Abstract

A laminating body for laminating a foil onto a substrate includes a pressure area on which there is imprinted a structure which forms an embossing in the foil upon lamination of the foil onto the substrate.

First claim

The invention claimed is:

1. A method for laminating a foil onto a substrate to form a laminate product, the method comprising:
providing a laminating body configured to press the foil to the substrate, the laminating body including a pressure area with a contact surface configured to contact the foil, the pressure area being configured to transmit a laminating pressure from a pressing mechanism to the foil and the substrate;
forming, by imprinting, an imprinted structure on the contact surface of the pressure area of the laminating body, the imprinted structure including a mirror image of an embossment, wherein only a portion of the contact surface includes the imprinted structure; and
laminating the foil to the substrate by pressing the imprinted structure on the contact surface of the pressure area against the foil with a laminating force applied to the foil and the substrate by the pressing mechanism, wherein the imprinted structure is embossed into the foil while the pressing mechanism laminates the foil to the substrate,
wherein the imprinted structure is imprinted on the pressure area with a removable lacquer.

2. The method according to claim 1 , wherein the removable lacquer includes a stoving lacquer or a UV-cured lacquer.

3. The method according to claim 1 , wherein the imprinted structure is configured to form in the foil upon lamination at least one embossing which represents at least one of a multiple laser image, a country contour, a guilloche pattern, alphanumeric characters, and a machine-readable marking of the laminate product formed upon lamination.

4. The method according to claim 1 , wherein the pressure area further comprises an additional structure that includes depressions that extend within the laminating body beyond a surface level of the pressure area.

5. The method according to claim 4 , wherein the additional structure of the pressure area is formed by at least one of etching, milling, or engraving.

6. The method according to claim 1 , wherein the imprinted structure represents personalization data of a user of the laminate product.

7. The method according to claim 1 , wherein the imprinted structure is imprinted on the pressure area by means of screen printing or offset printing.

8. The method according to claim 1 , wherein the imprinted structure is imprinted on the pressure area with a removable lacquer that is a thermally stable lacquer.

9. The method according to claim 1 , wherein individualization data or personalization data are imprinted in the step of forming the imprinted structure on the contact surface of the pressure area.

10. The method according to claim 1 , wherein the imprinted structure is imprinted such that the structure forms in the foil upon lamination at least one embossing which is tactilely perceptible or represents at least one of a multiple laser image, an image, alphanumeric characters and an aid for technical processing of a laminate product formed upon lamination.

11. The method according to claim 1 , wherein the removable lacquer is configured to be removable with a cleaner.

12. A method for making a laminating body configured to laminate a foil onto a substrate to form a laminate product, the method comprising:
providing the laminating body such that the laminating body is configured to press the foil to the substrate, the laminating body including a pressure area with a contact surface configured to contact the foil, the pressure area being configured to transmit a laminating pressure from a pressing mechanism to the foil and the substrate;
forming, by imprinting, an imprinted structure on the contact surface of the pressure area of the laminating body, the imprinted structure including a mirror image of an embossment, wherein only a portion of the contact surface includes the imprinted structure,
wherein the imprinted structure is configured to be embossed into the foil while laminating the foil to the substrate by pressing the imprinted structure on the contact surface of the pressure area against the foil and the substrate with the pressing mechanism such that the imprinted structure is embossed into the foil while the pressing mechanism laminates the foil to the substrate,
wherein the imprinted structure is imprinted on the pressure area with a removable lacquer.

13. The method according to claim 12 , wherein the imprinted structure is configured to form in the foil upon lamination at least one embossing which represents at least one of a multiple laser image, a country contour, a guilloche pattern, alphanumeric characters, and a machine-readable marking of the laminate product formed upon lamination.

14. The method according to claim 12 , wherein the removable lacquer includes a stoving lacquer or a UV-cured lacquer.

15. The method according to claim 12 , further comprising a step of forming an additional structure in the contact surface of the pressure area, the additional structure including depressions that extend within the laminating body beyond a surface level of the pressure area,
wherein the additional structure of the pressure area is formed by at least one of etching, milling, or engraving.

16. The method according to claim 12 , wherein individualization data or personalization data are imprinted in the step of forming the imprinted structure on the contact surface of the pressure area.

17. The method according to claim 12 , wherein the imprinted structure is imprinted on the pressure area by means of screen printing or offset printing.

18. The method according to claim 12 , wherein the structure is imprinted on the pressure area with a removable lacquer that is a thermally stable lacquer.
