Process for manufacturing textured laminate sheet

1. A process for producing a textured laminate sheet, the process comprising:

a) positioning a substrate material adjacent a barbed face of a metal sheet, wherein the barbed face has a plurality of barbs, and the metal sheet has an opposed face opposite the barbed face;

b) forcing the metal sheet and the substrate material together to impale the substrate material on the barbs and secure the substrate material and the metal sheet together as a laminate sheet; and

c) debossing the opposed face to form a plurality of depressions in the laminate sheet so as to texture the laminate sheet.

i) the substrate material has a first face adjacent the barbed face and a second face opposite the first face; and

ii) the process further comprises d) securing a second metal sheet to the second face of the substrate material, wherein the second metal sheet has a second barbed face with a second plurality of barbs, and a second opposed face.

5. The process of claim 4 , wherein step d) is carried out concurrently with step b), and comprises forcing the second metal sheet and the substrate material together to impale the substrate material on the second plurality of barbs.

6. The process of claim 1 , wherein the plurality of depressions are arranged in a regular pattern.

7. The process of claim 1 , wherein the plurality of depressions comprise an array of dimples.

8. The process of claim 1 , wherein steps b) and c) are carried out by a securing and texturing apparatus.

10. The process of claim 9 , wherein steps b) and c) comprise actuating a press to force a plate against the metal sheet and the substrate material to impale the substrate material on the barbs and then deboss the opposed face.

11. The process of claim 8 , wherein step b) further comprises passing the metal sheet and the substrate material between a pair of securing rollers of the securing and texturing apparatus.

12. The process of claim 11 , wherein step c) further comprises passing the laminate sheet between a pair of texturing rollers of the securing and texturing apparatus.

13. The process of claim 12 , wherein the texturing rollers comprise a first roller with a substantially flat contact surface, and a second roller having a contact surface with raised features.

14. The process of claim 1 , further comprising heating at least one of the metal sheet and the substrate material prior to step c).

15. The process of claim 14 , further comprising heating at least one of the metal sheet and the substrate material prior to step b).

16. The process of claim 15 , wherein heating at least one of the metal sheet and the substrate material comprises passing the metal sheet and the substrate material between a pair of heating rollers.

17. The process of claim 1 , wherein the substrate material comprises plastic, rubber, wood, foam, metal, or a combination thereof.

18. The process of claim 1 , wherein:

i) the barbed face has a barbed face footprint;

ii) the substrate material has a first face adjacent the barbed face, and the first face has a first face surface area; and

iii) the first face surface area is less than the barbed face footprint.

19. The process of claim 1 , wherein the substrate material is a latticed sheet having openings therethrough.

20. A process for producing a textured laminate sheet, the process comprising:

a) supplying a laminate sheet to a texturing apparatus, the laminate sheet comprising (i) a metal sheet having a barbed face with a plurality of barbs, and an opposed face opposite the barbed face, and (ii) a substrate material adjacent the barbed face and impaled on the barbs; and

b) in the texturing apparatus, debossing the opposed face to form a plurality of depressions in the laminate sheet and texture the laminate sheet.

21. The process of claim 20 , wherein at least some of the depressions extend from the opposed face into the substrate material.

22. The process of claim 20 , wherein the substrate material has a first face adjacent the barbed face and a second face opposite the first face, and step c) comprises maintaining the second face as planar and non-textured.

23. The process of claim 20 , wherein:

i) the substrate material has a first face adjacent the barbed face and a second face opposite the first face; and

ii) the laminate sheet further comprises a second metal sheet secured to the second face of the substrate material, wherein the second metal sheet has a second barbed face with a second plurality of barbs, and a second opposed face.

24. The process of claim 20 , wherein the depressions are arranged in a regular pattern.

25. The process of claim 20 , wherein the plurality of depressions comprises an array of dimples.

26. The process of claim 20 , wherein step b) further comprises actuating a press to deboss the opposed face.

27. The process of claim 20 , wherein step b) further comprises passing the laminate sheet between a pair of texturing rollers of the texturing apparatus.

28. The process of claim 27 , wherein the texturing rollers comprise a first roller having a substantially flat contact surface, and a second roller having a contact surface with raised features.

29. The process of claim 20 , further comprising heating at least one of the metal sheet and the substrate material prior to step b).

30. The process of claim 29 , wherein heating at least one of the metal sheet and the substrate material comprises passing the metal sheet and the substrate material between a pair of heating rollers.

31. The process of claim 20 , wherein the substrate material comprises plastic, rubber, wood, foam, metal, or a combination thereof.
