A blind cavity is filled with a predetermined quantity of fine powder from a hopper by bringing the cavity into a position beneath the hopper and causing the predetermined quantity of powder to flow from the hopper into the cavity. The powder is in free flowing agglomerated form and is made to flow from the hopper by subjecting the hopper to vibration, the powder flow being stopped by cessation of vibration when the cavity is filled with the predetermined quantity of powder. An apparatus for carrying out the method is also described. |
