<p>A cutting device for trimming printed paper packages in a packaging machine comprising a cutting unit consisting of an upper part (15) and a lower part (16), at least one of the two parts (15, 16) being movable upwards and downwards on passage of a continuous papery material (12) originating from a reel and of flat tubular form bonded transversely and possibly longitudinally by glue and provided with printed portions (10) separated by a neutral strip (29). One (15) of the two parts (15, 16) of the cutting unit carries two blades (25) spaced apart by a distance similar to the width of the strip, which interact with two counter-blades (45) arranged on the other part (16), elastic presser elements (36) being positioned on at least one (15) of the parts of the cutting unit to act to lock the papery material (12) during the cutting action on the strip, removable elements (27) being provided to vary the distance between the blades and counter-blades (45) as the width of the strip (29) varies. <IMAGE></p> |
