PURPOSE: To make it possible to intermittently, rapidly, continuously and correctly supply workpieces by immovably bringing the belt sides of two transporting belts into contact with the workpieces transported by these belts on both sides and forming at least one belt of a toothed belt.

CONSTITUTION: The horizontal belt sides on the lower side of the endless toothless belt 12 on an upper side are guided along an upper guide plane 18 coinciding with the belt width in horizontal guide devices 14 on the upper side having a perpendicular guide plane 16 on the side lower by the size from the bottom to the rear surface of the belt. The belt sides of the toothed belt 12 are arranged at one end of the guide devices 14 and are turned up by plural toothed disks or smoothly constituted disks. The second lower endless toothed belt 28 is guided on a toothed surface facing up in guide devices 30. The endless toothed belts 12 and 28 may be separately and intermittently driven by controllable servo motors of a stepwise feeder.
