More Information
Summary:The present 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 succeeding filling devices, and the tablet material is compressed one layer after the foregoing layer into pressed articles having n layers by means of synchronously circulating compression punches, and the pressed articles are subsequently ejected in an unloading station and taken out, in which in a testing procedure, pressed articles with m layers are taken out after the compression in a respective unloading station and are conveyed to a testing station, wherein applies 1<=m<=n, wherein before taking out the pressed articles, at least the m-th layer is compressed more strongly than during the normal manufacture of the multilayer tablets, wherein applies m<n. According to the present invention it is provided that only pressed articles of die holes are supplied to the testing station, which had been completely filled with the tablet material of the m-th layer already before the initiation of the testing procedure.
