Claim:
A cigarette making apparatus comprising a wrapping machine for continuously wrapping shredded tobacco in a wrapping-paper web by bending both sides of the wrapping-paper web; a wrapping-paper web feed section for continuously supplying the wrapping-paper web to the wrapping machine at speed depending on operating speed of the wrapping machine; an application nozzle for applying a flavoring material to the wrapping-paper web, provided as a stage prior to applying seam glue to the wrapping-paper web supplied to the wrapping machine; a pump for supplying the flavoring material to the application nozzle; and a pump control device for adjusting rate of supply of the flavoring material to the application nozzle by controlling the speed at which the pump is driven, depending on the operating speed of the wrapping machine, wherein the pump control device divides the operating speed of the wrapping machine into a plurality of speed regions and determines an approximation pump characteristic which approximates a relationship between the speed at which the pump is driven and the rate of discharge of the flavoring material from the pump in each of the speed regions, in advance, and determines the speed at which the pump should be driven, depending on the operating speed of the wrapping machine, according to said approximation pump characteristic.
