Abstract
It is an object of the present invention to realize a method and an apparatus for efficiently mass-producing tablets of high mechanical strength, accuracy and quality which are so excellent in solubility and collapsibility that they can be easily taken by persons of advanced ages and infants. By using a turn table and endless belt means to which a number of dies are connected, a part of which turn table contacts with the endless belt means, the turn table and the endless belt means being adapted to relatively move with respect to each other, receptacles are formed by pressing plastic polymer film in mold cavities of the dies. Moist powder supplied from a hopper into filling holes of the turn table is pressurizingly filled in the receptacles by means of a filling and pressurizing device in the region where the turn table is laid above the endless belt means. The surface of this pressurizingly-filled moist powder is leveled by removing the excessive powder when the endless belt means is relatively moved with respect to the turn table, thus forming a tablet. Then, the surface of the moist powder is chamfered, the mass of the moist powder is treated by a dryer, the receptacles are closed by a sealing unit, and they are cut by a predetermined number by a cutting device, thereby finishing tablet products.
