Abstract
A seamless draper belt formed from an elongated flat base structure of fabric and rubber. Transverse cleats having a structural core embedded in rubber are connected to the base. The elongated base structure and cleats are cured and adhere to one another except for end sections to form a flexible elongated structure, the ends of the base structure being overlapped and cured to form a seamless belt. An elongated guide is integrally formed on the base structure face opposite the face containing the cleats.
