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.

Method, system and apparatus for cutting profiles from natural leaves

An apparatus for cutting cigar wrappers with a selected profile from a natural tobacco leaf, the apparatus comprises a vacuum supporting structure on a leaf receiving member. An arrangement is provided for selecting a cut position on the leaf and oriented with respect to the leaf receiving member and a cutting platen is provided including a leaf supporting surface and an arrangement for creating a vacuum on the surface to support a leaf. The platen is positioned in a known leaf receiving location and a transfer means is provided for transferring the leaf from the leaf receiving member to the leaf supporting surface of the cutting platen. The cutter having the desired profile is provided for cutting the profile from the leaf. The platen is then shifted from its leaf receiving position to a leaf cutting position with the support surface of the platen spaced from the wrapper cutter. After orienting the platen relative to the cutter to align the cutter with the cut position for the leaf the cutter is forced against the platen to cut a wrapper from the leaf. The wrapper is then moved and transferred to a selected location for subsequent use.

Apparatus for cutting cigar wrappers from natural tobacco leaves

There is provided a digital device for creating a series of digital signals indicative of the profile in certain surface variations of a natural tobacco leaf. The light intensity characteristic of an emitted light from various locations on the natural tobacco leaf are scanned in succession across the leaf at parallel positions. The light intensity at the various locations creates a digital signal indicative of whether or not the light intensity is high, low or intermediate. The color profile of the leaf could be created by these signals; however, in accordance with the invention, a digital signal is created when the light intensity signal shifts from one value to another. At that time, a transition signal is created which can be combined to form a transition profile of the leaf which is indicative of the actual profile and color variations of the leaf itself. This information can be used for locating a wrapper cutter at the desired position on the leaf for subsequent cutting of the wrapper from the leaf.
