Abstract

A controller of a rotary compression-molding machine is configured to rotate a turret including a table including a die bore, and punch retaining portions vertically slidably retaining punches disposed above and below the die bore along with the punches, and to fill the die bore with a powdery material from a filling device disposed just above the table, to compress the powdery material filled in the die bore with the punches and to obtain a molded product. The controller is configured to adjust rotational speed of the turret and the punches to allow the powdery material in a feed pipe, directly connected with the filling device and configured to feed the filling device with the powdery material, to have a level of an upper surface kept within a constant target range.
