Abstract
A method of optically controlling products consisting, for example, of blanks whereby a succession of blanks fed along a conveyor to a user machine is controlled by an analog sensor for scanning the surface of each blank along a given line, and developing a signal curve as a function of the different graphic characteristics detected along the line; a comparing device compares the signal curve with a reference curve, and emits an error signal in the event the blanks are not the right type and/or are not oriented and/or positioned correctly.
