Abstract: In a continuous metal casting plant which includes a casting wheel which has a peripheral groove, a metal endless band which winds partially about a portion of the circumference of the casting wheel so as to define a casting chamber for receiving molten metal and a crucible which is provided with nozzle for delivering the molten metal, the improvement being that the band is supported and tensioned by a pair of movable structures adapted to slide along a track, each structure having a shoulder and a plurality of rollers. One structure is fixedly secured to the track, and the other structure is movable by means of a piston actuated by sensitizers of the band via charge or load cells. The band is maintained pressed against the casting chamber of the wheel by means of two band presser means disposed on opposite sides of the wheel, each band presser means being mounted on an independently movable carriage which carries a multi-hinge arm and its associated pulley.
