Abstract

There is disclosed a method of manufacturing an interactive surface, comprising: providing an adhesive surface on one side of a substrate; providing a grid array adjacent said adhesive surface; heating the adhesive surface to activate/reactivate it; and bonding the grid array to the one side of substrate.

Claims

1. A method of manufacturing an interactive surface, comprising:

providing an adhesive surface on one side of a substrate;

providing a grid array adjacent said adhesive surface;

heating the adhesive surface to activate/reactivate it; and

bonding the grid array to the one side of the substrate to form a bonded structure.

2. The method according to claim 1 wherein the step of providing an adhesive surface comprises applying a coating of adhesive.

3. The method according to claim 2 wherein the step of applying a coating comprises a roller process technique.

4. The method according to claim 1 wherein the adhesive comprises a low cost adhesive.

5. The method according to claim 1 wherein the adhesive is rigid at operational temperatures of the interactive surface.

6. The method according to claim 1 in which another side of the substrate forms a work surface.

7. The method according to claim 6 further comprising the step of applying a protective coating to the work surface.

8. The method according to claim 7 wherein the step of applying the protective coating uses a roller process technique.

9. The method according to claim 1 wherein the step of heating the adhesive layer comprises infra-red heating.

10. The method according to claim 1 wherein the step of bonding the grid array to the one side of the substrate comprises applying the grid array and the substrate together.

11. The method according to claim 10 further comprising the step of providing a resilience to the applying force to accommodate for any unevenness in the surface of the adhesive layer.

12. The method according to claim 11 wherein the step of providing a resilience comprises providing a resilient layer on the other side of the substrate, to which side an applying force is applied.

13. The method according to claim 1 wherein the bonded structure provides a smooth surface on the one side of thesubstrate.

14. The method according to claim 1 wherein the bonded structure provides a uniform surface on the one side of thesubstrate.

15. The method according to claim 1 wherein the heating step results in the grid being embedded in the adhesive, and thereby fixed to the one surface of thesubstrate.

16. The method according to claim 1 further comprising the step of combining a further substrate with the bondedstructure.

17. The method according to claim 16 wherein the further substrate is provided with a pressure sensitive hot melt adhesive layer on one side thereof, which side is arranged to face the one side of the bonded structure, the method further comprising pressing the further substrate and bonded structure together to form a laminate structure.

18. The method according to claim 17, further comprising the step of turning back any portions of the grid protruding from the bonded structure over the further substrate.

19. The method according to claim 17, further comprising the step of fitting a side extrusion around the edges of the laminate structure.

20. The method according to claim 1 wherein the interactive surface is a whiteboard assembly arrangement.

21. The method according to claim 1 wherein the interactive surface is a graphics tablet.

22. An interactive surface maufactured by a method that comprises:

providing an adhesive surface on one side of a substrate;

providing a grid array adjacent said adhesive surface;

heating the adhesive surface to activate/reactivating it; and

bonding the grid array to the one side of the substrate to form a bonded structure.
