Beschreibung
Zusammenfassung:	The invention concerns a method for dip coating a metal strip using a molten metal which consists in causing the metal strip to pass in a volume of said molten metal by causing said strip to circulate in a thin channel wherein the molten metal is introduced at least on either side of said strip and so as to generate a circulating movement of said molten liquid relative to the strip inside said thin channel. The pressure on the two surfaces of the strip inside said thin channel is adjusted independently of each other, and the circulating speed of the molten liquid current relative to the strip is adjusted at a value ranging between 0.5 m/s and 1 m/s.
