A nozzle assembly adapted for repeatably positioning the nozzle in a precise relationship to an article and method for using it in a seam-sealing operation, the nozzle assembly comprising a nozzle, an alignment plate, and an arm forming a unitary nozzle assembly, and an air conduit for connecting the nozzle to a source of pressurized air. The nozzle assembly may further comprise a base for mounting the integral nozzle unit alignment plate, 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 may be oriented to avoid visually obstructing the article receiving air flow. The nozzle 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 may further include a thermocouple assembly attached to the integral nozzle unit for measuring the air stream temperature near the point of discharge from the nozzle. |
