Abstract
A method for analyzing the filling of a cigarette by using a sinusoidal mathematical model representing the density of tobacco along the longitudinal axis of the cigarette and by conducting experimental measurements of density and of moisture at a plurality of points along this longitudinal axis, calculating a regression determination coefficient from the measured values, calculating the position of the strengthened tip from the phase .phi. and the parameters of the model and from experimentally determined constants, calculating the shift of the strengthened tip relatively to the cut and calculating the strengthening index from the values of these constants.
