摘要： A device for adjusting a doctor blade of a printing machine comprising an inking roller facing the doctor blade and adapted to be spaced therefrom by a gap to establish a predetermined ink thickness on the inking roller. Sensors are coupled to the doctor blade for determining the spacing between the inking roller and the doctor blade. Servomotors are coupled to the doctor blade to adjust the position of the doctor blade thereby to adjust the size of the gap. A microcomputer receives signals from the sensors to compare signals from the sensors with the desired gap according to given values of ink thickness and for sending signals to the servomotors to adjust the doctor blade so that the actual distance and the desired distance correspond. The microcomputer also receives the signals from the sensors in non-adjusted state when the inking roller is in contact with the doctor blade to establish this as the zero position of the doctor blade. The zero position can be detected automatically before each resetting of the doctor blade or it can be detected at periodic intervals or by external instruction.
