The poly V belt, often referred to as a multi-ribbed or flat belt, is designed with multiple ribs or grooves running parallel to its length. This configuration allows for a greater surface area to engage with the pulleys, leading to enhanced grip and power transmission. The J section designation refers to the specific profile of the belt, which is tailored to fit a range of applications that require high performance and efficiency. The unique design not only minimizes slipping but also reduces the overall width of the belt, making it ideal for compact spaces.

The mechanism for varying the pulley diameter can take many forms, including adjustable sheaves or conical pulleys. By changing the effective diameter of the pulleys, the system can alter the speed ratio between the input and output. As the diameter of the driving pulley decreases, the speed of the driven pulley increases, and vice versa. This principle allows for smooth transitions in speed and ensures that the system can operate efficiently under varying loads.
