摘要: A tip for a smokable article comprises a tubularly arranged covering material with an air-pervious ventilation zone, and also a tubular core which is within the covering material and which contains no filter material. The air-impervious tube wall of this core has a tubular outlet region directed towards the smoker and also a conically tapering inlet region provided with a small inlet aperture and directed towards the tobacco. Between the core and the covering material, through-flow ducts are formed by appropriate shaping of the surface of the core and these in conjunction with the remaining shape of the core define the draw resistance of this tip, and at the same time dilute the smoke through the air aspirated through the ventilation zone.This core can be manufactured from an extruded tubular blank of synthetic plastic material, in which the ducts are formed sectionwise by means of eccentrics.
