1. A method to set up at least one movable operating member (5, 7) of an automatic machine (1) for manufacturing consumer articles (3); the method comprises the steps (16, 17) of:
defining a first motion profile (FP) of the movable operating member (5, 7), through which at least one processing of the articles (3) is to be performed; and
defining a corresponding second motion profile (SP) of an electric actuator system (8, 9), which, through a motion transmission system (12), is mechanically connected to the movable operating member (5, 7) and moves the movable operating member (5, 7) with the first motion profile (FP);
determining possible imperfections in the processing of the articles (3) caused by the movable operating member (5, 7);
correcting, by means of an interface device (15) of the automatic machine (1) and based on the possible imperfections in the processing of the articles (3), the first motion profile (FP), thus obtaining a first changed profile (MFP) of the movable operating member (5, 7);
calculating, through a control unit (14), a reverse kinematics of the first changed profile (MFP) of the movable operating member (5, 7) through the motion transmission system (12) so as to obtain a second changed second profile (MSP) to be commanded to the electric actuator system (8, 9); and
identifying one or more knots (K) of the first motion profile (FP); said knots (K) being changeable by means of the interface device (15).
