both sides at the ends of each cross beam 10 and secured to the stand parts 8 via consoles 14 limit the movement of the cross beams in a direction away from the strand surface with the help of these adjustable stops the driving rollers can be adjusted in their position relative to the supporting rollers even if any finishing defects or fabrication inaccuracies should be present so that once the cross beams get in touch with the stops the distance between the driving rollers and their counterpart supporting rollers is equal to the distance defined by opposing supporting rollers 2 and 3 the stops are made resilient by means of pressure medium cylinders 15 these pressure medium cylinders 15 are under an adjustable pre stress so that the stops can yield whenever the driving rollers are unduly loaded by the strand while they do not yield when the driving rollers are solely exposed to the ferrostatic pressure of the strand the stop being under prestress yields as soon as the load on the driving rollers caused by the cast strand exceeds the counteracting prestress force of the stop and the adjusting force applied by the adjusting means and acting upon the driving rollers thus the driving rollers are protected from being overloaded it is also possible to employ instead of the pressure medium cylinders 15 springs that are under an adjustable pre stress such as cup springs on one end of each cross beam a hydraulic motor 16 slipped onto each driving roller is supported via a torque support 17 fig6 movement of the cross beams is effected by pressure medium cylinders 18 whose piston rods are each hinged to a wing 12 elongated in the direction toward the pressure medium cylinder the pressure medium cylinders are articulately.
