Abstract
The invention relates to a rotary tablet press comprising: a rotatingly drivable rotor, having a die plate comprising die holes and assigned to the die holes upper and lower punches, rotating synchronously with the die plate, whose axial movement is controlled by upper and lower control cams, having at least one filling station comprising at least one filling device for filling the die holes with material to be pressed, having at least one compression station disposed downstream of the filling station in the rotational direction of the rotor, comprising at least one pressing device which presses the upper and/or lower punches into the die holes when passing through the compression station in order to press the filled material in the die holes, and having at least one ejector station, disposed downstream of the compression station in the rotational direction of the rotor, comprising an ejector device for ejecting the pressed tablets in the die holes, characterized in that at least one vibration generator is provided in the circumferential direction of the upper and lower punches between the filling station and the ejector station that at least temporarily vibrates the upper and/or l…
