Through the effect of the cylindrical pressure roller (4) on the die (1), the cover lines (10) of the cylindrical pressure roller running through the momentary contact points between the head surface (2) of the die (1) and the cylindrical pressure roller (4) are formed by means of a tool as successive contact line shares. The contact line shares are inclined to the side of the die directed to the rotary central point (7) of the circular press by a few hundredths of a millimetre.
