Effects of Cutting Mode on Cut Tobacco Structure and Cigarette Manufacturing Quality

For optimizing strips cutting and improving the consistence of physical quality of cigarette, the results of traditional cutting and fixed-length cutting were investigated in terms of cut tobacco structure, cigarette's manufacturing quality and tobacco consumption. The results showed that:comparing with traditional cutting, 1)40 mm fixed-length cutting decreased the proportion of long strands(> 3.35 mm in length)and increased the proportion of cut tobacco < 3.35 mm in length, and the proportion between long strands and middle-short strands was improved; 2) fixed-length cutting significantly increased the stability of physical quality of cigarette, the rate of cigarette not up to the standard weight decreased from 5.2% to 2.2%, the standard deviation of individual cigarette weight reduced by more than 12%, and the standard deviations of draw resistance and hardness of cigarette also reduced to a certain degree;3)the cut tobacco consumption per 50000 cigarettes decreased, but the strips consumption per 50000 cigarettes increased.
