Patent No. US4073300 (titled "Method Of Making Russian Cigarettes") was filed by Molins on Nov 10, 1975. The application was issued on Feb 14, 1978.
In the mid-1970s when '300 was filed, cigarette manufacturing typically involved discrete steps of forming tubes, filling them with tobacco, and then wrapping the combined components. At a time when continuous high-speed manufacturing was desirable, hardware constraints made the precise and rapid manipulation of individual cigarette components non-trivial.
The disclosed invention provides a method for continuously manufacturing Russian cigarettes by intercalating streams of tobacco and tube portions, wrapping the alternating stream, and then dividing the rod into individual cigarettes. This integration of the manufacturing process streamlines production. The invention also provides a novel cigarette structure with a tube member having an inner roll and an outer roll joined by a reverse fold, enhancing structural integrity and potentially simplifying assembly.
This patent contains zero claims, therefore there are no independent or dependent claims to analyze.
