Abstract

The invention concerns a method and device for producing flat blanks, in particular tablets, from a product mass containing an active substance by fusion calendering. To this end, a charging device delivers the product mass to at least one pair of rollers consisting of two calender rollers which can rotate in opposite senses. The device comprises a circulating moulding strip which is guided between the two rollers and comprises on its surface recesses for receiving the product mass.
