Abstract
The disclosure is of a method and apparatus for stripping leaf lamina from tobacco leaf stems. The apparatus comprises two pairs of opposed rollers in tandem relationship. The first set of rollers is driven at a fixed speed and serves to engage and feed tobacco leaf to the second set of rollers which are driven at a relatively higher speed. When the second pair of rollers engages the stem of the tobacco leaf, the stem is yanked away from the leaf lamina, which is held back by its engagement with the first pair of feed rollers. In this way stripping of the leaf lamina occurs. The disclosure is also of a method of destemming tobacco leaf, employing the apparatus of the invention. The method simulates the desirable results of hand stripping without an expenditure of hand stripping labor. The method is also advantageous in that it permits one to destem tobacco leaves having relatively low moisture content and at ambient temperatures, thereby effecting a considerable savings in energy expenditure.
