Conveyor belt dating

Belts were often twisted 180 degrees per leg and reversed on the receiving pulley to cause the second shaft to rotate in the opposite direction.

Pulleys were constructed of wood, iron, steel or a combination thereof.

This method is extremely rare today, dating mostly from the 18th century.Flat belts on flat pulleys or drums were the most common method during the 19th and early 20th centuries.The belts were generally tanned leather or cotton duck impregnated with rubber.The other pulleys would supply power to pulleys on each individual machine or to subsequent line shafts.In manufacturing where there were a large number of machines performing the same tasks, the design of the system was fairly regular and repeated.
