A nozzle assembly (20) adapted for repeatably positioning the nozzle (18) in a precise relationship to an article and method for using it in a seam-sealing operation, the nozzle assembly (20) comprising a nozzle (18), an alignment plate (80), and an arm (82) forming a unitary nozzle assembly (20), and an air conduit for connecting the nozzle to a source of pressurized air. The nozzle assembly (20) may further comprise a base for mounting the integral nozzle unit alignment plate (80), and a linear actuator connected to the base for moving the base along a linear path from a first, operating position to a second, standby position. The nozzle (18) may be oriented to avoid visually obstructing the article receiving air flow. The nozzle (18) may be attached to a seam-sealing machine and may discharge a heated air stream of sufficient temperature to melt seam-sealing tape adhesive backing to adhere such tape to fabric, and the nozzle assembly (20) may further include a thermocouple assembly (95) attached to the integral nozzle unit (20) for measuring the air stream temperature near the point of discharge from the nozzle (18). |
