ABSTRACT:
A method is provided for rapidly distributing mixed gases throughout a partially evacuated ball mold. The invention is particularly useful in the pressurizing of tennis ball centers with a mixture of air and a low permeability gas. By this invention, the distribution of the low permeability gas throughout the mold can be accomplished by first partially evacuating air from the mold then injecting the mixed gases into the mold.
