Abstract: The invention relates to a flexible conveyor belt wherein two pairs of links at one end thereof are respectively and rotatably fitted onto each end of transverse rods disposed with regular spacings from each other. One pair of the said links are rotatably connected with a pair of links fitted onto a preceding transverse rod, while the other pair thereof is rotatably connected with a pair of links fitted onto a succeeding transverse rod. These are characterized in that the center of a connecting spindle rotatably connecting the links of the said preceding and succeeding transverse rods is adapted to be located below the center line connecting the centers of the transverse rod receiving holes in the state in which the connected links are rectilineally extended. This enables the flexible conveyor belt to expand, contract and bend systematically with a small curcature radius and smooth and noiseless movement.
