Abstract

An apparatus for singling out tablets for a rotary tablet-compressing press the rotor of which has associated therewith a nozzle which, via a line and a controllable valve disposed in the line, is adapted to be connected to a pressure source in order to route a tablet into a rejects duct wherein the control signals for the valve are produced by a control device, characterized in that the line, between the orifice of the nozzle and the valve, has disposed a pressure sensor which delivers a sensor signal if the valve is opened or a predetermined minimum pressure prevails in the line and a logic evaluation circuit is provided into which the sensor signal and the control signal are input and that an error signal is produced in the evaluation circuit, which signal is evaluated by the control device if the time relation of the control signals and the sensor signals deviates from a predetermined relation.
