ABSTRACT:
A method for producing tobacco in calendered foil form from a mixture of pre-comminuted tobacco, a powdered cellulose derivative binder, water and an organic solvent in which the solvent is mixed with the dry mixture of binder and tobacco to swell and moisten the binder, then the water is added and mixing continued to produce a homogeneous granular mass which is calendered into a smooth continuous foil. The solvent contains a liquid which boils below 100.degree.C. (a lower alcohol, ketone, haloalkane, ester or ether) and a liquid which boils above 100.degree.C. (a polyhydric alcohol or potassium lactate solution). The homogeneous granular mass can be rolled into a foil on a single three-roll mill or calender.
