One of the industrial belts made of polymer material is the round or poly corded belt, which has a circular cross-section. Belts are used as power transmission belts to transfer power between two or more pulleys, and they are often used in several rows on industrial conveyors. The round belt is produced in various diameters, often up to a maximum diameter of 3/8 inches, and is also used in the form of o-rings in closed rings. Polycord belt تسمه بن گرد is produced in different colors, but in green, black, blue and sometimes red, it has the maximum use in industries.
The round belt has very high flexibility and due to its circular profile, it has no angular sensitivity in bending. This factor is one of the main reasons for the use of the round belt as a conveyor belt in many industries, because unlike the flat conveyor belts, which only have the ability to rotate if they are cut in the shape of airport belts, the round belt has an angular limitation in flexibility. And it does not twist. Therefore, in cases where the size and dimensions of the load are suitable for carrying and it does not fall from the distance between the parallel rows of round bins on the conveyor, these belts are used in many cases.
