Abstract: In order to improve the stability of cigarette's draw resistance and investigate the effects of filling value of cut stem on cigarette draw resistance,the linear regression experiments on the relationship between filling value of cut stem and cigarette draw resistance were carried out.The results showed that:the filling value of cut stem positively correlated with cigarette draw resistance,the obtained linear regression equation was meaningful and in good conformity with actual results,the absolute values of relative deviations of predicted values versus measurements were less than 2%.In practical production,if excluding the effects of moisture content in cigarette,cigarette weight and pressure drop of filter rods,the draw resistance of cigarette could be controlled by the filling values of cut stem via the model.
