Abstract
Abstract A buffing member comprising a multiplicity of thin, flexible elements secured for rotation about an axis and adapted to wipe across a workpiece wherein each element comprises a substrate in the form of a sheet member of a fibrous mesh, synthetic resinous elastomeric substance comprising elastomeric foam permanently bonded in and to the mesh, and a distribution of abrasive substance permanently bonded to the foam.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
A buffing member comprising a multiplicity of thin, flexible elements secured for rotation about an axis, and adapted to wipe across a workpiece, each of said elements comprising a substrate in the form of a sheet member of a fibrous mesh, synthetic resinous elastomeric substance permanently bonded in and to said mesh comprising elastomeric foam, said foam bonded in and to said fibrous mesh, and a distribution of abrasive substance permanently bonded to said foam.
Claim 2
Dependent Claim
75 words
A buffing member comprising a multiplicity of thin, flexible elements secured for rotation about an axis, and adapted to wipe across a workpiece, each of said elements comprising a substrate in the form of a sheet member of a fibrous mesh, synthetic resinous elastomeric substance permanently bonded in and to said mesh comprising elastomeric foam, said foam bonded in and to said fibrous mesh, and a distribution of abrasive substance permanently bonded to said foam.
Claim 3
Dependent Claim
14 words
The buffing member of claim 1 wherein said foam is in a compressed state.
Claim 4
Dependent Claim
29 words
The buffing member of claim 2 wherein the major portion of the weight of said element, apart from said abrasive substance, is comprised of said synthetic resinous elastomeric substance.
Claim 5
Dependent Claim
14 words
The buffing member of claim 2 wherein abrasive substance is distributed through said mixture.
Claim 6
Dependent Claim
15 words
The buffing member of claim 2 wherein said fibrous mesh is formed of flexible fibers.
Claim 7
Dependent Claim
61 words
The buffing member of claim 2 wherein said elements comprise annular discs of said sheet material held in a drawn-together state at a radius smaller than the radius of said sheet material in the unassembled state, said annular sheet form elements thereby presenting a pleated self-renewing peripheral working edge comprised of said fine abrasive substance and said synthetic resinous elastomeric substance.
Claim 8
Dependent Claim
52 words
The buffing member of claim 2 wherein each of said elements comprises an additional substrate in the form of a sheet member of a fibrous mesh, said foam is bonded in and to said additional mesh, and said meshes are bonded to one another through foam sandwiched and bonded between said meshes.
Claim 9
Dependent Claim
93 words
A buffing member comprising a multiplicity of thin, flexible elements secured for rotation about an axis, and adapted to wipe across a workpiece, each of said elements comprising a substrate in the form of a sheet member of a fibrous mesh, synthetic resinous elastomeric substance permanently bonded in and to said mesh comprising a mixture of preformed elastomeric foam particles and elastomeric bonding agent, said foam particles bonded in and to said fibrous mesh in a compressed state, and a distribution of abrasive substance permanently bonded to said particles by said elastomeric substance.
Claim 10
Dependent Claim
93 words
A buffing member comprising a multiplicity of thin, flexible elements secured for rotation about an axis, and adapted to wipe across a workpiece, each of said elements comprising a substrate in the form of a sheet member of a fibrous mesh, synthetic resinous elastomeric substance permanently bonded in and to said mesh comprising a mixture of preformed elastomeric foam particles and elastomeric bonding agent, said foam particles bonded in and to said fibrous mesh in a compressed state, and a distribution of abrasive substance permanently bonded to said particles by said elastomeric substance.
Claim 11
Dependent Claim
16 words
The buffing member of claim 8 wherein said preformed elastomeric foam particles are formed of polyurethane.
Claim 12
Dependent Claim
61 words
The buffing member of claim 8 wherein each element includes an additional substrate in the form of a second sheet member of a fibrous mesh, and said form particles are bonded in and to said additional substrate in a compressed state and bonded to other particles between said substrates, and therethrough to particles bonded in and to the first said substrate.
