The toothing (6) of the racks (5) are provided on sides of the racks (5) facing towards or away from each other, the line of action of the resulting tangential components (Ft) of the tooth forces (F) coincides with the draw axis (11) and the torques caused by the radial components (Fr) of the tooth forces (F) in the region of the two racks (5) and acting on the draw carriage (3) in opposite directions cancel each other out.
