PURPOSE:To prevent the blur and exudation of a paint, by separating the start of emission from a coating nozzle to a rearward direction from the start end of a groove while starting the suction of a suction nozzle in an upper part before falling the same at the start end of the groove. CONSTITUTION:The emission due to a coating nozzle 3 is started at a position slightly seperated rearwardly from the start end of a groove 2 and the suction due to a suction nozzle 4 is started at an upper position as compared with a usual suction position and, when coating advances until the start end of the groove 2 reaches the intermediate of the inner diameter of the suction nozzle 4, the paint in the groove 2 is sucked toward the non-coated part of the start end of the groove 2. By this method, groove coating is performed well without generating the blur or exudation of a paint.
