Abstract

See full text

In a method of making lengths of smoking-material rod, particularly cigaret lengths, smoking material and wrapper-web material are each continuously fed to a rod maker operable to wrap and seam-seal the wrapper material about the smoking material to provide smoking material rod which is then fed to a cutter for cutting the rod into lengths. Smoke-modifying agent is applied by spray intermittently to one of the materials during their feeding to the rod maker so that, in each of the lengths, the smoke-modifying agent is distributed over one end zone which is accounted for by a few puffs, in the smoking of the length. The smoke modifying agent is of low volatility and low porosity migration.
