To determine the filling capacity of tobacco, a predetermined quantity of tobacco is filled into a volume of known cross-section forming part of a press, closed on one side by a movable plunger, and the length of the tobacco column and the force acting on the tobacco during compression of the tobacco by the plunger are measured as a function of time. The output data are processed by at least one c...
