Metal strip is coated with a coating material containing a volatilizable solvent and is heated in an enclosure for vaporizing the solvent. Condensation of vapors on the metal strip within the enclosure is avoided by providing an exhaust of sufficient capacity to withdraw all of the heated and vaporized solvent, after which it is burned, mixed with a gas having a temperature lower than its temperature, and returned into the enclosure and applied against the surface of the metal strip.
