Abstract
A modular plastic belt which can be constructed to have any length or width, and which can flex horizontally in any direction is disclosed. In the preferred embodiment, each of the modules forming the belt includes a multiplicity of elongated links extending between first and second pluralities of link ends. At least one of the link ends on each elongated link defines an elongated pivot aperture, and in the preferred embodiment both apertures on each link are elongated. The elongated links are joined together by a pair of transverse connecting structures integrally formed with the bottom and top surfaces of the elongated links. The pair of transverse connecting structures are located such that the end-most portion of a link end of a first module pivotally connected to the first pluralities of link ends of a second module can simultaneously move past the end-most portion of a link end of a third module pivotally connected to the second plurality of link ends of the second module.
