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 laminating apparatus for manufacturing a laminate product, the laminating apparatus comprising:
a pressing mechanism configured to apply a laminating force to laminate a foil to a substrate, and
a laminating body that presses the foil to the substrate, the laminating body including a pressure area configured to contact the foil to press and laminate the foil against the substrate during lamination, wherein
the laminating body includes a contact surface of the pressure area, the contact surface of the pressure area being configured to contact the foil as the foil is pressed against the substrate during lamination, the pressure area being configured to transmit a laminating pressure from the pressing mechanism to the foil and the substrate,
only a portion of the contact surface includes an imprinted structure, the imprinted structure including a mirror image of an embossment, the imprinted structure including a thermally stable lacquer provided on the contact surface, and
the laminating apparatus is configured such that an embossing is formed in the foil by pressing the imprinted structure against a portion of the foil while the pressing mechanism laminates the foil to the substrate by pressing the pressure area against the foil.

2. The laminating apparatus according to claim 1 , wherein the laminating body includes a first roller and the pressure area is a first circumferential pressure area at a circumferential surface of the first roller.

3. The laminating apparatus according to claim 2 , wherein the laminating body further includes a second roller, the second roller being configured to provide a counter force to the laminating force applied by the pressing mechanism.

4. The laminating apparatus according to claim 3 , wherein
the second roller having a second circumferential pressure area at a circumferential surface of the second roller,
the second circumferential pressure area has a second contact surface, the second contact surface of the second circumferential pressure area being configured to contact a second foil provided on an opposite side of the substrate from the first foil such that the laminating apparatus presses the first foil against a first surface of the substrate while pressing the second foil against a second surface of the substrate, the first surface of the substrate being opposite from the second surface of the substrate,
at least a portion of the second circumferential pressure area includes a second imprinted structure, the second imprinted structure including a second mirror-image of a second embossment, the second imprinted structure being formed of a thermally stable lacquer provided on the second circumferential contact surface, and
the laminating apparatus is configured such that a second embossing is formed in the second foil by pressing the second imprinted structure against a portion of the second foil while the pressing mechanism laminates the first foil and the second foil to the substrate.

5. The laminating apparatus according to claim 1 , wherein the laminating body includes a first plate and the pressure area is a surface pressure area of the first plate.

6. The laminating apparatus according to claim 5 , wherein the laminating body further includes a second plate, the second plate being configured to provide a counter force to the laminating force applied by the pressing mechanism.

7. The laminating apparatus according to claim 6 , wherein
the second plate having a second surface pressure area,
the second surface pressure area has a second contact surface, the second contact surface of the second surface pressure area being configured to contact a second foil provided on an opposite side of the substrate from the first foil such that the laminating apparatus presses the first foil against a first surface of the substrate while pressing the second foil against a second surface of the substrate, the first surface of the substrate being opposite from the second surface of the substrate,
at least a portion of the second surface pressure area includes a second imprinted structure, the second imprinted structure including a second mirror-image of a second embossment, the second imprinted structure being formed of a thermally stable lacquer provided on the second surface pressure area, and
the laminating apparatus is configured such that a second embossing is formed in the second foil by pressing the second imprinted structure against a portion of the second foil while the pressing mechanism laminates the first foil and the second foil to the substrate.

8. The laminating apparatus according to claim 1 , further comprising a heating unit configured to heat the foil for lamination to the substrate.

9. The laminating apparatus according to claim 1 , wherein the mirror image of the embossment includes a mirror image of a multiple laser image, a country contour, a guilloche pattern, alphanumeric characters, or a machine-readable marking of the laminate product formed upon lamination.

10. The laminating apparatus according to claim 1 , wherein the laminating body includes a high-gloss laminating plate formed of steel, chromium steel, brass, nickel-plating, or chromium plating.

11. The laminating apparatus according to claim 1 , wherein the thermally stable lacquer is a stoving lacquer or a UV-cured lacquer.

12. The laminating apparatus according to claim 1 , wherein the thermally stable lacquer is removable with a cleaner.

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

14. The laminating apparatus according to claim 1 , wherein the laminating body comprises a laminating plate.

15. The laminating apparatus according to claim 1 , wherein the mirror image of the embossment includes a mirror image representation of personalization data of a user of the laminate product.

16. The laminating apparatus according to claim 1 , wherein the imprinted structure is a screen printing printed on the pressure area of the imprinted structure or the imprinted structure is an offset printing printed on the pressure area.

17. The laminating apparatus according to claim 1 , wherein an adhesion promoter is applied to the laminating body, the adhesion promoter facilitating adhesion of the thermally stable lacquer to the to the portion of the contact surface of the pressure area.

18. The laminating apparatus according to claim 1 , wherein laminating apparatus is configured to manufacture a value document, a payment product, an identification document, a chip card or another card-shaped data carrier, a value carrier, a national identity card, a laminated page of a passport, a company ID card, a bank card, a credit card, a payment card, an insurance card, or a membership card.

19. The laminating apparatus according to claim 1 , further comprising an adhesive applicator configured to apply an adhesive or an adhesion promoter to the foil or to the substrate during lamination of the foil to the substrate.

20. The laminating apparatus according to claim 1 , further comprising a foil supplier and a substrate supplier, wherein the foil supplier includes a plastic foil or the substrate supplier includes a plastic substrate or a paper substrate.
