ABSTRACT:
A method of and an apparatus for supplying a powdery material to a workpiece to be processed thereby. According to the method, the powdery material is discharged from a hopper and metered, and then fed into a tube extending in the vicinity of the workpiece. Ultrasonic vibrations are imparted to the tube to supply the powdery material to a portion to be processed of the workpiece while the amount of the supplied powdery material is being detected. The apparatus includes a hopper for storing the powdery material, the hopper having an outlet, a tube extending from the outlet to a position adjacent to the workpiece for conveying the powdery material therethrough, and an ultrasonic vibrating device mounted on the tube for imparting ultrasonic vibrations to the tube, and a device mounted on the tube for detecting the amount of the powdery material supplied through the tube.
