh and complete to give the ball a distinguishable appearance. The injection molded TPU foam layer gives the panel of ball a high stability in shape to prevent surface folds. The whole process is simplified to reduce the manufacturing cost.

Abstract: A spherical ball, for projection through the air to deviate from an expected trajectory, has a first hemisphere (12) and a second hemisphere (14). The surfaces (52, 54) of the first hemisphere (12) and the second hemisphere (14) are generally smooth, except for the provision of a simulated seam (53) which gives the ball the appearance of a baseball. An insert (40) of felt-like material is provided in the second hemisphere (14) with the surface of the insert (40) flush with the surface (54) of the hemisphere (14). When the ball is projected along the plane of the line (16) between the hemispheres (12, 14), it will deviate from that plane in the direction of the first hemisphere (12). The ball is manufactured by locating the insert (40) in a mould (60) and injecting polyurethane foam (64) into the mould (60) with the insert (40) bonding with the foam, (64).
