Abstract
A heat gun nozzle and a method of using the nozzle includes a fan-shaped or wing-shaped flow of air having a temperature and/or airflow variation along the nozzle. This provides for a variation in the shrink rate when the fan-or wing-shaped airflow is applied to heat shrink plastic film. Both symmetric and asymmetric embodiments of the heat gun nozzle have an inlet portion mountable on a conventional heat gun outlet and an outlet portion providing the desired fan-shaped heat air flow with a duct portion connecting the two. In preferred embodiments, the nozzle outlet can be concave or convex depending upon the contour of the surface which is to be covered. The present invention also relates to the method of using such a heat gun nozzle permitting a substantial reduction in the number of heat gun passes required to successfully heat shrink film onto a compound curved surface.
