An equipment for the continuous hot dip-coating of a metal strip comprising:
- an annealing furnace;
- a tank containing a liquid metal bath;
- a snout connecting the annealing furnace and the tank, the metal strip running in a protective atmosphere through the snout, a lower part of the snout defining a snout tip and being at least partly immersed in the liquid metal bath in order to define, with a surface of the bath and an inside of the snout, a liquid seal;
- and
- a separate overflow attached to the snout through fixings, the overflow including at least one tray placed where the strip enters the liquid metal bath and is encompassed by the liquid seal.
The equipment as recited in claim 3 wherein the fixings hold means for maintaining a level of liquid metal in the tray.
