Many years ago, almost all factories in America had a Lot of
machines/machinery which was driven by big flat belts, usually Leather
belts, I think.In a Lot of situations it was impractible to rig up belt
guards.It was like/similar to that when I worked at Delta Cotton
Oil.Delta Cotton Oil was closed down and torn down a bunch of years
ago.An apartment building complex sits in that area now.
