Abstract: A fluid injection device and method of injecting and distributing a fluid, such as a gas, liquid or combination thereof, to a continuous, multifilament filter tow used in the manufacture of filters for smokable tobacco products. The injection device includes a converging tongue portion from which a nozzle block is suspended and rigidly supported. A nozzle conduit with a plurality of feed holes 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 tow or the tow may be further bloomed by a gas, such as air, to decrease tow usage.
