<p>An apparatus and method for cutting lamina portions of tobacco leaves (320) without severing at least some of the stems of the tobacco leaves (320). The cutting can be carried out using one or more cutting flows of water, air or focused energy such as laser or ultrasound. The cuts in the lamina portions can be intersecting cuts which allow easier separation of the lamina from the stems by a separator (240) or during threshing (250) of the leaves. The leaves can be conveyed (120) to a cutting device (130) comprising one or more fixed or reciprocating cutting flows which provide the desired cuts in the lamina portions of the leaves. The leaves can be passed through a separator (240) which separates the stems from the lamina after which the remaining stem containing material can be passed through the threshing line (250).</p> |
