Abstract

The invention relates to a method and a plant for the treatment of tobacco leaves for the production of cut tobacco for smokable articles, in which stems or winnowings, on the one hand, and the lamina material of the tobacco leaves, on the other, are conditioned separately from each other. The conditioned, non-rolled stems are precut and the conditioned winnowings are rolled and individually respectively or also jointly blended with the conditioned and uncut lamina material; the resulting blend is then cut and dried.
