The toothed belt drive includes a drive roller having a toothing system which runs along an outer circumference, a conveyor belt which is driven by the drive roller in a circulating direction, and a support roller. The conveyor belt includes a toothing system along an inner side and a continuous groove in the toothing system parallel to the circulating direction. The support roller includes a support disk which projects radially as an elevation so as to bear in a force-loading manner against the inner side of the conveyor belt. The elevation is a counterpart to the continuous groove of the conveyor belt. The support disk is arranged so that the elevation lies on a bottom of the continuous groove. ## Claims ### Claim 1 A toothed belt drive for transport in at least one of a production process and a packaging process, the toothed belt drive comprising: at least one drive roller comprising a toothing system which runs along an outer circumference of the at least one drive roller;
