Abstract
In a method of forming an abrasive article a mesh material is applied with insulating material over areas which do not require abrasive, the insulating material being absorbed into the mesh material. The mesh material is then laid onto a surface of electrically conducting material and metal is electro-deposited onto the discrete areas of the mesh not bearing the insulating material. Abrasive is added so that it becomes embedded in the metal. The resulting material with metal and abrasive areas is stripped off the surface. The preferred insulating materials are ink screen printed onto the mesh, or hot melt adhesive perforated to define openings and then applied to the mesh to penetrate the mesh.
Claims12
In a method of making an abrasive article a length of mesh material is laid onto an electrically conducting surface, metal is electro-deposited through the mesh and onto discrete areas of the mesh material lying on said surface in the presence of abrasive material so that the abrasive material becomes embedded in the discrete areas of metal and the metal is attached to the mesh, and after application of the metal and abrasive to the mesh material the mesh material is stripped off said surface to constitute the abrasive article, wherein the improvement comprises applying the mesh material with insulating material over areas of the mesh material before application to said surface so that the insulating material penetrates into and fills the openings in the mesh over said areas and the metal is only deposited over the remaining discrete areas of the mesh.
