Abstract

Abstract A consolidated man-made board, such as hardboard, is wetted on one surface and thereafter embossed with a contoured embossing plate at a pressure of at least about 1000 p.s.i., at a temperature in the range of about 400°-550° F. and for a period of time sufficient to permanently re-shape the surface of the consolidated board.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 81 words
A method of embossing a decorative man-made board comprising wetting the surface of a consolidated man-made board with an aqueous liquid in an amount sufficient to wet substantially the entire surface to be embossed, embossing the wetted man-made board with a contoured embossing plate at a pressure of at least about 1000 p.s.i., at a temperature in the range of about 400°-550° F. and for a period of time sufficient to permanently reshape at least one surface of the man-made board.
Claim 2
Independent Claim 81 words
A method of embossing a decorative man-made board comprising wetting the surface of a consolidated man-made board with an aqueous liquid in an amount sufficient to wet substantially the entire surface to be embossed, embossing the wetted man-made board with a contoured embossing plate at a pressure of at least about 1000 p.s.i., at a temperature in the range of about 400°-550° F. and for a period of time sufficient to permanently reshape at least one surface of the man-made board.
Claim 3
Dependent Claim 36 words
A method as defined in claim 1 wherein the wetted board is embossed at a pressure in the range of about 1500-5000 p.s.i. and for a period of time of from about 1 to 60 seconds.
Claim 4
Dependent Claim 12 words
A method as defined in claim 1 wherein the liquid comprises water.
Claim 5
Dependent Claim 36 words
A method as defined in claim 2 wherein the wetted board is embossed at a pressure in the range of about 3,000 to 5,000 p.s.i. and for a period of time from 1 to 30 seconds.
Claim 6
Dependent Claim 18 words
A method as defined in claim 1 wherein the man-made consolidated board is embossed against a compressible cushion.
Claim 7
Dependent Claim 28 words
A method as defined in claim 5 wherein an adhesive is disposed between the board and the cushion to adhere the cushion to the board material during hot-pressing.
Claim 8
Dependent Claim 14 words
A method as defined in claim 5 wherein the compressible cushion is porous rubber.
Claim 9
Dependent Claim 17 words
A method as defined in claim 5 wherein the compressible cushion is a sheet of man-made board.
Claim 10
Dependent Claim 13 words
A method as defined in claim 5 wherein the compressible cushion is water-penetrable.
Claim 11
Dependent Claim 18 words
A method as defined in claim 1 wherein the man-made consolidated board is embossed in a platen press.
Claim 12
Dependent Claim 101 words
In a method of forming a decorative board including depositing fibers onto a surface to form a fibrous mat and compressing said fibrous mat to consolidate said mat into a consolidated board the improvement comprising wetting a surface of said consolidated board with an aqueous liquid in an amount sufficient to wet substantially the entire surface to be embossed, embossing the wetted surface of said consolidated board with a contoured embossing plate at a pressure of at least 1000 p.s.i., at a temperature of at least 400° F and for a period of time sufficient to permanently re-shape said wetted surface.
Claim 13
Dependent Claim 101 words
In a method of forming a decorative board including depositing fibers onto a surface to form a fibrous mat and compressing said fibrous mat to consolidate said mat into a consolidated board the improvement comprising wetting a surface of said consolidated board with an aqueous liquid in an amount sufficient to wet substantially the entire surface to be embossed, embossing the wetted surface of said consolidated board with a contoured embossing plate at a pressure of at least 1000 p.s.i., at a temperature of at least 400° F and for a period of time sufficient to permanently re-shape said wetted surface.
Claim 14
Dependent Claim 16 words
In the method as defined in claim 11 wherein the aqueous liquid includes sodium xylene sulfonate.
