<p>A heat gun nozzle (20) provides a fan-shaped flow of air having a temperature variation along the fan. This provides for a variation of the shrink rate when the fan-shaped airflow is applied to heat shrink plastic film. Both symmetric and asymmetric embodiments of the heat gun nozzle (20) have an inlet portion mountable on a conventional heat gun outlet and an outlet portion providing the desired fan-shaped airflow with a duct portion connecting the two. The nozzle outlet can be concave or convex depending on the contour of the surface to be covered. A method of using the heat gun nozzle (20) is also disclosed.</p> |
