Abstract
In order to remove a plate made from a material that can be heated by electromagnetic induction and retained on a supporting member by a heat-fusible adhesive, an inductor is displaced facing at least one strip of the plate in order to heat the strip by induction and heat the adhesive by conduction until the adhesive softens, and a tearing tool is driven so as to tear out the heated strip by hot-peeling. The inductor and the tearing tool are displaced jointly relative to the plate and the supporting member by means of a mobile frame, which is displaced on a stationary frame on which the supporting member and the plate are fixed.
Claims8
A device for removing an electromagnetic induction sensible leading edge protective cap bonded by a heat-fusible adhesive onto a rotor blade, wherein said device comprises:
- at least one stationary frame on which said rotor blade fitted with said cap is fixed;
- at least one mobile frame, which can be displaced relative to the stationary frame and bearing at least one mobile inductor and at least one mobile tearing tool, which are displaced respectively opposite at least one strip of said cap and in contact with said strip and substantially along the latter or between said strip and said rotor blade when said mobile frame is displaced relative to said stationary frame, whereby successive strips of the cap may be torn off;
- first means for controlling the displacement of said mobile frame together with said mobile inductor and said mobile tearing tool on said stationary frame in at least a first direction, substantially across the length of at least one strip of cap to be removed;
- and
- second means for controlling the positioning of said inductor and/or said tearing tool by displacement on said mobile frame in at least a second direction, transversely to said first direction, and substantially across the width of said strip of cap.
A device as claimed in clam 1, wherein said tearing tool includes a roller which rolls on said rotor blade, tearing therefrom a strip of cap that has just been heated.
