One of the oldest forms of power transmission, flat belts are well suited for high-speed, samll-pulley drives.Flat Belt Early drives used flat belts running on flat-faced wheels. A typical industrial plant powered multiple machines with flat-belt drives running from overhead line shafts, via speed-reduction stages where required.
