ATLANTA — Interroll has begun operations at its second plant on the company campus in Hiram, GA. The new building provides 100,000 square feet of manufacturing and warehousing area, as well as 25,000 square feet of offices, plus a kaizen room.

Industry 4.0 is the hottest trend to hit the manufacturing world since the Toyota Production System started to transform assembly lines two decades ago. Although most of the talk about digital production systems and smart factories involves things such as augmented reality, collaborative robots or data analytics, conveyors play an equally important role.

Of all the things that conveyors have moved the past 222 years, none is more iconic than the small chocolate candies that overwhelmed Lucille Ball and Vivian Vance working on the assembly line in September 1952.

This month marks the official celebration of the world’s first moving assembly line. On Oct. 7, 1913, 140 assemblers stationed along a 150-foot chassis line at a Ford Motor Co. plant just north of Detroit stood in place as the work came to them.
