Abstract

A balanced bladder for inflatable balls having the characteristics to follow the desired trajectory along with the property to rebounce along the path of forward motion. The subject bladder comprises a shell and a valve fitted at the open end of the said shell. The said shell comprises at least a layer or at least a pair of layers of compounded synthetic latex and/or compounded natural rubber latex and a partial additional layer of synthetic latex and/or natural rubber latex provided diametrically opposite to the open end of the said shell characterized in that the said partial additional layer is superimposed on 2-20 % of the circumference of the said shell, having the weight conforming to the weight of the said valve. The invention also resides in the process for the preparation of the balanced bladder wherein the shell comprising at least a layer of compounded natural rubber latex and/or compounded synthetic latex and a partial additional layer of compounded natural rubber latex and/or compounded synthetic latex each is prepared by dipping the former in not only compounded natural rubber latex bath but also in the compounded synthetic latex bath. In an another embodiment, the process comprises dipping the former in the bath comprising blended compounded natural rubber latex and compounded synthetic latex. Finally, a valve is fixed at the open end of the resultant shell to obtain a balanced bladder.
