PURPOSE:To readily add a large amount of a flavoring agent with good accuracy by opening a fiber tow, converting a flavoring agent meltable by heating into the form of a solution and applying the flavoring agent to the surface thereof. CONSTITUTION:A crimped acetate fiber tow 2 is continuously taken out and opened with air using banding jets 3, 4 and 5. A plasticizer is added thereto in the form of droplets in a plasticizer adding device 26. A flavoring agent, e.g. l-menthol or vanillin is then melted and sent from a flavoring agent heating vessel 23, fed with a heating gear pump 24 and fused from a heating nozzle 22 onto the surface of the fiber. The resultant fiber is subsequently fed to a tongue 12 with an air jet 11, rolled in roll paper 6 and cut with a cutter 18 to afford the objective flavoring cylindrical unit 36. |
