Cutter for printed substrates

A cutter for cutting printed substrates, said cutter comprising a supporting plane suitable to receive along a feeding direction (F) a printed substrate comprising a plurality of images separated by a plurality of edges that are perpendicular to each other, and a plurality of cutting units suitable to cut said printed substrate along said edges in a longitudinal direction, parallel to said feeding direction (F), and in a transverse direction (T), perpendicular to said feeding direction (F), characterized in that

• each cutting unit comprises a pair of blades parallel to each other and mutually spaced at a distance corresponding to the width of the edges, a backing plane, arranged underneath the supporting plane of the cutter and suitable to provide a backing surface to said blades during a cutting operation, and a connecting arm extending from a frame of the cutting unit, on which the blades are mounted, to said backing plane in a direction opposite to the cutting direction, and in that
• said connecting arm is parallel to the blades and lies on a plane (P) parallel to the planes (A, B) on which the blades lie, and the portion of the backing plane comprised between the area arranged underneath the blades and the area wherein the connecting arm is fixed comprises a through opening.
