Abstract
Abstract A flexible abrasive member is formed by applying a layer of metal (15,16) to mesh material (12). Abrasive material (14) is embedded in the metal layer (15,16) during the deposition of the layer by an electrodeposition process. The mesh material (12) may be electrically non-conducting woven material and the metal layer (15,16) is deposited through the mesh material (12). In making the member the mesh material (12) is laid on a smooth, preferably curvilinear, surface (10) formed with areas (11) for receiving the metal layer (15, 16). Abrasive material (14) is introduced onto the surface at the beginning of the metal deposition process ortowards the end of the deposition process.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
53 words
A flexible abrasive member characterised by being formed of non-electrically conductive flexible mesh material (12) or flexible material having a non-electrically conducting coating, the material (12) being formed with a layer of metal (13; 15, 16) in which abrasive material (14) is embedded, and the layer of metal adhering to the mesh material.
Claim 2
Dependent Claim
53 words
A flexible abrasive member characterised by being formed of non-electrically conductive flexible mesh material (12) or flexible material having a non-electrically conducting coating, the material (12) being formed with a layer of metal (13; 15, 16) in which abrasive material (14) is embedded, and the layer of metal adhering to the mesh material.
Claim 3
Dependent Claim
24 words
An abrasive member according to claim 1 characterised in that the layer of metal (13 ; 15, 16) is formed by an electro-deposition process.
Claim 4
Dependent Claim
31 words
An abrasive member according to claim 1 or 2 characterised in that the layer of metal (13; 15, 16) is formed on selected discrete areas (17) of the mesh material (12).
Claim 5
Dependent Claim
44 words
An abrasive member according to any one of the preceding claims characterised in that the layer of metal (13 ; 15, 16) extends through the mesh material (12) from one side to the other so that the mesh material is embedded in the metal.
Claim 6
Dependent Claim
48 words
An abrasive member according to any one of the preceding claims characterised in that the abrasive material (14) is located to one side of the mesh material (12) and lies on the surface of the metal layer (15, 16) at said one side of the mesh material (12).
Claim 7
Dependent Claim
64 words
b. A method of making a flexible abrasive member characterised by laying a length of flexible mesh material (12) having non-electrically conducting properties or having a non-electrically conductive coating onto a smooth electrically-conductive surface (lO) and depositing a layer of metal (13;15,16) onto the surface and thereby onto the mesh material in the presence of abrasive material which thereby becomes embedded in the metal.
Claim 8
Dependent Claim
64 words
b. A method of making a flexible abrasive member characterised by laying a length of flexible mesh material (12) having non-electrically conducting properties or having a non-electrically conductive coating onto a smooth electrically-conductive surface (lO) and depositing a layer of metal (13;15,16) onto the surface and thereby onto the mesh material in the presence of abrasive material which thereby becomes embedded in the metal.
Claim 9
Dependent Claim
17 words
A method according to claim 6 characterised in that the metal layer (13;15,16) is formed by electro-deposition.
Claim 10
Dependent Claim
41 words
A method according to claim 7 characterised in that the smooth surface (10) is applied with electrically insulating material over selected areas of the surface so that the metal layer is deposited only over remaining discrete areas (11) of the surface.
Claim 11
Dependent Claim
32 words
A method according to claim 6, 7 or 8 characterised in that the smooth surface (10) is of curvilinear form and the mesh material (12) is applied under tension to the surface.
Claim 12
Dependent Claim
38 words
A method according to claim 9 characterised in that the smooth surface (10) is cylindrical and of stainless steel treated over said remaining areas (ll) to prevent adhesion of the metal layer (13; 15, 16) to the surface.
Claim 13
Independent Claim
34 words
A method according to any one of claims 6 to 10 characterised in that abrasive material (14) is present on the smooth surface (10) at the commencement of deposition of metal on said surface.
Claim 14
Independent Claim
61 words
A method according to any one of claims 6 to 10 characterised in that a metal layer (15) is deposited on the smooth surface (10) in the absence of abrasive material and a further layer (16) of metal is deposited on the first layer (15) in the presence of abrasive material to embed the abrasive material in the further layer (15).
