Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A method of manufacturing an abrasive product comprising, providing a conductive member with a surface thereon for attachment of abrasive particles, masking off predetermined desired surface portions on the backing member to thereby leave exposed spaced apart portions on the backing, a significant plurality of said abrasive grit particles positioned on each said exposed portions, bonding generally non-ferromagnetic abrasive grit particles to the exposed portions subsequent to the masking, said bonding being effected by a deposited metal plating technique of either the electrolytic, electroless, or vacuum deposition type and, said grit particles and said metal plating being applied to the product generally simultaneously in a generally static plating technique.
Claim 2
Independent Claim
109 words
A method of manufacturing an abrasive product comprising, providing a conductive member with a surface thereon for attachment of abrasive particles, masking off predetermined desired surface portions on the backing member to thereby leave exposed spaced apart portions on the backing, a significant plurality of said abrasive grit particles positioned on each said exposed portions, bonding generally non-ferromagnetic abrasive grit particles to the exposed portions subsequent to the masking, said bonding being effected by a deposited metal plating technique of either the electrolytic, electroless, or vacuum deposition type and, said grit particles and said metal plating being applied to the product generally simultaneously in a generally static plating technique.
Claim 3
Dependent Claim
12 words
The invention of claim 1 wherein, said plating is a nickel plating.
Claim 4
Dependent Claim
45 words
The invention of claim 1 wherein, said backing member is embossed from a rearward side thereof to form said exposed portions on the opposite side into raised portions so that the grit particles bonded thereto are raised relative to the plane of the backing member.
Claim 5
Dependent Claim
21 words
The invention of claim 1 wherein, said backing member has an underlying support means to provide further support to said product.
Claim 6
Dependent Claim
21 words
The invention of claim 1 wherein, said backing member is made of either a metal sheet, or a perforated metal sheet.
Claim 7
Dependent Claim
99 words
The invention of claim 1 wherein, said masking is carried out with a removable masking material, said particles are diamond abrasive grit, said plating is a nickel plating, said backing member is embossed from a rearward side thereof to form said exposed portions on the opposite side into raised portions so that the grit particles bonded thereto are raised relative to the plane of the backing member, said backing member has an underlying support means to provide further support to said product, and said conductive backing member is made of either a metal sheet, or a perforated metal sheet.
Claim 8
Dependent Claim
9 words
The product made by the method of claim 1.
Claim 9
Dependent Claim
9 words
The product made by the method of claim 6.
Claim 10
Dependent Claim
30 words
The invention of claim 1 wherein said abrasive grit is at least one material selected from the group consisting of diamond, boron nitride, glass, sand, silicon carbide, or aluminum oxide.
Claim 11
Dependent Claim
30 words
The invention of claim 2 wherein said abrasive grit is at least one material selected from the group consisting of diamond, boron nitride, glass, sand, silicon carbide, or aluminum oxide.
