A fluid application device, a nozzle assembly and a method of applying a fluid onto a strand of material provided. The fluid application device includes an applicator head and a nozzle assembly. The nozzle assembly includes a guide slot for receiving a strand of material. The nozzle assembly further includes an orifice, spaced from the guide slot, configured to discharge a first fluid to onto the strand, and at least one outlet, adjacent to the orifice, for discharging a second fluid to act on the first fluid. The method includes positioning the strand at the closed end of the guide slot so that the strand is spaced a predetermined distance from the orifice, feeding the strand through the guide slot at a predetermined speed, applying the first fluid onto the strand from the orifice and discharging the second fluid from the at least one outlet.
