A spiral link belt comprising a multiplicity of synthetic resin helices consisting of flat winding lets and winding arcs with the winding arcs of a helix meshing in zipper fashion with the winding arcs of the adjacent helix. Pintle wires are inserted into the channels formed by the meshing winding arcs of each two helices. A plurality of helices consist of at least two components, the first component being disposed on the inside of the helix and the second component being disposed on the outside of the helix. Preferably, the second component which is disposed on the outside of the helix, is embedded in a groove in the first component.
