A conveyer belt for moving along a path curved in its own plane has its supporting surface provided with portions which form transverse folds and are of a material yieldable with regard to deformation stresses, said supporting surface resting on transverse axles, rods or plates which are connected by a continous flexible pulling means, e.g. a chain, and provided at their ends with rollers for running on supporting tracks. As shown, Fig. 1, the belt consists of stiff or reinforced portions 1, e.g. having canvas inserts, connected by U- shaped parts 2 which are readily flexible and which rest on axles 3 provided at their ends with horizontal and vertical rollers 4, 6, running on angle irons 5, Fig. 3. The belt is driven by an endless central chain 8 suspended from the axles by hooks 7, and driven by two pulleys 9, 10 driven together. Instead of resting on the axles, each part 2 may be in two halves 15, Fig. 6, one to each adjacent end of a portion 14 of reinforced belt, the halves being bolted to the axles 16. In a modification each end of a portion 14 has both an upwardly and a downwardly extneding half U part 15 the top and bottom pairs of halves of adjacent portions 14 being bolted to a vertical plate taking the place of the axle 16. In a further modification the U- shaped parts may be replaced by tubular flexible members. which may be formed integrally with the belt portions with the latter lying on the diametral plane of the tubular members. In a further form, Fig. 10, the belt may consist of sections connected together on axles 36 by bolts 35, each section having a number of the U-shaped parts 2 between which are the stiff parts. The belt is preferably troughed as indicated by the depth of the trough 32. Stiffening members 30 which have beadings 33 and downturned edges 34 perform the dual purpose of troughing the belt and stiffening the belt between the parts 2.
