Abstract

The present invention provides a wood-based composite panel that is not susceptible to top surface edge swell, and methods of making the panel.

Claims (34)

1. A wood-based composite panel, comprising:

a top surface having a top perimeter including a first set and a second set of opposing sides; and

a bottom surface, opposite the top surface, having a bottom perimeter including a first set and a second set of opposing sides, the first set and the second set of opposing sides of the bottom surface corresponding in relative positioning to the first set and the second set of opposing sides of the top surface;

wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is about ⅛ inch to about ¾ inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface, such that the top surface is not susceptible to edge swell,

wherein the wood-based composite panel is an oriented strand board (OSB) panel.

2. The panel of claim 1 comprising a first and second set of opposing side surfaces, the side surfaces having a first set and second set of opposing sides, the distance between the first set of opposing sides corresponding to the distance between the first or second set of opposing sides of the bottom surface, wherein the distance between the second set of opposing sides of at least one side surface is at least about 1/1000 inch less than an average distance between the top and bottom surfaces.

3. The panel of claim 2 , wherein the distance between the second set of opposing sides of one side surface is less than an average distance between the top and bottom surfaces.

4. The panel of claim 2 , wherein the distance between the second set of opposing sides of at least two side surfaces is less than an average distance between the top and bottom surfaces.

5. The panel of claim 2 , wherein the distance between the second set of opposing sides of at least three side surfaces is less than an average distance between the top and bottom surfaces.

6. The panel of claim 2 , wherein the distance between the second set of opposing sides of at least four side surfaces is less than an average distance between the top and bottom surfaces.

7. The panel of claim 1 comprising a first and second set of opposing side surfaces, the side surfaces having a first set and second set of opposing sides, the distance between the first set of opposing sides corresponding to the distance between the first or second set of opposing sides of the bottom surface, wherein the distance between the second set of opposing sides of at least one side surface is at least about 5/1000 inch less than an average distance between the top and bottom surfaces.

8. The panel of claim 1 comprising a first and second set of opposing side surfaces, the side surfaces having a first set and second set of opposing sides, the distance between the first set of opposing sides corresponding to the distance between the first or second set of opposing sides of the bottom surface, wherein the distance between the second set of opposing sides of at least one side surface is up to about 1/10 inch less than an average distance between the top and bottom surfaces.

9. The panel of claim 1 comprising a first and second set of opposing side surfaces, the side surfaces having a first set and second set of opposing sides, the distance between the first set of opposing sides corresponding to the distance between the first or second set of opposing sides of the bottom surface, wherein the distance between the second set of opposing sides of at least one side surface is at least about 20/1000 inch to about 43/1000 inch less than an average distance between the top and bottom surfaces.

10. The panel of claim 1 comprising a first and second set of opposing side surfaces, the side surfaces having a first set and second set of opposing sides, the distance between the first set of opposing sides corresponding to the distance between the first or second set of opposing sides of the bottom surface, wherein the distance between the second set of opposing sides of at least one side surface is at least about 27/1000 inch to about 35/1000 inch less than an average distance between the top and bottom surfaces.

11. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is up to about 2 inches less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

12. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is up to about 1 inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

13. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is up to about 15/16 inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

14. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is up to about ⅞ inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

15. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is about 35/100 inch to about 43/100 inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

16. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is more than 1/16 inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

17. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is more than ⅛ inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

18. The panel of claim 1 wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is more than ⅜ inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface.

19. The panel of claim 1 , wherein the panel is configured for tongue and groove fitting on at least one side.

20. The panel of claim 1 , wherein the panel is configured for tongue and groove fitting on two sides.

21. A wood-based composite panel, comprising:

a top surface having a top perimeter including a first set and a second set of opposing sides; and

a bottom surface, opposite the top surface, having a bottom perimeter including a first set and a second set of opposing sides, the first set and the second set of opposing sides of the bottom surface corresponding in relative positioning to the first set and the second set of opposing sides of the top surface;

wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is about ⅛ inch to about ¾ inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface, such that the top surface is not susceptible to edge swell.

22. A wood-based composite panel, comprising:

a top surface having a top perimeter including a first set and a second set of opposing sides; and

a bottom surface, opposite the top surface, having a bottom perimeter including a first set and a second set of opposing sides, the first set and the second set of opposing sides of the bottom surface corresponding in relative positioning to the first set and the second set of opposing sides of the top surface;

a first and second set of opposing side surfaces, the side surfaces having a first set and second set of opposing sides, the distance between of the first set of opposing sides corresponding to the distance between the first or second set of opposing sides of the bottom surface, wherein the distance between the second set of opposing sides of at least one side surface is at least about 27/1000 inch to about 35/1000 inch less than an average distance between the top and bottom surfaces;

wherein the distance between at least one of the first set or the second set of opposing sides of the top surface is about ⅛ inch to about ¾ inch less than the distance between the corresponding first set or second set of opposing sides of the bottom surface, such that the top surface is not susceptible to edge swell,

wherein the wood-based composite panel is an oriented strand board (OSB) panel.
