  • Patent number: 6343715
    Abstract: A filling apparatus for axial powder presses with a filling device includes a filler drive plate, a filling shoe arranged in particular on the side of the press, and a powder feeding device. The filling device can be moved forward and backward on a filler plate by means of an actuator, and in a filling position the filling shoe can be pressed against the filler plate respectively against a die surface embedded therein. According to the invention, the filling shoe is only loosely coupled to the filler drive plate, thus allowing the filling shoe to be subjected to a controlled and uniform adjusting force.
