Abstract
A method for forming tablets using a roll press type apparatus for forming powdery material. The apparatus comprises two rolls for compressing tablets, wherein the rolls have a cylindrical shape and are arranged in the same direction, and can rotate toward their inner sides. When only one of the rolls has the plurality of cavities for forming tablets that are disposed on its outer surface, the speeds of their outer surfaces are controlled so that the speed of the roll that has the plurality of cavities on its outer surface is slower than that of the roll that has no cavity. Further, when both rolls have the plurality of cavities forming tablets that are disposed on their outer surfaces, the speeds of their outer surfaces are controlled so that the speeds of the rolls differ. Consequently, tablets that have a high dimensional accuracy and no burrs formed around them can be produced.
