Abstract
Tobacco extender material is provided in sheet-like form by contacting tobacco material and/or carbonized material in substantially dry form with a binding agent in substantially dry form, and then subjecting the mixture to a high rate of shear agitation in the presence of a relatively low moisture content. The level of moisture is sufficient to provide activation of the binding agent. The material so processed is further processed using dry forming techniques in order to provide sheets of reconstituted tobacco material and sheets of carbonized material. The sheets of tobacco extender can be cut to the desired size and is useful in the manufacture of cigarettes.
