Abstract
A transport chain for transporting articles along a guideway includes a plurality of interconnected chain parts. The chain parts are provided with a roll body that allows the transport chain to roll along the guideway. The roll body projects through the underside of the respective chain part to rest upon the guideway. The transport chain can also be provided with accumulating rollers that allow the transport chain to continue moving below the transported articles if the articles should reach a temporary standstill.
