ABSTRACT:
Disclosed is a method and apparatus for processing baled tobacco leaves to separate the lamina portions of the leaves from the stem portions. The bale is cut symmetrically, crosswise to its length, into three or preferably five separate sections, of different characteristic types. A center section is cut from the middle of the bale. On each side of the center section a second section is cut; and two end sections are preferably cut, one at each end of the bale. The different types of sections have different lamina-to-stem ratios, and are processed differently. The second sections are coarsely threshed, to dislodge the larger lamina portions of the leaves from the stem portions therein, and the coarsely threshed material is separated into a first light fraction (comprising mostly lamina) and a first heavy fraction (enriched in stem content). The center section can be combined with the light fraction and can be dried and packed without the necessity of further threshing. If end sections are cut, the first heavy fraction is combined with them and is more finely threshed, to dislodge remaining lamina portions from the stem portions therein.
