Abstract: Finished and semi-finished ophthalmic lenses are made by polymerizing the monomer while it is sealed in an oxygen-impermeable envelope.

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.

Abstract: Methods and apparatus are taught for decorating sheet material such as, for example, cigar wrappers. The apparatus includes feeder means for drawing the sheet material toward and around a center cylinder; decorating means for imparting a predetermined pattern on the sheet material; coloring means for coloring the sheet material and drawing and rewind means for drawing the sheet material from the center sheet guide means.An alternate embodiment teaches methods and apparatus for use with at least two layers of sheet material such as, for example, cigar wrapper sheet material, one of such layers being decorated and colored and then laminated to the other layer.

Abstract: A cigar wrapper is provided having opposed surfaces and a predetermined thickness, said wrapper having a vein-like pattern embossed through the thickness thereof resulting in a raised, vein-like pattern formed on one of the surfaces and a complimentary depressed vein-like pattern formed on the opposite surface. The one surface of the wrapper is treated with colorants to simulate a natural tobacco leaf, and the depressed vein-like pattern on the opposite surface is filled with a filler material. In a preferred embodiment, a second sheet of manufactured cigar wrapper material is laminated in juxtaposition to the opposite surface of the decorated sheet.
