Abstract
There is provided a method, system and apparatus for cutting a profile, such as a cigar wrapper, from a natural leaf, such as a tobacco leaf, wherein the leaf is spread and supported on a support surface in a random position. Thereafter, a leaf facsimile or image, including the leaf outline and surface imperfections, is developed and at least one cut position for the wrapper is located in an area excluding the leaf outline and surface imperfections. This cut position is recorded and converted to digital data. The wrapper is then cut from the leaf at an actual cut position corresponding to the located cut position determined by the digital data. Also, the facsimile is created by a back lighting arrangement which illuminates color variations and surface imperfections, as well as the leaf outline, so that leaf color variations can be included in the facsimile or image.
