Abstract
A method for forming a creasing (10) on a paper item (1) comprises: providing a predetermined pattern to be marked on the paper item; marking said pattern on a surface (S) of said paper item to provide a score line (2, 3, 4) on said paper item; wherein said pattern comprises at least one score line (2) which extends alternatively along opposed directions with respect to a centreline (C), and which defines adjacent portions (5a, 5b) of said paper item; and folding said paper item such that said adjacent portions (5a, 5b) project at least partially outwards with respect to the surface (S) of the paper item outside said adjacent portions (5a, 5b).

A method for forming a creasing (10) on a paper item (1) comprising:
- providing a predetermined pattern to be marked on the paper item;
- marking said predetermined pattern on a surface (S) of said paper item to provide at least one score line (2, 3, 4) on said paper item;
- wherein said pattern comprises at least one score line (2) which extends alternatively along opposed directions with respect to a centreline (C), and which defines adjacent portions (5a, 5b) of said paper item;
- and
- folding said paper item such that said adjacent portions (5a, 5b) project at least partially outwards with respect to the surface (S) of the paper item outside said adjacent portions (5a, 5b),
- wherein the adjacent portions (5a, 5b) comprise anchoring parts (6) that remain attached to the paper item and end parts (7) that project at least partially outward with respect to the surface (S) of the paper item outside said adjacent portions (5a, 5b).
A method for forming a creasing (10) on a paper item (1), said method comprising:
- providing a predetermined pattern to be marked on the paper item;
- and
- marking said predetermined pattern on a surface(S) of said paper item to provide at least one score line (2, 3, 4) on said paper item;
- wherein said pattern comprises at least one score line (2) which extends alternatively along opposed directions with respect to a centreline (C), and which defines adjacent portions (5a, 5b) of said paper item,
- wherein the adjacent portions (5a, 5b) are adapted to project at least partially outwards with respect to the surface(S) of the paper item outside said adjacent portions (5a, 5b), and comprise anchoring parts (6) adapted to remain attached to the paper item and end parts (7) that project at least partially outward with respect to the surface(S) of the paper item outside said adjacent portions (5a, 5b) when said paper item (1) is folded, and
- wherein the step of marking said predetermined pattern on a surface(S) of said paper item to provide at least one score line (2, 3, 4) is carried out by means of a laser beam.
A paper item (1) comprising a predetermined pattern marked on a surface(S) of said paper item to provide at least one score line (2, 3, 4) for forming a creasing, wherein said pattern comprises at least one score line (2) which extends alternatively along opposed directions with respect to a centreline (C), and which defines adjacent portions (5a, 5b) of said paper item, wherein said at least one score line (2, 3, 4) of said predetermined pattern has a depth between 20% and 60% of the thickness of the paper item and the adjacent portions (5a, 5b) are adapted to project at least partially outwards with respect to the surface(S) of the paper item outside said adjacent portions (5a, 5b), and comprise anchoring parts (6) adapted to remain attached to the paper item and end parts (7) that project at least partially outward with respect to the surface(S) of the paper item outside said adjacent portions (5a, 5b) when said paper item (1) is folded.
