<p>A method for the optical projection of profiles on the work surface ( 1 ) of a machine ( 100 ) for automatic cutting of flat articles ( 2 ) includes the following operation steps: positioning of a flat article ( 2 ) on the work surface; definition of a profile ( 3, 3 A) on the flat article ( 2 ) by the projection, on the latter, of a first light beam ( 4 ); orientation by rotation, with respect to an axis orthogonal to the surface ( 1 ), and positioning of the profile ( 3, 3 A) on the flat article ( 2 ), and selection of the profile; definition of the profile ( 3, 3 A) on the flat article by the permanent optical projection thereon of a second light beam ( 5 ), and contemporary deactivation of the first light beam ( 4 ). The invention further proposes a machine for automatic cutting of flat articles with two projectors as required by the method.</p> |
