Abstract

In a method of laminating a transfer layer to a substrate, a transfer layer is provided on a carrier layer. Portions of the transfer layer are selectively removed from the carrier layer using an adhesive panel by heating portions of the adhesive panel corresponding to the portions of the transfer layer, and transferring the portions of the transfer layer from the carrier layer to the adhesive panel. A transfer section of the transfer layer is then transferred from the carrier layer to a surface of the substrate by fracturing the transfer layer along an edge of the transfer section.

First claim

What is claimed is:

1. A method of laminating a transfer layer to a substrate comprising:
providing a transfer layer on a carrier layer;
selectively removing portions of the transfer layer from the carrier layer using an adhesive panel comprising:
heating portions of the adhesive panel corresponding to the portions of the transfer layer; and
transferring the portions of the transfer layer from the carrier layer to the adhesive panel; and

transferring a transfer section of the transfer layer from the carrier layer to a surface of a substrate comprising fracturing the transfer layer along an edge of the transfer section.

2. The method according to claim 1 , wherein transferring a transfer section comprises:
aligning the transfer section with the surface of the substrate;
laminating the transfer section to the surface of the substrate; and
removing the carrier layer from the transfer section.

3. The method according to claim 1 , wherein the substrate is a card substrate.

4. The method according to claim 1 , wherein:
the substrate includes a leading edge, a trailing edge opposite the leading edge, and first and second opposing side edges extending between the leading and trailing edges; and
the transfer section includes a leading edge corresponding to the leading edge of the substrate, a trailing edge corresponding to the trailing edge of the substrate and side edges corresponding to the side edges of the substrate; and
selectively removing portions of the transfer layer comprises removing at least one portion of the transfer layer that adjoins one of the edges of the transfer section.

5. The method according to claim 4 , wherein the portions of the transfer layer include first and second side zones of the transfer layer that respectively extend along the first and second side edges of the transfer section.

6. The method according to claim 4 , wherein fracturing the transfer layer along an edge of the transfer section comprises fracturing the transfer layer along the trailing edge of the transfer section.

7. The method according to claim 1 , wherein selectively removing portions of the transfer layer comprises selectively removing aligned discrete portions of the transfer layer to create at least one perforation line in the transfer layer.

8. The method according to claim 7 , wherein each discrete portion comprises a dot or a dash.

9. The method according to claim 8 , wherein transferring the transfer section from the carrier layer to a surface of a substrate comprises fracturing the transfer layer along one of the perforation lines.

10. The method according to claim 7 , wherein:
the substrate includes a leading edge, a trailing edge opposite the leading edge, and first and second opposing side edges extending between the leading and trailing edges; and
the transfer section includes a leading edge corresponding to the leading edge of the substrate, a trailing edge corresponding to the trailing edge of the substrate and side edges corresponding to the side edges of the substrate; and
at least one perforation line is an edge line that adjoins one of the edges of the transfer section.

11. The method according to claim 10 , wherein the edge line is aligned with one of the trailing edge, the leading edge or one of the side edges of the substrate.

12. The method according to claim 1 , wherein selectively removing portions of the transfer layer comprises selectively removing a line of the transfer layer.

13. The method according to claim 12 , wherein:
the method comprises feeding the transfer layer and carrier layer in a feed direction during selectively removing portions of the transfer layer; and
the line is oriented at an angle of less than 45 degrees to the feed direction.

14. The method according to claim 1 , wherein selectively removing portions of the transfer layer from the carrier layer comprises selectively removing a pattern of the transfer layer.

15. The method according to claim 14 , wherein the pattern is selected from the group consisting of a perforated line, a cross-hatched pattern, a fishbone pattern, and a dot pattern.

16. The method according claim 15 , wherein the pattern comprises a cross-hatched pattern having a plurality of lines, which are oriented at angles of less than 45 degrees to a feed direction in which the transfer layer and the carrier layer are fed during selectively removing portions of the transfer layer.

17. The method according to claim 1 , wherein selectively removing portions of the transfer layer from the carrier layer comprises selectively removing portions of the transfer layer that are within the transfer section.

18. A method of laminating a transfer layer to a substrate comprising:
providing a transfer layer on a carrier layer;
selectively removing at least one perforated line of the transfer layer from the carrier layer using an adhesive panel comprising:
heating portions of the adhesive panel corresponding to discrete portions of the transfer layer that form the perforated line; and
transferring the discrete portions of the transfer layer from the carrier layer to the adhesive panel; and

transferring a transfer section of the transfer layer from the carrier layer to a surface of a substrate comprising fracturing the transfer layer along at least one of the perforated lines.

19. The method according to claim 18 , wherein:
the substrate includes a leading edge, a trailing edge opposite the leading edge, and first and second opposing side edges extending between the leading and trailing edges; and
the transfer section includes a leading edge corresponding to the leading edge of the substrate, a trailing edge corresponding to the trailing edge of the substrate and side edges corresponding to the side edges of the substrate; and
one of the perforated lines extends along one of the edges of the transfer section.

20. The method according to claim 19 , wherein one of the perforated lines extends along the trailing edge of the transfer section.
