ABSTRACT:
The coating device comprises a furnace (1) comprising a crucible (4) and a lateral distribution conduit (3) whose outlet communicates with an externally open release aperture (2) serving to distribute the molten metal over the entire width of the metal strip (6) to be coated. This strip (6) is entrained from a supply spool (7) to a storage spool (8) and passes over a positioning roll (10) mounted opposite to the release aperture (2), the spacing between this roll and the edge of the release aperture being adjustable by means of a screw (15). A bank of burners (16) is located opposite to the reverse of the strip (6) and upstream of the release aperture (2) in order to heat the strip before it passes in front of the release aperture (2). A molten metal bath is thus constantly maintained between this release aperture (2) and the face to be coated of the strip (6) which is covered with a layer of metal during its displacement.
