ABSTRACT OF THE DISCLOSURE A device for determining continuously the hardness of a smokable article, more particularly a cigarette, from the mechanical properties of rod of tobacco fibres during the manufacture of this smokable article, which ascer- tains the temperature of the former finger which compacts the rod of tobacco fibres to a predetermined diameter dependent on the diameter of the finished smokable article. This temperature measurement, which can be carried out by means of a thermocouple element, a resistance thermometer or a semiconductor temperature sensor, represents an exact reproducible measure of the hardness of the smokable article which is produced with this rod of tobacco fibres.
