Abstract: A dosing disc capsule machine has a tamping pin carried in a mounting block for extending into openings in a dosing disc to compact powder in the openings to form a plug. The plug is then transferred into a capsule body by an ejection pin. In accordance with the invention, a load cell is positioned above the tamping pin in the mounting block for measuring the compressive force exerted on the powder by the tamping pin. The load cell occupies the space normally occupied by the overload spring in such dosing disc capsule machines. Thus, modification of the tamping pin is not necessary, and the simple substitution of parts makes it possible to interchange the instrumentation from one machine to another. Further, the modifications are minor and do not affect the normal operation of the machine.
