A method for realising cartons for packing, characterised in that it comprises the following steps: feeding a cardboard band for packing along an advancement direction which is parallel to the development direction of the cardboard band; making a first score line and a second score line on the cardboard band, such that the first score line and the second score line are parallel to the development direction and the following are identified: a central sector comprised between the first score line and the second score line; a first lateral sector comprised between the first score line and a first lateral end of the cardboard band; and a second lateral sector comprised between the second score line and a second lateral end of the cardboard band which is opposite the first lateral end; identifying on the cardboard band band regions that are consecutive to one another; carrying out, on each band region, at least a first cut, a second cut, a third cut and a fourth cut made in a transversal direction to the development direction of the cardboard band such that: the first cut and the second cut are performed on the first lateral sector and extend up to the first score line, such that a first closing wing, a first reinforcing wing and a second reinforcing wing are defined in first lateral sector, the first closing wing being interposed between the first reinforcing wing and the second reinforcing wing; the third cut and the fourth cut are performed on the second lateral sector and extend up to the second score line, such that a second closing wing, a third reinforcing wing and a fourth reinforcing wing are defined on the second lateral sector, the second closing wing being interposed between the third reinforcing wing and the fourth reinforcing wing; the first closing wing is opposite the second closing wing, the first reinforcing ring is opposite the third reinforcing wing, the second reinforcing wing is opposite the fourth reinforcing wing; cutting the cardboard band transversally such as to separate the above-cited band regions from one another, thus obtaining cartons for packing. feeding a cardboard band for packing along an advancement direction which is parallel to the development direction of the cardboard band; making a first score line and a second score line on the cardboard band, such that the first score line and the second score line are parallel to the development direction and the following are identified: a central sector comprised between the first score line and the second score line; a first lateral sector comprised between the first score line and a first lateral end of the cardboard band; and a second lateral sector comprised between the second score line and a second lateral end of the cardboard band which is opposite the first lateral end; identifying on the cardboard band band regions that are consecutive to one another; carrying out, on each band region, at least a first cut, a second cut, a third cut and a fourth cut made in a transversal direction to the development direction of the cardboard band such that: the first cut and the second cut are performed on the first lateral sector and extend up to the first score line, such that a first closing wing, a first reinforcing wing and a second reinforcing wing are defined in first lateral sector, the first closing wing being interposed between the first reinforcing wing and the second reinforcing wing; the third cut and the fourth cut are performed on the second lateral sector and extend up to the second score line, such that a second closing wing, a third reinforcing wing and a fourth reinforcing wing are defined on the second lateral sector, the second closing wing being interposed between the third reinforcing wing and the fourth reinforcing wing; the first closing wing is opposite the second closing wing, the first reinforcing ring is opposite the third reinforcing wing, the second reinforcing wing is opposite the fourth reinforcing wing; cutting the cardboard band transversally such as to separate the above-cited band regions from one another, thus obtaining cartons for packing.
