Abstract
Abstract This invention relates to a method for producing cutting and creasing plates used in die cutting operations which plates generally comprise a hard metal base plate having a raised counter pattern thereon. In accordance with the method of this invention, a first sheet of material from which the counter pattern is to be formed is bonded to a backing sheet, and grooves are formed through the first sheet in accordance with the desired counter pattern. Next, the outer surface of the first sheet is bonded to a surface of a plate. Then the backing sheet is removed from the first sheet and the excess of the first sheet removed from the plate leaving those sections of the first sheet bonded to the plate which define the counter pattern, thus forming a cutting and creasing plate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A method of producing a cutting and creasing plate having a counter pattern thereon for die cutting operations comprising the steps of bonding a first sheet from which the counter pattern is to be formed to a backing sheet, forming grooves in the first sheet in accordance with the desired counter pattern, which grooves extend completely through the first sheet but not completely through the backing sheet, bonding the outer surface of the first sheet to a surface of a plate after the grooves are formed, and removing the backing sheet from the first sheet and the excess of the first sheet from the plate after the second bonding step leaving those sections of the first sheet bonded to the plate which define the counter pattern to form a cutting and creasing plate.
Claim 2
Independent Claim
133 words
A method of producing a cutting and creasing plate having a counter pattern thereon for die cutting operations comprising the steps of bonding a first sheet from which the counter pattern is to be formed to a backing sheet, forming grooves in the first sheet in accordance with the desired counter pattern, which grooves extend completely through the first sheet but not completely through the backing sheet, bonding the outer surface of the first sheet to a surface of a plate after the grooves are formed, and removing the backing sheet from the first sheet and the excess of the first sheet from the plate after the second bonding step leaving those sections of the first sheet bonded to the plate which define the counter pattern to form a cutting and creasing plate.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein the first sheet is metal.
Claim 4
Dependent Claim
11 words
The method of claim 1 wherein the first sheet is aluminum.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein the cutting plate is flat.
Claim 6
Dependent Claim
11 words
The method of claim 1 wherein the cutting plate is arcuate.
Claim 7
Dependent Claim
28 words
The method of claim 1 wherein the bond between the first sheet and the plate is stronger than the bond between the first sheet and the backing sheet.
Claim 8
Dependent Claim
26 words
The method of claim 1 wherein the groove forming step further comprises cutting the grooves in response to a tape controlled input defining the groove pattern.
Claim 9
Dependent Claim
15 words
The method of claim 1 wherein the grooves are cut partially into the backing sheet.
Claim 10
Dependent Claim
35 words
The method of claim 1 wherein each of the bonding steps further comprises applying adhesive to the surfaces to be bonded, pressing these surfaces together, and allowing the adhesive to set to form the bond.
Claim 11
Dependent Claim
13 words
The method of claim 1 wherein the plate is made of hard steel.
