Abstract: An object, such as a soccer ball or a handball, 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. With particular reference to handball manufacture the interior panels comprise two layers, the outer one of which contains recesses containing shock absorbing gel type material.

Abstract: A method for manufacturing a sports ball comprises cutting outer panels and inner padding cut-outs from three different sheet materials. The internal padding layer materials have perforations and are geometrically similar in shape, but smaller than the outer panel cut-outs. A layer of heat-reactive adhesive that expands upon heating is applied in the machine-stitched seam areas before the panels are stitched together. The padding layer is glued to the inside-out ball cover before the cover is turned right-side out. A reinforced bladder is inserted into the cover. The remaining seams are stitched shut utilizing one of various different methods, and then the ball is molded in a heat and pressure mold that causes the seams to be welded as well as stitched, due to the expansion of the heat-reactive adhesive to cover the stitching in the seams. Enhanced performance characteristics of the resulting ball arise from the air spring aspects provided by the combined features.

Abstract: In the process of making a hollow product, especially a deformable toy ball, two halves made from an elastomeric material, a thermoplastic material, rubber, a blend of rubbers, or a thermoplastic elastomer are formed by injection molding with mating edges that engage with each other when the halves are assembled to form the product. The edge of one of the two halves is advantageously formed with a recess centered in the edge, in which a flange formed on the edge of the other of the two halves engages to provide a form-fitting connection between the two halves. The opposing edges are then bonded with each other by fusion or melting or by an adhesive applied to at least one of the edges prior to assembling the halves together. A deformable ball produced by the process is also described.
