PURPOSE: To improve the producing yield of a metal strip by arranging catching rolls holding with contact of the metal strip between a cooling call and a wind ing roll at the time of producing the metal strip by rapidly cooling molten metal with single roll method.

CONSTITUTION: The molten metal in the crucible 1 is dropped on the cooling roll 3 rotated at high velocity from a nozzle 2 and rapidly cooled to make this the strip S, and the strip S is detached from the cooling roll 3 with gas injection from a nozzle 4 and released to the air. At the time of passing tip part of the metal strip S through between one pair of the opened catching rolls 8, 8, the rolls 8, 8 are closed to hold the tip part of metal strip and swing arm 11 in a catching roll fitting plate 9 is swung from lower part to upper part as centering the winding roll 5, and the metal strip S held with the catching rolls 8, 8 is guided to a disk 6 and coiled onto the coiling roll 5 and the metal strip S continuously come out from the cooling roll 3, is wound onto the roll 5 in wasteless at high yield.
