Wrapped V-belts are characterized by their unique construction, which features multiple layers of fabric and rubber. The “wrapped” aspect refers to the outer fabric cover that encases the belt's core. This design enhances its durability and strength, allowing it to withstand greater loads and resist wear and tear. Wrapped V-belts typically have a trapezoidal cross-section, which enables them to fit snugly into the grooves of pulleys, ensuring effective power transmission.

3. Fabric-reinforced Materials Flat belts may also be constructed from fabric-reinforced materials, typically combining textiles with rubber or polyurethane layers. This reinforcement provides additional strength and flexibility while still allowing for a lightweight design. Fabrics like polyester or cotton are often used, and the choice of fabric can significantly affect the belt's performance characteristics, such as its ability to handle loads and resist wear.
