PURPOSE: To enhance coating deposition efficiency in the state regulated to follow up a line speed while preventing the scattering of a powder and granular material to the surroundings and the roughening of a coating layer surface at the time of applying the powder and granular material.

CONSTITUTION: The powder and granular material Pd is tentatively applied on a part of a circulation type moving body 1. The speed difference between the moving speed of the circulation type moving body 1 and the moving speed of a traveling and incoming object O1 to be coated is set at 0±5m/min. The A compressed gas is blown or mechanical vibrations are applied to the circulation type moving body 1 from its rear side to apply the tentatively applied powder and granular material Pd to the object O1 to be coated.
