Conventional conveyor belts are comprised of three layers. There’s the top layer, or cover, which is what the product rests on during transportation. The middle layer is also known as the carcass, which helps support the belt. The carcass tends to be made of either metal or woven fabric. Then, there’s the bottom cover to complete the belt
