<p>It is provided an apparatus for treating leather materials intended for covering motorcar dashboards provided with invisible airbags, in which a supporting base (3) receives the leather material to be submitted to treatment on an upper surface thereof, in such a manner that said leather material has one side resting on the base which corresponds to the visible side of the material in a three-dimensional sheet (4) when said dashboard is covered with it and a free side intended for being concealed under the same dashboard-covering conditions. A work head (12) carrying a cutting tool operates on the sheet material (4) for making a weakening line of predetermined depth thereon. The operating surface of the supporting base (3) has a three-dimensional extension the shape of which substantially matches that of the corresponding surface of the dashboard to be covered with the leather material. The apparatus enables precise scores to be made even on surfaces having a strong three-dimensional extension.</p> |
