Latest Patents

Among his notable inventions is the "Method for making a hollow filter rod." This invention encompasses an apparatus designed to produce a hollow filter rod efficiently. The apparatus features a mandrel through which a supplied length of tubing is passed. A nozzle surrounds the mandrel, shaping a stream of fibrous filter material around it, while forming means wrap a web of paper around both the fibrous material and the tubing. This configuration ensures that the tubing is accurately centered within the filter rod. The hollow filter includes a rigid, non-deformable tube that defines a smoke passage, allowing control over the draw resistance to regulate the amount of unfiltered smoke. Additionally, the concentric layer of filter material and the perforated outer wrap facilitate air passage into the filter layer.

Another significant patent is the "Apparatus for measuring smoke dilution in a vented-filter cigarette." This advanced device allows a puff generator to draw a volume of smoke and air through a vented-filter cigarette. The process causes air to be drawn from a ventilation cylinder, resulting in piston movement to a dead center position. The distance traveled by the piston serves as a direct measure of the ventilation effect on the filter, producing a digital readout of the degree of ventilation.

Career Highlights

Throughout his career, Sigmon has collaborated with prominent companies in the tobacco industry, including Liggett Group Inc. and Liggett & Myers, Incorporated.
