Method of making smoking articles

A method of producing smoking articles comprising:

• mixing combustible tobacco material with one or more other ingredients including water and a volatile organic liquid to provide a tobacco mixture;
• shaping the mixture under pressure into a discrete coherent mass;
• providing at least one passage through said mass;
• and
• drying said shaped mass,
• the mixture composition being selected and the shaping pressure and drying being controlled to impart to said shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of said shaped mass when ignited.

A method of producing smoking articles comprising:

• mixing combustible tobacco material with one or more other ingredients including a liquid to provide a tobacco mixture;
• shaping the mixture under pressure into a discrete coherent mass by extrusion;
• providing at least one passage through said mass;
• and drying said shaped mass,
• the mixture composition being selected and the shaping pressure and drying being controlled to impart to said shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of said shaped mass when ignited.

A method of producing smoking articles comprising:

• mixing combustible tobacco material with one or more other ingredients including a liquid to provide a tobacco mixture having a solids content of about 55 to 75 weight percent solids;
• shaping the mixture under pressure into a discrete coherent mass;
• and
• providing at least one passage through said mass;
• and
• drying said shaped mass,
• the mixture composition being selected and the shaping pressure and drying being controlled to impart to said shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of said shaped mass when ignited.

A method of producing smoking articles comprising:

• mixing combustible tobacco material with one or more other ingredients including a liquid to provide a tobacco mixture, said ingredients being non-binder materials;
• shaping the mixture under pressure into a discrete coherent mass;
• providing at least one passage through said mass;
• and
• drying said shaped mass,
• the mixture composition being selected and the shaping pressure and drying being controlled to impart to said shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of said shaped mass when ignited.

A method of producing smoking articles comprising:

• mixing combustible tobacco material with one or more other ingredients including a liquid to provide a tobacco mixture;
• shaping the mixture under pressure into a discrete coherent mass by extrusion, said extrusion being carried out such as to provide a substantially cylindrically shaped mass;
• providing at least one passage through said mass;
• and
• drying said shaped mass,
• the mixture composition being selected and the shaping pressure and drying being controlled to impart to said shaped mass a porosity and density such as to substantially occlude gas flow therethrough and a porosity sufficient to support combustion of said shaped mass when ignited.
