Abstract
A method for corrective action on the operation of a line for the production of absorbent sanitary articles, comprises capturing at least one image of each article being fed out of the line; using the image to define first parameters indicating the positioning and/or assembly and/or shape of at least one respective component; detecting a production defect if at least one of the first parameters is outside a respective acceptability range; identifying second, line operating parameters which are used to indicate if the first parameter is outside the respective acceptability range; comparing the line operating parameters with respective third, reference parameters indicating optimum line operation; using the comparison to derive a map of abnormal operating parameters; checking if each combination of abnormal operating parameters indicates a respective cause of malfunction of the line; defining a respective corrective action.
