Ralph Jacob, who built Akron-based Vulcan Machinery Corp. into a maker of coilers, winders and other downstream extrusion equipment, died March 1 after a long battle with multisystem atrophy, similar to Parkinson's disease. He was 78.
Jacob, an engineer, had a background in tires and helped develop the bias-belted tire. As an employee of Owens Corning, he promoted the idea of glass fibers in tires.
In 1966, Jacob purchased Frank Eddy Machine Co., later renamed Vulcan.
One of Vulcan's early plastics-related products included a high-speed coiler for medical tubing.
Its other products include pullers, cutters, saws and cooling tanks.
In 1998, Jacob passed Vulcan down to his sons, David and Bradley Jacob.
