ABSTRACT:
A hand held, fluid driven film applique tool is disclosed for applying a film having an adhesive backing to a surface having a protrusion. The applique tool comprises a tool head including a hollow cylinder having an open end for receiving the protrusion and a closed end, the hollow cylinder being surrounded by an annular surface which is relatively flat and smooth. An elastomeric plug is slidably received by the hollow cylinder, the plug having a head portion forming the closed end of the hollow cylinder and a fluid pressure surface to which is applied a fluid under pressure to drive the elastomeric plug toward the open end of the hollow cylinder. A spring is provided for biasing the elastomeric plug away from the open end of the hollow cylinder and a switch is included for connecting a source of fluid under pressure to the fluid pressure surface of the elastomeric plug. Further, a handle is furnished for holding the tool. In operation, the tool head is placed over the protrusion so that the open end of hollow cylinder receives at least the protrusion and the film overlying the protrusion and the annular surface stretches and presses the film surrounding the protrusion against the surface. By applying the source of fluid under pressure to the fluid pressure surface, the head portion of the elastomeric plug is driven into contact with the protrusion to press the film firmly against the protrusion to assure that the film is flatly and completely applied at the protrusion.
