Abstract

A conveyor chain comprising rigid segments which extend over a width of the chain and are configured at least in part as plates of a uniform thickness and density. The segments are connected together in a loop and have elements to couple each segment to a following segment and a preceding segment. Neighboring segments may flex against each other from a substantially straight line to a convex angle in relation to the loop, so that the chain is adapted to conform to rollers or sprockets, but is resistant to flexing in the opposite direction. The segments overlap each other to form a transport area of substantially uniform thickness and density to provide at least one substantially gapless band of substantially uniform transmissivity to radiation in the transport area, wherein the connector elements are located outside the transport area. A system comprising the chain is also provided.
