The design of a flat belt system consists of a belt running over pulleys, with tension maintained through the use of adjustable idler pulleys. This setup helps to ensure that the belt remains taut, minimizing slippage and wear. The flat belt design features a smooth surface, allowing for efficient transfer of power while reducing friction. Various materials have been employed throughout history, each with specific advantages. For example, leather belts provided durability and flexibility, whereas later advancements introduced synthetic materials, enhancing strength and longevity.
