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.
