Abstract

The invention is related to a method for testing multilayer tablets in a multiple rotary press, in which die holes of a circulating die plate are successively filled with tablet material of different layers in consecutive filling devices, and the tablet material is compressed layer after layer to pressed articles having n layers by means of synchronously circulating compression punches in compression stations respectively associated to the filling devices, and the pressed articles are subsequently ejected and unloaded in a unloading station.
