constructive arrangement in engraving of ring for identification of birds.

摘要

constructive arrangement in washer engraving for bird identification, consisting essentially of engraving on carbide (tungsten) and ceramic washers, however, as an inventive principle the use of inverted engraving, that is, the laser is projected on the washer and the engraving is done by wearing out the areas of the different engraving quadrants of the piece, thus evidencing the identification characters in the form of letters and combined numbers that are in high relief, so this improvement in the engraving process aims primarily to reduce the possibility of cloning these washers a since the laser used in this form of engraving is in high power and the engraving is extremely difficult and consists of cylindrical main body (1), beveled inner edge (2), hollow inner region (3), perimeter engraving quadrants due to wear of the laser (4), characters resulting from embossing (5).
