The invention relates to a coaxial tobacco cartridge with an inner core of a first tobacco blend, a sheath for the inner core, an outer jacket of a second tobacco blend, a sheath of high air permeability and an associated filter element. The coaxial tobacco cartridge is not smokable independently, but can be used by persons to make their own coaxial cigarettes, by inserting it in an appropriate cigarette-paper tube or wrapping it in a cigarette-paper strip.

Tobacco cartridge

The invention relates to a cigarette paper having the conventional burning additives and fillers containing from 20 to 50% by weight of bast fibres of fine fibrillation, with which a degree of grinding of at least 85 SR is produced. The cigarette paper produced according to this formulation has a pore structure which greatly promotes diffusion, in particular diffusion of carbon monoxide.

Cigarette paper

An apparatus is provided for determining the burning and/or glowing rate of a smokable article. The apparatus comprises a sensor for sensing the incandescent zone of the smokable article and a drive apparatus for moving the sensor along a path parallel to the direction of burning and glowing of the smokable article. A control circuit, including first switches is coupled to the sensor and the drive apparatus, for stopping the drive apparatus and thereby the movement of the sensor when the sensor detects a predetermined radiation intensity and for starting the drive apparatus and thereby the sensor when the sensor detects a radiation intensity other than the predetermined intensity when the first switches are in a first state and for starting the drive apparatus and thereby the movement of the sensor means when the sensor detects a predetermined radiation intensity and for stopping the sensor when the sensor detects a radiation intensity other than the predetermined intensity when the first switches are in a second state.
