Flat belts are simple, flat strips made from materials such as rubber, leather, or fabric. They are designed to transfer power between parallel shafts, typically keeping them aligned. One of the most notable advantages of flat belts is their ability to handle large distances between pulleys without significant stretching or slippage. This makes them ideal for applications like conveyor systems, textile machines, and certain types of agricultural equipment.
