<p>A fluid injection device (40) and method of injecting a fluid are disclosed for injecting and distributing a fluid, such as a gas, liquid or combination thereof, to a continuous, multifilament filter two used in the manufacture of filters for smokable tobacco products. The injection device comprises a converging tongue portion (82) from which a nozzle block (84) is suspended and rigidly supported. A nozzle conduit (86) with a plurality of feed holes (96) is formed in the nozzle block for delivering the fluid to a precise location in the advancing filter tow during its formation and consolidation into a filter rod. Additives, such as flavorants, may be injected into the two or the tow may be further bloomed by a gas, such as air, to decrease tow usage. <IMAGE></p> |
