ABSTRACT:
The present invention relates to a method and apparatus for charging a high-viscous material in a material tank into a charging tank. The high-viscous material, namely, putty is used preferably as a material for correcting the dynamic unbalance of a rotary body. When the material is charged from the material tank into the charging tank through a nozzle, the pressure of air in the charging tank is reduced and the pressure of air in the material tank is increased to drop the high-viscous material in droplets without taking air thereinto and air which has permeated into the material in the material tank can be removed.
