FIELD: tobacco products. ^ SUBSTANCE: flavoured material is applied over paper web continuously fed to the wrapping machine in the cigarette production machine. The machine contains a spreading jet for spraying flavoured material over paper web continuously fed to the wrapping machine; pump for delivering flavoured material to the spreading jet; and pump control device regulating drive speed of the pump depending on operation speed of the wrapping machine. With the help of the pump control device, operation speed of the wrapping machine is divided into many speed ranges and approximated characteristic of the pump are determined in advance. The approximated characteristic appraises correlation between the speed with which the pump is actuated and speed of flavoured material release from the pump in each speed range, the speed with which the pump should be driven depending on operation speed of the wrapping machine according to said approximated characteristic of the pump is determined. As a result, flavoured material is applied over paper web at respective quantity depending on operation speed of the wrapping machine. ^ EFFECT: quality stabilisation of produced cigarettes. ^ 3 cl, 4 dwg, 1 tbl |
