Die, die assembly, equipment and method for forming rods of fibrous material

A die for forming a bundle of fibres into a rod, the die comprising a body defining a passage for conducting the bundle of fibres through the die from an inlet to an outlet, a constriction in the passage having an entrance at or downstream of the inlet shaped to form the fibres of the bundle into a desired configuration as the bundle passes through the die, at least one conduit through which a treatment fluid for curing the bundle of fibres may be introduced into the passage, the conduit being arranged to discharge the fluid in the immediate vicinity of the entrance to the constriction and in a direction that is not opposed to the direction of movement of the bundle of fibres through the die,

• wherein the die comprises further conduits through which a fluid may be introduced into the passage for treating fibres therein, said further conduits being constructed and arranged to discharge fluid into an inlet section of the passage upstream of the constriction.
