In a coating apparatus, doctor means for effecting a uniform coating of a molten metal includes an air-knife means having a sliding shutter disposed within the nozzle at each end of the slot thereof. Each shutter is configurated and operatively associated with a nozzle wall to form a chamber having an opening at the nozzle slot. Means feed a gaseous fluid through each said chamber at a relatively high pressure to therby effect a composite air-knife having higher pressures at the ends thereof.
