Abstract

Methods and apparatus to remove gas and vapor from a panel for a decorative layer are disclosed. An example apparatus includes a first press plate of a hot press to engage a first surface of a panel. The hot press is to apply heat to the panel via the first press plate to cure resin of the panel. A first portion of the first press plate is composed of a permeable material to remove at least one of gas or vapor from the panel to deter the at least one of gas or vapor from exerting a pressure on a decorative layer to be coupled to the panel to deter separation of a portion of the decorative layer from the panel.

First claim

What is claimed is:

1. An apparatus comprising:
a first press plate of a hot press to engage a first surface of a panel, the hot press to apply heat to the panel via the first press plate to cure resin of the panel, the first press plate including:
a first portion including a permeable material to remove at least one of gas or vapor from the panel to deter the at least one of gas or vapor from exerting a pressure on a decorative layer to be coupled to the panel to deter separation of a portion of the decorative layer from the panel; and
a second portion including a second material, the first portion and the second portion forming an outer surface of the first press plate, the second material different than the permeable material, the second portion defining a venting channel, the first portion filling the venting channel so that at least a portion of the outer surface formed by the first portion and the second portion is flat, the at least the portion of the outer surface to deter the first press plate from forming protrusions on the first surface of the panel.

2. The apparatus of claim 1 , wherein the permeable material enables water vapor to traverse therethrough and deters liquid resin from traversing therethrough.

3. The apparatus of claim 1 , further including a coating of moisture absorption material applied to the first press plate that captures moisture to further deter the at least one of gas or vapor from exerting the pressure on the decorative layer to be coupled to the panel.

4. The apparatus of claim 1 , wherein the permeable material is to contact the panel when the first press plate engages the panel.

5. The apparatus of claim 4 , wherein the second material includes a low permeability material that impedes water vapor and liquid resin from traversing therethrough.

6. The apparatus of claim 5 , wherein the venting channel extends to an outer edge of the first press plate to enable the at least one of gas or vapor to move away from the panel.

7. An apparatus comprising:
a first press plate of a hot press to engage a first surface of a panel, the hot press to apply heat to the panel via the first press plate to cure resin of the panel, a first portion of the first press plate including:
a permeable material to remove at least one of gas or vapor from the panel to deter the at least one of gas or vapor from exerting a pressure on a decorative layer to be coupled to the panel to deter separation of a portion of the decorative layer from the panel; and
a liquid-resistant layer to engage the first surface of the panel, the permeable material and the liquid-resistant layer to enable the at least one of gas or vapor to traverse therethrough to enable the at least one of gas or vapor to be removed from the panel, the liquid-resistant layer to impede liquid resin of the panel from traversing to the permeable material to impede the liquid resin from deterring the at least one of gas or vapor from traversing through the permeable material wherein the liquid-resistant layer is composed of biaxial stretch polytetrafluoroethylene and the permeable material is composed of at least one of a porous metallic material, a porous ceramic material or an open-cell polymer foam.

8. The apparatus of claim 1 , further including a second press plate of the hot press to engage a second surface of the panel opposite the first surface to further remove the at least one of gas or vapor from the panel.

9. An apparatus comprising:
means for curing; and
means for engaging a surface of a panel, the means for curing to apply heat to the panel via the means for engaging to cure resin of the panel, the means for engaging including:
means for removing at least one of gas or vapor from the panel to deter the at least one of gas or vapor from exerting a pressure on a means for decorating to be coupled to the panel to deter separation of a portion of the means for decorating from the panel;
means for impeding a fluid flow, the means for removing and the means for impeding forming an outer surface of the means for engaging; and
venting means defined by the means for impeding the fluid flow, the means for removing filling the venting means so that at least a portion of the outer surface formed by the means for removing and the means for impeding is flat, the at least the portion of the outer surface to deter the means for engaging from forming protrusions on the surface of the panel.

10. A method comprising:
contacting a first press plate of a hot press to a first surface of a panel, a first portion of the first press plate including a permeable material filling one or more venting channels, the venting channels defined by a second material of the first press plate, the first portion of the first press plate and the second material of the first press plate forming an outer surface of the first press plate, at least a portion of the outer surface formed by the first portion and the second material being flat, the at least the portion of the outer surface to deter the first press plate from forming protrusions on the first surface of the panel, the permeable material to enable at least one of gas or vapor to traverse therethrough, the second material different than the permeable material;
applying heat to the panel, via the first press plate, to cure resin of the panel; and
removing at least one of gas or vapor from the panel via the permeable material of the first press plate to deter the at least one of gas or vapor from exerting a pressure on a decorative layer to be coupled to the panel to deter separation of a portion of the decorative layer from the panel.

11. The method of claim 10 , wherein contacting the first press plate of the hot press to the first surface of the panel causes the first press plate to engage the panel to enable the at least one of gas or vapor to be removed from the panel via the permeable material of the first press plate.

12. The method of claim 10 , further including applying a vacuum to the panel to further enable the at least one of gas or vapor to be removed from the panel.

13. The method of claim 10 , wherein removing the at least one of gas or vapor from the panel via the permeable material includes venting the at least one of gas or vapor through the permeable material, the one or more venting channels defined by the outer surface of the first press plate, the venting channels extending to an outer edge of the first press plate to enable the at least one of gas or vapor to vent away from the panel.

14. The method of claim 10 , further including:
contacting a second press plate of the hot press to a second surface of the panel opposite the first surface, a portion of the second press plate composed of permeable material; and
applying heat to the panel via the second press plate to further remove the at least one of gas or vapor from the panel via the permeable material of the second press plate to deter separation of the portion of the decorative layer from the panel.

15. The apparatus of claim 1 , wherein a permeability of the second material is less than a permeability of the permeable material.

16. The apparatus of claim 9 , wherein the means for removing includes a first material and the means for impending impeding includes a second material, the second material less permeable than the first material.

17. An apparatus comprising:
a first press plate of a hot press to engage a first surface of a panel, the hot press to apply heat to the panel via the first press plate to cure resin of the panel, the first press plate including:
a first portion including a perm
