CUTTER FOR PRINTED SUBSTRATES

摘要

The invention relates to a cutter for cutting printed substrates, having a supporting plane adapted to receive a printed substrate comprising a plurality of images separated by a plurality of edges perpendicular to each other in a feeding direction (F), and a plurality of cutting units suitable for cutting the printed substrate along said edges in a longitudinal direction (L), parallel to the feed direction (F), and in a transverse (T), perpendicular to the feeding direction (F). Each cutting unit has a pair of parallel blades, spaced apart 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 the blades during cutting, and a connecting arm which extends from a frame of the cutting unit on which the blades are mounted to the backing plane in a direction opposite to the cutting direction. The connecting arm is parallel to the blades and is arranged between the blades on a plane (P) parallel to the planes (A, B) on which the blades lie, and the portion of the backing plane between the area arranged underneath the blades and the area where the connecting arm is fixed has a through opening.

1. 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.
