Powder mixture is supplied into a die under a state that a center pin is located lower than the top surface of the die, after which the center pin is lifted up to a given molding position where an annular molding space is defined between the center pin and the die. The powder mixture is then compressed from upper and lower sides with an upper plunger and a lower plunger to form a pellet. The center pin and the lower plunger are simultaneously lifted up to remove the pellet out of the die.

Powder compression molding method for producing cathode pellets for dry cells

A method and apparatus for putting small, slender, cylindrical cells in a box in an aligned row. By using the force of a magnet, multiple cells are suspended from the lower side of a conveyor belt, and are aligned and held in this position. By releasing the magnetic force, the cells drop, so that large numbers of cells, in a suspended and aligned state, can be simultaneously put into a cell container waiting below.
