Abstract

An apparatus has an apparatus body and a support shaft rotatably supported on the apparatus body. An intermediate plate is provided at an intermediate height of the apparatus body with a plurality of dies arranged in a substantially parallel plane where corresponding forming chambers are defined. Relative to those areas corresponding to the forming chambers, upper punches are provided above the intermediate plate in a way to be movable in an up/down direction and lower punches are provided below the intermediate plate in a way to be movable in the up/down direction. The upper punch is held in a raised position in a given timing corresponding to the rotation of the main shaft at which time powder is fed into the forming chamber. When the upper punch is released from being held in a raised position, the upper punch is downwardly driven to allow it to enter into the forming chamber. The lower punch is held in that lowered position where the lower end opening is closed. The lower punch is pushed upwardly in synchronization with the lowering of the upper punch and enters into the forming chamber so that the powder in the forming chamber is compression-formed in cooperation with the upper punch.
