<p>A machine for cutting leathers has a bearing structure and an operating element exhibiting a rotation axis and three distinct work planes each arranged about the rotation axis and provided with an aspirating plate that is activatable/deactivatable such as to retain or release the leathers. The operating element successively positions each work plane at three successive and distinct positions with respect to the bearing structure: a first position in which the leathers can be positioned and stretched above the work plane and held stretched thereon, a second position in which the work plane with the leathers stretched and retained thereon is located below a cutter, and a third position wherein the leathers can be unloaded from the work plane by force of gravity following deactivation of the respective aspirating plate.</p> |
