| description | A method for test pressing tablets consisting of n layers in a rotary tablet press, the rotor provided with an upper punch and a lower punch (pair of punches) is moved with the pair of punches in a defined filling position, in which the die bore associated with the pair of punches is filled with the material for the first layer of the tablet, wherein the filling cam is moved into a first position, the ejection cam is moved into a lower position, and pressure rollers are moved into a first pressing position by means of associated adjustment drives; then the rotor is rotated by a full revolution and the pair of punches is stopped in the filling position; the filling cam is adjusted to a second filling position, the ejection cam is adjusted to the ejection position and the pressure rollers are adjusted to a second pressing position; thereafter the first die bore containing the first layer is filled with the material for the second layer; and the rotor is rotated by a further full revolution and the pair of punches is stopped again in the filling position, and so forth; at the n-th revolution of the rotor, the lower punch ejects the multi-layer tablet. |
