Abstract
A method and apparatus for producing a tobacco rod of predictable characteristics whereby the tobacco filler is tempered prior to forming into a rod in a cigarette making apparatus. The tobacco filler is tempered prior to entry into the maker region to a temperature of from 32.degree. F. to just below ambient. Heat exchange coils are provided in a feed chamber wherein the tobacco filler is recirculated for tempering to desired temperature prior to being fed to the maker on a continuous basis.
