This device comprises plates held against front faces (1a, 2a) of the rolls (1, 2) in order to close the ends of a casting space (3) delimited by the rolls; each front face (1a, 2a) of a roll is equipped with a flexible endless band (5, 5') bearing, on the one hand, on the roll at the junction of its front face (1a) and its cylindrical surface (1b) and, on the other hand, on the opposite face of the associated closing plate (4), in order to ensure the seal between the latter and the front faces of the rolls.
