A cigarette making apparatus comprises an application nozzle for applying a flavoring material to a wrapping-paper web supplied continuously to a wrapping machine, a pump for supplying the flavoring material to the application nozzle, and a pump control device for controlling the pump driving speed depending on the wrapping machine operating speed. The pump control device divides the wrapping machine operating speed into a plurality of speed regions and determines an approximation pump characteristic which approximates a relationship between the pump driving speed 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 wrapping machine operating speed, according to the approximation pump characteristic. Consequently, the flavoring material is applied to the wrapping-paper web in an appropriate amount depending on the wrapping machine operating speed.

Cigarette making apparatus

A cigarette making apparatus includes a cooling-water passage which allows a coolant to circulate along a flavoring-material supply path which connects an application nozzle for applying a flavoring material to a wrapping-paper web and a pump for supplying the flavoring material to the application nozzle, to thereby cool the flavoring material. A cooling unit controls the temperature of the coolant supplied to the cooling-water passage. Specifically, the cooling unit controls the temperature of the flavoring material by selectively activating a first control system for detecting the temperature of the coolant supplied to the cooling-water passage and controlling the temperature of the coolant, and a second control system for detecting the temperature of the flavoring material supplied to the application nozzle and controlling the temperature of the coolant. Since the temperature of the flavoring material is controlled to fix the viscosity thereof, the amount per unit area of the flavoring material applied to the wrapping-paper web is fixed only by controlling the drive of the pump depending on the rate of supply of the wrapping-paper web.

Flavoring-material application device

A double-faced splicing tape of the present invention splices a first web used for forming a tobacco rod and a second web in a stand-by state to and has a plurality of perforations extending in a longitudinal direction of the webs. Furthermore, the present invention provides a feeding device for making the double-faced splicing tape hang toward a feeding position located in between a main delivery path of the first web and a sub-delivery path of the second web.

A removing apparatus for rod-like articles comprises a removing drum ( ) as part of a transport path for the articles such as cigarettes, double filter cigarettes and filter cigarettes in a filter cigarette manufacturing machine, and many transport grooves ( ) formed on the outer circumferential surface of the drum ( ) for receiving the articles. Adjacent grooves ( ) have suction holes ( ) at different axial positions thereof. While passing through a suction holding region (A) of the removing drum ( ), the adjacent transport grooves ( ) receive holding pressure for the articles, from the corresponding holding passages ( ) of the region (A) through the suction holes ( ). The passages ( ) extend longer than the pitch of the transport grooves ( ). When compressed air is supplied to a passage ( ), the passage ( ) allows the compressed air to blow out from connected suction holes ( ) to thereby remove the article from the corresponding transport groove ( ).
