Compression-molding machine

A feeder applied to a rotary compression-molding machine comprising a turret including a die table having die bores penetrating therethrough, a feeder positioned adjacent the die table, an upper punch and a lower punch slidably retained above and below each of the die bores, respectively, and an upper roll and a lower roll provided adjacent the upper punch and the lower punch, respectively, the compression-molding machine being configured such that the turret is horizontally rotated to fill the die bores with a powdery material from the feeder when the die bores pass below the feeder, and the powdery material filled in the die bores is compressed when a pair of the upper punch and the lower punch passes between the upper roll and the lower roll, respectively, to mold and produce a molded product, the feeder comprising:

• a housing holding the powdery material to be filled in the die bores and including, in a bottom plate facing an upper surface of the die table, a through-window through which the powdery material spread in a rotation direction of moving the die bores is dropped;
• a sealant protruding downward from a lower surface of the bottom plate and extending in the rotation direction at a position shifted inward and outward from the through-window along a radial direction orthogonal to the rotation direction on the lower surface of the bottom plate;
• and
• a leveling plate positioned at a position in a vicinity of a terminal end of the through-window along the rotation direction on the lower surface of the bottom plate, protruding downward from the lower surface of the bottom plate, extending in the radial direction, and supporting a terminal end portion of the sealant between the leveling plate and the bottom plate.
