A method and a device for dividing a whole or half a tobacco leaf into usable portions, for example, binders or wrappers, in which the tobacco leaf is spread on two or more contour knives, the cutting edges of which are pressed across the material of the tobacco leaf, wherein the punched-out tobacco leaf portions are lifted out of the contour knives, and deposited on a carrier by means of a suction box conveyor; the leaf portions are subsequently scanned by a scanning apparatus having an electronic processing and control circuitry, controlling pick-up means to pick-up the approved leaf portions from said carrier and to carry them into a bobbin.
