In the production of expanded material from a sheet material strip ( 4 ), in particular, a metal strip, cuts ( 2 ) are introduced into the material strip ( 4 ), by way of at least one cutting unit ( 5 ), using laser, water or electron streams, whereupon the material strip ( 4 ) is subjected to a drawing by way of a drawing device ( 28 ). The cuts in the material strip ( 4 ) are introduced by running the cutting unit ( 5 ), perpendicular to the longitudinal or transport direction ( 7 ) of the material strip, in the form of perpendicular cuts ( 2 ), along perpendicular lines ( 3 ), perpendicular to the longitudinal or transport direction ( 7 ). |
