Abstract
A smoking article and methods of making the article are described in which a sheet of reconstituted tobacco having an area less than about 100 cm.sup.2 is manually or machine folded into a substantially flat strip of tobacco for smoking. The reconstituted tobacco sheet may be folded about other folded or unfolded strips of tobacco sheet and compressed into a substantially flat smoking article.
Claims46
A sheet of reconstituted tobacco for use in making a smoking article, said sheet having two sides, said sheet having a first fold line defining at least first and second panels, and an adhesive applied to a surface of both the first and second panels on one side of said sheet such that when said sheet is folded upon itself along said first fold line, the adhesive on each panel contacts the surface of the other panel to thereby adhesively secure the panels in direct surface contact with one another to form a substantially flat smoking article.
A method of making a smoking article comprising the steps of:
- providing a sheet of reconstituted tobacco having a given area;
- folding said sheet onto itself along at least one fold line to define at least two panels of said sheet, said panels having inner and outer surfaces;
- and
- pressing an inner surface of one of said panels into contact with the inner surface of another of said panels to form a substantially flat folded smoking article.
A smoking article comprising:
- a sheet of reconstituted tobacco having a given area and a polygonal perimeter with a plurality of edges, said sheet being folded at least once along a first fold line into contact with itself to form a flat folded strip, said fold line being substantially parallel to an edge of said polygonal perimeter;
- and
- adhesive means applied to said reconstituted tobacco sheet for adhesively securing said sheet to itself in said flat folded strip.
A method of making a smoking article comprising the steps of:
- providing a first sheet of reconstituted tobacco having a given area;
- placing a second sheet of reconstituted tobacco onto said first sheet;
- and
- folding said first sheet along at least a first fold line so as to enclose said second sheet within said first sheet with said first and second sheets in substantially parallel planes with respect to one another to thereby form a substantially flat smoking article.
A method of making a smoking article comprising the steps of:
- feeding a first elongated strip of reconstituted tobacco to a folding apparatus;
- folding said first strip of reconstituted tobacco along first and second longitudinal fold lines to form at least three longitudinal panels of said sheet defined by said fold lines;
- and
- pressing said panels together in substantially parallel planes with respect to one another to form a substantially flat folded smoking article.
A smoking article made according to the process comprising the steps of:
- providing a first sheet of reconstituted tobacco having a given area;
- placing a second sheet of reconstituted tobacco onto said first sheet;
- and
- folding said first sheet along at least a first fold line so as to enclose said second sheet within said first sheet with said first and second sheets in substantially parallel planes with respect to one another to thereby form a substantially flat smoking article.
A smoking article comprising:
- a sheet of reconstituted tobacco, said sheet being folded at least once along a first fold line to define at least two substantially planar panels;
- and
- at least one substantially planar strip of tobacco located between said two panels such that said strip and said panels are disposed in substantially parallel planes with respect to one another to form a substantially flat smoking article.
