Abstract
Abstract A sheet metal cutting device incorporating a sheet feed table on which a bottom blade and bottom transverse blade are mounted integrally, a top blade borne in a pivotable beam and a transverse top blade mounted perpendicularly to the latter, said transverse blade being mounted about the axis of said beam in a vertical plane perpendicular to the cutting plane of the top blade and being guided at the sides by adjustable guide elements. The transverse top blade is mounted to pivot on a lateral prolongation of the axis of rotation of the beam and the two top blades are pivoted independently of one another and can be individually operated each by its own separate actuating element.
