Patent ID: 7228959

Claim:
A modular conveyor belt capable of radius travel and made up of a multiplicity of assembled plastic belt modules in module rows, the belt being connected together from row to row by connecting pins extending along hinge lines, the pins passing through apertures in link ends of the modules extending in the forward direction of travel and in the aft direction, the link ends of adjacent module rows being interdigited, and comprising: the link ends extending from the modules in both fore and aft directions having slots at said apertures, to receive the connecting pins, in each module, the link ends comprising a forward set and an aft set of link ends, one set being at a high level and the other set at a low level, and the modules being assembled and interdigited such that high link ends of one module row connect with high link ends of an adjacent module row, and low link ends of the one module row connect with low link ends of another adjacent module row, whereby on collapse of modules together at the inner side of a curve in radius travel of the conveyor belt, high link ends that extend in a first direction fore or aft pass over and overlap low link ends of an adjacent module also extending in the first direction in a next adjacent module row, and such high link ends ride over a connecting pin in the next adjacent module row, providing for tight collapse of the belt at the inner edge on a curve.
