The conveyor belt comprises a bottom consisting of transverse rods and a wire netting, and side plates fixedly connected in pairs with two rods so as to form, together with these rods, a link, which is movable relative to adjoining links about two axes perpendicular to the longitudinal direction of the belt and situated one in the plane of the bottom and the other perpendicular thereto. The wire netting consists of zig-zag wires, each of which encloses not only the two rods of one link but also one adjacent rod of the adjoining link. Furthermore, the ends of each wire are fixed to one of the two rods of the associated link.
