Abstract
In a method and an apparatus for controlling the physical properties of a rod of smokable material the actual values of at least two physical properties, in particular resistance to draw and hardness or deformation of the tobacco rod or of the smokable article, are detected; the differences between said actual values and predetermined desired values are determined and control signals derived therefrom; said control signals are compared with each other and the particular instantaneously largest control signal is supplied to a single actuator, that is an ecreteur or a hopper. An auto-selector circuit with maximum selection is used to compare the control signals.
