ABSTRACT:
A pair of non-circular gears having a fixed sum of the radius of the gears is used as transmission gears secured between a power shaft and a crank shaft. Each radius of the non-circular gears increases or decreases according to the required rotation. A powder feeding time in one cycle is prolonged by delaying the lowering velocity of an upper ram near the lowermost dead point of the upper ram which carries out the powder compacting and performing a quick return motion of the upper ram after a compacting zone.
