Transport device for a scale, in particular a dynamic scale that preferably operates with electromagnetic force compensation, with a weighing belt that forms a preload for a weighing cell. The weighing belt is constructed to transport materials to be weighed along the X-direction while weighing. The weighing belt receives the materials from a supply device arranged in an upstream inlet area, including a supply belt or supply rollers for supporting the materials and not forming a preload for the weighing cell. Two weighing-guide elements extending in the X-direction and forming a preload provide lateral support of the materials in the Y-direction to weigh the materials during the transport on the weighing belt in the leaning position. The minimum Y-distance between the weighing-guide elements is greater than the maximum extent of the materials in the Y-direction.
