Abstract
Abstract A consolidated man-made board, such as hardboard, is "post-press" embossed with a contoured embossing plate at a pressure of at least about 1000 psi, 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: 18
Claim 1
Independent Claim
54 words
A method of embossing a decorative man-made board comprising embossing a consolidated man-made board with a contoured embossing plate at a pressure of at least about 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permanently reshape at least one surface of the man-made board.
Claim 2
Independent Claim
54 words
A method of embossing a decorative man-made board comprising embossing a consolidated man-made board with a contoured embossing plate at a pressure of at least about 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permanently reshape at least one surface of the man-made board.
Claim 3
Dependent Claim
35 words
A method as defined in claim 1 wherein the board is embossed at a pressure in the range of about 1000-5000 psi and for a period of time of from about 10 to 240 seconds.
Claim 4
Dependent Claim
22 words
A method as defined in claim 1 wherein said consolidated board is embossed at a temperature in the range of 400°-650° F.
Claim 5
Dependent Claim
35 words
A method as defined in claim 2 wherein the board is embossed at a pressure in the range of about 3000 to 5000 psi and for a period of time from 10 to 60 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
14 words
A method as defined in claim 5 wherein the compressible cushion is porous rubber.
Claim 8
Dependent Claim
17 words
A method as defined in claim 5 wherein the compressible cushion is a sheet of man-made board.
Claim 9
Dependent Claim
13 words
A method as defined in claim 5 wherein the compressible cushion is water-penetrable.
Claim 10
Dependent Claim
18 words
A method as defined in claim 1 wherein the man-made consolidated board is embossed in a platen press.
Claim 11
Dependent Claim
22 words
A method as defined in claim 1 wherein said consolidated board is embossed at a temperature in the range of 400°-550° F.
Claim 12
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 13
Dependent Claim
72 words
In a method of forming a decorative board including depositing fibers onto a surface to form a fibrous mat and compessing said fibrous mat to consolidate said mat into a consolidated board, the improvement comprising embossing said consolidated board with a contoured embossing plate at a pressure of at least 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permanently reshape said board.
Claim 14
Dependent Claim
72 words
In a method of forming a decorative board including depositing fibers onto a surface to form a fibrous mat and compessing said fibrous mat to consolidate said mat into a consolidated board, the improvement comprising embossing said consolidated board with a contoured embossing plate at a pressure of at least 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permanently reshape said board.
Claim 15
Independent Claim
65 words
A method of embossing a decorative man-made board comprising embossing a consolidated man-made board with a contoured embossing plate, without first pre-wetting a surface of said board to be embossed, at a pressure of at least about 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permanently reshape at least one surface of the man-made board.
Claim 16
Independent Claim
65 words
A method of embossing a decorative man-made board comprising embossing a consolidated man-made board with a contoured embossing plate, without first pre-wetting a surface of said board to be embossed, at a pressure of at least about 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permanently reshape at least one surface of the man-made board.
Claim 17
Dependent Claim
80 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 embossing said consolidated board with a contoured embossing plate at a pressure of at least 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permenently reshape said board, without pre-setting said consolidated board prior to embossing.
Claim 18
Dependent Claim
80 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 embossing said consolidated board with a contoured embossing plate at a pressure of at least 1000 psi, at a temperature of at least 400° F. and for a period of time sufficient to permenently reshape said board, without pre-setting said consolidated board prior to embossing.
