Abstract
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.
