A seamless draper belt (32) formed from an elongated flat base structure (36) of fabric and rubber. Transverse cleats (44) having a structural core embedded in rubber are connected to the base structure (36). The elongated base structure (36) and cleats (44) are cured and adhere to one another except for end sections (40, 42) to form a flexible elongated structure, the ends (40, 42) of the base structure (36) being overlapped and cured to form a seamless belt.
