Abstract: A method of manufacturing tablets in a press having a rotary die plate cooperating with a filling device including a rotary filling wheel and a rotary dosing wheel arranged on top of the die plate, and a plurality of die plungers each projecting into an assigned die in the plate, and further including means for adjusting the vertical position of the plunger; the method comprising the steps of adjusting the rotational speeds of the filling and dosing wheels to a value at which minimum variations of compressing forces take place, comparing a predetermined range of variations of the compressing forces with the measured actual values and adjusting the weight of the tablets in process by readjusting the vertical position of the plunger in response to the ascertained difference, and thereafter readjusting the rotational speeds of the wheels to minimize the variations of the readjusted compressing forces.

Abstract: In a tablet press which includes a rotary disc provided with a plurality of dies and pistons engaging from below the dies, a filling wheel and a metering wheel arranged for a simultaneous rotation on the upper surface of the disc in the range of the dies, a vertically adjustable cam track on which the pistons ride, an electronic device for measuring pressing forces in the dies and control means for generating control impulses in response to the range of variations of the consecutive pressing forces, a method of producing uniform tablets by adjusting the rotary speed of the wheels according to the control pulses to minimize the variations of the pressing forces and subsequently adjusting the vertical position of the cam track and thus the weight of the tablets according to additional control pulses generated by comparing the average value of the measured compressing forces with a predetermined desired value.
