In 1931 Voit developed and patented the first all-rubber athletic balls, including the process of vulcanization which allowed a material to be fixed onto a separate rubber bladder.
Later in the 1930s, Voit developed the process of icosahedron winding, which allowed balls to be machine wound with nylon threads over the bladder, providing both strength and consistency in shape and permitting mass production by a machine process.
Those Voit patents and products made possible greatly increased athletic and recreation activity in the school systems, and led to universal use of a new type of product that now dominates sales in its field.
Other developments and patents later in the 1950s and '60s included:
