Abstract

Chain conveyor for workpieces and workpiece carriers with a roller chain (18) which includes a roller (28) at every second link joint. Spring elements (36), which cover the free spaces between the rollers (28) towards the top, are caught on hinge pins (24) lying between the rollers (28). Chips, screws or the like small parts are thereby prevented from reaching the free spaces between the rollers (28) and damaging the support surfaces of stopped workpieces or workpiece carriers.
