Influences of preperforated tipping paper gluing factors and design parameters of glue roller on ventilation rate of cigarette

To investigate the influences of preperforated tipping paper gluing factors on the ventilation rate of cigarette, a tipping paper gluing effect evaluation and gluing position adjustment method was developed. With glue-free zone in its right position, the influences of the length and width of glue-free zone and gluing thickness on the ventilation rate were studied via an orthogonal experiment. The results showed that:1) These factors in the order of influence on the ventilation rate were glue-free zone length > glue-free zone width > gluing thickness, wherein the influence of glue-free zone length reached a significance level. 2) With the extension of glue-free zone, the average ventilation rate increased, while the coefficient of variation of ventilation rate decreased. 3) The optimal parameters of glue roller for cigarette brand"Huangshan (B)"were glue-free zone length 22 mm, width 8 mm, and gluing thickness 0.03 mm. The mentioned method provides a technical support for promoting the consistency of ventilation rate of cigarette with preperforated tipping paper.
