Abstract
Rods are manufactured by shredding strips of sheet-like reconstituted tobacco material into a plurality of strands of about 1/32 inch width. The strands are gathered into a rod-like shape and circumscribed by paper wrap in order to provide a continuous rod. The continuous rod is severed at regular intervals to provide a plurality of rods of the desired length. The resulting rods have a plurality of substantially longitudinally extending strands provided from shredded sheet-like material. The rods are useful as cigarette rods or in the manufacture of cigarette filter elements.
Claims27
A filter rod for the preparation of cigarette filter elements, the rod comprising a plurality of individual strands provided from fibrous, nonwoven sheet-like reconstituted tobacco material, wherein the strands extend generally along the longitude of the rod and are contained in a circumscribing wrap, and wherein the width of each individual strand is greater than the thickness thereof.
The rod of claim 17 wherein the circumscribing wrap is a paper wrap.
A substantially cylindrical cigarette filter element comprising a filter medium and a circumscribing plug wrap, wherein the wrap covers the longitudinally extending surface of the filter medium such that the ends of the filter medium are open in order to permit the passage of air and smoke therethrough, and wherein the filter medium includes a plurality of individual strands which extend along the general longitude of the filter element, which strands are provided from fibrous nonwoven sheet-like reconstituted tobacco material, and the width of each individual strand is greater than the thickness thereof.
A cigarette comprising a rod of smokable material axially aligned with and having attached to one end thereof, a substantially cylindrical cigarette filter element having a filter medium and a circumscribing plug wrap, wherein the wrap covers the longitudinally extending surface of the filter medium such that the ends of the filter medium are open in order to permit the passage of air and smoke therethrough, and wherein the filter medium includes a plurality of individual strands, which strands are provided from fibrous, nonwoven, sheet-like reconstituted tobacco material, and the width of each individual strand is greater than the thickness thereof.
A cigarette comprising a rod of smokable material axially aligned with and having attached to one end thereof, two filter elements in sequence, one of which filter elements is a substantially cylindrical cigarette filter element having a filter medium and a circumscribing plug wrap, wherein the wrap covers the longitudinally extending surface of the filter medium such that the ends of the filter medium are open in order to permit the passage of air and smoke therethrough, and wherein the filter medium includes a plurality of individual strands, which are provided from fibrous, nonwoven, sheet-like reconstituted tobacco material, and the width of each individual strand is greater than the thickness thereof.
