Abstract
Disclosed are new fuel components for smoking articles such as cigarettes, new methods of making such fuel components, and cigarettes or other smoking articles incorporating the new fuel components. Fuel components for smoking articles are formed by continuously extruding a composition to form a preselected shape, circumscribing the continuously extruded composition with a layer of material to form a wrapped rod or composite member, preferably bonding the fuel element to the layer of material, and cutting the resulting composite member into predetermined lengths for use in assembling smoking articles.
Claims22
A method for continuous formation of a fuel component for a smoking article, the method comprising:
- continuously extruding a combustible composition to form extrudate having a preselected shape, continuously wrapping the extruded composition with a compressible, resilient retaining layer of fibrous web material to form a composite member, and bonding the retaining layer to the combustible composition.
A method for continuous formation of a fuel component for a smoking article, the method comprising:
- continuously extruding a combustible composition to form extrudate having a preselected shape, and continuously circumscribing the extruded composition with a compressible, resilient retaining layer of web material to form a composite member, and bonding the retaining layer to the combustible composition;
- wherein the method further includes wetting the retaining layer prior to the circumscribing step.
A method for continuous formation of a fuel element component for a smoking article, the method comprising:
- continuously extruding a composition comprising a carbonaceous material to form extrudate having a preselected shape, continuously wrapping the extruded composition with a compressible, resilient layer of fibrous web material to form a composite member, bonding the fibrous material layer to the extrudate, and cutting the resulting composite member into predetermined lengths.
A method for continuous formation of a fuel component for a smoking article, the method comprising:
- continuously extruding a composition comprising a carbonaceous material to form extrudate having a preselected shape, circumscribing the continuously extruded composition with a compressible, resilient layer of web material to form a composite member, and cutting the resulting composite member into predetermined lengths,
- further including wrapping the composite member to determine the outer diameter prior to the cutting step,
- wherein, prior to the circumscribing step, the method further includes wetting the circumscribing layer.
A component for a smoking article, the component comprising an extruded carbonaceous fuel element, the outer surface of which is circumscribed with a compressible, resilient layer of web material adhered with the longitudinal surface of the fuel element.
A component for a smoking article, the component comprising an extruded fuel element composition, the outer surface of which is circumscribed with a compressible, resilient layer of material adhered to the longitudinal surface of the extruded composition,
- wherein the extruded composition comprises a carbonaceous material;
- and
- wherein the resilient layer comprises a gathered web of treated paper.
A component for a smoking article, the component comprising an extruded carbonaceous fuel element composition, the outer surface of which is circumscribed with a compressible, resilient layer of material adhered to the longitudinal surface of the fuel element,
- wherein the resilient layer comprises a gathered web of paper.
A smoking article comprising a fuel component, the fuel component comprising a predetermined length of extruded composition, the outer surface of which is circumscribed with a compressible, resilient layer of web material adhered to the longitudinal surface of the extruded composition, the extruded composition comprising a carbonaceous material.
