Abstract
The invention provides a method of making tobacco rod in which method the tobacco filler material of the rod is subjected to radio frequency heating before feeding to a rod making machine. The elevated temperature increases the pliability of the tobacco filler, thus reducing its degradation in the rod making machine and enhancing the physical properties, e.g. ends stability, of the tobacco rods thus produced.
