A method for realising a cardboard blank from a cardboard for packaging and for boxing at least one article with the cardboard blank, wherein the at least one article comprises a first flank, a second flank opposite the first flank, a third flank comprised between the first flank and the second flank, a fourth flank comprised between the first flank and the second flank and opposite the third flank, a bottom and an upper face opposite the bottom, comprising:
- providing a cardboard for packaging which is flat;
- making a first score line and a second score line on the cardboard for packaging, so that the first score line and the second score line are parallel to one another and so that the following are identified:
- a central sector comprised between the first score line and the second score line, comprising a first portion, a second portion and a third portion, the first portion being interposed between the second portion and the third portion;
- a first lateral sector comprised between the first score line and a first lateral end of the of the cardboard for packaging and a second lateral sector 11 comprised between the second score line and a second lateral end of the cardboard for packaging, which is opposite the first lateral end;
- carrying out a first cut, a second cut, a third cut and a fourth cut each made in a transversal direction to the first score line and to the second score line so that:
- the first cut and the second cut are carried out on the first lateral sector and extend from the first lateral end of the cardboard for packaging to the first score line, so that a first closing flap is identified in the first lateral sector, foldable towards the first portion and having a first edge and a second edge opposite one another, a first reinforcing flap foldable towards the second portion and a second reinforcing flap foldable towards the third portion, the first closing flap being interposed between the first reinforcing flap and the second reinforcing flap;
- the third cut and the fourth cut are carried out on the second lateral sector and extend from the second lateral end of the cardboard for packaging to the second score line, so that a second closing flap is identified in the second lateral sector, foldable towards the first portion and having a third edge and a fourth edge opposite one another, a third reinforcing flap foldable towards the second portion and a fourth reinforcing flap foldable towards the third portion, the second closing flap being interposed between the third reinforcing flap and the fourth reinforcing flap;
- if the dimensions of a box to be obtained exceed, by a predetermined value, the dimensions of the at least one article to be boxed, cutting the cardboard for packaging in order to reduce the dimensions of the box to be obtained;
- if the cardboard for packaging is an integral part of a band of cardboard for packaging, cutting the cardboard for packaging so as to obtain a sheet of cardboard for packaging;
- arranging the at least one article on the first portion so that the bottom of the at least one article is arranged resting on the first portion;
- folding the first closing flap with respect to the first score line to cover at least the first flank of the at least one article;
- folding the second closing flap with respect to the second score line to cover at least the second flank of the at least one article;
- folding the second portion to cover at least the third flank of the at least one article with the consequence that the first reinforcing flap is projecting with respect to the first closing flap once the first closing flap has been folded and the third reinforcing flap is projecting with respect to the second closing flap once the second closing flap has been folded;
- folding the third portion to cover at least the fourth flank and the upper face of the at least one article with the consequence that the second reinforcing flap is projecting with respect to the first closing flap once the first closing flap has been folded and the fourth reinforcing flap is projecting with respect to the second closing flap once the second closing flap has been folded;
- and
- tightening a strapping band about the second portion, the first reinforcing flap, the first closing flap, the second reinforcing flap, the third portion, the fourth reinforcing flap, the second closing flap and the third reinforcing flap, so as to cause:
- the folding of the first reinforcing flap towards the first closing flap with a consequent covering of the first edge of the first closing flap;
- the folding of the second reinforcing flap towards the first closing flap with a consequent covering of the second edge of the first closing flap;
- the folding of the third reinforcing flap towards the second closing flap with a consequent covering of the third edge of the second closing flap;
- the folding of the fourth reinforcing flap towards the second closing flap with a consequent covering of the fourth edge of the second closing flap.
