Abstract (en)

[origin: EP3854228A1] The present invention belongs to the technical field of heating cigarette manufacturing, and in particular to a non-combustible cigarette based on flocking technology and a manufacturing method of the cigarette. The cigarette includes a cigarette paper layer (31), which is a hollow cylindrical structure. The inner wall of the cigarette paper layer (31) is provided with an adhesive layer (21), and tobacco filler granules (11), tobacco filler filaments or tobacco filler fibers are fixedly bonded on the adhesive layer (21). The manufacturing method includes a flocking process and a cigarette-rolling process. The process automatically flocks filamentous, fibrous or granular tobacco to the surface of the cigarette paper, and then connects to the cigarette-rolling process to obtain the non-combustible cigarette. When the cigarette is filled with the tobacco filler granules, the complex process of using a plugging device at the open end of the cigarette is eliminated. When the cigarette is filled with the tobacco filler filaments or fibers, the thermal resistance of heat transferring in the radial direction of the cigarette is reduced, thereby overcoming the shortcomings of the existing heat-not-burn cigarette such as large thermal resistance, slow heat transfer rate and uneven heating.
