Abstract (en)
[origin: EP0377344A1] In order to polish, with visible marks, a zone (9) of a surface (2), the unworked zones are masked with a cover (4) having one adhesive face and one face lined with a layer of metal (7) resistant to abrasion, the total thickness (e) of which does not exceed 40 microns, so that the unpolished area along the edge (8) of the cover (4) has a width (l) less than approximately 0.1 mm, which makes it invisible to the naked eye so that the adjacent zones are directly in contact without any visible separation area. <IMAGE>
