ABSTRACT:
An extruder nozzle for an apparatus for producing tobacco fiber from a paste, pulp, mash or slurry of comminuted botanics, which may or may not contain tobacco, binders, plasticizers and organic and inorganic salts, comprises a nozzle surface formed with a multiplicity of orifices through which strands of the dryable composition are extruded. Distributed among the orifices are openings for a compressed gas, e.g. compressed air, which passes along the fibers in the direction of extrusion thereof and hence applies an entraining force to the strands tending to break them off into fibers.
