PURPOSE: To impart charge generated by frictional electrification to a powder paint by the supply device of powder and a simple device, by which such a problem point as the powder paint cannot be supplied stably due to the clogging of a piping in the course of transferring the powder paint.
CONSTITUTION: The supply device for a powder paint is constituted by arranging a powder paint supply port 11, an air exhaust port 14, a power paint discharging port 20 and an air exhaust port 17 in a vessel 10, and allowing the powder paint supply port 11, the air exhaust port 14, and the air exhaust port 17 to be subjected to piping to a storage vessel for the powder paint, a pressure reducing pump 16, and an air supply source, respectively. Also, this device is formed by allowing a spiral tube 22 to be subjected to piping in the powder paint discharging port 20 of the supply device.
