(14) A first face 3 of the sheet-like information carrier 1 is placed on a first side 5 of the metal sheet 2, in such a way that the metal sheet 2 extends at least beyond one edge 10 of the sheet 1. Then a portion 11 of the metal sheet 2 is bent in a rounding way along an edge of the metal sheet 2, for the portion 11 to bear against and to elastically press on said sheet-like information carrier 1. In some embodiments this is sufficient to hold the sheet-like information carrier 1 firmly in the metal sheet 2 by the pressure of the bent portion 11. In other embodiments abutting edges of the metal sheet 2 can be bent to more firmly hold the sheet-like information carrier 1 within the metal sheet 2.

(15) When bending in a rounding way a portion 11 of the metal sheet 2 along an edge thereof, for the portion 11 to bear against and to elastically press on the sheet 1 the book or booklet cover is formed, where the edge 7 is bent at an angle of 270 degrees or more in relation to a metal sheet 2 with an unbent edge.

(16) In an embodiment of the method the edge 7 is bent at an angle a being in a range between 180 and 270 degrees in relation to a metal sheet 2 with an unbent edge 7, with the effect that a first edge part 8 of the edge 7 of the metal sheet 2 can carve into the material of the sheet-like information carrier 1, providing a holding force.

(17) In another embodiment, the edge 7 is bent at an angle a being 270 degrees in relation to a metal sheet 2 with an unbent edge 7, with the effect that it is possible to provide a contact area corresponding to a material thickness of the metal sheet 2 pressing against a second face 4 of the sheet-like information carrier 1, thereby squeezing the sheet-like information carrier 1 between the edge 7 of the rounded portion 11 of the metal sheet 2 and the first side 5 of the metal sheet 2, providing a holding force.

(18) In another embodiment, the edge 7 is bent at an angle a being in a range between 270 and 360 degrees in relation to a metal sheet 2 with an unbent edge 7, with the effect that it is possible for a second edge part 9 of the edge 7 of the metal sheet 2 to carve into the material of the sheet-like information carrier 1, providing a holding force.

(19) In another embodiment, the edge 7 is bent an angle a being 360 degrees in relation to a metal sheet 2 with an unbent edge 7, with the effect that it is possible to provide a resilient contact area of the second edge part 9 of the portion 11 of the metal sheet 2 pressing against the second face 4 of the sheet-like information carrier 1, providing a holding force.

(20) In another embodiment, the edge 7 is bent at an angle a being more than 360 degrees in relation to a metal sheet 2 with an unbent edge 7, with the effect that it is possible to provide a resilient contact of the portion 11 of the metal sheet 2 pressing against the first face 4 of the sheet-like information carrier 1, providing a holding force.

(21) An example of a machine with a tool for bending a portion of a metal sheet in a rounded way around an edge portion of a sheet-like information carrier is shown in FIGS. 1 to 4, showing different stages during the process.

(22) This is just for mentioning one example, different tools may perform the same bend.

(23) In FIG. 1, the tool includes a lower part 20 and an upper part 21, the lower part 20 including a support surface 22 on which the articles 1, 2 for forming the book or booklet cover is placed and a first tool part 23 having a groove 24 for performing the rounded bending of the portion 11 of the metal sheet 2. The upper part 21 includes a second tool part 25 including an inwardly rounded edge 26 for completing the rounding of the portion 11 of the metal sheet 2, when the tool parts 23, 25 are put together.

(24) When moving the upper part 21 towards the lower part 20, the first tool part 23 is moved towards the edge 7 of the metal sheet 2 and the portion 11 is forced along the rounding in the groove 24 thereby being bent in a rounded way. The traveling distance of the first tool part 23 determines how much of the portion 11 to be bent and the dimension of the groove determines the dimension of the bent edge portion.

(25) In FIG. 2, the first tool part 23 is moved towards the second tool part 25 and the portion 11 of the metal sheet 2 is beginning the bending.

(26) In FIG. 3, the bending is completed and in FIG. 4, the tool parts 23, 25 are moved apart from each other and the end product can be seen.

(27) FIG. 5 shows a sheet-like information carrier 1 placed on a metal sheet 2 before being joined in an edge portion. The sheet 1 includes a first face 3 and an opposite second face 4, where the first face is placed against a first side 5 of the metal sheet 2. The metal sheet 2 has an opposite second side 6, which second side rest on the support surface 22 of the tool during bending. A portion 11 of the metal sheet 2 includes an edge 7 having a first edge part 8 and a second edge part 9. The sheet 1 shows an edge 10.

(28) The product obtained by completion of the process is a book or booklet cover including a metal sheet 2 supporting a sheet-like information carrier 1, which sheet 1 has a first face 3 and an opposite second face 4, with the first face 3 of the sheet 1 on a first side 5 of a metal sheet 2, the metal sheet 2 having a portion 11 that extends beyond at least one edge 10 of the sheet 1, where the portion 11 of the metal sheet 2 has a rounded bend along an edge thereof, the portion 11 elastically pressing against the sheet 1.

(29) In an embodiment as shown in FIG. 7, the metal sheet 2 has an edge 7 which is bent at an angle a in a range between 180 and 270 degrees in relation to a metal sheet 2 with an unbent edge 7. Hereby the first edge 8 carves into the sheet 1 forming a better grip than if the edge 7 of the metal sheet 2 was just folded around the edge of the sheet 1.

(30) In an embodiment as shown in FIG. 6, the metal sheet 2 has an edge 7 which is bent at an angle a being 270 degrees in relation to a metal sheet 2 with an unbent edge 7. The angle a mentioned in the different embodiments are indicated in FIG. 6, which angle a refers to an angular position of the edge 7 compared to an edge 7 of a sheet with an unbent edge.

(31) In embodiments as shown in FIGS. 8, 9 and 10, the metal sheet 2 has an edge 7 which is bent at an angle a being more than 360 degrees (FIG. 10), preferable 360 degrees (FIG. 9), more preferable in a range between 270 and 360 degrees (FIG. 8) in relation to a metal sheet 2 with an unbent edge 7.

(32) As shown in FIG. 8, the second edge 9 carves into the sheet 1 forming a better grip than if the edge 7 of the metal sheet 2 was just folded around the edge of the sheet 1.

(33) Hereby it is possible to retain the sheet-like information carrier 1 in relation to a metal sheet 2, where a portion 11 that extends beyond at least one edge 10 of the sheet 1, where the portion 11 of the metal sheet 2 has a rounded bend along an edge thereof, the portion 11 elastically pressing against the sheet 1 and thereby attaching the two parts together without need to use any adhesive material.
