  • Forming sheet from reconstituted tobacco
    Patent number: 4337783
    Abstract: A method of forming sheet from reconstituted tobacco involves the formation of a high solids content slurry of which the particle size is less than 60 B.S. mesh. The slurry is then extruded through a single pair of rollers onto a wire mesh conveyor, or onto a continuous casting band which is itself supported by one of the rollers. The high solids content reduces the energy costs in drying the extruded sheet and the use of a single pair of rollers reduced the costs of the machinery.
