Patent number: 8820328Abstract: The invention relates to a method of producing cut tobacco material, whereby a tobacco initial material is heated and placed under pressure and once heated and placed under pressure, the material is fed through a shearing gap and expanded and defibrated. It further relates to a device for producing cut tobacco material with a pressure chamber, which has a tobacco material inlet at the low-pressure end and a tobacco material outlet at the pressure end and a conveyor system for conveying the tobacco material from the inlet to the outlet, and the tobacco material outlet has a gap through which the material passes and expands, and the gap has walls which can be moved towards one another. It further relates to a smoking article containing such a cut, defibrated tobacco material product and the use of a plug screw feeder-extruder with a shearing gap outlet for defibrating tobacco material.Type: GrantFiled: December 23, 2010Date of Patent: September 2, 2014Assignee: British American Tobacco (Germany) GmbHInventors: Uwe Werner Ehling, Gerald Schmekel, Dietmar Franke, Matthias Link
