摘要

Device for coating the surface of a metal strip (2) with a metallic coating comprises a channel (6) having a gap with larger dimensions than the width of and the thickness of the strip to be coated; and sealing units (8) for preventing the run-off of the molten coating material (7). The channel is formed as a coating channel through which the metal strip is guided and through which the molten coating material flows. The sealing units comprise units for accelerating the introduction of the coating material into the coating channel. Preferred Features: The sealing units comprise lines which open into the coating channel, and units which displace the coating material within the lines. The lines are flow channels (9a, 9b) arranged within a coating cell (3). The coating cell has a run-off surface for excess coating material.
