The structure of a conveyor belt supportable on throughing rollers for conveying bulk material. The belt is capable of sharp lateral curves and includes a main body section with an embedded, central, inextensible flexible spine formed of cables (12). Corrugations (14), (16) extend outwardly to the edges from the central section of the body. The central section of the body is rectangular in cross section and constitutes the majority of the belt. The belt is molded flat and has layers of cords or strands (20), (22) of inextensible material such as wire, embedded therein from edge to edge. The layers are parallel to each other and to the surfaces of the belt adjacent the edges and adjacent the central portion of the body. Along the lines where the corrugations meet the central portion, the layers are positioned closer together to thereby define hinges (44), (46) for bending of the belt longitudinally to solve the problem of the throughing of the belt during the conveying of bulk material. |
