ABSTRACT:
Endless, flexible anti-backbend belts having a molded elastomeric body are disclosed and comprise a plurality of longitudinal high tensile modulus cords embedded in the belt near the inside surface and a layer of substantially incompressible material facing outwardly and forming the outside surface of the belt. When the belt is in a straightened position, the incompressible material provides a resistance to backbending. Other embodiments are also disclosed that operate in combination with drive lugs on the inside surface of a conveyor belt, and the separation of the tensile cords of the conveyor and anti-backbend belts provide a resistance to backbending such as to support the conveyor in the area between its drive and take-up pulleys.
