Abstract
Single cigarettes selected as samples at the outfeed stage of a manufacturing line undergo a systematic quality control operation, performed by a testing unit, that consists in verifying a given number of characteristics for each cigarette and generating a set of signals each reflecting the quality of a respective characteristic; the succession of signals, each assigned a value on a predetermined scale, is represented in the form of a graph. Once a significant sample has been processed, the values assigned to all the characteristics of the tested cigarettes are displayed in a table, ordered such that each column will serve effectively as a production report on an individual cigarette.
