Double sided timing belts

How do double sided timing belts work and where are they used?

Double sided timing belts have teeth on both sides of the belt, allowing them to drive multiple pulleys synchronously.

These belts have a high level of efficiency, thanks to the teeth which grip on to the pulleys to avoid slippage.

Double sided timing belts are commonly found in hand-held power tools, ride-on lawn mowers and vacuum cleaners.
