Abstract
A method of regulating the counterpressure in an apparatus for plasticising and quantitatively regulating plastic material by means of a screw which is driven by separate servo motors for the rotary movement and the axial movement, wherein the deviation of the counterpressure from the reference value is detected by at least one sensor, the axial movement of the screw being predetermined and deviations of the pressure from the reference value being compensated by altering the rotary movement of the screw.
