Abstract
A belt drive for a roller conveyor is provided to assure the firm application of the drive belt to the conveyor rollers regardless of manufacturing tolerances. Each pressing roller has a cylindrical base body as well as at least one belt-pressing disc adjoining it which extends annularly around the circumference of the cylindrical base body and obliquely to the axis of the pressing roller. The belt-pressing disc is arranged, as seen in the direction of the roller conveyor, in connection with the successive pressing rollers, alternately on the right and left of the pressing rollers. By the travel of the belt onto the obliquely developed belt-pressing disc the firm application of the drive belt against the conveyor rollers is assured.
