Abstract
The invention provides an appliance for localized heating of a polymer material surface to be repaired by blowing a hot fluid inside a confinement chamber (2) that is defined by a deformable cap (1). The cap (1) is made of a blanket (6) incorporating a framework (7) for shaping the confinement chamber (2) under the effect of tensions applied locally by the framework (7) to the blanket (6) in its general plane (P). Force generator means (9) cause the framework (7) to change between a flexible state in which the framework (7) is arranged in the general plane of the blanket (6), and a rigid state for shaping the confinement chamber (2). The force generator means (9) comprise a force generator source that produces a suction, and the framework (7) is made up of strips of felt (8, 8′) housed in a pouch of the blanket (6).
