<p>A tobacco sheet reconstitution process and draw down apparatus which comprises drawing down a sheet of tobacco- containing extrudate extruded from an extruder 2 the draw down is achieved by passing the extrudate around one or more draw down drums of a diameter within the range of 30-100cm, the extrudate is in contact with at least 50% of the circumferential surface of at least one draw down drum 10, 11; two draw down drums are used, the degree of contact of the extrudate with the circumference of the drum may be less than the contact with the first drum and is preferably at least 45% of the circumference of the second drum, water cooling and chilling means in the draw down drums assists in contraction of the extrudate, aiding the wrap around and friction contact of the extrudate with draw down drum(s). <IMAGE></p> |
