Abstract
An apparatus for automatically controlling the work flow of a machine—equipped with effectors ( ) driven by rotational motors ( )—comprises: electronic storage means ( ) having resident functions that relate the angle of rotation described by a controlling motor ( ) with the desired instantaneous position of a controlled effector ( ); means ( ) for detecting the actual instantaneous position of the controlled effector ( ); comparator means ( ) for determining the positional error of the controlled effector ( ) relative to a given expected position upon reaching a certain angle of rotation of the controlling motor ( ); and means ( ) for controlling the motor ( ) of the controlled effector ( ), which receive the error signal from the comparator means ( ) and apply to the motor ( ) a corresponding corrective action designed to control and synchronize the angular position of the controlled motor ( ) with that of the controlling motor ( ).
