  • Charging cavities
    Patent number: 5641009
    Abstract: A cavity is charged with particulate material by positioning a predetermined quantity of the material in a box (140). The box has substantially the same horizontal cross-sectional shape as the cavity and is closed at the bottom by at least one door (78) on which the material rests. In order to level the material, the box (140) is moved to and fro horizontally a plurality of times with the energy imparted to the material being progressively reduced during the movements. The door (78) is then opened sufficiently rapidly that the particulate material falls out of the box (140) into the cavity substantially as a unit.
