Abstract

For transporting a train (15) of flaskless molds using a simply designed system along a storing, teeming and cooling run or part of a conveyor in a foundry so that the castings are made highly true to size, the forces needed for speeding up and slowing down the mold train (15) are caused to take effect at a desired level on the mold train (15) and, together with the forces acting oppositely to the thermal expansion of the molds (7) within the mold train (15), the forces are transmitted to the full length of the mold train only by the molds (7) themselves.
